1.1 Calculate the value of L the maximum consumption in category 3​

Answer:

$3.50

Step-by-step explanation:

add up all the x's and distribute them starting from the outside until you get to the middle. if there is an odd number of x's (which there isn't), the last x to be placed will be on the spot that is the median. If there is an even number of x's, and they both land on the same spot, that spot will be the median, and if they are next to each other, the median will be between them.

Explanation:

The given statement is claiming something like [tex]P(X < 2)[/tex] produces a different result compared to [tex]P(X \le 2)[/tex]. The subtle difference of course is the "or equal to".

When talking about continuous random variables, the two values are the same. Why? Because probability of selecting *exactly* X = 2 is going to be zero. Think of a very very thin strip of height P(X = 2) and the width is approaching zero. The width is doing this because we're trying to pinpoint X = 2 itself. As you can see, this skinny rectangle will have its area approach 0. Ultimately, whether we compute [tex]P(X < 2)[/tex] or [tex]P(X \le 2)[/tex], it doesn't matter. They both produce the same result.

If you are a visual learner, consider the standard normal distribution. Now consider the task if shading to the left of z = 2. This area describes both probabiltiies mentioned above.

If X is a continuous random variable, then [tex]P(X < 2) = P(X \le 2)[/tex] and we can change the "2" to any number we want to have the same outcome.

Therefore, the original claim is false.

-------------------------

Extra info:

Now if X was discrete (say from the binomial distribution), then the two probabilities would be different. This is because

[tex]P(X < 2) = P(0) + P(1)\\\\P(X \le 2) = P(0) + P(1) + P(2)\\\\P(X < 2) \ne P(X \le 2) \ \text{only if X is discrete}[/tex]

We can see in this case that the second line has P(2) while the first one does not.

So the original claim would be true if we changed "continuous" to "discrete".

Ty total compensation for the week where he earns a base rate of $12 per hour and receive a weekly attendance award of $20 is $500.

Rate is the ratio between two related quantities in different units.

Therefore, he earn a base rate of $12 per hour and receives a weekly attendance award of $20.

If he works 40 hours a week, his compensation will be as follows:

let

y = total compensation

x = number of hours worked

Hence,

y = 12x + 20

y = 12(40) + 20

y = 480 + 20

y = $500

Therefore, Ty total compensation is $500.

Answer:

Step-by-step explanation:

Since you did not include what the point is that you are trying to label, I can only tell you which quadrant is which. The quadrants go from 1 to 4 in a counterclockwise direction, starting from the top right quadrant (or the +,+ quadrant). One easy way to remember which direction the quadrants go in is the letter C, as they follow the same path as that letter.

Draw a closed circle on -10 and in the direction all the way towards the right arrow.

Answer:

580.4 cm^2 to the nearest tenth.

Step-by-step explanation:

If we draw a perpendicular line from the top right vertex to the base we split the figure into 2 triangles and a rectangle in the center.

Left side triangle:

base = √(28^2 - 20^2)    (using Pythagoras theorem

= 19.600

So its area = 1/2 * 19.6 * 20 = 196 cm^2.

Right side triangle:

Base = √(30^2 - 20^2) = 22.361

Area = 1/2 * 22.361 * 20 = 223.61 cm^2

Rectangle:

Base of rectangle = 50 - 19.6 - 22.361 = 8.039.

Area = 8.039 * 20 = 160.78.

So the area of the whole figure

= 196 + 223.61 + 160.78

= 580.39 cm^2.

A geometric series is the sum of an unlimited number. The common ratio of the geometric sequence is 3.

A geometric series is the sum of an unlimited number of terms with a fixed ratio between them.

Given the value of a₁ is 10, while the value of a₅ is 810, therefore, the common ratio can be written as,

[tex]\dfrac{a_5}{a_4} \times \dfrac{a_4}{a_3} \times \dfrac{a_3}{a_2}\times \dfrac{a_2}{a_1} = r \times r \times r \times r\\\\\\\dfrac{a_5}{a_1} = r^4\\\\\\dfrac{810}{10} = r^4\\\\\sqrt[4]{81} = r\\\\r = 3[/tex]

Hence, the common ratio of the geometric sequence is 3.

Answer:

x = -17y/2+y

Step-by-step explanation:

Reorder the terms -7y = 2x + xy + 10y

Move the terms -7y = 2x + yx + 10y

Rewrite collect like terms -2x - yx = 10y + 7y

Divide both sides (-2 - y)x = 17y

simplify x = 17y/-2-y

Solution x = -17y/2+y

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

The total number of people who were surveyed are:

Total Number of people = 82 + 94 +18 + 46 + 48 + 91 = 379

Also, it is mentioned in the table that the number of females who prefers suspense movies is 18. Therefore, the probability that a person will be a female and prefer suspense movies will be,

[tex]\rm Probability = \dfrac{\text{Number of females who prefers suspense movies}}{\text{Total Number of people}}\\\\Probability = \dfrac{18}{379} = 0.047[/tex]

Write two ratios equal to each other :

12/5 = 8/x(second speed)

Cross multiply:

12x = 40

Divide both sides by 12:

X = 3.333 or 3 1/3 km/h

second speed = 3.33 ( as a decimal) or 3 1/3 ( as a fraction) km/h

Answer:

First number = 9

Second number = 7

Step-by-step explanation:

Let x be the first number and y be the second.

2x + y = 25

3x - y = 20

1) Add them together.

5x = 45

x = 9

2) Solve for y.

2(9) + y = 25

y=7

3) Check your work on the other equation.

3(9) - (7) = 20

27 - 7 = 20

20 = 20

Therefore the first number is 9 and the second number is 7.

Step-by-step explanation:

Just did the quiz

By evaluating the piecewise function, we will see that the brother owes $15.

The piecewise function is:

y = 26,   if 0 < h < 4

y = 26 + 5*(h - 4),  if 4 < h < 8

y = 60, if 8 < h

Barbara uses it for 3 hours, so we only need to use the first part for her, so she needs to pay $26.

Then the brother uses it for 4 hours (and we need to add the 3 hours that Barbara used it, so we have h = 7).

Then for the 7 hours the two brothers need to pay:

y = $26 + $5*(7 - 4) = $41

If we subtract the part that Barbara needs to pay we get.

$41 - $26 = $15

This means that the correct option is $15.

Answer:

Step-by-step explanation:

[tex](-1 (\frac{2}{3} - 4)) / (5/6)[/tex]

Let's solve for the numerator first:

PEMDAS says parenthesis first so...

2/3 - 4, we'll turn 4 into an improper fraction so it's easier

2/3 - 12/3 = -10/3

-1(-10/3) = (+)10/3

Now, we replace this as the numerator:

(10/3) / (5/6)

To divide, we multiply the first fraction by the reciprocal of the second:

(10/3) * (6/5) = 60/15

now simplify.....

60/15 = 4 or in other words, {15 * 4 = 60}

So, the answer is 4!
