Answer:
x=1+i√19,1-i√19
Step-by-step explanation:
Write the problem as a mathematical expression.
Subtract from both sides of the equation.
Use the quadratic formula to find the solutions.
Substitute the values, and into the quadratic formula and Simplify.
Simplify the numerator. Multiply by Simplify
If you multiply $8.00 by 6.35% the answer is .508. Round that up to .51. So tax is .51. You add that to $8.00 for a total amount of $8.51.
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:
18
Step-by-step explanation:
Mode = modal class (Recurring)
The number/value that appears the most which in this case is 18 because it can be seen twice.
