How can you tell if a graph is function or not
Answer:
If the vertical line intersects the graph in at most one point, then the given graph represents a function. If the vertical line intersects the graph in more than one point, then the given graph does not represent a function.
I HOPE IT HELPS
TAKE CARE
Step-by-step explanation:
Answer:
Step-by-step explanation:
For a graph to be a function, there must not be more than one element in the range for each element of the domain.
If x represents the doman, and y represents the range (as usual, in graphing) then each value on the the x-axis should not have more than one point in the graph on it, directly above it, or directly below it. Like if you had a point (5, 7) and also had point (5, -7), that is not a function. The x, 5, has more than one y-value paired with it.
Visually, any vertical line through the graph should not intersect the graph at more than one point. If it does, then the graph is not a function.
This is called the vertical line test.

uppose that a single die with 8 sides (numbered 1, 2, 3, ... , 8) is rolled twice. What is the probability that the sum of the two rolls equals 5
Answer:
1/16 = 0.0625 = 6.25% probability that the sum of the two rolls equals 5.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Die with 8 sides
This means that the total number of outcomes is [tex]T = 8^2 = 64[/tex]
Outcomes in which the sum of the two rolls is 5:
(1,4), (4,1), (2,3), (3,2)
4 desired outcomes, so [tex]D = 4[/tex]
What is the probability that the sum of the two rolls equals 5?
[tex]p = \frac{D}{T} = \frac{4}{64} = 0.0625[/tex]
1/16 = 0.0625 = 6.25% probability that the sum of the two rolls equals 5.
The probability that the sum of the two rolls equals 5 is 1/16
What is probabilityProbability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
Given a single die with 8 sides (numbered 1, 2, 3, ... , 8) is rolled twice, the total outcome will be:
Total outcome = 8^2
Total outcome = 64
For the sum of two rolls, the expected outcome will be:
E = {(1, 4), (4, 1), (3, 2), (2, 3)}
n(E) = 4
Pr(sum of the two rolls is 5) = 4/64
Pr(sum of the two rolls is 5) = 1/16
Hence the probability that the sum of the two rolls equals 5 is 1/16

A box in a supply room contains 21 compact fluorescent lightbulbs, of which 7 are rated 13-watt, 8 are rated 18-watt, and 6 are rated 23-watt. Suppose that three of these bulbs are randomly selected. (Round your answers to three decimal places.) (a) What is the probability that exactly two of the selected bulbs are rated 23-watt
Answer:
The probability that exactly two of the selected bulbs are rated 23-watt is:
= 19%
Step-by-step explanation:
Number of fluorescent light bulbs in the box = 21
7/21 = 13-watt rated light bulbs
8/21 = 18-watt rated light bulbs
6/21 = 23-watt rated light bulbs
The probability of selected a 23-watt rated light bulb = 6/21 = 28.57%
Size of random selection of bulbs = 3
The probability that 2 out of these 3 bulbs are 23-watt rated light bulbs is:
= 6/21 * 2/3 = 19%
b) The probability of selecting 2 of the 3 bulbs from exactly the 23-watt rated bulbs is the probability of the 23-watt rated bulbs being selected given the chance of selecting 2/3.

James bought 6 cupcakes and a pint of ice cream. He knows his total bill and the pint of ice cream was $5.76, but
he wants to find the price of the cupcakes. How can he determine the price of each cupcake? If the total bill was
$22.26, how much was each cupcake?
Answer:
Each cupcake was $2.75
Step-by-step explanation:
We subtract the price of the ice cream from the total bill $22.26-$5.76=$16.50
We know he only bought the ice cream and cupcakes so once we subtracted the price of the ice cream, we now have the price of the cupcakes all together only
We divide the price of all the cupcakes by the amount of cupcakes to get the price of each individual cupcake $16.50/6=$2.75

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
y = 2x - 3
Now, putting x=0
y= -3
and, x= 1
y= 2(1)-3
y = -1
and, x= 2
y=2 (2)- 3
y = 1
Hence, the coordinates of line is (0, -3), (1, -1) and (2, 1)

Carissa has a 30-year, 5.75% mortgage on her $250,000 home. She has been
paying on it for 5 years, and has recently hit some financial trouble. If her
lender agreed to lower the interest rate on her $231,905.47 balance to 5.25%,
what will her new payment be for the remainder of the loan?
A. $1389.69
B. $1333.09
C. $1330.20
D. $1432.09
Answer:
A. $1389.69
Step-by-step explanation:
To calculate the new monthly mortgage payment that Carissa will start paying going forward, we use the formula for calculating monthly mortgage payments.
The formula is:- M = P { [r ( 1+ r)^n] ÷ [ ( (1+r)^n) -1] }
Here, M is the monthly mortgage payment.
P is the principal
r is the monthly interest rate calculated by dividing your annual interest rate by 12
n is the number of payments(the number of months you will be paying the loan).
Hence, the new principal that Carissa must payback is $231,905.47¢.
The annual interest rate has been reduced to 5.25% from 5.75%.
Therefore, the new monthly interest rate will be obtained by dividing the new annual interest rate by 12
= 5.25%/2
= 0.438%
This is the new monthly interest rate.
Since she has been paying her mortgage loan diligently for 5 complete years. It means she now has just 25 years to complete the payment. If 12 months make up one year, then there are - 12 × 25 = 300 more months to go.
300 is, therefore "n" that is required for the calculation.
All the terms needed for the calculation of her new monthly mortgage are now complete.
P = $231,905.47¢
r = 0.4375%
n = 300
M = 231,905.47 { [0.004375 (1+0.004375) ^300] ÷ [ ( (1+0.004375) ^ 300 ) - 1] }
= 231,905.47 { [ 0.004375 (3.7048) ] ÷ (2.7048) }
= 231,905.47 × 0.005992
M = $1,389.69
Therefore her new monthly mortgage payment will become $1,389.69
