Circumference = 2 x Pi x R

if we use 3.14 as pi, you would do 2 x 3.14 x 4, which would equal 25.12, i’m not sure if it was meant to be rounded to 25, but none of the multiple choice answers would be correct

Which of the following is the graph of y = negative 4 StartRoot x EndRoot? On a coordinate plane, an absolute value curve opens

Darya [45]

Answer:

see the procedure

Step-by-step explanation:

we have

$y=-4\sqrt{x}$

we know that

The domain of a function is the set of all possible values of x

The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.

In this problem

The domain for x is the interval [0,∞)

All real numbers greater than or equal to zero

The range for y is the interval (-∞,0]

All real numbers less than or equal to zero

The graph in the attached figure

therefore

On a coordinate plane, an absolute value curve opens down and to the right in quadrant 4 and starts at (0, 0)

1. Volume of 1 tennis ball = volume of sphere = 33.51 in.³

2. Volume of the cylinder = 150.8 in.³

3. Amount of space not occupied by the tennis ball = Volume of cylinder - 3(volume 1 tennis ball) = 50.27 in.³

<h3>What is the Volume of a Cylinder and Volume of a Sphere?</h3>

Volume of Cylinder = πr²h
Volume of Sphere = 4/3πr³

Diameter of the tennis ball = 4 in. (given)

1. Volume of 1 tennis ball = volume of sphere = 4/3πr³

r = 1/2(4 in.) = 2 in.

Volume of 1 tennis ball = 4/3π(2)³ = 33.51 in.³

2. Volume of the cylinder = πr²h

Radius of the cylinder (r) = 1/2(4 in.) = 2 in

Height of the cylinder (h) = 3(4 in.) = 12 in

Volume of the cylinder = πr²h = π(2²)(12) = 150.8 in.³

3. Amount of space not occupied by the tennis ball = Volume of cylinder - 3(volume 1 tennis ball)

= 150.8 - 3(33.51) = 50.27 in.³

The Wanting Recognition (WR) Scale provides a quantitative measure of a person's level of need for approval and sensitivity to s

levacccp [35]

Answer:

99% of the confidence level of the mean WR score for all convicted drug dealers

(37.4544, 40.5456)

Step-by-step explanation:

Step(i):-

Given that the sample size 'n' = 100

Given that the mean of the sample(x⁻) = 39

Given a standard deviation of the sample (σ) = 6

Level of significance = 0.01 or 99%

Step(ii):-

99% of the confidence level of the mean WR score for all convicted drug dealers

$(x^{-} - Z_{0.01} \frac{S.D}{\sqrt{n} } ,x^{-} + Z_{0.01} \frac{S.D}{\sqrt{n} })$

$(39 -2.576 \frac{6}{\sqrt{100} } ,39 + 2.576 \frac{6}{\sqrt{100} })$

(39 - 1.5456 , 39+1.5456)

(37.4544, 40.5456)

Final answer:-

99% of the confidence level of the mean WR score for all convicted drug dealers

(37.4544, 40.5456)
