Aidan will roll a fair 10-sided number die showing the numbers 1 – 10. If Aidan rolls the number die exactly 300 times, which statement is the best
prediction about the outcome?

A. Aiden should expect a multiple of 3 to be rolled 100 times.
B. Aiden should expect a 2 to be rolled 60 times.
C. Aidan should expect a multiple of 2 to be rolled 150 times.
D. Aiden should expect a 4 to be rolled 75 times.

Aiden should expect a multiple of 2 to be rolled 150 times.

Step-by-step explanation:

300 can be divided evenly 2 times.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
