Answer:

(D) 20

Step-by-step explanation:

We are given the data as the scores, these are:

83, 77, 88, 93, 97, 79, 94, 80, 97, 81

In order to find the range, firstly arrange the data in ascending order, we have

77, 79, 80, 81, 83, 88, 93, 94, 97, 97

Now, the range of the given data is equals to highest data point- lowest data point, thus

R=97-77

R=20

Therefore, the range of the given data set is 20.

Hence, option (D) is correct.

State whether the equation is true, false or open? 4y+8=6y+3
g100num [7]

<u><em>Answer:</em></u>

Open


<u><em>Explanation:</em></u>

An open equation is an equation that has variables and CAN be solved

<u>Example</u>: 2x = 4 ......> can be solved giving ......> x = 2

A false equation is one where both sides can NEVER be equal

<u>Example:</u> 15 = 2(3) + 1 ..........> 15 can never be equal to 7

A true equation is one having no variables and both sides are ALWAYS equal

<u>Example:</u> 2(3) + 1 = 2(2) + 3 ........> 7 will always be equal to 7


Now, the given equation is:

4y + 8 = 6y + 3

Let's try to solve is:

4y + 8 = 6y + 3

6y - 4y = 8 - 3

2y = 5

y = 2.5


Therefore, the given equation contains a variable and can be solved which means that it is an open equation


Hope this helps :)
