The angle of x is 71°
Because the triangle in isosceles the two bottom angles will have the same measure.
The angles of a triangle will add to 180° so you subtract 38 and divide by 2.
Answer:
B = 3
Step-by-step explanation:
3x + 15 = 4x + 12
= 15-12=4x-3x
= 3 = x
X = 3

Answer:
The mean of samples of 100 IQ scores taken out from this population will have a distribution with mean M=104 and standard deviation s=3.5.
Step-by-step explanation:
We know the population mean and standard deviation, that has a bell-shaped distribution:

The sampling distribution, the distribution of the mean of samples of size n out of this population, will have the same mean as the population mean.

The standard deviation will be related to the population standard deviation and the sample size as:

Then, the mean of samples of 100 IQ scores taken out from this population will have a distribution with mean M=104 and standard deviation s=3.5.
Answer:
Simplifying
5w = 9
Solving
5w = 9
Solving for variable 'w'.
Move all terms containing w to the left, all other terms to the right.
Divide each side by '5'.
w = 1.8
Simplifying
w = 1.8
