Mean 60 - 2(0.9) = 58.2
58.2 is 2 standard deviations from the mean.
The equal expression to tan155 is -tan25.
Hope this helps :)
Answer:
y = 2
Step-by-step explanation:
For the equation x - y = -1, if x = 1,
then we would plug that in to solve for the y value
1 - y = -1
Subtract 1 from both sides to find y
-y = - 2
Divide by -1 to find y
y = 2.
To double check our answer we would plug in our x-value and y-value into the equation
1 - 2 = -1
This is true, so our answer is y = 2
