Answer 1

Answer: The coach can select the captain in 20 ways (i.e. from all the available 20 players), and he can select the co-captain in 19 ways (i.e. after selecting the captain, there will be 19 people left).
Therefore, the coach can select the captain and the co-captain in 20 x 19 = 380 ways.

Answer 2

Answer:

Answer:

Step-by-step explanation:

1. Number of peoples available to choose from = 20

$\text{Ways of selecting the captain from 20 people = }_(1)^(20)\textrm {C}=20$

After selecting the captain number of people left among which co captain can be selected = 20 - 1 = 19

$\text{Ways of selecting the co captain from 19 people = }_(1)^(19)\textrm {C}=19$

Hence, Number of ways a coach select the captain and co-captain of a team from a group of 20 people = 20 × 19 = 380

Therefore, The correct option is C. 380

2. Total number of players = 7

Number of players to be selected = 5

$\text{So, number of ways of selecting 5 players out of 7 = }_(5)^(7)\textrm {C}=21$

Therefore, The correct option is A. 21

3. Total number of outcomes = 20

The digits 1, 2, 3, 4, 5, 6 represent the student who make a C

Number of students who make a C at least 3 times = 13

$\bf\textbf{Required Probability = }(13)/(20)$

Therefore, The correct option is D

Take the overall height and divide by the number of years. This will give you feet per year:

150 ft / 15 years = 10 ft per year

Proof:

15 * 10 = 150

150 = 150

-4y+ 5x= 17
The point (x, -3) is a solution to the equation shown. What is the value of x?

Answers

Answer:

x = 1

Step-by-step explanation:

Given

- 4y + 5x = 17 and (x - 3) is a solution

Substitute y = - 3 into the equation and solve for x

- 4(- 3) + 5x = 17

12 + 5x = 17 ( subtract 12 from both sides )

5x = 5 ( divide both sides by 5 )

x = 1

Solution is (1, - 3 )

Answer:

x = 1
