Answer:

\frac{( \frac{5}{8}  +  \frac{3}{4}) }{(  - \frac{ 2}{3}  -  \frac{5}{6} )}  \\  \\  \\  \frac{( \frac{5}{8}  +  \frac{6}{8}) }{( -  \frac{4}{6} -  \frac{5}{6} ) }  \\  \\  \\  \frac{ (\frac{5 + 6}{8}) }{( \frac{ - 4 - 5}{6} )}  =  \frac{( \frac{11}{8} )}{(  - \frac{9}{6} )}  \\  \\  \\  \frac{11}{8}  \div ( -  \frac{9}{6} ) \\  \\  \\  \frac{11}{8}  \times ( -  \frac{6}{9} ) \\  \\  \\  \frac{11}{8}  \times ( -  \frac{2}{3} ) \\  \\  \\   \frac{11}{4}  \times ( -  \frac{1}{3} ) \\  \\  \\  =  -  \frac{11}{12}  \\  \\  \\  =  - 0.91666

Calculate the slope of a line that passes through the points (3, -20) and (5, 8).
shtirl [24]

Answer:

14

Step-by-step explanation:

Use rise over run, (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(8 + 20) / (5 - 3)

28 / 2

= 14

So, the slope is 14.

Idk wat to do.....<br>........​

Answer:

Mean : 95

Median : 85

Mode : 90

Part B : Impossible

Step-by-step explanation:

We can make an equation to find the mean using the first 5 history test scores.

85=\frac{80+75+90+75+95+n}{6} \\ \\ 85=\frac{415+n}{6} \\ \\ 510=415+n \\ \\ n=95

So a 95 would be needed to have a mean of 85.

Next, the median.

First, we sort the first 5 history scores from least to greatest.

We get 75, 75, 80, 90, 95.

Since, 80 is the middle value, it will be used in the calculation of the median.

We can make an equation with this.

82.5=\frac{80+n}{2} \\ \\ 165=80+n \\ \\ n=85

So a score a 85 would be needed to have a median of 82.5

Thirdly, the mode.

Since 90 is already in the set once, we can just have Maliah score another 90 to make 90 the mode (with the exception of 75 of course).

Finally, Part B.

We can use the equation we had for the first mean calculation but change 85 to 90.

90=\frac{80+75+90+75+95+n}{6} \\ \\ 90=\frac{415+n}{6} \\ \\ 540=415+n \\ \\ n=125

So Maliah would need a score of 125 to make her mean score 90, but since the range is only from 0-100, it is impossible.
