Which of the following equations represents a linear function?

x = 3
y equals one half times x minus 5
y equals three fourths times x squared
3x − 6 = 4

Answer:

200 x 7 = 1,400 x = 7 because there are 7 days in a week

Step-by-step explanation:

The table that shows a proportional relationship is Table A.

A proportional relationship is a type of relationship between two variables in which the ratio of their values remains constant. In other words, as one variable increases or decreases, the other variable also increases or decreases in proportion to it.

In table A, we see that :

= 150 / 3

= 50

= 200 / 4

= 50

= 250 / 5

= 50

Every single value of y, gives the same value of x so this means that the table shows a proportional relationship.

11)  (A) a t-interval for a difference between means for independent samples.

12) the appropriate t-statistic is (C) 1.98.

13) option (c)

The central limit theorem is a principle in probability theory that states that the distribution of sample means will eventually approximate a normal distribution as the sample size becomes larger.

11) The type of study being conducted by Ron is a completely randomized design, where he randomly assigns the two types of golf balls (new and current) to two separate groups and then compares the mean driving distances between the two groups.

The appropriate t-interval for inference is (A) a t-interval for a difference between means for independent samples.

12) To test the hypothesis of whether there is a significant difference in mean driving distance between the new golf balls and the old golf balls, we need to calculate the appropriate t-statistic.

The formula for the t-statistic for a difference between means for independent samples is:

[tex]t = (x_1 - x_2) / [s1^2/n1 + s_2^2/n_2]^{0.5}[/tex]

where x1 and x2 are the sample means, s1 and s2 are the sample standard deviations, and n1 and n2 are the sample sizes for the two groups.

Using the given data, we have:

x1 = 203.5 yards, x2 = 197.4 yards

s1 = 5.6 yards, s2 = 10.3 yards

n1 = n2 = 30

Substituting these values into the formula, we get:

[tex]t = (203.5 - 197.4) / [(5.6)^2/30 + 10.3^2/30]^{0.5} = 1.98[/tex]

Therefore, the appropriate t-statistic is (C) 1.98.

13) The correct statement about the study being conducted by Ron is (C) The central limit theorem tells us that the sampling distribution of driving distance for each of the individual samples of balls will be approximately normal.

Hence, The answers to the question:

Answer: c

Step-by-step explanation:

Answer: Since Connor gets 69% of the money, Maria gets the remaining 31%:

100% - 69% = 31%

Let's first find out how much money Maria makes:

Maria's share = 31% of $595.54

Maria's share = 0.31 x $595.54

Maria's share = $184.61

Now, to find out how much Connor makes, we can subtract Maria's share from the total:

Connor's share = Total - Maria's share

Connor's share = $595.54 - $184.61

Connor's share = $410.93

Therefore, Connor makes about $410.93 (rounded to the nearest dollar).

Step-by-step explanation:

Since the denominator of the expression (1 + 0.1t) cannot be zero, the domain of the model is between t = 0 and t = -10.

In order to identify the values of the independent variable x and acquire the domain, we simply solve the equation y = f(x). Simply put, x=g(y) will calculate the function's range after we identify g's domain (y).

(b) We must assess the model at t = 0 in order to determine the starting number of elk in the herd:

P = (10 + 3.3t)/(1 + 0.1t)

P = (10 + 3.3(0))/(1 + 0.1(0))

P = 10/1

P = 10

(c) We can easily enter the relevant values of t into the model to determine the populations of elk after 25, 59, and 113 years, then round the results to the nearest integer.

When t = 25:

P = (10 + 3.3t)/(1 + 0.1t)

P = (10 + 3.3(25))/(1 + 0.1(25))

P ≈ 47

When t = 59:

P = (10 + 3.3t)/(1 + 0.1t)

P = (10 + 3.3(59))/(1 + 0.1(59))

P ≈ 189

When t = 113:

P = (10 + 3.3t)/(1 + 0.1t)

P = (10 + 3.3(113))/(1 + 0.1(113))

P ≈ 458

(d) We can use the expression's limit as t approaches infinity to determine the expected population limit:

lim P as t → ∞ = lim (10 + 3.3t)/(1 + 0.1t) as t → ∞

Using L'Hopital's rule, we can find that the limit is equal to:

lim P as t → ∞ = lim 3.3/0.1 as t → ∞

lim P as t → ∞ = 33

The farmer's market originally had 400 peaches on hand.

What is an equation?

An equation is a mathematical statement that shows that two expressions are equal. It typically consists of variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, exponents, and radicals.

Let's use x to represent the original number of peaches the farmer's market had on hand.

We know that the farmer's market sold 35% of its produce, which means it sold 0.35x peaches. The remaining number of peaches can be calculated by subtracting the number of peaches sold from the original number of peaches:

remaining peaches = x - 0.35x

We also know that there are 260 peaches remaining, so we can set up an equation:

260 = x - 0.35x

Simplifying this equation, we can combine like terms:

260 = 0.65x

To solve for x, we need to isolate the variable by dividing both sides by 0.65:

x = 260 / 0.65

x = 400

Therefore, the farmer's market originally had 400 peaches on hand.

To explain how we used equivalent ratios, we used the fact that the farmer's market sold 35% of its produce. This can be represented as a ratio of 35/100 or 0.35. We then used this ratio to find the number of peaches sold, which is 0.35x. We also used the fact that the remaining peaches are the original peaches minus the peaches sold, or x - 0.35x. Finally, we set up an equation using the remaining peaches and solved for x to find the original number of peaches.

