You can graph multiple equations in one plot by merely superimposing them. You plot the x values against the corresponding y values. Usually, you are given an equation in this form y=f(x), where f(x) is a polynomial containing a variable of x. You assign arbitrary values of x, to get the y values and plot them together as one data point.

The point at which the graphs intersect each other is the solution of the problem.

The blanks in the given passage are filled with the appropriate words as follows-

Ecology is the study of how <em><u>(1) plants</u></em>, animals, and people live <u><em>(2) together</em></u> and help each other. But man sometimes forgets he <em><u>(3) is</u></em> a part of the <u><em>(4) family</em></u> of all living things. Here is an example. A planter is <u><em>(5) talking</em></u> about killing <u><em>(6) weeds</em></u> on his land. He remembers his first <u><em>(7) experience</em></u> with a weedicide. He was a <u><em>(8) planter</em></u> then, working <u><em>(9) on</em></u> a rubber plantation. He had a problem with weeds. The cost of weeding of the <u><em>(10) fields</em></u> by hand was getting <em><u>(11) too</u></em> high. So he used a new, cheap, and effective <u><em>(12) method</em></u>, good old Sodium Arsenate. He sprayed plenty of this <em><u>(13) around</u></em> to kill the weeds. The first thing to <em><u>(14) react</u></em> were the frogs.

Thirty students in the fifth grade class listed their hair and eye colors in the table below: Brown hair Blonde hair Total Green
Mars2501 [29]

Answer:

No, the events "brown hair" and "brown eyes" are not  independent.

Step-by-step explanation:

The table that represents the  hair and eye colors of thirty students of the fifth grade are given in table as:

                         Brown hair          Blonde hair              Total

Green eyes           9                       6                               15

Brown eyes          10                       5                              15

Total                     19                        11                             30

No, the events  "brown hair" and "brown eyes" are not independent.

Since, two events A and B are said to be independent if:

P(A∩B)=P(A)×P(B)

where P denotes the probability of an event.

Here we have:

A= students having brown hair.

B= students having brown eyes.

A∩B= students having both brown hair and brown eyes.

Now,

P(A)=19/30  (ratio of addition of first column to the total entries)

P(B)=15/30  ( ratio of addition of second row to the total entries)

Also,

P(A∩B)=10/30

Now as:

P(A∩B) ≠ P(A)×P(B)

Hence, the two events are not independent.
