The answer is nine because eighteen subtract nine is nine
Answer:
Vertical
Step-by-step explanation:
<2 and <4 are vertical angles they are the angles opposite each other when two lines cross.
The equation for compound interest is:
Where r is the interest rate and n is the number of times per year it's applied. Annually n = 1 and 7% interest r = 0.07 The quarterly rate 2% is already quartered 0.02 = r/n .
You can see that Alexander is incorrect. A quarterly compound interest rate of 2% will accrue more interest than a 7% compound annual interest rate.
1.7% compound quarterly Hope this helps:)
Answer:
The standard deviation of the sample mean differences is _5.23_
Step-by-step explanation:
We have a sample of a population A and a sample of a population B.
For the sample of population A, the standard deviation
is

The sample size
is:
.
For the sample of population B, the standard deviation
is

The sample size
is:
.
Then the standard deviation for the difference of means has the following form:

Finally

We have to find the value of the expression:
( x - y )² ; when x = 5 and y = - 1.
( 5 - ( - 1 ) )² = ( 5 + 1 )² = 6² = 36
Answer: the value is 36.
