34 = 2b+2h
17 = b+h
b = 17-h
30 = b*h
30 = (17-h)h
30 = 17h - h^2
h^2 - 17h + 30 = 0
(h - 15)(h - 2) = 0
h = 2 or h = 15
if h = 2 then b = 30/2 = 15
if h = 15 then b = 30/15 = 2
so one side is 15 long and one side is 2 long
by the way its not a square

Answer: (94.08, 101.92)
Step-by-step explanation:
The confidence interval for unknown population mean is given by :-
, where = Sample mean
= Population standard deviation
z* = Critical z-value.
Given : A random variable x has a Normal distribution with an unknown mean and a standard deviation of 12.
n= 36
Confidence interval = 95%
We know that the critical value for 95% Confidence interval : z*=1.96
Then, the 95% confidence interval for the mean of x will be :-
Hence, the 95% confidence interval for the mean of x is (94.08, 101.92) .

Answer:
Semicircle
Step-by-step explanation:
As we can see, the arc is bounded by the chord MO
since the chord passes through the center of the circle, we have it that the chord is a diameter
Mathematically, an arc bounded by a diameter represents half of a circle
So we can conclude that the arc MNO in circle C is a semicircle
