The probability that the firm receives 2 or more complaints in a day is 0.33.

This can be calculated using the Poisson distribution formula. The Poisson distribution is a probability distribution used to calculate the probability of an event occurring a given number of times in a fixed interval of time or space.

It is based on the assumption that the rate of occurrence of an event is constant.

In this case, we are looking at the probability of the firm receiving 2 or more complaints in a day. Let x = 2, where x is the number of complaints in a day. Then, the Poisson distribution formula is: P(x) = (e-λ λx) / x!

Where e = 2.71828 and λ = 3 (the rate of complaints per day).

Plugging in the values, we get: P(2) = (2.71828-3 * 32) / 2! = 0.33. Therefore, the probability that the firm receives 2 or more complaints in a day is 0.33.

The statement that is true for the two equations Equation A: 3(2x-5)=6x-15 and Equation B: 2+3x=3x-4 is that "Equation

A has an infinite number of solutions and Equation B has no solution".Explanation:To find the solution for the two equations, we will solve for each equation separately. Solution of equation A: 3(2x - 5) = 6x - 15 ⇒ 6x - 15 = 6x - 15 ⇒ 6x - 6x = -15 + 15 ⇒ 0 = 0

This is a true equation, which means that it is an identity. The equation can be written as 0 = 0. Any value that is inserted in this equation will result in a true statement. Hence the equation A has an infinite number of solutions. Solution of equation B: 2 + 3x = 3x - 4 ⇒ 2 + 4 = 3x - 3x - 4 ⇒ 6 = -4This is a false equation. It means that there is no value that can be inserted into the equation to make it a true statement. Therefore, the equation B has no solution. Hence the statement that is true for the two equations Equation A: 3(2x-5)=6x-15 and Equation B: 2+3x=3x-4 is that "Equation A has an infinite number of solutions and Equation B has no solution".

The amount of fencing needed to surround the walkway of a garden that is 5 feet by 6 feet is 28 feet. Let us first calculate the perimeter of the garden by adding all the sides together.

The garden is 5 feet by 6 feet, so its perimeter is:2(5) + 2(6) = 10 + 12

= 22 feet

Now, we have to add the walkway's width around the garden to the dimensions of the garden. Since the walkway is 2 feet wide on all sides, we add 4 feet (2 feet on each side) to the width of the garden and 4 feet to its length. Therefore, the new dimensions of the garden, including the walkway, are:

5 + 2 + 2 = 96 + 2 + 2

= 8

So the dimensions of the garden, including the walkway, are 9 feet by 8 feet.Now, we need to calculate the perimeter of the walkway. The perimeter is calculated as follows:

2(9) + 2(8) = 18 + 16

= 34 feet.

The question asks for the amount of fencing required to surround the walkway. Therefore, we subtract the perimeter of the garden from the perimeter of the walkway to obtain the required amount of fencing.

34 - 22 = 12 Therefore, the amount of fencing needed to surround the walkway of a garden that is 5 feet by 6 feet is 28 feet.

When x = 1, y = -6

Step-by-step explanation:

Given:

y = -3x - 3

Fill in the table using the following value for x

When x = -2

y = -3x - 3

y = -3(-2) - 3

y = 6 - 3

Answer:

To rent a jet ski you need to pay $50 and to rent a kayak you need to pay $20

Step-by-step explanation:

Since both shops charge the same amount for each kind of vehicle, we will assign variables to the their cost. The cost of a jet ski will be "x" and the cost of the kayak will be "y". Therefore we can create a system of equations as shown below:

Will's shop:

12*x + 9*y = 780

Fun Rentals:

7*x + 11*y = 570

\(\left \{ {{12x+ 9y=780} \atop {7x + 11y =570}} \right.\\\)

We can isolate "x" on the second equation, we have:

\(x = \frac{570 - 11y}{7}\)

Applying this value on the first equation:

\(12[\frac{570 - 11y}{7}] + 9y = 780\\\frac{6840 - 132y}{7} + 9y = 780\\\frac{6840 - 132y + 63y}{7} = 780\\ 6840 - 132y + 63y = 5460\\6840 - 69y = 5460\\69y = 1380\\y = 20\)

Applying the value of "y" we found on the "x" equation above, we have:\(x = \frac{570 - 11*20}{7}\\x = 50\\\)

Therefore to rent a jet ski you need to pay $50 and to rent a kayak you need to pay $20

A positive integer y is a whole number by definition, so we are essentially being asked how many positive integers there are. There are infinitely many positive integers, so the answer to the question is also infinity.

