When calculating simple interest, what must you do if you want to invest for months or weeks instead of years? a. Simple interest only pays yearly, so you should find another investment. b. The simple interest calculation does not use those units, so you should just calculate as normal. c. The units have changed, so the interest formula switches to I·t=P·r. d. Interest rates are annual, so you must convert the units into years
Answers
Explanation:
Interest rates are given as an annual percentage rate. If you are investing for months or weeks, you will need to convert your units. You would divide the number of months by 12, since that would be the portion of a year it represents. For example, 3 months is 3/12 months, or 3/12 of a year. Similarly, if you were investing for weeks, you would divide by 52; if you want to invest for 6 weeks, that is 6/52 weeks, or 6/52 of a year.
Answer:
D

Final answer:
By applying the distributive property to the expression 1/4(4f-8), we get the simplified form of the expression as f - 2.
Explanation:
To simplify the expression using the distributive property, you need to multiply the term outside the parenthesis by each term inside the parenthesis. In this case, the term outside the parenthesis is 1/4. So, you would multiply 1/4 by 4f and 1/4 by -8. Doing this gives you:
1/4 * 4f = f
1/4 * -8 = -2
Therefore, 1/4(4f-8) simplifies to f - 2.
The question asks us to simplify the mathematical expression 1/4(4f-8) using the distributive property. To use the distribitive property, you distribute or multiply the 1/4 to each term within the parenthesis.
So, 1/4 * 4f is equal to f, while 1/4 * -8 is equal to -2. Therefore, the simplified form of 1/4(4f-8) becomes f - 2.

To calculate Cedric's total straight pay for the past two weeks, we need to multiply the number of hours he worked by his hourly wage.
Cedric worked 33.25 hours and earns $13.25 per hour.
To find his total straight pay, we multiply the number of hours worked by the hourly wage:
33.25 hours * $13.25/hour = $439.06
Therefore, Cedric's total straight pay for the past two weeks is $439.06.

The probability that noerrors will be found is 0.
The probability of finding more than 30 errors is 0.0001.
The probability of finding fewer than 15 errors is 0.9452.
What is probability?
It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
The number of errors in a 3,000-word passage follows a Poisson distribution with a mean of 12 errors.
i.e
Since 3,000 is six times 500.
a)
The probability that no errors will be found.
P(X = 0) = x
/ 0!
= 0.000006
Rounded to four decimal places.
= 0.0000.
b)
The probability of finding more than 30 errors.
P(X > 30) = 1 - P(X ≤ 30)
We can use a Poisson table.
P(X ≤ 30) = 0.9999.
P(X > 30) = 1 - 0.9999
= 0.0001
Rounded to four decimal places.
= 0.0001.
c)
The probability of finding fewer than 15 errors.
P(X < 15) = P(X <= 14)
= ∑(k=0 to 14) x
/ k!
From the Poissontable.
P(X ≤ 14) = 0.9452
P(X < 15) = P(X ≤ 14)
= 0.9452
Rounded to four decimal places.
= 0.9452.
Thus,
The probability that no errors will be found is 0.
The probability of finding more than 30 errors is 0.0001.
The probability of finding fewer than 15 errors is 0.9452.
