Answer:
11/6
Step-by-step explanation:
To isolate the y on one side of the equation, you must first subtract 11x from both sides. Then the equation becomes -6y = -11x - 36.
Then you must divide both sides by -6 to isolate the y. The coefficient of the variable x becomes -11/-6, which is just 11/6.
Consider a sample with data values of 27, 24, 19, 14, 30, 35, 28, and 24. Compute the 20th, 25th, 65th, and 75th percentiles.
Answer:
20th percentile = 19
25th percentile = 21.5
65th percentile = 28
75th percentile = 30
Step by Step Explanation:
Computation for the 20th, 25th, 65th, and 75th percentiles
First step is to arrange sample with data values of 27, 24, 19, 14, 30, 35, 28, and 24 in Ascending order
Ascending order of given data
14,19,24,24,27,28,30,35
Now let Compute for the 20th, 25th, 65th, and 75th percentiles
Using this formula
I=P/100*n
Where,
n =8 given data values
Let plug in the formula
1. 20th PERCENTILE
20th PERCENTILE = (20/100) * 8
20th PERCENTILE= 1.6
20th PERCENTILE = 2 (rounded up to the nearest integer)
The 20th percentile is the 2th value in the given date that was arranged in ascending order which is 19
Therefore the 20th percentile is 19.
2. 25th PERCENTILE
25th PERCENTILE = (25/100) * 8
25th PERCENTILE= 2
To get the 25th percentile of 2 we would take the average of 2nd and 3rd value
25th PERCENTILE = (19 + 24)/2
25th PERCENTILE=43/2
25th PERCENTILE= 21.5
Therefore the 25th percentile is 21.5
3. 65th PERCENTILE
65th PERCENTILE = (65/100) * 8
65th PERCENTILE= 5.2
65th PERCENTILE= 6 (rounded up to the nearest integer)
The 65th PERCENTILE is the 6th value which is 28
Therefore 65th percentile is 28
4. 75th PERCENTILE
75th PERCENTILE = (75/100) * 8
75th PERCENTILE = 6
To get the 75th PERCENTILE of 6 we would take the average of 6th and 7th value
75th PERCENTILE = (28+30) / 2
75th PERCENTILE =58/2
75th PERCENTILE = 29
Therefore the 75th percentile is 30
Therefore the 20th, 25th, 65th, and 75th percentiles are:
20th percentile = 19
25th percentile = 21.5
65th percentile = 28
75th percentile = 30

What is measure p angles has 5 sides
Answer:
[tex]\huge\boxed{m\angle P = 94\textdegree}[/tex]
Step-by-step explanation:
In order to answer this question, we need to note a couple of things about the angle relationships in a pentagon.
A) The sum of the measures in a pentagon will be 540° (We know this because the angle sum formula tells us that an n sided polygon angles will have a sum of [tex](n-2) \cdot 180[/tex] - 180 * 3 = 540).B) Equations can represent angle measures, added together will help us determine their value.Since we know the sum of all of the angles will be 540, we can create an addition statement to find out the value of x.
[tex]132 + (4x-10) + (5x-11) + 128 + (4x+2)=540[/tex]
Let's solve for x.
Combine the angles we already know:[tex]132 + 128 =260[/tex] Combine like terms: [tex]260 + 13x - 19=540[/tex] Add 19 to both sides, subtract 260 from both sides: [tex]13x =299[/tex] Divide both sides by 13: [tex]x = 23[/tex]Now that we know the value of x, we can substitute it into the expression for point P ([tex]4x+2[/tex]) to find it's value.
[tex]4 \cdot 23 + 2[/tex] [tex]92+ 2[/tex] [tex]94[/tex]Therefore, the angle of measure P is 94°.

one of the roots of the equation 27x^2 + bx + 8 =0 is known to be the square of the other. Find b
Answer: Your going to have to correct your placing of your numbers.
-12 is value of b for equation 27x²+bx+8=0
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
Given,
One of the roots of the equation 27x² + bx + 8 =0 is known to be the square of the other.
We need to find the value of b.
Let one root is a and the other root is a².
(x-a)(x-a²)=0
x²-xa²-ax+a³=0
x²-x(a²+a)+a³=0
Now multiply by 2
x²-2x(a²+a)+2a³=0
x² + bx + 16=0
2a³=16
Divide both sides by 2
a³=8
a=2
27x²-2x(a²+a)+2a³=0
27x²-2x(4+2)+16=0
27x²-2x(6)+16=0
27x²-12x+16=0
b=-12
Hence, -12 is value of b for equation 27x²+bx+8=0

If 2x +9= 23, then 3x =
Answer:
21
Step-by-step explanation:
First you have to solve for x in the equation 2x + 9 = 23. Cancel 9 on both sides. You cancel 9 by subtracting 9 on the left side and on the right side:
23 - 9 = 14.
Now, you have 2x = 14. To isolate the variable, divide by 2 to cancel out 2.
14 / 2 = 7.
This will give you x = 7. Now that you know what x equals, you can substitute x in 3x. This would make it 3(7), or in other words 3 x 7.
3 x 7 = 21.
This means that 3x would be equal to 21. Hope it helps!
Answer:
to solve typical question like this first u have to find (x)[tex]2x + 9 = 23 \\ x = \frac{23 - 9}{2 } \\ x = \frac{14}{2} = 7[/tex]

You decide to record the hair colors of people leaving a lecture at your school. What is the probability that the next person who leaves the lecture will have blonde hair ?
Express your answer as a simplified fraction or a decimal rounded to four decimal places.
Blonde Red Brown Black Gray
31 25 18 40 42
Answer: the probability that the next person who leaves the lecture will have blonde hair is 0.1987
Step-by-step explanation:
Given that;
HAIR COLOR FREQUENCY
Blonde 31
Red 25
Brown 18
Black 40
Gray 42
Total 156
So
there were 156 people all together
and out of the 156, 31 of them were blonde.
now the probability that the next person who leaves the lecture will have blonde hair will be;
⇒ 31 / 156 = 0.1987
Therefore, the probability that the next person who leaves the lecture will have blonde hair is 0.1987

A. 21
B. 77
C. 91
D. 115
E. 143
Hint : Use Wilson's Theorem[tex].[/tex]
Answer:
C. 91Step-by-step explanation:
Rewriting the given as factors:
12! · 6! + 12! + 6! + 1 =12!(6! + 1) + (6! + 1) =(12! + 1)(6! + 1) =((13 - 1)! + 1)((7 - 1)! + 1)As per Wilson's theorem, if n is prime number, (n - 1)! + 1 is divisible by n
As per above, 13 and 7 are both prime numbers, so the expression is divisible by both 7 and 13:
7*13 = 91So correct choice is C
