because at least one input maps to more than one output.
-1 is giving more than one output. (-1,0) (-1,2)
for it to be a function, -1 must have only ONE output! :D
Camila’s box holds 363 balls. Each layer has 33 balls. How many layers does the box have?
Answer:
The box has 11 layers
Step-by-step explanation:
Since there are 363 balls and each layer has 33 balls, we have to divide 363 by 33.
363÷33= 11
So, there will be 11 layers in the box.

Philip is allowed to watch 2 hours of television each day Monday through Thursday and 4 hours of television each day Friday through Sunday. Which of the following equations can be used to calculate the number of hours of television Philip is allowed to watch in x weeks?
Answer:
x(4 × 2) + x(3 × 4)
Step-by-step explanation:
The question says "which of the following equations" which infers you have already been given options. However, none were provided in the question so my answer may be slightly different than the given options as there's several ways to solve this problem.
Monday through Thursday = 4 days × 2 hours per day
Friday through Sunday = 3 days × 4 hours per day
To find the total for one week, add the two expressions together:
(4 × 2) + (3 × 4)
The question states for "x weeks" so:
x(4 × 2) + x(3 × 4)
This is one way the equation can be written
Another way is:
x[(4 × 2) + (3 × 4)]
If neither of these are answers for your mutliple choice question, then please provide the options and I will let you know which is correct

Answer:
(0,5) or 5
Step-by-step explanation:
the y intercept is the point where the line crosses the y-axis. given this info, its given that the y intercept would be 5, or (0,5) in coordinates ^_^
Answer:
0,5
Step-by-step explanation:
So this is actually simpler than it looks. All you have to do is see what point starts out with the x coordinate at zero. The center of the graph is 0,0, so the y intercept is 0,5 because that is the first graph of y. The order is 0,5 1,6 2,7 so on and so on. Hope my explanation made sense.

10 square units
20 square units

Answer:
Choice B
Step-by-step explanation:
The area of the triangle is 10 square units, the correct option is B.
What is a Triangle?A triangle is a polygon with three sides, angles, and vertices.
The triangle is classified into various types on the basis of the angle and on the basis of equality of the length of the sides.
The vertices of the triangle are at:
(-3,3), (2, 3), and (4,7).
The area of the triangle has to be determined.
The length of the sides will be calculated using the distance formula.
side 1 = [tex]\rm \sqrt { (3-3)^2 + ( 2 +3)^2}[/tex] = 5 units
side 2 = 2√5 units
side 3 = √65 units
The height of the triangle is determined by calculating the distance from (4, 7) to (4, 3).
The height of the triangle = 4 units
The area of a triangle is given by,
A = (1/2) * base * height
A = (1/2) * 5 * 4
A = 10 square units

The mean cost to repair the smoke and fire damage that results from home fires of all causes is $11,389 (HomeAdvisor website, December 2014). How does the damage that results from home fires caused by careless use of tobacco compare? The DATAfile named TobaccoFires provides the cost to repair smoke and fire damage associated with a sample of 55 fires caused by careless use of tobacco products. Using past years' data, the population standard deviation can be assumed known with σ = $3,027.
Answer:
The alternative is characterized in the interpretation section following the table, as per the case mentioned.
Step-by-step explanation:
According to the question:
The sample mean will be:
⇒ [tex]\bar{x}=\frac{\Sigma x}{n}[/tex]
[tex]=\frac{1050500}{55}[/tex]
[tex]=19100[/tex]
The critical value of z ([tex]z_e=1.96[/tex]) seems to be the 95 % confidence interval. So the required confidence interval will be:
= [tex]\bar{x} \ \pm \ x_{critical}\frac{\sigma}{\sqrt{n} }[/tex]
= [tex]19100 \ \pm \ 1.96.\frac{3027}{\sqrt{25} }[/tex]
= [tex]19100 \ \pm \ 800[/tex]
Consequently, the average cost of repairing flames and smoke injury can outcomes from household fires started by careless tobacco is therefore estimated at quite a 95 percent confidence interval ($18300, $19900). The 95 percent confidence interval indicates that the average estimated price of fires results through the use of tobacco is somewhat more costly than that of the average cost of flames results from across all factors that cause.The 95% confidence interval is ($18300 , $19900) and according to the confidence interval, the average estimated price of fires results through the use of tobacco is somewhat more costly than that of the average cost of flames results from across all factors that cause.
Given :
The mean cost to repair the smoke and fire damage that results from home fires of all causes is $11,389.Sample size, n = 55.The population standard deviation can be assumed known with σ = $3,027.First, find the sample mean by using the following formula:
[tex]\rm \bar{x}=\dfrac{\sum x}{n}[/tex]
[tex]\rm \bar{x}=\dfrac{1050500}{55}[/tex]
[tex]\rm \bar {x} = 19100[/tex]
Now, for 95% confidence level, the confidence interval will be:
[tex]= \rm \bar{x} \pm x_{critical} \dfrac{\sigma}{\sqrt{n} }[/tex]
[tex]\rm = 19100\pm 1.96\times \dfrac{3027}{\sqrt{55} }[/tex]
[tex]=19100\pm 800[/tex]
The 95% confidence interval is ($18300 , $19900).
According to the confidence interval, the average estimated price of fires results through the use of tobacco is somewhat more costly than that of the average cost of flames results from across all factors that cause.

A farm stand sells oranges in 3-lb bags for $3.75. What equation represents the cost, c, for p pounds of oranges? Think: how much will 1-lb of oranges cost?
A c = 1.25p B p = 1.25c
C c = 3.75p D p = 3.75c
Answer:
A
Step-by-step explanation:
It’s not B, because it’s saying each pound is 1.25 multiplied by the cost. We are looking for the cost, not the amount of pounds.
it isn’t C, because the oranges are sold in 3 pound bags, and the equation is comparing the cost of a 3 pound bag to 1 pound of oranges.
And it isn’t D, because D does the same thing as B, but with The cost of a 3 pound bag.
An equation is formed of two equal expressions. The correct option is A, c=1.25p.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that the farm stand sells oranges in 3-lb bags for $3.75. Therefore, the cost of the oranges for a pound is,
Cost of a pound of oranges = $3.75 / 3
= $1.25
Now, if the cost,c for p pounds of oranges is,
Cost, c = Cost of a pound of oranges × Number of pounds
= $1.25 × p
c = 1.25p
Hence, the correct option is A, c=1.25p.
