Answer: This comes out to be 0.1031.

Step-by-step explanation:

in this case, we are given that the rate of power cuts in the city is 3/day, so the rate parameter for our Poisson distribution is $\lambda=3$. We want to find the probability that there are at least 7 cuts but at most 4 cuts in a given day. This means we need to find the probability that $k=7$, $k=8$, $k=9$, ..., $k=4$. We can use the formula for the probability mass function to find the probability for each of these values of $k$ and add them together to get the total probability.

We can use the confidence interval formula to estimate how much the drug will lower a typical patient's systolic blood pressure with 80% confidence.

The confidence interval formula is:

Sample mean ± (t-score × standard error)

Where the t-score is calculated from the t-distribution using the number of degrees of freedom (n-1) and the confidence level (80%).

Using the given information, we can calculate the t-score as follows:

t-score = 1.711 (for 80% confidence level and 28 degrees of freedom)

Therefore, the confidence interval is:

55.9 ± (1.711 × (7.4/√29))

= 55.9 ± 4.125

So, with 80% confidence, we can say that the drug will lower a typical patient's systolic blood pressure by between 51.8 and 60.0.

What is center of mass?

The unique location where the weighted relative position of the scattered mass adds to zero is known as the center of mass in physics. Here is where a force may be applied to produce a linear acceleration without also producing an angular acceleration.

The center of mass is a position defined relative to an object or system of objects. It is the average position of all the parts of the system, weighted according to their masses.

The number of students and adult ticket sold are 988 and 758 respectively .

Students pay $2 per ticket and adults pay $5 per ticket. The stadium is filled to its capacity of 2000 but 254 of those seats are given free of charge to band members, pep squad members, and faculty members.

The total income from the sale of tickets for the current game is $5766.

The number of student and adult tickets that were sold can be calculated as follows:

let

x = number of student ticket sold

y = number of adult ticket sold

Hence, using equation,

Students pay $2 per ticket and adults pay $5 per ticket and the total total sale is 5766.

2x + 5y = 5766

The stadium is filled to its capacity of 2000 but 254 of those seats are given free. This means the actual number of people that paid for the seats is 2000 - 254 = 1746.

x + y = 2000 - 254

x + y = 1746

Combine the equation

2x + 5y = 5766

x + y = 1746

multiply equation(ii) by 2

2x + 5y = 5766

2x + 2y = 3492

subtract equation(ii) from equation(i)

3y = 2274

y = 2274 / 3

y = 758

x = 1746 - 758

x = 988

Calculate the standard deviation of the (d)

Sd = √(d₁-dbar)²/n-1

Answer:

The sales tax rate is 7.96%.

Step-by-step explanation:

To determine the sales tax rate, we need to first calculate the amount of the discount on the tablet by multiplying the regular price by the discount percentage:

Discount = Regular price * Discount percentage

Discount = $330 * 15%

Discount = $49.50

Next, we can calculate the total price of the tablet before taxes by subtracting the discount from the regular price:

Total price before taxes = Regular price - Discount

Total price before taxes = $330 - $49.50

Total price before taxes = $280.50

Finally, we can calculate the sales tax rate by dividing the total amount of taxes paid by the total price of the tablet before taxes and multiplying by 100% to express the result as a percentage:

Sales tax rate = (Total amount of taxes paid / Total price before taxes) * 100%

Sales tax rate = ($302.94 - $280.50) / $280.50 * 100%

Sales tax rate = $22.44 / $280.50 * 100%

Sales tax rate = 7.96%

Therefore, the sales tax rate is 7.96%.

The pooled proportion is 0.200 and the standard error of the difference in the proportions is 0.0201.

1. The null hypothesis is Pu-Po = 0, which means that the proportion of people under 18 who had accidents is the same as the proportion of people over 18 who had accidents.

2. To calculate the pooled proportion, we first add the total number of people in each group (500 + 600 = 1100). Then we add the total number of accidents in each group (180 + 150 = 330). Finally, we divide the total number of accidents by the total number of people to get the pooled proportion (330/1100 = 0.200).

3. The standard error of the difference in the proportions can be calculated using the formula SE = SQRT(P1*(1-P1)/n1 + P2*(1-P2)/n2), where P1 is the proportion of people under 18 who had accidents, P2 is the proportion of people over 18 who had accidents, and n1 and n2 are the number of people in each group. In this case, P1 = 150/600 = 0.250, P2 = 180/500 = 0.360, n1 = 600, and n2 = 500. Plugging these values into the formula gives us SE = SQRT(0.250*(1-0.250)/600 + 0.360*(1-0.360)/500) = 0.0201.

The values of m and n required to form perfect square trinomials are given as follows:

b) m = 6, n = 9.

c) m = 12, n = 180.

d) m = -7/2, n = 49/16.

Perfect square trinomials are expressions that have either of these two formats:

The term that multiplies x is always the multiplication of 2 by both of the two terms that are added.

Hence in item 1, the expression is completed as follows:

x² - 10x = (x - 5)² - 25 = x² - 10x + 25 - 25

Meaning that m = -10, n = 25.

In item 2, the expression is completed as follows:

x² + 6x = (x + 3)² - 9 = x² + 6x + 9 - 9.

Hence m = 6, n = 9.

In item 3, the expression is completed as follows:

5x² + 60x = 5(x² + 12x) = 5(x + 6)² - 180 = 5(x² + 12x + 36) - 180 = 5(x² + 12x + 180 - 180).

Hence m = 12, n = 180.

In item 4, the expression is completed as follows:

2x² - 7x = 2(x² - 7/2x) = 2(x² - 7/4x)² - 49/32 = (2x² - 7/2x + 49/16 - 49/16).

The initial jump was 5.7m and the second jump is 6.2m

By using the percentage increase formula, we can write

         Percentage increase = (final value - initial value)/|Final value| * 100

                                             = ((6.2 - 5.7)/6.2)*100

As per the concept of hypothesis, the value of p is 0.47 the value of the static hypothesis is 4.3893 and the statistical division when the alpha = 0.05 is 0.1085.

What is meant by hypotheses?

in math, hypotheses refers a an assumption, an idea that is proposed for the sake of argument so that it can be tested to see if it might be true.

Here we have given that, a movie production company is releasing a movie with the hopes of many viewers returning to see the movie in the theater for a 2nd time. The target is to have 40 million viewers and they want more than 40% of the viewers to return to see the movie again.

And they show the movie to a test audience of 140 people.

Of the test audience, 66 people said they would see it again.

And we have to determine, the p-value is, the p-value for the test statistic.

And the statistical division when the alpha = 0.05 and explain the managerial conclusion for this situation.

Based on the question, the null hypothesis is,

H0: P = 3

H1: P > 0.03

Here we know that they show the movie to a test audience of 140 people.

So, n = 140

Here the test audience, 66 people said they would see it again.

So, x = 66

Therefore, the value of p is,

=> 66/140 = 0.47

Then the test hypothesis is,

=> Z = (0.47 - 0.3) / √[(0.3(1 - 0.3))/140]

When we simplify this one, then we get,

=> Z = 4.3893

Therefore, value of the static hypothesis is 4.3893.

Then the p-value = 0.1085 at 5% level of significance.

Here, 0.1085 <  4.3893,

Therefore, the null hypothesis is not rejected.

Therefore, p-value  = 0.1085, and we will not reject the null hypothesis.

So, the value of the static hypothesis is greater than the null hypothesis and the value of p so the value of not rejects the null hypothesis.
