The equation representing the cost of the canoe rental company is given by y = 30x + 20 .

Let the total cost for renting a canoe be y.

Let the canoe is being rent for x hours.

now the cost for renting the canoe at 30 dollars per hour = 30x

Total cost of renting the canoe = 30x + 20

But the total cost is y.

Hence the equation to represent this situation is given by

y = 30x + 20 which is a straight line of the form y = mx +c, where the slope is 30 and the y-intercept is 20.

Now we will plot the graph for this equation.

At x = 0 , y = 20

At x = 1 , y = 50

At x= -3 , y = -70

Hence the graph of the line passes through these points on the cartesian plane.

Answer:

100

Step-by-step explanation:

85 +80+100+85+x(the unknown),/the number of numbers ie 5

350+x/5=90

350+x=90 * 5

350+x=450

x=450-350

x=100

The score on the last test in order to have a test average of 90 is 100.

Given that, Rob's first four test scores are 80, 85, 100 and 85.

We need to find the score on the last test in order to have a test average of 90.

By definition, an average is the arithmetic mean of the sum of all the values divided by the total number of values in a given set. An average is calculated for those sets of values which are more or less the same. The term average describes the numeric value that represents a large amount of data. An average can be derived by calculating the ratio of the sum of all the values to the number of units or values.

Let the score on the last test be x.

Now, average=(80+85+100+85+x)/5 =90

⇒350+x=450

⇒x=100

Therefore, the score on the last test in order to have a test average of 90 is 100.

Answer:

Jacob should take the normal route

Step-by-step explanation:

The given parameters are;

How late is Jacob running for work = 5 minutes

The number of times Jacob has taken the alternative route to work = 16 times

The number of times Jacob has taken the normal route to work = 27 times

The number of times Jacob has been late when he takes the alternative route to work = 8 times

The number of times he has been on-time = 3 times

The number of times he has been early = 5 times

By taking the normal route;

The number of times he has been late = 9 times

The number of times he has bee on-time = 12 times

The number of times he has been early = 6 times

Therefore, we have;

The probability that Jacob will be on-time or early when he takes the alternative route. P(A) = (3 + 5)/16 = 0.5

The probability that Jacob will be on-time or early when he takes the normal route, P(N) = (12 + 6)/27 = 0.\(\overline 6\)

Therefore, given that the probability that Jacob will arrive on-time or early when he takes the normal route is higher than the probability when he takes the alternative route, Jacob should take the normal route.

Last week Bob was paid total of $480 for the items that he produced that week and this week Bob produced 2 items more than last week and was paid a total of $510 for the items that he produced this week.

Let's start with the simplest case:

he produced 36 or less items this week.

In this case he produced less than 36 items last week too.

So he was paid the same amount of dollar per item. Using assumptions (1) and (2), we have:

$480 + 2X = $510

⇒2X=510-480$

⇒2X=$30

⇒2X=$30/2

⇒X=$15

He was paid $15 per item.

Last week he received his $480.

480/15= 32 items.

This week he received his $510.

510/15=34 items. Other cases have no solution.

If MSwithin is smaller than MSbetween, then increasing MSwithin and/or decreasing MSbetween will lead to an increase in the F statistic.

The F statistic is calculated by dividing the variance between groups (MSbetween) by the variance within groups (MSwithin). Therefore, to increase the value of the F statistic, either the numerator (MSbetween) needs to increase, or the denominator (MSwithin) needs to decrease.

So, the answer is:

a. MSwithin > MSbetween

If the variance within groups (MSwithin) is reduced or the variance between groups (MSbetween) is increased, the F statistic will increase. Therefore, if MSwithin is smaller than MSbetween, then increasing MSwithin and/or decreasing MSbetween will lead to an increase in the F statistic.

The solution to the given differential equation 2xy(dy/dx) = y², with the initial condition y(2) = 3, is y = (27 * e⁽ˣ⁻²⁾\()^{1/4}\).

To solve the given differential equation

2xy(dy/dx) = y²

We will use separation of variables and integrate to find the solution.

Start with the given equation

2xy(dy/dx) = y²

Divide both sides by y²:

(2x/y) dy = dx

Integrate both sides:

∫(2x/y) dy = ∫dx

Integrating the left side requires a substitution. Let u = y², then du = 2y dy:

∫(2x/u) du = ∫dx

2∫(x/u) du = ∫dx

2 ln|u| = x + C

Replacing u with y²:

2 ln|y²| = x + C

Using the properties of logarithms:

ln|y⁴| = x + C

Exponentiating both sides:

|y⁴| = \(e^{x + C}\)

Since the absolute value is taken, we can remove it and incorporate the constant of integration

y⁴ = \(e^{x + C}\)

Simplifying, let A = \(e^C:\)

y^4 = A * eˣ

Taking the fourth root of both sides:

y = (A * eˣ\()^{1/4}\)

Now we can incorporate the initial condition y(2) = 3

3 = (A * e²\()^{1/4}\)

Cubing both sides:

27 = A * e²

Solving for A:

A = 27 / e²

Finally, substituting A back into the solution

y = ((27 / e²) * eˣ\()^{1/4}\)

Simplifying further

y = (27 *  e⁽ˣ⁻²⁾\()^{1/4}\)

Therefore, the solution to the given differential equation with the initial condition y(2) = 3 is

y = (27 * e⁽ˣ⁻²⁾\()^{1/4}\)

Step-by-step explanation:

The F-value directly using the given variances and degrees of freedom:

F = s1² / s2² = 35.7 / 50.4 ≈ 0.7083

To compare the variation in car rental rates at the airport versus downtown, we can use an F-test. The F-test compares the variances of two samples.

