Answer:

Step-by-step explanation:

The formula to find the x coordinate is

$x=\frac{bx_1+ax_2}{a+b}$ where x1 and x2 come from the coordinates of J and K, and a = 2 (from the ratio) and b = 5 (from the ratio). Filling in:

$x=\frac{5(-6)+2(8)}{2+5}=\frac{-30+16}{7}=\frac{-14}{7}=-2$

Your choice is B

Theoretically, if a month is chosen 300 times,

Answer:

75 times.

Step-by-step explanation:

Well there are 12 months and 3 of them start with the letter J, so theoretically, 25% of the months chosen will start with the letter J because $\frac{3}{12}=\frac{1}{4}$ , which is 25%. 25% of 300 (or $\frac{300}{4}$ , for those who like fractions) is 75, so theoretically, we can expect a month that starts with the letter J 75 times.
