Step-by-step explanation:
Given
A proportional relation is given between minutes spend in reading and no of pages
Suppose we choose the point
, It shows that 2 minutes is taken to read three pages.
Similarly, for point
, It shows four minutes is taken to read 6 pages.
In this way, 6 minutes is taken for 12 pages.
Answer:
the number of coats in the coat check will most likely decrease if the temperatures decrease.
Step-by-step explanation:
Im guessing this answer: Number of coats in the coat check will decrease because the graph shows negative association
But it could also be this answer: Number of coats in the coat check will decrease because the graph shows positive association
I think the graph shows a negative association because when the temperature goes down, the coat check goes down as well
12x - 18 - 4x -2
12x - 4x = 8x (yours 12x - 4x = 8)
-18 - 2 = -20 (yours -18 -1 = 17)
answer:
8x - 20
1.3 bc 8 miss 3 equals 24
Answer:
The value of the test statistic is 
Step-by-step explanation:
Our test statistic is:

In which X is the sample mean,
is the expected value,
is the standard deviation and n is the size of the sample.
The level of ozone normally found is 7.5 parts/million (ppm).
This means that 
The mean of 24 samples is 7.8 ppm with a standard deviation of 0.7.
This means that 
Test Statistic:



The value of the test statistic is
