I believe a qualitative prediction requires a prediction with out any numerical data to support it while a quantitative predictions require a prediction supported by numerical data.

A real world example of this is in chemistry during a lab. qualitative data is based off of observation with out numerical data such as a color change. quantitative data is based off of observation with numerical data such as the mass changes.

(quantitative prediction is decision from data based on percentages, probabilities, and so on while qualitative predictions are based off of given information).
I hope this helps and let me know if you need further explaining.

The population of a town has grown at an annual rate of 2.7%. How long does it take for it’s population of 18,450 people to doub

charle [14.2K]

It would take 26 years.

The equation will be in the form y = a(1+r)ˣ, where a is the initial population, r is the growth rate as a decimal number, and x is the amount of time. Using our information we have

y = 18450(1+0.027)ˣ = 18450(1.027)ˣ

We want the population to be doubled; 18450*2 = 36900:
36900 = 18450(1.027)ˣ

Divide both sides by 18450:
36900/18450 = 18450(1.027)ˣ/18450
2 = 1.027ˣ

Using logarithms, we have
$\log_{1.027}2=x
\\
\\x=26.017$

Which table represents the same linear relationship as the equation y = 5x + 7?

Nataly_w [17]

I can’t see the image. I’ll still try to help. The line has to cross 7 on the y-axis (|). The line is positive so it should look something like this “/“ By doing rise over run, (5/1) It is supposed to go up 5 times for every one time it goes to the right. Sorry if this explanation is a little confusing. This is the most I can do without seeing the image.

Help asap algebra 6th grade 50 points

Eva8 [605]

45x = 180

divide by 45

x=4

yes

420 /d = 30

multiply by d

420 =30d

divide by 30

14 =d

no d=14

37+s = 80/2

37+s =40

subtract 37 from each side

s =3

no s=3

52+g =45+11

52+g = 56

subtract 52 from each side

g=4

no g=4

13+14 = 3f

27 = 3f

divide by 3

9=f

yes f=9
