What effect will multiplying by 3 have on f(x)?
Answers
Answer:For a positive value k, the graph of y=kf(x) is obtained from the graph of y=f(x) by scaling in the vertical direction. In coordinates, if (x0,y0) is on the graph of y=f(x), then that point moves to (x0,ky0) on the graph of y=kf(x). Any point on the x-axis remains fixed (as then y=0). When k>1, the graph is stretched vertically (away from the x-axis), while if 0<k<1, the graph is compressed vertically (toward the x-axis).
Another way to think about this: The graph of y=kf(x) is exactly the same as the graph of y=f(x) if the y-axis is scaled so that 1 is relabeled k, 2↦2k, −1↦−k, etc.

Answers
Answer: Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.
Step-by-step explanation:
4x - x + 5 = 8 - 3x - 3
Combine like terms
4x - x + 5 = 5 - 3x
Subtract x from 4x
3x + 5 = 5 - 3x
Add -3x to both sides
6x + 5 = 5
Subtract 5 from each side
6x = 0
Divide by 6
x = 0
Put 0 into the equation
4(0) - 0 + 5 = 8 - 3(0) - 3
Multiply
0 - 0 + 5 = 8 - 0 - 3

Step-by-step explanation:
the answer is 20
The angles are supplementary angles. Then the value of the variable 'x' will be 20.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Angle 7x and angle (x + 20) is the supplementary angles. Then the equation is given as,
7x + x + 20 = 180
Simplify the equation, then we have
7x + x + 20 = 180
8x = 160
x = 20
The angles are supplementary angles. Then the value of the variable 'x' will be 20.

In this sample, are the events "burger" and "fries" mutually exclusive?
Answers
Answer:
No, they are not mutually exclusive because a customer can purchase a burger and fries together.
Step-by-step explanation:
Mutually exclusive events are events that cannot occur at the same time, e.g. I cannot sleep while running. In the case of a restaurant, you could consider purchasing pizza and burgers as mutually exclusive since most people would only purchase one of them (unless they eat a lot). But burgers and fries are not mutually exclusive because people can purchase them together.

Answers
Answer:
Which plant was taller when Nara got the plants? C. They were equally tall
Which plant grew faster? B. The second plant
Step-by-step explanation:
Slope of the first plant :
m = (y2 - y1)/(x2- x1)
m = (36 - 34)/(15 - 10) = 0.4
y-intercept of the first plant :
y = m*x + b
b = y1 - m*x1
b = 34 - 0.4*10 = 30
From the picture we can see that the y-intercept of the second plant is 30 cm
Y-intercept represents plant heights when Nara got the plants; then they were equally tall
From the picture we can see that second plant grew 2 cm in 2 days; then its slope is 2/2 = 1
Slope measures how fast each plant grew; then the second plant grew faster
According to a recent New York Times poll, 25% of the public have responded to a telephone call-in
poll. Based upon this information, what is the probability that exactly two people out of a randomly
chosen group of five people have responded to a telephone call-in poll? Round your answer to the
nearest thousandth (3 decimal places).
Answers
Answer:
Probability that exactly two people out of a randomly chosen group of five people have responded to a telephone call-in poll is 0.264.
Step-by-step explanation:
We are given that according to a recent New York Times poll, 25% of the public have responded to a telephone call-in poll.
Also, five people have people have been randomly selected.
The above situation can be represented through binomial distribution;
[tex]P(X = r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r};x=0,1,2,3,.......[/tex]
where, n = number trials (samples) taken = 5 people
r = number of success = exactly two
p = probability of success which in our question is probability that
public have responded to a telephone call-in poll, i.e; p = 25%
Let X = Number of people who have responded to a telephone call-in poll
So, X ~ Binom(n = 5, p = 0.25)
Now, probability that exactly two people out of group of five people have responded to a telephone call-in poll is given by = P(X = 2)
P(X = 2) = [tex]\binom{5}{2} \times 0.25^{2} \times (1-0.25)^{5-2}[/tex]
= [tex]10 \times 0.25^{2} \times 0.75^{3}[/tex]
= 0.264
Therefore, the probability that exactly two people out of a randomly chosen group of five people have responded to a telephone call-in poll is 0.264.
The probability of exactly two people responding is 0.262 in this case.
Explanation:To calculate the probability that exactly two people out of a randomly chosen group of five people have responded to a telephone call-in poll, we need to use the binomial distribution formula. The formula is: P(X=k) = C(n, k) * p^k * (1-p)^(n-k), where P(X=k) is the probability that k people responded, C(n, k) is the number of ways to choose k people out of n, p is the probability of success (25% in this case), and n is the number of trials (5 in this case).
Plugging in the values: P(X=2) = C(5, 2) * (0.25)^2 * (0.75)^(5-2)
Simplifying and calculating, we get: P(X=2) = 10 * 0.0625 * 0.421875 = 0.26172
Rounding to the nearest thousandth, the probability that exactly two people out of a randomly chosen group of five people have responded to a telephone call-in poll is approximately 0.262.

