(-2/3)*(-2 1/4)*(3/4) Convert the mixed fraction to improper fraction.
(-2/3)*(-9/4)*(3/4) Then you multiply the numerators with numerators and denominators with denominators
(-2*-9*3) negative times negative is positive, so the negative sign is gone
-------------
(3*4*4*) The lines (-----) is the line of the fraction
54/48 This is the product of this multiplication, now you need to simplify
by reducing the numbers of the fraction
9/8 And that would be the answer
Answer:
The sample size must be approximately 1304.
Step-by-step explanation:
We are given the following in the question:
Population standard deviation = 15,500 miles
We have to construct a 92% confidence interval with margin of error of 1000 miles.
Margin of error =
Putting values, we get,
The sample size must be approximately 1304.
Answer:
didn't give clear instructions on what to do. I just assumed you add them. answer is down below. :)
Step-by-step explanation:
if ur supposed to add them then
1. 1/8 + 8/8 + 3/8 = 12/8 = 1 1/2
2. 1/4 + 2/4 + 1/4 = 4/4 = 1
3. 1/8 + 8/8 + 4/8 = 1 5/8
4. 1/4 + 1/4 + 2/4 = 4/4 = 1
5. 1/4 + 1/4 + 1/4 + 1/4 = 1
Answer: 7
Explanation:
x^2-4x=21
x^2-4x-21=0
(x+3)(x-7)=0
x=-3
x=7
*** if you need to find the positive # only, the ANSWER is 7****
$3,611=$4,000
So $4,000 divided by 6 is 666
