Answer:
Step-by-step explanation:
divide y by x
in a table and coordinate pair, which is something like (0,4), x always comes first. So, in this table x is the time in seconds and y is the distance in meters. 120/4=30 meters per second. For the second part of the table, since we know what the slope is, or the constant rate of change, 30, we can multiply 30 by 25 which is 750. You can also use the equation y=mx, m is the slope, and x is a point on the coordinate pair. For example, in the second table, y=30(25). For the last part of the table, you can use the same equation. 270=30x. We try to get x alone so we do, 270 divided by 30 which is 9. So a cheetah runs at 270 meters per 9 seconds.

You need to include more information.
Step-by-step explanation:
Answer:
24 for 5 is higher because you have to divide 24 by 5 and if you do that it gives you $4.8, while 5 for 24 gives you a unit rate of $0.20.
Answer: 37
Step-by-step explanation:
Given : Significance level : 
Critical value : 
margin of error : E= 1 mile per gallon
Population standard deviation: 
miles per gallon.
We know that when the population standard deviation is known then the formula to find the sample size is given by :
[Round to the next whole number.]
Hence, the required number of automobiles should be used in the test = 37
