Step-by-step explanation:

We start by trying out option A

2(1) + 3(3) = 9

1 + 5(3) = 15

9 and 15 are not equal to one another.

This means it has to be the other option, B.

Answer:

19.5 is the median

Step-by-step explanation:

count the amount of numbers presented and we have 6, the next decision differs on whether or not the amount is an even amount or odd, in this case it is an even number.  So divide your amount by 2 and we have 3.  Then count your first 3 numbers and on the third number you will need to find the average between the third and fourth number, so that would mean finding the number that is in the middle of these two numbers and we have 19.5.

The surface area of the portion S of the cone z^2 = x^2 + y^2 where z>/ 0 contained within the cylinder y^2 + z^2 < 1 is 8π.

The cone is defined by the equation z^2 = x^2 + y^2.

The cylinder is defined by the equation y^2 + z^2 < 1.

The intersection of the cone and the cylinder is a surface that is part of a cone and part of a cylinder.

The surface area of the cone is given by the formula A = πr^2h, where r is the radius of the base and h is the height of the cone.

The radius of the base of the cone is equal to 1, and the height of the cone is equal to √2. Therefore, the surface area of the cone is π(1)^2(√2) = √2π.

The surface area of the cylinder is given by the formula A = 2πrh, where r is the radius of the base and h is the height of the cylinder.

The radius of the base of the cylinder is equal to 1, and the height of the cylinder is equal to 1. Therefore, the surface area of the cylinder is 2π(1)(1) = 2π.

The surface area of the intersection of the cone and the cylinder is equal to the surface area of the cone minus the surface area of the cylinder. Therefore, the surface area of the intersection is √2π - 2π = 8π.

Step-by-step explanation:

The following is true about the study: e. It has one factor (medication) blocked by age.

In statistics, when a factor (independent variable) is blocked by another factor, it means that the effect of the first factor is controlled or eliminated by the second factor.

In this case, the factor that is blocked is the medication, which means that the effect of medication on the outcome variable is controlled by age.

Blocking a factor is often done in experimental design to remove the effects of extraneous variables or to control the influence of certain factors on the outcome variable.

In this case, age is considered a blocking variable because it is not of interest in the study, but it may have an effect on the outcome variable. By blocking the effect of medication by age, the study can better isolate the effect of medication on the outcome variable.

In summary, the statement e. "It has one factor (medication) blocked by age" is correct which means that the study controlled for the effect of age on the outcome variable by blocking the effect of medication by age.

Answer:

The initial value is $5.00

Step-by-step explanation:

The question required us to find the y-intercept or c in the equation of the straight line.

We are given 4 different points on the graph and we are also told the hourly fee. As we know that the graph has total hours on x axis and total cost on y axis, we can calculate the gradient or slope of the graph.

m = (23 - 18.5) / (4 - 3)

m = 4.5

Taking point (3,18.5) for calculating c or y intercept from the equation of straight line that is,

y = m (x) + c

18.5 = 4.5 (3) + c

18.5 = 13.5 + c

18.5 - 13.5 = c

c = 5

So the admission fee is $5.

Answer:

a) 2 cm

b) 34 cm

c) 44 cm²

Step-by-step explanation:

a) 9 cm - 4 cm - 3 cm = 2 cm

b) 9 cm + 5 cm + 4 cm + 2 cm + 2 cm + 3 cm + 3 cm + 6 cm = 34 cm

c) 5 cm × 4 cm + 2 cm × 3 cm + 3 cm × 6 cm = 44 cm²

The solution of the quadratic equation is \(x = \dfrac{5\pm\sqrt5}{2}\).

A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

Given that the quadratic equation is x²-5x+5=0. The equation can be solved as below:-

x²-5x+5=0

a = 1 , b = -5 , c = 5

\(x = \dfrac{-b \pm\sqrt{(b^2-4ac}}{2a}\)

\(x=\dfrac{5\pm\sqrt{25 - 4\times1\times5}}{2}\)

\(x = \dfrac{5\pm\sqrt5}{2}\)

The value of x for the quadratic equation will be \(x = \dfrac{5\pm\sqrt5}{2}\).

Since the information about variable 'q' is not provided, it is not possible to determine the remainder when q is divided by 6 based on the given context.

The question states that x is a positive integer such that x ≥ 75, but it does not provide any information about the variable 'q'. Without knowledge of the value or any relationship between 'q' and 'x', we cannot determine the remainder when 'q' is divided by 6.

The remainder will depend on the specific value of 'q' and how it relates to the number 6. Therefore, without further information, it is not possible to determine the remainder when 'q' is divided by 6.

The samples of size n = 2 that can be drawn from this population is 28

From the question, we have the following parameters that can be used in our computation:

Population, N = 8

Sample, n = 2

The samples of size n = 2 that can be drawn from this population is calculated as

Sample = N!/(n! * (N - n)!)

substitute the known values in the above equation, so, we have the following representation

Sample = 8!/(2! * 6!)

Regardless of the distribution of points for individual problems, each scenario consists of 35 problems in total.

To determine the number of problems of each point value on the test, we can analyze each scenario individually:

Scenario: 10 problems worth 5 points and 25 problems worth 2 points

Number of 5-point problems: 10

Number of 2-point problems: 25

Scenario: 15 problems worth 5 points and 20 problems worth 2 points

Number of 5-point problems: 15

Number of 2-point problems: 20

Scenario: 20 problems worth 5 points and 15 problems worth 2 points

Number of 5-point problems: 20

Number of 2-point problems: 15

Scenario: 25 problems worth 5 points and 10 problems worth 2 points

Number of 5-point problems: 25

Number of 2-point problems: 10

In each scenario, the total number of problems is the sum of the 5-point problems and the 2-point problems.

Now let's calculate the total number of problems for each scenario:

Scenario:

Total number of problems = 10 + 25 = 35

Scenario:

Total number of problems = 15 + 20 = 35

Scenario:

Total number of problems = 20 + 15 = 35

Scenario:

Total number of problems = 25 + 10 = 35

In all scenarios, there are a total of 35 problems on the test.

To summarize, the point values assigned to each problem may vary, but the overall number of problems remains constant.

It's worth noting that this analysis assumes that there are no other point values assigned to the problems on the test. If there are additional point values or if there is more information provided, the calculations may change accordingly.

The term "repeated measures" refers to one sample getting data taken from two times. Therefore, the correct option is option 3.

Repeated measures refer to a type of experiment design in which the same subjects are used in all treatments. In this design, each subject is exposed to more than one treatment. Repeated measures is also referred to as within-subjects or intra-subjects design.

The repeated measures design is a powerful approach since it provides for higher accuracy by using fewer participants than would be needed in a between-subjects design. It also has the advantage of being more statistically efficient since it uses each subject as his/her control.

Therefore, in a repeated measures design, one sample is used three times, and the sample gets data taken from two times. This means that the same participants are measured on the same variable multiple times, allowing researchers to analyze the effects of an intervention or change over time. Hence, option 3 is the correct answer.
