Answer: Try breathing in and out a few times and telling yourself that you will be fine. If this does not work, try chewing gum for a few minutes, the gum gives you something to take your mind off your nerves and also induces a focused headset. Also try to visualize yourself passing the exam with flying colors so you won't worry as much. I hope this helps and your exam goes well! Stay safe.

If 75 percent of the employees of a certain company take a winter vacation, 40 percent take a winter and a summer vacation, and

KATRIN_1 [288]

Answer:

The answer is option A : 5%

Step-by-step explanation:

We have the following information in percentage:

Employees taking winter vacation= 75

Employees taking both winter and summer vacation= 40

Employees taking none vacation = 20

We can assume the situation as following:

Winter + Summer - Both + Neither = 100

We get;

75 + Summer - 40 + 20 = 100

So, summer = 45

45 people take vacations in summer. But 40 of them take vacation in winters too.

So, people taking vacations in summer but not winter means summer only.

This is : $45-40=5$ %

Therefore, the answer is option A : 5%

Can you please help me i’ll give extra points

First, we need to solve for sin(67°) = 22/x. Multiply each side by x and divide each side by sin(67°)

x = 22/sin(67°) = 23.9

Use pythagorean theorem to find the last side.

a^2 + 22^2 = 23.9^2

a^2 + 484 = 571.21. Subtract each side by 484

a^2= 87.21. Take the square root of each side.

a = 9.3

x = 23.9 and the other side is 9.3
