You have been cleaning this diesel dispenser for 35 minutes you have completed 6 dispensers how many minutes has it taken you to

bearhunter [10]

1. c. 5.83

35 minutes divided by 6 dispensers = 35/6 or 5.83 approximately

2. d. 1 quart

There are 4 quarts in a gallon. If 1 quart is cleaning solution then the other 3 would be water.

3. d. 14

150 times 2 = 300, so you are using 2 cases per day. 2 times 7 days = 14 cases. ? That might help :)

A factory worker conducted a test on a random sample of 150 products. I love the products tested, 2 were found to have defects.

VikaD [51]

So what you would do is 3000 divided by 150 which is 20 then you would multiply 20 by 2 which is 40 so 40 is most likely defective.

A computer company produces an extremely light laptop and they claim it is the lightest on the market weighing only 32 ounces. t

Darina [25.2K]

Solution: We are given:

$\mu=0.33, \sigma =0.7$

Let $x$ be the weight (oz) of laptop

We have to find $P(x>32)$

To find the this probability, we need to find the z score value.

The z score is given below:

$z=\frac{x-\mu}{\sigma}$

$=\frac{32-33}{0.7}$

$=-1.43$

Now, we have to find $P(z>-1.43)$

Using the standard normal table, we have:

$P(z>-1.43)=0.9236$

0.9236 or 92.36% of laptops are overweight
