Answer:

Option B

Step-by-step explanation:

Slope of the line is calculated by the formula:

$m=\frac{y_2-y_1}{x_2-x_1}\\\\$

We have the points ( -2 , 4) and (3 , -5) so plug in the values in the formula:

$m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{-5-4}{3-(-2)}\\\\m=\frac{-9}{5}\\$

so the slope(m) equals -9/5

The probability of an event - picking teams. About (a) 10 kids are randomly grouped into an A team with five kids and a B team w

LuckyWell [14K]

Answer: The required probability is $\dfrac{4}{9}$

Step-by-step explanation:

Since we have given that

Number of kids = 10

Number of kids in Team A = 5

Number of kids in Team B = 5

There are three kids in the group, Alex and his two best friends Jose and Carl.

So, number of favourable outcome is given by

$2(\dfrac{8!}{3!\times 5!})$

Total number of outcomes is given by

$\dfrac{10!}{5!\times 5!}$

So, the probability that Alex ends up on the same team with at least one of his two best friends is given by

$\dfrac{2(\dfrac{8!}{5!\times 3!)}}{\dfrac{10!}{5!\times 5!}}\\\\=2\times \dfrac{8!}{3!}\times \dfrac{5!}{10!}\\\\=\dfrac{4}{9}$

Hence, the required probability is $\dfrac{4}{9}$

Three girls bought a pizza for lunch. One girl ate 1/3 of the pizza another girl ate 1/4 of the pizza and the third ate the rest

Bad White [126]

One ate 1/3, Another ate = 1/4.

Total ate = 1/3 + 1/4 = (4 + 3) / 12 = 7/12

Fraction the third girl got = (The whole =1) minus 7/12

= 1 - 7/12 = (12 - 7) / 12 = 5/12

The third girl ate 5/12 of the pizza.
