Answer:

  x = 7

Step-by-step explanation:

The relevant trig relation is ...

  Sin = Opposite/Hypotenuse

  sin(30°) = x/14

  x = 14·sin(30°) = 14·0.5 . . . . . multiply by 14 and evaluate

  x = 7

_____

<em>Additional comment</em>

The triangle shown is a 30°-60°-90° triangle. The ratios of sides, shortest-to-longest, are ...

  1 : √3 : 2

As we have seen here, the shortest side is 1/2 the length of the longest side, so x = 14/2 = 7.

This triangle and these ratios show up often, so it can be worthwhile to remember these ratios.

Answer:

0.0667 = 6.67% probability that the shares of a company that fires its CEO will increase by more than 5%.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this problem:

Event A: Company fires the CEO

Event B: Shares increase by more than 5%.

Probability of a company firing it's CEO:

35% of 100 - 4 = 96%(shares did not increase by more than 5%).

60% of 4%(shared did increase by more than 5%).

So

P(A) = 0.35*0.96 + 0.6*0.04 = 0.36

Intersection of events A and B:

Fires the CEO and shared increased by more than 5%, is 60% of 4%. So

P(A \cap B) = 0.6*0.04 = 0.024

Probability that the shares of a company that fires its CEO will increase by more than 5%.

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.024}{0.36} = 0.0667

0.0667 = 6.67% probability that the shares of a company that fires its CEO will increase by more than 5%.

A pie was cut into two equal pieces. Each of the pieces of pie was cut into halves again, and each of those smaller pieces was c
Verdich [7]

3/4

Step-by-step explanation:

If you cut a whole pie into two you get two (2) ½ pieces

1 ÷ 2 = ½

When you cut the two ½ pieces into two you get four (4) ¼ pieces;

½ ÷ 2 = ¼

When you cut the four ¼ pieces into two you get 8 1/8 pieces;

¼ ÷ 2 = ¹/8

Therefore the whole pie at this point is made up of 8 ¹/8 pieces. When two (2) of these pieces are eaten we are left with 6 ¹/8 pieces;

8 – 2 = 6

The portion of the pie left therefore is;

6 * ¹/8 pieces

= ⁶/8

= ³/4

2. Describe the means-extremes property.
GREYUIT [131]

Step-by-step explanation:

For example:

Ex: 2:3 :: 6:9

In this question, the means are 3 and 6.

The extremes are 2 and 9.

We use this method to find whether the two ratios are equal or not.

We multiply the means and the extremes, and if there products are same, then these two ratios are proportional.

If these two ratios are proportional, their "means" = "extremes"

=> Means = Extremes

=> 3 x 6 = 2 x 9

=> 18 = 18

So, these two ratios are proportional.

Hope this helps you.
