Cross multiplication!
\frac{7}{8} = \frac{x}{24}
7 × 24 = 8x
168 = 8x

Divide both sides by 8 to isolate x

\frac{168}{8} = \frac{8x}{8}
8 and 8 cancels out

21 = x

8*?=24? 8*3=24. So multiply 7 also by 3, and the answer is 21 :)

what is the probability of rolling a 3 on two consecutive roll of a fair dice round your answer to the nearest hundred​
Wittaler [7]

Answer:

do you want probability in fraction, percent, or decimal form?

Step-by-step explanation:

their is one 3 on a regular dice which has 6 numbers

this gives you the fraction 1/6

but since you are rolling the dice twice you would have 1/6 × 1/6 giving you 1/36

if in percent form this would be 2.77777778% or rounded to 3%

and decimal form as 0.0277777778 or rounded to 0.03%

(f·g)(x) is x^5 - 5x^4 + 4x³ - x² + 5x - 4

Step-by-step explanation:

  • Step 1: Given, f(x) = x² - 5x + 4 and g(x) = x³ - 1 Find (f·g)(x)

(f·g)(x) = f(x)·g(x) = (x² - 5x + 4)(x³ - 1)

                          = x^5 - 5x^4 + 4x³ - x² + 5x - 4

                          = x^5 - 5x^4 + 4x³ - x² + 5x - 4
