Answer:
5
Step-by-step explanation:
factors of 20:
1, 2, 4, 5, 10, 20
factors of 10:
1, 2, 5, 10
factors of 25:
1, 5, 25
as you can see from the factor list of each number, 5 is the higest common factor.
Maurice's teacher asked him to compare the mean and median of the data distribution explain and correct Maurice's error in comparing the mean and the median
The first part where he mentions "The distribution is skewed right" is correct. The tail on the right hand side is pulled longer than it should be, or longer compared to the left tail. "Right skew" or "skewed right" is the same as "positively skewed". They all mean the same thing.
The portion where Maurice says "This implies that the mean is less than the median" is incorrect. This is where his error is located. The reason for the error is because it should be "The mean is greater than the median" when we have right-skewed data like this.
Here's one example to see why this is the case. Consider the distribution {1,2,3,4,5}. We can see that the median is 3 since it's directly in the center. The mean is also 3 since we add up all the values and divide by 5. Symmetric data has mean = median. Now, we'll replace the '5' with something much larger to get a large outlier. Let's say we have the set {1,2,3,4,55}. The median is still 3. The outlier doesn't pull on the median. However, the mean has changed and it is (1+2+3+4+55)/5 = 65/5 = 13. The mean went from 3 to 13. Therefore, mean > median here. The mean is affected by outliers. Think of it like the outlier is pulling on the mean in a sort of magnetic way. This outlier makes the mean larger than it should be. If the outlier is extreme enough, then it sometimes makes sense to consider the trimmed mean as opposed to the regular arithmetic mean. The trimmed mean is the mean of the main cluster of values ignoring the outlier(s).
-----------------------
To recap:
If we have right skewed data, then mean > median
As you can probably guess, if we had left-skewed data, then mean < median. In symmetric data, mean = median.

Step-by-step explanation:
Employees at the ACME paper bag corporation have two fast food restaurant chains located next to the corporate parking lot: Carl's Jr. and Wendy's. Due to time restrictions the ACME employees eat their lunches either at Carl's Jr. or Wendy's and nowhere else. If today an employee eats lunch at Wendy's, then tomorrow the probability they'll eat lunch at Wendy's is 10% otherwise they'll eat lunch at Carl's Jr. If today an employee eats lunch at Carl's Jr., then tomorrow the probability they'll eat lunch at Carl's Jr. is 40% otherwise they'll eat lunch at Wendy's. If on Monday an employee eats lunch at Carl's Jr. what is the probability they'll eat lunch at Carl's Jr. Wednesday?
Answer:
0.7 = 70% probability they'll eat lunch at Carl's Jr. Wednesday.
Step-by-step explanation:
We have that:
Carl's Jr on Monday.
On Tuesday:
40% probability of Carl's Junior.
100 - 40 = 60% probability of Wendy's.
On Wednesday:
If on Tuesday it was on Carl's Junior, 40% probability of Carl's Junior on Wednesday.
In on Tuesday it was on Wendy's, 100 - 10 = 90% probability of Carl's Junior on Wednesday.
What is the probability they'll eat lunch at Carl's Jr. Wednesday?
[tex]p = 0.4*0.4 + 0.6*0.9 = 0.7[/tex]
0.7 = 70% probability they'll eat lunch at Carl's Jr. Wednesday.

Why do you think adding and subtracting polynomial expressions is like adding and subtracting
expressions?
Answer:
Polynomials are closed under addition and subtraction, which is fancy mathspeak that means that whenever we add or subtract two polynomials, we always get another polynomial. In that way, they behave a lot like the numbers you're probably already familiar with. Adding and subtracting:
Two integers gives you another integerTwo rational numbers gives you another rational numberTwo real numbers gives you another real numberAnd it works the same with polynomials!
An animal shelter has 34 dogs and 62 cats. Find the ratio of dogs to cats
Answer:
17 : 31
Step-by-step explanation:
[tex]\frac{34}{62} =\frac{17}{31}[/tex]
Answer:
17:31
Step-by-step explanation:
We can simplify the ratio 34 : 62 by dividing both terms by the greatest common factor (GCF).
The GCF of 34 and 62 is 2.
Divide both terms by 2.
34 ÷ 2 = 17
62 ÷ 2 = 31
Therefore:
34 : 62 = 17 : 31

The diagonals of square ABCD intersect at point E. If BE = 2x + 1, and AC = 3(6x – 4), find BD.
A1

C6
D9
Answer: c6
Step-by-step explanation:
The measure of the diagonal BD is 15 units.
What is a square?A square is a quadrilateral with four equal sides. There are many objects around us that are in the shape of a square. Each square shape is identified by its equal sides and its interior angles that are equal to 90°.
Given that, the diagonals of square ABCD intersect at point E.
Here, BE = 2x + 1, and AC = 3(6x-4)
Now, AC=BD
BD=2BE
So, 3(6x-4)=2(2x+1)
18x-12=4x+2
18x-4x=2+12
14x=14
x=1
So, BD=3(6x-1)=15
Therefore, the measure of the diagonal BD is 15 units.

Miguel already knows that he will have $550,000 when he retires. If he sets up a payout annuity for 22 years in an account paying 4% interest, how much could the annuity provide each month? Round your answer to the nearest dollar.
Answer:
Monthly withdraw= $3,124.19
Step-by-step explanation:
Giving the following information:
Present Value (PV)= $550,000
Number of periods (n)= 22*12= 264 months
Interest rate (i)= 0.04/12= 0.0033
To calculate the monthly withdrawal, we need to use the following formula:
Monthly withdraw= (PV*i) / [1 - (1+i)^(-n)]
Monthly withdraw= (550,000*0.0033) / [1 - (1.0033^-264)]
Monthly withdraw= $3,124.19

Answer:
52.48x ≤ 288.64
x≤5.5, x=5
Step-by-step explanation:
First off, we must find out how much money he has available after buying the bike, reflectors and gloves:
Total spent = (price of bike)+3(price of reflectors)+(price of gloves)
=233.09+3(16.38)+29.13
=311.36
600-311.36=288.64, so he has $288.64 left to spend on outfits.
The cost of x amount of outfits is found by multiplying the amount of outfits, x, by the cost per outfit, 52.48: 52.48x. Since he can only spend up to $288.64, 52.48x must be less than or equal 288.64:
52.48x ≤ 288.64
To solve, divide both sides by 52.48:
x≤5.5
(Since he cant buy half of a product, x's maximum value is 5)
