Answer:
P(M) + P(P)
Step-by-step explanation:
In general, for two mutually exclusive events A and B, P(A occurs or B occurs) = P(A or B) = P(A) + P(B)
Thus, P(M or P) = P(M) + P(P)

Thirty seventh graders each took a random sample of 10 middle school students and asked each student whether or not he likes pop music. Then, they calculated the proportion of students who like pop music for each sample. The dot plot below shows the distribution of the sample proportions.
Based on the dot plot, do you think the proportion of the middle school students at this school who like pop music is 0.5? Explain why or why not.

What is the value of x+y?
Eight grade math
Hello! The value of x+y is 12
Make sure to read an explanation so you can understand the solution better.
Any questions about the answer and explanation can be asked through comments.
Step-by-step explanation:
We can simply solve the system of equations by substituting x = 3y in the first equation
[tex] \large{2x + 2y = 24} \\ \large{2(3y) + 2y = 24} \\ \large{6y + 2y = 24} \\ \large{8y = 24} \\ \large{y = 3}[/tex]
Therefore, the value of y is 3. Then we substitute the value of y in x = 3y.
[tex] \large{x = 3y} \\ \large{x = 3(3)} \\ \large{x = 9}[/tex]
Therefore, the value of x is 9.
Since you want to find x+y, simply add 9 and 3 as we get 12.
Therefore x+y = 12.
Sixty percent of students in your school own a bike. Of a sample of students in your school, the ratio of students who own a bike to students who do not own a bike is 4:10. Does the sample closely estimate the percentage of students in your school who own a bike?
Answer:
No, because 4:10 means 4 out of 14 people own a bike this is roughly 28.5%. This is not close to the 60% of people who own a bike.

A hotel survey showed that nearly 30% of the guests staying at the hotel were there for personal reasons. The remainder of the guests were at the hotel on business.
Use the table of randomly generated letters to answer the questions about this scenario. The letter P represents personal reasons, and B represents business reasons.
BBB PBB BPB PPB BBP
BBP PBB PPB PBB BBP
BBP BPB BBB BBB BBB
PPB BPB PBP BPB BBP
BPB PBP PPB PBB BBB
Based on this data, the estimated probability that exactly two of the three guests randomly picked were not there for personal reasons is .
The estimated probability that it takes at least four guests to find one who is staying for personal reasons is .
I'm not entirely sure so if I get this wrong please don't be mad.
The list has 26 people there for personal reasons, and 49 people there for business reasons. Sorry if I'm wrong.

Skewed right.

Find the area of the complex figure.
A figure has 8 sides; all sides meet at right angles. The left-most vertical side measures 31 meters. The lower most horizontal side measures 69 meters. The right-most vertical side measures 31 meters. The upper right horizontal side measures 23 meters. The middle horizontal side measures 23 meters. The upper middle left vertical side measures 12 meters.
Answer:
The answer would be 2691 meters.
Step-by-step explanation:
When looking at the figure, since you know the length of all of the sides you can easily cut it into three simpler rectangles by extending the line of 23 meters out to either side.
This gives us three rectangles by the measures of 23 by 12, 23 by 12, and 31 by 69.
In order to calculate area you do equation A=LxW
In this case, Area=(23) x (12)
This will get you the answer 276 meters.
Do this again for the other rectangle that measures 23 by 12, and add the two areas together.
This gives you 552 meters.
To find the area of the remaining triangle, once again do A=LxW
Area=(31) x (69)
This will give you 2139 meters.
To find the total area of the figure, add the two areas that we have already found out together,
522+2139
and you get your answer of 2691 meters.

Which are equivalent ratios to 3:4?
Check all that are true.
6:8
15:20
9:12
9:15
16:20
Answer:
6:8
15:20
9:12
How?
3:4*2=6:8
3:4*5=15:20
3:4*3=9:12
The equivalent ratio to the given to 3:4 are 6:8, 15:20 and 9:12
How to obtain real measurements from the ratio of two measurements?Suppose the real measurements were "a" and "b"
Then their ratio will be formed as
[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]
where is a common factor (not 1)
This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator. Thus, a = px, b = qx
We are given the ratio as; 3:4
3: 4 x 2 = 6 : 8
3: 4 x 5 = 15 : 20
3: 4 x 3 = 9 : 12
Therefore, the equivalent ratio to the given to 3:4 are 6:8, 15:20 and 9:12

Step-by-step explanation:
A rectangular barn measuring 14 feet b 10 feet is located in one corder of a fenced area. Robert ties his cow to the corner of the barn so the animal can graze anywhere within the circular area outside the barn and fence. If the cow is tied with a 24 ft rope, approximately how much grazing area does the cow have?
If when the cow is tied with a 24 ft rope, So approximately, The Cow has 1,356.48 Ft of grazing area.
Calculation of Circular area
For this situation, you would be translating for the area of 3/4 of a circle with the radius being 24ft.
So the area of a circle is a is = PI R squared so plugin 3.14(24) squared order of functions says to square first so 24 squared is 576.
Then PI or 3.14 times 576 equals 1808.64
Now because it is exclusively 3/4 of a circle you will reproduce the response by 3/4 which is 1,356.48 ft.
Therefore, The Cow has 1,356.48 Ft of grazing area.
