Answer:
Option C is correct.
f = 2
Step-by-step explanation:
The mean is the sum of variables divided by the number of variables
Mean = (Σfx)/(Σf)
xi | 15 | 17 | 20 | 30 | 10 + f
fi | 4 | 4 | 6 | 5 | 6
Σfx = (15×4) + (17×4) + (20×6) + (30×5) + [(10+f)×6] = 60 + 68 + 120 + 150 + 60 + 6f = (458 + 6f)
Σf = 4 + 4 + 6 + 5 + 6 = 25
Mean = 18.8
18.8 = (458+6f) ÷ 25
458 + 6f = 25 × 18.8 = 470
6f = 470 - 458 = 12
f = (12/6) = 2

Answer:
y = -6x + 20
Step-by-step explanation:
Answer:
<em>The correct answer is </em><u><em>(-B-)</em></u>
Step-by-step explanation:
<em>Why this would be (B), A normal size shape triangle is a right angle and that would mean the L=Length, = </em><u><em>5</em></u><em>, H=Height=</em><u><em>6</em></u><em>, B=Base, = </em><u><em>5</em></u><em>. </em>
You can take 5 and 10 to turn that into 15 and + 6 = 21 x bh = 40
