Answer:

D. 11.1

Step-by-step explanation:

We have been given an image of a circle. We are asked to find the measure of segment AD.

Upon looking at our given image, we can see that AD and AE are intersecting secants of our circle and they intersect inside the circle.

We will use intersecting secants theorem to solve for AD. According to this theorem the product of AD and AB will be equal to product of AE and AC.

AD\times AB=AE\times AC

AD\times 7=13\times 6

\frac{AD\times 7}{7}=\frac{13\times 6}{7}

AD=\frac{78}{7}

AD=11.14285714

AD\approx 11.1

Therefore, length of AD approximately 11.1 units and option D is the correct choice.

Solve for x.<br> Greatly appreciate all efforts :)
Lelu [443]

Answer:

x = 11

Step-by-step explanation:

ΔLKM is an equilateral because a triangle with all 3 sides that are congruent is an equilateral triangle.

Angles in an equilateral triangle are all 60°.

Thus, ∠L = 60°.

=> 3x + 27 = 60

=> 3x = 33

=> x = 11

The Venn diagram shows the results of two events resulting from rolling a number cube.
tankabanditka [31]

Answer:

P(A|B)=\frac{2}{3}

P(A)*P(B)=\frac{1}{3}

P(A) =\frac{2}{3}

P(B) =\frac{1}{2}.

Step-by-step explanation:

We use the Venn diagram to calculate the desired probabilities.

Note that there are 6 possible results in the sample space

S = {1, 2, 3, 4, 5, 6}

Then note that in the region representing the intercept of A and B there are two possible values.

So

P (A\ and\ B) = \frac{2}{6} = \frac{1}{3}

In the region that represents event A there are 4 possible outcomes {4, 5, 1, 2}

So

P(A) = \frac{4}{6} = \frac{2}{3}

In the region that represents event B there are 3 possible outcomes {1, 2, 6}

So

P(B) = \frac{3}{6} = \frac{1}{2}.

Now

P(A | B)=\frac{P(A \ and\ B)}{P(B)}\\\\P(A | B)=\frac{\frac{1}{3}}{\frac{1}{2}}\\\\P(A|B)=\frac{2}{3}

P(A)*P(B)=\frac{2}{3}*\frac{1}{2}=\frac{1}{3}
