Answer:
The standard deviation of the sampling distribution of sample means would be 0.8186.
Step-by-step explanation:
We are given that
Mean of population=23.2 pounds
Standard deviation of population=6.6 pounds
n=65
We have to find the standard deviation of the sampling distribution of sample means.
We know that standard deviation of the sampling distribution of sample means
=
Using the formula
The standard deviation of the sampling distribution of sample means
=
Hence, the standard deviation of the sampling distribution of sample means would be 0.8186.
Area of triangle = 1/2 x base x height
Let the base be "b"
90 = 1/2 x 10 x b
90 = 5b
b = 18 ft
Base = 18 ft
Solution,
-28x^2+35x
take the common,
-7x(4x-5)
The answer is -7x(4x-5)
Here,
If we solve,
-7x(4x-5)
Then, the answer would be:
= -7x*4x+7x*5
= -28x^2+35x
Hope it helps
Good luck on your assignment
Exponential increase
150,000x(1.08)^x where x is years
150,000x(1.08)^3 = 188957
Every foot is composed of 12 inches. Below is the way to solve the number of inches (n) in 12 ft.
n = (12 ft) x (12 inches / 1 ft) = 144 inches
To determine the number of 2-inch segments, divide 144 inches by 2. The division gives an answer of 72. Thus, there are 72 2-inch segment in 12 ft.