Find the equation of the line that has slope of 7 and passes through the point (-9,2).
Answers
Answer:
y=7x+65
Step-by-step explanation:
You want to find the equation for a line that passes through the point (-9,2) and has a slope of 7.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was 7. So you can right away fill in the equation for a line somewhat to read:
y=7x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(-9,2). When x of the line is -9, y of the line must be 2.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the 7 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-9,2).
So, why not plug in for x the number -9 and for y the number 2? This will allow us to solve for b for the particular line that passes through the point you gave!.
(-9,2). y=mx+b or 2=7 × -9+b, or solving for b: b=2-(7)(-9). b=65.
The equation of the line that passes through the point (-9,2) with a slope of 7
is
y=7x+65

On average it takes Erika about minutes per mile less than Rita
Answers
Answer:
On average, Erika is much slower than Rita by 1 minute.
Step-by-step explanation:
There are two sets of data: Erika's and Rita's. Now, we have to find the average values for each of both and compare them. I would assume that the order of the presentation of data points is alternating, first for Erika followed by Rita. To illustrate what I mean, let's say in Day 1, Erika's time is 20 and Rita's time is 21.25. In Day 2, Erika's time is 21.5 and Rita's is 24.75. And so on and so forth. The complete tabulation is shown in the picture.
Erika's average = (20+21.5+22.75+23.25+20.25)/5 = 21.55
Rita's average = (21.25+24.75+23+23+20.75)/5 = 22.55
On average, Erika is much slower than Rita by 1 minute.
The table below shows the ages of houses to the nearest year in a neighborhood. Using the age of the houses as the random variable, X, which graph shows the probability distribution, PX(x), of a randomly chosen house? HURRYYYYYYY!!!!!
Answers
Answer:
Find the probability distribution by dividing the number of houses in each category by the total number of houses. We find that Graph A most accurately shows the distribution.
Step-by-step explanation:
Let's start by finding the probability of randomly selecting a house in each category. To find the probability, divide the number of houses in the category by the total number of houses.
The total number of houses is 15 + 20 + 25 + 30 = 90. The number of 1 y/o houses is 15. Dividing these two numbers, we get 15/90 = 0.167
Make the same calculation for the other ages:
2 y/o: 20/90 = 0.222
3 y/0: 25/90 = 0.278
4 y/o: 30/90 = 0.333
Now, look at the graphs to determine which most closely matches these calculations. (Note: make sure to look closely at the axis.) That graph is A.

D) 196 people per square kilometer
Answers
Answer:
C) 510 people per square kilometer
Step-by-step explanation:
Population Density = Population/Area
= 2,550,000/5000
= 2,550/5
= 510 people per square kilometer
The approximate population density of Miami-Dade County in 2011 was 510 people per square kilometer.
What is population density?Population density is a measurement of population per unit of land area.
Given that, in 2011,Miami-Dade County had a population of about 2.55 million people and covered an area of about 5000 square kilometers.
We need to find the population density of Miami-Dade County in 2011
So,
To calculate the population density, you will divide the population by the size of the area.
Thus, Population Density = Number of People/Land Area.
The unit of land area should be square miles or square kilometers.
Therefore,
= 2,550,000/5000
= 2,550/5
= 510 people per square kilometer
Hence, the approximate population density of Miami-Dade County in 2011 was 510 people per square kilometer.
