Answer:
The graph is attached below. Just google it "plot(2(3)^x)"
Step-by-step explanation:
Confidence interval = mean ± margin of error
CI = μ ± ME
The mean is μ = 8.7.
Margin of error = critical value × standard error
ME = CV × SE
At 95% confidence and 9 degrees of freedom, CV = 2.262.
SE = s / √n
SE = 3.3 / √10
SE = 1.04
The margin of error is:
ME = 2.262 × 1.04
ME = 2.36
CI = 8.7 ± 2.36
CI = (6.34, 11.06)
Answer: 31/35

Answer:
Step-by-step explanation:
The best way to start this question is to find the value of the big 3. The big three (on your calculator) are the sin cos and the tangent. Once you have them, the other three are just the reciprocals.
Sin36 = 0.588
Cos36= 0.809
Tan36 = 0.727
============
Now for the other three, which are not on your calculator (directly)
Csc(36) = 1/sin(36) = 1/0.588 = 1.70
Sec(36) = 1/cos(36) = 1/ 0.809 = 1.236
cot(36) = 1/tan(36) = 1/0.727 = 1.376
I don't know if you remember who marries who here. I always remember that cofunction goes with the non cofunction. So the sin and csc are going out together. The cot and tan are dating etc.
