the measure of the supplement angle is 24 more than three time the measure of the original angle. find the measures of the angle
Gala2k [10]

Step-by-step explanation:

Let x° be the original angle. Then the supplement angle is (180 - x)° and (180 - x) = 3x + 24.

180 - x = 3x + 24

4x = 156

x = 39

Hence the original angle is 39° and the supplementary angle is 141°.

Describe a relationship modeled by the function f(x) = 4x3 − 72x2 + 320x
solmaris [256]

Answer:

  • A relationship modeled by the function f(x) = 4x³ - 72x² + 320x is the volume of a right prism whose dimensions are 4 times a desired length, 10 units less that such desired length, and 8 units less than the same desired length.

Explanation:

To find a relationship modeled by the given function it is recommendable to factor it.

The function is:

  • f(x)=4x^3-72x^2+320x

The first step to factor it is to extract common factor 4x:

  • f(x)=4x(x^2-18x+80)

The second step is to factor the quadratic trinomial.

That is made by writting it as a product of two binomials, for which the two constant terms add up - 18 and their product is 80. Those terms are -10 and - 8; so the two factors are (x - 10) and (x - 8), and the factored form is:

  • f(x)=(4x)(x-10)(x-8)

Then, a relationship modeled by that polynomial is the volume of right prism whose dimensions are 4 times a desired length, 10 units less that such desired length, and 8 units less than the same desired length.

  • x is the desired (unknown) length
  • 4x is 4 times the desired length
  • x - 10 is 10 less than the desired length
  • x - 8 is 8 less than the desired length

Thus, the volume of the prism is the product of the three factors:

  • Volume = (4x)(x-10)(x-8)

Answer:

No, the sum of all the probabilities is not equal to 1.

Step-by-step explanation:

Given

\begin{array}{ccccc}x & {0} & {1} & {2} & {3} & {P(x)} & {0.001} & {0.007} & {0.033} & {0.059}  \ \end{array}

Required

Determine if the given parameter is a probability distribution

For a probability distribution to exist, the following must be true;

\sum P(x)=1

So, we have:

\sum P(x) = 0.001 + 0.007 + 0.033 + 0.059

\sum P(x) = 0.1

<em>Hence, it is not a probability distribution because the sum of all probabilities is not 1</em>
