Answer: a) 27.5, b) 5.33.
Step-by-step explanation:
Since we have given that
and n = 180
We need to calculate the sample mean and sample standard deviation.
So, the mean of the distribution of sample means is
The standard deviation of the distribution of sample means is
Hence, a) 27.5, b) 5.33.

Answer:
a2+b2=c2
Step-by-step explanation:
A right triangle is a triangle in which one of the angles is a 90∘ angle. A triangle can be determined to be a right triangle if the side lengths are known. If the lengths satisfy the Pythagorean Theorem (a2+b2=c2) then it is a right triangle.

Answer:
x=23, y=157
Step-by-step explanation:
23 and x are on equalivent sides of the rhombus so they are equal. To solve for y you have to multiple 23 by 2. Getting 46 you subtract that from 360 to get 314. Dividing 314/2 you get 157.
