Nastasia [14]

Answer:

h=5in

Step-by-step explanation:

The following areas are equal:

1. Front and Back.

2. Left and right.

3. Top and Bottom.

Therefore, we calculate 3 areas and

multiply each by 2 to get the 6 areas:

As=2(3*h) + 2(10*h) + 2(10*3)=1901n^2.

6h + 20h + 60 = 190,

26h = 190 - 60 = 130,

h = 5in.

Answer: Option 'd' is correct.

Step-by-step explanation:

Since we have given that

Margin of error = 0.5 years

Standard deviation = 5

At 90% confidence, z = 1.645

We need to find the minimum size of the sample they must take.

So,

$n=(\dfrac{z\sigma}{E})^2\\\\n=(\dfrac{1.645\times 5}{0.5})^2\\\\n=270.6\\\\n\approx 271$

Hence, Option 'd' is correct.
