the number of people who attended the spring festival is 799 more than 8 thousands. how many people attended the festival?
Answers
In this question, we are given the information about total number of people but in word equation.
We are given that, 799 more from 8 thousand attend the festival.
When we are given more, we add the number to the number from which it is more.
Here, we will add 799 to 8,000 in order to calculate total number of people who attended the festival
Thus, total number of people who attended the festival = 8,000 people + 799 people = 8,799 people.

triangle ABC is similar to Triangle XYZ.
AB=9.7, BC=9.6, AC=15.1
YZ=118.8, Find XZ
Answers
Since the triangles are similar, the ratio of their angles is the same. This means the ratio of BC to YZ will be the same as the ratio of AC to XZ; using this to set up a proportion,
9.6/118.8 = 15.1/x
Cross multiply:
9.6*x = 118.8(15.1)
9.6x = 1793.88
Divide both sides by 9.6:
9.6x/9.6 = 1793.88/9.6
x = 186.8625

A motorboat covers the distance from one pier to the other pier in 4 hours and the way back in 5 hours. What is the speed of the boat in still water, if it covers 70 km with the current in 3.5 hours?
(its not 20 i tried)
Answers
r + c = speed with current
r - c = speed against current
3.5(r + c) = 70
r + c = 20
c = 20 - r
4(r + c) = distance from pier to pier
5(r - c) = distance from pier to pier
4(r + c) = 5(r - c)
4(r + 20 - r) = 5(r - 20 + r)
80 = 10r - 100
180 = 10r
18 = r
The speed in still water is 18 km/hour

A. 6 was not multiplied by m
B. Incorrect sign was used for the first term
C. Incorrect sign was used for the second term
D. 6 was not multiplied by 3
Answers
Look at them one at a time
Choice A
The result of multiplying 6 and m together (which is what you are supposed to do is 6m). This step is correct.
Choice B
There are no minus signs anywhere, either outside or inside the brackets, B is incorrect. Minus signs cannot be manufactured out of thin air. You need a reason.
Choice C
Same as B.
D is the correct answer. Both sides of a plus or minus sign have to be multiplied by what is outside the brackets. The plus sign cannot be destroyed unless you started out with something like
6 ( 4m + 3m) which = 24m + 18m = 42m But you could have combined like terms in the beginning.
6 * 7m = 42m

The median and interquartile range of a set of data is shown. Write a set of data consisting of seven values for the pair of measures.
Median: 5 Interquartile Range: 5
Answers
If the IQR is 5, we then know that the difference between y and r is 5.
Let's find the 1st and 3rd quartiles. Focusing on the 1st 3 numbers, we see that the 1st quadrant is y; focusing on the last 3 numbers, we see that the 3rd quadrant is r. The IQR is r-y = 5. Just supposing that y were 4, r would be 9:
x 4 y 5 q 9 s
We could arbitrarily let x = 3, y = 4, q = 5 and s = 9: 3 4 4 5 5 9 9.
We must check this!
What is the median? Since there are 7 numbers here, we take the middle number (5) as the median. This agrees with the problem statement.
Next, we find Q1 and Q3. Q1 is the number between 3 and the 2nd 4, and is 4. Q3 is 4+5, or 9, because the IQR is 5. This agrees with the problem statement.

