Cynthia is in the process of constructing two tangent line segments from a point outside circle O to circle O as shown. Which li
Allisa [31]

Answer:

(B) Segments MA and MB

Step-by-step explanation:

The tangent to the circle at a point is perpendicular to the radius of the circle drawn to the point of tangency.

Tangent at a point is unique.

Since there can be no two tangents at a point on circle, the options (b) and (c) are ruled out.

Now, if OA is perpendicular to MA, MA is the tangent else if OA is perpendicular to PA, PA is the tangent. Same is the case with point B.

Tangents from the same external point has same length.

MA = MB since they are the radii of the same circle with center M.

Hence, MA and MB meet all the requirements of the tangents.

Two angles are supplementary, and the measure of one angle is three times the measure of the other. Find the measure of the smal
docker41 [41]

Answer:

The smaller angle is 45 degrees.

Step-by-step explanation:

Angles measure 180º. If there are two angles and one of them is three times the other, you would just divide 180 by 4.

The equation would look like:

3x + x = 180

First, the x would be added together:

4x = 180

Then, divide both sides by 4:

x = 45

Suppose task B follows task A. The likelihood that a problem will occur with task A is 0.5, and the time to correct the problem
jasenka [17]

Answer:

The risk consequence of both activities is 1.6 months.

Step-by-step explanation:

We can define a randome variable D: total delay time for the project, and calculate its expected value.

This would be the risk consequence of both activities.

The expected delay time for the project is the sum of the expected delay for task A plus the expected delay for task B. It is assumed the likelihood of a problem in any task is independent of the other.

Then, each expected delay for a task is equal to the probability of a problem multiplied by the consequence (delay time).

E(D)=E(D_a)+E(D_b)=p_aT_a+p_bT_b\\\\E(D)=0.5*2+0.2*3=1+0.6=1.6

The risk consequence of both activities is 1.6 months.
