Answer:
15%
Step-by-step explanation:
17/20 the 17 is the part, and the 20 is the whole
17/20 = x/100
cross multiply
17*100= 1,700 divide by 20
=85
The price reduced to 85% the original price, but to find out how much it changed, you have to subtract the part from the whole meaning
100% - 85% = 15%

Its C I think
Step-by-step explanation:
turn the line that shows twelve and make it match the line that shows X and then the first line will be shorter
The value of x is 15.
What is Right triangle?
A triangle in which one of the interior angle is 90° is called a right triangle.
Given that;
Sides of a right triangle are 12, 9 and x.
Now,
By the Pythagoras theorem;
x² = 12² + 9²
x² = 144 + 81
x² = 225
x = √225
x = 15
Thus, The value of x is 15.

Answer:
4y^3 + 4x^2 - 2
Step-by-step explanation:
Sort out these terms following powers of x and y:
First, y terms:
6y^3 - 2y^3 => 4y^3
Next, constants:
7 - 7 - 2 => -2
Next, x^2 terms:
6x^2 - 2x^2 => 4x^2
Now write out the modified expression, using the "combined terms" results given above:

Luke has a board 5
6
of a yard long. He needs to cut the board into 5 equal sections.
Use the expression
to find the length of each section.
Each section is
yard long.
Answer:
1/6 of a yard
Step-by-step explanation:
Length of the board = 5/6 yard
He needs to cut the board into 5 equal sections.
Length of each section = length of the board ÷ number of sections
= 5/6 ÷ 5
= 5/6 × 1/5
= (5*1)/(6*5)
= 5/30
= 1/6
Length of each section = 1/6 of a yard

Roger is building a frame for a flower bed. He is using left-over scraps of wood from his garage. He needs a total of 12 feet of wood. The pieces he has in his garage are 314 feet, 412 feet, and 4 feet. Does he have enough wood to build the frame?
A. Yes, because 12 > 1134
B. Yes, because 1234 > 12
C. No, because 1134< 12
D. No, because 1116 < 12
Answer:
C. No, because 11.34 < 12
Step-by-step explanation:
3.14 + 4.12 + 4 has to be greater than or equal to 12
solve the equation
3.14 + 4.12 + 4 >= 12
7.26 + 4 >= 12
11.26 >= 12 is false
I don't know why it says 11.34 because the numbers don't add up, so I'll assume that there is a typo somewhere.

Step-by-step explanation:
To find the median, write down all numbers in numerical order and cross off one number from each side until you are left with the middle number.
One thing to keep in mind when doing this, though, is to make sure you cross off the same amount on each side, and if you have 2 numbers left, like 13 and 14, your answer would be the number exactly between those, 13.5.

HELP PLZ DUE RN BRAINIEST TO WHOEVER RIGHT
Answer:
x = 11, -1
Step-by-step explanation:
First, let's identify what the quadratic formula is:
x = [-b ± √(b² - 4(a)(c))] / 2
Our equation is written in standard form:
ax² + bx + c = 0
x² - 10x - 11 = 0
Let's plug in what we know.
x = [-(-10) ± √((-10)² - 4(1)(-11))] / 2
Evaluate the exponent.
x = [-(-10) ± √(100 - 4(1)(-11))] / 2
Simplify the negatives.
x = [10 ± √(100 - 4(1)(-11))] / 2
Multiply.
x = [10 ± √(100 + 44)] / 2
Simplify the parentheses.
x = [10 ± √(144)] / 2
Simplify the radical (√)
x = [10 ± 12] / 2
Evaluate the ±.
x = [10 + 12] / 2
x = [22] / 2
x = 11
or
x = [10 - 12] / 2
x = [-2] / 2
x = -1
Your answers are x = 11, -1

The probability of being a universal donor is 6% (O-negative-blood type). Suppose that 6 people come to a blood drive.' a) What are the mean and standard deviation of the number of universal donors among the 6 people? b) What is the probability that there are exactly three universal donors?
Answer:
[tex]Mean = 0.36[/tex]
[tex]SD = 0.5817[/tex]
[tex]P(x=3) = 0.003588[/tex]
Step-by-step explanation:
Given
Let
A = Event of being a universal donor.
So:
[tex]P(A) = 0.06[/tex]
[tex]n = 6[/tex]
Solving (a): Mean and Standard deviation.
The mean is:
[tex]Mean = np[/tex]
[tex]Mean = 6 * 0.06[/tex]
[tex]Mean = 0.36[/tex]
The standard deviation is:
[tex]SD = \sqrt{np(1-p)}[/tex]
[tex]SD = \sqrt{6*0.06*(1-0.06)}[/tex]
[tex]SD = \sqrt{0.3384}[/tex]
[tex]SD = 0.5817[/tex]
Solving (b): P(x = 3)
The event is a binomial event an dthe probability is calculated as:
[tex]P(x) = ^nC_x * p^x * (1-p)^{n-x}[/tex]
So, we have:
[tex]P(x=3) = ^6C_3 * 0.06^3 * (1-0.06)^{6-3}[/tex]
[tex]P(x=3) = ^6C_3 * 0.06^3 * (1-0.06)^3[/tex]
[tex]P(x=3) = 20 * 0.06^3 * (1-0.06)^3[/tex]
[tex]P(x=3) = 0.003588[/tex]
I play a gambling game in which I will win different amounts of money with different likelihood's. Suppose that I win X dollars with a probability of P(X) (if C is negative I am losing money). The distribution is as follows: what is the appropriate value of P?
Answer:
[tex]p = 0.05[/tex]
Step-by-step explanation:
Given
See attachment for the distribution
Required
Find p
To find p, we make use of:
[tex]\sum P(x) = 1[/tex]
So, we have:
[tex]0.50 + 0.25 + 0.13 + 0.07 + p = 1[/tex]
[tex]0.95 + p = 1[/tex]
Make p the subject
[tex]p = 1 - 0.95[/tex]
[tex]p = 0.05[/tex]
Mike took an uber from his home to the airport. The driver charges an initial fee of $6 and $3 per mile. The total fare was $24 not including the tip. How many miles did Mike travel by uber on this ride? *
Answer:
About 5 miles
Step-by-step explanation:
At first, I thought it would be 6 miles because 6x3 is 18 plus the initial 6 dollars which is 24. However, it says that it does not include the tip, which means that Mike DID tip the driver. So there has to be some space for the tip. If it was 6 miles it would be 24 dollars, but there is no more space for the tip. So it has to be 5 miles, because that will be 21 dollars, and assuming the tip could be about 3 dollars, then that would total up to 24 dollars.
