Answer:
The probability of not spinning a 5, flipping heads, then spinning a 1 is 0.08
Step-by-step explanation:
I may assume the spin contains 5 numbers ( plz change and recalculate if the no. of numbers is different)
P(not spinning a 5) = 4/5
P(flipping head) = 1/2
P(spinning 1) = 1/5
P(not spinning a 5, flipping heads, then spinning a 1)= 4/5 * 1/2 * 1/5 = 0.08 = 0.1
It would be B. 120 you would usually round up but the closest one to 129.02083 is 130 and since there is no 130 it would be 120
Answer:
Part A is 34
Part B is 2
Step-by-step explanation:
This question did provide some clues to answer this question. Every week, the area covered by the algae is multiplied by 2^1.
To find the area cover increase by the algae per day, the exponent should be divided by 7 since there are 7 days in a week. Hence, every day, the area covered by the algae multiplies by 2^(1/7). In other words, 1 day after the algae was spotted, the area is 12.5 * 2^(1/7), which answers part B.
10 days after the algae was spotted, the area covered by the algae is 12.5 * 2^[(1/7)*10] = 33.6475... , which rounds up to 34 and answers part A.
