Answer:
468
Step-by-step explanation:
Formula for infinite sum of geometric series is;
S_∞ = a1/(1 - r)
Where;
a1 is first term
r is common ratio
We are given;
a1 = 156
r = ⅔
Thus;
S_∞ = 156/(1 - ⅔)
S_∞ = 156/(⅓)
S_∞ = 468
Answer:
Step-by-step explanation:
We know (Ohm second law) that where k inlcudes the rest of the parameters (material, lenght). In our situation we have k= . The moment the diameter becomes 8mm R becomes
35.4% expressed as a decimal is .354
*Anchor: if you got 100% on your test, you got 1 whole test right.
Notice how I moved the decimal back two places to change 100% to 1
*An anchor is something that helps you remember what to do in the future. Use the anchor above to help you remember which way to move the decimal point when you change a percent to a decimal.

Step-by-step explanation:
Let be the total amount of money paid by any given set of passengers. If there are passengers in a car, then the driver must pay a toll of .
Then has first moment (equal to the mean)
and second moment
Recall that the variance is the difference between the first two moments:
