Answer:
a) TRUE
b) FALSE
c) FALSE
d) TRUE
e) FALSE
Step-by-step explanation:
a)
TRUE because the slope of the correlation line is 2 and this is the rate of change of y respect to x
b)
FALSE
The correlation coefficient r is always between -1 and 1, so it can never be greater than one
c)
FALSE
A student might expect that there is a positive correlation between the age of their laptop and its resale value only if after collecting a large enough sample of data that relates age of the student and price of resale of their laptop, he or she finds that there is a positive correlation coefficient r>0
d)
TRUE
If there is a positive correlation, then the greater the x, the greater the y
e)
FALSE
If there is no correlation between the independent and dependent variables, then the value of the correlation coefficient must be 0.
Answer:
112.065
Step-by-step explanation:
so divide the triangle in two from x to wy
and you get to triangles
then using the first right angled triangle you can apply tan=opposite/adjacent
to get height as 7.56 then apply 1/2bh to get first area as 58.59
first add all angles and subtract from 180=24
then use tan to get the height as 6.9
then apply 1/2bh to get second area as 53.48
then add the two areas to get total
(after getting first one don't multiply by two)
To find the cost of each book, you need to divide the money spent on all of the books by the number of books.
$39 / 10 = $3.90 per book
