Answer:

B) 45

Step-by-step explanation:

Here, ∠LOA = 45°

Also, the line AO || MN

and, LO || LO.

Thus, ∠LOA = ∠f = 45°

And, ∠f and ∠a are vertically opposite angles. So, they both will equal.

Thus, ∠a = 45°

The value of a is D)73 I think because 180-107 since a straight line is 180 u just subtract the angle from it. hope this helps.

Answer:

$(x-1)^2+(y+4)^2=9$

Step-by-step explanation:

The equation of a circle is given by:

$(x-h)^2+(y-k)^2=r^2$

Where (h, k) is the center and r is the radius.

The center of the circle is (1, -4).

And the radius is 3.

Substitute:

$(x-(1))^2+(y-(-4))^2=(3)^2$

Simplify. Thus, our equation is:

$(x-1)^2+(y+4)^2=9$

Two students taking a multiple choice exam with 20 questions and four choices for each question have the same incorrect answer o

MrRa [10]

Answer:

The Possible model is binomial distribution model.

Step-by-step explanation:

The argument that both students cheated in the exam can be proved by a hypothesis that both the students got the same answers incorrectly.

The same incorrect answers prove that both students have cheated on the test.

Therefore the sample of incorrect answers is, n = 8

Thus, the success probability, P = 0.25

Since the given condition has only two outcomes that are choosing the same answer or not choosing the same answer. Thus, this can be solved by the binomial distribution model.

So, binomial distribution with n = 8 and p = 0 .25.