Given:

Variance of rental rates at the airport (s1²) = 35.7

Variance of rental rates downtown (s2²) = 50.4

The F-test statistic is calculated as the ratio of the larger variance to the smaller variance:

F = s1² / s2²

In this case, we want to determine the test value to use in the F-test. The test value is the critical value from the F-distribution table corresponding to a specific level of significance (α) and degrees of freedom.

The degrees of freedom for the numerator (airport) is n1 - 1, and the degrees of freedom for the denominator (downtown) is n2 - 1.

Given that there were 8 cars at the airport (n1 = 8) and 5 cars downtown (n2 = 5), the degrees of freedom are:

df1 = n1 - 1 = 8 - 1 = 7

df2 = n2 - 1 = 5 - 1 = 4

To find the test value, we consult the F-distribution table or use statistical software. Since the options provided are not test values from the F-distribution table, we need to calculate the F-value directly using the given variances and degrees of freedom:

F = s1² / s2² = 35.7 / 50.4 ≈ 0.7083

Answer:

The correct equation is \(2\frac{2}{3}+r = 3\).

Why?

To find the correct answer we have to isolate r from the other numbers. To isolate r  from this equation, we have to subtract \(2\frac{2}{3}\) from both sides of the equation. Remember that you can do whatever you need to one side of the equation, but you must do the exact same thing to the other side, so the equation remains the same value. By subtracting \(2\frac{2}{3}\) from the equation, we get \(2\frac{2}{3}-2\frac{2}{3}+r=3-2\frac{2}{3}\). Simplify: \(r=\frac{1}{3}\). Therefore, answer D is the solution.

To approximate the integral ∫2.4 to 2 f(x) dx using Simpson's rule, we divide the interval [2, 2.4] into subintervals and approximate the integral within each subinterval using quadratic polynomials.

Given the data points (x, f(x)) = (2, 0.6931), (2.2, 0.7885), and (2.4, 0.8755), we can use Simpson's rule to approximate the integral.

Step 1: Determine the step size, h.

Since we have three data points, we can divide the interval [2, 2.4] into two subintervals, giving us a step size of h = (2.4 - 2) / 2 = 0.2.

Step 2: Calculate the approximations within each subinterval.

Using Simpson's rule, the integral within each subinterval is given by:

∫f(x)dx ≈ (h/3) * [f(x₀) + 4f(x₁) + f(x₂)]

where x₀, x₁, and x₂ are the data points within each subinterval.

For the first subinterval [2, 2.2]:

∫f(x)dx ≈ (0.2/3) * [f(2) + 4f(2.1) + f(2.2)]

≈ (0.2/3) * [0.6931 + 4(0.7885) + 0.8755]

For the second subinterval [2.2, 2.4]:

∫f(x)dx ≈ (0.2/3) * [f(2.2) + 4f(2.3) + f(2.4)]

≈ (0.2/3) * [0.7885 + 4(0.4545) + 0.8755]

Step 3: Sum up the approximations.

To obtain the approximation of the total integral, we sum up the approximations within each subinterval.

Approximation ≈ (∫f(x)dx in subinterval 1) + (∫f(x)dx in subinterval 2)

Calculating the values, we get the final approximation of the integral ∫2.4 to 2 f(x) dx using Simpson's rule.

For the entire independent-measures experiment 24 individuals are participated.

Different participants are utilized in each condition of the independent variable in an experimental design known as an independent measures design, or between-groups. This indicates that a different group of participants is present for each condition of the experiment. A research strategy known as an independent measures design uses numerous experimental groups with subjects only being assigned to one group. Throughout the experiment, each participant is solely exposed to one independent variable condition. A drug trial for a novel medicine would serve as an example. This has the benefit of preventing order effects, which occur when participants behave differently as a result of the order in which conditions are done, often as a result of factors like boredom or exhaustion.

We are given the value  t(22) = 5.30, p < .01

So here degree of freedom (df) is 22 and it is independent so there is two samples,

so df= n₁+n₂-2

⇒ 22 =  n₁+n₂-2

⇒ n₁+n₂ = 24.

The ellis weight is heavier and by 7.23 lbs.

We are given that;

Weight= 5pounds

Now,

To convert Ed’s weight from kilograms to pounds, we can multiply by the conversion factor of 2.20462262185. We get:

Ed’s weight in pounds = 50 kg * 2.20462262185 lbs/kg Ed’s weight in pounds = 110.2311310925 lbs

To convert Ellis’s weight from stones and pounds to pounds, we can multiply the number of stones by 14 and add the number of pounds. We get:

Ellis’s weight in pounds = 7 stones * 14 lbs/stone + 5 lbs Ellis’s weight in pounds = 98 + 5 Ellis’s weight in pounds = 103 lbs

To compare the weights, we can subtract them and see which one is larger. We get:

Ed’s weight - Ellis’s weight = 110.2311310925 lbs - 103 lbs Ed’s weight - Ellis’s weight = 7.2311310925 lbs
