Answer: if we want to find a point of 17*m(x) + 2, one is (1, 155)
Step-by-step explanation:
I guess you want to know a point in the function
h(x) = 17*m(x) + 2
we know that m(1) = 9 (because m(x) has the point (1, 9) in it's graph)
then h(1) = 17*m(1) + 2 = 17*9 + 2 = 155
so this function has the point (1, 155)
What is the length of CD? In this diagram,
ABC ~ EDC.
Hey there!
Answer:
CD = 3.
Step-by-step explanation:
Since the triangles are similar, we can set up a ratio to determine the other side-lengths:
[tex]\frac{12-x}{18} =\frac{x}{6}[/tex]
Cross multiply:
[tex]6(12-x) = 18x[/tex]
Distribute the '6':
[tex]72-6x = 18x[/tex]
Combine like terms and simplify:
[tex]72 = 24x[/tex]
[tex]x = 3[/tex]
Therefore, the length of CD is 3.

WILL GIVE BRAINLIEST! Alice, Bob, and Carrie can all choose a number from 1 to 10 (inclusive).
(a) Find the number of ways they can choose their numbers if all three numbers are different.
(b) Find the number of ways they can choose their numbers if they have to choose exactly two different numbers among all three people. (For example, Alice and Bob both pick 1, and Carrie picks 2.)
Answer:
(a) 720
(b) 180
Step-by-step explanation:
We are given 10 numbers (1,2,3,4,.....,10).
(a) 3 unique numbers are to be chosen by Alice, Bob and Carrie.
Number of ways to choose the 1st number = 10
Number of ways to choose the 2nd number = 9 (1 number chosen earlier can't be chosen again)
Number of ways to choose the 3rd number = 8 (2 numbers chosen earlier can't be chosen again)
Total number of ways of choosing 3 unique numbers = [tex]10 \times 9 \times 8 \Rightarrow 720[/tex]
(b)
Number of ways of choosing 1st number = 10 (no restrictions)
Number of ways of choosing 2nd number = 9 (1 number chosen earlier can't be chosen again)
Now, restriction on the 3rd number to be chosen is that one of the two already chosen number should be chosen again.
So, number of ways to choose 3rd number = 2
the number of ways they can choose their numbers if they have to choose exactly two different numbers among all three people =
[tex]10 \times 9 \times 2 \Rightarrow 180[/tex]
Hence, the answers are:
(a) 720
(b) 180
What are the solutions to the quadratic equation 4x^2 = 64?
A. x = −16 and x = 16
B. x = −8 and x = 8
C. x = −4 and x = 4
D. x = −2 and x = 2
Answer:
C
Step-by-step explanation:
Given
4x² = 64 ( divide both sides by 4 )
x² = 16 ( take the square root of both sides )
x = ± [tex]\sqrt{16}[/tex] = ± 4
Solutions are x = - 4 and x = 4 → C

Find the number of ways a math test can be made with a 20 question test bank and a 15 question test
Answer: we can make 15,504 different math tests
Step-by-step explanation:
Ok, we have a bank with 20 questions (Q1, Q2........ , Q20)
and we want to make a test with 15 of those 20 questions.
As the order of the questions does not matter in the thest ( is the same if the order is Q1, Q2, ...., Q15 than if the order is Q15, Q14, ....., Q1 )
So we only want the number of combinations.
When we have N elements and we want to create groups of K elements, the total number of combinations is:
[tex]C = \frac{N!}{(N - K)!*K!}[/tex]
Here N = 20 and K = 15
[tex]C = \frac{20!}{5!*15!} = \frac{20*19*18*17*16}{5*4*3*2*1} = 15,504[/tex]
So we can make 15,504 different math tests
Chen buys 4 tickets to a soccer game. The total cost before taxes is $80. Which equation would you use to determine the price, p, of the ticket? A 4p=80 B 80p=4 C 4+p=80 D p/4=80
Answer:
A. 4p=80
Step-by-step explanation:
Total Cost of 4 tickets=$80
Price=p
Quantity=4
Total cost=price×quantity
80=p×4
80=4p
80=4p is the equation that can be used to determine price
From the equation
80=4p
Divide both sides by 4
80/4=4p/4
20=p
Price is $20 per ticket
Answer:
4p = 80
Step-by-step explanation:
Total cost before tax = $80
Number of tickets purchased = 4
Price 'p' of each ticket
p = total price of ticket / number of tickets purchased
p = 80 / 4
Multiplying both sides by 4
4p = 80

A printer takes 30 minutes to print a banner and a poster. I will take 50 minutes to print a banner and three posters. How long does it take to print a banner?
Answer:
It takes the printer 20 minutes to print a banner
Step-by-step explanation:
Notice that there are two unknowns in this problem: the time to print a poster and the time to print a banner. Let's assign the letter "b" to the time it takes to print a banner, and "p' the time it takes to print a poster.
So we can write the following two equations involving the total amount of time that takes to print in the two cases:
[tex]b+p=30\\b+3p=50[/tex]
We can solve for the unknown "p" by subtracting term by term in the equation set above:
[tex]b+3p=50\\b+p=30\\\\b-b+3p-p=50-30\\2p=20\\p=10[/tex]
So it takes 10 minutes to print each poster, we can find the time it takes to print the banner by using the value we just found in one of the equations:
[tex]b+p=30\\b+10=30\\b=20[/tex]
So, it takes 20 minutes to print a banner.

