A fixed ratio schedule is a type of reinforcement schedule in which a response is reinforced after a specific number of responses. In this case, the response of putting money in the machine is reinforced after every 1 response.

If each time you put a dollar in a vending machine you get a snack, then your response is reinforced according to a fixed ratio schedule.

Variable interval, fixed interval, and variable ratio schedules are all different types of reinforcement schedules that are based on different criteria. A variable interval schedule is a type of reinforcement schedule in which a response is reinforced after a random interval of time. A fixed interval schedule is a type of reinforcement schedule in which a response is reinforced after a fixed interval of time. A variable ratio schedule is a type of reinforcement schedule in which a response is reinforced after a random number of responses.

Step-by-step explanation:

a: circumference = 2pi x r

2 x pi x (8)

= 16pi = 50.27

option A

b: Option D

Answer:

A- 50.24

D- the ratio of the circumference of a circle to its diameter

Step-by-step explanation:

circumference (c) = 2πr (2 times pi times radius)

they give you the radius which is 8

c= 2πr

c= 2π(8)

c=16π

you can see all the answers they give you are numbers so you can assume they are rounding pi to 3.14

c=16(3.14)

c=50.24

-------------------------

the ratio of the circumference of a circle to its diameter

you can test this

c:d = π

use example from earlier

50.24: 8(2) = π  ?             multiply by 2 because radius times 2 is diameter

50.24: 16 = π  ?

50.24/ 16 = π  ?

The term "mean" or "average" refers to a statistical measure that describes the central value of a set of data.

It is found by adding all the numbers in a set and dividing the sum by the total number of items in the set. The mean is a valuable tool in interpreting and comparing sets of data. Given below are the solutions to the problems presented:

a. Mean (average) = (24 + 45 + 38 + 56 + 27)/5= 190/5= 38

b. Mean (average) = (24 + 31 + 17 + 39 + 9 + 17)/6= 137/6= 22.83

c. Mean (average) = (125 + 136 + 174 + 116 + 164)/5= 715/5= 143

d. Mean (average) = (3.8 + 9.2 + 6.7 + 11.5)/4= 31.2/4= 7.8e.

Mean (average) = (7.3 + 7.5 + 7.0 + 8.1 + 8.0)/5= 38.9/5= 7.78

Therefore, the mean (average) of the given sets of numbers is:

a. 38 b. 22.83 c. 143 d. 7.8 e. 7.78

The expression which is equivalent to -10 is the option b, -3 - 7.

Explanation:

We can use subtraction and addition of integers to get the value of the given expression. We can write the given expression as;

-3 - 7 = -10 (-3 - 7)

The addition of two negative integers will always give a negative integer. When we subtract a larger negative integer from a smaller negative integer, we will get a negative integer.

If we add -3 and -7 we will get -10. This makes the option b the correct answer.

The probability of throwing an odd number with a normal dice is 1/2

When rolling a normal six-sided B, there are six equally likely outcomes: 1, 2, 3, 4, 5, and 6. Out of these six numbers, three of them (1, 3, and 5) are odd numbers. Thus, there are three favorable outcomes (odd numbers) out of a total of six possible outcomes.

To calculate the probability, we divide the number of favorable outcomes by the total number of possible outcomes. In this case, the probability of throwing an odd number is 3/6, which simplifies to 1/2.

This means that there is a 50% chance of rolling an odd number with a normal six-sided die. In other words, if you roll the die many times, you can expect that approximately half of the outcomes will be odd numbers.

Answer:

Step-by-step explanation:

Answer:

Method 1: $12.75

Method 2: $9

Step-by-step explanation:

method #1: 32-15 is $17

In order to take off a percentage, we must find that percentage of the amount. To do this, we must multiply by the percent in decimal form, so

\(17 \times .25 = 4.25\)

Now, this amount just represents the percent of 17 we would take off, so we must take that amount off.

\(17 - 4.25 = 12.75\)

We would pay $12.75

Method #2:

There are a few ways to do this with 25%. we know 25% is 1/4, and 1/4 or $32 is 8. so we can simply take that off from the start. Otherwise, we can follow the method above as follows

\(32 \times .25 = 8\)

Again, this is the amount off so we must subtract.

