Answer:
30
Step-by-step explanation:
Here, it is given that the Z – score corresponding to the score X = 45 is 1.5 and the Z – score corresponding to the score X = 40 is...
Z =
So:
1/ 1.5 =
and 1 =
. solve the both equations, we found out:
<=> S = 10
=> M = 30
Hence, mean is:
M = 45 -1.5S = 45 - 1.5 (10) = 30
Answer:
1
Step-by-step explanation:
The slope of the line is 1. To find slope use the formula
, this calculates the change in y over the change in x. So plug in the known values
, this equals 3/3 or 1. This means every time y increases by 1, x will also increase by 1.
Answer:
(3.5, 3) and (0,-4)
Step-by-step explanation:
Zeros are the points that are on the x-intercept. The points not on the x-intercept are (3.5, 3) and (0,-4)
Y=x+1
You can solve using slop formula
Answer:
-7b+3
Step-by-step explanation:
first step you will find numbers if you take -2.2 to get those numbers
