Answer:

The medal received by an Olympic gymnast has a nominal level of measurement.

Step-by-step explanation:

The variable, X can be described as the type of medal received by an Olympic gymnast.

The values that X can take are: gold, silver and bronze.

The variable X is a qualitative variable, since it describes the different categories of winning a medal.

There are two types of qualitative variable level of measurement:

In case of nominal level of measurement, words, letters, and alpha-numeric symbols are used to denote the category.  For instance, the data about individuals belonging to three different gender categories, the data about individual’s different eye color.

Thus, the medal received by an Olympic gymnast has a nominal level of measurement.

∑                                                                 0.65                      0.6619  

1. The degrees of freedom = n-1= 10-1= 9

2. The significance level is 0.05

3.The test statistic is

t= d`/sd/√n

4. The critical region is ║t║≥ t (0.025,9) = 2.262

The null and alternate hypotheses is

H0 : ud= 0 against Ha: ud≠ 0 (two tailed test)

5. Calculations

d`= ∑di/n= 0.65/10= 0.065

Sd²= ∑(di-d`)²/n-1 = 1/n-1 [∑di²- (∑di)²n]

Sd²= 1/9[0.6619-(0.65)²/10] = [0.6619-0.4225/9]= 0.0266

Sd= 0.163

Therefore

t= d`/ sd/√n

t= 0.065/ 0.163/√10

t= 0.3987/3.1622=0.1261

6. Conclusion

Since the calculated value of t does not fall in the critical region so we accept H0 that there is no price difference between the two stores.

Now the P- value:

The P-value is the rejection region. In this test it is on both sides and would add up to be (2.262 + 2.262)/100= 4.542/100

The P-value  is 0.04542 which is less than 0.05

Step-by-step explanation:

The limit of [f(x) - f(2)]/[x - 2] as x approaches 2 is 20

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

f(x) = 5(x2 – 1)

Rewrite as

f(x) = 5(x² – 1)

The limit is given as

[f(x) - f(2)]/[x - 2]

Calculate f(2)

So, we have

f(2) = 5(2² – 1)

Evaluate

f(2) = 15

Substitute f(2) = 15 in [f(x) - f(2)]/[x - 2]

So, we have

[f(x) - f(2)]/[x - 2] = [5(x² – 1) - 15]/[x - 2]

Open the brackets

[f(x) - f(2)]/[x - 2] = [5x² – 5 - 15]/[x - 2]

Evaluate the like terms

[f(x) - f(2)]/[x - 2] = [5x² – 20]/[x - 2]

Factorize

[f(x) - f(2)]/[x - 2] = [5(x² – 4)]/[x - 2]

Express as difference of two squares

[f(x) - f(2)]/[x - 2] = [5(x – 2)(x + 2)]/[x - 2]

Divide

[f(x) - f(2)]/[x - 2] = 5(x + 2)

Limit x to 2

[f(x) - f(2)]/[x - 2] = 5(2 + 2)

Evaluate

[f(x) - f(2)]/[x - 2] = 20

Hence, the limit is 20

Using the probability table, it is found that:

a) There is a 0.25 = 25% probability that this couple spends 45 dollars or more.

b) The expected amount the couple actually has to pay is $36.85.

From the table, the probabilities of each total cost are:

\(P(X = 30) = P(X = 15|Y = 15) = 0.2\)

\(P(X = 35) = P(X = 15|Y = 20) + P(X = 20|Y = 15) = 0.15 + 0.15 = 0.3\)

\(P(X = 40) = P(X = 15|Y = 25) + P(X = 20|Y = 20) + P(X = 25|Y = 15) = 0.05 + 0.15 + 0.05 = 0.25\)

\(P(X = 45) = P(X = 20|Y = 25) + P(X = 25|Y = 20) = 0.1 + 0.1 = 0.2\)

\(P(X = 50) = P(X = 25|Y = 25) = 0.05\)

Item a:

This probability is:

\(P(X \geq 45) = P(X = 45) + P(X = 50) = 0.2 + 0.05 = 0.25\)

There is a 0.25 = 25% probability that this couple spends 45 dollars or more.

Item b:

The expected value is the sum of each outcome multiplied by it's respective probability.

