Lets BC =x
8/5 = 32/x
8x =32 * 5
8x = 160
x = 160/8
x = 20
answer
BC = 20
Answer:
14 / 1/3
Step-by-step explanation:
Answer: (0.685, 0.735)
Explanation:
First, we will compute the confidence level of the given:
![\text{ Confidence Level }=\frac{36}{40}\times100\%=90\%](https://tex.z-dn.net/?f=%5Ctext%7B%20Confidence%20Level%20%7D%3D%5Cfrac%7B36%7D%7B40%7D%5Ctimes100%5C%25%3D90%5C%25)
They gave us a margin of error of 0.025. From the given, we know that p=71%=0.71.
The confidence interval would then be:
![\begin{gathered} (p-E,p+E) \\ =(0.71-0.025,0.71+0.025) \\ =(0.685,0.735) \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%28p-E%2Cp%2BE%29%20%5C%5C%20%3D%280.71-0.025%2C0.71%2B0.025%29%20%5C%5C%20%3D%280.685%2C0.735%29%20%5Cend%7Bgathered%7D)
Therefore, the confidence interval would then be (0.685, 0.735)
Answer:
6.75 ft^2
Step-by-step explanation:
The area of the seat can be calculated as follows
a + b/2 × h
6+3/2 × 1.5
9/2 × 1.5
4.5× 1.5
= 6.75 ft^2
Hence the area of the seat is 6.75ft^2
Ur basically going to do a reflection on the shape
It would not change the relationship between the angles or sides and the shape is completely the same but just mirrored
