Answer:
6.5
Step-by-step explanation:
43.50-24=19.5
19.5/3=6.5
Answer:
Step-by-step explanation:
Given that a confidence interval was constructed using the sample standard deviation, say CI-1.
We then construct a confidence interval with the same numerical values of sample mean, standard deviation, and sample size, but this time assuming the population standard deviation is known, say CI-2.
When population std dev is known we use std error =
For sample std deviation s, we use std error =
When s= sigma, there will not be any difference between these two confidence intervals.
So answer is equal.
Hello!
8u - 8 = -7(u - 1) Given
8u - 8 = -7u + 7 Apply Distributive Property
15u - 8 = 7 Add 7u to both sides
15u = 15 Add 8 to both sides
u = 1 Divide both sides by 15
Answer:
u = 1
Hope this helps!
Answer:
Step-by-step explanation:
First, subtract 180 and "12x-3", which equals 180-12x+3
Then add 46, "5x+7", and "180-12x+3"
46+5x+7+180-12x+3 = 180
Since the degrees in a triangle add up to 180 degrees, cancel out the 180 degrees from this side "180-12x+3" and the other side "180"
46+5x+7-12x+3=0
46+10-7x=0
56=7x
X = 8
Hello!
Point-slope form is
, where m is the slope and (a, b) is a point on the graph.
You are given the slope (
) and a point on the graph (1, -4), so you can just substitute the values into the form, like so:
Simplify:
And that's it!
