One-to-one: Since f(2) = f(-2) = -4, the function is not one-to-one.

(a) f: R → R. f(x) = x^2

The function f is neither onto nor one-to-one. To see why, consider the following:

Onto: A function is onto if every element of the co-domain has at least one pre-image in the domain. In this case, f(x) = x^2 can never be negative, so it does not take on every value in the co-domain R (since R includes negative numbers). Therefore, the function is not onto.

One-to-one: A function is one-to-one if each element in the co-domain corresponds to exactly one element in the domain. However, since f(-x) = f(x) for all x, the function is not one-to-one. For example, f(2) = f(-2) = 4.

(b) g: R → R. g(x) = x^3

The function g is both onto and one-to-one. To see why:

Onto: For any y in the co-domain R, we can find x in the domain R such that g(x) = y by taking the cube root of y. Therefore, g is onto.

One-to-one: Suppose g(a) = g(b) for some a, b in the domain R. Then, we have a^3 = b^3, which implies a = b. Therefore, g is one-to-one.

(c) h: Z → Z. h(x) = x^3

The function h is onto but not one-to-one. To see why:

Onto: For any y in the co-domain Z, we can find x in the domain Z such that h(x) = y by taking the cube root of y. Therefore, h is onto.

Not one-to-one: For example, h(-1) = (-1)^3 = -1 and h(1) = 1^3 = 1, so h is not one-to-one.

(d) f. 2+2, f(x) = -4

The function f is neither onto nor one-to-one. To see why:

Onto: The co-domain is not specified, so it is not clear whether the function is onto or not.

Not one-to-one: Since f(2) = f(-2) = -4, the function is not one-to-one.

It takes 9 hours for the car to travel 612 miles at an average speed of 68 miles per hour.

To find the time it takes for the car to travel 612 miles at an average speed of 68 miles per hour, we can use the formula:

time = distance ÷ speed

Plugging in the given values, we get:

time = 612 miles ÷ 68 miles per hour

Therefore, the time it would take the car to travel 612 miles is: Time = 612 miles / 68 miles per hour Time = 9 hours.  So, it would take the car approximately 9 hours to travel a distance of 612 miles if it maintains an average speed of 68 miles per hour.

Answer:

84.3%

Step-by-step explanation:

Percentage of people completed the task under 40 s is(rounded) 84.3%

There were approximately 304,657,600 Americans in July 2009. The correct answer is 304,657,600.  In July 2009, the estimated population of the United States would be 304,657,600 people. To calculate this, we need to take the 2008 population of 302,000,000 and multiply it by the growth rate of 0.88%.

First, we need to find the amount of growth that occurred between 2008 and 2009. We can do this by multiplying the 2008 population by the growth rate:

302,000,000 x 0.88% = 2,657,600

This tells us that the population increased by 2,657,600 people from 2008 to 2009. To find the total population in 2009, we need to add this growth to the 2008 population:

302,000,000 + 2,657,600 = 304,657,600

Therefore, in July 2009, the estimated population of the United States would be 304,657,600 people, based on a growth rate of 0.88%.

Inference means a statement according to the data.  The chart is a survey on which subject is their favorite, not necessarily their performance but they want you to surmise things about performance.

A.  Most of the students must do best in math because they favor math most.

B.  Social studies was voted as one of least like subjects; they must get good grades in social studies.

C. Boys must do well in science.

Rounded to the hundredth place, this gives us answer choice (D), which is the correct answer. So we can say with 90% confidence that the average number of hours of sleep for working college students is between 6.46 and 6.54 hours.

To calculate the confidence interval using the t-distribution, we use the formula:

Confidence interval = sample mean ± (t-score)*(standard error)

where the standard error is calculated as the standard deviation divided by the square root of the sample size, i.e.,

standard error = standard deviation / sqrt(sample size)

In this case, Morgan sampled 101 students and found an average of 6.5 hours of sleep with a standard deviation of 2.14. So the standard error is:

standard error = 2.14 / sqrt(101) = 0.213

The t-score for a 90% confidence level with 100 degrees of freedom (n-1) is 1.660, as given in the problem.

Therefore, the confidence interval is:

Confidence interval = 6.5 ± (1.660)*(0.213) = (6.46, 6.54).

Two cheeseburgers contain a total of 1120 calories (2 x 560) and one small order of fries contains 230 calories. And three cheeseburgers contain a total of 1680 calories (3 x 560) and two small orders of fries contain a total of 460 calories (2 x 230).

Let's use a system of equations to solve for the caloric content of each item.

Let x be the number of calories in one cheeseburger and y be the number of calories in one small order of fries.

