Sam works as a waiter in a restaurant. He earns $1,400 per month as a base salary, plus tips averaging 15% of the meals he serve
fgiga [73]

Answer:

Part a) The linear model is y=1,400+0.15x

Part b) The amount earned is y=\$2,300

Step-by-step explanation:

Let

x ----> total meals worth served by Sam in a month

y ----> total earned by Sam in a month

we know that

The total earned by Sam in a month is equal to the base salary plus the  total meals worth served by Sam in a month multiplied by the tips averaging in decimal form

Tips average =15%=15/100=0.15

so

y=1,400+0.15x

This is a linear equation in slope intercept form

y=mx+b

where

m is the slope or the unit rate

b is the y-intercept or initial value

The slope of unit rate is equal to

m=0.15

The y-intercept or b is equal to

b=1,400

For x=6,000

substitute in the linear equation

y=1,400+0.15(6,000)

y=\$2,300

The question is incomplete. Here is the complete question.

A cell phone company is interested in the relationship between the number of texts per minute for their customers (y) and customer age. Based on the data collected, the least-squares regression line is y=3.27+2.14x, where x is the number of years by which age exceeds 12. Which of the following statements best describes the meaning of the slope of the least-squares regression line?

a. For each increase in age of 1 year, the estimated number of texts per minute increases by 3.27.

b. For each increase in age of 1 year, the estimated number of texts per minute increases by 2.14.

c. For each increase of one text per minute, there is an estimated increase in age of 3.27 years.

d. For each increase of one text per minute, there is an estimated increase in age of 2.14 years.

e. The slope has no meaning because the units of measure for x and y are not the same.

Answer: b. For each increase in age of 1 year, the estimated number of texts per minute increases by 2.14.

Step-by-step explanation: The <u>least-squares</u> <u>regression</u> is a method of fitness, i.e., it fits a data set of number into an equation.

In this case, the relationship between number of texts per minute and customer age is given by a line equation:

y=3.27+2.14x

in which, y represents the number of texts per minute and x is the age.

In a line equation, slope is the measure of steepness, i.e., how inclined the line is.

In the least squares regression line, slope is 2.14 and it means, in each additional year, the number of texts increase by a factor of 2.14, which is the correct alternative.

50 POINTS - A Builder intends placing 7 equally spaced homes on a semicircular plot. If the circle has a diameter of 400 feet, w
Ray Of Light [21]

Answer:  89.7 ft

<u>Step-by-step explanation:</u>

Find the arc length (s) of the semi-circle.  Then divide that length by 7.

s = r · θ      where r is the radius and θ is the angle in radians

s = (400 ÷ 2) · π        <em>(radius is diameter divided by 2)</em>

  = 200π

  = 628.3

The length of the arc is 628.3 ft.  Divide that by 7 to find the distance between each home.

628.3 ÷ 7 = 89.7

Rudik [331]

Answer:

The y-intercept is 4

Step-by-step explanation:

You find the y-intercept by finding where x is zero. In the table, when x=0 the y=4. The y-intercept is 4. The graph of the function crosses the x-axis at the point (0,4).
