Answer:

 -1

Step-by-step explanation:

Given: Mean= 25 minutes.

           Standard deviation= 2 minutes

           x= 23 minutes.

Lets find the z-score for the number of sandwiches delivered in less than 23 mins.

Formula: Z-score= \frac{x-mean}{standard\ deviation}

Z-score= \frac{23-25}{2}

⇒ Z-score= \frac{-2}{2}

∴ Z-score will be -1

Hence, -1 is the z-score for the number of sandwiches delivered in less than 23 minutes.

Find the quotient of n(x) = 6x^5y^7 and m(x) = 2x^3y
likoan [24]

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:

\frac{n(x)}{m(x)} =\frac{6\,x^5\,y^7}{2\,x^3\,y} =3\,x^2\,y^6

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.
