Answer:
<em>About 900 cans not stamped in 3 hours</em>
Step-by-step explanation:
<u>Proportions</u>
Sally found that 150 cans were not stamped in the 1/2 hour trial run.
Following the same proportion in time, we can say:
150 cans not stamped in 1/2 hour. Multiplying by 2:
300 cans not stamped in 1 hour. Multiplying by 3:
900 cans not stamped in 3 hours
About 900 cans not stamped in 3 hours
Answer: C

Answer:
4 times
Step-by-step explanation:
Sample space :
6 sided cube = (1, 2, 3, 4, 5, 6)
Coin = (H, T)
Probability = required outcome / Total possible outcomes
Probability of head (H) = P(H) = 1 /2 = 0.5
Probability of 3 = P(3) = 1 /6 = 0.166666
Probability of heads and 3 on a single try = p(H) * p(3) = 0.5 * 0.166666 = 0.083333
Hence, expected number of times this is likely to occur in 48 tries :
0.083333 * 48 = 4
Answer:If she buys 60 tiles, the cost at both shops is the same.
If she buys less than 60 tiles, then the second shop is cheaper.
If she buys more than 60 tiles, then the first shop is cheaper.
Step-by-step explanation:
Explanation:
Let the number of tiles be
x
At the first shop: Cost =

If the cost is the same:
1.19
x

If she buys less than 60 tiles, then the second shop is cheaper.
If she buys more than 60 tiles, then the first shop is cheaper.
