Answer:

The correct answer is given by option a.

Step-by-step explanation:

Rational roots theorem:

In the rational roots theorem, we take the leading coefficient(which multiplies the term of x with the highest exponent) and the independent term(which does not multiply any value of x).

The possible roots have the format p/q, in which p are the factors of the independent term, and q are the factors of the leading coefficient.

In this question:

Leading coefficient: 3

Independent term: 15

Factors of the independent term: {1, 3, 5, 15} -> p

Factors of the leading coefficient: {1,3} -> q

Possible roots:

All possible values, positive or negative, in which p is divided by q. So

[tex]\pm \frac{1}{1}, \pm \frac{1}{3}, \pm \frac{3}{1}, \pm \frac{3}{3}, \pm \frac{5}{1}, \pm \frac{5}{3}, \pm \frac{15}{1}, \pm \frac{15}{3}[/tex]

So, without the repeated terms, they are:

[tex]\pm \frac{1}{3}, \pm \frac{5}{3}, \pm 1, \pm 3, \pm 5, \pm 15[/tex]

The correct answer is given by option a.

Answer:

10a and 5a+2a+3a

Step-by-step explanation:

6a + 4a = 10a

10a = 10a

9a is not equal to 10a

10+a is not equal to 10a

5a+2a+3a = 10a

6a - 4a is not equal to 10a

a^10 is not equal to 10a

Answer:

P(939.6 < X < 972.5) = 0.6469

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

CNNBC recently reported that the mean annual cost of auto insurance is 965 dollars. Assume the standard deviation is 113 dollars.

This means that [tex]\mu = 965, \sigma = 113[/tex]

Sample of 57:

This means that [tex]n = 57, s = \frac{113}{\sqrt{57}} = 14.97[/tex]

Find the probability that a single randomly selected policy has a mean value between 939.6 and 972.5 dollars.

This is the pvalue of Z when X = 972.5 subtracted by the pvalue of Z when X = 939.6. So

X = 972.5

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{972.5 - 965}{14.97}[/tex]

[tex]Z = 0.5[/tex]

[tex]Z = 0.5[/tex] has a pvalue of 0.6915

X = 939.6

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{939.6 - 965}{14.97}[/tex]

[tex]Z = -1.7[/tex]

[tex]Z = -1.7[/tex] has a pvalue of 0.0446

0.6915 - 0.0446 = 0.6469

So

P(939.6 < X < 972.5) = 0.6469

Answer:

[tex]x = \frac{ - 13}{16} [/tex]

Step-by-step explanation:

[tex]f(x) = {x}^{3} + 3 \\ g(x) = {x}^{2} + 2[/tex]

At the point of intersection, f(x)=g(x)

[tex] {x}^{3} + 3 = {x}^{2} + 2 \\ collect \: like \: terms \\ {x}^{3} - {x}^{2} + 3 - 2 = 0 \\ {x}^{3} - {x}^{2} + 1 = 0[/tex]

[tex] {x}^{3} - {x}^{2} + 1 = 0[/tex]

The above graph is that of the equation

[tex] {x}^{3} - {x}^{2} + 1 = 0[/tex]

The solution is = -0.755 which is approximately -0.8

From the option provided;

For option A, x = -13/16 = -0.8125

For option B, x = -5/4 = -1.25

For option C, x = -15/16 = -0.9375

For option D, x = -7/8 = -0.875

From the option provided, The closest to the solution is Option A

Because - 0.8125 is approximately -0.8

The answer after performing mathematical operation is 8.97998 .

What is mathematical operations?

  In order to add, subtract, multiply, or divide two or more quantities, one must perform a series of four fundamental operations known as mathematical operations. They involve the study of numbers and the order of operations, which are important in all other areas of mathematics like algebra, data processing, and geometry. Without employing mathematical operation rules, we are unable to solve the issue. The addition, subtraction, multiplication, and division operations all follow the same four fundamental rules.

Here the given ,

=> 5.87998 + 3.100

=>  5.87998

  + 3.10000

--------------------

    8.97998

=> 5.87998+3.100=[8.97998]

Hence after performing mathematical operations the answer is 8.97998.

Answer:

x=8

Step-by-step explanation:

Answer:

35

Step-by-step explanation:

I am assuming you want me to answer the equation provided in the picture, therefore I will provide you with the answer.

So we have [tex]\frac{3}{5} x[/tex] = 21

When it comes to equations with a variable, our goal is to isolate the variable, so let's start.

[tex]\frac{3}{5} x[/tex] = 21

1. Combine multiplied terms into a single fraction :

[tex]\frac{3x}{5}[/tex] = 21

2. Multiply both sides by the denominator :

5 * 3/5 = 3

5 * 21 = 105

3x = 105

3. Divide both sides by 3 :

[tex]\frac{3x}{3} = \frac{105}{3 }[/tex]

x = 35

Step-by-step explanation:

Answer:

Step-by-step explanation:

Sum = -5

Product = -14

Factors = 2 , (-7)      because 2*(-7) = -14 and 2 + (-7) = -5

x²  - 5x - 14 = 0

x² + 2x - 7x - 14 = 0

x(x + 2) -7(x + 2) = 0

(x + 2)(x - 7) =0

x + 2 = 0           ;  x -7 =0

     x = -2  ;            x  = 7
