An experimenter is randomly sampling 4 objects in order from among 43 objects. What is the total number of samples in the sample
Ivenika [448]

Answer:

10.75

Step-by-step explanation:

First you see how many times 4 can go into 4 in the tens place which is 1 .You multiply 4 times 1and you get 4 .Then you minus 4 from 4 and get

Then you bring down the 3 and see how many times 4 can go into 3 which is 0 .So you put a decimal point and bring down a 0.

See how many times 4 can go into 30,which will be 7 times.After , you multiply 7 times 4 and you get 28.Subtract 29 from 30 and you get 20.You bring down the 0 .

See how many times 4 can go into 20 which is 5.Mutiply 5 times 4 and get 20 then subtract 20 from 20.

Get a final quotient of 10.75.

Help please anyone one?
fiasKO [112]

So in a gallon there is 4 quarts, and in 1 quart there are 2 pints and in 1 pint there are 2 cups.

So for the 1 quart of onion that would equal 4 cups. Then for the 4 pints of broth there would be 8 cups and then the 6 cups and 2 cups just stay the same. So if you add those number of cups up you would get 20 cups. Divide that by 4 to see how many bowls she would need.

<em><u>The answer is she would need 5 bowls </u></em>

At a peace summit, seven Hatfield and nine McCoy family
katrin2010 [14]

Answer:

0.525 = 52.5% probability that the two are from different families.

Step-by-step explanation:

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

In this problem, the order in which the two participants are selected is not important, so we use the combinations formula 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:

1 from the Harfield family(from a set of 7).

1 from the McCoy family(from a set of 9). So

D = C_{7,1}*C_{9,1} = \frac{7!}{1!6!}*\frac{9!}{1!8!} = 7*9 = 63

Total outcomes:

2 from a set of 16. So

T = C_{16,2} = \frac{16!}{2!14!} = 120

Probability:

p = \frac{D}{T} = \frac{63}{120} = 0.525

0.525 = 52.5% probability that the two are from different families.

The population of a town increased from 3650 in 2006 to 5400 in 2009. Find the absolute and relative (percent) increase.
adell [148]

Answer:

The absolute increase was of 1750.

The relative increase was of 47.95%

Step-by-step explanation:

Absolute increase:

The absolute increase is the final population divided by the initial population.

Initial population: 3650 in 2006

Final population: 5400 in 2010

5400 - 3650 = 1750

The absolute increase was of 1750.

Relative increase:

The relative increase is the absolute increase divided by the initial population, then multiplied by 100(to answer as a percentage):

Absolute increase: 1750

Initial population: 3650

1750/3650 = 0.4795

The relative increase was of 47.95%
