Matteo was told he could spend AT MOST $80 to spend at the mall. He bought lunch for $25. He wants to buy phone cases for his friends. If the phone cases cost $5. How many phone cases can he buy?
Write and solve the inequality for each word problem

Answers

80 - 25 = 55. 55 divided by 5 = 11 phone cases.
You start with $80 and you buy lunch so you subtract 80-25=55. The phone cases are $5 each. 55 divided by 5= 11 phone cases

Answer:

  6. 15/22

  7. 1/12

  9. 1/16

  10. 0

Step-by-step explanation:

6. 10 of the 12 tiles are "not P", so the probability of a "not P" on the first draw is 10/12 = 5/6. After drawing a "not P" on the first draw, 9 of the remaining tiles are "not P". The probability of drawing one of those is 9/11. So, the joint probability of drawing two "not P" tiles is ...

  (5/6)(9/11) = (5·9)/(6·11) = 15/22

__

7. The probability of drawing a tile worth 3 points is 3/12 = 1/4. The probability of drawing a tile worth 1 point is 4/12 = 1/3. So, the joint probability of drawing a 3-point tile, then a 1-point tile is ...

  (1/4)(1/3) = 1/12

__

9. There are 3 of the 12 tiles worth more than 4 points. The probability of drawing one of them  is 3/12 = 1/4. The probability of doing it again is also 1/4, so the probability of doing it twice is ...

  (1/4)(1/4) = 1/16

__

10. The probability of drawing a Z is 1/12. Having drawn a Z, the probability of drawing a 10-point tile is 0/11. The joint probability of drawing a Z twice is ...

  (1/12)(0/11) = 0

The box plots below show the average gas mileage, in miles per gallon, of the cars sold at a dealership in June and in December.

Gas Mileage of Cars Sold in June
2 box plots. The number line goes from 14 to 34. For cars sold in June, the whiskers range from 21 to 33, and the box ranges from 22 to 29. A line divides the box at 24. For Cars sold in December, the whiskers range from 14 to 26, and the box ranges from 18 to 21. A line divides the box at 19.
Gas Mileage of Cars Sold in December

The manager used the table below to compare the measures of center and the measures of variability.


Median
Range
Interquartile Range
Sold in June
24
33 minus 21 = 12
29 minus 22 = 7
Sold in December
19
26 minus 14 = 12
21 minus 16 = 5

What error did the manager make in the table?

Answers

Answer:

The interquartile range for December should be 21 minus 18 = 3.

Step-by-step explanation:

Hope this helps!

The error which the manager made in the table is that: the interquartile range for December should be 21 minus 18 = 3.

What is a boxplot?

A boxplot is a type of chart that can be used for the graphical representation of a data while showing the five-number summary of a data set with respect to locality, skewness, and spread.

Thus, the five-number summary in a boxplot include the following:

MinimumFirst quartileMedianThird quartileMaximum

Based on the data provided in the table, we can infer and logically deduce that the error which the manager made in the table is that, the interquartile range for December should be 21 - 18 = 3 i.e 21 minus 18 equals to 3.

Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. ... For example, a 50-degree angle and a 40-degree angle are complementary; a 60-degree angle and a 120-degree angle are supplementary.

Solve 4 + x > 6. Graph the solution. A)graph1 B)graph2 C)graph3 D) graph4

Answers

Given the inequality expression 4 + x > 6, we need to solve for x and graph the equivalent graph of the function;

Given

4 + x > 6

Subtract 4 from both sides of the inequality

4 + x - 4 > 6 - 4x > 6 - 4x > 2

Next is to graph the solution x > 2 on the number line.

Since the inequality sign is greater than sign, the line arrow will point towards the right of the number line and the circle will be an open circle.
