soldier1979 [14.2K]

Answer:

$\frac{9}{20}$ students.

Step-by-step explanation:

We have been given that of the students that attended Roosevelt Elementary 6/8 of the school play a sport. Of the students are playing a sport 3/5 of the students are also involved in the drama club.

To find the students are both play a sport and a part of the drama club, we need to find 3/5 part of 6/8 as:

$\text{Students who play a sport and a part of the drama club}=\frac{6}{8}\times \frac{3}{5}$

$\text{Students who play a sport and a part of the drama club}=\frac{3}{4}\times \frac{3}{5}$

$\text{Students who play a sport and a part of the drama club}=\frac{3\times 3}{4\times 5}$

$\text{Students who play a sport and a part of the drama club}=\frac{9}{20}$

Therefore, $\frac{9}{20}$ students play sport and part of the drama club.

Abigail and Spencer calculate the slope of the line between the points (3,-1) and (5,4) in different ways. Abigail calculates th

telo118 [61]

Answer:

Spencer and Abigail are correct

Lauren is incorrect

Step-by-step explanation:

Spencer and Abigail are correct

Slope = change in y ÷ change in x

Or $m=\dfrac{y_2-y_1}{x_2-x_1}$

Let $(x_1,y_1)$ = (3, -1)

Let $(x_2,y_2)$ = (5, 4)

$\implies m=\dfrac{4-(-1)}{5-3}=\dfrac52$

This is Spencer's method

Let $(x_1,y_1)$ = (5, 4)

Let $(x_2,y_2)$ = (3, -1)

$\implies m=\dfrac{-1-4}{3-5}=\dfrac52$

This is Abigail's method

It doesn't matter which point you label as point 1 and point 2, as long as you carry out the slope calculation correctly.

Lauren's calculation is wrong as she calculated her slope as:

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

where it should have been $m=\dfrac{y_2-y_1}{x_2-x_1}$
