General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
-4 - (z - 6) = 12
<u>Step 2: Solve for </u><em><u>z</u></em>
- Distribute negative: -4 - z + 6 = 12
- Combine like terms: -z + 2 = 12
- Subtract 2 on both sides: -z = 10
- Divide -1 on both sides: z = -10
<u>Step 3: Check</u>
<em>Plug in z to verify it's a solution.</em>
- Substitute: -4 - (-10 - 6) = 12
- Subtract: -4 - (-16) = 12
- Simplify: -4 + 16 = 12
- Add: 12 = 12
Here we see that 12 does indeed equal 12.
∴ z = -10 is a solution of the equation.
Answer is 127 mm :)
because it's 12.7 cm,
so 127 mm
Answer:
1/2
Step-by-step explanation:
Please find attached the diagram used in answering this question
A box plot is used to study the distribution and level of a set of scores
the scores are distributed into 4 groups. Each group has a value of 25%
the box plot consists of two lines and a box. the two lines are known as whiskers. the whiskers represent scores outside the middle 50%
On the box, the first line to the left represents the lower quartile. 25% of the score represents the lower quartile
the next line on the box represents the median. 50% of the score represents the median
The third line on the box represents the upper quartile. 75% of the scores represents the upper quartile
In this question, 68 is on the second line which represents the median. Thus 1/2 of the height are at least 68 inches
