Hello!

To find the surface area of a rectangular prism you use the equation

SA = 2(wl + wh + lh)

SA is surface area
w is width
l is length
h is height

Put in the values you know

SA = 2(4.5 * 16 + 4.5 * 29 + 16 * 29)

Multiply

SA = 2(72 + 130.5 + 464)

Add

SA = 2(666.5)

Multiply

SA = 1333

The answer is 1333 cm squared

Hope this helps!

The scores of 1000 students on a standardized test are normally distributed with a mean of 50 and a standard deviation of 5. wha
ra1l [238]
We are looking to find P(X>60 students)

X is normally distributed with mean 50 and standard deviation 5

We need to find the z-score of 60 students 
Z= \frac{60-50}{5}=2

To find the probability of P(Z>2), we can do 1 - P(Z<2)
So we read the probability when Z<2 which is 0.9772, then subtract from one we get 0.0228

The number of students that has score more than 60 is 0.0228 x 1000 = 228 students

What is the sum of the arithmetic sequence 151, 137, 123,..if there are 26 terms?
ElenaW [278]
First term: a1 = 151
common difference: d = -14 (we decrease by 14 each time, eg, 151-14 = 137)

nth term of this arithmetic sequence is...
an = a1+d(n-1)
an = 151+(-14)(n-1)
an = 151-14n+14
an = -14n+165

This will be used in the formula below

Sn = n*(a1+an)/2
<span>Sn = n*(151+(-14n+165))/2
</span><span>S26 = 26*(151+(-14*26+165))/2 ... replace every n with 26
</span>S26 = -624

The final answer here is choice C) -624
