first prize and your mom win second prize?
a. 8

c. 10
d. 1
Answer:

What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
There are 10 people who entered the drawing.
Since the prizes are awarded at random, the probability of you winning the first prize is 1/3, and the probability of your mom winning the second prize is 1/2.
We can use the multiplication principle of counting to find the number of ways that you can win first prize and your mom can win the second prize.
The number of ways that you can win first prize is 1 since there is only one first prize and you are one of the 10 people who entered.
Once the first prize winner is chosen, there are 9 people left, and the number of ways that your mom can win the second prize is 1 out of 9.
The total number of ways that you can win first prize and your mom can win the second prize is:
1 × 1/3 × 1/2 × 9 = 3/2
However, the answer cannot be a fraction or decimal, since we are counting the number of ways in which events can occur.
Therefore, we round up to the nearest integer and get:
3/2 ≈ 2
Therefore,
There are 2 ways that you can win first prize and your mom can win the second prize.

1. Which is the slope of the line that passes through the points (1,1) and (2,7) ?
1a. Pick a point the line passes through above and with the slope you calculated, find the y- intercept
1b. Now that you know the y- intercept, what is the equation of the line ?
Hello!
1)First, they ask us to find the slope. [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1} }[/tex] is the slope formula.
The slope is 6
2)Let's just use the point they gave us (1,1)
We need to substitute the point in the equation and solve.
The y-intercept is -5
3) y=mx+b (m=slope b=y-intercept)
y=6x-5

Answer:
Perform the indicated multiplication: 2 - 3x - 12 = 9 - 3x
Gather all the x terms on one side and all the constants on the other:
-3x + 3x = 9 + 12 - 2, or 0 = 19
since this is never true, 2 - 3x - 12 = 9 - 3x has no solution.

A group of 8 friends went to lunh and Spent a total of $76 which included the food bill in the tip of $16 they decide to split the bill into evenly among themselves
Answer:
The equation 1/8(x+16)=76/8 represents the situation, where x is the food bill.
The solution x=60 represents the total food bill.
Step-by-step explanation:
As in the question it is mentioned that there is eight group of friends and the total amount incurred is $76 that also involved $16
Now let us assume the food bill be x
So the equation would be
(x + 16) ÷ 8 = 76 ÷ 8
(x + 16) ÷ 8 = 9.5
x + 16 = 9.5 × 8
x = 76 -16
x = 60
So, the bill of food is 60
