Find the 2 different rates at which the farm worker worked:

3 pints
--------- = 0.75 pint/min
4 min

2 pints
---------- = 0.67 pint/ min
3 min

Then you need to subtract 0.67 pint/min from 0.75 pint/min to answer this question.

Alternatively, subtract 2/3 pint/min from 3/4 pint/min.

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

Estimate 2.21x5.1 i guess need help please I don’t want to fell this class
Natasha2012 [34]

Answer:

10

Step-by-step explanation:

Im guessing since you have to estimate it then u have to round them up. So if you move both of their points by 2 spaces (divide both by 100) They will be 221x510.

Round them up to 200x500.

That woule be 100 000. Then at the end just dont forget to divide by 10000.

Hope this was helpful

Luke has 1/3 of a package of dried apricots. He divides the dried apricots equally into 3 small bags. Luke gives one of the bags
Nitella [24]
1/3 ÷ 3 = \frac{1}{9} for each

Luke will stay with a total of:

\frac{1}{9} (x 3) = \frac{3}{9}

\frac{3}{9} -  \frac{1}{9} =  \frac{2}{9}

Hope it helped!
