Answer:
A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.

a.18 b.6 c.3 d.-6
16=4x+8
a.1/2 b.4 c.2 d.6
4z+8=40
a.10 b.4 c.8 d.28
5x-7=38
a.5 b.6 c.14 d.9
-3x-9=24
a.11 b.-11 c.5 d.-5
Answer: 1 is b
2 is c
3 is c
4 is d
5 is b
Answer:
12=3x-6 is 6
16=4x+8 is 2
4z+8=40 is 8
5x-7=38 is 9
-3x-9=24 is -11
Step-by-step explanation:
for 12=3x-6 you would get x by itself so first you add the 6 to the 12
you get 18 then you try to get the x by itself so you divide 3x by 3 and divide 18 by 3 as well. So you end up with 6=x. Repeat with every problem
How do I simplify radicals?
Answer:
Step 1: Find the prime factorization of the number inside the radical. Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder. Then divide by 3, 5, 7, etc. until the only numbers left are prime numbers. Click on the link to see some examples of Prime Factorization. Also factor any variables inside the radical.
Step 2: Determine the index of the radical. The index tells you how many of a kind you need to put together to be able to move that number or variable from inside the radical to outside the radical. For example, if the index is 2 (a square root), then you need two of a kind to move from inside the radical to outside the radical. If the index is 3 (a cube root), then you need three of a kind to move from inside the radical to outside the radical.
Step 3: Move each group of numbers or variables from inside the radical to outside the radical. If there are nor enough numbers or variables to make a group of two, three, or whatever is needed, then leave those numbers or variables inside the radical. Notice that each group of numbers or variables gets written once when they move outside the radical because they are now one group.
Step 4: Simplify the expressions both inside and outside the radical by multiplying. Multiply all numbers and variables inside the radical together. Multiply all numbers and variables outside the radical together.
Example:
Example 1 – Simplify: Example 1
Step 1: Find the prime factorization of the number inside the radical.
252=2*2*3*3*7
Step 2: Determine the index of the radical. In this case, the index is two because it is a square root, which means we need two of a kind.
√252= √2*2*3*3*7
Step 3: Move each group of numbers or variables from inside the radical to outside the radical. In this case, the pair of 2’s and 3’s moved outside the radical.
2*3√7
Step 4: Simplify the expressions both inside and outside the radical by multiplying.

Sergei uses 4 cups of ice cream to make 3 milk shakes.
How many cups of ice cream does he need to make 5 milk shakes?
A. cups of ice cream
B. 4 cups of ice cream
C. 5 cups of ice cream
D. cups of ice cream
Answer:
i would say 5 cups, let me know if i'm wrong
Sergei need 7 cups of ice cream to make 5 milk shakes.
What is Proportional?Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
Sergei uses 4 cups of ice cream to make 3 milk shakes.
Let number of cups of ice cream does he need to make 5 milk shakes = x
So, By definition of proportion, we can formulate;
⇒ Number of cups of ice-cream / Milk shakes
⇒ 4 / 3 = x / 5
⇒ 4 × 5 / 3 = x
⇒ x = 20/3
⇒ x = 6.67
⇒ x ≈ 7

Using the drawing tool, graph the two inequalities on the number line. Take a screenshot of each number line and submit it in the response area below. For this scenario, how does the origin, zero, affect the graphing of the inequalities? What does zero represent? Type your answers in the response area.
The attached number lines represent the inequalities x ≥ 22 and x > -22
The inequalitiesTo answer these questions, we make use of the following inequalities
x ≥ 22 and x > -22
The ≥ inequality sign uses a closed circle, while the > inequality sign uses an open circle.
See attachment for the number line
The impact of the originThe origin of a number line is the point zero on the number line.
It affects the graphing of the inequality because it differentiates between the positive sign and the negative sign.
Also, it is always the midpoint of the number line

The slope of LN¯¯¯¯¯ is equal to the slope of NP¯¯¯¯¯¯. This because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is the same for LN¯¯¯¯¯ as for NP¯¯¯¯¯¯
The relationship between the slope of LN¯¯¯¯¯ and the slope of NP¯¯¯¯¯¯ cannot be determined, because the triangles are congruent.
The slope of LN¯¯¯¯¯ is greater than the slope of NP¯¯¯¯¯¯. This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is greater for LN¯¯¯¯¯ than for NP¯¯¯¯¯¯.

Answer:
6 pencils
Step-by-step explanation:
i looked it up
Answer:
6 Mechanical Pencils
Step-by-step explanation:
So Katie NEEDS 3 binders so that is given. 3.25 times 3 is 9.75 so subtract that from 20 which is 10.25. Divide 10.25 by 1.5 and get 6.8. You cant buy .8 of a pencil so you go down to 6.

Slope Intercept Form given slope and y-intercept
Formula= Y=Mx+B
Mx= 2
B= -4
Explain the answer and what is the slope intercept form
Answer:
the slope intercept form for this equation is y=2x-4 where mx represents the slope and b represents the y intercept.
Step-by-step explanation:
slope intercept form is a form of an equation of a line written as y= mx + b where m is the slope and b is the y intercept.
in this case we are given the slope and y intercept, so all we need to do is plug it into the original equation in the correct spots.
after we have done this we will get y=2x+-4
once we simply we will get y=2x-4
An amusement park’s goal is to sell 1 million tickets within the first four months of its being open.
How many more tickets does the park need to sell in Month 4 to reach this goal?
About how many tickets will the park need to sell in Month 4?
≈______ tickets.
Answer:
look at the explenation
Step-by-step explanation:
Hello! does it say how many have already been sold? if not then each month is 250,000 tickets
The amusement park needs to sell 250,000 more tickets in Month 4 to reach its goal of 1 million tickets in four months.
We can calculate the average number of tickets the amusement park needs to sell each month in order to determine how many more tickets they need to sell in Month 4 in order to meet their target of selling 1 million tickets within the first four months.
1,000,000 tickets ÷ 4 months = 250,000 tickets per month
250,000 tickets per month × 3 months = 750,000 tickets sold in the first three months
1,000,000 tickets goal - 750,000 tickets sold = 250,000 more tickets needed in Month 4
To reach its objective of selling 1 million tickets within the first four months, the theme park needs to sell 250,000 more tickets in Month 4.
average monthly target ≈ 250,000 tickets.
