Answer:

2.987

Step-by-step explanation:

The mean is calculated by dividing the sum of the terms by the # of terms.

For this problem, add all of the terms together:

3.245 + 3.678 + 3.3 + 2.499 + 2.9 + 3.206 + 2.081 = 20.909

Now, divide the product by the number of terms there are. There are 7 terms.

20.909 ÷ 7 = 2.987

Which association best describes the data in the table?
Elodia [21]
Taking the slope about different points, we have
m_{1} = \frac{ y_{2}-  y_{1} }{x_{2}-  x_{1}} = \frac{100-63}{18-12} = \frac{37}{6} =6 \frac{1}{6}  \\ m_{2} = \frac{ y_{2}-  y_{1} }{x_{2}-  x_{1}} = \frac{30-88}{8-16} = \frac{-58}{-8} =7 \frac{1}{4}
The slopes are positive but are not equal, which means that that the association is positive non linear association.

Kira new chatted online with all her friends for 2/3 of a hour on Saturday and 1/4 of an hour on Sunday. She chatted with Penelo
raketka [301]

Answer:

\frac{11}{96} of an hour.

Step-by-step explanation:

Given:

Koran new chatted online with all her friends on Saturday for  = 2/3 of a hour.

Koran new chatted online with all her friends on Sunday for  = 1/4 of an hour.

She chatted with Penelope for = 1/8 of the total time.

Question asked:

Which fraction of an hour did Koran apes chatting with Penelope ?

Solution:

Koran new chatted online with all her friends on Saturday for = \frac{2}{3} of an hour

Koran new chatted online with all her friends on Sunday for = \frac{1}{4} of an hour

Total time of chatting = \frac{2}{3}+ \frac{1}{4}

                                    = \frac{8+3}{12}       ( By taking LCM of 3 and 4 we get 12 )

                                    = \frac{11}{12} of an hour

Now, She chatted with Penelope for = \frac{1}{8}\ of \frac{11}{12} = \frac{1}{8}\ \times \frac{11}{12} =  \frac{11}{96} of an hour

Therefore, Koran chat \frac{11}{96} of an hour with Penelope.

Solve for M. E=cm/r<br> A. M=e+r/c<br> B. M=er/c<br> C. M=e-rc<br> D. M=e+rc
iren2701 [21]
<span>E=<span><span>cm/</span>r</span></span> To solve for m, you have to get it by itself on one side of the equal sign. To do that you have to eliminate c and r and put them at the other side. r is being divided by m, so you have to do the opposite to get it on the other side, which is multiply. Multiplying r to both sides will remove the division, and give you <span>Er=cm</span><span>. So... B is the answer :)</span>

Please answer number six I will give brainliest thank you!
Norma-Jean [14]

Answer:

The new median would be 15.

Step-by-step explanation:

This is because the median means the middle number so we can cross out 2 and 25. Then cross out 6 and 23. Then cross out 7 and 21. Next, cross out 14 and 20. Since there is only one number left, 15, that number is therefore the median.
