Keywords:

<em>Number, multiplied, equation, variable </em>

For this case we are asked to find a number that when multiplied by "9" of result "35", then we propose an equation with a variable, in which we must find the value of said variable, which represents the number that must be multiplied for 9.

We have to:

x: Represents the number multiplied by "9"

So:

x * 9 = 35

We must clear the variable "x", for it we divide between "9" on both sides of the equation:

\frac {9x} {9} = \frac {35} {9}\\x = \frac {35} {9}\\x = 3.888888889

If we round with two decimals:

x = 3.89

Thus, the number that is multiplied by 9, to obtain 35 is x = 3.888888889

Answer:

x = 3.888888889

The times of the runners in a marathon are normally distributed, with a mean of 3 hours and 50 minutes and a standard deviation
balu736 [363]

Answer: 0.16

Step-by-step explanation:

Given that the run times provided are normally distributed ;

Mean(x) of distribution = 3 hours 50 minutes

Standard deviation(s) = 30 minutes

The probability that a randomly selected runner has a time less than or equal to 3 hours 20 minutes

3 hours 20 minutes = (3 hrs 50 mins - 30 mins):

This is equivalent to :

[mean(x) - 1 standard deviation]

z 1 standard deviation within the mean = 0.84

z, 1 standard deviation outside the mean equals:

P(1 - z value , 1standard deviation within the mean)

1 - 0.8413 = 0.1587

= 0.16

SOLUTION

TO DETERMINE

The degree of the polynomial

CONCEPT TO BE IMPLEMENTED

POLYNOMIAL

Polynomial is a mathematical expression consisting of variables, constants that can be combined using mathematical operations addition, subtraction, multiplication and whole number exponentiation of variables

DEGREE OF A POLYNOMIAL

Degree of a polynomial is defined as the highest power of its variable that appears with nonzero coefficient

When a polynomial has more than one variable, we need to find the degree by adding the exponents of each variable in each term.

EVALUATION

Here the given polynomial is

In the above polynomial variable is z

The highest power of its variable ( z ) that appears with nonzero coefficient is 5

Hence the degree of the polynomial is 5

FINAL ANSWER

The degree of the polynomial is 5
