Answer:
6.98%
Step-by-step explanation:
To find relative frequency we divide frequency with the total number participants in that age bracket
Total number of participants age 10-19=172.....................given in the table
The frequence for those who ski at age 10-19=12---------------given in table
Relative frequency= 12/172 = 0.0697
Expressed as a percentage= 0.06976×100 =6.98%
We have to calculate the area of the rhombus if AE = 20 m and DE = 32 m.The diagonals DB = 2 * DE and AC = 2 * AE.
DB = 2 * 32 = 64 mAC = 2 * 20 = 40 mArea = d1 * d2 / 2 = DB * AC / 2 = 64 * 40 / 2 = 1,280 m²Answer: The area of the rhombus is B ) 1,280 m².

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
1/2(8x - 4) = 2x
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Distributive Property] Distribute 1/2: 4x - 2 = 2x
- [Subtraction Property of Equality] Subtract 2x on both sides: 2x - 2 = 0
- [Addition Property of Equality] Add 2 on both sides: 2x = 2
- [Division Property of Equality] Divide 2 on both sides: x = 1
Answer:
Step-by-step explanation:
So we have the equation:
First, subtract 9 from both sides:
Divide both sides by -4:
Definition of Absolute Value:
Subtract 3 from both sides:
Divide both sides by 5:
And we're done!
