Answer: See explanation
Step-by-step explanation:
a. what is Matilda's error?
The error by Maltida was that she mistakenly thought the population was the sample size. In this case, the 900 visitors aren't the sample but the population.
The population is referred Tina's the entire pool where the sample is picked by the researcher.
b. what is the actual sample
The actual sample is 45. The sample is the smaller version which can be gotten from the entire population. It is a subset from the population of 900 visitors. Therefore, based on the question, it is 45.
It’s c I think hope this helped
eeeeeAnswer:
Step-by-step explanation:
I see two lines, a and b, one superimposed on top the other. In such a case, there is an infinite number of solutions.
Answer:y= 2x+7
Step-by-step explanation:
They are all pretty much want you to create the equation so the formula they want is y=mx+b format.
First problem(1,9) slope 2
Y=mx +b
Where y is 9,x is 1 and slope (m) is 2.
Now solve for b using equation
Y=mx +b
9= 2(1)+b
9=2+b
9-2=b
7=b
Now you can create equation
Y= 2x+7
Prob.4
(3,-6) and (-1,2)
First find slope
M= y2-y1/x2-x1
M= 2-(-6)/-1-3
M = 8/-4
M= -2
Your slope "m" is -2
Now do as problem 1 get one of the points and your slope to get equation .
(3,-6) slope -2
Y=mx+b
-6= -2(3)+b
-6= -6+b
-6+6=b
0=b
Y= -2x
Problem 7
(5,13) (10,14)
You solve this one as problem 4 same steps that I did above .
Problem 8 is also the same as steps in problem 4
( 2,160) and ( 2.75,220)
I hope this helps you
