what is probability?
the probability is the department of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The chance of an event is a number between 0 and 1, in which, roughly speaking, zero indicates the impossibility of the event and 1 shows certainty.
probability = the number of ways of attaining success. the total number of possible results. For instance, the chance of flipping a coin and its being heads is ½, due to the fact there may be 1 way of getting a head and the total number of possible outcomes is two (a head or tail).

a. -2.2
C. 16
b. 100
d. 2.2
Answers
Mean is 84
Cindy got a 100
(100-84)/7.35=2.2
D FINAL ANSWER
Based on the test scores of the students, Cindy's z-score on the science test is 2.2
How to determine the z-score of Cindy?We start by calculating the mean of the scores using:
Mean =Sum/Count
So, we have:
Mean = (75 + 80 + 90 + 100 + 75 + 85 + 80 + 80 + 90 + 85)/10
Mean = 84
Using a statistical calculator, the standard deviation is:
Standard deviation = 7.35
The z-score is then calculated using:
z = (x - mean)/standard deviation
Cindy's score is 100.
So, we have:
z = (100 - 84)/7.35
Evaluate
z = 2.2
Hence, Cindy's z-score on the science test is 2.2

Draw a line across the east and west farthest points. If you count the lower left point as 0,0, I am talking about 1,6 and 7,6 What that does is divide the figure into a triangle and a trapezoid.
Triangle
The base goes from x = 1 to x = 7 when that new line is introduced which is 6 units parallel to the x axis.
The height goes from 4,4 to 4,6 which is 2 units in the y direction.
So the area = 1/2 (2)*(6) = 6 units.
Trapezoid.
h = 3 derived from 4,3 to 4,6 which is 3 points 6 - 3 = 3
b1 = 6 That's the line you just drew in.
b2 = 4 That comes from 2,3 to 6,3 6-2 = 4
Area = 1/2 (b1 + b2) * h
Area = 1/2 (6 + 4)* 3
Area = 5 * 3 = 15
Total Area = 15 + 6 = 21

Parallelogram Q T S R is shown. Sides Q T and R S are parallel, and sides Q R and T S are parallel. Angle Q is (9 x minus 6) degrees and angle R is (8 x minus 1) degrees. Devin started the work shown to solve for the unknown angle measures. 8x – 1 + 9x – 6 = 180 17x – 7 = 180 17x = 187 What are the measures of angles Q and R? m∠Q = ° m∠R = °
Answers
Answer:
m<Q = 93 degrees
m<R = 87 degrees
Step-by-step explanation:
Given the following angles;
m<Q = 9x-6
m<R = 8x-1
Looking at Devin's work, we will see that he the sum of both angles is 180 degrees
Hence m<Q + m<R = 180
9x - 6 + 8x - 1 = 180
9x+8x-6-1 = 180
17x - 7 = 180
17x = 180 + 7
17x = 187
x = 187/17
x = 11
Get m<Q
m<Q = 9x - 6
m<Q = 9(11) - 6
m<Q = 99 - 6
m<Q = 93 degrees
Get m<R
m<R = 180 - m<Q
m<R = 180 - 93
m<R = 87degrees

Answer:
4(7x-2)
Step-by-step explanation:
yeah so that's the answer your welcome
The factor of the polynomial expression 28x - 8 will be 4 and (7x - 2).
What is factorization?It is a technique for separating a polynomial into sorts that will be duplicated out. As of now, the polynomial's worth will be zero.
Polynomial math is the investigation of conceptual images, while rationale is the control of that multitude of thoughts.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The expression is given below.
⇒ 28x - 8
Factorize the expression, then we have
⇒ 28x - 8
⇒ 4·7x - 4·2
⇒ 4(7x - 2)
The element of the polynomial articulation 28x - 8 will be 4 and (7x - 2).

Michael has $68. Craig has $24 less than Michael has. Michael spends $20 on a new hat. Part A: Write an equation where the solution represents the amount of money (x), in dollars, Craig has after Michael buys the hat. Explain how you came to this equation. Part B: Now, Craig buys some socks. He has $16 left. Write an equation where the solution represents the amount of money (y), in dollars Craig spent on socks. Show how you know this is the correct equation.
Answers
Answer:
a) x + 4 = 48
b) y + 16 = 44
Step-by-step explanation:
a) Michael has $28 and Craig has $24 less than Michael. Let x represent the amount of money that Craig has. Hence:
x = 68 - 24
x + 24 = 68
Given that Michael spends $20 on a new hat. Therefore we subtract 30 from both sides of the equation:
x + 24 - 20 = 68 - 20
x + 4 = 48
x = $44
b) If y represent the amount of money that Craig spent on buying socks. He has 16 remaining.
Therefore:
44 - y = 16
y + 16 = 44
y = $28
Eight friends share 2 pumpkin pies equally. What fraction of a pumpkin pie does each friend get?
Answers
Answer:
1/4
Step-by-step explanation:
If there are two pies and eight friends, then 4 friends split each pie. I know this because if you divide eight by two (because there are 8 friends and 2 pies) then you get 4, which means then 4 friends split each pie. You would then figure out how many slices you need to split each pie into. Since there are 4 people per pie, you would split each pie into 4 sections. Each friend would get 1/4 of a pie.
I hope this makes sense to you. If you need any more help, please let me know. I'm always happy to help! :]

What is the length of side d?
A. 5 centimeters
B. 8 centimeters
C. 12 centimeters
D. 25 centimeters
Answers
Explanation:
Use formula a^2 + b^2 = c^2 but in this case letter “d” will substitute for “b”
Since 13 is hypotenuse, 13 is going to be the letter c
12 is “a” because we don’t know “d”
So it’s 12^2 + d^2 = 13^2
Simplify: 144 + d^2 = 169
Subtract to isolate d^2: d^2 = 25
Take square root from both sides to isolate d: d = 5

A bookmark has an area of 14 square centimeters and a perimeter of 18 centimeters. What are the dimensions of the bookmark?
Answers
Answer:
2 x 7
Step-by-step explanation:
a * b = 14
2a + 2b = 18
(a * b)/b = 14/b Dividing both sides by b
a = 14/b
Substitute a in the perimeter equation
2(14/b) + 2b = 18
28/b + 2b = 18
2b - 18 + 28/b = 0
Multiply both sides by b
2b^2 - 18b + 28 = 0
Divide both sides by two
b^2 - 9b + 14 = 0
The Factors of 14 include -2 and -7 which add up to -9
(b - 2) * (b - 7) = 0
This has two answers because b can be either the side that is 2 long or 7 long, so there's no need to go back and solve for a.