\(32 - 8 = 24\)

now, we subtract 15.

\(24 - 15 = 9\)

We would pay $9 using this method.

3x + 5 = x - 10

Solve for x by isolating the variable.

Subtract 5 from both sides:

3x + 5 - 5 = x - 10 - 5

3x = x - 15

Subtract x from both sides:

3x - x = x - x - 15

2x = -15

Divide both sides by 2:

2x /2 = -15 / 2

x = -15/2.

Answer:

move the variables 3x-x+5=-10 and collect like terms 3x-5=-10-5 and divide both sides 2x=-15

Answer: 8

Step-by-step explanation:

First we must set up the equation.

Jake adds 5 to the number then he multiplies it by 2.

2(x+5)

This is equal to the same number times 5 minus 14.

2(x+5)=5x-14

Distribute.

2x+10=5x-14

Add 14 to both sides.

2x+24=5x

Subtract 2x from both sides.

24=3x.

Divide both sides by 3.

8=x

Answer:

Jake thinks of the number 8.

Hope this helps!

Step-by-step explanation:

Turn the paragraph-given information into an equation:

Adds 5 = x + 5 and then multiplies the result by 2 = ( x + 5 ) * 2

5 times the number = x * 5 then take away 14 = ( x * 5 ) - 14

The same as means :

2 * ( x + 5 ) = ( x * 5 ) - 14

2x + 10 = ( 5x ) - 14

2x + 10 = 5x - 14

2x ( - 2x ) + 10 ( + 14 ) = 5x ( - 2x ) - 14 ( + 14 )

24 = 3x

8 = x

x = 8

If you plug 8 into the two equations, you will find both equations equal 26.

The area of the composite figure is approximately 2447.43 square millimeters to the nearest hundredth.

To find the area of the composite figure, we need to divide it into simpler shapes and then find their areas separately. The composite figure is made up of a rectangle and two semicircles.

First, let's find the area of the rectangle. The length of the rectangle is 55 mm and the width is 32.5 mm, so the area of the rectangle is:

\($$A_{rect} = length \times width = 55 \text{ mm} \times 32.5 \text{ mm} = 1787.5 \text{ mm}^2$$\)

Next, let's find the area of each semicircle. The diameter of each semicircle is equal to the width of the rectangle, which is 32.5 mm. Therefore, the radius of each semicircle is:

\($$r =\) \(\frac{32.5 \text{ mm}}{2} = 16.25 \text{ mm}$$\)

The formula for the area of a semicircle is:

\($$A_{semicircle} = \frac{1}{2} \pi r^2$$\)

So, the area of each semicircle is:

\($$A_{semicircle} = \frac{1}{2} \pi (16.25 \text{ mm})^2 \approx 329.97 \text{ mm}^2$$\)

To find the total area of the composite figure, we add the area of the rectangle to the area of the two semicircles.

\($$A_{total} = A_{rect} + 2 \times A_{semicircle} \approx 2447.43 \text{ mm}^2$$\)

Therefore, the area of the composite figure is approximately 2447.43 square millimeters to the nearest hundredth.

To change this to standard form you have to multiply 3.4 by 10 to the 8th power. You would be multiplying 3.4 by 10 eight times. It's a positive 8 so you move the decimal point 8 times to the right. If it were a negative then you'd move the decimal to the left.

To find the p-value for each coefficient, we would need to conduct a hypothesis test for each predictor variable.

The null hypothesis for each test would be that the coefficient for the predictor variable is equal to 0, and the alternative hypothesis would be that it is not equal to 0. We would then calculate the t-statistic for each predictor variable, and use the t-distribution with 319 degrees of freedom to find the corresponding p-value.

If our α level is .01, we would reject the null hypothesis and conclude that a predictor variable is a significant predictor if its p-value is less than .01.

Conversely, if a predictor variable's p-value is greater than .01, we would fail to reject the null hypothesis and conclude that it is not a significant predictor.

Without any specific information about the predictor variables or the model, I cannot say which predictor variables are not significant predictors.
