Is this a Function or NOn function
Answer: function
Step-by-step explanation: Here were given a relation in
the form of a graph and we're asked if it represents a function.
In this situation, we would use what is called the vertical line test.
In other words, if we can draw a vertical line that passes through more
than one point on the graph, then the relation is not a function.
In this problem, there is no way to draw a vertical
line that passes through more than one point on a graph.
Therefore, this relation must be a function.

.3333333333 is equivalent to
which fraction: 3/33 or 3/1 or
33/33 or 1/3
Answer:
1/3
Step-by-step explanation:
If you times 1/3 by 3, you will end up with one whole (1).
If you times .3333333... by 3, you will end up with a number that is pretty close to "1."
3/33 equals 0.090909... or 1/11, so this answer is not right.
3/1 equals 3 while 33/33 equals 1.
Hope that answers your question!

She uses 18 square inches of paper for each card How many square feet of paper does she need to make 150 cards
Answer:
225
Step-by-step explanation:
Well, we already know how many square inches each card is. 18. All we need to do is multiply that number by 150 because we need to make 150 cards. So:
18 x 150 = 2,700inches.
Now all we need to do is divide the number of inches by the amount each foot is. Each foot is 12 inches. So:
2,700 ÷ 12 = 225.
225 is your answer.
Hope this helps and have a nice day!

Some the equation 4y-6x=12 for y.
Answer:
y = 3 + 1.5x
Step-by-step explanation:
4y = 12 + 6x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Divide each side by '4'.
y = 3 + 1.5x
Simplifying
y = 3 + 1.5x
Answer:
y = 3/2x + 3
Step-by-step explanation:
Given :
4y - 6x = 12To Do :-
To solve out for y .Solution :-
The given equation is ,
⇒ 4y - 6x = 12
⇒ 4y = 6x + 12
⇒ y = ( 6x + 12 )/4
⇒ y = 3/2x + 3

Ox= 2
Ox=11
Answer:
[tex] \huge \boxed{x = - 1}[/tex]
Step-by-step explanation:
[tex] \frac{2x - 10}{4} = 3x \\ [/tex]
Multiply through by 4 to eliminate the fraction
That's
[tex]4 \times \frac{2x - 10}{4} = 4(3x) \\ 2x - 10 = 12x[/tex]
Subtract 12x from both sides of the equation
[tex]2x - 12x - 10 = 0 \\ - 10x - 10 = 0 \\ - 10x = 10[/tex]
Divide both sides by - 10
[tex] \frac{ - 10x}{ - 10} = \frac{10}{ - 10} \\ [/tex]
We have the final answer as
x = - 1Hope this helps you
Find the equation of the line with slope 2/5 and y-intercept (0,−2).
Answer:
[tex]\boxed {\tt y=\frac{2}{5}x-2}[/tex]
Step-by-step explanation:
If the slope and y-intercept is known, the equation of a line can be written using slope-intercept form.
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept.
We know that the slope is 2/5.
The y-intercept is (0,-2). For this form, we only need the y-coordinate, which is -2 in this case. Therefore, we can say the y-intercept is -2.
[tex]m=2/5 \\b= -2 \\[/tex]
Substitute the values into the formula.
[tex]y=2/5x+ (-2)[/tex]
[tex]y=2/5x-2[/tex]
The equation of the line is y=2/5x-2

How do you simplify the expression (s+t)3
Answer:
3s + 3t
Step-by-step explanation:
To simplify this expression, all you need to do is distribute the 3, which means you basically multiply whatever is in the parentheses by 3:
(s + t) * 3 =
3s + 3t
And that is the simplified form for this expression.

