Answer:
option D 41
Step-by-step explanation:
since ∠N = ∠L
this means that MN = ML (sides opposite to equal angles are equal)
thus
3x + 1 = 5x - 7
1 + 7 = 5x - 3x
8 = 2x
8/2 = x = 4
inserting values
3*4 + 1= 13
4*4-1 =15
5*4-7 = 13
adding all
13 + 13+ 15 = 41
option D 41
Identify all the functions that have a greater rate of change and the function represented in the graph
A y= 2x+7
B y=1.5x+ 1
C y=0.5x-5
D y=2.5x-20
E y=3x+12
F y=x +7
The equation with the greater rate of change is y = 3x + 12, which has a rate of change of 3.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the y intercept.
Given the equations, the equation with the greater rate of change is y = 3x + 12, which has a rate of change of 3.

Answer: The flagpole is about 22.3 feet tall.
This is roughly the size of a two story building, assuming each floor is 10 feet or so.
Since this height is under 25 ft, this flagpole is in compliance with the regulation.
=====================================================
Work Shown:
The horizontal leg of the triangle is 36 ft. This is the adjacent leg to the reference angle 25 degrees.
The vertical leg of the triangle is x-5.5, and this leg is the opposite side to the reference angle 25 degrees.
Use the tangent rule to connect the opposite and adjacent sides.
Solve for x.
tan(angle) = opposite/adjacent
tan(25) = (x-5.5)/36
36*tan(25) = x-5.5
x-5.5 = 36*tan(25)
x = 36*tan(25)+5.5
x = 22.28707569358
x = 22.3 ft is the approximate height of the flagpole
Make sure your calculator is in degree mode.
The height is not over 25 ft, so this flagpole meets the requirements.

A person draws a card from a hat. Each card is one color, with the following probabilities of being drawn: 1/25 for green, 1/15 for blue, 1/20 for pink, and 1/5 for red. What is the probability of pulling a red or pink card, written as a reduced fraction?
Answer:
Step-by-step explanation:
0.2(red) + 0.05(pink)
=0.25
=1/4
ALLWAYS REMEMBER OR MEANS ADD AND AND MEANS MULTIPLY
The probability of pulling a red card or a pink card is [tex]\frac{1}{4}[/tex].
Probability:The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.Step-by-Step Solution -To remember -
'OR' means add.'AND' means multiply. [tex]0.2(red)+0.05(pink)\\= 0.25\\=\frac{1}{4}[/tex]Therefore, the probability of pulling a red card or a pink card is [tex]\frac{1}{4}[/tex].

Leo found an orange caterpillar and a green caterpillar in his backyard. The green caterpillar was 3 1/3 inches long and the orange caterpillar was 1 2/3 inches long. How much longer was the green caterpillar than the orange caterpillar?
Answer:
the green caterpillar is 5/3 inches or 1 2/3 inches longer than the orange caterpillar
Step-by-step explanation:
Subtract 3 1/3 by 1 2/3
Answer:
1 2/3 in longer
Step-by-step explanation:
Green: 3 1/3 = 10/3 (Multiply the whole number by the denominator and add that to the numerator for the new numerator).
Orange: 1 2/3 = 5/3
Difference: 10/3 - 5/3 = 5/3 (When subtracting fractions with the same denominators, just subtract the numerators and leave the denominators the same).
5/3 = 1 2/3 (To convert to a mixed number, divide numerator by denominator. The remainder is the new numerator and the quotient is the whole number).

Laura has 160 pounds of green beans at her vegetable stand. If she sells 10 pounds of green beans every hour, what is the percent decrease in green beans after 3 hours?
A
18.75%
B
81.25%
C
23.07%
D
16%
Given:
Laura has 160 pounds of green beans at her vegetable stand.
She sells 10 pounds of green beans every hour.
To find:
The percent decrease in green beans after 3 hours.
Solution:
We have,
Beans sold in 1 hour = 10 pounds
So, Beans sold in 3 hours = 30 pounds
Decrease in green beans after 3 hours is 30 pounds.
Now,
[tex]\%\text{Decrease}=\dfrac{\text{Decrease in green beans after 3 hours }}{\text{Initial amount of green beans}}\times 100[/tex]
[tex]\%\text{Decrease in green beans after 3 hours}=\dfrac{30}{160}\times 100[/tex]
[tex]\%\text{Decrease in green beans after 3 hours}=\dfrac{300}{16}[/tex]
[tex]\%\text{Decrease in green beans after 3 hours}=18.75\%[/tex]
Therefore, the correct option is A.

After complaining about the bonus plans, you wake up
on Conglomo's private island, where you break big rocks
into smaller rocks for $10 a day. There are 999 other
employees on the island, 998 of whom get paid the same
way you do. The last employee is your overseer, who is
paid $10 million per year.
What is the mean and median income for
workers on Super Happy Fun Island?
Which method of describing central tendency
better represents this data? Why?
Answers:
mean annual income = $13,646.35
median annual income = $3,650
The median is a better measure of center
=======================================================
Explanation:
If you earn $10 a day, and do so for 365 days, then you earn 365*10 = 3650 dollars per year.
If there are 999 employees earning this amount, then the amount earned is 999*3650 = 3,646,350
Add on the 10,000,000 to get
10,000,000+3,646,350 = 13,646,350
The total amount earned is $13,646,350
Divide this over the 1000 people (999 workers + 1 boss)
We get: (13,646,350)/(1,000) = 13,646.35
The mean is annual income is $13,646.35
--------------------------------
The median is the middle most value. If you list out the pay amounts of just the workers, you'll get the list:
{3650, 3650, 3650, ..., 3650}
We will have 999 copies of 3650 listed out. You don't have to list all 999 of them. Just a few is a good start. The three dots indicate the pattern goes on until we reach the 999th item.
If we then tack on the overseer's pay, then we have the list
{3650, 3650, 3650, ..., 3650, 10 million}
I'm using "million" instead of the digits to avoid using commas here.
The middle won't change due to one item being tacked onto the end. The middle is going to be 3650 either due to it being part of the set, or we find the midpoint between 3650 and 3650, which averages out to 3650.
The median income is $3,650
-----------------------------------
The median income is the better measure of center because it represents where the workers are instead of some distant "midpoint" between the workers and the boss. No person is making $13,646.35 a year. They are either making $3,650 or they are making $10,000,000. There's nothing in between. So it's better go lean toward the larger group when deciding where the center should go. Think of it like a balance beam or a see-saw.
As you can see the median is not affected by outliers. We can change the "ten million" to something like "a hundred million" and the median would still be the same. I recommend you compute the mean if the overseer earns 100 million dollars, and you'll find the mean will increase dramatically. However, the median will stay where it's at. The only time the median will change is if we introduce elements that are somewhere around (either higher or lower) than 3650, and these values are close to 3650. But this won't change the center very much compared to the drastic changes the mean undergoes due to such a large outlier.
The general rule of thumb is: a large outlier to the right pulls the mean to the right. An outlier to the left pulls the mean to the left. In this case, the mean is pulled to the right. The data is skewed to the right (or positively skewed).
So again, the conclusion is that the median is the better measure of center.
