For number 1, the median is 8
For number 2, the mode is C.100
And for number 3, the mean is D.410
Answer:
1 and 3 are biased
Step-by-step explanation:
A biased sample is ond where all individuals were not given equal likelihood of being selected.
Number 1;
Picking students from the cafeteria would lead to sampling bias because not every student from the school eats from the cafeteria. Those she selected can not be used to account for the whole school. Those that use the cafeteria are only a representation of the whole school and not the entire school.
For number 3:
Paul is interested in finding the mean number of cloth shoppers In a mall and is only collecting data from one clothing store without considering other stores in the mall.
$0.30x=y should be the answer because there is a 30cent fee for every day and x represents how many days it's kept therefore you would add 30 cents for every day it's kept so it's valid to say $0.30x=y becaue the 30 cents times the total of days it's kept = y (the toatl)
<u>ANSWER</u>
The line that is parallel to 
through 
is 
.
<u>EXPLANATION</u>
The equation that is parallel to the line has a slope that is equal to the slope of this line.
By comparing this equation to the general slope intercept form,
,this line has slope 
.
Hence the line parallel to this line also has slope .
Let 
be the equation of the line parallel to the line
We can substitute to obtain;
If the line passes through the point ,then this point must satisfy its equation.
We substitute 
and 
to obtain;
We this equation for 
.
We substitute this value of 
in to to get;
.
Hence the equation of the line that is parallel to through is .
Use the Foil Method:
First: t x t =t^2
Outsides: t x 8 = 8t
Insides: -1 x t = - t
Lasts: 8 x -1 = -8
so you'll have t^2 + 8t - t - 8, simplify it more: t^2 + 7t - 8, A.
