Alan found the distance between point A(-8, -4) and point B(3, -4). His worn is shown below. -8 to the y-axis=8 units. 3 to the y-axis=3 units. |-8| - |3| = 5 units from A to B. What error did Alan make? What is the actual distance from point A to point B?

Answers

Answer 1

Answer:

Step-by-step explanation:

Alan made an error in assuming that the distance between -8 and 3 on the x-axis is the same as the distance between -8 and the y-axis, and between 3 and the y-axis. This is not necessarily true, as the distance between two points on a coordinate plane is given by the Pythagorean theorem:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Using this formula, we can find the actual distance between points A and B:

distance = sqrt((3 - (-8))^2 + (-4 - (-4))^2)

distance = sqrt(11^2 + 0^2)

distance = sqrt(121)

distance = 11

So the actual distance between points A and B is 11 units.

Therefore, Alan's error was assuming that the distance between A and B is simply the difference in the x-coordinates, which is not the case.

Waffle Wonderland puts a 250-milliliter bottle of maple syrup on each one of their 16 tables. The owner is filling the syrup bottles before the restaurant opens. If the bottles are half full, how many liters would she need to fill the bottles?

Answers

Since there are 16 tables with 250-milliliter bottles on each, the total amount of syrup required for all the tables is:

250 mL/bottle x 16 bottles = 4,000 mL

Since the bottles are half full, the amount of syrup required to fill all the bottles would be:

4,000 mL ÷ 2 = 2,000 mL

Converting 2,000 mL to liters:

2,000 mL ÷ 1,000 mL/L = 2 liters

Therefore, the owner would need 2 liters of syrup to fill all the bottles.
Well, since there is 250mil bottles and 16 of them, there would be 4000mil, but since he only puts half in each bottle, there would only be 2000mil

2 PART QUESTION PLS HELP Harris has a spinner that is divided into three equal sections numbered 1 to 3, and a second spinner that is divided into five equal sections numbered 4 to 8. He spins each spinner and records the sum of the spins. Harris repeats this experiment 500 times.
Question 1
Part A

Which equation can be solved to predict the number of times Harris will spin a sum less than 10?

A) 3/500 = x/15

B) 12/500 = x/15

C) 12/15 = x/500

D) 3/15 = x/500

QUESTION 2
Part B
How many times should Harris expect to spin a sum that is 10
or greater?

_______

Answers

Harris should expect to spin a sum that is 10 or greater than 100 times.

How to solve

Part A:

To predict the number of times Harris will spin a sum less than 10, we need to find the probability of getting a sum less than 10 and multiply it by the total number of spins, which is 500.

The possible outcomes of the first spinner are 1, 2, and 3, and the possible outcomes of the second spinner are 4, 5, 6, 7, and 8.

The minimum sum we can get is 1+4=5, and the maximum sum we can get is 3+8=11.

To get a sum less than 10, we can get:

1+4=5

1+5=6

1+6=7

1+7=8

1+8=9

2+4=6

2+5=7

2+6=8

2+7=9

3+4=7

3+5=8

3+6=9

There are 12 possible outcomes that result in a sum less than 10. So the probability of getting a sum less than 10 is 12/15, or 4/5.

To find the number of times Harris will spin a sum less than 10, we can use the equation:

probability of getting a sum less than 10 × total number of spins = x

So the equation that can be solved to predict the number of times Harris will spin a sum less than 10 is:

C) 12/15 = x/500

Part B:

To find the number of times Harris should expect to spin a sum that is 10 or greater, we can subtract the number of times he will spin a sum less than 10 from the total number of spins:

total number of spins - number of times he will spin a sum less than 10 = number of times he should expect to spin a sum that is 10 or greater

Substituting the values, we get:

500 - (12/15 × 500) = 500 - 400 = 100

So Harris should expect to spin a sum that is 10 or greater than 100 times.

To simplify the expressions for the minimum and maximum recommended widths of the space between 6-inch by 6-inch floor tiles, we can convert the mixed numbers to improper fractions and then find the least common multiple (LCM) of the denominators.

