Answer: It is C.

Step-by-step explanation:

When you are dividing fractions, you should always flip the numerator and denominators for the second fraction. After flipping the second fraction, you should multiply the first fraction and the second fraction together.

Example: 1/3 divided by 2/5= 1/3 x 5/2= 5/6

Suppose you earn $6 per hour at your part time job what will your new rate be after a 2.5% raise

ivanzaharov [21]

2.5% means 0.025 .
After an increase of 2.5%, the new rate is (1.025) x (the old rate).

1.025 x $6.00 = $6.15 per hour.

If you work a full 40 hours in some week, you will be blessed with
a full $6 more for the week of toil than you would have collected
at the old rate.

You were not overpaid before the raise, and you must not allow
your boss to act as if you should kiss his ring or prostrate yourself
before him in return for 2.5% . It was not too long ago that 2.5% was
tantamount to being shown the way to the door, and a tacit suggestion
that you consider following in the way of the arrow.

The image of the point ( 0 , 7 ) (0,7) under a translation is ( − 2 , 5 ) (−2,5). Find the coordinates of the image of the point

avanturin [10]

Given:

The image of the point (0,7) under a translation is (−2,5).

To find:

The coordinates of the image of the point (5,−2) under the same translation.

Solution:

It is given that, the image of the point (0,7) under a translation is (−2,5). Here, the x-coordinate decreased by 2 and the y-coordinate decreased by 2 so the rule of translation is:

$(x,y)\to (x-2,y-2)$

Using this rule of translation, the image of (5,−2) is

$(5,-2)\to (5-2,-2-2)$

$(5,-2)\to (3,-4)$

Therefore, the coordinates of the image of the point (5,−2) under the same translation are (3,-4).

The lifetime of LCD TV sets follows an exponential distribution with a mean of 100,000 hours. Compute the probability a televisi

kondaur [170]

Answer:

0.9

0.3012

0.1809

230258.5

Step-by-step explanation:

Given that:

μ = 100,000

λ = 1/μ = 1 / 100000 = 0.00001

a. Fails in less than 10,000 hours.

P(X < 10,000) = 1 - e^-λx

x = 10,000

P(X < 10,000) = 1 - e^-(0.00001 * 10000)

= 1 - e^-0.1

= 1 - 0.1

= 0.9

b. Lasts more than 120,000 hours.

X more than 120000

P(X > 120,000) = e^-λx

P(X > 120,000) = e^-(0.00001 * 120000)

P(X > 120,000) = e^-1.2

= 0.3011942 = 0.3012

c. Fails between 60,000 and 100,000 hours of use.

P(X < 60000) = 1 - e^-λx

x = 60000

P(X < 60,000) = 1 - e^-(0.00001 * 60000)

= 1 - e-^-0.6

= 1 - 0.5488116

= 0.4511883

P(X < 100000) = 1 - e^-λx

x = 100000

P(X < 60,000) = 1 - e^-(0.00001 * 100000)

= 1 - e^-1

= 1 - 0.3678794

= 0.6321205

Hence,

0.6321205 - 0.4511883 = 0.1809322

d. Find the 90th percentile. So 10 percent of the TV sets last more than what length of time?

P(x > x) = 10% = 0.1

P(x > x) = e^-λx

0.1 = e^-0.00001 * x

Take the In

−2.302585 = - 0.00001x

2.302585 / 0.00001

= 230258.5
