(16 + 15 -10 +4) = 25
25 squared is 625
Answer:
0.2047
0.2377
Step-by-step explanation:
1.
What we have here is a binomial distribution
Probability p = 0.12
N = number of students in the class = 30
Probability of finding 4 left handers
P(x = 4) = 30C4 x (0.12)⁴ x (0.88)²⁶
= 27405 x 0.00020736 x 0.03602047835
= 0.2047
2.
This is also a binomial distribution
N = 10 p = 0.65
P(of 6 knowledgeable fans)
= 10C6 x (0.65)⁶ x (0.35)⁴
= 210 x 0.0754189 x 0.01500625
= 0.2377
Well it depends...... (.5= 1/2)
Answer:
x² + 6
Step-by-step explanation:
Given
(4x² - 6x + 8) - (3x² - 6x + 2) ← distribute by - 1
= 4x² - 6x + 8 - 3x² + 6x - 2 ← collect like terms
= x² + 6
Answer:
$12.49
Step-by-step explanation:
The price right now = 0.8 * the original price
9.99 = 0.8*x
x=12.4875
x≈12.49
Sorry, I thought your problem meant that it was 20% the original price, not 20% off.
