Okay so the mean is 3, standard deviation is 2.16 and the variance is 4.66.
<u>Answer:</u>

<u>Step-by-step explanation:</u>
------------(1) (given)
-------------(2) (given)
so,
f(x) = h(g(x)) (given)
=
-----(from (1) and (2))
⇒
-----(taking g(x) = k)
⇒
is the function.
(2) 2x
Bc you’re adding the imaginary one infront of the x.
(1) X squared + 25
Distribution
(3) 15x-30
Distribution
(1) x to the 6 power
You add the powers when they are being multiplied
(2) 2x squared + 7x + 12
Foil method
(2) 9x + 20
Adding Like terms
(4) 12x + 25
Adding and multiplying like terms
(2) 19x + 7
Multiplying then adding like terms.
I hope this helps ;)
Mark me brainliest please! ;D
