Answer:

These are called supplementary angles.

Step-by-step explanation:

Supplementary angles are equal to 180 degrees. 100 + 80 is equal to 180 degrees, meaning that the angles are supplementary. I hope this helps! :)

Supplementary, they are always equal to 180 and can also be described as a straight line

Amelie has a spinner divided into ninths equal sections that are labeled 1 through 9. she wants to compare the theoretical proba

VMariaS [17]

The theoretical probability = $\dfrac{5}{9}$ , The experimental probability = $\dfrac{5}{12}$

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

The experimental probability of an event occurring is the number of times that it occurred when the experiment was conducted as a fraction of the total number of times the experiment was conducted.

The sample will be ={1,2,3,4,5,6,7,8,9}=9

favourable outcomes={1,3,5,7,9,}=5

The theoretical probability of spinning and odd number = $\dfrac{5}{9}$

As she spends the spinner 12 times

The experimental probability = $\dfrac{5}{12}$

Hence the theoretical probability = $\dfrac{5}{9}$ , The experimental probability = $\dfrac{5}{12}$

The tickets in a box are numbered from 1-20 inclusive. If a ticket is chosen at random and replaced, and then a second ticket is

victus00 [196]

1) The sum of the two numbers is even either the two numbers are even or the two numbers are odd.

2) The probability that the two numbers are even is the product of the probabilities for each event:

- Probability that the first number is even: 10 / 20 = 0.5

- Probability that the second number is even: 10 / 20 = 0.5

- Probability that the two numbers are even: 0.5*0.5 = 0.25

3) The probability that the two numbers are odd is the product of the probabilities for each event:

- Probability that the first number is 0dd: 10/20 = 0.5

- Probability that the second number is odd: 10/20 = 0.5

- Probability that both numbers is odd = 0.5*0.5 = 0.25

4) Probability tha the sum is eve: 0.25 + 0.25 = 0.5

Answer: 0.5.

And it is reasonable, half of times the sum is even and half the sum is odd.

If tatianna works 3hrs a day on school days and make $123.75 a week what is her hourly rate?

madreJ [45]

Answer:

Her hourly rate is $8.25

Explanation:

Tatianna works 3 hours a day on school days and makes a total of $123.75 in a week

We know that:

There are 5 school days in a week

We are given that:

She works for 3 hours a day each of those days

Therefore:

Total number of hours worked = hours worked daily * number of days

Total number of hours worked = 3 * 5 = 15 hours in a week

The equation used to calculate Tatianna's earnings is:

Amount she makes in a week = Total number of hours worked * hourly rate

Now, we substitute with the givens to get the hourly rate as follows:

Amount she makes in a week = Total number of hours worked * hourly rate

123.75 = 15 * hourly rate

Hourly rate = $8.25
