Answer:
D
Step-by-step explanation:
There is no repeated x
The required set of points is y a function of x is C.{(2, 1), (0, 1), (1, 0), (2, 1)}. Option C is correct.
What is set?Sets are an orderly collection of items in mathematics that can be expressed in set-builder or roster form.
A function is a set of ordered pairs where each value of x has only one corresponding value of y. In other words, for a function, there can be only one value of y for each value of x.
So, among the sets of points given, set D, A, and C is not a function of x because the value x=1 has two corresponding values of y.
Therefore, the set of points in which y is a function of x is set C.{(2, 1), (0, 1), (1, 0), (2, 1)} because, for each value of x, there is only one corresponding value of y.

What is the slope of the line?
Answer:
8/5
Step-by-step explanation:
(-1, 4) (4, -4)
-4-4 over 4-(-1)
That is -8/-5.
-8/-5 is simplified to 8/5
Answer:
1.6
Step-by-step explanation:
to find the slope, find two points on the line in the graph.
i'll be using (-1, 4) and (4, -4).
substitute the points into the rise over run equation.
[tex]\frac{rise}{run} = \frac{y1-y2}{x1-x2} =\frac{-4-4}{-1-4}[/tex]

the volume of a cylinder is 8,478 cubic inches, and the radius is 15 inches. Which measurement is closest to the height of this cylinder in inches?
Answer:
The height of the cylinder 'h' = 12 inches
Step-by-step explanation:
Explanation:-
Given Volume of the cylinder = 8,478 cubic inches
Radius of the cylinder = 15 inches
Volume of the cylinder is determined by
[tex]V = \pi r^{2} h[/tex]
8,478 = 3.14 × (15)² h
[tex]h = \frac{8478}{3.14 X 225} = 12 inches[/tex]
The height of the cylinder 'h' = 12 inches

A line plot with the lengths of meteors is shown. Two more identical meteor measurements were added so that the total length of all meteors measured is 16 inches. What is the length of each new meteor?
Answer:
The answer is 1 3/8 (D)
Step-by-step explanation:
If you added the amounts of each tick mark (which would be 13 2/8), and then subtracted it by 16, it would be 2 6/8. 2 6/8 divided by two (because we need to find the length of both of the indentical meteors) would be 1 3/8.
Now, to make sure it is 1 3/8: 13 2/8 + 1 3/8 + 1 3/8 = 16.
It is confirmed, 1 3/8 (Answer D) is the correct answer.
(Also, I took this test and got it correct :D)

the area of a rectangle is 144cm squared.if the length is 16cm. What's the perimeter?
Answer:
50
Step-by-step explanation:
lxb=144
16xb=144
b=9
perimeter=2(l+b)
=2(16+9)
=50 cm
Answer: 50cm squared
Step-by-step explanation:
First we need to find the side lengths,
In order to find the area you do,
A = Length x height
we know that the area is 144 and the length is 16.
144=16 x height
144 = 16 x ?
So know we need to find the height, so we do 144/16= 9
so the height 9 cm.
The question is not asking for the height, but the peremeter.
Peremeter = (Length x 2) + (height x 2)
peremeter= 16 x 2 + 9 x 2
peremeter = 32+18
peremeter = 50 cm squared
so the peremeter is 50 cm squared.

Answer:
21.5≤μ≤25.2
Step-by-step explanation:
The formula for calculating confidence interval is expressed as;
CI = xbar±(z*s/√n)
xbar is the mean = 23.7
s is the standard deviation= 16.3
n is the sample size = 438
z is the z score at 95% confidence level
z = 1.96
Substitute into the formula
CI = 23.7±(1.96×16.3/√438)
CI = 23.7±(1.96×16.3/20.93)
CI = 23.7±(1.96×0.77788)
CI = 23.7±1.5264
CI = (23.7-1.5264, 23.7+1.5264)
CI = (21.4736, 25.2264)
The confidence interval to the nearest tenth is 21.5≤μ≤25.2

In recent years, Japan's population has been declining at a rate of 0.1% per year. If you were to write an exponential equation representing the situation, what would the decay factor be?
A- .999
B- 0.99
C- .91
D- 1.001
the decay factor for the given decay rate is 0.999
Given :
In recent years, Japan's population has been declining at a rate of 0.1% per year.
we need to find the decay factor for the given exponential rate.
The rate of decay is 0.1%. To remove percentage we divide by 100
so , [tex]\frac{0.1}{100}=0.001[/tex]
The decay rate is 0.001
To find out decay factor , we subtract decay rate from 1
decay factor is 1- decay rate
Decay factor is 1-0.001=0.999
So the decay factor for the given decay rate is 0.999

irrational numbers are closed under subtraction true/false
Answer:
False
Step-by-step explanation:
a+(-a)=a-a = 0 which means irrational numbers are not closed under addition or subtraction.
False. Irrational numbers are not closed under subtraction.
Given data:
Closure under subtraction means that if you subtract two irrational numbers, the result will always be another irrational number.
However, this is not true for irrational numbers.
For example, consider the irrational numbers √2 and √2 + √2. Both of these numbers are irrational. However, when we subtract √2 from √2 + √2, we get:
(√2 + √2) - √2 = √2
The result, √2, is still an irrational number. But if we subtract two irrational numbers like √2 from √2, we get:
√2 - √2 = 0
The result, 0, is a rational number, not an irrational number.
