It's difficult to spot what kind of help is needed.
There's no variable in that equation whose value needs to be found.
It appears to be simply a statement, saying that the tangent of 36 degrees
is (3 and 3/7) .
As such, it's false, since the tangent of 36 degrees is roughly 0.7265 .
What exactly is the question ?
T(s(x)) = -5
Substitute the value in for x and evaluate = -2
Answer:
0.03 is the probability that for the sample mean IQ score is greater than 103.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 100
Standard Deviation, σ = 16
Sample size, n = 100
We are given that the distribution of IQ score is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling =

P( mean IQ score is greater than 103)
P(x > 103)
Calculation the value from standard normal z table, we have,

0.03 is the probability that for the sample mean IQ score is greater than 103.
Answer:
C. 0 < x < 3
Step-by-step explanation:
3<x+3<6
3+−3<x+3+−3<6+−3(Add -3 to all parts)
0<x<3
I hope this helps
