Answer:

The commission rate is 15%

Step-by-step explanation:

commission = commission rate x sales

where the commission rate is expressed as a decimal.

In this case, the salesperson earned a commission of $345 for selling $2,300 in merchandise. Therefore, we have:

345 = commission rate x 2300

To solve for the commission rate, we can divide both sides by 2300:

commission rate = 345/2300

Simplifying this expression, we get:

commission rate = 0.15

So, the commission rate is 15%

Answer:

growth rate: 4

y-value: 19

equation: y=4x+19

Step-by-step explanation:

Growth Rate:
The growth rate of a linear function is constant. This means that the function will increase or decrease by the same amount for every unit increase in x.
This can be found by dividing the change in y-values by the change in x-values.

For the question:
The change in y-values is 11-7=4,

and the change in x-values is +1.

Therefore, the growth rate is 4.

\(\hrulefill\)

Initial Value: The initial value of a linear function is the value of the function when x is 0.

In this case, the initial value is 19.

This can be found by looking at the y-value of the point where x is 0.

In this case, the y-value is 19.

\(\hrulefill\)Equation: The equation of a linear function is y = mx + b, where m is the slope and b is the y-intercept.

Using the table you provided, we can find the slope by using two points on the line.

Let’s use (-3, 7) and (1, 23).

The slope is (y2-y1)/(x2-x1)=(23-7)(1-(-3)=16/4=4

Now,

Taking 1 point (-3,7) and slope 4.

we can find the equation by using formula:

y-y1=m(x-x1)

y-7=4(x+3)

y=4x+12+7

y=4x+19

Therefore, the equation of the given table is y=4x+19\(\hrulefill\)

Answer:

Growth rate:  4

Initial value:  19

Equation:  y = 4x + 19

Step-by-step explanation:

The slope of a linear function represents its growth rate.

Therefore, the growth rate of a linear function can be found using the slope formula.

Substitute two (x, y) points from the table into the slope formula, and solve for m.  Substituting points (0, 19) and (1, 23):

\(\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{23-19}{1-0}=\dfrac{4}{1}=4\)

Therefore, the growth rate of the linear function is 4.

The initial value of a linear function refers to the y-intercept, which is the value of the y when x = 0.

From inspection of the given table, y = 19 when x = 0.

Therefore, the initial value of the linear function is 19.

To write a linear equation given the growth rate (slope) and initial value (y-intercept), we can use the slope-intercept formula, which is y = mx + b. The slope is represented by the variable m, and the y-intercept is represented by the variable b.

As the growth rate of the given linear function is 4, and the initial value is 19, substitute m = 4 and b = 19 into the slope-intercept formula to create the equation of the linear function represented by the given table:

\(\boxed{y=4x+19}\)

The required answers are a) Team A runs further than Team B. b)  Team A runs 1/6 km less than Team B.

To compare the distance run by the two teams, we need to find the total distance run by Team A:

Total distance run by Team A = Kenny's distance + Kylie's distance

= 7/3 km + 23/6 km (we need to have a common denominator to add the fractions)

= (14/6 + 23/6) km

= 37/6 km

Now we can compare the distances run by the two teams:

a) Team A runs 37/6 km, while Team B runs 19/3 km. To compare these two distances, we need to have a common denominator:

Team A's distance = 37/6 km

Team B's distance = 19/3 km

So, Team A runs further than Team B.

b) To find out how much further Team A runs, we need to subtract Team B's distance from Team A's distance:

Team A's distance - Team B's distance = 37/6 km -  19/3 km

= 37/6 km - (19/3) km

= -1/6 km

So, Team A runs 1/6 km less than Team B. Alternatively, we could say that Team B runs 1/6 km further than Team A.

If 3x – y = 5 and 2x + y = 15  then evaluation of  x^2 + 2y is equal to 72.

What is evaluation ?

Finding the value of an algebraic expression when a given number is used to replace a variable is known as evaluating the expression. When evaluating an expression, we change the variable in the expression to the given number and then use the order of operations to simplify the expression.

3x-y=5 and 2x+y= 15

Add the two equations together to eliminate y

3x-y=5

2x+y= 15

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

5x = 20

Divide by 5

5x/5 = 20/5

x = 4

Step-by-step explanation:

Customers eat 7/8. Tony says it's 14/16

\( \frac{7}{8} = \frac{14}{16} \)

because 7 times 2 is 14 and 8 times 2 is 16, so he got to the correct conclusion

Tony says...

