Answer:
Probability is 0.3506
Step-by-step explanation:
We are given
mean is 8mm
so,
standard deviation is 2.2 mm
so,
x-varies from 7mm to 9mm
At x=7:
we can use formula
we can plug values
At x=9:
we can use formula
we can plug values
So, z is between -0.45455 and 0.45455
now, we can use normal distribution table
and we get
Probability is 0.3506
Answer:
a. Yes
b. Yes
c. Yes
d. Degree 8
Step-by-step explanation:
a. Yes, n(x) is a polynomial of one single term (also called monomial) because it contains variables raised to positive integers.
b. Yes, m(x) is a polynomial of also one single term (also called monomial) because it contains variables raised to positive integers.
c. The quotient of n(x) / m(x) can be reduced to a polynomial of one single term as follows:
which as can be seen, also contains variables raised to positive integers.
d. The degree of the polynomial resultant is the addition of the powers of all variables present (x and y) which results in: 2 + 6 = 8
Therefore the degree of this polynomial is 8.
