Answer:
$17
Step-by-step explanation:
You need to find 20 percent. so find 10 percent or divide by ten then multiply that by two
x-intercept(s): (1/2, 0) or (0.5, 0)
y-intercept(s): (0, −2)
Answer:1. 4x^2-3x-6
2. 4x^2+7x-8
3. Is the same problem as #2
Step-by-step explanation:
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
Hope this Helps!!!
