Answer:

Choice B) B \sqrt{29} 29 ​ square root of, 29, end square root = √29

Step-by-step explanation:

When given coordinates, the distance between those points(coordinates) is calculated as:

Distance = √(x2 - x1)² +(y2 - y1)²

Given(x1, y1), (x2, y2)

Fromm the question, we are given points(4,7) and (2,2)

Distance = √(x2 - x1)² +(y2 - y1)²

= √(2 - 4)² + (2 - 7)²

= √-2² + -5²

= √4 + 25

= √29

Therefore, Choice B is the answer = √29

Answer:

Tn = -6 + (n - 1)(-4)

Step-by-step explanation:

The explicit formula is this: Tn = a + (n - 1)*(d), where 'a' is the first term and 'd' is the common difference.

The first term is given to you and that is -6.

The common difference is -4 because:

d = -10 - (-6)

d = -10 + 6

d = -4

Hence: Tn = -6 + (n - 1)(-4)

Answer:

115

Step-by-step explanation:Beacsue that is way smaller than usal...the angle is 180 degress so if you do 55+65=120 so it defintly isn't 120 because that is correct so ya.

Answer:

[tex]\huge\boxed{y=-16}[/tex]

Step-by-step explanation:

We have to note that this represents a proportional relationship. This means that every time x increases by 1, y will increase by a proportional value.

In order to solve for proportions, we can create a proportion fraction which basically puts two variables over each other. Let's put x over y.

[tex]\frac{x}{y}[/tex]

We know that in the first fraction, x=6 and y=24.

[tex]\frac{6}{24}[/tex]

And we know that x=-4 but we have an unknown y value.

[tex]\frac{-4}{y}[/tex]

We can now set these proportions equal to each other and solve for the missing y using cross products.

Answer:

25 [tex]\frac{5}{11}[/tex]

Step-by-step explanation:

This is the answer because:

1) You have to convert 3 [tex]\frac{7}{11}[/tex] to an improper fraction. You can do this by multiplying 11 and 3 (the denominator and the whole number) then add 7 (the numerator). This equals to [tex]\frac{40}{11}[/tex].

2)  [tex]\frac{40}{11}[/tex] x [tex]\frac{7}{1}[/tex] = [tex]\frac{280}{11}[/tex]

3) Finally. convert [tex]\frac{280}{11}[/tex] to an mixed fraction which is 25 [tex]\frac{5}{11}[/tex]

Therefore, the answer is 25 [tex]\frac{5}{11}[/tex]

Answer:

x = -7

Step-by-step explanation:

Solve for x:

2 x + 3 = x - 4

Hint: | Move terms with x to the left-hand side.

Subtract x from both sides:

(2 x - x) + 3 = (x - x) - 4

Hint: | Combine like terms in 2 x - x.

2 x - x = x:

x + 3 = (x - x) - 4

Hint: | Look for the difference of two identical terms.

x - x = 0:

x + 3 = -4

Hint: | Isolate terms with x to the left hand side.

Subtract 3 from both sides:

x + (3 - 3) = -3 - 4

Hint: | Look for the difference of two identical terms.

3 - 3 = 0:

x = -3 - 4

Hint: | Evaluate -3 - 4.

-3 - 4 = -7:

Answer: $9

Step-by-step explanation:

Let the cost for adults be a

Let the cost for students be b.

The first van transported 2 adults and 5 students and cost $77. This will be:

2a + 5b = $77

The second van transported 2 adults and 7 students and cost $95. This will be:

2a + 7b = $95

2a + 5b = 77 ...... equation i

2a + 7b = 95 ........ equation ii

Subtract equation ii from I

-2b = -18

b = 18/2

b = $9

An student cost $9

Put the value of b into equation i

2a + 5b = 77

2a + 5(9) = 77

2a + 45 = 77

2a = 77 - 45

2a = 32

a = 32/2

a = 16

An adult costs $16

Answer:

84 minutes to 276 minutes

Step-by-step explanation:

Chebyshev's theorem states that:

At least 3/4(75% ) of data falls within 2 standard deviation from the mean - that means between μ - 2σ and μ + 2σ

At least 8/9(88.89)% of data falls within 3 standard deviations from the mean - between μ – 3σ and μ + 3σ .

