Several million lottery tickets are sold, and 21% of the tickets are held by men. Suppose you select a random sample of people and let X represent the number of people in your sample for which are men with winning tickets. What type of random variable is X?


hypergeometric

Bernoulli

poisson

uniform

Answers

Answer 1

Answer:

hypergeometric

Step-by-step explanation:

For each winning ticket, there are only two possible outcomes. Either it is held by a men, or it is not.

There is a set number of X, and as the number of winning tickets decrease, the probability of a winning ticket being held by a men can decrease or increase. This is a characteristic of the hypergeometric distribution.

Answer:

1) 4

2) 5

3) -23

4) 8

5) 7

6) -64

7) -10

8) 19

9) 9

10) -56

Answer:

1) = -4

2) = 5

3) = 17

4) = 8

5) = 7

6) = -64

7) = -10

8) = 19

9) = 9

10) = -56

Step-by-step explanation:

1) (-4 + 2)^2 = -2^2 = -4

2) 25 / (9 - 4) = 25 / 5 = 5

3) 4 * 5 - 3 = 20 - 3 = 17

4) 2(2 + 2) = 2 * 4 = 8

5) (-10 + 5) / 5 + 8 = -5 / 5 + 8 = -1 + 8 = 7

6) (-3 - 1)^3 = -4^3 = -64

7) 5(5 - 7) = 5 * -2 = -10

8) 2 * 7 + 5 = 14 + 5 = 19

9) (5 * 3 + 3) / 2 = (15 + 3) / 2 = 18 / 2 = 9

10) 8(-1 - 6) = 8 * -7 = -56

1) James deposited $4,000 into an account. He made
no additional deposits or withdrawals. James earned
5.75% annual simple interest on the money in the
account.
What was the balance in dollars and cents in James
account at the end of 5 years?

Answers

Answer:

$5150

Step-by-step explanation:

Given data

Principal=$4000

Rate=5.75%

Time= 5 years

The expression for the balance on  simple interest is

A=P(1+rt)

substitute

A=4000(1+0.0575*5)

A=4000(1+0.2875)

A=4000X(1.2875)

A=$5150

Hence the  balance is $5150

Dilate Point B by a scale factor of 1/2

Answers

Answer:

( -1.5 , 1 )

Step-by-step explanation:

Hello There!

When dilating a point we divide or multiply the coordinates by whatever the scale factor is

Because the scale factor is 1/2 we just have to divide the coordinates of point B by 2

Preimage coordinates - ( -3 , 2 )

-3/2=-1.5 or -3/5

2/2=1

Dilated image coordinates ( -1.5 , 1 )

A train travels 5 miles in 12 minutes at this rate how far will go in two hours

Answers

Answer:

Well, 60 (minutes in an hour) divided by 12 (from the problem) is 5, so you have to multiply that 5 by the 5 from the problem to find that the train is going 25 (5*5) mph. Just double this for two hours, and you result in 50!

{45x+6y=15-x+18y=11 is..........................

Answers

Answer:

Step-by-step explanation:

45x+6y=15

-x+18y = 11

let's use elimination, the other way is by substitution,  either way works but, it looks to me like elimination would be easy with the  'y'

3(45x+6y=15)

135x + 18y = 45 ( subtract  2nd eq.  from 1st )

-( -x+18y = 11 )

136x +0y =34

x = 34 /136

x = 1 /4

there is X

plug that back into either of the 1st or 2nd equations to solve for y

- 1/4 + 18 y = 11

18y = 11 1/4

18y = 45/4

y = 45/4 *  1/18

y = 45/ 72

the fractions seem  "difficult"  but that's just what the given problem finds
