First one;
Every 20th person who passes the student centre.
The people passing the student centre are very likely to be students and you're very likely to get a mix of lots of different students producing reliable results.
Answer:
B. Y = 6/4 X
Step-by-step explanation:
Well to find its parallel line we need to put,
2y - 3x = 4 into slope-intercept.
+3x to both sides
2y = 3x + 4
Now we divide everything by 2,
y = 3/2x + 2
So a line that is parallel to the given line will have the same slope but different y intercept, meaning we can cross out choices A and C.

Answer
x= -7, -1
Step-by-step explanation:
x^2= -7x- 8
x^2+ 7x+ 8 =0
x+7=0 x+1=0
x=-7 x=-1
Answer:
y = 5.064 - 0.010x
Here, in this question x = 33
y = 4.734 million views
In this question data is missing and I filled it out and calculated the questions accordingly. Please refer to the attachment for the data calculated.
Step-by-step explanation:
First of all, this question is incomplete. It lacks the data needed to calculate the required things.
So, I figured out the question and I will try my best to solve the question at hand.
I have calculated the some data sheet in excel. Please refer to the attachment for that data.
let a be the salaries
b be the viewers
= ∑
- 
= 7522.8571
= ∑
- 
= 47.1943
= ∑
- 
= -76.8286
Now the slope of the required regression equation is:
Slope =
/
= -76.8286/7522.8571 = -0.010
And the intercept of the required regression equation:
intercept =
x (∑b - slope x ∑a) = 5.064
So, the regression equation will be:
y = intercept + slope x
y = 5.064 - 0.010x
Here, in this question x = 33
y = 5.064 - 0.010 (33)
y = 4.734 million views
Answer:
The answer is D. 18 + (-7)
