Mean = np = 60(0.7) = 42

Answer:
3 * 10 ^-2
Step-by-step explanation:
When we divide numbers in scientific notation first divide the number portion
2.7 /9 =.3
Then divide the exponents
10 ^5 / 10 ^6 = 10 ^ (5-6) = 10 ^ -1
.3 * 10 ^-1
We cannot leave the .3 since the first number has to be between 1 and less then 10
Move the decimal 1 place to the right which means subtract 1 from the exponent
3 * 10 ^-2
