Answer:
hi! so we have 2 points right? you will need to use something called the slope formula y2-y1/x2-x1 we're subtracting our y values of both points and x values of both points while dividing them this gives us a slope of a line
now I want you to label before you do this in your head! it can get confusing to think about it so label label (x1-1,y1 4) (x2 14,y2 -2) now you have them labeled this parts easy! use the formula -2-4/14--1 okay now use your calculator you get -2/5 and now you have your m or slope!
memorize y2-y1/x2-x1 now! it will save you!
Step-by-step explanation:
-50 + 17 = - 33
-33 + 17 = -16
- 16 +17 =1
This is arithmetic sequence, where 1st term is -50,
and common difference is 17.
Formula for the term of arithmetic sequence
a(n) = a(1) +d(n-1) = -50 +17(n-1) = -50 +17n - 17 = -67 +17n
So, we can write a formula
a(n) = -67 +17n
It's saying that 95% of the time the comparison from test to retest is 96% reliable.
so I would take (0.95+0.96)÷2= 0.955
then 73×0.955=69.715
then 73-69.715=3.285
so I would range the possible true score between 69.715 and 76.285
also written as 73 ± 3.285
Answer:
A. 3
Step-by-step explanation:
(-m)^3 n if m = 2 and n = -24
Plug in
(-2)^-3 (-24)
= (-24) / (-2)^3
= -24 / -8
= 3
