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

DENIUS [597]

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

Two factories I and II produce phones for brand ABC. Factory I produces 60% of all ABC phones, and factory II produces 40%. 10%

denpristay [2]

Answer:

0.3721 or 37.21%

Step-by-step explanation:

P(I) = 0.60; P(II) = 0.40;

P(not defective I) = 0.90; P(not defective II) = 0.80

The probability that the phone came from factory II, given that is not defective, is determined by the probability of a phone from factory II not being defective divided by the probability of a phone not being defective.

$P(II|not) = \frac{P(II)*P(not_{II})}{P(II)*P(not_{II})+P(I)*P(not_{I})}\\P(II|not) = \frac{0.40*0.80}{0.40*0.80+0.60*0.90}\\ P(II|not) =0.3721 = 37.21\%$

The probability is 0.3721 or 37.21%.

A plumber has a set fee for a house call and charges by the hour for repairs. The total cost of her services can be modeled by c

Lostsunrise [7]

Answer:

1, 2 and 3

Step-by-step explanation:

Let

t -----> the number of hours the job takes

C(t) -----> the total cost for the service

we have

$C(t)=125t+95$

This is the equation of a line in slope intercept form

where

The slope m is equal to $m=125\ \frac{\$}{h}$

The y-intercept is the point (0,95) ---> The cost is $95 for the value of t equal zero (fee)

therefore

<u><em>The statements that are true</em></u>

1 a house call fee costs $95

2 the plumber charges $125 per hour

3 the number of hours the job takes is represented by t
