a) The answer is 3/3, as that makes it a whole. Whole = 1.
b) The answer is 8 as having a denominator of 1 makes it a whole already. That's 8 wholes.
Its an eighth 1/8. hope this helps you
1.25mm x 50 = 62.5 mm Now lets change mm to meters. There are 1000 millimeters in a meter and we are only talking about 62.5 so we are not even at a single meter. Answers B and C can be eliminated.
meter decimeter centimeter millimeter (each one is ten times more or less than the previous one depending on where you start.
Since we are changing mm to m, we will get fewer. Why - try grouping any small things like 14 days - you get 2 weeks. 72 hours - you get 3 days. Notice that the number gets lower. 14---->2 and 72------->3
So we can expect our number to get smaller. The beauty of the metric system it that is based on 10 so it involves moving decimals and adding or subtracting zeros if needed.
meter dm cm mm
62.5
notice that it would take 3 "jumps" to the left to get it under the word meter. That means our decimal has to move 3 jumps to the left too. In order to do that we need to add a zero in front of the 6 in 62.5
<u>Correct answer is 0.0625 </u> which is none of the answers above - Notice that the decimal is 3 places left from where it was before (62.5).
Answer:
8, 7.92, 2.81
Step-by-step explanation:
For each Social Security recipient, there are only two possible outcomes. Either they are too young to vote, or they are not. The probability of a Social Security recipient is independent of any other Social Security recipient. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The variance of the binomial distribution is:
The standard deviation of the binomial distribution is:
In this problem, we have that:
So
Mean:
The variance of the binomial distribution is:
The standard deviation of the binomial distribution is:
Formatted answer: 8, 7.92, 2.81
