The length of playing field is 58.9 feet
<u>Solution:</u>
Given that, the diagonal length of a rectangular playing field is 76 feet,
And its width is 48 feet.
<em><u>To find: length of playing field</u></em>
Now, we know that, <em>diagonal, width and length of a rectangle will form an right angle triangle with diagonal as hypotenuse. </em>
So, now, in a right angled triangle we can use pythagorean theorem to find the length
Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.
By above definition, In a right angled triangle ABC we get
Where "c" is the length of hypotenuse
"a" is the length of one leg of right angled triangle
"b" is the length of other leg of right angled triangle
Hence, the length of the rectangular field is 58.9 feet
Answer:
a) P(X = 0) = 0.5997
b) P(X = 9) = 0.0016
c) P(X = 8) = 0.0047
d) P(X = 5) = 0.4018
Step-by-step explanation:
These following problem are examples of the binomial probability distribution.
Binomial probability
Th binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinatios of x objects from a set of n elements, given by the following formula.
And is the probability of X happening.
(a) for n = 4 and π = 0.12, what is P(X = 0)?
(b) for n = 10 and π = 0.40, what is P(X = 9)?
(c) for n = 10 and π = 0.50, what is P(X = 8)?
(d) for n = 6 and π = 0.83, what is P(X = 5)?
