Answer:
A. 232 in²
B. 216 in²
Step-by-step explanation:
A. Box A is a cuboid/rectangular prism.
Surface area of box A = 2(LW + LH + WH)
L = 10 in
W = 2 in
H = 8 in
Surface area = 2(10*2 + 10*8 + 2*8)
= 2(20 + 80 + 16) = 2(116)
Surface area = 232 in²
B. Surface area of B = surface area of cube
Surface area of cube = 6s²
s = 6 in
Surface area = 6(6²)
= 6(36)
= 216 in²
Answer:
35.25
Step-by-step explanation:
There are 4 data:
262, 313, 393, and 323
The formula for MAD (mean absolute deviation) = 
Where x_i are the each individual values (stated)
XBar is the average value
n is the number of data
First, let's find XBar, or the average. We add up all the 4 numbers and divide by 4 to get:
XBar = (262+313+393+323)/4=322.75
<em>Now, let's calculate MAD:</em>
<em>MAD = 
</em>
<em />
<em>MAD = 35.25</em>
Answer:
d
Step-by-step explanation:
The expected value of the discrete distribution is of 20.97, hence option C gives the correct answer.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability.</u>
Hence, according to the table, the expected value is given by:
E(X) = 12 x 0.08 + 18 x 0.15 + 20 x 0.31 + 22 x 0.08 + 24 x 0.15 + 25 x 0.23 = 20.97.

Based on my information, I believe that this would actually be a statistical because the question contains extra information that would help you narrow down the answer. The question could have been a lot easier, such as: "how much do horses weigh", but it does not, it
contained extra data that would help answer the question to the point.
