Answer:

Step-by-step explanation:

lateral area formula= 2h(l+w) -------> 2(5) x 16+4

16+4= 20. 2x5=10. 10 x 20= 200.

lateral area= 200m

surface area= 2(wh+lw+lh) ------> 2(4x5+16x4+16x5). solve for that you get 328 m

In a hypothetical study looking at the scores of 100 people in an entrance exam, it was determined that the average score was 95
blagie [28]

Answer: 0.0228

Step-by-step explanation:

Given : In a hypothetical study looking at the scores of 100 people in an entrance exam, it was determined that the average score was 95 with a standard deviation of 10.

i.e. \mu=95\ \ \&\ \sigma=10

Let x denotes the scores.

We assume that the scores are normally distributed.

Then, the proportion of individuals in this population have a score greater than 115 will be :-

P(x>115)=1-P(x\leq115)\\\\=1-P(\dfrac{x-\mu}{\sigma}

Hence , the proportion of individuals in this population have a score greater than 115 = 0.0228

Use the equation for the surface area of a cylinder, SA = 2^r2 + 2arh, where r is
Alenkinab [10]

Answer:

<h2> 8in</h2>

Step-by-step explanation:

the given formula in the question is not correct

here is the correct formula

S. A. =2πr^2 +2πrh

given that S.A=207.24

radius r= 3in

207.24=2*3.142*(3)^2 +2*3.142*(3)h

207.24=56.556 +18.852h

207.24-56.556=18.852h

150.684=18.852h

h=150.684/18.852

h=7.99

Approximately the height is 8in
