Answer:
30%
Step-by-step explanation:
28.60-22=6.60
6.60/22=0.3
Answer:
a) Standard error = 0.5
b) 99% Confidence interval: (19.2125,21.7875)
Step-by-step explanation:
We are given the following in the question:
Population mean = 20.50 mpg
Sample standard deviation = 3.00 mpg
Sample size , n = 36
Standard Error =
99% Confidence interval:
Putting the values, we get,
Answer:
first what you do is divide two and then for and then after you divide them together you can get your number so I'm going to show you example how to do it
Step-by-step explanation:
first divide 4 / 2 and then you can get your answer after you divide that
You must follow the steps below:
1. First, you should apply the dstributive property:
=(x²-<span>8x+15/3x)(8x/x-3)
=(8</span>x³-64x²+120x)/3x(x-3)
2. As you can see, the common factor in the numerator is: "8x". So, you have:
=8x(x²-8x+15)/3x(x-3)
3. Then, when you simplify, you obtain:
=8(x²-8x+15)/3(x-3)
Therefore, the solution is: 8(x²-8x+15)/3(x-3)
