A Rhombus is labeled ABCD. If the slope of AD is 2/3, what is the slope of BC?

The required approximate sample mean salary is $17750.725.

To approximate the sample mean, we first need to find the midpoint of each salary range and then multiply it by the number of employees in that range to get the total salary for that range. Then we can sum the total salaries and divide by the total number of employees to get the sample mean.

The midpoint of each salary range can be found by taking the average of the lower and upper bounds of the range. For example, the midpoint of the first range (3.001-10,000) is (3.001 + 10,000) / 2 = 5001.5005.

Using this approach, we can construct the following table:

Salary (5) Employees Midpoint Total Salary

3.001-10,000 14 5001.5005 70021.007

10.001-15,000 16 12500.5000 200008.000

15.001-20,000 14 17500.5000 245007.000

20.001-25.000 17 22500.5000 382511.500

25.001-30.000 19 27500.5000 522510.500

To find the sample mean, we add up the total salaries and divide by the total number of employees:

[tex]$\bar{x} = \frac{\sum_{i=1}^n x_i}{n} = \frac{70021.007 + 200008.000 + 245007.000 + 382511.500 + 522510.500}{14 + 16 + 14 + 17 + 19} \approx 17750.725$[/tex]

Therefore, the approximate sample mean salary is $17750.725

Answer:

15: x < 1

16: x ≥ -2

17: x > 0

18: x ≤ 3

19: x equals the number of people in the auditorium

x ≤ 1200

Answer:

y = -3/4x - 2

Step-by-step explanation:

y = -3/4x + b

1 = (-3/4) × -4 + b

1 = 3 + b

-2 = b

b = -2

y = -3/4x -2

Answer:

  B.  No solutions

Step-by-step explanation:

The equations describe lines with the same slope but different y-intercepts. They are parallel, so cannot intersect.

There are no solutions.

Answer:

49.27

Step-by-step explanation:

[tex]\frac{x}{44} = \frac{113}{100}[/tex] - this is what you're going to set up. 113 is 100%+13%, which is what you need to solve the question, since we have 44 set up as our base size (and equal to 100%). Cross multiply so you are left with 100x=4927, then solve for X, and you get our answer of 49.27. Round accordingly.

Given:

A container holds 4 gallons of lemonade.

A large lemonade contains 16 ounces.

To find:

The number of large lemonades that the restaurant can cell before they ran out of lemonade.

Solution:

We know that,

1 gallon = 128 ounces

4 gallon = 512 ounces

So, a container holds 512 ounces of lemonade.

A large lemonade contains 16 ounces. So,

[tex]\text{Number of large lemonades}=\dfrac{\text{Total lemonade in container}}{\text{Lemonade in a large container}}[/tex]

[tex]\text{Number of large lemonades}=\dfrac{512}{16}[/tex]

[tex]\text{Number of large lemonades}=32[/tex]

Therefore, the required number of lemonades is 32.

Complete Question

Every time Luisa bakes a batch of brownies she uses 1/2 cup of chocolate if she has 3/2 cups of chocolate remaining how many batches of brownies can Luisa make

Answer:

3 batches of brownies from 3/2 cups of chocolate left.

Step-by-step explanation:

From the question, we know that:

1/2 cups of chocolate = 1 batch of brownies

3/2 cups of chocolate = x

Cross Multiply

1/2 × x = 3/2

x = 3/2/1/2

x = 3/2 × 2/1

x = 3 batches.

Approximately as a whole number , he can make 3 batches of brownies from 3/2 cups of chocolate left

Answer:

The number is 9.

Step-by-step explanation:

Let x be the number.

[tex]\frac{x}{2}-3=\frac{x}{6}\\\frac{x}{2}-\frac{x}{6}=3\\3x-x=18\\2x=18\\x=9[/tex]

Answer:

6 and 0

Step-by-step explanation:

When we have f(-3) and f(6), that means we plug -3 and 6 in for x to solve for f(x):

f(-3) = (-2/3) * (-3) + 4 = 2 + 4 = 6

f(6) = (-2/3) * 6 + 4 = -4 + 4 = 0

The answers are thus 6 and 0.

Answer:

22

Step-by-step explanation:

hope this helps u. if not, then im sorry.

Answer:

f(6) = 30 hope you get it right

Step-by-step explanation:

f(6) = 4(6) + 6
