The expression of time in terms of r is T = 85/9r. If he walked at an average speed of 3 miles per hour. Then the time taken by nick to reach the shopping mall will be 3 hours and 60 minutes.

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

Nick walked 5 miles to reach his aunt's house.

From there he traveled 8 miles to the shopping mall on a bicycle.

He traveled 80% faster on the bicycle than on foot.

Let r represent his rate of walking in miles per hour. Then the 1.8r will be the rate of cycling in miles per hour.

Then the number of hours nick took to reach the shopping mall in terms of r will be

T = t₁ + t₂

Where t₁ is the time taken to reach his aunt's house and t₂ is the time taken to reach the shopping mall from his aunt's house. Then we have

T = 5 / r + 8 / 1.8r

T = 1/r (5 + 8/1.8)

T = 85/9r

If r is 3 miles per hour, then the time taken by nick to reach the shopping mall will be

T = 85 / (9 x 3)

T = 3.15 hours

T = 3 hours and 9 minutes

after 4 years, Amy's investment is worth $8587.80. This represents a loss of $3912.20 (or 31.3% of the initial investment).

If Amy's investment loses 9% of its value each year, then the amount of money she has after 4 years can be calculated as follows:

First, we need to calculate the percentage of the initial investment that remains after one year. Since the investment loses 9% each year, the percentage of the initial investment that remains after one year is:

100% - 9% = 91%

Next, we can calculate the amount of money that remains after one year by multiplying the initial investment by the percentage that remains:

$12500 x 91% = $11375

We can repeat this process for each subsequent year by multiplying the remaining amount from the previous year by 91%:

Year 2: $11375 x 91% = $10362.25

Year 3: $10362.25 x 91% = $9431.36

Year 4: $9431.36 x 91% = $8587.80

Amy looses  $8587.80 after 4 years of investment.

The correlation coefficients of 0.5 and -0.67 are not near zero, as they indicate a moderate to strong relationship between the variables being studied.

A correlation coefficient near zero means that there is little to no relationship between the two variables being studied.

Based on this definition, the correlation coefficients that can be classified as near zero are 0.13, 0.002, and -0.22. The values of 0.13 and -0.22 are close to zero and therefore indicate a weak correlation between the variables.

The value of 0.002 is very close to zero and suggests almost no correlation between the variables.

The p-value for the hypothesis test is approximately 0.65.

To find the p-value for the hypothesis test, we need to determine the test statistic and the corresponding probability.

First, we need to state the null and alternative hypotheses:

Null Hypothesis: The mean number of alcoholic drinks for college students at the liberal arts college is equal to the mean number of alcoholic drinks for U.S. college students in general, which is 4.73.

Alternative Hypothesis: The mean number of alcoholic drinks for college students at the liberal arts college is not equal to the mean number of alcoholic drinks for U.S. college students in general.

Next, we need to determine the test statistic, which is calculated as follows:

t = (sample mean - hypothesized mean) / (standard deviation / sqrt(sample size))

t = (4.45 - 4.73) / (3.92 / sqrt(70))
t = -0.28 / 0.47
t = -0.596

Using a t-distribution table with 69 degrees of freedom (70 - 1), we find the corresponding two-tailed probability to be 0.553.

Therefore, the p-value for the hypothesis test is 0.553. This means that if we assume the null hypothesis is true, there is a 55.3% chance of observing a sample mean of 4.45 drinks per week or more extreme. Since this p-value is greater than the commonly used significance level of 0.05, we fail to reject the null hypothesis and conclude that there is not enough evidence to suggest that the mean number of alcoholic drinks for college students at the liberal arts college differs from the mean number of alcoholic drinks for U.S. college students in general.
To find the p-value for the hypothesis test, we first need to set up the null and alternative hypotheses:

Null hypothesis (H₀): The mean number of alcoholic drinks for college students at this liberal arts college is equal to the national mean (µ = 4.73).
Alternative hypothesis (H₁): The mean number of alcoholic drinks for college students at this liberal arts college is different from the national mean (µ ≠ 4.73).

