Step-by-step explanation:
here's your solution
==> perimeter of above figure = (30 + 13 + 13)*2
==> perimeter = 56*2
==> perimeter = 112 unit
==> now , we have to find area
==> firstly divide whole figure in two parts
==> and then divide each into three parts
==> area of rectangle = 30*5
==> area of rectangle = 150 unit^2
==> area of two traingle = (1/2)*2 12*5
==> area of two traingle = 30 unit^2
==> area of one part = 150 + 30 = 180 unit^2
now area of whole figure = 2*180
area = 360 unit^2
Answer:
0.66% probability that exactly 40 of the murders were Cleared.
Step-by-step explanation:
For each murder, there are only two possible outcomes. Either it was cleared, or it was not cleared. The probability of a murder being cleared is independent of other murders. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The 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 combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
64% of murders committed last year were cleared by arrest or exceptional means.
This means that
Fifty murders committed last year are randomly selected.
This means that
Find the probability that exactly 40 of the murders were Cleared.
This is P(X = 40).
0.66% probability that exactly 40 of the murders were Cleared.
Answer:
90°
Step-by-step explanation:
Since, all sides of the given quadrilateral are equal. Therefore it is rhombus.
Diagonals of a rhombus bisects at right angles.
So, x = 90°
