Assume Waterland and Aquataste make a nonbinding, informal agreement that each will produce 250 gallons of water, charge $1.50 per gallon, and evenly split the profit of $750.
If Aquataste sticks to the agreement, Waterland has an incentive to renege on the agreement by producing 350 gallons because Waterland's profits would then increase from $375 to ______
If Aquataste reneges on the agreement and produces 350 gallons, Waterland has an incentive to renege on the agreement by producing 350 gallons because Waterland's profits would increase to _____, which is better than the $312.50 Waterland would earn by sticking with the agreement.
$437.50
If one cheats they will get sell 350 gallons at the new market price of $1.25 (now a total qty of 250+350=600). $1.25*350=$437.50
$350
If Waterland also reneges and produces 350, market qty supplied is now 700 and price is $1. Each firm earns profit of $350 ($1*350). This is better for waterland than before since they were selling the 250 gallons at $1.25 (Profit = 250*1.25=312.50)

When the standard deviation is $1200 and the mean is $8000, the test statistic's result will be -1.804.

A statistic employed in statistical hypothesis testing is known as a test statistic. A test statistic, which can be thought of as a numerical summary of a data set that condenses the data into a single number that can be used to conduct the hypothesis test, is how a hypothesis test is commonly expressed. A number derived from a statistical test of a hypothesis is the test statistic. It displays how closely your actual data fit the distribution predicted by the statistical test's null hypothesis.

Here,

The claimed mean=$8250

The actual mean=$8000

The sample size=75

The standard deviation=$1200

The test statistic,

=(Actual mean-claimed mean)/Standard deviation/√(sample size)

=(8000-8250)/1200/√75

=-250/1200*1/√75

=-1.804

The value of test statistic will be -1.804 when the mean is $8000 and standard deviation is $1200.

The probability that you have seen both the red and green marbles at least once is 0.3104

Given,

1/5 chance of winning a marble of any color in a drawing.

Every draw is independent and has the same probability because the marbles are replaced.

Calculating = 1- the likelihood of not receiving both red and green marbles in any of the four draws yields the same result as P, the probability of receiving both red and green marbles at least once (Q).

The union of the following three examples represents ways to not receive both red and green in all four draws:

(1)

Probability of no red and no green in a draw = 3/5.

Probability of no red and no green in 4 draws,

Q1 = 3/5 * 3/5 * 3/5* 3/5 = 81/54

The probabilities are multiplied as each draw is independent and has the same probabilities.

(2)

The probability of no red and 1 green in 4 draws is given by binomial probability.

= (4 3) (1/5)(3/5)³ = (4 * 3³)/5¹ = 108/5⁴

The probability of no red and 2 green in 4 draws is given by binomial probability.

= (4 2) (1/5)²(3/5)² == (6 * 3²)/54 = 54/5⁴

The probability of no red and 3 green in 4 draws is given by binomial probability.

= (4 3) (1/5)³(3/5) == (4 * 3)/5¹ = 12/5⁴

The probability of no red and 4 green in 4 draws is given by binomial probability.

= (4 4) = 1 * 1/5¹ = 1/5⁴⁴

Q2= sum of all 4 above probabilities.

Q2 (108 +54 + 12+1)/5 = 175/5⁴

(3)

This probability is the same as in Q2. Q3 = 175/5⁴

Therefore the probability of not seeing both red and green at all,

Q = Q1 + Q2 + Q3.

   = 81 +175 + 175/5⁴ = 413/5⁴

Finally, the probability of getting both red and green at least once,

P = 1 - Q

  = 1-413/5⁴

  = (625 431)/625

  = 194/625

  = 0.3104.

The answer is 0.3104.

Step-by-step explanation:

The times when Hayden made the bracelets in this situation don't matter. All that matters in this problem is how many he made. Since it tells you that he made them for 5 days, you would multiply the number of bracelets by the days, to get the total. (Or write the equation like so: 5*(2+4))

And of course, since they are divided into groups as the last step, we have division.

The coordinates of the midpoint are (-1, 3.5) and the distance of AC is 26.25 units.

We know that for a segment whose endpoints are (x₁, y₁) and (x₂, y₂), the coordinates of the midpoint are:

( [x₁ + x₂]/2, [y₁ + y₂]/2)

In this case, the endpoints are:  (3, -9) and (-5, 16), then the midpoint is:

M = ( [3 - 5]/2, [-9 + 16]/2)

M = (-1, 3.5)

The distance between two points (x₁, y₁) and (x₂, y₂) is:

d = √( (x₁ - x₂)^2 + (y₁ - y₂)^2)

The volume of the vanilla ice cream in the cone is 4.18 cubic inches

The diameter of the cone = 2 inches

The radius of the cone = 2/1

= 1 inches

The height of the cone = 6 inches

The volume of the cone = (1/3) × π × r^2 × h

Substitute the values in the equation

= (1/3)π × 1^2 × 6

= 6.28 cubic inches

The ratio of  vanilla and chocolate ice cream = 2:1

2x + x = 6.28

3x = 6.28

x = 6.28 / 3

x = 2.09

The volume of vanilla ice cream = 2x

= 2×2.09

Answer:

There are 2 stars

Step-by-step explanation:

There are 29 items in total.

