To find the mean of a set of numbers the first thing you do is add all of the numbers together.

7 + (-9) + 6 + (-10) + (-13) + (-5) = -24

After that, you divide the answer you got by how many number there are. (There are 6 numbers).

-24 / 6 = -4

B.-4

Hope this helps!

Reika [66]

Answer:

1/6 cup of bananas = 4/6 cup of apples

1/24 (1/6 ÷ 4 since 4/6 cup of apples is 4 units and we need 1 unit) cup of bananas = 1/6 cup of apples

1 cup of apples = 1/4 (1/24 x 6 for 6 units) cup of bananas

zaharov [31]

Answer:

Step-by-step explanation:

The question is incomplete. The complete question is:

Ten rugby balls are randomly selected from the production line to see if their shape is correct. Over time, the company has found that 89.4% of all their rugby balls have the correct shape. If exactly 6 of the 10 have the right shape, should the company stop the production line?

1)Yes as the probability of six having the correct shape is not unusual

2)NO. as the probability of six having the correct shape is unusual

3)Yes as the probability of six having the correct shape is unusual

4) No. as the probability of six having the correct shape is not unusual

Solution:

If exactly 6 of the 10 have the right shape, it means that the probability of success for the sample is

6/10 = 0.6

Expressing the probability in terms if percentage, it becomes

0.6 × 100 = 60%

Over time, the company has found that 89.4% of all their rugby balls have the correct shape. It means that the probability of success for the population is 89.4%

Comparing both probabilities, the probability of only 6 having the right shape is unusual. Therefore, the correct option is

3)Yes as the probability of six having the correct shape is unusual

Five students go through the lunch line.Each student pays $1.85 for their lunch and gets 3 cookies.The total amount paid is $20.
erastovalidia [21]

Hello there! The cost of a cookie is $0.72.

Start by multiplying the cost of lunch by 5 and subtract that from the total to get rid of the cost of lunch.

$1.85 x 5 = $9.25

$20 - $9.25 = $10.75

So, there were FIVE students and each bough THREE cookies. To find the cost for each cookie, first divide the total spent on cookies by 5 to get what each student spent on cookies, then by 3 to see how much each cookie cost.

$10.75/5 = $2.15

$2.15/3 = 0.716666667, which can be rounded to $0.72.

I hope this helps and have a great rest of your day!
