Step-by-step explanation:
The equation of a line is , where
is the slope and
is the
intercept.
We know that the line pass through the point (1,1) and the slope is 2.
Then,
We have to find .
If we replace the point (1,1) in we will obtain
.
Then,
The y intercept then is -1, this means that when x=0, y=-1.
We have the point (0,-1).
Now to obtain another point we have to replace with y=0.
We have the point
Now that we have to points, we have to place them in the cartesian coordinate system. And then draw the line.
Answer:
The probability that he answered neither of the problems correctly is 0.0625.
Step-by-step explanation:
We are given that a student ran out of time on a multiple-choice exam and randomly guess the answers for two problems each problem have four answer choices ABCD and only one correct answer.
Let X = <u><em>Number of problems correctly answered by a student</em></u>.
The above situation can be represented through binomial distribution;
where, n = number of trials (samples) taken = 2 problems
r = number of success = neither of the problems are correct
p = probability of success which in our question is probability that
a student answer correctly, i.e; p = = 0.75.
So, X ~ Binom(n = 2, p = 0.75)
Now, the probability that he answered neither of the problems correctly is given by = P(X = 0)
P(X = 0) =
=
= <u>0.0625</u>
