Answer:
The area of the triangle is 48.6 square inches.
Step-by-step explanation:
The area of a triangle ABC is given by
a = 7.5 inches
b = 13 inches
C = 94 °
Plugging these values in the above formula to find the area of the triangle
On simplifying, we get
Rounded to the nearest tenth
The area of the triangle is 48.6 square inches.

Answer:
The mean, variance, and standard deviation of the binomial distribution are 10, 8, and 2.83 respectively.
Step-by-step explanation:
We have to find the mean, variance, and standard deviation of the binomial distribution with the given values of n and p, i.e; n = 50 p = 0.2.
Let X = <u><em>binomial random variable</em></u>
So, X ~ Binom(n = 50, p = 0.2)
Now, the mean of the binomial distribution is given by;
Mean of X, E(X) = n p
= 50 0.2 = 10
Now, the variance of the binomial distribution is given by;
Variance of X, V(X) = n p
(1 - p)
= 50 0.2
(1 - 0.2)
= 10 0.8 = 8
Also, the standard deviation of the binomial distribution is given by;
Standard deviation of X, S.D.(X) =
=
= = 2.83
