Answer:

Part A: A

Part B: x+18=8(2x-6)-18x

Step-by-step explanation:

When in Step 1, the equation is multiplied by two, the second term, -9x, is not doubled as well. Thus the answer above for Part B, is what Step 1 should look like.

Finishing evaluating the problem:

x+18=16x-48-18x

x+18=-2x-48

3x=-66

x=-22

Step-by-step explanation:

Separate each layer.

Area1+Area2= Total area

A1= a*b*d

A2=a*c*d

A1=5*5*3=75 in^2

A2=5*10*3=150 in^2

75+150=225 in^2

A pharmacist receives a shipment of 22 bottles of a drug and has 3 of the bottles tested. If 5 of the 22 bottles are contaminate
Norma-Jean [14]

Answer:

There is a 44.16% probability that exactly 1 of the tested bottles is contaminated.

Step-by-step explanation:

C_{n,x} is the number of different combinatios of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

In this problem, we have that:

Total number of combinations:

C_{22,3} = \frac{22!}{3!(18)!} = 1540

Desired combinations:

It is 1 one 5(contamined) and 2 of 17(non contamined). So:

C_{5,1}*C_{17,2} = 5*17*8 = 680

What is the probability that exactly 1 of the tested bottles is contaminated?

P = \frac{680}{1540} = 0.4416

There is a 44.16% probability that exactly 1 of the tested bottles is contaminated.

Korvikt [17]
You’ll need a total of 86x6= or 516 total points to meet your average of at least 86. Now subtract out your current scores: 516- 75-93-90-82-85 = 91. You’ll need 91 to meet the 516 total requirement.

Kesley is thinking of a number. She says that it’s the sum of a number and nine. Multiplied by 2/3, is equal to -18.
Aliun [14]

Answer:

Only the firsts and fourth choices (\frac{2}{3}(x+9)=-18 and \frac{2}{3}x+6=-18)

Step-by-step explanation:

Turn the equation into words:

"A number plus 9"

(x+9)

"Multiplied by \frac{2}{3}"

\frac{2}{3} (x+9)

"Is equals to -18"

\frac{2}{3}(x+9)=-18

Distribute to find the second equation:

\frac{2}{3}(x+9)=-18\\\frac{2}{3}x+6=-18
