Answer:
$54.25
Step-by-step explanation:
decide 38.75 by 5 to get what each cost then multiply by 7 to get your answer
4y=3x-24
y=3/4x-6
the line intersect x axis in A
y=0, 3/4x=6, 3x=24, x=8 ⇒ A (8,0)
the line intersect y axis in B
x=0, y=-6 ⇒ B (0,- 6)
a.the gradient of l is 3/4
b. AB= V 6^2 +8^2=V36+64=V100=10
According to the Central Limit Theorem the sum or average of at least 30 independent random variables with the same distribution is approximately normal. Therefore the answer is 'at least 30 measurements.'
58 because 80 times 15 percent is 12. so you subtract 12 from 80 that gives you 68 then you subtract the coupon which is 10 dollars. you total is 58.
6. The formula for slope is y=mx+b. Your B is 3, and your M is 6. B= Y intercept and M=Slope
