N = 20, the number of questions
p = 1/5 = 0.2, the probability of making a correct guess
q = 1 - p = 0.8, the probability of making an incorrect guess.
Expected success = 60% or 6 of 10.
From the binomial distribution,
P(6 of 10) = ₁₀C₆ p⁶q⁴
= 210*0.2⁶*0.8⁴ = 0.0055
Answer: 0.0055
Answer:
4673 mm²
Step-by-step explanation:
<u>Data</u>
iPhone's screen is a rectangle. The area of rectangle is calculated as base*height. Replacing with data we get:
Area of rectangle = area of the iPhone's screen = 51.7 mm * 90.39 mm = 4673.163 mm² ≈ 4673 mm²
<h3>
Answer: 375.9 sq ft</h3>
This is assuming there is no overlap.
===================================
Work Shown:
1 bag = 125.3 sq ft
3*(1 bag) = 3*(125.3 sq ft)
3 bags = 375.9 sq ft
Answer:
4.38, 4.397, 4.4 is the order from least to greatest.