Next, we'll perform a t-test, since we have a sample mean, standard deviation, and sample size, but not the population standard deviation.

First, calculate the t-statistic:
t = (sample mean - population mean) / (sample standard deviation / √sample size)
t = (4.45 - 4.73) / (3.92 / √70)
t ≈ -0.46

Now, we need to find the degrees of freedom (df) for the t-distribution:
df = sample size - 1
df = 70 - 1 = 69

Using a t-table or t-distribution calculator, we can find the p-value for a two-tailed test (since we're testing for a difference, not specifically greater or lesser) with t ≈ -0.46 and df = 69. The p-value is approximately 0.65.

Your answer: The p-value for the hypothesis test is approximately 0.65.

The normal probability plot determines a normal distribution

An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster in the middle of the range while the remaining ones taper off symmetrically toward either extreme. The distribution's mean is another name for the centre of the range.

Normal distributions are symmetric, uni-modal, and asymptotic, and the mean, median, and mode are all equal

A data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean

Given data ,

Let the normal distribution be represented as N

Now , the normal probability is P

A normal probability plot, also known as a "normal plot," plots sorted data against values chosen to resemble a straight line in the final image if the data are roughly normally distributed.

Divergences from normalcy are shown by deviations from a straight line.

A straight, diagonal line means that you have normally distributed data. If the line is skewed to the left or right, it means that you do not have normally distributed data.

Hence , the normal probability plot determines a normal distribution

Answer:

5/7

Step-by-step explanation:

because it is 5/(2+5)

If the test statistic is -3.11, it means that the observed data is 3.11 standard deviations below the mean of the null distribution.

Since 2.36 is in the rejection region, it means that the critical value for the test is greater than 2.36 in absolute value. This implies that the null hypothesis would be rejected if the test statistic is either less than the negative critical value or greater than the positive critical value.

However, since the test statistic of -3.11 is smaller than the negative critical value, we would fail to reject the null hypothesis. This means that we would conclude that there is not enough evidence to support the alternative hypothesis and we accept the null hypothesis. Therefore, we would have made an incorrect decision if we rejected the null hypothesis based on the given information.

Step-by-step explanation:

The resulting volume when an isosceles triangle with side lengths 5, 5 and 10 is revolved about one of its longer sides is approximately 40.11 cubic units.

Let's call the height of the triangle "h" and the radius of the circle created by the revolution "r". We know that the hypotenuse of the triangle (the longer side) is 10, so we can use the Pythagorean theorem to find the value of h:

h = \(\sqrt{(10^2 - (5/2)^2)}\) = \(\sqrt{25 - 6.25}\) = \(\sqrt18.75}\) = 4.33

Now we can use the formula for the volume of a revolution solid to find the volume:

V = (1/3) * π * \(r^2\) * h

r is half the side length of the triangle, so:

r=5/2

V = (1/3) * π * \((5/2)^2\) * 4.33 = (1/3) * π * 6.25 * 4.33 = 20.55 * π = 40.11 (approximately)

So the resulting volume of the revolved isosceles triangle is approximately 40.11 cubic units.

6.5 represent the change, hence the correct is the change in expected quiz score for every additional one hour students spend on their homework.

The slope of a line tell that how much inclination it has, and in equation it tells the rate of change.

Given that, a linear relationship between the amount of time students spend on their homework and their weekly quiz scores. This relationship can be represented by the equation y = 66 + 6.5x,

When compared to the standard equation of a line, y = mx+c

where m is slope, we get,

The slope of the relationship is 6.5

Since, the slope tells the rate of change, thus 6.5 is telling the change.

