Step-by-step explanation:

The distance from Jim's house to the mall is given as follows:

11.25 miles.

Suppose that we have two points with coordinates given as follows:

\((x_1, y_1)\) and \((x_2, y_2)\)

Then the equation for the distance between these two points is given as follows:

\(D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

The coordinates are given as follows:

Hence the distance is given as follows:

\(D = \sqrt{(17 - 8)^2+(13 - 1)^2}\)

D = 15 units.

Each unit represents 0.75 miles, hence the distance in miles is given as follows:

15 x 0.75 = 11.25 miles.

The problem is given by the image presented at the end of the answer.

Based on the information provided, the circle graph represents the preferences of the citizens for their favorite type of pet. we can calculate the number of citizens who chose cats by multiplying the total number of citizens (130,000) by that percentage. If the graph shows that 40% of citizens chose cats, then the calculation would be 130,000 * 0.40 = 52,000 citizens who chose cats as their favorite pets.

According to the circle graph, we can see that the blue section represents the percentage of citizens who chose cats as their favorite type of pet. To find out the actual number of citizens who chose cats, we need to use the information that 130,000 citizens answered the question.

First, we need to determine what percentage of citizens chose cats. From the graph, it looks like the blue section represents about 35% of the total.

To calculate this percentage as a decimal, we divide 35 by 100:

35/100 = 0.35

Now we can use this decimal to find out how many citizens chose cats:

0.35 x 130,000 = 45,500

Therefore, approximately 45,500 citizens chose cats as their favorite type of pet.

System H is linear equation , causal and time invariant but not stable. The impulse response is y(t) = 4 cos[6(t + 1)].

System H is a mathematical system that describes the relationship between the input x(t) and the output y(t) as y(t) = 4 cos[6(t + 1)]x(t). This system is linear because the output is a linear combination of the inputs. A linear system is one in which the output is directly proportional to the input. This system is also causal because the output at a given time depends on the past and present inputs. This means that the output cannot be affected by future inputs. This means that the system will produce the same output regardless of when the input is applied. However, System H is not stable because the output will increase in magnitude as the input increases. This means that the system will not remain bounded as the input increases. The impulse response of this system is y(t) = 4 cos[6(t + 1)]. This means that the output at time t is proportional to the impulse applied at time t.

The shape of the normal distribution is bell shape and it is also symmetrical from the left and right sides about the origins (mean).

What is a normal distribution?

A normal distribution is a function on some random variables, which represent the set of all those random variables in a symmetrical bell shape about the mean value.

It shows that the probability of occurrence of some data which is distributed over a function is more at or around the mean.

It is also known as probability distribution curve.

The normal distribution has two parameters:

What is the shape of the normal distribution?

The normal distribution curve is at it's peak at the mean value. This shows that the probability of occurrence of the data or value is more concentrated or distributed about the mean. It is also symmetric about the mean. As we more further from the mean, we see that the normal distribution curve gradually decreases showing that the probability of occurrence of the data or the values decreases. The shape that this curve forms is like a bell-shaped. So the shape of normal distribution is bell shape.

Hence, the shape of the normal distribution is bell shape and it is also symmetrical from the left and right sides about the origins (mean).

The probability that a family has more than 3 cars among the 100 families polled is approximately 0.11 or 11%.

From the given probability distribution, we can add up the probabilities of owning 4 or 5 vehicles, which are 0.36 and 0.3, respectively. Thus, the probability of a family owning 4 or 5 vehicles is 0.36 + 0.3 = 0.66. To find the probability of a family owning more than 3 cars, we subtract the probability of owning 0, 1, 2, or 3 vehicles from 1, which is the total probability of owning any number of vehicles.

Thus, the probability of owning more than 3 cars is 1 - (0.5 + 0.45 + 0.4 + 0.36) = 0.11 or 11%.

It is important to note that this calculation assumes that the given probability distribution accurately represents the population of interest and that the sample of 100 families is a representative sample.

