2. (3) - eye color is non-numerical (blue, green, gray, brown, and so on)

3. (2) - mean is the best measure, because the problem statement tells you that you want to compare "the average amount of time". You could argue that the median might more fairly represent a "typical" time spent exercising, but that is not what the question tells you to compare.

4. (4) 0.90. The data has a positive slope, so r > 0. It falls close to a line, so the correlation is closer to 1 than to 0.

Is it possible to use latex using the dollar syntax here?
natta225 [31]

Step-by-step explanation:

No, the LaTeX that the app uses starts and ends with the [ tex ] and [/ tex ] tags (without the spaces). In (1), simply remove the \latex tag and the integral will appear in embedded form:

\int_a^b f(x)\, dx

This is meant to maintain the line spacing. If you want show the full size of the integral (or in display mode), add the \displaystyle tag after the [ tex ] like this

[ tex ]\displaystyle \int_a^b f(x)\, dx[/ tex ]

and the integral will look like this

\displaystyle \int_a^b f(x)\, dx

after removing the spaces in the [tex] tag. This works also for sums and product of a series and limits.

How do you write 0.045 as a reduced fraction
Anvisha [2.4K]
0.045 = 45/1000

Divide top and bottom by their greatest common factor.
It looks to me as though the greatest common factor of  45  and  1,000  is  5 .
Divide top and bottom by  5  and we have  <u>9/200</u> .  That's the simplest form.

Order the expressions from least value to greatest value.<br> I added a screenshot
Ivanshal [37]
-4.8x3.2 , 4.32/-3 , -2 3/5 - (1 2/5), 2 1/4+(-1 2/5)

So basically if they’re numbered from left to right then it would be 1, 3, 4, 2.

Problem 1 has a solution of -15.36
Problem 2 has a solution of 0.85
Problem 3 has a solution of -1.44
Problem 4 has a solution of -1.2

In order -15.36 would be the least greatest, because it is the farthest from zero. Followed by -1.44, -1.2, and lastly 0.85.
