Answer:
99
Step-by-step explanation:
P(3) = 1-0.88 = 0.12
P(3 or 4) = 0.12 + 0.21 = 0.33
Expected no. = no
= 300(0.33) = 99

ANSWER
The value of x is,

EXPLANATION
We were given that the opposite angles of a parallelogram are

and

.
The opposite angles of a parallelogram are equal.
We can write the equation below in x and use to find the value of x.

We group like terms to obtain,

This implies that,

We divide both sides of the equation by 2 to obtain,
Answer: fg
and
Domain: All real number. All real number or 
Explanation:
fg means product of two given function f(x) and g(x)
where,
and 
Now, we have to find fg
So, fg=
Substitute f(x) and f(x)

Using distributive property simplify above expression and we get,

We can see it is cubic polynomial. So, domain of cubic polynomial is all real number.
Domain: All real number or 
A. f(x) = 0.75xb. g(x) = x - 5c. $88.75d. Yes, if you do f(x) before g(x) or g(x) before f(x), you get different final prices.
