Nimfa-mama [501]

Answer

Find out the how much people were at the wedding.

To prove

Let us assume that the people were at the wedding be x .

As given

Joy organised a large wedding .

Guests had to choose their meals from beaf ,chicken or vegetarian .

$\frac{1}{3}\ of\ the\ guests\ chose\ beaf .$

$\frac{5}{12}\ of\ the\ guests\ chose\ chicken.$

69 people chose vegetarian .

Than the equation becomes

$x = 69 + \frac{1x}{3} + \frac{5x}{12}$

L.C.M of (3,12) = 12

than

12x = 69 × 12 + 4x + 5x

12x - 9x = 828

3x = 828

$x = \frac{828}{3}$

x = 276

Therefore 276 people were at the wedding.

Answer:

1) Population

2) Sample

3) π=0.378

4) p=0.25

Step-by-step explanation:

1) The entire city of Athens is the population, as is the group of subjects about which we want to inference the mean income and proportion of citizens under the poverty line.

2) The 200 citizens from the researcher's data is the sample. It gives data to estimate information about the population, in this case, the entire city of Athens.

3) The symbol that denotes the value of 0.378 should be π, as it is a population proportion.

$\pi=0.378$
