Answer:
1/216 or 0.0046
Step-by-step explanation:
Rolling a '1' one time has a probability of 1/6. Rolling a die three times and getting a '1' each time is an independent event, meaning that no roll affects the probability of a '1' happening on any other roll. When calculating probability of independent events, multiply them together. So the probability of a '1' three times in a row is...
(1/6)(1/6)(1/6) = 1/216 or 0.0046
Answer:
A
Step-by-step explanation:
A: The student incorrectly divided both sides by 35. The student should first add 10 to both sides, obtaining 35x = 15, and then divide 15 by 35, obtaining the final answer 3/7.
Answer:
18
Step-by-step explanation:
The two smaller sides are 15 and the larger one is 18
Step-by-step explanation:
9x - 2 = 5x + 54
9x - 5x = 54 + 2
4x = 56
<u>x = 14</u>
(9x - 2) + (10y + 6) = 180
(9 · 14 - 2) + 10y + 6 = 180
126 - 2 + 10y + 6 = 180
130 + 10y = 180
10y = 180 - 130
10y = 50
<u>y = 5</u>
