Prove that 3:8 is eqivalent tp 12:32
kifflom [539]
3:8 can also be written as 3/8

12:32 can also be written as 12/32

\frac{12}{32} = \frac{3\times 4}{8\times 4} = \frac{3}{8}

So thus 3:8 is equivalent to 12:32

What is the median of the data set? {23, 19, 20, 17, 22, 15, 25, 18, 17, 18, 24, 21}
zlopas [31]
First put the numbers in order, least to greatest.
15, 17, 17, 18, 18, 19, 20, 21, 22, 23, 24, 25
Count the amount of number in the data set. In this one there is 12. Since 12 is an even number, the media will not be in the data set because there is no possible way to have the same amount of numbers on each side. SO, count 6 numbers in to the data set (which would be 19). Next to that is 20. Add 19+20=39. Divide 39 by 2 (2 numbers), which is 19.5
The median of this data set is 19.5
Hope I helped :)

If f (x) = 2 x + 5 and three-halves are inverse functions of each other and f (x) = 2x + 5, what is
marusya05 [52]

Answer:

See explanation

Step-by-step explanation:

The question has conflicting details

f(x) = 2x + 5

f(x) = 2x + 5 and three halves doesn't sound correct.

So, I will take f(x) as

f(x) = 2x + 5

Next, solve for the inverse function

Replace f(x) with y

y = 2x + 5

Swap x and y

x = 2y + 5

Make 2y the subject

2y = x-5

Make y the subject

y = \frac{x-5}{2}

Replace y with the inverse sign

f^{-1}(x) = \frac{x-5}{2}

So, now we can calculate any value from the original function and from the inverse function.

For instance:

f^{-1}(7) = \frac{7-5}{2} = \frac{2}{2} = 1

f(1) = 2*1 + 5 = 2+5=7
