Answer:

Step-by-step explanation:

An way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

There is A Spinner That Have 8 Space 1-8 What Is The Probability That Te Spinner Will NOT Land On 5 or 8?

insens350 [35]

Answer:

$\frac{3}{4}$

Step-by-step explanation:

<u>Key skills needed: Probability, Possible Outcomes</u>

1) We are given a spinner --> With numbers: 1,2,3,4,5,6,7, and 8

That means there are 8 numbers on the spinner.

2) The problem asks what is the probability that the spinner will not land on 5 or the 8.

To calculate this --> $\frac{acceptedoutcomes}{total}$

3) The accepted outcomes are when the spinner lands on --> 1,2,3,4,6,7

That is 6 accepted outcomes.

4) The total outcomes is 8 (since there are numbers the spinner can land on).

5) Therefore, the answer would be $\frac{6}{8}$

$\frac{6}{8}$ can be simplified into $\frac{3}{4}$ as both the numerator (6) and the denominator (8) share a factor of 2.

6) With this --> $\frac{3}{4}$ is the answer.

Ganezh [65]

Answer:

smallest number=3

Step-by-step explanation:

let the numbers be x & y and x>y

x-y=5

multiply by 2

2x-2y=10

and 3x+2y=30

adding

5x=40

x=40/5=8

8-y=5

y=8-5=3

Convert these unlike fractions to equivalent like fractions and add them. You must use the lcd to get the answer correct. If pos

ra1l [238]

Unlike fraction 1/7 is converted to equivalent like fraction 2/14 and the sum of 2/14 + 3/14 = 5/14.

As given in the question,

Given fraction is equal to:

1/7=? + 3/14=?

Here there are two fractions

1/7 and 3/14

LCD( least common denominator) of 7 and 14 is equal to 14.

Now make them like fractions

1/7 is equivalent to

( 1/7) × ( 2/2) = 2/ 14

Now 2/14 and 3/14 are like fractions

Sum of like fractions is:

2/14 + 3/14

= ( 2+ 3) / 14

= 5/ 14

Therefore, the conversion of unlike fraction 1/7 to like fraction is 2/14. And sum of 2/14 + 3/14 = 5/14.

The complete question is:

Convert these unlike fractions to equivalent like fractions and add them. You must use the LCD to get the answer correct. If possible, reduce the final sum. 1/7=? + 3/14=?
