Answer:
A and B
Step-by-step explanation:
The surface area is found by calculating the 6 faces of a 3-d object. Since A and B are the only ones that cause you to use the whole object for the given task the answers are A and B.
You can surely do this! First, find the mean of the 8 given scores. Add up these scores and then divide the result (sum) by 8 to obtain the mean.
raw score - mean
The formula for "z-score" is z = -------------------------
std. deviation
You'll need to calculate the standard deviation of these 8 scores.
73 - mean
Then, as an example: raw score 73 translates into z-score z = ---------------
std. dev.
Answer:
-15 + 10x
or
10x - 15
(either one works)
Step-by-step explanation:
You mean you just want me to expand it?
Ok.
Multiply -5 by 3 and -2x.
(-5)(3) = -15
(-5)(-2x) = +10x
Add those together:
-15 + 10x
or
10x - 15
Y=18
x=6
following since they vary directly it would be in
y=mx form
18=m(6)
6*3=18
your answer is y=3x
