Answer:
c=o.75
Step-by-step explanation:
Answer:
54
Step-by-step explanation:
Well, divide 300 by 100, which gets you 3. So 3 feet of book shelves = 1%
So 3x18=54
The answer is 90% of the crime is between 48.63 and 51.37
<h3>How to solve for the confidence interval</h3>
The sd = 5 months
n = 36
Mean length = 50
1- 0.90
= 0.1
Critical value = alpha/2 = 1.645
Margin of error
E = 1.645 x 5/√36
= 1.37
<h3>The upper and lower limits are</h3>
50 - 1.37 + 50 + 1.37
= (48.63, 51.37)

we are given that
two triangles are similar
so, the ratio of their sides must be same
we get
![\frac{2}{6} =\frac{x}{x+2}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B6%7D%20%3D%5Cfrac%7Bx%7D%7Bx%2B2%7D)
now, we can solve for x
step-1: Cross multiply both sides
![2(x+2) =6x](https://tex.z-dn.net/?f=2%28x%2B2%29%20%3D6x%20)
step-2: Simplify left side
![2x +4 =6x](https://tex.z-dn.net/?f=%202x%20%2B4%20%3D6x%20)
step-3: Subtract both sides by 2x
![2x +4-2x =6x-2x](https://tex.z-dn.net/?f=%202x%20%2B4-2x%20%3D6x-2x%20)
![4 =4x](https://tex.z-dn.net/?f=%204%20%3D4x%20)
step-4: Divide both sides by 4
![x=1](https://tex.z-dn.net/?f=%20x%3D1%20)
so,
