71 is the answer your welcome
an =a1+ d(n-1)
a1 = 1st term = 3
d = common difference = 7-3 = 4
an = 3 + 4(n-1)
n= term interested in
a37 = 3 + 4(37-1)
a37 = 3+4*36
a37 = 3 +144
a37 = 147
In this question, you are asked to do rounding. The number will be rounded up if 1 digit below them is having value 5 or more. The number will be rounded down instead if 1 digit below it was 4 or less. In this case, you need to round up to nearest liters which mean the nearest one. The number is 103.468.
One digit below one will be the 0.4. Since the value is 4, which was lower than 5, then the number is rounded down. So the answer would be 103.
Sheldon would have $21,386, while Howard would have $20,073.
The equation for each of these will be in the form
,
where A is the total amount in the account, p is the principal invested, r is the interest rate expressed as a decimal number, and t is the amount of time.
For Sheldon:
A=15000(1+0.03)¹²=15000(1.03)¹²=21386.41≈21386
For Howard:
A=15000(1+0.06)⁵=15000(1.06)⁵=20073.38≈20073
<span>B. We can use Bernoulli trials to find how likely is that the majority of a group of 120 people have type A blood, given that 43% of people have type A blood. There are two possible outcomes (a person eithr has Tpe A blood or does not), there is a constant probability of success (43% of people have Type A blood), and the trials are independent (wether each person has Type A blood does not depend wether others have Type A blood).</span>
