If you roll a die 100 times, what is the approximate probability that you will roll between 9 and 16 ones, inclusive? (Round you
r answer to two decimal places.) HINT [See Example 4.]
1 answer:
Answer: 0.47
Step-by-step explanation:
Given that
n = 100, probability of rolling 1 = 1/6
binomial approximation
np = 100 ( 1/6) = 16.667
standard deviation = √ 100 × 1/6 ×5/6 = 3.7627
P ( 9 ≤ X ≤ 16 )
= P ( 8.5 < X < 16.5 )
so,
= P ((8.5 - 16.6667) / 3.7627 < Z < (16.5 - 16.6667) / 3.7627
= P ( -2.17 < Z < -0.04 )
= 0.484 - 0.015
= 0.47
Therefore the approximate probability that you will roll between 9 and 16 ones is 0.47

Answer: 8.33 times
Explanation:
P(4) = 1/6
P(4) for 50 times = 1/6 x 50 = 8.33 times
0.89, 1.009, 1.017, 1.02, 1.1 is the correct order
Answer:
2x - y = 13
Step-by-step explanation:
To write the equation of a line use the formula .
Substitute m = 2 and (4,-5).
Area (square)=side²
therefore:
side²=200 feet²
side=√(200 feet²)=14.142 feet≈14.1 feet.
solution: side of square=14.1 feet.
