If the relation is a function, list the domain and range. If the relation is not a function, choose "not a function". C = {(9, 1) (8, -3) (7, 5) (-5, 3)} Domain: {9, 8, 7, -5} Range: {1, -3, 5, 3} Domain: {1, -3, 5, 3} Range: {9, 8, 7, -5} not a function
Answer:
Domain: {9, 8, 7, -5}Range: {1, -3, 5, 3}Step-by-step explanation:
The function is a special relationship where each input has a single output.
We have C = {(9, 1); (8, -3); (7, 5); (-5, 3)}.
It's a function:
each values of x: 9, 8, 7, -5 has one value of y: 1, -3, 5, 3.
The doimain is set os x: {9, 8, 7, -5}.
The range is set of y: { 1, -3, 5, 3}.
F = {(x, y ) | x + y = 10}.
Domain: {10} Range: {10}

Describe how to translate the graph of g(x) = ln x into the graph of f(x)= ln (-5)+5
Answer:
B
Step-by-step explanation:
We know:
1. Replacing -x into x of an equations reflects the graph on the y-axis
2. If f(x) is a function, then f(x)+a is a vertically translated graph of the original graph, a units up
Looking at the original function of ln x and the transformed graph of ln(-x) +5, we see that we have replaced x with -x, which means it is a reflection across the y-axis.
Also, we have added a five after the function, so that means it is a vertical translation of 5 units up.
Looking at the answer choices, we see that B is the correct answer.

Answer:
a) 0.7486; b) 0.6518; c) No
Step-by-step explanation:
We use z scores to answer these questions. The formula for a z score is
[tex]z=\frac{X-\mu}{\sigma}[/tex]
Our mean, μ, is 44; our standard deviation, σ, is 1.5.
For part a,
We want P(X > 43):
z = (43-44)/1.5 = -1/1.5 = -0.67
Using a z table, we see that the area under the curve to the left of this is 0.2514. However, we want the area to the right; this means we subtract from 1:
1 - 0.2514 = 0.7486
For part b,
We want P(42 ≤ X ≤ 45):
z = (42-44)/1.5 = -2/1.5 = -1.3
z = (45-44)/1.5 = 1/1.5 = 0.67
Using a z table, the area under the curve to the left of z = -1.3 is 0.0968. The area under the curve to the left of z = 0.67 is 0.7486.
The area between them is 0.7486 - 0.0968 = 0.6518.
For part c,
A response of 35 has a z score of
z = (35-44)/1.5 = -9/1.5 = -6
This is 6 standard deviations below the mean. This is more than the amount required to make this an outlier, or an unlikely response.
Consider the inequality -5(x+7) is less than -10. Write an inequality representing the solution for x.
Answer:
x > -8
Step-by-step explanation:
First you distribute the -5 and get
-5x-35 < 10
Then you add 35 to both sides and get
-5x<45
Then dived by NEGATIVE 5 (since it is negative you flip the less than signs to greater than) and get
x> -8

Eight boys and seven girls showed up to one of the team's games. League rules limit each team to 10 players at a time (five girls and five boys) per game. Given this rule, how many combinations of 10 players are there among the 15 boys and girls who showed up at this particular game?
Answer:
1176 Combinations
Step-by-step explanation:
As mentioned in the question, there are total 8 boys and 7 girls.
Our objective is to create a team with 5 boys and girls each.
To select 5 boys out of 8, we will use combination.
=> 8C5 = [tex]\frac{8!}{5!(8-5!)}[/tex]
=> [tex]\frac{8.7.6.5!}{5!.3!}[/tex]
=> [tex]\frac{8.7.6}{6}[/tex]
=> 56
Similarly,
5 girls are selected using 7C5
=> 21
Therefore, the total combination of players are 56 * 21 = 1176
Slaura walks 3/5 mile to school each day. Isaiah walk to school is 3 times as long as Slaura's. How far does Isaiah walk to school each day.
Answer:
1.8 miles
Step-by-step explanation:
3/5 * 3 for the extra mile that he walks
Answer:
1 4/5 miles to school. 3 3/5 miles if you wanted to know to school AND back.
Step-by-step explanation: You would take the 3/5 of a mile that Slaura walks every day and multiply it by 3. Your equation would be 3/5 x 3/1. Your answer for how many miles Isaiah walk to school everyday is 9/5 or 1 4/5 miles. If you wanted to know how many miles Isaiah walked to school AND back, then you would double 1 4/5 miles.