As we are given the number of two of the items(nutcrackers and snowmen)we can easily find the number of the last item(stars) by subtracting the number of nutcrackers and snowman by the number of total items.(29)

So the solution would be :

29 - (13 + 14) = number of stars

==> add 13 and 14

29 - 27 = number of stars

==> simplify

2 = number of stars

Using the z-score a randomly selected Endure All battery has a 10.56% chance of lasting more than 550 hours.

How closely a value relates to the mean of a set of values is measured using a Z-score.

Z-score is calculated using standard deviations from the mean.

When a data point's Z-score is 0, it indicates that its entire score is equal to the mean score.

So, how far the raw score deviates from the mean is determined using the Z score.

These steps are used to determine the Z score:

z = (x - μ)/σ

We know that:  x > 550 and μ = 500, σ = 40

z = 550 - 500 / 40

z = 1.25

Using the normal distribution graph as a guide:

P(z > 1.25) = 1 - P(z < 1.25)

P(z > 1.25) = 1 - 0.8944

P(z > 1.25) = 0.1056

Therefore, using the z-score a randomly selected Endure All battery has a 10.56% chance of lasting more than 550 hours.

The required Interest Rate Compounded Daily​ (365 Days/Year) is 7.227%.

Interest on interest, or compound interest, is the adding of interest to the principle sum of a loan or deposit. It's the outcome of reinvesting interest rather than paying it out, so that interest is received on the principal plus previously collected interest in the next quarter.,

[tex]A = P(1+ \dfrac{r}{n})^{nt}[/tex]

where A is the final amount

P is the principal amount

r is the rate of interest

n is the number of times interest is charged in a year

t is the number of years

Given that interest Rate Compounded Daily​ (365 Days/Year) is required for a ​$23,000 Investment to grow To $35,500 In 6 ​Years. Therefore, we can write,

[tex]A = P(1+\dfrac rn)^{n \times t}[/tex]

[tex]35,500 = 23,000(1+\dfrac{r}{365})^{365 \times 6}\\\\\dfrac{35,500}{23,000} = (1+\dfrac{r}{365})^{2190}\\\\1.543478 = (1+\dfrac{r}{365})^{2190}\\\\1.000198 = 1+\dfrac{r}{365}\\\\\dfrac{r}{365} = 1.000198 - 1\\\\\dfrac{r}{365} = 0.000198[/tex]

r = 1.000198 x 365

Using the probability formula, the number of diamonds needed to make the game fair is determined by option (B) 6.

Assume that there are a finite number of elementary events that are all equally likely to occur in the sample space of the experiment under consideration.

So let's say we want to determine the likelihood of an occurrence E.

So, the value of diamonds has to be:

The expected number of points that one can lose should equal the expected number of points that one can acquire for the game to be fair.

So, in order for the game to be fair, we need:

Expected points earned by selecting a diamond minus anticipated points lost by selecting a diamond.

If we choose a diamond, let's say we obtain P points.

Let X represent the random variable that records the player's score for each individual draw.

13/52 = 1/4 is the probability of selecting a diamond from a deck of 52 cards.

This is due to the fact that there are only 13 ways to choose a diamond out of the total 52 ways to choose a card.

So, the likelihood of receiving P points is 1/4, or 0.25.

The odds of not getting a diamond equal 1 minus the odds of getting a diamond equal 1 minus 0.25, which equals 0.75.

The points we receive when we don't acquire a diamond are -2. (negative since we actually lose it, so we can take it as a negative gain).

E(X) = expectation of X = 0 is therefore required (since the negative points of loosing would equate to positive point of winning, thus, making the expected overall score 0, thus, keeping it a fair game.)

We now have:

When choosing a non-diamond card, P(X = -2) equals 0.75; when choosing a diamond card, P(X = p) equals 0.25.

There are only possible values for X.

The result is:

E(X) = -2*p(X=-2)+p*p(X=p)

E(X) = -2*0.75+p*0.25

0=-1.5+0.25p

p = 1.5/0.25 = 6

Therefore, using the probability formula, the number of diamonds needed to make the game fair is determined by option (B) 6.