Mr. McClellan compared the weights (in pounds) of pairs of elk antlers dropped at Mount St Helens NVM and Rocky Mountain NP. He tabulated them in the following data table.
Weight of elk antler pairs at Mount St Helens NVM:
{34, 34, 30, 30, 30, 28, 28, 26}
Weight of elk antler pairs at Rocky Mountain NP:
{40, 38, 36, 36, 36, 36, 34, 32}
(a) Create a line plot for each data set.
(b) Calculate the mean and MAD for each area of collection.
(c) Calculate the means-to-MAD ratio for the two areas of collection.
(d) What inference can be made about the areas in regard to weight of dropped elk antlers? Explain
Answers
B) In order to calculate the mean, you have to sum all the values and divide it by the number of values:
m(MSH) = (34 + 34 + 30 + 30 + 30 + 28 + 28 + 26) ÷ 8
= 240 ÷ 8
= 30
m(RM) = (40 + 38 + 36 + 36 + 36 + 36 + 34 + 32) ÷ 8
= 288 ÷ 8
= 36
In order to calculate the mean absolute deviation (MAD), you need to calculate the absolute values from the mean, sum them up and divide it by the number of values; the absolute values of the difference from the mean are:
MSH = {|34-30|, |34-30|, |30-30|, |30-30|, |30-30|, |28-30|, |28-30|, |26-30|}
= {4, 4, 0, 0, 0, 2, 2, 4}
RM = {|40-36|, |38-36|, |36-36|, |36-36|, |36-36|, |36-36|, |34-36|, |32-36|}
= {4, 2, 0, 0, 0, 0, 2, 4}
Therefore,
MAD(MSH) = (4 + 4 + 0 + 0 + 0 + 2 + 2 + 4) ÷ 8
= 16 ÷ 8
= 2
MAD(RM) = (4 + 2 + 0 + 0 + 0 + 0 + 2 + 4) ÷ 8
= 12 ÷ 8
= 1.5
C) In order to calculate the mean-to-MAD ratio, you need to simply divide the mean by the MAD:
r(MSH) = 30 ÷ 2 = 15
r(RM) = 36 ÷ 1.5 = 24
D) We can say that in Mount St Helens NVM elk antlers pairs are lighter but with a bigger variability (which means that they tend to be weight differently from each other), while in Rocky Mountain NP elk antlers pairs are heavier, but with less variability (which means that they tend to be similar to each other).
A) The two line plots are attached.
B) In order to calculate the mean, you have to sum all the values and divide it by the number of values:
m(MSH) = (34 + 34 + 30 + 30 + 30 + 28 + 28 + 26) ÷ 8
= 240 ÷ 8
= 30
m(RM) = (40 + 38 + 36 + 36 + 36 + 36 + 34 + 32) ÷ 8
= 288 ÷ 8
= 36
In order to calculate the mean absolute deviation (MAD), you need to calculate the absolute values from the mean, sum them up and divide it by the number of values; the absolute values of the difference from the mean are:
MSH = {|34-30|, |34-30|, |30-30|, |30-30|, |30-30|, |28-30|, |28-30|, |26-30|}
= {4, 4, 0, 0, 0, 2, 2, 4}
RM = {|40-36|, |38-36|, |36-36|, |36-36|, |36-36|, |36-36|, |34-36|, |32-36|}
= {4, 2, 0, 0, 0, 0, 2, 4}
Therefore,
MAD(MSH) = (4 + 4 + 0 + 0 + 0 + 2 + 2 + 4) ÷ 8
= 16 ÷ 8
= 2
MAD(RM) = (4 + 2 + 0 + 0 + 0 + 0 + 2 + 4) ÷ 8
= 12 ÷ 8
= 1.5
C) In order to calculate the mean-to-MAD ratio, you need to simply divide the mean by the MAD:
r(MSH) = 30 ÷ 2 = 15
r(RM) = 36 ÷ 1.5 = 24
D) We can say that in Mount St Helens NVM elk antlers pairs are lighter but with a bigger variability (which means that they tend to be weight differently from each other), while in Rocky Mountain NP elk antlers pairs are heavier, but with less variability (which means that they tend to be similar to each other).

A small Learning Center holds 24 less students than the larger Learning Center. Together the learning centers hold seventy-two students. How many students does each Learning Center hold?
Answers
L=Large
72=(L-24)+s
48=L+s
By this point, the “-24” no longer affects the equation. L=s for the purpose of division.
48/2
24=s
Now we know s=24.
The “-24” is now important in finding the value of L. We find the inverse of “-24”, +24.
s+24=48
s= 24 students
L= 48 students
The larger Learning Center can hold 48 students and the smaller Learning Center can hold 24 students.
Explanation:The key to solving this problem is to first express it as two linear equations. Let's denote the number of students the small Learning Center holds as S and the number of students the larger Learning Center holds as L.
The problem provides us with two facts:
The small Learning Center holds 24 less students than the larger one, we can express this as: S = L - 24.Together, both Learning Centers hold seventy-two students, so we can express this as: S + L = 72.Now, we can solve these two equations simultaneously.
Substitute S from the first equation into the second: (L - 24) + L = 72, simplify to: 2L = 96
Thus, L = 48. This means the larger Learning Center can hold 48 students. Substitute L=48 into our first equation to find S: S = 48 - 24 = 24. So, the small Learning Center can hold 24 students.

what number must you add to complete the square? x2-20x=17
A. 100
B. -10
C.-100
D. 10
Answers
Answer:
The number is 100
A is correct
Step-by-step explanation:
Given: [tex]x^2-20x=17[/tex]
We need to make completing square at left side.
Rule: We add a number " take half of the coefficient of x and then square it"
Coefficient of x = 20
Half of 20 = 10
Square of 10 = 100
So, we will add 100 both sides make completing square.
Now we make completing square to add 100
[tex]x^2-20x=17[/tex]
Add 100 both sides
[tex]x^2-20x+100=17+100[/tex]
Now we will factor left side perfect square
[tex]a^2-2ab+b^2=(a-b)^2[/tex]
[tex](x-10)^2=117[/tex]
[tex](x-10)^2[/tex] is completing square or perfect square.
Hence, The number is 100

The preventable nature of deaths caused by impaired driving, emphasizing the impact of alcohol and other risky behaviors on driving safety.
Explanation:
Each day in the United States, over 8 people are killed and 1,161 injured in crashes reported to involve a distracted driver, highlighting a significant public health concern. There is a noted problem with young drivers getting into serious automobile accidents, contributing to many preventable deaths.
It has been estimated that 35 percent of all U.S. early deaths in 2000 could have been avoided by changing just three behaviors, with alcohol being a significant contributing factor to risky behavior on the roads.
In 2014, alcohol-impaired driving fatalities accounted for 9,967 deaths, which is 31% of overall driving fatalities, underscoring the critical need for improved driving safety measures and individual behavior changes to reduce these numbers.
