In a survey of 250 people 180 like farming ,120 like civil service and every people like at least one occupation .Draw a Venn diagram and find the number of people who like farming as well as civil service. Also find how many people like onley civil service

Step-by-step explanation:

Given

We have:

Add the first two equations and subtract the third one to get the number of people who like both:

Now find the value of C - B, civil service only:

The diagram will look like this:

Farming    |   Both (intersection)  |  Civil services

    130        |           50                     |         70

y = -4x - 24

Step-by-step explanation:

Firstly, figure out the slope. To do that, plug the coordinates in the formula.

y2 - y1 / x2 -x1

= -24 - 0 / 0 - (-6)

= -4

The slope is -4/1x.

To figure out the y-intercept, you need to plug one of the coordinates into

y = -4x + b

0 = -4(-6) + b

0 = 24 +b

-24 = b