Answer:
y-intercept: (0, 5); slope: 1/4
Step-by-step explanation:
The slope (m) is found from ...
m = (y2 -y1)/(x2 -x1)
Using the first two points in the table, this is ...
m = (8 -6)/(12 -4) = 2/8 = 1/4 . . . . . eliminates choices A and C
__
Then, the point-slope form of the equation of the line can be written as ...
y -y1 = m(x -x1)
y -6 = (1/4)(x -4) . . . fill in known values
y = 1/4x -1 +6 . . . . . add 6
y = 1/4x +5
Then the value of y when x=0 is ...
y = 0 +5 = 5
So, the y-intercept is (0, 5) and the slope is 1/4, matching the last choice.
Write a linear equation of the line that passes through (6, -1) and is parallel y
= 2x - 1
O y = -1/2 x + 2
O y = 2x - 2
O y = 2x - 13
O y = 2x - 11
A human resource company performs employment screening for large companies in southern California. Recently, the company began working with a new client and formulated a new test just for this company. Thirty people were given the test. The data below reflect the scores of those 30 people. The human resource company has in the past issued a rejection letter with no interview to the lower 16% taking the test. They also send the upper 2.5% directly to the company without an interview. Everyone else is interviewed. Based on the data and assuming a bell-shaped distribution, what scores should be used for the two cutoffs?
79 79 7151 65 71 65 90 60 62 78 76 88 69 65
91 72 56 61 83 61 78 68 66 52 79 88 74 71 69
A score of ________should be used as the cutoff for the lower 16% and a score of________ (Round to the nearest integer as needed.)
Answer:
A score of 61 should be used as the cutoff for the lower 16% and a score of 92 should be used as the cutoff for the upper 2.5%.
Step-by-step explanation:
The data set for the scores of the 30 people are:
S = {79, 79, 71, 51, 65, 71, 65, 90, 60, 62, 78, 76, 88, 69, 65, 91, 72, 56, 61, 83, 61, 78, 68, 66, 52, 79, 88, 74, 71, 69}
Compute the mean and standard deviation:
[tex]\mu=\frac{1}{n}\sum X=\frac{1}{30}\times 2138=71.27\\\\\sigma=\sqrt{\frac{1}{n-1}\sum (X-\mu)^{2}}=\sqrt{\frac{1}{30-1}\times 3343.8667}=10.74[/tex]
It is provided that in the past the company issued a rejection letter with no interview to the lower 16% taking the test.
That is the probability of no interview is, P (X > x) = 0.16.
That is, P (Z > z) = 0.16.
The z-score corresponding to this probability is, -1.
Compute the value of x as follows:
[tex]z=\frac{x-\mu}{\sigma}\\\\x=\mu+z\cdot \sigma\\\\=71.27+(-1\times 10.74)\\\\=60.53\\\\\approx 61[/tex]
It is also provided that the upper 2.5% directly to the company without an interview.
That is the probability of no interview is, P (X < x) = 0.025.
That is, P (Z < z) = 0.025.
The z-score corresponding to this probability is, 1.96.
Compute the value of x as follows:
[tex]z=\frac{x-\mu}{\sigma}\\\\x=\mu+z\cdot \sigma\\\\=71.27+(1.96\times 10.74)\\\\=92.3204\\\\\approx 92[/tex]
Thus, the complete sentence is:
A score of 61 should be used as the cutoff for the lower 16% and a score of 92 should be used as the cutoff for the upper 2.5%.
you have $8.00 to make copies. each copy costs $0.40. write and solve an inequality that represents the number of copies you can make?
Answer:
0.40x[tex]\leq \\[/tex]8
The inequality that represents the number of copies you can make is x ≤ 20. This means you can make a maximum of 20 copies with your $8.00 budget.
To determine the number of copies you can make with a given budget, you need to write and solve an inequality using the cost per copy and your available funds.
1. Let's denote the number of copies as "x".
2. The cost of each copy is $0.40.
3. The total cost of the copies can be calculated by multiplying the number of copies by the cost per copy, which gives us 0.40x.
4. You have $8.00 available for copying.
5. To represent the inequality, we compare the total cost of the copies (0.40x) to the available funds ($8.00).
6. Since you want to ensure that the cost of the copies does not exceed your budget, the inequality is: 0.40x ≤ 8.00
To solve the inequality and find the maximum number of copies you can make, divide both sides of the inequality by 0.40:
= (0.40x) / 0.40 ≤ (8.00) / 0.40
= x ≤ 20
