The fractions in this equation are 3/4 and 5/6. The denominators of those fractions are 4 and 6. The lowest common multiple (LCM) of the numbers 4 and 6 is 12. The LCM is 12 because this is the smallest multiple 4 and 6 have in common

Multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, 32, ....

Multiples of 6 are: 6, 12, 18, 24, 30, 36, 42, 48, ....

The LCM has been highlighted in bold to make it easier to spot

Therefore, the LCD (lowest common denominator) of the fractions is 12. If we were to multiply both sides of this equation by the LCD, then we will clear out the fractions entirely to have whole numbers only left over.

An important problem encountered by personnel directors and others faced with the selection of the best in a finite set of eleme

SVETLANKA909090 [29]

Answer:

1.63% probability that the 10 selected include include all the best 5 engineers in the group of 20

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the engineers are selected is not important, so the combinations formula is used to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Desired outcomes:

10 engineers selected from a set of 20.

5 best, from a set of 5.

Other 5, from a set of 20-5 = 15.

$D = C_{5,5}*C_{15,5} = \frac{5!}{5!(5-5)!}*\frac{15!}{5!(15-5)!} = 3003$

Totao outcomes:

10 engineers selected from a set of 20.

$T = C_{20,10} = \frac{20!}{10!(20-10)!} = 184756$

Probability:

$p = \frac{D}{T} = \frac{3003}{184756} = 0.0163$

1.63% probability that the 10 selected include include all the best 5 engineers in the group of 20

Your leg has an endpoint of A at the top of your thigh, and endpoint C at your ankle. Imagine the length of your entire leg (fro

Ludmilka [50]

Answer: 25 inches

Step-by-step explanation:

Let's imagine that this line is the leg A______________B________C

x 11

|___________36____________|

From A to C = 36 inches

From B to C = 11 inches

To find A to B all we have to do is subtract the knee to ankle length (11) from total leg length (36), which 36 - 11 = 25 inches.

Josh's monthly fuel expenses are $1,050.

<h3><u>Prices</u></h3>

Given that Josh is looking to get a new car because he decided he was spending too much on gas, and over the past year he found that he drove 7,700 miles, and at current gas prices of $4.5 he was getting about 27 miles per gallon, To determine, if he bought a vehicle that realizes 33 miles per gallon, what might be a reasonable estimate of monthly gas costs, the following calculation must be made:

27 = 100
33 = X
3300 / 27 = X
122.22 = X
122.22 = 100
100 = X
10000 / 122.22 = X
81.81 = X
(7700 / 33) x 4.5 = X
233.33 x 4.5 = X
1050 = X

Therefore, Josh's monthly fuel expenses are $1,050.
