A store manager wishes to investigate whether there is a relationship between the type of promotion offered and the number of customers who spend more than $30 on a purchase. Data will be gathered and placed into the two-way table below. Customer Spending by Promotion Run Customers Spending More than $30 Customers Spending $30 or Less $10 off $50 15% off $5 off $25 Buy-1-Get-1 Half Off Which statement best describes how the manager can check if there is an association between the two variables? The manager must check relative frequencies by row because there are more than two different promotions. The manager must check relative frequencies by column because there are more than two different promotions. The manager cannot use relative frequencies to look for an association because there are more than two different promotions. The manager should check both relative frequencies by row and by column to look for an association.

Answer:

exact form:

\(x=\frac{11}{5}\)

Decimal:

\(x=2.2\)

Mixed Number Form:

\(x=2\frac{1}{5}\)

Step-by-step explanation:

simplify \(2(x + 6) + 4\)

\(2(x + 6) + 4 = 12x - 6\)

Move all terms containing  x  to the left side of the equation.

\(-10x+1=-6\)

Move all terms not containing  x  to the right side of the equation.

\(-10x=-22\)

Divide each term by  − 10  and simplify.

\(x=\frac{11}{5}\)

the result can be shown in multiple forms

Exact Form: \(x=\frac{11}{5}\)

Decimal Form: \(x=2.2\)

and Mixed Number Form: \(x=2\frac{1}{5}\)

Answer:

1 adult ticket and 7 student tickets were purchased

Step-by-step explanation:

let a represent number of adult tickets purchased and s the number of student tickets purchased, then

a + s = 8 ( subtract s from both sides )

a = 8 - s → (1) ← based on total tickets purchased

10.5a + 7.25s = 61.25 → (2) ← based on cost of tickets

substitute a = 8 - s into (2)

10.5(8 - s) + 7.25s = 61.25

84 - 10.5s + 7.25s = 61.25

84 - 3.25s = 61.25 ( subtract 84 from both sides )

- 3.25s = - 22.75 ( divide both sides by - 3.25 )

s = 7

substitute s = 7 into (1)

a = 8 - 7 = 1

that is 1 adult ticket and 7 student tickets were purchased

Table one and table four represent a linear function.

A linear function is simply a function that represents a straight line on the coordinate plane.

For a function to be linear, the differences of the y-values must be constant.

For table 1.

Let get the differences of the y-values

-1 - (-2) = 1

0 - (-1) = 1

1 - 0 = 1

2 - 1 = 1

Since the differences of the y-values are all 1 ( constant ), table one is a linear function.

For table 2.

2 - (-3) = 5

0 - 2 = -2

-2 - 0 = -2

3 - (-2) = 5

Since the differences of the y-values are not the same ( constant ), table two is not a linear function.

For table 3.

0 - 2 = -2

-1 - 0 = -1

0 - (-1) = 1

2 - 0 = 2

Since the differences of the y-values are not the same ( constant ), table three is not a linear function.

For table 4.

1 - 3 = -2

-1 - 1 = -2

-3 - (-1) = -2

-5 - (-3) = -2

Since the differences of the y-values are all -2 ( constant ), table four is a linear function.

Answer:

The equation of the line with a slope of 2 and a y-intercept of 4 in the slope-intercept is:

Hence, option 'A' is correct.

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

In our case, we are given

substituting m = 2 and b = 4 in the slope-intercept form of the line equation

y = mx+b

y = 2x + 4

Therefore, the equation of the line with a slope of 2 and a y-intercept of 4 in the slope-intercept is:

Hence, option 'A' is correct.

Answer:

1 can sing but cannot play keyboard.

Step-by-step explanation:

There are six members in the rock band. We need to identify how many person can sing, play guitar and play keyboard. To identify this we will find out number of member for each activity,

Total 6 members

4 can play guitar

3 can pay keyboard

All singers play guitar but one guitarist cannot sing.

There will be 1 singer who cannot play keyboard.

The monthly payment is ​$453.125.

If the initial amount (also called as principal amount) is P, and the interest rate is R% annually, and it is left for T years for that simple interest, then the interest amount earned is given by:

\(I = \dfrac{P \times R \times T}{100}\)

Given;

Amount Financed (P) = $15,000

Annual Percentage Rate (R) = 5%

Number of Payments per Year (N) = 12

Time in Years (T) = 3

Now, monthly payment;

=(p*i*(1+i)^n)/((1+i)^n-1)

=15000(0.05/12)(1+0.05/12)^36/(1+0.05/12)^36-1

= 72.5/0.16

=453.125

Therefore, the monthly payment by 5% interest will be $453.125.

The daily lunch sets cost $6, while the special lunch sets cost $36.

A linear equation with two variables consists of the greatest power of a variable being one.

Now, for the given condition in the question;

Let the price of the daily lunch set is 'x'.

Let the price of the special lunch set is 'y'.

Then, 2 daily lunch sets and 3 special lunch sets costs $120.

2x + 3y = 120     .......(equation 1)

And, 5 daily lunch sets and 2 special lunch sets costs $157.

5x + 2y = 157    ......(equation 2)

Using elimination method to solve equation 1 and 2.

y = 36 (price of each special lunch sets)

x = 6 (price of each daily lunch sets)

Therefore, the price for the daily lunch sets is $6 and price for special lunch sets is $36 in an restaurant.

The number of trucks calculated using system of equations is 30

Let :

Number of trucks = a

Number of cars = b

Charge per car = $4

Charge per truck = $6

We could form a system of equation thus:

From (1)

b = 200 - a

6a + 4(200 - a) = 860

6a + 800 - 4a = 860

2a = 860 - 800

2a = 60

a = 30

Answer:

The statements are not provided, so let's do a complete description of f(x)

In the graph, we can see two asymptotes at x = 1.

This means that the denominator is equal to 0 when x = 1, then we can write:

f(x) = A/(x - 1)

Where we can start thinking that A is a constant.

Now we also can see that when x = 2, f(2) is equal to 1, or:

f(2) = 1.

Then:

f(2) = 1   = A/(2 - 1) = A/1

Then we have  A = 1.

Then our function is:

f(x) = 1/(x - 1)