Band rues charges $950 to play all night.
DJ phoria charges $350 plus $5 for each ticket sold.
Write a linear equation for the cost of the DJ where y = the total cost and x = the number of tickets sold. The equation for the Band is y = 950.
Graph each equation on the same coordinate plane and find the number of tickets for which the cost of the band and the DJ would be equal. Make sure to name and number the axes of your graph. Also, solve the system of equations analytically, showing all work.
Answer:
120 Tickets
Step-by-step explanation:
Band rues charges $950 to play all night.
Total Cost, y=$950DJ phoria charges $350 plus $5 for each ticket sold.
Total Cost, y=$(350+5x), x = the number of tickets sold.(a)The graph is attached.
From the point of intersection of the two lines, the number of tickets for which the cost of the band and the DJ would be equal is 120 tickets.
(b)
Given the two linear equations
y=950
y=350+5x
Therefore:
950=350+5x
950-350=5x
5x=600
x=120
Therefore, the number of tickets at which the cost of the band and the DJ would be equal is 120, just as obtained above.
The members of a men’s club have a choice of wearing black or red vests to their club meetings. A study done over a period of many years determined that the percentage of black vests worn is 70%. If there are 10 men at a club meeting on a given night, what is the probability, to the nearest thousandth, that at least 8 of the vests worn will be black?
Answer:
Step-by-step explanation:
Let x be a random variable representing the number of the members of a men’s club that wear black vests to their club meetings. This is a binomial distribution since the outcomes are two ways. It is either they wear black or red. The probability of success, p = 70/100 = 0.7
The probability of failure, q would be 1 - p = 1 - 0.7 = 0.3
a) Number of samples, n = 10
We want to determine P(x ≤ 8)
From the binomial distribution calculator,
P(x ≤ 8) = 0.851
Answer:
The probability that at least 8 of the vest worn will be black is 0.75490
Step-by-step explanation:
The parameters given are;
The percentage of black vest worn = 70%, p₀ = 0.7
Number of men in sample, n = 10
Required number of men who wore black = 8
Proportion of sample [tex]\hat p[/tex] = 8/10 = 0.8
The z score of a proportion is given by the relation;
[tex]z = \dfrac{\hat p - p_0}{\sqrt{\dfrac{p_0(1 - p_0)}{n} } }[/tex]
Plugging in the vales, we have;
[tex]z = \dfrac{0.8 - 0.7}{\sqrt{\dfrac{0.7(1 - 0.7)}{10} } } = 0.69[/tex]
From the z table we have probability = p(z < 0.69) = 0.75490
The probability that at least 8 of the vest worn will be black = 0.75490.
what is the inequality shown
Answer:

Step-by-step explanation:
Because the nembers before 0 are negitave and the ones after it are positive the equation to find the answer is (-3)(+2) and if you don't know how you add the two like: -3 +2
- negative
+ positive (which also goes for adding 2)
The inequality is shown in that number line 3 ≥ x > 2
What is Number Line?In math, a number line can be defined as a straight line with numbers arranged at equal segments or intervals throughout. A number line is typically shown horizontally and can be extended indefinitely in any direction.
In order to express inequalities on a number line, we mark a straight line and indicate the endpoints with either an open circle or a closed circle.
An open circle indicates that it does not include the value.
A closed circle indicates that the value is included.
These numbers solution set consists of all real numbers between -3 and 2.
Since 2 has an open circle, it excludes '2,' but it does include everything higher, up to and including -3, which has a closed circle.
Thus, we can represent this using the inequality 3 ≥ x > 2.

The experimental probability is calculated based on the results of the experiment; since the name Ted was chosen 26 times out of 123, the experimental probability is [tex]\boxed{\frac{26}{123}}.[/tex]
Typically, the theoretical probability assumes that events are chosen randomly; since the name Ted is one of the 6 in the hat, the theoretical probability is [tex]\boxed{\frac{1}{6}}.[/tex]
If we increased the number of names in the hat, we would expect both the experimental and theoretical probability to decrease, since there are now more names to choose from. Similarly, if we decreased the number of names in the hat, the experimental and theoretical probability would increase.
Assume that y varies directly with x . Ify = 18when x = 6 , findywhen x = 5 . Write and solve a direct variation equation to find the answer. y =
Answer:
y = 15
Step-by-step explanation:
It's given in this question that y varies directly with x.
That means, y ∝ x
⇒ y = kx (where k is the proportionality constant)
If y = 18 when x = 6,
⇒ 18 = 6k
⇒ k = 3
Therefore, relation between x and y is,
y = 3x
From this relation, if x = 5
y = 3×5
y = 15
Therefore, for x = 15 value of y will be 15.

Sergio wants to glue a ribbon around the top of a cube box with a volume of V. Which expression gives the length of the ribbon?
Answer:
Length of ribbon = 4 × ∛(V)
Step-by-step explanation:
The question is incomplete without the options of the expression to choose from.
Find attached the diagram used in solving the question.
Volume of a cube = side × side × side
Let side = s
Volume of a cube = side³ = s³
Volume of cube box = V
V = s³
s = ∛(V)
The shape of the top of a cube box is a square.
Length of the ribbon to be used to glue round the top of a cube box = Perimeter of a square
Perimeter of a square = length + length + length + length = 4× length
Length = side
Perimeter of a square = 4×s
Perimeter of a square = 4 × ∛(V)
Length of ribbon = 4 × ∛(V)
