Answer:
Step-by-step explanation:
circumference for A=2π×12=24π
linear velocity=24π÷6=4π cm/sec
circumference for B=2π×15=30π
linear velocity=30π÷6=5π cm/sec
Answer:
Here is the answer: sin(3π/2) = -1
So 3π/2 is the correct choice.

3.4 in words is: Three and four tenths
3.4 in expanded form 3+4/10
</span><span><u>Explanation</u>
Decimal points are fractions whose denominator is 10 or a power of 10. To write a decimal point in words we must be able to identify the place value of every digit.
3.4
3 is a whole number and its place value is ones and the place value of 4 is tenth.
So, 3.4 in words is: Three and four tenths
3.4 in expanded form 3+4/10</span></span>
There is a 0.9968 probability that a randomly selected 50-year-old female lives through the year (based on data from the U.S. Department of Health and Human Services).
-------------------
A Fidelity life insurance company charges $226 for insuring that the female will live through the year. If she does not survive the year, the policy pays out $50,000 as a death benefit.
From the perspective of the 50-year-old female, what are the values corresponding to the two events of surviving the year and not surviving?
----
Ans: -226 ; 50,000-226 = 49774
-------------------------
If a 50-year-old female purchases the policy, what is her expected value?
WORK TRIED:
In the event she lives, the value is -$226. In the event she dies, the value is $49,774.
----
E(x) = 0.9968*(-226) + 0.0032(49774) = -$66