Hence:

\(E(X) = 0.2(30) + 0.3(35) + 0.25(40) + 0.9[0.2(45) + 0.05(50)] = 36.85\)

The expected amount the couple actually has to pay is $36.85.

x = 12

Step-by-step explanation:

The two given angles create a straight line (Definition of Straight Line). This means that:

\((10x - 20) + (6x + 8) = 180\)

First, combine like terms. Like terms are terms that share the same amount of the same variables:

\((10x + 6x) + (8 - 20) = 180\\(16x) + (-12) = 180\\16x - 12 = 180\\\)

Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations and stands for:

First, add 12 to both sides of the equation:

\(16x - 12 = 180\\16x - 12 (+12) = 180 (+12)\\16x = 180 + 12\\16x = 192\)

Next, divide 16 from both sides of the equation:

\(\frac{16x}{16} = \frac{192}{16} \\x = \frac{192}{16}\\ x = 12\)

Answer:

3x^2+6x

Step-by-step explanation:

3x(x+2)

First distribute the 3x

You end up with

(3x^2+6x)

and that is the answer.

Answer:

We can start by using the second equation to eliminate x:

2x + 5y - 2z = 3

2x = -5y + 2z + 3

x = (-5/2)y + z + 3/2

Now we can substitute this expression for x into the first and third equations:

x + y + z = 4

(-5/2)y + z + 3/2 + y + z = 4

(-5/2)y + 2z = 5/2

x + 7y - 7z = 5

(-5/2)y + z + 3/2 + 7y - 7z = 5

(9/2)y - 6z = 7/2

Now we have a system of two equations with two variables, (-5/2)y + 2z = 5/2 and (9/2)y - 6z = 7/2. We can use any method to solve for y and z, such as substitution or elimination. However, we will find that the system is inconsistent, meaning there is no solution that satisfies both equations.

Multiplying the first equation by 9 and the second equation by 5 and adding them, we get:

(-45/2)y + 18z = 45/2

(45/2)y - 30z = 35/2

Adding these two equations, we get:

-12z = 40/2

-12z = 20

z = -5/3

Substituting z = -5/3 into (-5/2)y + 2z = 5/2, we get:

(-5/2)y + 2(-5/3) = 5/2

(-5/2)y - 10/3 = 5/2

(-5/2)y = 25/6

y = -5/12

Substituting y = -5/12 and z = -5/3 into any of the original equations, we get:

x + y + z = 4

x - 5/12 - 5/3 = 4

x = 29/12

Therefore, the solution is (x, y, z) = (29/12, -5/12, -5/3). However, if we substitute these values into any of the original equations, we will find that it does not satisfy the equation. For example:

2x + 5y - 2z = 3

2(29/12) + 5(-5/12) - 2(-5/3) = 3

29/6 - 5/2 + 5/3 ≠ 3

Since there is no solution that satisfies all three equations, the system is inconsistent.

Step-by-step explanation:

Answer:

See below for proof.

Step-by-step explanation:

A system of equations is not consistent when there is no solution or no set of values that satisfies all the equations simultaneously. In other words, the equations are contradictory or incompatible with each other.

Given system of equations:

\(\begin{cases}x+y+z = 4\\2x+5y-2z =3\\x+7y-7z =5\end{cases}\)

Rearrange the first equation to isolate x:

\(x=4-y-z\)

Substitute this into the second equation to eliminate the term in x:

\(\begin{aligned}2x+5y-2z&=3\\2(4-y-z)+5y-2z&=3\\8-2y-2z+5y-2z&=3\\-2y-2z+5y-2z&=-5\\5y-2y-2z-2z&=-5\\3y-4z&=-5\end{aligned}\)

Subtract the first equation from the third equation to eliminate x:

\(\begin{array}{cccrcrcl}&x&+&7y&-&7z&=&5\\\vphantom{\dfrac12}-&(x&+&y&+&z&=&4)\\\cline{2-8}\vphantom{\dfrac12}&&&6y&-&8z&=&1\end{aligned}\)

Now we have two equations in terms of the variables y and z:

\(\begin{cases}3y-4z=-5\\6y-8z=1\end{cases}\)

Multiply the first equation by 2 so that the coefficients of the variables of both equations are the same:

\(\begin{cases}6y-8z=-10\\6y-8z=1\end{cases}\)

Comparing the two equations, we can see that the coefficients of the y and z variables are the same, but the numbers they equate to is different. This means that there is no way to add or subtract the equations to eliminate one of the variables.

