Your grades on 4 math tests are 79, 85,
86, and 88. You want your mean grade to
be at least 85. What grade on your fifth
test will give you a mean score of at least
85?
Answer:
The grade on the fifth test that will give you a mean score of at least 85 is 87
Step-by-step explanation:
From the question, the grades on 4 math tests are 79,85,86, and 88.
To determine the grade on the fifth test that will give a mean score of at least 85,
Let the grade on the fifth test be x,
From the formula for mean
Mean = Sum of terms / Number of terms
That is,
85 = (79 + 85 + 86 + 88 + x) / 5
[tex]85 = \frac{79 + 85 + 86 + 88 + x}{5}[/tex]
[tex]85 = \frac{338 + x}{5}[/tex]
[tex]338 + x = 85 \times 5[/tex]
[tex]338 + x = 425\\[/tex]
[tex]x = 425 - 338[/tex]
[tex]x = 87[/tex]
x = 87
Hence, the grade on the fifth test that will give you a mean score of at least 85 is 87.

The Powerball lottery jackpot has a winning probability of 1/189,000,000. If you only consider the options of winning the jackpot ($100,000,000) or losing, what the is the mean value of a ticket that costs $2 to buy? At what point does the mean value of a ticket become positive?
Answer:
In this case, we can write the mean value as:
MV = ∑pₙxₙ - $2
Where pₙ is the probability of event xₙ
in this case we consider only two events:
x₁ = winning $100,000,000, p₁ = 1/189,000,000
x₂ = not winning (or winning $0.0), p₂ = 1 - p₁.
Then the mean value of the ticket is:
MV = $100,000,000*1/189,000,000 + 0*(1 - 1/189,000,000) - $2 = $0.53 - $2
MV = -$1.47
b) At what point the mean value becomes positive?
Well, if the ticket costs less than $0.53, the value would become positive.
if we also consider other possible prices, we will have other positive components in the sum above, then the mean value may become positive.
Now, you may notices that it does not matter if you buy N tickets, the mean value will always be negative becuase:
MV = N*$0.56 - N*$2 = N*-$1.47
This is because yes, as more tickets you buy, the more probabilities of winning the prize you have, but if you buy N tickets, you need to pay N times $2, so the mean value actually decreases.

Answer:
The average of the grade is 7.
Step-by-step explanation:
Add all of the grades up then divide by the number of grades there are
8+8+5=21
21÷3=7
Have a blessed day! I hope my answer was helpful!!
Answer:
The answer is 7
Step-by-step explanation:
So, we need to distribute the mean, (AKA:) average.
There is a rule when finding the average of numbers.
That rule is:
Adding all of the numbers together and dividing that sum by how many numbers there are in total that you added together.
1. First, we to add 8 and 8.
2. 8 + 8 = 16
3. Next, we need add to 5 to that 16.
4. 5 + 16 = 21
5. Since we have 3 numbers, we need to divide that 21 by 3.
6. 21 / 3 = 7
Thus showing that our answer is 7.
When trying to find the mean of numbers, always remember the rule of finding the average.

the model shows the expression 21+9 wich expression is equivalent to this sum
Answer:
A
Step-by-step explanation:
First way to do this:
3(7 + 3)
7 + 3 = 10
10 multiplied by 3 = 30
Second way to do this:
3(7 + 3)
3 multiplied by 7 = 21
3 multiplied by 3 = 9
21 + 9 = 30

What is the slope of the line that passes through the points(2,−3) and (2, 13) ?
Answer:
The slope would be undefined (16/0)
Step-by-step explanation:
(2, -3) and (2, 13)
13- -3 = 16
2-2 = 0
16 divided by 0 is undefined on a calculator so, undefined is the answer unless you weren't asked to simplify the answer then it would be 16/0.
Please help
Find the slope between (2,4) and (5,8).
Answer:
Not sure what you exactly need, so I'll give a simple answer=4/3 or 1 1/3
Step-by-step explanation:
Slope is the change in y over the change in x. Substitute the numerator and denominator and you'll get the slope. Substitute the numerator for 4 and the denominator for 3. You get 4/3, or 1 1/3.

A brother and sister share out their collection of 5000 stamps in the
ratio 5:3. The brother then shares his stamps with two friends in
the ratio 3:1:1, keeping most for himself. How many stamps do
each of his friends receive?
13
Answer:
1875
Step-by-step explanation:
After sharing in the ratio 5:3, the brother has
5000/(5+3) x 5 = 3125
Next, he shares with his friend in the ratio 3:1:1, thus
3125/(3+1+1) x 3 = 1875

Chloe's car used 4 gallons to travel 72 miles. How many gallons of gas would she need to travel 270 miles?
Answer:
15 gallon of gas
Step-by-step explanation:
It is given that,
Chloe's car used 4 gallons to travel 72 miles.
We need to find number of allons of gas that would she need to travel 270 miles.
We firstly find gas required to travel 1 mile.
[tex]1\ \text{mile}=\dfrac{4}{72}\ \text{gallon}[/tex]
For 270 miles,
[tex]270\ \text{mile}=\dfrac{4}{72}\times 270\ \text{gallon}\\\\=15\ \text{gallon of gas}[/tex]
Hence, 15 gallon of gas is needed.

Mrs. Totino makes her own spaghetti sauce. If she buys 24 cans of tomatoes, and
each can weighs 79.254 grams, what is the total weight of the cans?
Well, this is easy and rather basic in my opinion. If you open a calculator and multiply 79.924 by 24, you come out with 1,902.96 grams. If you wanted to convert it into pounds, it would be 4 pounds.
