Answer:

what is a quartile?

Step-by-step explanation:

Answer:

The interquartile range is Q3 minus Q1, so IQR = 6.5 - 3.5 = 3.

Step-by-step explanation:

consider the following numbers: 1, 3, 4, 5, 5, 6, 7, 11. Q1 is the middle value in the first half of the data set. Since there is an even number of data points in the first half of the data set, the middle value is the average of the two middle values; that is, Q1 = (3 + 4)/2 or Q1 = 3.5. Q3 is the middle value in the second half of the data set. Again, since the second half of the data set has an even number of observations, the middle value is the average of the two middle values; that is, Q3 = (6 + 7)/2 or Q3 = 6.5.

Answer:

Step-by-step explanation:

Students at the college are allowed to work on campus no more than 20 hours per week. The jobs that are available pay different rates, starting from $8.75 an hour. Students can earn a maximum of $320 per week.

Write at least two inequalities that could represent the constraints in this situation.

let h = hours worked
let r = the hourly rate in dollars

Answers

H is less than it equal to 20
R is greater than or equal to 8.75

The required system of inequalities is h ≤ 20 and r ≥ 8.75 which represents the constraints in the given situation.

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

College students are allowed to work on campus for no more than 20 hours a week. The listed jobs pay a range of rates beginning at $8.75 per hour. Students can earn up to $320 every week.

Let h represents hours worked

Let r represents the hourly rate in dollars

According to the given situation, the required inequalities would be as:

h ≤ 20 and r ≥ 8.75

Therefore, the required system of inequalities is h ≤ 20 and r ≥ 8.75 which represents the constraints in the given situation.

Gabby bought a backpack and 3 notebooks for $40.66. What is the total tax if the rate is 8%?

Answers

Answer:

It's $3.25 in tax

Step-by-step explanation:

Answer:

$3.24

Step-by-step explanation:

You would first have to figure out the cost of each notebook with tax so you would divide 40.66 by 3

40.66/3 = 13.55

So each notebook costs $13.55 with tax. Now, I multiplied 13.55 by 0.08. I would multiply it by 0.08 because 8% in decimal form is 0.08.

13.55*0.08 = 1.08

I got the answer 1.08. 1.08 is the tax for each notebook so I would multiply it by 3 to figure out the total tax.

1.08*3 = 3.24

Hence, the total tax is $3.24.

Hope this helped :-)
