Answer:
y = x - 2
Step-by-step explanation:
The equation of a line can be known as y = mx + b, with m being the slope and b being the y intercept.
1. Find the Slope
The slope can be known as the change in y/change in x.
Two points: (2,0), (0,-2)
-2 - 0/ 0 - 2 = -2/-2 = 1
Slope is 1
So now we can replace the m as 1. So that is y = x + b
2. Find the y intercept
The y intercept is -2 because that is the point where the line meets the y axis.
So our equation is y = x-2
Answer: 0.0062
Step-by-step explanation:
Given : Mean : 
Standard deviation :
Sample size : 
Assume that age of people in the country is normally distributed.
The formula to calculate the z-score :-
For x = 32
The p-value = 
Hence, the the probability that the average age of our sample is at least =0.0062
Answer:
The question is unclear. Please provide the table.
You have to cross multiply the two proportions.
4(54)= 216
9(m)= 9m
then you divide 216 by 9, giving you the answer for m.
216/9= 24
m=24
B is the correct answer, -1.
Isolate the variable by dividing each side by factors that don't contain the variable.