Here is the summary of the relation J on all integers:

a. 1 J 2 : No

b. 2 J 1 : Yes

c. 3 J 6 : Yes

d. 17 J 51 : No

e. Another example of x and y in relation J: 4 J 12 (4 is related to 12 under relation J)

To define a relation J on all positive integers is following:

a. No, 1 is not a factor of 2, so 1 does not divide 2.

Therefore, 1 is not related to 2 under relation J.

b. Yes, 2 is a factor of 1 (specifically, 2 divides 1 zero times with a remainder of 1), so 2 divides 1.

Therefore, 2 is related to 1 under relation J.

c. Yes, 3 is a factor of 6 (specifically, 3 divides 6 two times with a remainder of 0), so 3 divides 6.

Therefore, 3 is related to 6 under relation J.

d. No, 17 is not a factor of 51, so 17 does not divide 51.

Therefore, 17 is not related to 51 under relation J.

e. Let's choose x = 4 and y = 12.

Then we need to check if x divides y. We can see that 4 is a factor of 12 (specifically, 4 divides 12 three times with a remainder of 0), so 4 divides 12.

Therefore, 4 is related to 12 under relation J.

Answer:

b = 0.4899

Step-by-step explanation:

Given;

2(2x-1)=5x²

4x - 2 = 5x²

5x² - 4x + 2 = 0

this is a quadratic equation with;

a = 5, b = -4 and c = 2

\(x = \frac{-b \ \ + /-\ \ \sqrt{b^2 - \ 4ac} }{2a} \\\\x = \frac{-(-4) \ \ + /-\ \ \sqrt{(-4)^2 - \ 4(5*2)} }{2(5)} \\\\x = \frac{4 \ \ + /-\ \ \sqrt{16 - \ 40} }{10} \\\\x = \frac{4 \ \ + /-\ \ \sqrt{-24} }{10}\\\\x = \frac{4 \ \ +/-\ \ (\sqrt{24)} (\sqrt{-1} ) }{10} \\\\x = \frac{4 \ \ +/-\ \ (\sqrt{24)} (i )}{10}\\\\ x = \frac{4 \ \ +/-\ \ (4.899) (i )}{10}\\\\ x = \frac{4 \ \ +\ \ (4.899) (i )}{10} \ \ or \ \ x = \frac{4 \ \ -\ \ (4.899) (i )}{10}\\\\\)

in terms of a + bi, it will be simplified as;

\(x = \frac{4}{10} + \frac{(4.899) (i)}{10} \\\\x = 0.4 + 0.4899i\)

Therefore, b = 0.4899

When the given expression is expressed in the simplest form of \(a+bi\)  then the value of b is 0.4899.

Given-

The given expression in the problem is,

\(2(2x-1)=5x^2\)

Simplify this,

\(4x-2=5x^2\)

Arrange the above equation,

\(5x^2-4x+2=0\)

Compare the above equation with general quadratic equation,

\(ax^2+bx+c=0\)

we get,

\(a=5\)

\(b=-4\)

\(c=2\)

Find the roots of the \(x\) . The formula to find the roots of a quadratic equation can be given as,

\(x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a}\)

\(x=\dfrac{-(-4)\pm\sqrt{(-4)^2-4\times5\times2} }{2\times 5}\)

\(x=\dfrac{4\pm\sqrt{16-40} }{10}\)

\(x=\dfrac{4\pm\sqrt{-24} }{10}\)

\(x=\dfrac{4\pm\sqrt{-24}\sqrt{-1} }{10}\)

\(x=\dfrac{4\pm 4.899i} {10}\)

Take positive sign we get,

\(x=\dfrac{4+ 4.899i} {10}\)

Take negative sign we get,

\(x=\dfrac{4-4.899i} {10}\)

Compare the simplified form of  \(a+bi\) with the root of \(x\)

\(x=0.4+ 0.4899i\)

here,

\(b=0.4899\)

Hence when the given expression is expressed in the simplest form of \(a+bi\)  then the value of b is 0.4899.
