Step-by-step explanation:
7a-3a
5b+4b
Step-by-step explanation:
- 6x-2=8x+11
- 6x-8x=11+2
- -2x=13
- x=13/-2
- x=-6.5
Answer: n3 when
Step-by-step explanation: just say he fell in the water
Answer:
B.
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define function</u>
f(x) = 8x + 4
<u>Step 2: Prep</u>
- Rewrite: y = 8x + 4
- Swap <em>x</em> and <em>y</em>: x = 8y + 4
<u>Step 3: Find Inverse (Solve for </u><em><u>y</u></em><u>)</u>
- Subtract 4 on both sides: x - 4 = 8y
- Divide both sides by 8: (x - 4)/8 = y
- Rewrite: y = (x - 4)/8
- Rewrite: f⁻¹(x) = (x - 4)/8
Measures of variation: <span> ways to describe measures of central tendency for a data.
<em>
</em><em>the most common measure of variation is range, so in this case, the smallest number is 1, and the largest is 17. This means the range is 16.
</em>
Interquartile Range:
<em>Lower q: {1, 2, 4}
</em><em>Upper q: {8, 12, 17}
</em>Here you have to subtract 12 from 2, which gives you 10.
Mean absolute deviation:
Alright, let's first find the mean...
(1+2+4+5+8+12+17)
---------------------------= 7
7
What is the distance of each number from 7?
1: 6 units
2: 5 units
4: 3 units
5: 2 units
8: 1 unit
12: 5 units
17: 10 units
After adding all of these together, and dividing by 7, you will get...
<em>4.571428 </em></span>≈ <em>4.6 or 5.
