You are permitted to use your calculator to solve an equation, find the derivative of a function at a point, or calculate the value of a definite integral. However, you must clearly indicate the setup of your question, namely the equation, function, or integral you are using. If you use other built-in features or programs, you must show the mathematical steps necessary to produce your results. Your work must be expressed in standard mathematical notation rather than calculator syntax.

Show all of your work, even though the question may not explicitly remind you to do so. Clearly label any functions, graphs, tables, or other objects that you use. Justifications require that you give mathematical reasons, and that you verify the needed conditions under which relevant theorems, properties, definitions, or tests are applied. Your work will be scored on the correctness and completeness of your methods as well as your answers. Answers without supporting work will usually not receive credit. Unless otherwise specified, answers (numeric or algebraic) need not be simplified. If your answer is given as a decimal approximation, it should be correct to three places after the decimal point.

Answers

Answer is 8g^15
Pls mark me brainliest

Answer:

Your answer should be 8g^15

Step-by-step explanation:

If cubed (power of 3) is on a parenthesis, that means you have to cube every expression inside that parenthesis. In order to distribute exponents, mutliply them. This gives you g^5 times ^3, which is g^15. ^3 has to also be distributed to the 2, which is 2^3 = 8. 8 and g^15 is 8g^15.

What is the probabiWhich value cannot represent the probability of an event occurring?
StartFraction 1 over 100 EndFraction

Three-halflity of an event that is certain?

Answers

Given problem:

   Which value cannot represent the probability of an event occurring?

      Values:

            [tex]\frac{1}{100}[/tex]    0.29    [tex]\frac{85}{100}[/tex]   Three-halflity

Probability is the likelihood of an event to occur.

For an event that we are sure of occurring, the probability value is 1, and those that cannot occur have a probability value of 0.

  The probability of any event is usually a fraction between 1 and 0.

So we can see that the odd one is the  Three-halflity which is clearly greater than 1.

A resident of Bayport claims to the City Council that the proportion of Westside residents
(1) with income below the poverty level is lower than the proportion of Eastside residents
(2) The City Council decides to test this claim by collecting a random sample of resident incomes from the Westside of town and a random sample of resident incomes from the Eastside of town. Seventy-six out of 578 Westside residents had an income below the poverty level. Hundred-and-twelve out of 688 Eastside residents had an income below the poverty Specify the hypotheses.
Calculate the value of the test statistic (round to 4 decimal places).
Calculate the p-value (round to 4 decimal places).

Answers

Answer:

The test statistics is  [tex]z =  -1.56 [/tex]  

The p-value is   [tex]p-value =  0.05938 [/tex]

Step-by-step explanation:

From the question we are told  

   The West side sample  size is [tex]n_1  =  578[/tex]

    The  number of residents on the West side with income below poverty level is [tex]k  = 76[/tex]

    The East side sample size  [tex]n_2=688[/tex]

  The  number of residents on the East side with income below poverty level is [tex]u  = 112[/tex]

   The null hypothesis is  [tex]H_o  :  p_1 = p_2[/tex]

    The alternative hypothesis is  [tex]H_a :  p_1 <  p_2[/tex]

Generally the sample proportion of  West side is  

     [tex]\^{p} _1 = \frac{k}{n_1}[/tex]

=>   [tex]\^{p} _1 = \frac{76}{578}[/tex]

=>   [tex]\^{p} _1 =  0.1315 [/tex]

Generally the sample proportion of  West side is  

     [tex]\^{p} _2 = \frac{u}{n_2}[/tex]

=>   [tex]\^{p} _2 = \frac{112}{688}[/tex]

=>   [tex]\^{p} _2 =  0.1628 [/tex]

 Generally the pooled sample proportion is mathematically represented as

    [tex]p = \frac{k + u}{ n_1 + n_2 }[/tex]

=>  [tex]p = \frac{76 + 112}{ 578 + 688 }[/tex]

=>  [tex]p =0.1485[/tex]

Generally the test statistics is mathematically represented as

[tex]z = \frac{\^ {p}_1 - \^{p}_2}{\sqrt{p(1- p) [\frac{1}{n_1 } + \frac{1}{n_2}  ]}  }[/tex]

=> [tex]z = \frac{ 0.1315  - 0.1628 }{\sqrt{0.1485(1-0.1485) [\frac{1}{578} + \frac{1}{688}  ]}  }[/tex]  

=> [tex]z =  -1.56 [/tex]  

Generally the p-value  is mathematically represented as

          [tex]p-value =  P(z <  -1.56 )[/tex]

From z-table  

         [tex]P(z <  -1.56 ) =  0.05938[/tex]

So

     [tex]p-value =  0.05938 [/tex]

Polynomial function R is the difference of two degree-2 polynomial functions P and Q. What are the possible degrees of R? Explain.

Answers

Answer:

D. The possible degrees are 0, 1, and 2 because it cannot be higher than the degree of either P or Q but it can be less depending on which terms cancel.

Step-by-step explanation:

The possible degrees are 0, 1, and 2. Let's explain why by assuming the following is given:

P = 6x² - 3x - 2

Q = 3x² + 2x - 6

Let R = P - Q

Thus:

(6x² - 3x - 2) - (3x² + 2x - 6)

Open parentheses by distributing the factor of -1

6x² - 3x - 2 - 3x² - 2x + 6

Add like terms together

6x² - 3x² - 3x - 2x - 2 + 6

R = 3x² - 5x + 4

The leading term of R has a degree of 2. Therefore, the difference of two degree-2 polynomial functions P and Q can give us a a polynomial function of R with a degree of 2.

Also, let us assume the following:

P = 4x² + 4x - 3

Q = 4x² + x - 8

Let R = P - Q

R = (4x² + 4x - 3) - (4x² + x - 8)

R = 4x² + 4x - 3 - 4x² - x + 8

Collect like terms

R = 4x² - 4x² + 4x - x - 3 + 8

R = 4x + 5 (4x² cancels 4x²)

The leading term of R has a degree of 1. Therefore, the difference of two degree-2 polynomial functions P and Q can give us a a polynomial function of R with a degree of 1.

Also, let us assume the following:

P = x² + 2x - 3

Q = x² + 2x - 8

Let R = P - Q

R = (x² + 2x - 3) - (x² + 2x - 8)

R = x² + 2x - 3 - x² - 2x + 8

Collect like terms

R = x² - x² + 2x - 2x - 3 + 8

R = 5 (x² cancels x², and 2x cancels 2x)

The polynomial R has a degree of 0. Therefore, the difference of two degree-2 polynomial functions P and Q can give us a a polynomial function of R with a degree of 0.

Therefore we can conclude that:

D. The possible degrees are 0, 1, and 2 because it cannot be higher than the degree of either P or Q but it can be less depending on which terms cancel.
