Answer:
m=(y2-y1)/(x2-x1)
m=(2-0)/(0-(-2))
m=2/(0+2)
m=2/2
m=1 ==> Gradient of graph
x-int: (-2, 0)
y-int: (0, 2)
Explanation:
m=(y2-y1)/(x2-x1)
m=(2-0)/(0-(-2))
m=2/(0+2)
m=2/2
m=1 ==> Gradient of graph
x-int: (-2, 0) ==> When y=0
y-int: (0, 2) ==> When x=0

As the sample size increases, the t-distribution becomes more similar to the <u>normal</u> distribution.
<u>Option:</u> A
<u>Explanation:</u>
Student t-distribution is any member of a group or family of constant probability distributions that emerge in circumstances where the sample size is limited and the standard deviation of the population is unspecified when calculating the mean of a naturally distributed population.
The z-distribution implies you are conscious of the normal population deviation (never in case) when used for sample means. The t-distribution is focused on using the standard sample deviation as an approximation of the standard deviation in population.
A. The variables in the problem include the miles traveled, the cost to rent the car and the cost per mile traveled in the car.
b. The rate of change in the problem is the amount of payment that is expected per mile traveled.
c.The y-intercept is the total cost of the miles traveled without including the deposit.
d. A straight-line function will work for this problem, where y = mx + c.
m = $0.15, c = $25 and x = total miles traveled.
e. y = ($0.15)(1200) + $25
= $180 + $25
= $205
