Answer:
169 quarters
Step-by-step explanation:
Recall that 1 quarter = 25 pennies, and so the conversion factor is
1 quarter
-------------------
25 pennies
Use this conversion factor to convert 4246 pennies into quarters:
1 quarter
------------------- * 4246 pennies = 169.84
25 pennies
Obviously we cannot get our hands on 0.84 quarters, so round the above result down:
4246 pennies = 169 quarters plus 21 leftover pennies.
Answer:
20.5 years
Step-by-step explanation:
The population is given by the exponential function ...
p = 16000·(1 +0.022)^t
When p = 25000, we can find the value of t by taking logarithms.
log(25000/16000) = t·log(1.022) . . . . . divide by 16000, take the log
t = log(25/16)/log(1.022) ≈ 20.5 . . . . . . divide by the coefficient of t
It will take about 20.5 years for the population to reach 25000.
<h2>
Answer:</h2>
Option: D is the correct answer.
D. 0.45
<h2>
Step-by-step explanation:</h2>
The results of the experiment are given as follows:
Coin Experiment Side of Coin Number of Tosses
Heads 18
Tails 22
This means that total 40 experiments were performed.
( Since 18+22=40)
Also, the number of times head turn up=18
Hence, the experimental probability of getting heads is:
Ratio of number of times head turn up to the total number of experiments performed.
Hence,
Hence, the experimental probability of getting head is:
0.45
