Answer:

-1, 5/2 ; f(x) = (x+1)(2x-5)

Step-by-step explanation:

2x² - 3x - 5 = 0

2x² - 5x + 2x - 5 = 0

x(2x - 5) +1(2x - 5) = 0

Factors are :

(2x - 5) = 0 ; (x + 1) = 0

2x - 5 = 0

2x = 5

x = 5/2

(x + 1) = 0

x = - 1

Zeros are ; x = 5/2 and x = - 1

Answer:

The p-value of the test is 0.5028>0.05, which means that there is sufficient evidence to determine that 68% represents the state in question.

Step-by-step explanation:

Test if 68% represents the state in question.

This means that at the null hypothesis, we test if the proportion is 68%, that is:

[tex]H_0: p = 0.68[/tex]

At the alternate hypothesis, we test if the proportion is different of 68%, that is:

[tex]H_a: p \neq 0.68[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

0.68 is tested at the null hypothesis:

This means that [tex]\mu = 0.68, \sigma = \sqrt{0.68*0.32}[/tex]

32 of the 44 online courses at this particular community college were taught by full-time faculty.

This means that [tex]n = 44, X = \frac{32}{44} = 0.7273[/tex]

Test statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.7273 - 0.68}{\frac{\sqrt{0.68*0.32}}{\sqrt{44}}}[/tex]

[tex]z = 0.67[/tex]

P-value of the test and decision:

The p-value of the test is the probability of finding a sample proportion differing by the population proportion by at least 0.7273 - 0.68 = 0.0473, which is P(|z| > 0.67), which is 2 multiplied by the p-value of z = -0.67.

Looking at the z-table, z = -0.67 has a p-value of 0.2514

2*0.2514 = 0.5028

The p-value of the test is 0.5028>0.05, which means that there is sufficient evidence to determine that 68% represents the state in question.

On solving the provided question we cans ay that -  order when writing it on the number line: = -1.25, -0.75, 0.25, 1.5, 2

A number line is a visual representation of real numbers used in introductory mathematics. It is an image of a magnitude line. On the number line, each point represents a real number, and each real number is taken to represent a point. Increments on a number line are separated by equal distances. You can only respond to the numbers on a line in the manner indicated by those numbers. How the number is utilized is determined by the question that goes with it. B: Make a point.

The numbers on the number line must be

On solving the provided question we can say that by logarithm the statement is true he is short.

The logarithm is a power's reciprocal in mathematics. Accordingly, the exponent by which b must be raised to obtain a number x equals the logarithm of that number in base b. For instance, since 1000 = 103, its base-10 logarithm is 3, or log10 = 3. As an illustration, the base 10 logarithm of 10 is 2, while the square of 10 is 100. Log 100 = 2. To answer a question like, For example, how many times must a base of 10 be multiplied by itself to achieve 1,000, a logarithm (or log) is the mathematical term utilized. The solution is 3 (1,000 = 10 10 10).

1. The number that must be multiplied by (5x + 6) to result in the expression 20x + 24 is 4.

2. An expression representing the miles driven on each day of the road trip and a final simplified expression of the total drives in three days are as follows:

a) Day 1: x

b) Day 2: 2x + 10

c) Day 3: x - 100

d) Final simplified expression to represent total miles driven in three days: 4x + 10 - 100.

e) A real-world situation in which order matters when writing the expression x - 100 is that the value of x is supposed to be more than the value of 100.

A mathematical expression is the combination of constants, numbers, mathematical operators, and variables without the equation sign (=).

Literarily, a mathematical expression is like a phrase in the English language because it does not make complete sense without the equation sign.

1) Multiplication:

(20x + 24) ÷ (5x + 6) = 4

Check:

4(5x + 6) = 20x + 24

2) Road Trip Expressions:

Day one driving distance = x miles

Day two driving distance = 2x + 10

Day three driving distance = x - 100

Total distance = x + 2x + 10 + x - 100

= 4x + 10 - 100

The probability that a rental car delivered to the firm will need a tune-up is 0.05% and the conditional probability is 0.04%

The probability that a rental car delivered to the firm will need a tune-up

From the question, we have the following parameters that can be used in our computation:

Agency 1 = 0.42%,   Tune up from agency 1 = 0.08%

Agency 2 = 0.08%,   Tune up from agency 2 = 0.02%

Agency 3 = 0.5%,    Tune up from agency 3 = 0.02%

Using total probability, we have the following equation

P(tune-up) = P(tune-up | agency 1) * P(agency 1) + P(tune-up | agency 2) * P(agency 2) + P(tune-up | agency 3) * P(agency 3)

Substitute the known values in the above equation, so, we have the following representation

P(tune-up) = 0.08% * 0.42% + 0.02% * 0.08% + 0.02% * 0.5%

Evaluate the sum of products

P(tune-up) = 0.000452

Express as percentage and approximate

P(tune-up) = 0.05%

(b) The probability that it came from agency 2

This is a conditional probability, and it calculated as

P(Agency 2| Tune up) = P(Tune up and Agency 2)/P(Tune up)

Substitute the known values in the above equation, so, we have the following representation

P(Agency 2| Tune up) = (0.02% * 0.08%)/0.0452%

Evaluate

P(Agency 2| Tune up) = 0.0003539823

Express as percentage

P(Agency 2| Tune up) = 0.03539823%

Approximate

P(Agency 2| Tune up) = 0.04%

So, the probability is 0.04%
