Mathematics
1 answer:
Wewaii [24]3 years ago
4 0

Answer:

-25

Step-by-step explanation:

You must first pick two points.  I picked the points of (4, 400) and (8, 300).  You can pick different points and still get the right answer.

Subtract the y's and the x's.  Divide the difference of y by the difference of x.

400 - 300 = 100

4 - 8 = -4

100/-4 = -25

The slope, or rate of change, is -25.

Which table contains ordered pairs that lie in the graph of a line but not in the graph of a linear function?
Marizza181 [45]

Answer:

B)

Step-by-step explanation:

Again, in this case, you are looking for the undefine <em>rate of change</em> [<em>slope</em>], meaning that there are repetitive x-coordinates. With that being said, you have your answer.

I am joyous to assist you anytime.

370 College freshmen were interviewed. 200 were registered for an Advanced Math class. 270 were registered for an English class
frozen [14]

Answer:

Step-by-step explanation:

To aid in understanding, draw three circles...

100 were registered for both Math and English.

50 were registered for both Sport and English but not Math.

70 were registered for Math, Sport, and English.

From here we will be able to calculate for those that signed up for only English class: Total number of students that signed up for english class

a. none signed up only for Maths (refer to attached document)

b. How many signed up for neither Math nor English meaning they signed up for only sports which is 70 from the venn diagram in the attachment.

c. How many signed up for an English class and at least one other class?

From the venn diagram:

we could have an English class and maths class - 100

we could also have an a English class and sports - 50

Thus total is 150.

d. What is the total fee for all the students enrolled in classes

From the diagram, 120 (english only and sport only) enrolled for only one class = 120 x $100 = $12,000

From the diagram, 180 (english and sport, maths and sport and english and maths) enrolled for two classes = 180 x $150 = $27,000

From the diagram, only 70 enrolled for the three classes = 70 x $200 = $14,000

Total fees = $12,000 + $27,000 + $14,000 = $53,000
