If the CPI (consumer price index) of 141 increased 8.3 % this year. What was the end of year CPI?

1 answer:

4 0

If the CPI increased by 8.3%, therefore this means that there was a fractional increase of 0.083. So amount increased is:

CPI increase = 141 * 0.083 = 11.703

Therefore the end of year CPI is the sum of the original and the increase:

end of year CPI = 141 + 11.703 = 152.703

Answer:

152.703

Determine a pair of angles (one positive and one negative) in degree measure coterminal to the angle 117°.

andre [41]

Answer:

Option B.

Step-by-step explanation:

When we have an angle A, in degrees, the coterminal angles are all the angles that can be written as:

B = A + n*360°

Where n is a positive or a negative integer (if n = 0, then B = A, which means that A is coterminal with itself, which is trivial).

Now we want to find two coterminal angles to 117°, such that one is positive and the other negative.

Then we can do:

for the positive one, use n = 1.

B = 117° + 1*360° = 477°

For the negative one, use n = -1

B = 117° - 1*360° = -243°

Then the two angles are 477° and -243°

The correct option is B.

A real estate agent has 17 properties that she shows. She feels that there is a 50% chance of selling any one property during a

Likurg_2 [28]

Answer:

0.0011 = 0.11% probability of selling less than 3 properties in one week.

Step-by-step explanation:

For each property, there are only two possible outcomes. Either they are sold, or they are not. The chance of selling any one property is independent of selling another property. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
