To find the mean in a set of data you need to add all the numbers and divide by the number of digits.

–6 + 3 + –2 + 6 + 7 + –3 + –5+ 8 = 8

8 divided by 8 because there are 8 numbers which equals 1

So your final answer is <u>1 </u>

Combs and Stratton invested $140,000 and $360,000, respectively, in a partnership. They agreed to share net income in proportion
Phoenix [80]

Answer:

Comb's share will be =  $12,180

Stratton's share will be = $31,320

Step-by-step explanation:

Given:

Comb's investment in the partnership = $140,000

Stratton's investment in the partnership = $360,000

The net income is shared in proportions of their investment.

Net income last year  = $43,500

To find the share of each partner of the net income.

Solution:

Ratio of the investments of Comb to Stratton = \frac{140,000}{360,000}= \frac{14}{36}=\frac{7}{18} (Simplest ratio)

Thus, the investments must be shared in the ratio of 7 : 18

Let Comb's share in dollars be = 7x

Then, Stratton's share in dollars = 18x

Total net income can be given as = 7x+18x=25x

Net income = $43,500

So, we have:

25x=43,500

Dividing both sides by 25.

\frac{25x}{25}=\frac{43,500}{25}

∴ x=1740

So, Comb's share will be = 7\times 1740 = \$12,180

Stratton's share will be = 18\times 1740 = \$31,320

Please help! <br> Use the Law of Cosines to find the values of x and y.
Romashka [77]

Answer:

x = 8.39

y = 55.2

Step-by-step explanation:

9² + 1² - 2(9)(1)cos(50) = x²

x = 8.39

9/sin(y) = x/sin(50)

sin(y) = 0.8215200692

y = 55.23724927
