Answer:
log 12 = 1.0791
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the logarithmic function is log12
We will apply the formula
log by = log b + log y
log xⁿ = n log x
<u><em>Step(ii):-</em></u>
log 12 = log 4 × 3
= log 4 + log 3
= log 2² + log 3
= 2 log 2 + log 3 (∵ log xⁿ = n log x)
= 2× 0.3010 + 0.4771
= 1.0791

I am not understanding why your teacher 14.3 is wrong. Please check whether the weight of 4 pumpkins is correct or not.
3. We are given that on average 5 passengers will board the bus at each of the 6 stops.
Let x be the number of passengers board the bus at the sixth stop.
Therefore, the average is:




Therefore, 7 passengers need to board the bus at the sixth stop for Leah's prediction to be true.