\( \frac{1}{7} + \frac{1}{14} = \frac{14}{16} \)

There's no way to get this answer because neither 7 or 14 goes evenly into 16.

Tony got the correct answer, but his addition is incorrect for that said reason

Answer:

Tony's addition is correct.

Step-by-step explanation:

Tony needs to add 7 two times, since the customers ate 7 slices of out both pizzas. And, 7 + 7 is 14, and you need to also count the total slices of pizza, which is 16. So, the fraction would be 14/16, which can be simplified into 7/8, which is just 14/16 multiplied by 2.

https://brainly.com/question/28276953

Answer:

Step-by-step explanation

1. The total cost of the trip for all 16 families is Rs 2,16,352.
2. To find out how much each family paid, we need to divide the total cost by the number of families: Rs 2,16,352 ÷ 16.
3. When we do the division, we get the result: Rs 13,522.

Now let's check if this result is correct:

1. If each family paid Rs 13,522 for the trip, then the total cost for all 16 families would be: 16 × Rs 13,522 = Rs 2,16,352.
2. This is exactly the same as the total cost given in the problem statement.

So we have shown that each family paid **Rs 13,522** for the trip

Step-by-step explanation:

Answer:

The test value is z = -1.31.

Step-by-step explanation:

The Eagle Ridge Contractors Association claims the average price of a home in their subdivision is $125,150.

This means that the null hypothesis is that the mean is this value, that is:

\(H_0: \mu = 125150\)

The Eagle Ridge Home Owners Association is interested in knowing if the costs of homes for sale in this subdivision are actually lower than claimed.

This means that at the alternate hypotehsis we test that the mean is lower than that value, that is:

\(H_a: \mu < 125150\)

The test statistic is:

\(z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}\)

In which X is the sample mean, \(\mu\) is the value tested at the null hypothesis, \(\sigma\) is the standard deviation and n is the size of the sample.

125150 is tested at the null hypothesis:

This means that \(\mu = 125150\)

Standard deviation of $7,350.

This means that \(\sigma = 7350\)

A sample of 36 homes for sale in this subdivision had an average selling price of $123,550.

This means that \(n = 36, X = 123550\)

Compute the test value.

\(z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}\)

\(z = \frac{123550 - 125150}{\frac{7350}{\sqrt{36}}}\)

\(z = -1.31\)

The test value is z = -1.31.

Sam will receive 142 chocolates.

To find the number of chocolates Sam will get, we need to calculate the sum of squares of the given numbers: 7 + √22 and 7 - √22.

Let's calculate the square of the first number:

(7 + √22)^2 = (7 + √22)(7 + √22)

Using the formula (a + b)(a + b) =\(a^2 + 2ab + b^2\):

= 7^2 + 2(7)(√22) + (√22\()^2\)

= 49 + 14√22 + 22

= 71 + 14√22

Now, let's calculate the square of the second number:

(7 - √22\()^2\) = (7 - √22)(7 - √22)

Using the formula (a - b)(a - b) = \(a^2 - 2ab + b^2\):

= 7^2 - 2(7)(√22) + (√22\()^2\)

= 49 - 14√22 + 22

= 71 - 14√22

Now, we can find the sum of the squares:

(71 + 14√22) + (71 - 14√22)

= 71 + 71 + 14√22 - 14√22

= 142

Therefore, Sam will receive 142 chocolates.

It is not possible to find a combination using addition and multiplication of the given single-digit numbers that totals exactly 100 while keeping the same order.

To combine the single-digit numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9 using only addition and multiplication so that they total 100 while keeping the same order, we can form the following expression:

1 + 2 + 3 + 4 + 5 + 6 + 78 + 9

In this expression, we group the numbers 7 and 8 together to form 78. Then, we add all the other numbers from 1 to 6 and the number 9. Adding them up, we get:

1 + 2 + 3 + 4 + 5 + 6 + 78 + 9 = 108

Unfortunately, the sum obtained from this expression is 108, not 100 as required.

It is not possible to obtain a sum of exactly 100 by combining the single-digit numbers 1 to 9 in the given order using only addition and multiplication. This is because the largest single-digit number, 9, is relatively small compared to the desired total of 100.

Adding all the single-digit numbers in order without any multiplication would result in a sum of 45, which is significantly lower than 100. Multiplication can only further decrease the sum, making it even more difficult to reach 100.
