Answer:

<em>18.2°, 161.8° and 378.2°</em>

Step-by-step explanation:

Given the expression:

8 sin x = 2.5

Divide both sides by 8

sinx = 2.5/8

Sinx = 0.3125

x = arcsin(0.3125)

x1 = 18.2

Since sin theta is positive in the second quadrant, x2 = 180 - 18.2 = 161.8°

Since our angle must lie in between  0° and 720°,then;

x3 = 360 + 18.2 = 378.2°

<em>Hence the required angles are 18.2°, 161.8° and 378.2°</em>

Using the probability concept, considering complementary probabilities, there is a 0.12 = 12% probability that the integer is of 20 or more.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

If two events are complementary, the <u>sum of their probabilities is of 1</u>. In this problem, we have that an integer being less than 20 is complementary to an integer being 20 or more.

We have that:

  • There is a 0.88 probability that the number is less than 20.
  • There is a x probability that the number is 20 or more.

These events are complementary, hence:

0.88 + x = 1

x = 1 - 0.88

x = 0.12

There is a 0.12 = 12% probability that the integer is of 20 or more.

How to answer this ?
inessss [21]

Answer:

Each term is separated by an addition or subtraction sign.

Coefficients are numbers in front of a variable (letter).

Constants are numbers with nothing else.