From the first statement, we know that:

2x + y = 1350

From the second statement, we know that:

3x + 2y = 2140

We can use these two equations to solve for x and y. First, we'll solve for y in terms of x by rearranging the first equation:

y = 1350 - 2x

Now we can substitute thisn expression for y into the second equation:

3x + 2(1350 - 2x) = 2140

Simplifying this equation, we get:

3x + 2700 - 4x = 2140

-x = -560

x = 560

So one cheeseburger contains 560 calories. We can plug this value back into either of the original equations to solve for y:

2(560) + y = 1350

y = 230

So one small order of fries contains 230 calories.

The set of vectors {[1/√18], [1/√2], [-2/3]} and {[4/√18], [0], [-2/3]} is an orthonormal set.

To verify whether a set of vectors is orthonormal, we need to check two conditions: orthogonality and normalization. Orthogonality means that the dot product of any two distinct vectors in the set is zero. Normalization means that the magnitude or length of each vector is 1.

First, we check for orthogonality. The dot product of the first and second vectors is:
[1/√18] * [4/√18] + [1/√2] * [0] + [-2/3] * [-2/3] = 4/18 + 0 + 4/9 = 8/18

The dot product of the first and third vectors is:
[1/√18] * [1/√2] + [1/√2] * [(-2/3)] + [-2/3] * [(-1/√18)] = 1/√36 - 2/3√2 - 2/3√2 = 0

The dot product of the second and third vectors is:
[4/√18] * [1/√2] + [0] * [-2/3] + [-2/3] * [(-1/√18)] = 2/√36 + 2/√36 = 4/√36

Since the dot product of any two distinct vectors is not always zero, the set is not orthogonal. We need to normalize the vectors to produce an orthonormal set.

To normalize a vector, we divide it by its magnitude. The magnitude of a vector [a, b, c] is √(a^2 + b^2 + c^2). Thus, the normalized version of the first vector is:
[1/√18, 1/√2, -2/3] / √[(1/18) + (1/2) + (4/9)] = [1/√2, √(2/9), -2/√9]

The normalized version of the second vector is:
[4/√18, 0, -2/3] / √[(16/18) + 0 + (4/9)] = [2/√9, 0, -2/√9]

The normalized version of the third vector is:
[1/√18, -1/√2, -2/3] / √[(1/18) + (1/2) + (4/9)] = [1/√2, -√(2/9), -2/√9]

We can now check for orthogonality again:

The dot product of the first and second vectors is:
[1/√2] * [2/√9] + [√(2/9)] * [0] + [-2/√9] * [(-2/√9)] = 0

The dot product of the first and third vectors is:
[1/√2] * [1/√2] + [-√(2/9)] * [-2/√9] + [-2/√9] * [-2/√9] = 1/2 + 2/9 + 4/9 = 1

The correct statement of the hypotheses is option B: H0:π≥0.75 and H1:π<0.75.

In a hypothesis test problem, the null hypothesis (H0) represents the status quo or the default assumption, while the alternative hypothesis (H1) represents the claim or the research question that the investigator wants to test.

In this problem, the null hypothesis is that the population proportion (π) is greater than or equal to 0.75 (i.e., H0:π≥0.75). The alternative hypothesis is that the population proportion is less than 0.75 (i.e., H1:π<0.75), which is what we are testing for.

The p-value of 0.0735 represents the probability of obtaining a sample proportion as extreme as the one observed or more extreme, assuming that the null hypothesis is true. Since the p-value is less than the significance level (usually set at 0.05), we reject the null hypothesis and conclude that there is sufficient evidence to support the alternative hypothesis. Therefore, the correct statement of the hypotheses is option B.

The expected value of rolling a 4 on a six-sided die is 1/6. Therefore, in a single roll, we can expect to see a 4 appear approximately 1/6 of the time. Each group of students rolls the die 75 times, so we can expect each group to roll a 4 approximately (1/6)*75 = 12.5 times.
With 8 groups participating, we can expect a total of approximately 8*12.5 = 100 times that a 4 is rolled.

To find the most likely total number of times a 4 was rolled, follow these steps:

1. Determine the probability of rolling a 4 on a six-sided die: There is 1 favorable outcome (rolling a 4) and 6 possible outcomes (rolling a number 1 through 6). So, the probability of rolling a 4 is 1/6.

2. Calculate the expected number of times a 4 is rolled in a single group: Since each student group rolls the die 75 times, the expected number of times a 4 is rolled in one group is the probability of rolling a 4 multiplied by the number of rolls: (1/6) * 75 = 12.5.

3. Determine the most likely total number of times a 4 was rolled across all 8 groups: Multiply the expected number of times a 4 is rolled in one group by the total number of groups: 12.5 * 8 = 100.

Slope (b1) = r * (Sy/Sx)
where r is the correlation coefficient, Sy is the standard deviation of the response variable, and Sx is the standard deviation of the explanatory variable.

Slope (b1) = 0.944 * (1.64/29.51) = 0.0522 (rounded to the hundredths place)
