C. 5 and up
D. $30
Step-by-step explanation:
2. The truth will prevail. (Justify your answers, no justification, no credit). (12 points each) a) In any given sample, the median is never larger than the mean, unless the distribution is symmetric. True or False. b) The sign of the correlation coefficient provides us with information regarding how good a line fits the data points we are studying. True or False. c) The range is always larger than the inter-quartile range. True or False
Answer:
False ;
False ;
False
Step-by-step explanation:
In a perfectly symmetric distribution, the mean and Median values are the same. But for skewed distributon, the median is greater than the mean (negatively skewed or left skewed data). Hence, the assertion is false.
The sign of the correlation Coefficient does not give information about how good a line fits. The sign attached to the correlation Coefficient gives information about the slope and hence, the type of relationship between the variables.
Positive (+) sign = positive relationship between variables ; negative (-) sign = negative relationship between variables.
C.)
The value of the range is not always higher Than the value of the interquartile range. The IQR might have the same value as the value of the range.
For instance :
Given the data :
1, 1, 1, 2, 2, 3, 4, 4, 4
Range = maximum - minimum
Range = 4 - 1 = 3
Interquartile range (IQR) :
IQR = Q3 - Q1
Q3 = 3/4(n+1)th term
Q3 = 3/4(10) = 7.5th term
Q3 = (7th + 8th) / 2 = (4+4)/2 = 4
Q1 = 1/4(10) = 2.5th term
Q1 = (2nd + 3rd) / 2
Q1 = (1 + 1) /2 = 1
Q3 - Q1 = 4 - 1 = 3

Answer:
3/18 foot³
Step-by-step explanation:
okay, so the formula for volume is height x base, which is real confusing, but lets go:
first, you have to figure out the base, which is the surface that's on the bottom:
1/2 x 1/2 = 1/4
so you then multiply that by how high the figure is:
1/4 x 3/4 = 3/16
So your answer is option D. 3/18 cubic foot
hope this helps:)

You sell 500 shares of Coldwater Creek stock (CWTR). You purchased the stock at $2.98 per share and sold it at $0.88
per share. What was the percent decrease in the stock? Round to the nearest whole percent.
Answer:
70%
Step-by-step explanation:
Given that,
Cost price of the stock = $2.98 per share
Sold price of the stock = $0.88 per share
We need to find the percent decrease in the stock. It can be done as follows :
[tex]\%=\dfrac{2.98-0.88}{2.98}\times 100\\\\=70.46\%[/tex]
or
= 70%
So, the decrease in the stock is equal to 70 %.
Hey, may I get some help, thank you so much.
Answer:
C) sinF=27/45
Step-by-step explanation:
Because both triangles are similar, that means their sides are proportional to each other. Since sin∅=opposite/hypotenuse, then if sinC=3/5, we must find a ratio that is proportional to 3/5. Option C seems to work because 27/45=3/5, so sinF=27/45
Which polynomial has the highest degree?
A 3x^12 - 2x^8 + x^5
B 8x - 200
C 15x^3 + 3x^2 - 10
D 150x^3
Answer:
A 3x^12 - 2x^8 + x^5
Step-by-step explanation:
Degree of a polynomial:
The degree of a polynomial is given by the highest exponent of x.
In this question:
Option A: 12th degree
Option B: 1st degree

Four more than 5 times the number x is less than 50. Write an inequality for this statement.
Answer:
5x<50
Step-by-step explanation:
Answer:
Step-by-step explanation:
5n < 50 <--- subtracts 4 from both sides
n < 10 <--- divides both sides by 5
Check: testing n=0, we have 4 + 5(0) = 4 + 0 = 4 < 54, so yes it works
testing n=10, 4 + 5(10) = 4 + 50 = 54.
testing n=11, 4 + 5(11) = 4 + 55 = 59 <--- fails as expected.
X < 10, proven, verified, correct

The Colvilles are buying a new car. The cash price is $35,000.00. They will make a down payment of 20% or $5,000. The balance will be covered by an installment loan. The loan will be repaid in 48 monthly payments of $651. The annual percentage rate for the loan is
%. (Round your answers to two decimal places.)
9514 1404 393
Answer:
2.01% for a down payment of $5000
5.49% for a down payment of 20%
Step-by-step explanation:
There is no formula for the APR of a loan, given its other parameters. The value must be found using iterative or graphical means. The attached shows a graphical solution for each of the two cases for a 4-year loan.
For 20% down payment, APR ≈ 5.49%
For $5,000 down payment, APR ≈ 2.01%
Answer:
2.01% for a down payment of $5000
5.49% for a down payment of 20%

help me pleaseee. I don’t understand why this wrong so it would be great if you could help?
Answer:
-4x + 5y = 40
Step-by-step explanation:
- move the expression to the left, so you want to get y - 4/5x = 8
- multiply both sides so you get 5y - 4x = 40
- reorder the terms so you get -4x + 5y = 40
personally, I would change the signs afterwards to get 4x - 5y = -40, but the last thing I wrote was what was shown in that picture you sent. hope this helped :)

Car initial price= 12000
Depreciation= 10% or 0.10 per year
Car final price= Initial price-(Initial price/depreciation)
Car final price= 12'000-(1'200)
Car final price= 10'800
How do I work out 60% of 25?
Answer:
15
Step-by-step explanation:
Multiply: 25x.60=15
The reason why you multiply 25 times .60 is because you need to change the percentage to a decimal. The way you change you from a percentage to a decimal is by moving the decimal twice to the left.
So, 60%=.60
