The mean age of 5 people in a room is 40 years.

1 answer:

7 0

Answer:

22years

Step-by-step explanation:

The sum of ages of people in the room is 40 * 5= 200

[ Remember mean = total ahead of people/ number of people]

Let the age of the 6th person be X

200+x. / 6 = 37

200 + x = 37 * 6 = 222

x = 222- 200 = 22

Step-by-step explanation:

A tangent line is a line that only intersects a circle at one point.

LG and CJ are not lines, and GH intersects the circle twice (at point G and point H), so JM is the tangent line.
