1. Mean.
2. <span>Standard deviation.
First we have to square each value and calculate the mean of that squares:
so the variance:
and the standard deviation:
</span>
I believe it should be B because it says one more than twice the number so that means addition. Also it says twice the number so that should be 2w.
I’m not 100% sure but it is my best guess
Part A
We have x = 4 and y = 3 paired up together.
This says that 4 pounds of potatoes cost $3
The price per pound (aka unit price) is y/x = 3/4 = 0.75 dollars = 75 cents.
Answer: 75 cents per pound
========================================
Part B
The ordered pair (8,6) means x = 8 and y = 6 pair up together.
So in this case, 8 pounds of potatoes cost $6.
notice how y/x = 6/8 = 3/4 = 0.75 dollars = 75 cents here as well. So we get the same unit cost.
Answer:
a) m∠6 = 55 and m∠8= 55 - 20 --> m∠8= 35 x = 55
b) m∠7 = 40 and m∠9 = 140 x = 40
c) m∠8 = 46 and m∠7 = 46 x = 18
d) m∠6 = 63 and m∠7 = 27 x = 9
(just like the note says at the top each one is a different problem hence the different answer or each angle even if its the same one)