First, let's simplify the minimum recommended width of the space:

[tex]2-2 inch = 2 + 2/12 = 2 + 1/6 = (2*6 + 1)/6 = 13/6 inches[/tex]

Next, let's simplify the maximum recommended width of the space:

[tex]2-1 inch = 2 + 1/12 = 2 + 2/24 = (2*12 + 2)/24 = 26/12 = 13/6 inches[/tex]

A piece of property contains 1,758.1066 sq. yards. How many yards are on each side of the square?

Answers

Answer: approximately 41.96 yards

Step-by-step explanation:

If a square property contains 1,758.1066 square yards, then the area of the square is equal to this value.

Let x be the length of each side of the square. Then, the area of the square can be expressed as x^2.

So we have:

x^2 = 1,758.1066 sq. yards

Taking the square root of both sides gives:

x = √1,758.1066

x ≈ 41.96 yards

Therefore, each side of the square is approximately 41.96 yards long.

Each side of the square is approximately 41.9143 yards long.

suppose that a voting facility processes an average of 55 people per hour (throughput) and that, on average, it takes 30 minutes for each person to complete the voting process (flow time).

Answers

The required  average number of people completing voting at any given time as per given 55 people per hour is equals to 27.5.

Average throughput voting facility process = 55 people per hour,

Calculate the average processing time per person ,

⇒ Processing time per person = 1 hour / 55 people

⇒ Processing time per person = 0.01818 hours/person

Average time taken by each person to complete the voting process = 30 minutes  

Convert this to hours by dividing by 60,

⇒ Flow time per person = 30 minutes / 60

⇒ Flow time per person = 0.5 hours/person

Now,

Average number of people in the voting facility using Little's Law,

which states that the average number of items in a system is equal to the average throughput multiplied by the average flow time.

⇒ Average number of people in facility = Average throughput x Average flow time

⇒ Average number of people in facility = 55 people/hour x 0.5 hours/person

⇒ Average number of people in facility = 27.5 people

Therefore, on average there are 27.5 people in the voting facility at any given time.

A chemical company makes two brands of antifreeze. The first brand is 30 pure antifreeze, and the second brand is 80 pure antifreeze. In order to obtain 150 gallons of a mixture that contains 40 pure antifreeze, how many gallons of each brand of antifreeze must be used?

Answers

Answer: Let x be the number of gallons of the first brand (30% pure antifreeze) that needs to be mixed, and let y be the number of gallons of the second brand (80% pure antifreeze) that needs to be mixed. We want to find the values of x and y that satisfy the following conditions:

The total amount of antifreeze mixed is 150 gallons: x + y = 150

The resulting mixture is 40% pure antifreeze: 0.3x + 0.8y = 0.4(150)

We have two equations with two unknowns, so we can solve for x and y. We'll use the first equation to solve for y in terms of x:

y = 150 - x

Substituting this expression into the second equation gives:

0.3x + 0.8(150 - x) = 60

Simplifying and solving for x:

0.3x + 120 - 0.8x = 60

-0.5x = -60

x = 120

Substituting this value back into y = 150 - x gives:

y = 150 - 120 = 30

Therefore, we need to mix 120 gallons of the first brand and 30 gallons of the second brand to obtain 150 gallons of a mixture that contains 40% pure antifreeze.

A confidence interval is a range of values that is likely to contain the true population parameter, and a wider confidence interval allows for a greater chance of accurately capturing the true population parameter.

The use of 0.5 as an estimate of the sample proportion is most conservative because it produces the widest confidence interval.

A larger sample size is generally used when the confidence interval is wider, as it improves the precision of the estimate.

Using 0.5 as the estimated proportion will produce the widest confidence interval and thus, a larger sample size.

what is probability ?

