First job = 3 pennies
Second job = 9 pennies
Third job = 27 pennies
Do you see the pattern? The pennies are being multiplied by 3 every job or tripling.
Fourth job = 81 pennies
Fifth job = 243 pennies
Sixth job = 729 pennies
Seventh job = 2,187
So the answer would be that after the seventh shoveling job you'd receive 2,187 pennies.
Answer:
1. Cluster sampling
2. When finding a fair sample
3. Simple random sampling
Answer:
Step-by-step explanation:
Given that the Pick 4 games in many state lotteries announce a four‑digit winning number each day. Each of the 10,000 possible numbers 0000 to 9999 has the same chance of winning. You win if your choice matches the winning digits. Suppose your chosen number is 3079 .
a) The probability that the winning number matches your number exactly
= 1 out of 10000 = 0.0001
b) the probability that the winning number has the same digits as your number in any order
This includes 0379, 0397, 0739, 0793, 0937, 0397 i.e. starting from 0 there are 6 = 3! ways
Or 3079 can be arranged in 4! ways = 24
Favorable outcomes = 24
Prob of winning = 24/10000 = 0.00024
=0.0002
-20 because 3x+178=6x+238
