= 20

Answer:

3m^2+3

Step-by-step explanation:

Step 1:  First you have your equation or something.

3m (m+1)

Step 2: You multiply the parenthesis with the number.

Step 3: Then 3m to the parenthesis if you have 3m and m will convert to m^2.

Step 4: Your answer would be 3m^2+3

Answer:

So you solve it .... 3m^2+ 3m

Step-by-step explanation:

Answer:

1. There are a fixed number of trials

2. There are two outcomes: success (getting a 4) and failure (not getting a 4)

3. You know the probability of success and it is the same for each trial

4. You are looking for the probability of getting a 4 exactly 3 out of 10 times. When you're looking for the probability of getting exactly x number of successes in n trials, that is a binomial probability distribution.

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.

  It is a solution, one of an infinite number of solutions.

Step-by-step explanation:

You can check to see if the given point is in the solution set:

  4(-4) +5(4) = -16 +20 = 4 > -6 . . . . yes

  -2(-4) +7(4) = 8 +28 = 36 > 20 . . . yes

The offered point satisfies both inequalities, so is in the solution set. It is not the solution, but is one of an infinite number of solutions.

The total value of Matt's large assets, which include his investments, car, and house, adds up to $53,000.

The student is asking about calculating the total value of large assets that Matt owns. To find this, we add up the value of the investment, car, and house as these are considered large assets. The checking account is generally not included in large assets, as it is considered liquid cash rather than an asset of substantial value like property or investments.

We calculate the sum of these amounts to get the total value of Matt's large assets:

$15,000 + $8,000 + $30,000 = $53,000

Therefore, the total value of Matt's large assets is $53,000.

Step-by-step explanation:

Step-by-step explanation:

It is given that, Steve is making a circular shield with a radius of 11 inches for a school play. We need to find the length of cardboard he need to make the outer border of the shield. It means that we need to find the circumference of the circular shield of radius 11 inches.

So,

[tex]C=2\pi r\\\\C=2\times 3.14\times 11\\\\C=69.08\ \text{inches}[/tex]

So, he will need 69.08 inches of cardboard to make the outer border of the shield.

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.

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.

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

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.

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.

In order to find that answer you would have to calculate the total number of small books (26) over the total number of all of the books (48).

The equation would be 26/48=0.5416 however Multiply that answer by 100 and you would get 54.16% and if you want to round to the nearest whole number it would just be 54%

Answer:

B

Step-by-step explanation:

The polynomial function shown in the graph is of even degree and has 2 real zeroes.

The polynomial function shown in the graph appears to have 2 real zeroes. Since the degree of the polynomial cannot be determined from the graph alone, we cannot determine if it is of odd or even degree. Therefore, option A) and B) can be eliminated. Thus, the correct answer is C) It is of even degree and has 2 real zeroes.

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