The study of chance and uncertainty is covered in the mathematical field of probability. It is a way to gauge how likely something is to happen. Probability can be expressed as a number between 0 and 1, with 0 indicating that an occurrence is impossible, and 1 indicating that an event is certain. Probability is frequently employed in real-world situations to forecast the results of random occurrences like tossing a coin, rolling a die, or drawing cards from a deck. The probability of an occurrence is estimated by dividing the number of possible outcomes by the number of possible ways the event could occur.

given

a. We need to locate the region to the right of 307 under the normal distribution curve in order to determine the likelihood that a pregnancy would last 307 days or longer.

By standardizing the value of 307, we may make use of the standard normal distribution:

(X - mu) / sigma = z

z = (307 - 268) / 15\sz = 2.6

A basic normal distribution table or calculator can be used to determine that a z-score larger than 2.6 has a probability of about 0.0047.

Thus, the likelihood of a pregnancy lasting at least 307 days is roughly 0.0047, or 0.47%.

b. We must determine the gestational period that sets the lowest 3% of pregnancies apart from the others. The value with a cumulative probability of 0.03 to its left is this one.

The z-score for a cumulative probability of 0.03 can be calculated using a conventional normal distribution table or calculator. It is roughly -1.88.

To determine the corresponding length of pregnancy, we can apply the z-score formula:

z = (x - mu)/sigma -1.88 = (x - 268)/15 -28.2 = x - 268 x = 239.8

Thus, infants are deemed preterm if they arrive on or before 240 days (rounded to the next integer).

The option 2 is correct of given question ''All the powers have a value of 1 because the exponent is zero.''

What do you mean by Exponent?

An exponent is a mathematical notation that indicates the number of times a quantity is multiplied by itself. It is written as a superscript number to the right of the quantity being multiplied.

For example, in the expression 5³, 5 is the base and 3 is the exponent. This means that 5 is being multiplied by itself three times: 5 x 5 x 5, which equals 125.

The statement "All the powers have a value of 1 because the exponent is zero" describes what these four powers have in common.

When the exponent is zero, any number (except for 0) raised to the power of 0 equals 1. Therefore, 10⁰  = 1, (-2)⁰ = 1, and any non-zero number raised to the power of 0 equals 1.

There is no fractional value involved in this case, as raising a number to the power of zero does not involve any division.

What is height?

I believe you meant to ask about "height". Height is a measurement of how tall something is, typically referring to the distance from the ground or base to the top of an object. It can be measured in various units, such as feet, inches, meters, or centimeters. People often use height to describe the physical stature of individuals or objects, such as the height of a person, building, or tree.

by the question.

let's start by recalling the formula for the lateral surface area of a pyramid:

[tex]Lateral Surface Area = (1/2) x Perimeter of Base x Slant Height[/tex]

We are given that the lateral surface area is 120 cm2 and the base area is 64 cm2. Since the base is a square, we can find the length of one side by taking the square root of the area:

Side of Base = sqrt(64 cm2) = 8 cm

The perimeter of the base is then 4 times the length of one side:

[tex]Perimeter of Base = 4 x 8 cm = 32 cm[/tex]

Now we can substitute the values we have into the formula and solve for the slant height:

For the function p = 2 - 3q². what is the instantaneous rate of change function?​

Answers

Answer:

Step-by-step explanation:

To find the instantaneous rate of change function for the given function p = 2 - 3q², we need to find the derivative of the function with respect to q. The derivative gives us the slope of the tangent line to the curve at any point, which is the instantaneous rate of change at that point.

So, we can start by taking the derivative of the given function:

dp/dq = d/dq(2 - 3q²)

dp/dq = 0 - 3(2q)

dp/dq = -6q

Therefore, the instantaneous rate of change function for p = 2 - 3q² is given by:

In the given question angle a= 60° and b= 120° by exterior angle theorem

How are exterior angles determined?

When a triangle's side is extended to make an angle outside the triangle, the external angles of the triangle are formed. We can use the formula below to determine the size of an external angle:

Sum of Measurements of Distant Interior Angles = Measure of Exterior Angle

The two interior angles that are not directly close to the external angle being measured are known as the remote interior angles. Remote internal angles are angles at vertices A and B if we extend the side AB to generate an exterior angle at vertex C in a triangle with vertices A, B, and C.

