A biased coin has a probability of 0.4 of coming up heads. What is the probability that when flipped one hundred times it comes up heads half of the trials or more. Give answer to at least three decimal points.
Answers
Using the binomial probability relation ; the probability that an head is obtained at least 50 times is 0.0271
Using the binomial probability relation :
P(x = x) = nCx * p^x * q^(n-x) p = probability of success = 0.4q = 1 - p = 0.6n = number of trials = 100P(x ≥ 50) = p(x = 50) + p(x = 51) + ...+ p(x = 100)
Using a binomial probability calculator :
P(x ≥ 100) = 0.0271
Therefore, the probability that atleast 50 heads are obtained in the trial is 0.0271

At the grocery store, 6 pints of ice cream cost $12.54. How much would 40 pints of ice cream cost?
Answers
Answer:
$83.60
Step-by-step explanation:
to find the answer you need to know the price of one pint (unit rate) so we divide 12.54 by 6.
12.54 ÷ 6 = 2.09

draw a square and its diagonals how many angles are formed by the intersection of the diagonals?
Answers
A square has 2 diagnals. imagine 2 lines connecting every opposite angle of the square. that leaves 2 intersecting lines. Sinse the two lines are intersecting, they form angles. Because there are only 2 lines, there are 4 angles. The answer is 4.
A square is a four-equal-sided figure with the diagonals of the square cut perpendicular to each other as shown below and the number of angles formed by diagonals is 4.
What is a square?A square is a geometrical figure in which we have four sides each side must be equal and the angle between two adjacent sides must be 90 degrees.
Area of square = Side²
The perimeter of the square = 4× side
A square is a geometrical figure in which we have four sides each side must be equal and the angle between two adjacent sides must be 90 degrees.
There are two diagonals in every square.
The angle of intersection between both diagonals is 90 degrees.
