The mean age of 12 women in an office is 26 years old. The mean age of 4 men in an office is 29 years old.
What is the mean age (nearest year) of all the people in the office

27

Step-by-step explanation:

Well, if the mean of 12 people is 26, you can imagine those 12 people are 26, so 26*12=312. Next, you do the same for the 4 men, so 29*4=116. Then you add those 2 numbers together, to get the total of 428. Divide that by the total amount of people in the office which is 428/16=26.75. Rounding up (because the decimal starts with a number above 5) you get that the average age is 27.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
