The probability that the first student is a girl is 5/10.

The probability of the second selection being a boy is 5/9.

(since the first selection was a girl, there are 9 students left) 

The probability that the third student is a girl is 4/8

(there are 4 girls left after one was selected, and 8 students left in total, after the second selection.

The probability is (5/10)(5/9)(4/8)=0.139

A population of insects grows exponentially, as shown in the table. Suppose the increase in population continues at the same rat
Yuki888 [10]

A population of insects grows exponentially, as shown in the table. Suppose the increase in population continues at the same rate.

from the given table

when x=0 , y=20

when x= 1 , y = 30

We use this information to find exponential growth equation

General form of exponential growth is

y=a(b)^x

WE plug in the given values and find out value of a  and b

when x=0 , y=20

20=a(b)^0

20 = a

Now we find out b

when x= 1 , y = 30

30=20(b)^1

divide both sides by 20

\frac{3}{2} = b

So exponential function becomes

y=20(\frac{3}{2})^x

Now we find the insect population at the end of week 11

We plug in 11 for x

y=20(\frac{3}{2})^x

y=20(\frac{3}{2})^11= 1729.951171875

Round the answer to nearest whole number

1730 is the insect population at the end of week 11

Factor 8x+16y+44 i offered up 15 points
belka [17]

Find the Greatest Common Factor (GCF)

GCF = 4

Factor out the GCF. (Write the GCF first, then in parenthesis, divide each term by the GCF.)

4(8x/4 + 16y/4 + 44/4)

Simplify each term in parenthesis

<u>= 4(2x + 4y + 11) </u>
