Answer:
Yes, it could be a probability
Step-by-step explanation:
The probability of an event HAS to be between the numbers 0 and 1. Not less than 0, not greater than 1. The number 0.12 is between 0 and 1, thus, making it a valid probability.

Answer:
-16
-10
-4
2
Step-by-step explanation:
y = 3x - 4
x = -4, y = 3(-4) - 4 = -16
x = -2, y = 3(-2) - 4 = -10
x = 0, y = 0 - 4 = -4
x = 2, y = 3(2) - 4 = 2

Two different companies sell canned peaches at the following rates:
Company a: 8onces for $2.50
Company b: 6 ounces for $2.10
Which company offer the lower cost per once?
At a pizza place, a large pizza cost $7.50 and toppings cost $0.50 each. Write an equation the can be used to represent the cost of a pizza, y, which x toppings.
Answer:
y = 7.50 + 0.50x
Step-by-step explanation:
y is equal to money cost for pizza, 7.50 is the large pizza, and 0.50x is the cost per topping on the pizza.

The image represents a rectangular patio that has a length equal to 4 feet more than the width. What is the perimeter of the patio?
Answer:
4w+8 feet
Step-by-step explanation:
The perimeter of a rectangle is the sum of the lengths of its sides. Since opposite sides are identical in length, it can be computed as double the sum of adjacent side lengths. Here, the lengths are in feet.
P = 2(L+W)
P = 2((w+4) +w)
P = 4w +8
The perimeter of the patio is 4w+8 feet.
AB and BC form a right angle at point B. If A= (-3, -1) and B= (4, 4), what is the equation of BC
A. x + 3y = 16
B. 2x + y = 12
C. -7x - 5y = -48
D. 7x - 5y = 48
Answer:
(C) -7x - 5y = -48
Step by step explanation:
We look for the equation of the line AB
We have then:
y-yo = m (x-x0)
m = (y2-y1) / (x2-x1)
m = (4 - (- 1)) / (4 - (- 3))
m = 5/7
We choose an ordered pair:
(xo, yo) = (4, 4)
Substituting:
y-4 = (5/7) (x-4)
y = (5/7) x-20/7 + 4
7y = 5x - 20 + 28
7y = 5x + 8
y = (5/7) x + 8/7
The equation of the perpendicular line is:
-7x - 5y = -48

If two opposite sides of a square are increased by 15 meters and the other sides are decreased by 13 meters, the area of the rectangle that is formed is 60 square meters. find the area of the original square.
Answer: Shown below
Step-by-step explanation:
Since it's a square, we will refer to its values as x. Using that, we can make an equation for the rectangle.
(x + 15) * ( x - 13) = 60
We can expand it and simplify so that we get a zero on one side and a polynomial on the other.
(x + 15)(x - 13) - 60 = 0
x² + 2x - 225 = 0
We simplify the binomial so we get two answers for x.
(x - 15)(x + 17) = 0
x = 15 and -17
Now we have two answers. So which one is right? Well, the sides cannot be negative, therefore we must use 15 and not -17.
15² = 225
Our answer is 225
The world population is projected to be 8.2 billion in 2045. At that time, there are expected to be approximately 3 billion more people in Asia than in Africa. The population for the rest of the world will be approximately 0.2 billion more than half the population of Asia. Find the projected populations of Asia, Africa, and the rest of the world in 2045.
The projected population of Asia will be approximately billion
Answer:
Since the total population will be 9.4B people
W + A+ A =9.4B
W = 0.6B + A/4
A+ 2.9B = As
A - 2.9B + As + 0.6 + A/4 = 9.4B
(9/4)*A= 11.7B
A = (4/9)*11.7B=5.2B
W = 0.6B + (5.2B/4) = 1.9B
A = 5.2B - 2.9B = 2.3B

Answer:
1 and 7/8 is the change.
Step-by-step explanation:
First, make the bottom to fractions have the same denominator so we can figure out the length of the other route. 2 and 3/8 will become 2 and 9/24.
Then 3 and 5/6 will become 3 and 20/24. Add them both to get 6 and 5/24. since we cant simplify it stays the same. so now we convert the other number for the new road so it can match the old route. 4 and 1/3 become 4 and 8/24. Now we finish off by subtracting our two numbers to get 1 and 21/24. Since we can simplify the number now becomes 1 and 7/8.
Hope this helped.

Jayden's monthly bank statement showed the following deposits and withdrawals:
-−$73.59, -−$7.81, $86.90, $6.74, -−$115.75
If Jayden's balance in the account was $85.62 at the beginning of the month, what was the account balance at the end of the month?
Answer:
-17.89
Step-by-step explanation:
I think this is the answer
Start with the beginning balance then add or subtract the given amounts:
85.62 -73.59 = 12.03
12.03-7.81 = 4.22
4.22 + 86.90 = 91.12
91.12+ 6.74 = 97.86
97.86-115.75 = -17.89
Answer: -$17.89

Find f(h(-1)).
-9
2
11
-11
Answer:
f(h(-1)) = - 11 or D
Step-by-step explanation:
h(-1) = -2(-1)^2 - 3(-1) + 1
h(-1) = -2(1) + 3 + 1
h(-1) = 2
f(2) = (2t + 7)/(t - 3)
f(2) = (2*2 + 7) / (2 - 3)
f(2) = 11/-1
f(2) = - 11
Be very careful how you handle this. The way I have done it will work, but it does not work all the time.
The sure way to handle this is to put(h(n)) every place you can on the right side of f(t)
f(h(n)) = (2(h(n) + 7)) / (h(n) - 3)
Can a parallelogram have more than 3 lines of symmetry?
Answer:
no
Step-by-step explanation:
Parallelograms have zero lines of symmetry because it is impossible to draw a line through the center of any parallelogram that divides the figure into two equal halves that are mirror images of each other.
Answer:
Technical answer no
BUT
if you are in a college/postgraduate level group theory class yes
Step-by-step explanation:
Imagine a square, and imagine 4 lines across the top, the side, and the two diagonal ones. Because the two diagonal lines of symmetry are technically the same, there are only three possible lines.
if you are in the group theory class, comment and ill give a lengthy answer on that.
A side of the triangle below has been extended to form an exterior angle of 135°. Find the value of x.
