She would need to make an 89 on her last test. I hope this helped ^^


What I did is I put a made a list in ascending order (Least to greatest). Next, I added a number starting from 80 and then counted up. I added every number together and divided it by 5 every time I changed the number. Finally I got to the number 89 and it totaled to be 85.

I’m having a hard time with this. Is this a typo by the teacher or should I actually be looking for a size?

Step-by-step explanation:

There are 12 games in the population.  You need to use a random number generator to choose 2 of these games.

RandomSample[{1,2,3,4,5,6,7,8,9,10,11,12},2]

Let's say the first sample you get is {1,5}.  That corresponds to game times of 8 minutes and 7 minutes.  The mean game time for that sample is 7.5 minutes.  So the first row in your table would be:

\left[\begin{array}{ccc}Sample&List\ of\ Game\ Times&Mean\ Game\ Time\\1&8,7&7.5\end{array}\right]

Find the slope of the line that passes through (-1,6) and (15,6)
svp [43]
Slope = \frac{Y2 - Y1}{X2 - X1}
------------------------
6 - 6 = 0
15 - (-1) = 16
0 / 16 = 0
--------------------------------
You have a slope of 0, meaning that this is a straight horizontal line

In ΔOPQ, the measure of ∠Q=90°, PQ = 3.6 feet, and OP = 9.1 feet. Find the measure of ∠P to the nearest tenth of a degree.
svetlana [45]

Step-by-step explanation:

\because \cos \:  \angle P  =  \frac{PQ}{OP}    \\  \\  \therefore \: \cos \:  \angle P  =  \frac{3.6}{9.1}    \\  \\  \therefore \: \cos \:  \angle P  = 0.3956 \\  \\ \therefore \: \cos \:  \angle P  = \cos \: 66.6966 \\  \\  \huge \red{ \boxed{\therefore \:  \angle P  = 66.7 \degree}}
