Answer:
The expected value is an expression of the weighted average and can be taken as the (arithmetic) mean
As the number of trials is increased in a binomial experiment, the expected values obtained, in each of the set of trials continuously tend to the theoretical expected value
Step-by-step explanation:
Fraction of tank drops in every 10 minutes = 1/3 inches.
We need to find the expected change in the tank's water level after 2.25 hours.
Let us convert 2.25 hours in minutes.
1 hours = 60 minutes.
2.25 hours = 2.25 × 60 = 135 minutes.
<em>We need to divide 135 by 10.</em>
We get 13.5.
Now, we need to <em>multiply 1/3 by 13.5</em>, we get.
13.5/3 = 4.5 inches.
<h3>So, tank would drop 4.5 inches after 2.25 hours.</h3>
An = a1 + (n-1)*d
n = term to find = 30
a1 = first term = 20
d = common difference = 2
a30 = 20 + (30 - 1) * 2
a30 = 20 + 29 * 2
a30 = 20 + 58
a30 = 78
sn = (n (a1 + a30)) / 2
s30 = (30(20 + 78) / 2
s30 = (30(98) / 2
s30 = 2940/2
s30 = 1470 <===
Answer:
2
Step-by-step explanation:
2/3 divided by 1/3 is 6/3 simplify to 2
