Which of the following is completely factored?O 5x2 (2xy + 12x2)O 3.r(522 - 6x + 3)O r(14.ry + 5.0 - 10x2)

Answers

ANSWER

[tex]3x(5x^2-6x+3)[/tex]

EXPLANATION

We want to identify the option that is completely factored.

For an expression to be completely factored, it means that there are no more common terms between the terms in the expression.

That means it can not be factored any further.

Therefore, the only correct option is:

[tex]3x(5x^2-6x+3)[/tex]

4. Create an equation for a 6th degree polynomial that only has the zeros of x=5, -4, -6, 1 with a y-intercept of 3600. Explain how you found your equation.

Answers

Since the y-intercept of the polynomial must be 3600, then:

[tex]p(0)=3600[/tex]

Since the only zeroes of the polynomial must be x=5, -4, -6 and 1, then the factors of the polynomial, are:

[tex]\begin{gathered} (x-5) \\ (x+4) \\ (x+6) \\ (x-1) \end{gathered}[/tex]

Let the multiplicity of the factor (x-1) be equal to 3 and let the multiplicity of the rest of the factors to be equal to 1. Then:

[tex]p(x)=a(x-5)(x+4)(x+6)(x-1)^3[/tex]

Where a is a constant. Notice that the degree of that polynomial is 6. Evaluate it at x=0 to find the value of a that makes the y-intercept to be equal to 3600:

[tex]\begin{gathered} p(0)=a(0-5)(0+4)(0+6)(0-1) \\ =a(-5)(4)(6)(-1) \\ =120a \end{gathered}[/tex]

Since p(0)=3600, then:

[tex]\begin{gathered} 3600=120a \\ \Rightarrow a=\frac{3600}{120} \\ \Rightarrow a=30 \end{gathered}[/tex]

Therefore, the following polynomial is a 6th degree polynomial with zeroes at the values of 5, -4, -6 and -1 with a y-intercept equal to 3600:

[tex]p(x)=30(x-5)(x+4)(x+6)(x-1)^3[/tex]

Answers

Based on the number of teachers who voted for the skating rink and those who voted for the bowling alley, the ratio of votes for skating to bowling is 30 : 13

How to find the ratio?

The ratio can be found by taking a ratio of those who voted for the skating rink against those who voted for the bowling alley. This ratio should then be taken to its simplest form.

Number of votes for bowling alley = 13 votes

Number of votes for skating rink = 30 votes

The ratio of votes for the skating rink to those of the bowling alley is:

Answer:

A. Total area of Alaska is considerable larger than total area of Connecticut.

B. Population of California is considerably larger that population of Alaska.

Step-by-step explanation:

A. What is the difference in total area of Alaska and Connecticut?

According to the US government, total areas of Alaska and Connecticut are 663,268 square miles and 5,567 square miles, respectively.

The difference between both quantities is:

[tex]x=6.633 \times 10^{5} mi^{2} -5.567 \times 10^{3} mi^2\\x=6.577 \times 10^{5} mi^2[/tex]

Which means that total area of Alaska is considerable larger than total area of Connecticut.

B. What is the difference in total population of California and Alaska?

According to the US government, total populations of California and Alaska are 39,512,223 people and 710,249 people, respectively.

The difference between both quantities is:

[tex]x=3.951 \times 10^7 people - 7.103 \times 10^5 people\\x=3.880 \times 10^7 people[/tex]

Which means that population of California is considerably larger that population of Alaska.

A large university accepts ​%50 of the students who apply. Of the students the university​ accepts, ​%45 actually enroll. If 30,000 students​ apply, how many actually​ enroll?

Answers

6,750

Explanation:
30,000 students applied and the university only accepts 50%

50% of 30,000 is 15,000
So 15,000 students were accepted

But 45% actually enroll.
45% of 15000 that was accepted = 6,750 students actually enrolled.

The value of the 'k' for the given polynomial is found as 1.

What is termed as the division of polynomial?The algorithm for dividing polynomials is used to accomplish a rational number which symbolizes a polynomial divided by the a monomial or the other polynomial. The divisor and dividend are placed in the same manner as in regular division. Dividing polynomials is a math operation in which we divide one polynomial by another, usually with a lower degree than the dividend.

