Answer:

24.

Step-by-step explanation:

The is the number of permutations of 3 digits from 4

Can someone help me please. I have to show my work.
madreJ [45]

Answer:

Step-by-step explanation:

1. P = (width + lengh) * 2 = (23 + 10) * 2 = 33 * 2 = 66

  A = width * lengh = 23 * 10 = 230

2. width = 7

 P = (width + lengh) * 2 = ( 7 + 9) * 2 = 16 * 2 = 32

For a recent report on sleep deprivation, the Centers for Disease Control and Prevention interviewed 11600 residents of Californ
Pani-rosa [81]

Answer:

H0: p1-p2=0

Ha: p1-p2≠0

This hypotheses can be written as

H0: p1=p2

Ha: p1 ≠p2  

Step-by-step explanation:

Here the claim is if these data provide strong evidence the rate of sleep deprivation is different for the two states which will be formulated as alternate hypothesis .

Ha: p1-p2≠0  

The null hypothesis is

H0: p1-p2=0  i.e these data  do not provide strong evidence the rate of sleep deprivation is different for the two states.

where p1  =   as population 1 of California

p2= as population 2 of Oregon

This hypotheses can be written as

H0: p1=p2

Ha: p1 ≠p2  

which will also give the same results as above and a two tailed test will be performed for both hypotheses.

A certain right triangle with integer side lengths has perimeter $72$. What is its area?
JulijaS [17]

Answer: 216 square units

====================================================

Explanation:

A common pythagorean triple you may be familiar with is the 3-4-5 right triangle. This has two legs of 3 and 4, and a hypotenuse of 5. The perimeter is 3+4+5 = 7+5 = 12. Note how this is a factor of 72.

If we multiply the perimeter (12) by 6, then 12*6 = 72. So we have scaled the triangle by a factor of 6. Each length is 6 times longer

the side length 3 becomes 3*6 = 18

the side length 4 becomes 4*6 = 24

the side length 5 becomes 5*6 = 30

The new perimeter is 18+24+30 = 42+30 = 72

The last step is to find the area. The two legs of this triangle are the base and height

area = 0.5*base*height

area = 0.5*18*24

area = 9*24

area = 216

-----

Or you could find the area of the 3-4-5 right triangle to get

area = 0.5*base*height = 0.5*3*4 = 6

then multiply by 36 to get 6*36 = 216. The 36 is the square of the scale factor 6 we applied above. The new lengths are 6 times longer, so the new area is 6^2 = 36 times larger.
