Answer:

600 sq mm

Step-by-step explanation:

I divided the shape into 2 shapes and found each shapes area and after that added both of its area to find the area of the above shape

area of rectangle= b x h

so, 15x30=450mm (square)

area of triangle= b x h (divided) 2

so, 10x30=300 (divided) by 2

= 150mm (square)

so, 450 (plus) 150= 600mm (square)

The equation e = 4 h can be used to describe this situation.
Jonah earns $20 to babysit for 5 hours.
The number of hours Jonah works depends on how much he earns.

Answers

Answer:

The equation e = 4 h can be used to describe this situation.

Jonah earns $20 to babysit for 5 hours.

Step-by-step explanation:

When Jonah babysits one hour, he earns $7.50.

looking at the graph we see at 1 hour he earns 4 dollars false

The equation e = 4 h can be used to describe this situation.

The slope is 4   so y = 4x   e = 4h  would also work   true

Jonah earns $20 to babysit for 5 hours.

Using our equation from above

e = 4*5 = 20   true

The number of hours Jonah works depends on how much he earns.

This would be false

The dependent variable is on the y axis.  The amount he earns depends on how much he works

9 + (5 + 16) - 12

9 + 21 - 12

30 - 10 - 2

20 - 2

18

Answer:

18

Step-by-step explanation:

First what you would do is plug in the numbers.

3x3+(5+2x8)-12

Then you would multiply 2 times 8 and get 16. Then add 16 and 5 and get 21.

3x3+(21)-12

Then you add 3 times 3 and get 9.

9+21-12

Then you solve left to right. Then you add 9 and 21 and get 30. Last you subtract by 30 by 12 and get 18.

Answers

Answer:

The representative sample contained more girls than boys.

Step-by-step explanation:

A "sample" of something is a small part of it. A "representative sample" is a small part of the students that represents them all. A random sample would not include all 160 students. It is more likely that there would be more girls than boys, than more boys than girls. In total, there are more girls than boys: 95 girls to 65 boys. It is more likely that a sample of the total students would be just like the total, but smaller.

B. 22x + 46y
C. 22x + 42y
D. 51x+ 42y​

Answers

Answer:

The answer would be D.

Step-by-step explanation:

All you have to do is combine like terms.

Pretend that the parenthesis aren't there. 13x + 9y + 38x + 33y.

When you combine like terms, you add or subtract the terms that have the same variable attached.

13x + 38x = 51x.

9y + 33y = 42y

51x + 42y.

equations shown below.

2x - 4y = 4

x - 2y = 8

Answers

Answer:

x = 5

y = - 3/2

Step-by-step explanation:

[tex]\left \{ {{2x-4y =4} \atop {x-2y=8}} \right.[/tex]

The augmented matrix is :

[tex]\left[\begin{array}{ccc}2&-4&4\\1&-2&8\\\end{array}\right][/tex]

Now; to Row operations

Swap row 2 to row 1

[tex]\left[\begin{array}{ccc}1&-2&8\\\\2&-4&4 \end{array}\right][/tex]

Multiply row 1 with 2 and add to row 2 ;

1(2) = 2

-2(2) = -4

8(2) = 16

2 +2  = 4

4 +(-4) = 0

16+ 4 =20

Now; we have:

[tex]\left[\begin{array}{ccc}1&-2&8\\\\4&0&20 \end{array}\right][/tex]

changing row 2 back to equation form:

4x + 0y = 20

4x = 20

x = 20/4

x = 5

substituting x = 5 in row 1

x - 2y = 8

5 - 2y = 8

-2y = 8 -5

-2y = 3

y = - 3/2

You have gained confidence and skill at pulling data and you are not making as many rookie mistakes. The college executives are begging to take notice of your skills. The college has had serious problems with reporting in the past for several reasons. One problem is there was no centralized department for numbers. Human Resources did some reporting, financial aid another, and the rest was covered by the registrars office. It was difficult to determine simple things like number of students enrolled in the fall semester because different departments would generate different. The higher ups want one consistent number they can rely on and they think your department should be in charge of generating that number. As the first report as the official office numbers they want you to generate a report that tracks student demographics over time (a longitudinal study). Your college has a large percentage of its student body who are affiliated with the military (active duty military, retired military, military spouse, military dependent). For this study the college executives want to see how they stack up to other colleges that have a large percentage of military students. After doing some research you find a field in the database that named mil_status. The documentation you have on the field says this is the field you are looking for. Since you need to determine when the student was in the military to generate this report you look for a start and end date associated with mil_status. Sure enough the table also has a mil_status_start and a mil_status_end field. These fields when combined with enrollment data allow you to determine if a student was in the military when they were a student. You query the data to check for bad dates and discover a serious issue. Most of the start dates and end dates are NULL. You once again make some quick phone calls to find out whats going on. It seems this field is not populated unless the college receives official paperwork from the military listing the soldiers enlistment date. In addition to this you find out that students are not required to update their information ever semester. This means once their mil status is set it is unlikely to ever change. Based on this information prepare a post that addresses the following: 1) What recommendation(s) would you make to the colleges executives to address this issue? 2) Collecting this data will have tangible and intangible costs associated with it. For example requiring official paper work adds an extra burden on registration and on the student. Students may decide to go elsewhere instead of supplying the paperwork or may stop identifying themselves as military. The executives want the data but they dont want its collection to impact enrollment or place an undue burden on registration (the line is long enough already). How would you respond to these concerns?3) You noticed something odd in the mil_Status field. The possible values are "Active Duty Military", "Military spouse", "Retired military", "Military Reserves", and "Military dependent". In what way is this field problematic?
