Which table contains only values that
satisfy the equation y = 6x +2?
FOR BRAINLIST!!
Answers
Answer:
table C
Step-by-step explanation:
We have to try to substitute the x with its value and y with its value. If the equality is satisfied, the points are points of the line
Table A
0 = 0 + 2
0 = 2 false, table A can’t be the answer
Table B
2 = 2 true
4 = 6 + 2
4 = 8 false, table B can’t be the answer
Table C
2 = 2 (true)
8 = 6+2 ; 8=8 (true)
14 = 12 + 2 ; 14= 14 (true)
20 = 18 + 2 ; 20=20 (true)

Part A: The area of a square is (4a2 − 20a + 25) square units. Determine the length of each side of the square by factoring the area expression completely. Show your work. (5 points)
Part B: The area of a rectangle is (9a2 − 16b2) square units. Determine the dimensions of the rectangle by factoring the area expression completely. Show your work. (5 points)
Answers
Answer:
The length of each side is (2a-5) units
Step-by-step explanation:
4a^2 - 20a +25
= (2a)^2 - 20a + (-5)^2
=(2a - 5)^2
(9a^2 - 16b^2)
= (3a)^2 - (4b)^2 this is the difference of two squares, the factors are therefore
= (3a + 4b) * (3a - 4b)
The dimensions of the rectangle are:
one pair of opposite sides are 3a + 4b
and the other pair of opposite side perpendicular to the first pair is 3a - 4b

A rectangular room is 5 meters longer than it is wide, and its perimeter is 22 meters. Find the dimension of
the room.
Answers
Answer:
The dimension of the room is 8m by 3m
The length and width of the rectangle are 8 meters and 2 meters.
Given,
A rectangular room is 5 meters longer than it is wide.
Perimeter = 22 meters.
We need to find the dimension of the room.
What is the perimeter of a rectangle?A rectangle perimeter is given by :
P = 2 ( length + wide )
Find the length and width of the rectangle.
Let width = W
Let length = L
L = W + 5
Find the perimeter of the rectangle.
P = 2 ( L + W )
P = 22
22 = 2 ( W + 5 + W )
Divide both sides by 2.
11 = W + 5 + W
11 = 2W + 5
Subtract 5 on both sides.
11 - 5 = 2W + 5 - 5
6 = 2W
Divide both sides by 2.
3 = W
W = 3
We see that W = 2 and L = W + 5 = 3 + 5 = 8.
Thus the length and width of the rectangle are 8 meters and 2 meters.

What is the equation of the graph below?
Answers
Answer:
y = sin(x + 90°)
Step-by-step explanation:
cos 0 = 1
Since the point (0, 1) is on the graph, this graph is y = cos x, but that is not a choice, so this must be the graph of the sine function with a horizontal translation.
sin 0 = 0
sin 90° = 1
The translation is 90°.
Answer: y = sin(x + 90°)

Step-by-step explanation:
Patricia and Whitney began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Patricia took a test in English and earned a 76.5, and Whitney took a test in Math and earned a 64.5. Use the fact that all the students' test grades in the English class had a mean of 73.1 and a standard deviation of 10.5, and all the students' test grades in Math had a mean of 60.9 and a standard deviation of 10.7 to answer the following questions.
a. Calculate the Z-score for Kimberly's test grade.
b. Calculate the z-score for Karina's test grade.
c. Which person did relatively better?
Answers
Answer:
a) The Z-score for Patricia's test grade is 0.32.
b) The z-score for Whitney's test grade is of 0.34.
c) Due to the higher z-score, Whitney's did relatively better.
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
a. Calculate the Z-score for Patricia's test grade.
Patricia took a test in English and earned a 76.5. Students' test grades in the English class had a mean of 73.1 and a standard deviation of 10.5.
This means that [tex]X = 76.5, \mu = 73.1, \sigma = 10.5[/tex]
The z-score is:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{76.5 - 73.1}{10.5}[/tex]
[tex]Z = 0.32[/tex]
The Z-score for Patricia's test grade is 0.32.
b. Calculate the z-score for Whitney's test grade.
Whitney took a test in Math and earned a 64.5. Students' test grades in Math had a mean of 60.9 and a standard deviation of 10.7.
This means that [tex]X = 64.5, \mu = 60.9, \sigma = 10.7[/tex]
The z-score is:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{64.5 - 60.9}{10.7}[/tex]
[tex]Z = 0.34[/tex]
The z-score for Whitney's test grade is of 0.34.
c. Which person did relatively better?
Due to the higher z-score, Whitney's did relatively better.

Answer:
Option (3)
Step-by-step explanation:
Given sequence is,
8, -8, 8,...........
Ratio of the 2nd and 1st term = [tex]\frac{-8}{8}[/tex]
= -1
Ratio of 3rd and 2nd term = [tex]\frac{8}{-8}[/tex]
= -1
Therefore, there is a common ratio 'r' = (-1)
And the sequence is a geometric sequence.
Explicit formula for the nth term of a geometric sequence is given by,
[tex]T_n=a(r)^{n-1}[/tex]
Here, 'a' = First term of the sequence
r = Common ratio
n = nth term
For the given sequence xth term of the sequence will be,

In this activity, you will predict the probability of an event from the relative frequency of the event. Pablo has some one-, five-, ten-, and twenty-dollar bills in his wallet. He randomly pulls one bill out of his wallet and replaces it. He does this 40 times as part of an experiment. The table shows the number of times Pablo pulls out each bill.
Bill Value Number of Times Picked
$1 6
$5 16
$10 10
$20 8
Part A
What is the relative frequency of drawing a one-dollar bill?
Part B
What is the relative frequency of drawing a five-dollar bill?
Part C
What is the relative frequency of drawing a ten-dollar bill?
Part D
What is the relative frequency of drawing a twenty-dollar bill?
Part E
Which type of bill is Pablo most likely to have the most of? How do you know?
Part F
Which type of bill is Pablo most likely to have the least of? How do you know?
Part G
Would you be surprised if Pablo had fewer twenty-dollar bills than one-dollar bills? What if he had fewer tens than ones? Why or why not?
Answers
Answer:
Part A
6/40 = 0.15
Part B
16/40 = 0.4
Part C
10/40 = 0.25
Part D
8/40 = 0.20
Part E
The relative frequency of drawing a five-dollar bill is higher than the other relative frequencies. So, I can predict that Pablo is most likely to have more five-dollar bills than any of the others.
Part F
The relative frequency of drawing a one-dollar bill is lower than the other relative frequencies. So, I can predict that Pablo is most likely to have fewer one-dollar bills than bills of any other denomination.
Part G
It would not be a surprise if Pablo had fewer twenties than ones. The experiment was conducted only 40 times, and the numbers of times one-, ten-, and twenty-dollar bills were drawn are not very far apart. So, the number of twenties could be more or less than the number of ones. The same goes for tens and ones.
If you're on Plato an on slide 20 this Answer is for you:
If Pablo does an experiment 100 times, will the relative frequency be more accurate or less accurate than if he did the experiment 40 times? Why?
Answer: As the number of trials increases, the relative frequency becomes closer to the probability of the event. So, the relative frequency would be more accurate if the experiment were repeated 100 times rather than 40 times.
P(A) = 20%. P(B) = 50%. P(BIA) = P(B). What is P(A and B)?
Answers
Answer:
P(A and B) = 0.1 = 10%
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question, we have that:
[tex]P(A) = 0.2, P(B|A) = 0.5[/tex]
What is P(A and B)?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
[tex]P(A \cap B) = P(B|A)*P(A) = 0.5*0.2 = 0.1[/tex]
P(A and B) = 0.1 = 10%
