Determine the number of outcomes in the event. Decide whether the event is a simple event or not.

Anna35 [415]

Answer:

<u>No</u>, The event B is not a simple event because event B has <u>more than one</u> outcome.

Step-by-step explanation:

Consider the provided information.

A computer is used to select randomly a number between 1 and 9 comma inclusive.

Event B is selecting a number greater than 4.

Let B be an event that the selected number greater than 4.

We have given that the total number used by the computer is:

1, 2, 3, 4, 5, 6, 7, 8, 9

Now the sample space for selecting a number greater than 4 is:

S = {5, 6, 7, 8, 9}

Therefore, the event B has 5 outcomes.

The event B is not a simple event because event B has more than one outcome.

Simplify. 4−16÷4+4^2

Romashka [77]

Remember to follow PEMDAS. (Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction)

4^2 = 4 x 4 = 16

16/4 = 4

4 - 4 + 16

Combine

4 - 4 = 0 + 16 = 16

16 is your answer

The missing angles in the triangle is as follows:

∠1 = 62.5°
∠2 = 62.5°
∠3 = 55°
∠4 = 75°
∠5 = 50°

<h3>How to find the measure of angles in a triangle?</h3>

A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.

∠3 = 55 degrees (vertically opposite angles)

Vertically opposite angles are congruent to each other.

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.

Using exterior angle theorem ,

105 = ∠5 + 55

∠5 = 105 - 55

∠5 = 50 degrees

∠4 = 180 - 50 - 55

∠4 = 75 degrees

Therefore, the other triangle is an isosceles triangle. This means the base angles are equal.

Hence,

∠1 = ∠2 = x

2x + 55 = 180

2x = 180 - 55

2x = 125

x = 125 / 2

x = 62.5 degrees.

Hence,

∠1 = ∠2 = 62.5 degrees.

4. A plane's average speed between two cities is 200 m/s. If the trip takes 2.5 hours, how far does the plane fly?

ioda

Step-by-step explanation:

Average speed (S) = 200 m/s

Time taken (t) = 2 .5 hours = 2.5 *60*60 = 9000 sec

Now distance travelled (d) = ?

We know

The distance travelled by a body per unit time is

speed so

S = d / t

200 = d / 9000

d = 9000 * 200

d = 1800000 meters.

The plane flies 1800000 meters.
