Answer:
So the answer for this case would be n=94 rounded up to the nearest integer
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
represent the population standard deviation
n represent the sample size
Solution to the problem
The margin of error is given by this formula:
(a)
And on this case we have that ME =120 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The confidence2 level is 98% or 0.98 then the significance level would be 
and 
, the critical value for this case would be 
, replacing into formula (b) we got:
So the answer for this case would be n=94 rounded up to the nearest integer
Y = 40 + 4m
m = minutes
y = total papers graded
Answer: The cost for the month is $240.
Step-by-step explanation:
Since we have given that
Cost for the two i.e Aveeno and her boyfriend = $40
They were charged 6 times in a month.
As we know that times stands for multiplication.
So, we need to find the cost for the month, where we multiply 6 with $40 to get the amount for the whole month.
So, the amount for the month would be
Hence, the cost for the month is $240.
1)To construct a line parallel to line l and passing through point P our first step is to join the point and line and then draw angles in such a way so that corresponding angles are equal.
Option B is the correct construction of a line parallel to line l and passing through point P.
2) To Construct the perpendicular line to line DE at point F we cut an arc from point F to line DE in such a way it cuts line DE at two points .From these two points we draw arcs which cut each other .
Option C is the correct option to Construct the perpendicular line to line DE at point F.
3) To Construct a perpendicular from the given line segment that passes through the given point we cut two arcs on top and bottom of line segment.
Option B is the right answer.
Multiply 6 and 8 which is 48cm
