5x + 12 + 3x = 6(x + 4)
5x+3x+12=6(x+4)
Multiply the bracket by 6
(6)(x)(6)(+4)=6x+24
5x+3x+12=6x+24
8x+12=6x+24
Move 6x to the other side. Sign changes from +6x to -6x.
8x-6x+12=6x-6x+24
8x-6x+12=24
2x+12=24
Move 12 to the other side. Sign changes from +12 to -12.
2x+12-12=24-12
2x=12
Divide by 2 for both sides.
2x/2=12/2
x=6
Answer: x=6
Answer:
A
Step-by-step explanation:
Range of a box plot is the highest value minus the lowest value.
<u>The picture attached shows which one is the highest value and which one is the lowest value.</u>
From our understanding and given graphs:
- The first Box Plot's Highest Value is 15 and Lowest Value is 3.
Range = Highest - Lowest = 15 - 3 = 12
- The second Box Plot's Highest Value is 16 and Lowest Value is 4.
Range = Highest - Lowest = 16 - 4 = 12
<u>Thus, the range of both the box plots are same</u>. Answer choice A is right.
Answer: A. 6.5
Step-by-step explanation:
Here, the given set = { 15, 19 3, 12, 17, 2, 2, 8}
Mean, 
Number of elements, n = 8

Thus, the standard deviation, 
⇒ Option A is correct.
F(5) = 2(5)^2 - 10
f(5) = 2(25) - 10
f(5) = 50 - 10
f(5) = 40
