Answer:

x = 6 and DF = 3*6-3 = 15

Step-by-step explanation:

Given triangles are similar and their side lengths are proportional

the similarity ratio for this pair is 4/8 = 1/2

the length of DF:

(7.5)/(3x - 3) = 1/2 cross multiply expressions

3x - 3 = 15 add 3 to both sides

3x = 18 divide both sides by 2

x = 6 and DF = 3*6-3 = 15

Average sales for an online textbook distributor were $67.63 per customer per purchase. Assume the sales are normally distribute

Fynjy0 [20]

Answer:

(a)P(x>85.55)=0.02275

(b) $P(x$

Step-by-step explanation:

We are given that

Average sales for an online textbook distributor per customer per purchase

, $\mu=$ $67.63

Standard deviation of the amount spent on textbooks, $\sigma=$ $8.96

(a) We have to find probability for a randomly selected customer spent more than $85.55 per purchase.

$P(x>85.55)=P(\frac{x-\mu}{\sigma}>\frac{85.55-67.63}{8.96})$

= $P(Z>2)$

= $1-P(Z\leq 2)$

= $1-0.97725$

P(x>85.55)=0.02275

(b)We have to find probability for a randomly selected customer spent less than $76.59 per purchase

$P(x$

$P(x$

-5(x-3+7x=35 what is x

Cloud [144]

Answer:

x=-1/2

Step-by-step explanation:

-5(x-3+7x=35)=-5(x-3+7 x 35=x)

(-5)x+(-5)(-3)+(-5) x 7x=35

-5x+5xx 3-5 x 7x=35

-40x+15=35
