Answer:

75π is the answer

Step-by-step explanation:

In term of pie is solving without multiplying with pie which is 3.14

A=πr2 x H

1) leave π alone solve for r2

The radius is 5  so 5 squared is 25 or 5x5=25

2) Just multiply 25 times the height which is 3 with pie

25x3=75

75π is the answer

Hopes this helps!

Answer:

<h2>V = 235.5 in³</h2>

Step-by-step explanation:

The formula of a volume of a cylinder:

V=\pi r^2H

r - radius

H - height

From the pictue we have r = 5in and H = 3in. Substitute:

x=\pi(5^2)(3)=\pi(25)(3)=75\pi\ in^3

\pi\approx3.14

Therefore

x=(75)(3.14)=235.5\ in^3

Divide 1.20m in the ratio 2:3:4 what's the answer
Vikki [24]
2 :3 :4 gives 9 shares  (2 + 3 + 4)

9 shares = 120cm
1 share = 120/9 cm = 13 1/3 cm  ( or 13.333)

2 shares = 26 2/3 cm
3 shares = 40 cm
4 shares = 53 1/3 cm

Fill in the table using this function rule.<br> y = 10x-3<br> X<br> -<br> 0
dexar [7]

Answer:

Step-by-step explanation:

<em>y</em> = 10(- 1) - 3 = <em>- 13</em>

<em>y</em> = 10(0) - 3 = <em>- 3 </em>

<em>y</em> = 10(1)  - 3 =<em> 7 </em>

<em>y</em> = 10(5) - 3 = <em>47</em>

As a​ follow-up to a report on gas​ consumption, a consumer group conducted a study of SUV owners to estimate the mean mileage f
kondor19780726 [428]

Answer:

The 95​% confidence interval estimate for the mean highway mileage for SUVs is (18.29mpg, 20.91mpg).

Step-by-step explanation:

Our sample size is 96.

The first step to solve this problem is finding our degrees of freedom, that is, the sample size subtracted by 1. So

df = 96-1 = 95

Then, we need to subtract one by the confidence level \alpha and divide by 2. So:

\frac{1-0.95}{2} = \frac{0.05}{2} = 0.025

Now, we need our answers from both steps above to find a value T in the t-distribution table. So, with 95 and 0.025 in the t-distribution table, we have T = 1.9855.

Now, we find the standard deviation of the sample. This is the division of the standard deviation by the square root of the sample size. So

s = \frac{5.6}{\sqrt{96}} = 0.57

Now, we multiply T and s

M = T*s = 1.9855*0.57 = 1.31

For the lower end of the interval, we subtract the mean by M. So 19.6 - 1.31 = 18.29

For the upper end of the interval, we add the mean to M. So 19.6 + 1.31 = 20.91

The 95​% confidence interval estimate for the mean highway mileage for SUVs is (18.29mpg, 20.91mpg).