A fair coin is tossed three times in succession. Find the probability if getting exactly one tail
Answer:
If a fair coin is tossed three times, sample = 2^3 = 8 (hhh, hht, hth, thh, htt, tht, tth, ttt) where h=head and t=tail.
Probability of getting one:
Outcomes with one head (h) = 3
P(1 h) = 3/8 = 0.375
The probability of getting exactly one tail when a fair coin is tossed three times in succession is 37.5%.
Explanation:The probability of getting exactly one tail when a fair coin is tossed three times in succession can be found using the binomial probability formula.
Let's denote success as getting a tail and failure as getting ahead. The probability of success, denoted as p, is 0.5 since the coin is fair and has an equal chance of landing on heads or tails. The probability of failure, denoted as q, is also 0.5.
Using the binomial probability formula: P(X = k) = [tex]C(n, k) * p^k * q^(n-k)[/tex], we can calculate the probability as follows:
n = 3 (number of trials) k = 1 (number of tails desired) C(n, k) = C(3, 1) = 3 (number of ways to choose 1 tail from 3 trials)[tex]p^k = 0.5^1[/tex] = 0.5 (probability of getting 1 tail)[tex]q^(n-k) = 0.5^(3-1)[/tex] = 0.25 (probability of getting 2 heads)Plug these values into the formula: P(X = 1) = 3 * 0.5 * 0.25 = 0.375 (or 37.5%)Therefore, the probability of getting exactly one tail when a fair coin is tossed three times in succession is 0.375 or 37.5%.

A simple way to do this is to find 1/4 of the time
To do this, divide by 3:
45/3 = 15
15 minutes is 1/4 of the time
To find the whole time, multiply this value by 4:
15 x 4 = 60
Subtract the time already passed from this:
60 - 45 = 15

A card is drawn from a well-shuffled deck of 52 cards. What is the probability that a red card appears?
1/4
1/2
1/13
0.26
Answer:
P (red) = 1/2
Step-by-step explanation:
It is given that a card is drawn from a well-shuffled deck of 52 cards and we are to find the probability of getting a red card.
We know that there are total 26 red cards in a deck (13 hearts and 13 diamonds).
Therefore, the probability of getting a red card P (red) = [tex] \frac { 2 6 } { 5 2 } [/tex] = 1/2
The probability of drawing a red card from a well-shuffled 52-card deck is 1/2 since half of the cards in the deck are red (26 out of 52)
Explanation:This question pertains to the topic of probability in Mathematics. There are 52 cards in a standard deck, half of which are red (26 red cards: 13 hearts and 13 diamonds). Hence, the probability of drawing a red card is the number of red cards over the total number of cards in the deck.
So, the probability of drawing a red card from a well-shuffled 52-card deck is 26/52, simplified to 1/2. Hence the correct answer from the given choices is 1/2.

Answer:
x = -1, 3
Step-by-step explanation:
so what you need to do is graph each one because that's what the questions ask. One way for you to check your answer is to set the two equations equal to each other.
-x + 5 = x^2 - 3x + 2
you want to end up with one equation and having the equation equal 0. So add x to both sides to cancel out the x on the left side and then subtract 5 from both sides to cancel out the 5 on the left side.
0 = x^2 - 2x - 3
now you factor
0 = (x - 3) (x + 1)
x = -1, 3
Do you think this graph looks more like a quadratic or exponential function? Why do you think so?
Answer:
Exponential Function
Step-by-step explanation:
The y-axis represents the number of Bacteria and x-axis represents the number of hours. If you observe closely you will see that the number of bacteria are doubling after each hour. For example, at time = 4 hours the number of Bacteria were about 50, at time = 5 hours the number of Bacteria were about 100 and at time = 6 hours the number of Bacteria increased to about 200.
This type of behavior is a property of exponential functions where we see a multiplicative rate of change in the values i.e. each value is a multiple of previous value. A rough model for this function would be:
[tex]f(x)=f(0)(2)^{x}[/tex]
Where, f(0) represents the number of bacteria at time = 0 hours i.e. number of Bacteria initially present and "x" represents the number of hours.

Does the equation x2 - 4x + y2 = -3 intersect the x-axis?
Answer:
Yes, twice
Step-by-step explanation:
The equation will intersect the x-axis when y = 0, so we have
x² - 4x = -3 now solve this quadratic for x...
x² - 4x + 3 = 0
factor...
(x - 3)(x - 1) = 0,
so at x = 1 and x = 3, the function crosses the x-axis
See the graph below
Yes, because the center is on the x-axis, the circle will intersect 2 times, at x=1 and at x=3
