B. 5 shirts were bought and the total was $110
C. 4
Step-by-step explanation:
A.
For every 1 increase in the x variable(the first number) the y variable(the second number) increases by 22
B.
The pair represents that he got 5 shirts and that he paid $110. you can check your work by seeing that if yoiu divide 110 by 5 you get the price of the t-shirt; $22
C.
If each shirt is $22 you divide $88 by $22 and get the amount of t-shirts bought; 4
What's the slope of the line that passes through the points (4,8) and (2,12)? Write your answer in simplest form
The slope of the line passing through the given points (4, 8) and (2, 12) is -2.
Given the following points:
Points on the x-axis = (4, 2).Points on the y-axis = (8, 12)To find the slope of the line passing through the given points (4, 8) and (2, 12):
The slope of a line is simply the gradient of a line and it describes both the direction and steepness of an equation of a straight line.
Mathematically, the slope of a line is given by the following formula;
[tex]Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substituting the given points into the formula, we have;
[tex]Slope. \;m = \frac{12 \;- \;8}{2\; - \;4}\\\\Slope. \;m = \frac{4}{-2}[/tex]
Slope, m = -2.
Therefore, the slope of the line passing through the given points is -2.

- 2x – 5 < 12
Yo help
Answer:
x > -17/2
Step-by-step explanation:
Step 1: Write inequality
-2x - 5 < 12
Step 2: Solve for x
Add 5 to both sides: -2x < 17
Divide both sides by -2: x > -17/2
Here, we can see that any number greater than -17/2 would work, so x could equal 01234718905731857013570 if we wanted it to, as long as it is greater than -8.5.

In a group of students, each student is taking a mathematics course or acomputer science course or both. One-fifth of those taking a mathematics course arealso taking a computer science course, and one-seventh of those taking a computerscience course are also taking a mathematics course. What percentage of the studentsare taking a mathematics course
Answer:
63.64%
Step-by-step explanation:
Let P(M) be the percentage of students enrolled in a mathematics course
Let P(C) be the percentage of students enrolled in a Computer Science (CS) course.
We are told that One-fifth of those taking a mathematics course arealso taking a computer science course.
Thus, we can write that as:
P(M|C) = 1/5,
We are also told that one-seventh of those taking a computer science course are also taking a mathematics course.
Thus, we can write it as;
P(C|M) = 1/7
According to sets notations, P(M ∩ C) will be the probability that any student is enrolled in both Maths and Computer Science.
Thus;
P(M ∩ C) = P(M|C)P(C) = (1/5)P(C)
Also,
P(M ∩ C) = P(C|M)P(M) = (1/7)P(M)
Equating them, we have;
(1/5)P(C) = (1/7)P(M)
P(C) = (5/7)P(M)
Now; P(M U C) = 1
Let's express out P(M U C)
P(M U C) = P(M) + P(C) - P(M ∩ C) = P(M) + (5/7)P(M) - (1/7)P(M) = (11/7)P(M)
1 = (11/7)P(M)
P(M) = 7/11 = 0.6364 or 63.64%

Answer:
y=120 degree z=120 degree and x=60degree
Step-by-step explanation:
y+60¤ =180¤(being straight line )
or,y=180¤-60¤
or,y=120¤
therefore y=120¤
Now z= 120¤ (being corresponding angle)
therefore z =120¤
here at last,
z+120=180 (being straight anngle)
or, z=60¤
therefore z =60¤
( ¤): degree

Answer:
The cost must be $32 since that is the only cost possible for the 1st deal
Step-by-step explanation:
Let C represent the total cost of each deal
Let T be the number of trips down the water slide
C = 32 for the 1st deal since the cost is the same regardless of how much she rides
C = 18 + T for the 2nd deal
To find when the two costs are equal set them equal to each other and solve for T
32 = 18 + T
T = 14 trips
The cost must be $32 since that is the only cost possible for the 1st deal

2. Suppose that P(A) = 0.32, P(B) = 0.46, P(C) = 0.23, P(A ∪ B) = 0.57, P(A ∪ C) = 0.55, P(B ∪ C) = 0.49. a. Compute P(B ′ ). b. Compute P(A ∩ B), and use the result to determine if A and B are mutually exclusive. c. Determine if A and C are mutually exclusive. Explain briefly. d. Describe in simple words what (A ∪ B ∪ C)′ represents. Determine P[(A ∪ B ∪ C)′]. (Hint: Determine first P(B ∩ C).)
Answer:
Step-by-step explanation:
From the given information:
a.
Compute [tex]P(B')[/tex]:
[tex]P(B') = 1 - P(B) \\ \\P(B') = 1 - 0.46 \\ \\ P(B') = \mathbf{0.54}[/tex]
b.
Compute P(A ∩ B)
P(A ∩ B) = P(A) +P(B) - P(A∪B)
P(A ∩ B) = 0.32 + 0.46 - 0.57
P(A ∩ B) = 0.21
Thus, since P(A ∩ B) ≠ 0, we can say that they are not mutually exclusive.
c.
P(A ∩ C) = P(A) +P(C) - P(A∪C)
P(A ∩ C) = 0.32 + 0.23 -0.55
P(A ∩ C) = 0
Thus, since P(A ∩ C) = 0, we can say that they are both mutually exclusive.
d. To determine P[(A ∪ B ∪ C)′]
i.e. none of the events occurring
Then :
P(B ∩ C) = 0.46 +0.23 -0.49
P(B ∩ C) = 0.20
Therefore:
P(A ∪ B ∪ C) = P(A) + P(B) + P(C) - P(A ∩ B ) - P(A ∩ C) - P(B ∩ C) + P(A ∩ B ∩ C)
P(A ∪ B ∪ C) = 0.32 + 0.46 + 0.23 - 0.21 - 0 - 0.20 + 0
P(A ∪ B ∪ C) = 0.60

Sarah the cheetah ran 100 meters at a speed of 16.8 meters per second. An olympian ran the 100-meter dash in 9.6 seconds. How much faster was Sarah the cheetah’s speed, to the nearest tenth of a meter per second? 0.9 meters per second 1.6 meters per second 6.4 meters per second 10.4 meters per second
Answer:
Sara's speed was 6.4 meters per second faster
Step-by-step explanation:
(Were going to name the olympian steve)
First, we have to find how many meters per second Steve ran. To find this we must divide the number of meters he ran by the amount of time it took him to run all 100 meters.
100 ÷ 9.6 =10.41666667
Since the problem tells us to round to the nearest tenth of a second we round 10.41666667 to 10.4. So now we know how many meters per second Steve ran. Now all we have to do is subtract the number of meters per second Sarah ran, from the number of meters per second Steve ran.
Sarah- 16.8 meters per second
Steve- 10.4 meters per second
16.8-10.4= 6.4
And there you have it! Sarah ran 6.4 meters per second more than Steve. I hope this answer was accurate and helpful. I hope you have an AMAZING day!
