Im doing this question rn and I believe the answer should be C) the ratio of the student body that are in 12th grade and play two or more sports.

Step-by-step explanation: I chose this bc there are 28 12th graders that play 2 or more sports and the total student body is 612. So 28/612 makes most sense to me. Sorry this is so late but I just checked and it’s right!

evablogger [386]

Answer:

Less than 100. Z=83

Step-by-step explanation:

The mean is the average found by adding the sum of the data points and dividing by the number of them. Here there are 3 cars whose speeds are 101, 116, and Z or unknown. The mean of them is 100. Solve for Z.

100 =(101+116+Z)/3

300=217+Z

83=Z

A garage door code has 5 digits. if no digits is repeated, how many codes are possible?
Nataly_w [17]
There are 10 possible digits.

There are 5 position.

So since we cannot repeat same digital, there is 10 possible digits for first position.

We selected one. Now move to second position. We already selected one digit so now there are 9 possible digits. Just select one.

Now move to third position. Again, we already selected another digit so now there are 8 possible digits for third position.

Repeat until you run out of position.

So that would be 10·9·8·7·6 = 30240

There are 30240 possible codes.

Hope this helps.

attashe74 [19]

13) Answer: -3a^3b^2

\left(-6a^2b\right)\left(\frac{1}{2}ab\right)

=-6a^2b\frac{1}{2}ab

=-6a^2b^2\frac{1}{2}a

=-6a^3b^2\frac{1}{2}

=-3a^3b^2

14) Answer: 8y^5x

12y\left(\frac{2}{3}xy^4\right)

=12\cdot \frac{2}{3}xy^{1+4}

=12\cdot \frac{2}{3}xy^5

=\frac{2\cdot \:12xy^5}{3}

=\frac{24y^5x}{3}

=8y^5x
