Answer 2

Answer:

The probability of selecting a jury with 10 men and 2 women out of out of 29 men and 26 women  is 0.005 (0.5%)

Step-by-step explanation:

Let P(E) denote the probability of choosing a jury with 10 men and 2 women out of 29 men and 26 women.

The sample space for selecting 12 members from the total no of member will be 55c12

The number of ways of selecting 10 men and 2 women is 26c10  29c2.

The probability of event E =  [tex]$=P(E)=\frac{{ }_{20} C_{10} \times{ }_{20} C_{2}}{-C_{12}}$[/tex]

                                                [tex]$=\frac{5,311,735 \times 406}{438,729,741,450}$[/tex] [tex]$=0.005$.[/tex]

Complete question :

Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation. If y varies inversely as the square of x, and y= 1/8 when x=1, find y when x=5

Answer:

k = 1/8

y = 1 / 200

Step-by-step explanation:

Let the constant of variation = k

y varies inversely as the square of x

y α 1/x²

y = k * 1/x²

y = k/x²

y = 1/8 ; x = 1

1/8 = k/1²

1/8 = k

K = 1/8

y ; when x = 5

y = (1/8 ÷ 5²)

y = 1/8 * 1/5²

y = 1/8 * 1/25

y = 1 / 200

We can sue the pythagorean theorem to verify. 15^2+36^2 should equal the longest side squared or 39^2. If we plug in the numbers, it checks out!

Answer:

true

Step-by-step explanation:

we can use the Pythagorean theorem to verify if the sum of the squares built on the legs is equal to the square built on the hypotenuse

36^2 + 15^2 = 39^2

1296 + 225 = 1521

1521 = 1521

the equality is verified so the answer is true

Which statement about this relationship is NOT true?

A.the number of weeks and total number of books increase together at a constant rate.
B.as the number of weeks increases by 1,the total number of books increases by 1.
C.the common difference between the number of weeks and total number of books is 6.
D.doubling the number of weeks also doubles the total number of books.

Answers

Answer:

 

The number of weeks and total number of books increase together at a constant rate.

As the number of weeks increases by 1, the total number of books increases by 1.

The common difference between the number of weeks and total number of books is 6.

Doubling the number of weeks also doubles the total number of books.

Suppose that a certain movie earns $3,000,000 in ticket sales. If 60% goes to the movie and 40% goes to theatres: Movie studios will get $ of the total revenue Theatres will get $ of the total revenue​

Answers

Answer: See explanation

Step-by-step explanation:

Amount earned by movie = $3,000,000.

Percentage that went to movie = 60%

Percentage that went to theater = 40%

Revenue gotten by movie studio = 60% × $3,000,000

= 0.6 × $3,000,000

= $1,800,000

Revenue gotten by theaters = 40% × $3,000,000

= 0.4 × $3,000,000

= $1,200,000

Answer:

X = 4

Step-by-step explanation:

7x + 3 = 31

Step 1: Subtract 3 from both sides.

7x = 28

Step 2: Divide both sides by 7.

7x/7 = 28/7

Therefore, the answer is X = 4

Answer:

D

Step-by-step explanation:

D) The price was increased by 140% and then decreased by 85%.

Answer:

B

Step-by-step explanation:

The price was only increased by 40% because for example, the starting price was 100, then if you increased it by 140% or $140, then the price would be 240.

next, the decreased by 15% and not 85% because 100% - 15% = 85%

The area of a rectangle is 42 m2, and the length is
8 m less than two times the width. Find the
dimensions of the rectangle.

Answers

Answer:

length = 14 m

width = 7 m

Step-by-step explanation:

l = length

w = width

l = 2w - 8

w(2w - 8) = 42

2w² - 8w - 42 = 0

you can factor out a 2 to work with smaller numbers:

w² - 4w - 21 = 0

(w - 7)(w + 3) = 0

w = 7

'w' cannot equal a negative so we discount it as an answer

find length:

l = 2(7) - 8

l = 14 - 8 or 6m