A positive integer y is a whole number if it isn't a bit or a numeric. In other words, it's a number that can be expressed without using  fragments or numbers, and can be written as a finite sum of positive integers. For  illustration, 2, 5, and 10 are whole  figures, but3/4,1.5, and √ 2 are not.   To determine how  numerous different values of y are whole  figures, we need to understand the  parcels of whole  figures.

Whole  figures have two main  parcels they're closed under addition and  addition. This means that when you add or multiply two whole  figures, the result is always a whole number. For  illustration, 2 3 =  5 and 2 × 3 =  6, both of which are whole  figures.   To find how  numerous different values of y are whole  figures, we can start with the  lowest possible value of y, which is 1.

Approximately 1 tub of yogurt was taken as a sample.

To solve this problem, we can use the concept of the standard normal distribution and z-scores.

First, we calculate the z-score for the weight of 0.88 lb using the formula:

\(z = (x - \mu) / \sigma\)

where x is the observed weight,  \(\mu\) is the mean weight, and  \(\sigma\)  is the standard deviation.

In this case, x = 0.88 lb, \(\mu\) = 1.0 lb, and \(\sigma\) = 0.06 lb.

z = (0.88 - 1.0) / 0.06

z = -0.12 / 0.06

z = -2

Next, we look up the corresponding cumulative probability for z = -2 in the standard normal distribution table. The table gives us a cumulative probability of approximately 0.0228.

Since we want to know how many tubs of yogurt weighed less than 0.88 lb, we are interested in the area to the left of the z-score -2. This area represents the proportion of tubs that weigh less than 0.88 lb.

Now, we can use the inverse of the cumulative distribution function (CDF) to find the corresponding z-score for the cumulative probability of 0.0228. This will help us determine the number of tubs that correspond to this area.

Using a standard normal distribution table or a calculator, the inverse CDF for a cumulative probability of 0.0228 gives us a z-score of approximately -2.05.

Finally, we can calculate the number of tubs of yogurt taken as samples by rearranging the z-score formula:

\(z = (x - \mu) / \sigma\)

Rearranging for x:

\(x = z * \sigma + \mu\)

x = -2.05 * 0.06 + 1.0

x = -0.123 + 1.0

x \(\approx\) 0.877

Since the weight of each tub is 1.0 lb, the calculated value of x (0.877) represents the proportion of tubs that weighed less than 0.88 lb.

To determine the number of tubs, we divide the observed weight (0.88 lb) by the calculated value (0.877):

Number of tubs = \(0.88 / 0.877 \approx 1\)

Therefore, approximately 1 tub of yogurt was taken as a sample.

To calculate the inclusion probability for unit 6 (PSU level) in the first stage of PPS without replacement, we need to divide the number of sampling units in the population by the total number of sampling units selected in the first stage.

Looking at the provided data, we can see that there are a total of 10 sampling units (Mi) in the dataset.

In PPS without replacement, the first sampling unit is selected with certainty. So, the inclusion probability for unit 6 (PSU level) is:

Inclusion probability = 1 / Total number of sampling units selected in the first stage

                    = 1 / 10

                    = 0.1

\(Sin\theta = \frac{\sqrt{2}}{-2}\)                                                [Dividing both sides by -2]

\(Sin\theta = \frac{-1}{\sqrt{2}}\)

So the area of the base of the solid is 16 square units.

The base of a solid is the region enclosed by y=-x^2/9 4 and y=0. This region can be found by finding the intersection points of these two equations and then integrating the difference between the two functions.

First, we need to find the intersection points of these two equations. To do this, we can set the two equations equal to each other and solve for x:

y=-x^2/9 4 = y=0

x^2/9 4 = 0

x^2 = 36

x = ±6

So the intersection points are (6,0) and (-6,0).

Next, we need to find the area of the region between these two functions. This can be done by integrating the difference between the two functions:

∫(-x^2/9 4 - 0)dx from -6 to 6

= ∫(-x^2/9 4)dx from -6 to 6

= (-1/9)∫x^2dx from -6 to 6

= (-1/9)(x^3/3) from -6 to 6

= (-1/9)(216/3 - (-216/3))

= (-1/9)(144)

= -16

So the area of the base of the solid is 16 square units.
