In order to find the area of composite figures and trapezoids, you should decompose the figure into simple shapes, calculate each of their areas, and then sum these areas up. For trapezoids, use the formula 1/2 (sum of the bases) x height.
Explanation:The question provides a complex description of a figure, but it seems this is a mathematical problem dealing with areas of trapezoids and composite figures. It can be inferred that you need to maneuver pieces to cover the shaded area of a figure. Here's a general way to approach it:
Decompose the figure: Break down the complex figure into simple shapes such as rectangles, squares, triangles etc. Calculate the areas: Use the appropriate formulas to calculate the areas of these simpler shapes. Sum up the areas: Add the areas of the individual shapes to get the total area of the composite figure.
For the trapezoids, remember that the area of a trapezoid is given by 1/2 (sum of the bases) x (height).

A restaurant noted what type of food its customers purchased last week. Here are the results:
Burger
Fries
15%
55%
10%
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.
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

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.

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.

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.

Matt has $900 in a checking account, has $15,000 in investments, owns an
$8000 car, and owns a $30,000 house. What is the total value of his large
assets
Answers
The total value of Matt's large assets, which include his investments, car, and house, adds up to $53,000.
Explanation: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.
Investments: $15,000Car: $8,000House: $30,000We 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.

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

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.

26 out of 48 books are small. What percentage of the books are small?
Answers
Answer:
54.16%
Step-by-step explanation:
The percentage of books that are some is 54.16 %
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%
