Which of the following would increase if the professional football players were removed from the data set?

Mathematics
1 answer:
marshall27 [118]2 years ago
5 0

Answer:

the standard deviation of the residuals

Step-by-step explanation:

The removal of the professional football players will cause the correlation, and consequently r2 to become closer to 0 due to the fact that the high school athletes tend to show no association between the number of energy drinks consumed and the number of pull ups that can be done. The slope of the regression line will also be nearly 0 without the professional football players. The standard deviation of the residuals, however, will increase without the presence of the professional football players because the remaining scatter about the new regression line will be greater due to the loss of the 4 professional football players which all had small residuals.

HELP ME <br> solve for the right triangle
VikaD [51]

Answer:

see explanation

Step-by-step explanation:

Using the cosine and tangent ratios in the right triangle

cos41° = \frac{adjacent}{hypotenuse} = \frac{VW}{VX} = \frac{7}{VX}

Multiply both sides by VX

VX × cos41° = 7 ( divide both sides by cos41° )

VX = \frac{7}{cos41} ≈ 9.3

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

tan41° = \frac{opposite}{adjacent} = \frac{WX}{VW} = \frac{WX}{7}

Multiply both sides by 7

7 × tan41° = WX, thus

WX ≈ 6.1

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

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180° for ∠ X

∠ X = 180° - (90 + 41)° = 180° - 131° = 49°

Ethan writes 2/3 of a page in 5/12 of a minute. How much time does it take him to write one page
Nataliya [291]
2/3 of a page in 5/12 of a minute

Multiply both fractions by 3/2

\frac{2}{3} \times \frac{3}{2} = 1

\frac{5}{12} \times \frac{3}{2} = \frac{5}{4} \times \frac{1}{2}=\frac{5}{8}

So, Ethan can read 1 page in 5/8 of a minute.

Surface Area of Cylinders
lidiya [134]

Answer: 1639.08

Step-by-step explanation: To find the surface area of a cylinder, multiply 2(3.14)times the radius squared. Your answer is 508.68. Then multiply 2(3.14)times the radius and the height. You'll get 1130.08. add the answers you got from both equations together. That's the surface area of your cylinder. If you have any more questions, please let me know.
