The total charge as a function of time is

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

Time          Price

1/2 hour    $7.00

1 hour       $12.00

2 hours    $17.00

All day     $25.00

For 1/2 hour to 1 hour, we have

Rate = (12 - 7)/(1 - 1/2)

Rate = 10

So, we have

C(t) = 10t + c

Where c is the initial value

So, we have

c = C(t) - 10t

c = 7 - 10 * 1/2 = 2

So, we have

C(t) = 10t + 2, for t < 2

For 2 hours, the rate is

C(t) = 17 for t = 2

Lastly, we have

C(t) = 25 for t > 2

Answer:

-3/2

Step-by-step explanation:

Parallel lines have the same slope, but different y-intercepts. We can find the slope by converting to slope-intercept form:

[tex]\displaystyle 3x+2y=8\\\\2y=8-3x\\\\y=4-\frac{3}{2}x\\\\y=-\frac{3}{2}x+4[/tex]

Hence, the slope of the parallel line will also be -3/2

The property that justifies the work between Step 3 and Step 4 is the property of real numbers under multiplication and division.

A relationship between two expressions or values that are not equal to each other is called 'inequality.

The given inequality is 19 < 4x - 5

By the addition property, add 5 on both sides

19 + 5 < 4x - 5 + 5

24<4x

By Multiplication and division property, divide both sides by 4

(1/4)24<(1/4)4x

6<x

Hence, the property that justifies the work between Step 3 and Step 4 is the property of real numbers under multiplication and division.

The equation representing the number of beads varies directly with the number of inches of the string is y = 9x.

In its most basic form, a ratio is a comparison between two comparable quantities.

There are two types of proportions One is the direct proportion, whereby increasing one number by a constant k also increases the other quantity by the same constant k, and vice versa.

If one quantity is increased by a constant k, the other will decrease by the same constant k in the case of inverse proportion, and vice versa.

Given, The number of beads varies directly with the number of inches of string.

The expected value of the number of rolls necessary to roll a specific number is 6. This is because each roll has an equal probability of rolling the desired number, which is 1/6.

The expected value of the number of rolls necessary to roll a specific number can be calculated by multiplying the probability of rolling the desired number by the total number of rolls. In this case, since the random number generator is a six-sided die, the probability of rolling a specific number, such as a six, is 1/6. Therefore, the expected value of the number of rolls necessary to roll a six would be 6 (1/6 x 6 = 6). This is because each roll has an equal probability of rolling the desired number. To calculate the expected value for any number, simply multiply the probability of rolling the desired number (1/6) by the total number of rolls. For example, if the desired number is a five, the expected value would be 5 (1/6 x 5 = 5). If the desired number is a three, the expected value would be 3 (1/6 x 3 = 3). Thus, the expected value of the number of rolls necessary to roll a specific number is equal to the number itself.

The complete question: Given a discrete random number generator, such as a six-sided die, what is the expected value of the number of rolls necessary to roll a specific number (e.g. a six)?

Directed numbers, also known as integers, are numbers that have a direction or sign, either positive (+) or negative (-). They are used to represent quantities that have direction, such as temperature, height, weight, etc.

Rob borrows 15 dollars first

He later borrows 3 dollars.

Since we are to drag numbers to write an equation using NEGATIVE integers only,

We have -$15 + -$3 = -$18 which is Rob's debt

If numbers may be used more than once, the equation is

Null hypothesis: The population mean daily number of texts for 18-24 year olds is equal to the population mean daily number of texts for 25-34 year olds.

To test whether the population mean daily number of texts for 18-24 year olds differs from the population mean daily number of texts for 25-34 year olds, we need to set up a null hypothesis. The null hypothesis states that the population mean daily number of texts for 18-24 year olds is equal to the population mean daily number of texts for 25-34 year olds. This means that there is no difference in the mean daily number of texts between the two groups. We can then use this null hypothesis to test the data from our sample to see if the difference in means is statistically significant. If the test results show that the difference in means is statistically significant, then we can reject the null hypothesis and conclude that the two population means are significantly different.

A P-value is the probability of obtaining a test statistic as extreme or more extreme than the one observed, assuming the null hypothesis is true. In this case, the P-value of 0.022 means that there is a 2.2% chance of observing the test statistic if the null hypothesis (μ = 1) were true.

A confidence interval, on the other hand, provides a range of values that are believed to contain the true population mean with a certain level of confidence. The confidence level (e.g. 95%) indicates the degree of certainty that the interval contains the true mean.

A low P-value suggests that the data provide strong evidence against the null hypothesis, and a confidence interval that does not contain the null value supports the alternative hypothesis. However, it is not guaranteed that a 95% or 99% confidence interval will include the value 1 or 0 just based on the P-value obtained from a hypothesis test.
