A correct possibility could be $37.50 because 37.50 x 2 + 4 = 79
Answer:
340 people would renew their membership if the gym had 400 members
The gym's claim is not accurate, because the prediction should be 340 people instead of 330
Step-by-step explanation:
With 400 members, we can predict how many will renew their membership by multiplying 400 by 0.85:
400(0.85)
= 340
So, this would predict that 340 people would renew their membership.
The gym's claim that 330 members would renew their memberships is not accurate, because the correct prediction should be 340 people.
Answer:
h=6
Step-by-step explanation:
To find the volume of a right angle prism-
Find area of cross-section, in this case an isoscles triangle so we know that both of the parallel lines are 3ft
To find the area of the cross-section, do:
3 x 3 = 9
9 ÷ 2 = 4.5 (Area of cross-section)
Since we don't know the length of h, we need do:
27^3 ÷ 4.5 = 6
Therefore 6 is h
Hope I explained it okay:)
The least-square regression line has a slope of:
m=(nΣxy-ΣyΣx)/(nΣx²-ΣxΣx)
and a y-intercept of:
b=(Σy-mΣx)/n
In this case: n=7, Σxy=4899, Σy=391, Σx=85, Σx²=1153 so
m=(7(4899)-391*85)/(7(1153)-85*85))=1058/846
b=(391*846-85*1058)/(7*846)=34408/846
So the line of best fit is:
y=(1058x+34408)/846 and if we approximated this as your answers see to have done....
y=1.25x+40.67
If this is asking for written word then
Twelve times f plus Twenty-four.
