Answer:
B and C option is the answer to this question
Step-by-step explanation:
Sample space of two fair fifty sided dice = 50^2 = 2500
Probability of rolling a double = 50/2500 = 1/50
Probability of not rolling a double = 1 - 1/50 = 49/50
Answer:
Step-by-step explanation:
Suppose that the side length is s. Imagine that one side is level. Draw a vertical line through the top vertex perpendicular to the base (level side). Label this vertical line "h." Then h and s are related as follows:
√3 h
sin 60 degrees = ------- = --------
2 s
s√3
and so h = the height of the triangle = -----------
2
The area of this triangle is (1/2)(base)(height), which here is:
(1/2)(s/2)( s√3 /2), or
(s^2)√3
A = ---------------
8
Answer:
So the answer is going to be B. AKA 22.5

Using it's formula, it is found that the standard deviation of the data-set is of 8.9.
<h3>How the standard deviation of a data-set is found?</h3>
- The standard deviation of a data-set is given by the <u>square root of the sum of the differences squared between each observation and the mean, divided by the number of values</u>.
- The mean of a data-set is given by the <u>sum of all values in the data-set, divided by the number of values</u>.
In this problem, the data-set is: {6, 7, 5, 22, 26}.
The mean is:
Hence, the <em>standard deviation</em> is:
