Artyom0805 [142]3 years ago
3 0

Answer:

x = 29

Step-by-step explanation:

We know that those two angles equal 180° so we combine those two equations and set them equal to 180°:

6x + 6 = 180°

Subtract 6 from both sides:

6x = 174°

Divide by 6:

x = 29

Use synthetic substitution to evaluate the polynomial P(x) = x^3-3x^2+4x-7 for x=3
Zina [86]

Answer:

\frac{x^3-3x^2+4x-7}{x-3} =(x^2+4)+\frac{5}{x-3}

Step-by-step explanation:

We are given polynomial as

P(x)=x^3-3x^2+4x-7

and it is divided by x=3 or x-3

we can use synthetic division

so, we got

Remainder =5

Quotient is

=x^2+0x+4

=x^2+4

we can write as

\frac{x^3-3x^2+4x-7}{x-3} =(x^2+4)+\frac{5}{x-3}

Determine whether the quantitative variable is discrete or continuous. Depth of the ocean floor Is the variable discrete or cont
Vesna [10]

Answer:

B. The variable is continuous because it is not countable.

Correct, from the definition about of continuous data we see that is a random variable is continuous then it can't be countable.

Step-by-step explanation:

Previous concepts

A discrete random variable "has a countable number of possible values" in a domain defined. So then the possible values for these types of random variables are the integers.

A continuous is a random variable "where the data can take infinitely many values" that means that can take values from the rational with decimals. Ans is not countable.

Solution to the problem

Let's analyze one by one the possible options:

A. The variable is discrete because it is countable.

False, the depth of the ocean is a continuous random variable since we can have for exampe a depth of 1200.56 mi and we can't express this as a discrete random variable.

B. The variable is continuous because it is not countable.

Correct, from the definition about of continuous data we see that is a random variable is continuous then it can't be countable.

C. The variable is discrete because it is not countable.

False, the depth of the ocean is a continuous random variable since we can have for exampe a depth of 504.67 Km and we can't express this as a discrete random variable.

D. The variable is continuous because it is countable.

False the variable is continuous but cannot be countable since that's the opposite from the definition of continuous random variable.

PLEASE PLEASE I NEED HELP
Leya [2.2K]

Answer:

No there is not

Step-by-step explanation:

Combine like terms so 3x+2x= 5x so it would leave you with 5x+2  In the problems there is a 5x in both and a 2 in one and a 5 in the other so they could not be possible to solve because what ever you do 5x+5 will always be 3 more then the other.
