Answer:

D. 38.5 square units

Step-by-step explanation:

The area of an obtuse triangle can be figured out in the same way as any other triangle: ¹/₂bh. Substitute b and h for 11 and 7 respectively.

¹/₂(11(7))

1/2 * 77/1

Three shipping companies want to compare the mean numbers of deliveries their drivers complete in a day.

The first two shipping companies provided their data from a sample of drivers in a table.

Company C showed its data in a dot plot.


Answer the questions to compare the mean number of deliveries for the three companies.

1. How many drivers did company C use in its sample?


Write your answer in the space below.















2. What is the MAD for company C's data? Show your work.


Write your answer in the space below.















3. Which company had the greatest mean number of deliveries?


Write your answer in the space below.















4. Compare the means for companies A and B. By how many times the MAD do their means differ? Show your work.


Write your answer in the space below.

Answers

Answer:

Step-by-step explanation:

1. the company C used 10 drivers

2.      6 + 7 + 8 + 9 + 10 + 10 + 10 + 12 + 14 + 14 = 100/10. The Mean = 10  

(6- 10) + (7- 10) + (8- 10) + (9- 10) + (10- 10) + (10- 10) + (10- 10) + (12- 10) + (14- 10)

4 + 3 + 2 + 1 + 0 + 0 + 0 + 2 + 4  = 16/10 = 1 6/10

3. The groups that had the most deliveries where group A and B

4. So if there are 6 deliveries of group A and 14 deliveries from group B i think the MAD would be 4

By reading the dot plot,

Number of drivers used by company C in its sample = 10

Mean absolute deviation for company C's data = 2

Company B has the greatest mean number of deliveries.

The mean deliveries of company B is 4 times MAD of company A.

What is dot plot?

Dot plot is a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis.

Number of units used in the sample of a dot plot can be calculated by simple counting.

What is mean absolute deviation?

The mean absolute deviation (MAD) is the mean distance between each data value and the mean of the data set.

We are given the sum of each point from the mean. It is 20. Mean absolute deviation can be calculated by dividing this sum by number of observations.

Mean absolute deviation of company C  = 20/10 = 2.

Mean A = 6

Mean B = 14

Mean B - Mean A = 8 = 4 * 2 = 4 times MAD (since MAD =2 for both companies).

x^2 + 8x + __ = 0

Answers

Answer:

−x^2 − 8x

Step-by-step explanation:

Lets say y is the missing value

Add -x^2 to both sides.

x^2+8x+y+−x^2=0+−x^2

8x+y=−x^2

Add -8x to both sides.

8x + y + −8x = −x^2 + −8x

y = −x^2 − 8x

So the whole equation would be

x^2 + 8x + −x^2 − 8x = 0

Divide using synthetic division (x^2 +9)÷(x-3) =​

Answers

Answer: x+3+ 18/x-3

Step-by-step explanation:

The complete division problem can be written as:

(x² + 9) / (x-3) = x + 3 + 18/(x-3)

What is the division operation?

In mathematics, divides left-hand operands into right-hand operands in the division operation.

To divide using synthetic division, we follow these steps:

Write the dividend (x² +9) and the divisor (x-3) in the form of a long division problem, with the divisor (x-3) written on the outside and the dividend (x² +9) written inside the division brackets.

Write the coefficient of the first term of the dividend (in this case, 1) in the first row of the synthetic division. This will be the first term of the quotient.

Multiply the divisor (x-3) by the coefficient in the first row (1), and write the result (x-3) in the second row.

Add the second term of the dividend (9) to the result in the second row. The result is the coefficient of the second term of the quotient.

Repeat this process until you have found the coefficients of all the terms in the quotient.

Using this process, we can divide (x² +9) by (x-3) as follows:

The quotient is x + 3. The remainder is 18, so the complete division problem can be written as:

(x² + 9) / (x-3) = x + 3 + 18/(x-3)

The expression 6e2 represents the surface area of a cube where e represents the length of each edge. What is the surface area, in square centimeters, of a 5-centimeter cube?

Answers

Answer:

150 cm²

Step-by-step explanation:

The expression 6e² represents the surface area of a cube where e represents the length of each edge. What is the surface area, in square centimeters, of a 5-centimeter cube?

The surface area of a cube is expressed as: 6e²

Where e = Length of each edge

The surface area, in square centimeters, of a 5-centimeter cube

e = 5cm

Therefore, the surface area of the cube = 6 × 5²

= 6 × 25

= 150 cm²

If the ratio of the two sides of the triangles are the same then the third sides of the triangle will be parallel. Then the correct figure is D.

What is the triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

If the ratio of the two sides of the triangles are the same then the third sides of the triangle will be parallel.

⇒ 5.5/15 = 6.6/18

⇒ 0.366 = 0.366

Then the correct figure is D.

gonzalo nacio el 18 de sptiembre de 1945 si bertha nacio cuatro decadas y un lustro cual es la fecha de nacimiento de bertha​

Answers

Answer: Bertha nació el 18 de septiembre de 1990.

Step-by-step explanation:

Gonzalo nació el 18 de septiembre de 1945.

Bertha nació cuatro décadas y un lustro después.

Una década son 10 años

Un lustro son 5 años

Entonces 4 décadas y un lustro son:

4*10 años + 5 años = 45 años

Esto significa que Bertha nació 45 años después que Gonzalo.

Entonces si Gonzalo nació en 1945, Bertha nació en el año:

1945 + 45 = 1990

Bertha nació el 18 de septiembre de 1990.

La fecha de nacimiento de Bertha es el 18 de septiembre de 1990.

How many years does a decade have?

A decade is composed of 10 years. So, if there are 'x' decades, then that means there are going to be [tex]10 \times x[/tex] years in it.

For this case, we are given that:
Date of birth of Gonzelo is 18th of Sept. 1945

Bertha born after 4 decades and 5 years of Gonzelo's birth.

4 decades = 4 times 10 = 40 years

Thus, 4 decades + 5 years = 40 + 5 = 45 years.

45 years after 1945 uis 1945 + 45 = 1990

Thus, date of birth of Bertha is 18th Sept. 1990
