Step-by-step explanation:
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.

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.

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.

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.

rafael counted a total of 40 white and yellow cars. there are 9 times as many white cars as yellow cars. how many white cars did rafael count.
Answer:
360
Step-by-step explanation:
40 times 9 = 360
there are 360 yellow cars
or we can do it like this
360 divided by 9 = 40
or 360 divided by 40 = 9
pls mark me brailest for real :,,(
Answer:
360
Step-by-step explanation:
9 x 40 = 360
If you divide 360 by 9 it will give you 40,
or if you divide 360 by 40 it will give you 9.
The Palm Beach High Swimming Team is holding a car wash to raise money
for the team's banquet. All of the supplies for the car wash were donated by
parents of the team members. The graph below represents the situation.
SWIM TEAM CAR WASH
How much did the swim team charge for each car that it washed?
How much money did the swim team have in its account before the car wash?
If the team wants to earn $300, how many cars do they need to wash?
Answer:
Step-by-step explanation:
From the graph attached,
Relation between the amount of money raised and number of car washed is represented by a straight line.
Let the equation of the line is,
y = mx + b
where m = slope of the line = charges for each car wash
b = y-intercept = Initial amount the team have before the car wash.
Slope of the line will define the charges of car wash for each car.
Since, slope of the line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, slope of the line passing through (0, 100) and (10, 150) will be,
m = [tex]\frac{150-100}{10-0}[/tex]
m = 5
Therefore, charges of each car wash will be = $5
y-intercept of the line 'b' = 100
Equation of the line will be,
y = 5x + 100
If team wants to earn $300,
300 = 5x + 100
5x = 200
x = 40
Therefore, 40 cars will be needed to wash by the swim team to earn $300.
1) The amount of money the swim team charged for each car that it washed is; $5 per car
2) The amount of money that the swim team had in its account before the car wash is; $100
3) If the team wants to earn $300, then number of cars they need to wash is; 40 cars
We know that formula for slope between two points is;
m = (y₂ - y₁)/(x₂ - x₁)
Let us take 2 coordinates from the given graph which are;
(10, 150) and (30, 250)
Thus;
m = (250 - 150)/(30 - 10)
m = 100/20
m = 5
Now, the equation of a line in slope intercept form is;
y = mx + c
where;
m is slope
c is y-intercept
From our graph, the y-intercept is 100. Thus, equation of the line of the graph is;
y = 5x + 100
A) From our equation y = 5x + 100, we can say that number of cars are x and as such amount charged per car is $5 per car.
B) The amount of money the swim team had before washing cars is when the value of x is 0. Thus;
y = 5(0) + 100
y = $100
C) The team wants to earn $300 and so we will plug 300 for y into y = 5x + 100 to get;
300 = 5x + 100
5x = 300 - 100
5x = 200
x = 200/5
x = 40 cars.

The three angles of a triangle add up to 180°. If two angles are 57and 8what is the measure of the third angle?
39
96
141°
123
Answer:
39
Step-by-step explanation:
assuming the angles are 57 & 84
141 + 57 > 180
123 + 57 = 180 (no room for an 8)
96 + 57 = 153
180 - 153 = 27 (an 8 doesn't work for this answer)
57 + 39 = 96
180 - 96 = 84 ( we have a winner!)
A farmer has found that in a typical year they earn $75000 from their harvest. In a wet year they earn $48000, and in a drought they earn $26000. If the probability of a wet year is 0.30 and the probability of a drought is 0.20 find the mean amount this farmer will make from their harvest over a long period of years. If the farmer has the option of buying insurance for $2000 a year that pays $20000 in a year of a drought, does it make sense financially to buy the insurance? Justify.
Answer:
1. The mean amount that this farmer will earn over a long period of years is:
$57,100
2. It makes sense financially for the farmer to buy the insurance. In a year of drought, he earns only $5,200. If he spends on insurance premium, his earnings are reduced by $2,000 to $3,200 but the insurance reimbursement will take his overall net earnings to $23,200 ($3,200 + $20,000). Incurring the insurance expense is highly justified.
Step-by-step explanation:
Earnings in a typical year = $75,000
Earnings in a wet year = $48,000
Earnings in a drought = $26,000
Pro
Typical Wet Drought
Earnings $75,000 $48,000 $26,000

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.
