A family has 8 girls and 4 boys. A total of 2 children must be chosen to speak on the behalf of the family at a local benefit. What is the probability that 1 girl and 1 boy will be chosen?A. 2/11
B. 1/6
C. 2/33
D. 16/33

Answers

Answer 1
Answer: Probability is all about multiplying fractions.

The first fraction is the probability of picking a girl.. so how many of the 12 total children are girls. (8/12)

The second fraction is the probability of picking a boy.. so how many of the 11 remaining children are boys. (4/11) 

8/12 X 4/11 = 8/33 -> this isn't even an option but I'm like 10000% this is the right answer.. 

I started off this answer feeling so confident lol. good luck.
Answer 2
Answer: D. 16/33

because there are 28 g/g pairs, 6 b/b pairs, and 32 g/b pairs. In total 66 pairs, and of those pairs 32/66 are 1 girl and 1 boy, reduced is 16/33.

Changing a fraction to its decimal form can be done by long division method. Dividing the denominator by its numerator will change the fraction into decimal form. Alternatively, you can use a calculator to do that for you. Below are the fractions with their decimal forms listed:

1.) 2/5 = 0.4 (D)
2.) 7/20 = 0.35 (A)
3.) 3/25 = 0.12 (C)
4.) 7/10 = 0.7 (B)

This questions is breaking my head... If a gumball is randomly chosen from a bag that containsexactly 6 yellow gumballs, 5 green gumballs, and 4red gumballs, what is the probability that the gumballchosen is NOT green? Can you also write ratio for me to this question?

Answers

Total gumballs= 6 yellow+ 5 green + 4 red
                     = 15 gumballs
Green gumballs=5
Other gumballs= 15-5= 10
Probability= Other non-green gumballs/Total gumballs
               =10/15 = 2/3
Probability of not getting green gumball is 2/3 or 66.66666.... %
The ration is 2:3.

Question is: Solve -7(x+6)=4(x+6)

Answers

\huge\boxed{x=-6}

Hey there! Our goal here is to isolate the variable on one side of the equation.

\begin{aligned}-7(x+6)&=4(x+6)&&\smash{\Big|}&&\textsf{Start with the original equation.}\n-7x+(-7)(6)&=4x+4(6)&&\smash{\Big|}&&\textsf{Distribute.}\n-7x-42&=4x+24&&\smash{\Big|}&&\textsf{Multiply.}\n-7x-4x&=24+42&&\smash{\Big|}&&\textsf{Move the terms.}\n-11x&=66&&\smash{\Big|}&&\textsf{Combine like terms.}\nx&=\boxed{-6}&&\smash{\Big|}&&\textsf{Divide both sides by $-11$.}\end{aligned}

Answer: The answer is x=–6.

Step-by-step explanation: Step 1: Simplify both sides of the equation:

(-7)(x)+(-7)(6)=(4)(x)+(4 )(6) (Distributive Property)

-7x+-42=4x+24

-7x-42=4x+24

Step 2: Subtract 4x by the both sides: -7x-42-4x=4x+24-4x

-11x-42=24

Step 3: Add 42 to the both sides: -11x-42+42=24+42

-11x=66

And step 4: Divide both sides by -11: (-11x)/(-11)=(66)/(-11), x=-6.

Susan drove at an average speed of 30 miles per hour for the first 30 miles of a trip and then at an average speed of 60 miles per hour for the remaining 30 miles of the trip. if she made no stops during the trip, what was susan's average speed, in miles per hour, for the entire trip?

Answers

The average speed is given by:
average speed=(total distance)/(total time)
total time for the first 30 miles was:
time=distance/speed
=30/30
=1 hr
total time for the remaining 30 miles
=30/60
=0.5
hence the average speed will be:
speed=(30+30)/(1+0.5)=60/1.5=40 miles per hour
