Question

The mean of x+2, x+3, x+4 and x-2 is:

​

Answer 1

Answer:

If the centre of a circle is (3, 5) and end points of a diameter are (4, 1) and

(2, y), then the value of y is

(a) 3

(b) -3

(d) 4

(c) 7

Answer 2

Given - Expression

Find - Mean

Solution - The mean of given values is (4x + 7)/4.

The mean can be calculated by the formula - the sum of all the values/total number of values.

Sum of all the values = x+2 + x+3 + x+4 + x-2

Sum of all the values = 4x + 7

Total number of values = 4

Keep the values in the formula to find the value of the mean.

Mean = 4x + 7/4

Thus, the mean of given values is (4x + 7)/4.
