MATHEMATICS MIDDLE SCHOOL

50 points!!!!!!A survey was conducted on the salaries of 20 randomly selected college graduates with degrees in the same subject area. Each person surveyed graduated within the same 5-year period. Ten of the people surveyed attended a private university, while the other 10 people surveyed attended a public university of roughly the same size.


Private Public
First Quartile $58,000 $35,000
Second Quartile (Median) $71,000 $42,000
Third Quartile $85,000 $54,000

Based on the samples, what generalization can be made?




The top ten percent of both the private and public university graduates surveyed earned more than $60,000 annually.







The interquartile range for public universities is $19,000 more than for private universities.







The top twenty-five percent of both the private and public university graduates surveyed earned more than $50,000 annually.







The interquartile range for private universities is $27,000 more than for public universities.

Answer 1
Answer: this is a complex problem invovlving multiplue variables.
fyi 58k=50,000 kstands for kilo means 1000
so
public vs private
58k    vs     35k
71k   vs      42k  
85k  vs      54k
this data is taken from 3 parts

each number is the middle number of each part

the first one:
top 10% eanes more than 60k
very likely becase none of the private university numbers list anything over 60k

second one:
interquartile is 19k more in public than for private
71k-42k=29k, not 19 so this is not likely

third one:
top 25% earnes more than 50k
this is more likely than the others because the data is from 1/3 and 1/3=33% and we are looking for 25% which is smaller and the numbers of the median is more than 50k so this is the most likely answer


fourth one
rangefor private is 27k more than for public
false since 72k>42k not the other way around


the answer is the third option (top 25%of privat and public reaned more than 50k per year)

FACTOR OUT THE GCF:

6d^5-10d^2

Answers

Answer:

GCF: 2d²

Step-by-step explanation:

Write out all the factors of 6:

   6

-----------

6       1

3       2

Write all the factors of 10:

     10

--------------

10        1

5         2

The GFC of both of those numbers is 2.

Since both numbers have a variable of d, and since they both have exponents, you can multiply both numbers by d², because there is at least one d² in each variable.

Your full answer would be: 2d²(3d³ - 5)

If you use foil, remember you don't multiply exponents, you add them.

The quotient of a number and 3, less 8, is 16. What is the number?

Answers

Answer:

The number is 72.        

Step-by-step explanation:

Let x be the number.

We are given that the quotient of a number and 3, less 8, is 16.

Thus, we can write this in the form of equation as:

\displaystyle(x)/(3) - 8 = 16\n\n(x)/(3)-8 +8 = 16 + 8\n\n(x)/(3) = 24\n\nx = 3* 24 = 72

Thus, the number is 72.
The way I am reading this is 16=(x/3)-8. In that case, x=72. I hope that's the right way of interpreting this :)