Where k > 1 , 1 - 1/k²

k is 2, it is 75% and when k is 3 it is 88.89%

Americans spend an average of 3 hours per day online. If the standard deviation is 32 minutes, find the range in which at least 88.89% of the data will lies

Step 1

Convert 3 hours to minutes

1 hour = 60 minutes

3 hours = x

Cross Multiply

= 3hours × 60 minutes/1 hour

= 180 minutes

We know from Chebyshev's theorem that:

At least 8/9(88.89)% of data falls within 3 standard deviations from the mean - between μ – 3σ and μ + 3σ .

Hence

μ = 180 minutes, σ =32 minutes

μ – 3σ

= 180 - 3(32)

= 180 - 96

= 84 minutes

μ + 3σ

= 180 + 3(32)

= 180 + 96

= 276 minutes

Therefore the range in which at least 88.89% of the data will lie is 84 minutes to 276 minutes

Got it right on edge2020

The sine function that models the person’s blood pressure will be f(x) = 30 sin(Πx/5) + 90.

Function is a relationship between two sets X and Y where Set X is called domain and set Y is called codomain.

For example f(x)= sin x+ cos x

We have,

The Blood pressure of patient with the heart rate = 70 beats/ minute

And,

In next 10 minutes,

The maximum blood pressure i.e. (a + d) = 120 mm/Hg

The maximum blood pressure i.e. (-a + d) = 60 mm/Hg

So,

Sine function works on;

f(x) = a sin(bx + c) +d

So,

Now,

Adding Maximum and Minimum blood pressure,

i.e.

(a+d)+(-a+d) = 120 + 60

⇒a + d - a + d = 180

⇒ 2d = 180

d =90

So,

NOw, substituting this value in maximum blood pressure,

i.e. (a + d) = 120

a + 90 =120

a = 30

we have time period = 10 minutes,

So,

2Π/b = 10

⇒ b = Π/5

So,

Count is started at 0.

So, c = 0,

Putting the above value,

f(x) = a sin(bx + c) +d

⇒f(x) = 30 sin(Πx/5 + 0) +90

⇒f(x) = 30 sin(Πx/5) +90

Therefore, the sine function that models the person’s blood pressure as a function of time (in minutes) will be f(x) = 30 sin(Πx/5) + 90.

#SPJ2

A complementary angle of another angle is the angle that when you add it to that angle, you get 90 degrees.

For example, we have angle A. When we add the complementary angle of angle A, you get 90 degrees. :)

So, what we can do for this problem is create an equation! :)

x + 70.2° = "an angle"

x = complementary angle

Notice: I put the 70.2° to show the difference between the complementary angle and the angle itself.

Now, we can make an equation!

(x + 70.2°) + x = 90

2x = 19.8

x = 19.8/2

x = 9.9 degrees

One angle is 9.9 degrees, and the other angle is x + 70.2 = 9.9 + 70.2 = 80.1 degrees. We can see that when we add 9.9 and 80.1 we get 90 degrees, and when you minus 9.9 from 80.1, you get 70.2. :)

Answer:

The correct answer is: The y-intercept is 4

Step-by-step explanation:

A. (correct) explanation-The y-intercept is the point where the line crosses the y-axis (vertical line). The y-intercept here is 4 because that is the point where the line crosses the y-axis

B: The x-intercept is 0 (wrong)

B is wrong because the x-intercept is the point where the line crosses the

x-axis (horizontal line)

C: (wrong) A savings account started with $8 in it

C is wrong because the initial amount is usually the y-intercept, but here the y-intercept is 4.

D: (wrong) It took 4 mins to run a mile

D is wrong because there should have been a point at the location (1,4) for this statement to be true, but there is no point there

Answer:

because the lines are parallel meaning they will never cross
