Answer:
A = 55.63 cm^2
Step-by-step explanation:
Let a,b,c be the lengths of the sides of a triangle. Heron's formula states that:
Area = √(p (p−a) (p−b) (p−c))
where p is half the perimeter, or
(a+b+c) / 2
So lets start by finding p:
(10.6 + 10.6 + 16) / 2
p = 18.6
Now lets substitute p and the other values into our equation:
A = √ (18.6 (18.6−10.6) (18.6−10.6) (18.6−16))
So let's plug this in to our calculators
A = √ (3095.04)
A = 55.633083682284 cm^2
Answer:
1820
Step-by-step explanation:
X the size of the club will follow negative binomial distribution with probability of success p and number of failures r
p = 364/365, r = 5
hence E[x] = pr/(1-p) = 364/365 x 5 /(1/365) = 1820
The two events that are disjoint or mutually exclusive is getting a head and a tail at the same time. It because if you are going to flip a coin the result can either be head or tail but not both. The value of the two events occurring at the same is 0.
i think that you would just take 23/4=$5.75
so take 6 times 5.75 and you should get $34.5