For example, if we subtract the second equation from the first equation we get:

\(\begin{array}{crcrcl}&6y&-&8z&=&-10\\\vphantom{\dfrac12}-&(6y&-&8z&=&\:\:\;\;\:1)\\\cline{2-6}\vphantom{\dfrac12}&&&0&=&-11\end{aligned}\)

Zero does not equal negative 11.

Since we cannot eliminate the variable y or z, we cannot find a unique solution that satisfies all three equations simultaneously. Therefore, the system of equations is inconsistent.

Cube B

Step-by-step explanation:

a = \(\sqrt[3]{125}\)

a = 5

6in x 6in = 36\(in^{2}\)

5 < 6 so A < B

The side length of Cube A ≈ 5 inches

The side length of Cube B = 6 inches

Cube B has a greater side length than Cube A.

We have,

To compare the side lengths of Cube A and Cube B, we need to find the side length of each cube.

For Cube A:

The volume of Cube A = side length³

125 = side length³

To find the side length of Cube A, we take the cube root of 125:

side length of Cube A = ∛125 ≈ 5 inches

For Cube B:

The area of one face of Cube B = side length²

36 = side length²

To find the side length of Cube B, we take the square root of 36:

side length of Cube B = √36 = 6 inches

Now, we can compare the side lengths of both cubes:

The side length of Cube A ≈ 5 inches

The side length of Cube B = 6 inches

Since 6 inches is greater than 5 inches, Cube B has a greater side length than Cube A.

Thus,

Cube B has a greater side length than Cube A.

3. The volume of the Pringle Chips container is approximately 2034.72 cubic inches.

4. The cake takes up approximately 7317 cubic inches of space.

5. The volume of foam in the model of the volcano is approximately 7234.08 cubic centimeters.

1. The units for Volume are always cubed.

2. Volume is the amount of space an object takes up. True.

3. To calculate the volume of the Pringle Chips container, we need to find the volume of a cylinder. The formula for the volume of a cylinder is V = πr^2h, where π is a constant (approximately 3.14), r is the radius, and h is the height. Given that the diameter is 9 inches, the radius would be half of that, which is 4.5 inches. Substituting the values into the formula, we have:

V = 3.14 * (4.5)^2 * 32

V = 3.14 * 20.25 * 32

V ≈ 2034.72 cubic inches

4. To find the volume of the 3-tier cake, we need to find the volume of each tier separately and then add them together. Since all the tiers are cylinders, we can use the formula V = πr^2h.

Tier 1:

V1 = 3.14 * (12)^2 * 10 = 4521.6 cubic inches

Tier 2:

V2 = 3.14 * (8)^2 * 10 = 2010.4 cubic inches

Tier 3:

V3 = 3.14 * (5)^2 * 10 = 785 cubic inches

Total volume:

Total V = V1 + V2 + V3

Total V = 4521.6 + 2010.4 + 785

Total V ≈ 7317 cubic inches

5. To find the volume of the Styrofoam model of the volcano, we can use the formula for the volume of a cone, V = (1/3)πr^2h. Given that the diameter is 48 centimeters, the radius would be half of that, which is 24 centimeters. Substituting the values into the formula, we have:

V = (1/3) * 3.14 * (24)^2 * 12

V = (1/3) * 3.14 * 576 * 12

V ≈ 7234.08 cubic centimeters

The limit of the difference quotients for f(x) = x^2 + 2x + 1 as x approaches -1 is indeterminate.

To find the limit of the difference quotients for the function f(x) = x^2 + 2x + 1 as x approaches -1, we need to evaluate the following expression:

lim(x→-1) [f(x) - f(-1)] / (x - (-1))

First, let's substitute the values into the expression:

lim(x→-1) \([(x^2 + 2x + 1) - (-1^2 + 2(-1) + 1)] / (x + 1)\)

Simplifying further:

lim(x→-1) \([(x^2 + 2x + 1) - (1 - 2 + 1)] / (x + 1)\)

lim(x→-1)\([x^2 + 2x + 1 - 0] / (x + 1)\)

lim(x→-1) \((x^2 + 2x + 1) / (x + 1)\)

Now, we can directly substitute x = -1 into the expression:

\((-1^2 + 2(-1) + 1) / (-1 + 1)\)

(1 - 2 + 1) / (0)

0 / 0

We have obtained an indeterminate form of 0/0. This indicates that we need to further simplify the expression or use other techniques, such as L'Hôpital's rule, to evaluate the limit. However, without additional information or simplification, we cannot determine the precise value of the limit at x = -1.
