Answer:

I would go with C only because you have the find the median of the lower half of the data set This means that about 25% of the numbers in the data set lie below Q1 and about 75% lie above Q1.

Step-by-step explanation:

Lower quartile (xL): 26.5

Median (xm): 37

Upper quartile (xU): 44.5

Which ratio is the odd one out? <br> 10:40 or 5:20 or 1:4 or 3:12 or 8:33

Dmitrij [34]

10:40
This ratio is 10/40. Divide both by 10. You will get 1/4. 1/4 is 1:4.
So, we have one answer
1/4

5:20
This ratio 5/20. Divide both by 5. You'll get 1/4. 1/4 is 1:4
1:4

1:4 is the ratio we had before.

3:12
This ratio is 3/12. Divide both by 3. You'll get 1/4. 1/4 is 1:4
1:4

8:33
This ratio can not be reduced further.
So, the solution is 8:33 which has a different ratio from all the other ones

The inverse of F(x) is a function

Sladkaya [172]

Step-by-step explanation:

Let f be a function having domain in the set X, and range in the set Y. Then f would be invertible if there exists a function g having domain Y and range X, such as:

${\displaystyle f(x)=y\,\,\Leftrightarrow \,\,g(y)=x$

In other words, the function $f$ is applied to an input x, and gives an outcome of y, then its inverse function, let say $g$ , can be applied to y to give the result of x.
