Tiana was designing a fish tank that could hold 5,364 ml of water. She's already filled the tank a quarter of the way. How many

gavmur [86]

Answer: 4.023 litres

Step-by-step explanation:

Find out what a quarter of the capacity of the tank is first:

= 5,364 * 1/4

= 1,341 ml

The number of ml left to fill up the tank is:

= 5,364 - 1,341

= 4,023 ml

1 litre = 1,000 ml

4,023 ml in litres = 4,023 / 1,000

= 4.023 litres

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

$P(x$

$P(x$
