Answer:

To convert a fraction into a decimal, divide the top number by the bottom number. What about with denominators that don't divide into 10, 100 or 1000, such as 7? You still divide the denominator into the numerator, no matter what the numbers are.

Jody decides to ride her bike from her house to the park. The distance she travels on her bike, in kilometers, is equal to the function f(t), where t represents the number of hours she has been riding her bike. Jody rides her bike from her house to the park. Before Jody leaves her house f(0) = 0, and when Jody reaches the park f(2) = 30. From the information given, determine whether each statement is a correct interpretation that can be made about Jody's bike ride. Select Correct or Incorrect for each statement. Correct Incorrect It takes Jody 2 hours to bike to the park. The park is located 2 kilometers from Jody's house. When Jody is at her house she has biked for 0 hours.

Answers

Answer:

A)It takes Jody 2 hours to bike to the park.- Correct

B)The park is located 2 kilometers from Jody's house.- Incorrect

C) When Jody is at her house she has biked for 0 hours.- Correct

Step-by-step explanation:

We are given that The distance she travels on her bike, in kilometers, is equal to the function f(t), where t represents the number of hours she has been riding her bike.

f(t)= Distance covered in t hours

t = time in hours

Jody rides her bike from her house to the park. Before Jody leaves her house f(0) = 0

So, Distance covered in 0 hours is 0 km

So, When Jody is at her house she has biked for 0 hours

Jody reaches the park f(2) = 30.

So, Distance traveled in 2 hours is 30 km

So, It takes 2 hours to reach park

A)It takes Jody 2 hours to bike to the park.- Correct

B)The park is located 2 kilometers from Jody's house.- Incorrect

C) When Jody is at her house she has biked for 0 hours.- Correct

Podemos calcular la profundidad d

d=5h

Cuántas horas tarda en acumularse 1
centímetro de nieve en el jardín de Harper?


Cuántos centímetros de nieve se acumulan por hora?

Answers

Answer:

a) Cuántas horas tarda en acumularse 1

centímetro de nieve en el jardín de Harper?

0.508 horas o 30.48 minutos

b) Cuántos centímetros de nieve se acumulan por hora?

5 cm

Step-by-step explanation:

a) ¿Cuántas horas se necesitan para acumular 1 pulgada de nieve en el jardín de Harper?

1 pulgada de nieve = 2.54 cm de nieve

d = 5 × h

2.54 = 5 h

h = 2.54 / 5

h = 0.508 hora

Convertir a minutos = 0.508 horas × 60 minutos

= 30.48 minutos.

Por lo tanto, se necesitarían 0.508 horas o 30.48 minutos para acumular 1 pulgada de nieve en el jardín de Harper.

b) ¿Cuántos centímetros de nieve se acumulan por hora?

d = 5 h

Por hora = 1 hora

d = 5 × 1

d = 5 cm

Por tanto, se acumulan 5 cm de nieve por hora.

The prostate-specific antigen (PSA) test is a simple blood test to screen for prostate cancer. It has been used in men over 50 as a routine part of a physical exam, with levels above 4 ng/mL indicating possible prostate cancer. The test result is not always correct, sometimes indicating prostate cancer when it is not present and often missing prostate cancer that is present. Suppose that these are the approximate conditional probabilities of a positive (above 4 ng/ml) and negative test result given cancer is present or absent. In a large study of prostate cancer screening, it was found that about 6.2% of the population has prostate cancer. Draw a tree diagram for selecting a person from this population (outcomes: cancer present or absent) and testing his blood (outcomes: test positive or negative).

Answers

The missing table for the Test Result can be expressed as:

                              Test Result

Use the residual plot to determine if this linear model is appropriate.

Answers

Answer:

The linear model is not appropriate.

Step-by-step explanation:

In regression, the difference amid the observed-value of the dependent-variable (y) and the predicted-value ([tex]\hat y[/tex]) is known as the residual (e).

[tex]e=y-\hat y[/tex]

A residual plot is a graphical representation of the residuals on the y-axis and the independent variable on the x-axis. If the data-points on the residual plot are randomly spread around the x-axis, a linear regression model is appropriate for the data. And if the residual plots shows a non-random or a U or inverted U pattern, a nonlinear model is more appropriate for the data.

The residual provided shown an inverted U pattern. That is the points are not scattered around he graph.

Thus, the linear model is not appropriate.

A residual plot for the nutrition data would display the residuals on the y-axis and the age on the x-axis.

The residual plot is not appropriate for a linear model.

From the residual plot (see attachment), we can see that the points on the residual plot follows a curved pattern.

For a residual plot to be a linear model, the points on the plot must be at random on the horizontal axis of the plot.

This means that, the residual plot is not appropriate for a linear model.

What is the value of g(3) when g(2) = 21–2?

g(3)=31.5-3

Step-by-step explanation:

first you want to find g(1) or g(x). all you have to do for this is divide every number by two, since 2/2 is 1.

g(1)=10.5-1

now to find g(30 you just multiply it all by 3.

g(3)=(10.5-1)*3

g(3)=31.5-3.

One car dealer sells a car with a $500 down payment and payments of $250 per month. Another car dealer sells the same type of car with no down payment and monthly payments of $300 per month. After how many months will the buyers have paid the same amount? Use m for your variable

Answers

Answer:

By month 10 both buyers will have paid the same amount of 3,000.

Step-by-step explanation:

The equation would be 500 + 250m = 300m. If you put 10 in for m you get the same amount on both sides of the equation.

500 + 250m = 300m

500 + 250(10) = 300(10)

500 + 2,500 = 300(10)

3,000 = 300(10)

3,000 = 3,000

A line contains points M(1, 3) and N(5, 0). What is the slope of MN?

Answers

Answer:

-3/4

Step-by-step explanation:

y2-y1/x2-x1

0-3/5-1

A line contains points M(1, 3) and N(5, 0). The slope of MN is -3/4.

What is the slope of the line?

A line's slope provides information on the steepness and direction of the line. By calculating the difference between the coordinates of the two locations, (x1,y1) and (x2,y2), it is simple to calculate the slope of a straight line between them.

The slope, m, of the line, is calculated through the equation,

The formula used to find the slope is,

m = (y2 - y1)/ (x2 - x1)

Where (x1, y1) and (x2, y2) are the points

The given points on the line are:

M(1, 3) and N(5, 0)

Substituting it in the formula,

m = (0 - 3)/ (5 - 1)

m = -3/4

Therefore, the slope of MN is -3/4.
