Answer:
Second one
Step-by-step explanation:
Answer:
B) 15.85%
Step-by-step explanation:
normalcdf(minimum,maximum,μ,σ)
normalcdf(39,189,264,75)
≈0.1573
≈15.73%
Therefore, the closest answer is B
The y intercept and the gradient
(6y - 11)(6y + 11) = ay
² - b |use (a - b)(a + b) = a² - b²
(6y)² - 11² =ay² - b
36y² - 121 = ay² - b |add b to both sides
ay² = 36y² - 121 + b |divide both sides by y² ≠ 0
a = (36y² - 121 + b)/y²
There as 16 cards, 2 of which are wildlife cards, so the ratio is 16 : 2. We can simplify it by dividing both sides by 2, so we'll get the ratio of 8 : 1.
I hope this helps! :)