Answer:

Karina is 58 1/8 jane is 59 13/40

Step-by-step explanation:

The value of the integral is 9. To evaluate the integral: ∫[1,8] \(x^{(-2/3)}\) dx

We can use the power rule of integration. Specifically, we have:

∫ \(x^{(-2/3)}\) dx = 3\(x^{(1/3)}\) / (1/3) + C = 9\(x^{(1/3)}\) + C

where C is the constant of integration.

Applying this formula to the given integral, we have:

∫[1,8] \(x^{(-2/3)}\) dx = [9x^(1/3)] [1,8] = 9(\(8^{(1/3)}\) - \(1^{(1/3)}\)= 9(2 - 1) = 9

Therefore, Kenji's profit is maximized at 5 shirts with a marginal cost of $12. The profit-maximizing quantity corresponds to the intersection of the marginal cost and marginal revenue curves.

Kenji's profit is maximized when he produces 5 shirts. At this level of production, the marginal cost of the last shirt he produces is $12, which is less than the price Kenji receives for each shirt he sells. The marginal cost of producing an additional shirt is $18, which is more than the price Kenji receives for each shirt he sells. Therefore, Kenji's profit-maximizing quantity corresponds to the intersection of the marginal cost and marginal revenue curves. Because Kenji is a price taker, this last condition can also be written as producing where marginal cost equals price.

Answer:

The Gold team has 8 swimmers and the silver team also has 8 swimmers.

Step-by-step explanation:

Let T be the total number of swimmers on the Gold team. Since, the Gold team has a 2:3 ratio of 11 year olds to 12 year olds, the number of 11 year old is T' = 2/(2 + 3) × T = 2T/5 and the number of 12 year olds is T" = 3/(2 + 3) × T = 3T/5.

The silver team has a 3:8 ratio of 11 year olds to the total swimmers. Let T₁ be the number of 11 year old swimmers in the silver team. So, from the ratio 3:8, the number of 11 year old swimmers in the silver team is 3 and the total number of swimmers in the silver team is 8.

Since the number of 11 year old swimmers in both teams are the same, then

2T/5 = 3

T = 3 × 5 ÷ 2

T = 15/2

T = 7.5

T≅ 8

So, the Gold team also has 8 swimmers.

So, the Gold team has 8 swimmers and the silver team also has 8 swimmers.

This is because higher the predictor variable (like SAT scores), the higher the GPA of the student is expected to be. Therefore, we can expect a positive relationship between predictor and target variables, and the slope of the linear regression line should be positive.

a. The target variable can be the GPA (Grade Point Average) of the student. GPA is a continuous-valued variable that measures the success of a student in a meaningful way and can be easily collected (in an automated manner) by the university.

b. The target variable (GPA) is a continuous-valued variable.

c. The possible variable that can act as a predictor for the target variable (GPA) can be SAT scores, grades in the previous schools, and other academic records of the student.

d. Before looking at the data, it is reasonable to consider a linear model for the data. Linear regression is a simple and effective method to model the relationship between two continuous variables. Since we chose the GPA as a target variable which is continuous, we can expect the slope to be positive.

Answer:

Step-by-step explanation:

To solve the inequalities -2x + 4 < 8 and 3x + 4 ≤ -5, we will solve them individually and then represent the solutions on a number line.

For the first inequality, -2x + 4 < 8, we will isolate x:

-2x + 4 - 4 < 8 - 4

-2x < 4

Dividing both sides by -2 (remembering to reverse the inequality when multiplying/dividing by a negative number):

x > -2

For the second inequality, 3x + 4 ≤ -5, we isolate x:

3x + 4 - 4 ≤ -5 - 4

3x ≤ -9

Dividing both sides by 3:

x ≤ -3

Now we represent the solutions on a number line. We mark -2 with an open circle (since x > -2), and -3 with a closed circle (since x can be equal to -3). Then we shade the region to the right of -2 and include -3 to represent the solutions.
