Answer:
39% chance for only boys, 61% chance for only girls for the first two questions
the second is a bit trickier,you need a ratio for finding how many would be in 224 groups.
100:224 = 61:x, or 61/100 = x/224
Cross multiply; 100x=13664
Then, divide by 100; x=136.64, or about 137 groups would contain all girls
Step-by-step explanation:
Answer:
39% 61%

The probability of rolling a number less than 3 on a number cube is 2/6. What is the probability of its complement? Simplify your answer.
Answer:
4/6
as we know probability of rolling a number less than 3 on a number cube is 2/6 and then its complement (opposite, greater than 3) that is 4/6
The manager of a dress shop recorded the number of dresses sold during the week, the data is as follows:
17, 15, 16, 20, 15, 19
Find the mean deviation for this data.
Select one:
1.91
2.21
1.67
4.98
Answer: The answer is 1.67
Step-by-step explanation:
First, find the mean by adding all of the numbers and divide them by how many numbers there are, so 17+15+16+20+15+19=102 Then 102/6= 17. Then take the mean and subtract it by every number, and make sure it is the number’s absolute value.
17-17=0, 15-17=2, 16-17=1, 20-17=3, 15-17=2, 19-17=2. Then add all of those numbers and divide them by how many numbers there are. 0+2+1+3+2+2=10. 10/6=1.67
Answer:
1.67
Step-by-step explanation:
[tex]\frac{17 + 15 + 16 + 20 + 15 + 19}{6} = \frac{102}{6} = 17[/tex]

I used the same method with all 6 questions, I had to tweak it slightly for the last 3 as they were mixed fractions.
For the first 3 questions, I used the number you had to make and multiplied it by the denominator. Let's use the first questions as an example.
We need to make 7 by adding something to 27/4. I multiplied 7 by 4 in order to get 28.
This means your goal is to get to 28/4.
The difference between 28/4 and 27/4 is 1/4. Meaning you only have to add 1/4 in order to make 7.
For the last 3 questions I first sorted the fractions out. Let's use the first question again on the right side as an example.
I made 5[tex]\frac{7}{8}[/tex] a top heavy fraction by first multiplying 5 by 8, which makes 40. I then added 40 to 7 making 47. Now the fraction is 47/8.
Now that we have our top-heavy fraction we do the same as last time. We need to make 7. So we multiply 7 by 8 and that makes 56. The difference between 56 and 47 is 9. So we need 9/8 in order to get to 56/8. We need a mixed fraction so 9/8 becomes 1[tex]\frac{1}{8}[/tex].
I hope this helps, if this was confusing don't be afraid to ask questions.

In the elementary school, middle school, and high school, there are 107 teachers altogether. If 27% of the teachers work at the elementary school, 35% work at the middle school, and 38% work at the high school, How many teachers work at the elementary school, how many teachers work at the middle school, and how many teachers work at the high school?
Elementary school:
27% = 207/100 x 27 = 55.89 = 56 teachers
Middle school:
35% = 207/100 x 35 = 72.45 = 72 teachers
High school:
38% = 207/100 x 38 = 78.66 = 79 teachers

Margot splits 8 cups of cereal into 5 equal portions. Three of these expressions give the number of cups in each portion. Which one does NOT?
Answer:
1/8 of 5 is the one that doesn't
Step-by-step explanation:
To figure out the solution you need to somehow divide 8 by 5 so
8/5, 1/5 x 8, 8 divided by 5 are all how you solve the solution.
1/8 of 5 is wrong because you do not need to divide 5 cups of cereal into 8 portions

Pt. 1- Write an algebraic expression that Marshall
can use to determine the total cost of buying
a watermelon that
Watermelons
weighs w pounds and
$0.68 per lo
some tomatoes that
weigh t pounds. How
Tomatoes
$3.25 per lb
much will it cost to
buy a watermelon that
weighs 182 pounds
and 5 pounds of
tomatoes?
Pt. 2 - How much will it all cost?
Answer:
The answer is that the cost will be a total of $142.05. That is $125.80 for Watermelon that weighs 185 lbs and $16.25 for 5 lbs of tomatoes.
Step-by-step explanation:
Given: Watermelons are .68 / lb and tomatoes are 3.25 / lb.
Let w = watermelon weight and tomato weight.
An equation would be:
.68w + 3.25t = Total cost
For 185 lb of Watermelon and 5 lbs of tomatoes:
.68(185) + 3.25(5) =
$125.80 + $16.25 = $142.05