Hence, the farmer's market originally had 400 peaches on hand.

The equations that have the same value of x as the given equation are:

18x - 9 = 72

3(6x - 3) = 72

x = 4.5

The correct options are the third, fourth, and fifth options

From the question, we are to determine the equations that have the same value of x as the given equation

To solve the given equation, we can begin by simplifying it:

3/5 (30 x - 15) = 72

Multiplying both sides by 5/3, we get:

30 x - 15 = 120

Adding 15 to both sides, we get:

30 x = 135

Dividing both sides by 30, we get:

x = 4.5

Now, to check which equations have the same value of x as the above result, we can substitute x = 4.5 in each option and see which ones result in a true statement.

Substituting x = 4.5, we get:

18(4.5) - 15 = 72

81 - 15 = 72

This is not a true statement, so this option is not correct.

Substituting x = 4.5, we get:

50(4.5) - 25 = 72

225 - 25 = 72

This is not a true statement, so this option is not correct.

Substituting x = 4.5, we get:

18(4.5) - 9 = 72

81 - 9 = 72

This is a true statement, so this option is correct.

Substituting x = 4.5, we get:

3(6(4.5) - 3) = 72

3(24) = 72

This is a true statement, so this option is correct.

4.5 = 4.5

Step-by-step explanation:

To use elimination method, we need to eliminate one of the variables (x or y) by adding or subtracting the two equations. To do this, the coefficients of one of the variables in the two equations should be the same or opposite.

Looking at the two equations:

Equation #1: 2x + 18y = -9

Equation #2: 4x + 18y = -27

We can see that the coefficients of y are already the same in both equations. So, we can eliminate y by subtracting Equation #1 from Equation #2.

However, to do this we need to make sure that the coefficients of x in the two equations are opposites, i.e., one is positive and one is negative.

Therefore, the first step we could take to solve this system using elimination is to multiply Equation #1 by -2 to get:

-4x - 36y = 18

Now the coefficients of x in the two equations are opposites, so we can subtract Equation #1 from Equation #2 to eliminate y and solve for x.

So, the correct answer is:

Multiply equation #1 by -2.

The correct answer is (C) OL'(-1, 2) - This point is on the reflected line y=-2, but its y-coordinate is not consistent with the reflection of L. The correct y-coordinate is -4.

What is line?

A one-dimensional geometric figure that consists of infinitely many points arranged in a straight path or direction.

In this case, we are reflecting across the line y = -2, which is two units below the x-axis. Therefore, the y-coordinate of each point in the preimage will be changed by 2 units after reflection.

The coordinates of L are (-1, -6), and after reflecting across y = -2, the y-coordinate will become

-6 + 2 = -4

Therefore, the image of L, L', will have coordinates (-1, -4).

Looking at the given options:

A. L'(-3, 6) - This point is not on the reflected line y=-2, so it cannot be the reflection of L.

B. OL'(-1,6) - This point is above the reflected line y=-2, so it cannot be the reflection of L.

C. OL'(-1, 2) - This point is on the reflected line y=-2, but its y-coordinate is not consistent with the reflection of L. The correct y-coordinate is -4.

D. OL(1, 2) - This point is not on the reflected line y=-2, so it cannot be the reflection of L.

Hence, a 93% confidence range for the actual proportional difference between the two populations equation (represented by the two samples) is between -0.086 and 0.142.

A mathematical equation connects two statements with the equals sign (=), which stands for equivalence. The equivalence of two mathematical propositions is established by a mathematical assertion that is utilized in algebraic equations. For instance, the equal sign separates the numbers 3x + 5 and 14 in equation 3x + 5 = 14. Use a mathematical formula to understand the relationship between the two sentences written on opposite sides of a letter. Usually, the program's particular logo matches it. A good example is 2x - 4 = 2.

For the initial example:

Sample proportion: 0.649 (p1 = 24/37)

Standard deviation SE1 is equal to

[tex]\sqrt{(p^1*(1-p^1))} /n1=\sqrt{(0.649*(1-0.649))/37)0.087}[/tex]

Regarding the second example:

P2 = 54/87 0.621 is the sample proportion.

The standard deviation SE2 is equal to

[tex]\sqrt{(p^2*(1-p^2))} /n2=\sqrt{(0.621*(1-0.621))/87)0.72}[/tex]

The crucial value for a 93% confidence interval has to be calculated next. We may use the conventional normal distribution and large sample size to obtain the z-value that represents the center 93% of the distribution:

[tex]1.812z=invNorm(\frac{1+0.93}{2} )[/tex]

We can finally determine the confidence interval:

CI is equal to (p1-p2) z*sqrt(SE12 + SE22)

CI is calculated as (0.649 - 0.621) 1.812*sqrt(0.0872 + 0.0722)

CI = 0.028 ± 0.114

CI = (−0.086, 0.142)

The real proportional difference between the two populations (represented by the two samples) thus lies between -0.086 and 0.142, with a 93% confidence interval.

Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.

It displays the similarity of the connections between the phrases on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are examples of the parts of an equation. When creating an equation, the "=" symbol and terms on both sides are necessary.

Given data ,

Let the time at which Neo reaches the work destination be A

Now , the time at which Neo leaves home = 6 : 45 AM

And , the distance between Neo and work = 45 miles
