There are 30 total students

30/5 = 6

Multiply each number by 6

boys :girls : total

2*6 3*6 5*6

12 18 30

There are 18 girls and 12 boys

18-12 = 6

Answer:

Answer is 6.

Step-by-step explanation:

I will now explain the fastest way to solve this. First off, the ratio is 2:3 so the first thing I do is combine that for 5, then do 30/5 for an answer of 6. Then, I multiply 6 for the ratio, which comes out as 12:18, 12 boys and 18 girls. 18-12=6, so there are 6 more girls than boys in the class.

List 2/3 , 7/12 , and 3/4 from greatest to least thanks .

For this question you should know that:
2/3 = 8/12
and
3/4 = 9/12
so now you can say:
7/12 < 8/12 < 9/12
so:
7/12 < 2/3 < 3/4 :)))
i hope this is helpful

A basketball player makes 80% of her free throws. The random numbers below represent 20 trials for

Taya2010 [7]

Answer:

0.6

Step-by-step explanation:

The numbers 0 to 7 represent a made free throw
The numbers 8 to 9 represent a missed free throw.

Given the simulation data

(8,2) (9,3) (4,0) (5,8) (2,7) (2,0) (5,4) (8,0) (0,4) (9.1)

(9,6) (6,5) (4,4) (1,7) (0,4) (8,5) (8,8) (1,7) (3,5) (0,3)

A pair that contains only numbers between 0 and 7 shows the player makes both throws.

These pairs are:

(4,0) (2,7) (2,0) (5,4) (0,4) (6,5) (4,4) (1,7) (0,4) (1,7) (3,5) (0,3)

There are a total of 12 cases where the player makes both throws.

Therefore:

P(Player makes both throws)=12/20=0.6

The formula for the area of a trapezoid is A=h(b1+b2). Express b1 in terms of A, h, and b2.

lorasvet [3.4K]

In order to find b1 from your formula stated we need to do few calculations
A=hb1+hb2, as you wee I multiply h with both bases( b1 and b2)
I will subtract hb2 from both sides
hb1=A-hb2
now I will divide my new expression by h
b1=(A-hb2)/h
