Determine if each statement about the relation {(3,7),(5,1),(6,4),(2,5)} is true or false.
a. The domain of the relationship is {2,3,5,6}.
b. The range of the relation is {1,4,5,7}.
c. The value 5 is a member of both the domain and range.
Answer:
a. true
b. true
c. True
Step-by-step explanation:
a. The domain of a relation includes all possible set of data that are the x-values. Therefore, the domain of the relationship given would be: {2, 3, 5, 6}.
a is True.
b. The range includes all corresponding y-values. Therefore,
Range would be {1 4, 5, 7}
b is Tire.
c. There's 5 on both range and domain.
c is hungry.

Answer to5)y=3
Answer to q9)x=3
5. y = 3.
6. y = (2/3)x.

9. x = 3.
10. y = - 3x.
What is a graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
5. The graph of this function is constant for all values of x, y = 3.
6. The graph of this function has points (0, 3) and (3, 2).
m = (2 - 0)/(3 - 0).
m = 2/3.
2 = (2/3)×3 + b.
2 = 2 + b.
b = 0.
y = (2/3)x.
7. The graph of this function has points (0, 1) and (3, 2).
m = (2 - 0)/(3 - 1).
m = 2/2.
m = 1.
2 = 1(3) + b.
2 = 3 + b.
b = -1.
y = x - 1.
8. The graph of this function has points (- 3, 0) and (0, 3).
m = (3 - 0)/(0 + 3).
m = 1.
3 = 1(0) + b.
b = 3.
y = x + 3.
9. The graph of this function is a vertical line parallel to the y-axis,
x = 3.
10. The graph of this function has points (0, 0) and (- 1, 3).
m = (3 - 0)/(- 1 - 0).
m = 3/ - 1.
m = - 3.
0 = - 3(0) + b.
b = 0.
y = - 3x.

Determine whether each equation represents a proportional relationship
1) y = 2x + 4
2) y = 2x
Answer:
(1) does not represent a proportional relationship, but (2) does.
Step-by-step explanation:
(1) y = 2x + 4 has a nonzero y-intercept, so it is not a proportional relationship.
(2) y=2x is a proportional relationship. It is of the form y=kx, where k is the constant of proportionality.
You roll two number cubes.
Let event A = The number rolled on the first cube is 6.
Let event B = The sum of the numbers rolled is 11.
What does P(BIA) represent?
Answer:
A. the probability that the sum is 11,given that the first number cube shows a 6
The correct answer is the probability that the sum is 11, given that the first cube shows the number 6.
What is conditional probability?Conditional probability is defined as the likelihood of an event or outcome occurring, based on the occurrence of a previous event or outcome.
Let A and B be two events as given.
B|A = "Event B given Event A"
In other words, the probability Pr(B|A) says "event A has already happened, now what is the chance of event B"
P(B|A) is also called the "Conditional Probability" of B given A.
In our case, the probability Pr(B|A) represents "the probability that the sum is 11, given that the first cube shows the number 6".
Hence, the correct answer is the probability that the sum is 11, given that the first cube shows the number 6.

The three inside angles (A, B and C) of a right angled triangle are in the ratio 7:18:11
The smallest angle is 35°
Work out out angles a,b and ,
Answer:
Angle A =35 degrees, Angle B = 90 degrees, and Angle C = 55 degrees
Step-by-step explanation:
So all the angles added up would be 180. Let's use the variable x. The angles would be 7x, 18x, and 11x.
The smallest angle is 35, and 7x is the smallest out of all them since x has to be positive.
7x = 35
x = 5
Then substitute x into each angle.
They would be 35 degrees, 90 degrees, and 55 degrees

Step-by-step explanation:
So easily
the mark down is 71 percent or 0.71
Techinacially your just paying 29 percent of the product becuase 71 percent is gone
So just multiply 0.29 by 202.11
You’ll get 58.61 as the final sale price
If you do it the hard way, still the same answer
Answer: $58.61
Step-by-step explanation:
Markdown: 71% × 202.11
0.71 × 202.11 = 143.4981
143.4981 ≈ 143.50
Markdown ≈ $143.50
Sale price: Original price - Markdown
$202.11 - $143.50 = $58.61
Sale price ≈ $58.61

11. An experiment is set up to study the weights of 45 frogs after they are given a hormone treatment. The population mean is 22.70 grams with a standard deviation of 2.96 grams.
What is the standard error of the sample mean? Round your answer to the nearest hundredth.
The standard error of the sample mean is approximately (? ).
Answer: The standard error of the sample mean = 0.44
Step-by-step explanation:
Standard error of the sample mean = [tex]\dfrac{\sigma}{\sqrt{n}}[/tex] , where [tex]\sigma[/tex] = population standard deviation , n= sample size.
Given : n= 45 , [tex]\sigma= 2.96[/tex] grams