For the given question;

Dividend = x³ - 2x² + kx + 3Divisor = x - 1Remainder = 3

By the remainder theorem,

Put x - 1 = 0. x = 1, in the polynomial will be equal to its remainder.

Put x = 1 in the polynomial.

x³ - 2x² + kx + 3 = 3

1³ - 2(1)² + k(1) + 3 = 3

1 - 2 + k = 0

k = 1

What is a regression equation?

Generally, Y is represented by the equation Y = a + bX + e, which represents the regression equation. The value of the dependent variable, which is referred to as Y, is what is being explained or predicted.

a, also known as Alpha, is a constant; it is equal to the value of Y when the value of X is equal to 0. b, also known as Beta, is the coefficient of X; it is the slope of the regression line.

In conclusion,

Sum of X = 34

Sum of Y = 44

Mean X = 6.8

Mean Y = 8.8

Sum of squares (SSX) = 48.8

Sum of products (SP) = 56.8

Step-by-step explanation:

∠ R = 2x + 5 , ∠ S = x + 1 , ∠ T = 7x - 16

the sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

2x + 5 + x + 1 + 7x - 16 = 180

10x - 10 = 180 ( add 10 to both sides )

10x = 190 ( divide both sides by 10 )

x = 19

Then

∠ R = 2x + 5 = 2(19) + 5 = 38 + 5 = 43°

∠ S = x + 1 = 19 + 1 = 20°

∠ T = 7x - 16 = 7(19) - 16 = 133 - 16 = 117°

Number Showing on Top Face Frequency

Answers

For the cube to land with a 5 or 6 on the top face, a 2/5 probability is needed.

The table displays the outcomes of 20 rolls of a number cube with faces labeled from 1 to 6.

To ascertain the experimental likelihood that 5 or 6 will appear on the top face of the number cube the following time it is rolled.

The ratio of likely outcomes to all possible outcomes is known as the probability.

Total frequency = 3 plus 3 plus 6 plus 3 plus 5 equals 20.

Total frequency of positive results = 3 + 5 = 8

Therefore according to the probability it is no. of possible outcomes divided by total outcomes.

Here favorable cases are 8 which are positive results

Total out come ( frequency) is 20

Probability is 8/20, or 2/5.

Therefore, there is a 2/5 chance that the cube will land with a 5 or 6 on the top face.

Time is the continuous movement of existence and the events that take place from the past, present, and onward into the future in what appears to be an unbreakable order. It is a quantity that is a component of numerous measurements that are used to rank events, compare how long they endure, compare the length of occurrences or the gaps between them, and measure how quickly things change in the real world or in our conscious experience. Time is frequently referred to as a fourth dimension in addition to the three spatial dimensions.

The major problem that Steven will face is he can't decide the winner among the racers who have very little difference in time.

the time t required to repair a machine is an exponentially distributed random variable with mean 2.5 (hours). what is the probability that a repair takes at least 1212 hours given that its duration exceeds 12 hours?

Answers

The probability that a repair takes at least 1212 hours is 0.67.

With a mean of 2.5 hours, the repair time is treated as an increasingly random variable.

Because the inverse of the mean is the parameter of the exponential distribution, λ = 0.4 [tex]h^{-1}[/tex].

The probability that a repair duration will transcend k hours may well be described as follows:

P(t > K) = [tex]e^{-\lambda t}[/tex] = [tex]e^{-0.4t}[/tex]

Given that a repair takes over 11 hours, the conditional likelihood that it will take at least 12 hours,

The exponential distribution has a discrete-time feature, which means that the probability of future events is not affected by previous events.

In this example, the conditional chance that a repair will take at least 10 hours is equal to the possibility that a repair will take at least (12 - 11) = 1 hour.

In Mathematics, the y-intercept of any graph such as a linear function, generally occur at the point where the value of "x" is equal to zero (x = 0).

By critically observing the graph (see attachment), the coordinates of the y-intercept of this line is given by y-intercept = (0, 6), which represents the graphic designer's expenses on advertising for the month of July.

What is x-intercept?

In Mathematics, the x-intercept can be defined as the point at which the graph of any function crosses the x-coordinate and the value of "y" is equal to zero (0).

From the graph (see attachment), we can logically deduce that the x-intercept represents the number of hours which the graphic designer would have to work, in order to cover his expenses (on advertising) for the month of July.
