1 answer:
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 .
69 people chose vegetarian .
Than the equation becomes
L.C.M of (3,12) = 12
than
12x = 69 × 12 + 4x + 5x
12x - 9x = 828
3x = 828
x = 276
Therefore 276 people were at the wedding.

Step-by-step explanation:
Given : A circle with the same radius as the circle shown but with a center at (-1.1).
To find : Which equation represents a circle ?
Solution :
The equation of a circle with center (h,k) and radius r is given by :
Here, we are given (h,k)=(-1,1)
and radius r=4 units
So, equation of circle will be :
or
Therefore, the required equations of circle are

P(1≤x≤3) defined the probability that the result is between 1 and 3, included. You can answer this question in two ways:
1. Sum the probabilities of good events:
From the graph, we have
So,
2. Use complementary probabilities
Asking that the result is 1, 2 or 3 is the same as asking that the result is not 4. The probability that the result is 4 is 0.16, so the probability that the result is not 4 will be
The result is obviously the same.