Measure of Interior Angle at Vertex A + Measure of Interior Angle at Vertex B = 180 degrees, where Measure of Exterior Angle at Vertex C = 180 degrees.

The derivative of the function is (5/2)x² - 2, the critical points are [tex](\frac{2\sqrt{5} }{5}, -\frac{8\sqrt{5} }{15}), (-\frac{2\sqrt{5} }{5}, \frac{8\sqrt{5} }{15})[/tex], the points of inflection of the function is at (0,0)

What is the value of f'(x)

(a) The derivative of f(x) is f'(x) = (5/2)x² - 2.

(b) The critical points occur where f'(x) = 0 or where f'(x) is undefined.

Setting f'(x) = 0, we get (5/2)x² - 2 = 0,

[tex](\frac{2\sqrt{5} }{5}, -\frac{8\sqrt{5} }{15}), (-\frac{2\sqrt{5} }{5}, \frac{8\sqrt{5} }{15}[/tex]

(c) f'(x) = (5/2)x² - 2 is positive when x > (2√5)/5 and negative when x < (-2√5)/5. Therefore, f(x) is increasing on the interval

[tex](-\infty, -\frac{2\sqrt{5} }{5}), (\frac{2\sqrt{5} }{5}, \infty)\\[/tex] and it decreases along the interval of

[tex](-\frac{2\sqrt{5} }{5}, \frac{2\sqrt{5} }{5})[/tex]

(d) The second derivative of f(x) is f''(x) = 5x

(e) f''(x) is positive when x > 0 and negative when x < 0. Therefore, f(x) is concave up on the interval (0, infinity) and concave down on the interval (-infinity, 0).

(f) The points of inflection for f(x) are (0,0)

what is pythagoras theorem ?

A right triangle's hypotenuse (the side that faces the right angle) has a square length that, according to Pythagoras' Theorem, is equal to the sum of the squares of the lengths of the other two sides (the legs). Formally, Pythagoras' theorem asserts that if a right triangle has legs of lengths a, b, and c, and a hypotenuse of length c, then:

[tex]a^2 + b^2 = c^2[/tex]

Pythagoras, an ancient Greek mathematician, is credited with discovering and proving this theorem, therefore it bears his name.

given

The Pythagorean theorem can be used to determine the length of the omitted side. Let x be the length of the side that is missing. The right triangle that results has a hypotenuse that is top-bottom in length and legs that are x and slant in length. This can be expressed as:

x2 + slant2 = (top - bottom)2

$$

To put it simply, we have:

\begin{align*} \s(top - bottom) (top - bottom)

2 &= x 2 + slant 2, top 2 - 2top "cdot bottom + bottom 2 - slant 2," x 2 &= "sqrt" top 2 - 2top "cdot bottom + bottom 2 - slant 2," and "end align"

begin-aligning* x = sqrt((5),2,5,8,and(8),2,-7,2). sqrt = 25 - 80 + 64 - 49; sqrt = 40; sqrt = boxed 2i sqrt 10; end align;

Ashley invested $59,000 in an account paying an interest rate of 3 1/8% compounded daily. Fwam invested $59,000 in an account paying an interest rate of 2 3/4% compounded annually. . After 15 years, how much more money would Ashley have in her account than Fwam, to the nearest dollar?

Answers

The difference between the balances of Ashley and Fwam after 15 years is given as follows:

$5,650. (Ashley will have $5,650 more than Fwam).

What is compound interest?

The amount of money earned, in compound interest, after t years, is given by:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

In which:

P is the principal, which is the value of deposit/loan/....r is the interest rate, as a decimal value.n is the number of times that interest is compounded per year, annually n = 1, semi-annually n = 2, quarterly n = 4, monthly n = 12.

Hence Ashley's amount after 15 years is given as follows:

A(15) = 59000 x (1 + 0.03125/365)^(365 x 15)

A(15) = $94,280.

Fwam's amount is given as follows:

F(15) = 59000 x (1 + 0.0275)^(15)

F(15) = $88,630.

Then the difference is of:

94280 - 88630 = $5,650.
