Answer:
Step-by-step explanation:
g(x) = 3f(-2x)
= 3*([-2x)² + (-2x) - 2)
= 3 (4x² - 2x - 2)
= 3 * (4x² - 4x +2x - 2) {Rewrite the middle term}
= 3 *[ 4x(x - 1) + 2(x - 1)]
= 3* [ (x -1) *(4x + 2)]
= 3(x - 1)(4x + 2)
x - 1 = 0 ; 4x + 2 = 0
x = 1 ; 4x = -2
x = ![\dfrac{-2}{4}=\dfrac{-1}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B-2%7D%7B4%7D%3D%5Cdfrac%7B-1%7D%7B2%7D)
Roots: x = 1 , (-1/2)
Answer:
32
Step-by-step explanation:
The question can be posed as ...
24 = 75% × what
24/0.75 = what = 32 . . . . . divide by 75%
24 is 75% of 32.

Answer:
85%
Step-by-step explanation:
Let’s identify all the outcomes less than 10, that would be 2-9
The number of times the die was rolled is obtainable by adding all the frequencies ;
That would be ;
3 + 6 + 8 + 11 + 14 + 16 + 15 + 12 + 9 + 5 + 1 = 100
Now let’s add the frequencies of results which are less than 10;
That would be the frequencies of the numbers 2-9;
Thus, we have;
3 + 6 + 8 + 11 + 14 + 16 + 15 + 12 = 85
The required probability of rolling a number less than 10 = 85/100 = 0.85 which to the nearest percent is 85%
