2. 7 + 2
Step-by-step explanation:
1. If we look at the model, there are 5 positive circles and 2 negative circles. This means that we can write it in :-
5 + (-2) 5 - 23 --> *5 - 2 = 3*2. It asked for an equivalent to 7 - (-2). Remember that negative and negative would be positive. So, it would become 7 + 2.

The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 31 hours and the median is 27.2 hours. Twenty-four of the families in the sample turned on the television for 16 hours or less for the week. The 7th percentile of the data is 16 hours.
Step 1 of 5: Based on the given information, determine if the following statement is true or false. The 54th percentile is less than 26 hours.
Step 2 of 5: Approximately how many families are in the sample? Round your answer to the nearest integer.
Step 3 of 5: Based on the given information, determine if the following statement is true or false. Approximately 200 families turned on their televisions for less than 35 hours.
Step 4 of 5: What is the value of the 50th percentile?
Step 5 of 5: Based on the given information, determine if the following statement is true or false.The first quartile is greater than or equal to 20 hours.
Answers
Answer:
Step-by-step explanation:
The mean of the data is 31 hours and the median of the data 27.2 hours.
24 of the families in the sample turned on the television for less than 16 hours for the week.
The 7th percentile = 16 hours
Step 1:
The median is a value that divides the whole data into two equal parts. It implies that the median represents the 50th percentile of the data.
Given that the median is 27.2 hours, thus the 54th percentile should be greater than 27.2 hours.
Thus, the given statement is false.
Step 2:
Let assume that N is the total number of families
24 of the families in the sample turned on the television for less than 16 hours for the week.
The 7th percentile = 16 hours
It means that 7% of N = 24
N = 24/0.07
N = 343
Step 3:
From (2), N = 343
Given that median= 27.2 hours.
It means 200 families turned on their television for less than 27.2 hours.
We don't know if this is true for 35 hours. 100 families may use less than 35 hours and 200 may use more than 35 or vice versa. In addition to that, even 50 families might use less than 35 and 350 may use more than 35 hours.
Hence, the statement is false.
Step 4:
The median is the 50th percentile value which is = 27.2 hours
Step 5:
The statement is false
The 25th percentile is the first quarter of the data and if the 7th percentile is 16 hours, then the 25th percentile should be greater than that.

Answers
Answer:
I need help with that too
Step-by-step explanation:
The first quartile of this data will be 28. The mean of the first quartile is different from the median of the total data set.
How do you find the data's mean and median?The mean is the proportion of the total number of observations to the sum of the observations.
The median is a number for an organized data set (in ascending or descending order) that has the same number of observations to its left and right.
To get the first quartile, use the following formula:
16, 28, 28, 32, 21, 18, 35
Arrange data;
16,18,21,28,28,32,35
The first quartile's median is the first quartile, and the third quartile's median is the third quartile.
16, 28, 28
Median=28

Steve already has 5 flowers in his garden, and he can also grow 1 flower with every seed packet he uses. Write an equation that shows the relationship between the number of seed packets x and the total number of flowers y.
Answers
Answer:
y = x + 5
Step-by-step explanation:
Using the information provided we can create the following equation. Since every seed packet can grow 1 single flower we would need to multiply 1 by the number of seed packets (x), which simplified would be just x . Next we are told that Steve already has 5 flowers in his possession meaning we need to add this to the new flowers that he is growing to get the total number of flowers.
y = x + 5

membership = 20
book cost = 3 x number of books
t = 20 + 3b
Answer:
The answer would be 3b + 20 = t
Step-by-step explanation:
I think the question is referring to the total cost per month to be a member.
Since it costs 20$ monthly no matter what, that price will always stay the same per month.
However, it also costs $3 per book purchased. This price may not always stay the same, because you could buy a different number of books each month, and the price would be different. The cost for books depends on the number of books you buy, which is not stated in the question.
That is why you replace the number of books with a variable, in this case b.
So the equation would be 3b + 20 = t , with 3 being the cost per book, b being the number of books, 20 being the monthly cost, and t being the total amount per month.

4 times, he bought dinner 4 times
Step-by-step explanation:
if kevin get paid for 3 hours, then you would multiply $14 by 3. you would end up with $42, then the weekly allowance is $21. then by adding $21 to the $42 we have you would get $63. then a bus ride costs $2.50 and since he rode it 6 times you would multiply $2.50 by 6, which would equal $15. Then subtracting $15 from the $63, you would end up with $48, and then by dividing the total amount for the dinner each time bought, so $12/$48 would equal to 4 times.

Curtis is buying a home, it’s mortgage loan is 360,000 at 4.3 percent interest for 30 years making 12 payments a year one per month. Find C,N,L and P, Her monthly payment? Make sure to write the formula
Answers
Answer:
The monthly payments during the term of the loan will be $1,043.
Step-by-step explanation:
Given that Curtis is buying a home, and it's mortgage loan is 360,000 at 4.3 percent interest for 30 years, making 12 payments a year one per month, to determine her monthly payment the following calculation has to be done:
360,000 x 0.043 = 15,480
15,480 + 360,000 = 375,480
375,480 / (12 x 30) = X
375,480 / 360 = X
1.043 = X
Thus, the monthly payments during the term of the loan will be $ 1,043.
