3x + y = 3x + y = 2

Solve the system of equations.

A) x = 1/2, y = 3

B) x = 3, y = 1/2

C) x = 1/2, y = 3/2

D) x = 3/2, y = 1/2

Answers

If you would like to solve the system of equations, you can do this using the following steps:

3x + y = 3
x + y = 2 ... y = 2 - x
_________________
3x + y = 3
3x + 2 - x = 3
2x = 3 - 2
2x = 1
x = 1/2

y = 2 - x = 2 - 1/2 = 1 1/2 = 3/2

(x, y) = (1/2, 1 1/2) = (1/2, 3/2)

The correct result would be C) x = 1/2, y = 3/2.

Martha Owens is paid $14.50per hour for a regular forty-hour work
week. Her overtime pay is one-and-one-
half times her regular hourly rate. This

How many hours of overtime did
Martha work this pas week?

Answers

Martha worked approximately 8 hours of overtime during the past week.

Martha's regular hourly rate is $14.50, and she works a regular forty-hour work week. Her overtime pay is one-and-one-half times her regular hourly rate.

Let's break down Martha's earnings for the week:

Regular Earnings (for 40 hours): Regular Hourly Rate × Hours Worked

Regular Earnings = $14.50 × 40 = $580

Total Earnings (including overtime): $754

Overtime Earnings = Total Earnings - Regular Earnings

Overtime Earnings = $754 - $580 = $174

Since Martha's overtime pay is one-and-one-half times her regular hourly rate, we can set up an equation:

Overtime Earnings = Overtime Hourly Rate × Hours of Overtime Worked

Solving for Hours of Overtime Worked:

Hours of Overtime Worked = Overtime Earnings / Overtime Hourly Rate

Overtime Hourly Rate = 1.5 × Regular Hourly Rate

Overtime Hourly Rate = 1.5 × $14.50 = $21.75

Now, plug in the values:

Hours of Overtime Worked = $174 / $21.75 ≈ 8

Martha worked approximately 8 hours of overtime during the past week.

Answers

d1,..,d9 = 0,0,2,2,2,3,4,6,8 //there are 9 values, in ascending order
Q2 (median) = d5 = 2 //value in the middle
Q1 = (d2+d3) / 2 = (0+2)/2 = 1
(Q1 is middle value of d1,d2,d3,d4, but there is no middle element among four elements, that is why arithmetic mean is taken)
Q3 = (d7+d8) / 2 = (4+6)/2 = 5
interquantlie range = IQR = Q3 - Q1 = 5 -1 = 4
answer: 4

Answer:

Option C.

Step-by-step explanation:

The given data set is

0, 2, 4, 0, 2, 3, 2, 8, 6

Arrange the data in ascending order.

0, 0, 2, 2, 2, 3, 4, 6, 8

Divide the data set in 4 equal parts.

(0, 0), (2, 2), 2,( 3, 4), (6, 8)

Now, we get

$Q_1=(0+2)/(2)=1$
