What's the slope of the line that passes through the points (4,8) and (2,12)? Write your answer in simplest form
Answers
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.

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¤

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

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
Answers
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!
Answer:
C
Step-by-step explanation:
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).)
Answers
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

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
Answers
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%

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.

Two cards are selected from a standard deck of 52 playing cards. The first card is not replaced before the second card is selected. Find the probability of selecting a six and then selecting a nine.
The probability of selecting a six and then selecting a nine is
(Round to three decimal places as needed.)
Answers
Answer:
0.006
Step-by-step explanation:
The probability that the first card is a six is 4/52.
There's one less card now, so the probability that the second card is nine is 4/51.
The total probability is:
P = (4/52) (4/51)
P ≈ 0.006
If Two cards are selected from a standard deck of 52 playing cards. The first card is not replaced before the second card is selected. Find the probability of selecting a six and then selecting a nine. The probability of selecting a six and then selecting a nine is 0.006
Let the probability that the first card is six be 4/52
Let the probability that the second card is nine be 4/51
Now let determine the probability of selecting a six and then selecting a nine
Probability (P)=(4/52×4/51)
Probability (P)=16÷2,652
Probability (P)= 0.006
Inconclusion if Two cards are selected from a standard deck of 52 playing cards. The first card is not replaced before the second card is selected. Find the probability of selecting a six and then selecting a nine. The probability of selecting a six and then selecting a nine is 0.006
