Answer:
<u>The range of the given data set is 23.</u>
Step-by-step explanation:
Let's recall that the range of a data set it’s the difference between the highest value and the lowest value.
Step 1:
Let's identify the highest value : 34
Let's identify the lowest value: 11
Step 2:
Let's subtract the smallest number in the set from the largest number in the set:
34 – 11 = 23
<u>The range of the given data set is 23.</u>
Answer:
x = -84, y = -58
Step-by-step explanation:
2x - 3y = 6 --- Equation 1
Equation 1×5: <em>10x</em> - 15y = 30 --- Equation 2
5x + 7y = -14 --- Equation 3
Equation 3×2: <em>10x</em> + 14y = -28 --- Equation 4
<u>I will eliminate 10x. </u>
Equation 4-2:
10x - 15y - 10x + 14y = 30-(-28)
-y = 30+28
= 58
y = -58
Substitute y =-58 into Equation 1.
2x - 3y = 6
2x - 3(-58) = 6
2x - (-174) = 6
2x + 174 = 6
Find 2x.
2x = 6-174
= -168
Find x.
x = -168 ÷ 2
x = -84
