Out of 50 basketball players trying to make a team, 5 will be chosen. 36 of the 50 are seniors and the remaining players are jun

AveGali [126]

Answer: 5503680

Step-by-step explanation:

The coach wants 2 senior out of 36 so he have

C₃₆,₂ = 36!/( 36 - 2 )! = 36*35*34!/34! = 36 * 35 = 1260

possibilities

Now he also wants 3 juniors out of 14

C₁₄,₃ = 14!/ (14- 3)! = 14*13*12*11!/11! = 14*13*12 = 2184

Now for each pair of senior (from 1260 outcomes) coach has 2184 possiblities therefore

Coach has

2184 * 1260 = 2751840 possibilities to choose from

Again as there are 2 senior to choose for captain we have to multiply by 2 to get the total ways the team could be

2751840*2 = 5503680

7+4(r+3)=9r-6 show work pls AND HELP ASAP

ivanzaharov [21]

$\: \: \: \: \: \:$

$= \: \: \: \: r = 5$

Step-by-step explanation:

$7 + 4(r + 3) = 9r - 6$

distribute 4 through the parentheses

$7 + 4r + 12 = 9r - 6$

add numbers

$19 + 4r = 9r - 6$

move the variable to the left hand side and change its sign

$19 + 9r = - 6$

move the constant to the right hand side and change its sign

$4r - 9 = - 6 - 19$

collect like terms

 $- 5r = - 6 - 19$ 

calculate the difference

$- 5r = - 25$

divide both sides of the equation by -5

 $= \: \: \: \: r = 5$

A line has a y-intercept at (0,−15) and contains the point (−4,−3). What is the equation of the line in slope-intercept form?

nydimaria [60]

Answer: $y=-3x-15$

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" the y-intercept.

Since the given line has a y-intercept at (0,-15), then:

$b=-15$

The formula for calculate the slope is:

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

Knowing that the given line contains the points (0,-15) and (-4,-3), we can calculate the slope. This is:

$m=\frac{-15-(-3)}{0-(-4)}=-3$

Substituting values into $y=mx+b$ , we get that the equation of the line in Slope-Intercept form is:

$y=-3x-15$

statuscvo [17]

Answer:

$\frac{2}{3}$

Step-by-step explanation:

$m=\frac{rise}{run}=\frac{-1+7}{4+5}=\frac{6}{9}=\frac{2}{3}$
