5x + 12 + 3x = 6(x + 4)<br><br> Please Show Work.
Len [333]

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

Which statement is true about the ranges for the box plots?
11111nata11111 [884]

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.

Which answer is the approximate standard deviation of the data set?
Ierofanga [76]

Answer:  A. 6.5

Step-by-step explanation:

Here, the given set = { 15, 19 3, 12, 17, 2, 2, 8}

Mean, \overline{ x} = \frac{15+19+3+12+17+2+2+8}{8} = \frac{78}{8} = 9.75

Number of elements, n = 8

\frac{\sum (|x-\overline{x}|)^2}{n}=42.4375

Thus, the standard deviation, \sigma =\frac{\sqrt{\sum(|x-\overline{x}|)^2} }{n}=\sqrt{\frac{339.5}{8}}=\sqrt{42.4375} = 6.51440711\approx 6.5

⇒ Option A is correct.
