Answer:

For question 20.

Pamela: y = 20h

y = 20(40)= $800

John: y = 65p

y = 65(11)= $675

And for question 21.

660,000*63%=660,000*0.63=415,800

There are currently 415,800 gallons of water in the pool.

How do i solve 6(2-4y) +4(6y-2)<4(y+4)

netineya [11]

$6(2-4y) +4(6y-2)$ (distribute)

$12-24y+24y-8$ (collect like-terms)

$12-8$ (we flipped the sign because we divided by a negative)

$y>-3$

Brianna is constructing a raised flower bed in the shape of a rectangle. The length of the flower bed is equal to the width plus

inessss [21]

I think the answer is 5 feet because 2(2+5)= 4+10=14. So the missing length is 5 feet.

7x - 2 = 2y 3x = 2y - 1

77julia77 [94]

7x - 2 = 2y
7x = 2y + 2
so
7x = 2y + 2
3x = 2y - 1
----------------subtract
4x = 3
x = 3/4

7x - 2 = 2y
7(3/4) - 2 = 2y
21/4 - 2 = 2y
21/4 - 8/4 = 2y
13/4 = 2y
so
y = 13/4 * 1/2
y = 13/8

answer
(3/4, 13/8)

A class has 35 students, of which 16 are male and 19 are female. If 6 of the students are selected at random to form a committee

madreJ [45]

Answer:

The probability of choosing exactly 2 male and 4 female students = $\frac{\binom{16}{2}\times \binom{19}{4}}{\binom{35}{6}}$

Step-by-step explanation:

We are given that a class has 35 students

Number of male=16

Number of female=19

We have to choose 6 students for committee

We have to find the probability that exactly 2 male students are selected

Probability=P(E)= $\frac{number\;of\;favorable\;cases}{total\;number\;of\;cases}$

If we have to choose total 6 student in which 2 male and 4 female

Combination formula:

$nC_r=\frac{n!}{r!(n-r)!}$

Using the formula

The probability of choosing exactly 2 male and 4 female students = $\frac{\binom{16}{2}\times \binom{19}{4}}{\binom{35}{6}}$
