Kaylee would travel 544 miles in 17 hours if she continued at the same rate.

A mathematical number is known as distance measures "how much ground an object has traveled" while moving. Distance is defined as the product of speed and time.

distance = rate × time

We know that Kaylee drove 160 miles in 5 hours, so her rate is:

rate = distance / time = 160 miles / 5 hours = 32 miles/hour

Now we can use this rate to find out how far she would travel in 17 hours:

distance = rate × time

distance = 32 miles/hour × 17 hours

distance = 544 miles

Therefore, Kaylee would travel 544 miles in 17 hours if she continued at the same rate.

y=2x-2 is the equation of the graph.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

From the given figure the points are (2, 2)(3,4)(4, 6)

m=6-4/4-3

m=2/1

slope =2

Now let us find the y intercept

4=2(3)+b

4=6+b

b=-2

y=2x-2

Hence, y=2x-2 is the equation of the graph.

From the given information, upon calculation, the volume of the larger solid is 192.

When two similar solids have a scale factor of 3:4, it means that the corresponding lengths of the two solids are in a ratio of 3:4. Since volume is a three-dimensional measurement, it depends on the cube of the length. Therefore, the volume of the larger solid will be the cube of the scale factor multiplied by the volume of the smaller solid.

Given that the volume of the smaller solid is 54, we can calculate the volume of the larger solid as follows:

Volume of the smaller solid = 54

Scale factor = 3:4

Volume of the larger solid = (scale factor^3) * Volume of the smaller solid

= (4/3)^3 * 54

= (64/27) * 54

= 192

Therefore, the volume of the larger solid is 192.

When two similar solids have a scale factor of 3:4, the volume of the larger solid can be found by cubing the scale factor and multiplying it by the volume of the smaller solid. In this case, if the volume of the smaller solid is 54, the volume of the larger solid is 192.

The solution to the system of equations y = 1.5x - 4 and y = -x  is (1.6,-1.6). The correct answer is D.

The solution to the system of equations can be calculate as follows

From the question we can conclude that the equations are :

y = 1.5x - 4

y = -x

to find the value of x and y  we can substitute y = -x in the first equation so it became

-x = 1.5x - 4

-1.5x - x = -4

-2.5x = -4

x = 1.6

after we found the value of x we can find the value of y by Substitute

x = 1.6 in y = -x

y = -1.6

Therefore, the solution to the y = 1.5x - 4 and y = -x  is (1.6,-1.6).

Answer:

\(AC=20\)

Step-by-step explanation:

The line segment AC is the entire length of the line. Within this segment, point  B is found.

Point B, in a way, splits the segment into two, creating the segments AB and BC.

To find the length of AC, add the lengths of the lines AB and BC together:

\(AB=11\\BC=9\\AB+BC=AC\\11+9=AC\\20=AC\)

The length of AC is 20.

:Done

Answer:

20 units.

Step-by-step explanation:

Segment AC is broken into two parts by point B. That means that the length of segment AB plus the length of segment BC equals the length of segment AC.

If BC = 9, and AB = 11, AC = 9 + 11 = 20 units.

The horizontal asymptote occurs at y = 0. The absolute value of θ becomes large, the value of the tangent function approaches zero.

The function y = tan(πθ) belongs to the period π, which means that it repeats every π units along the x-axis.

For this function, there are two asymptotes: a vertical asymptote and a horizontal asymptote.

The vertical asymptotes occur at θ = -π/2, π/2, 3π/2, etc.

These values make the denominator of the tangent function equal to zero, resulting in an undefined value.

The horizontal asymptote occurs at y = 0.

As the absolute value of θ becomes large, the value of the tangent function approaches zero.

This means that the graph of y = tan(πθ) gets closer and closer to the x-axis but never touches it.

Regression analysis is a statistical technique used to predict the value of a quantitative variable based on another quantitative variable i.e., the given statement is true.

Regression analysis is widely used when there is an interest in understanding how one quantitative variable, known as the dependent variable or response variable, is influenced by another quantitative variable, known as the independent variable or predictor variable.

The goal is to establish a mathematical relationship between the variables that can be used for prediction and inference.

In regression analysis, a model is built based on the observed data to estimate the relationship between the variables. The model takes into account the variability in the data and provides insights into the strength and direction of the relationship.

By analyzing the model's coefficients, such as the slope and intercept, predictions can be made about the dependent variable's values for different levels of the independent variable.

Regression analysis allows for the assessment of the significance of the relationship, the quantification of the effect of the predictor variable on the response variable, and the estimation of the prediction accuracy.

It provides a valuable tool for making informed decisions, conducting research, and understanding the underlying factors that contribute to the variability of the dependent variable.

Therefore, it is true that regression analysis is useful when predicting the value of a quantitative variable based on another quantitative variable.

Answer:

To find the probability P(X = 2), we need to use the moment generating function (MGF) and the formula for the nth moment of a random variable:

Mx(t) = E[e^(tx)] = Σ [x^n P(X = x) e^(tx)]

Taking the second derivative of the MGF with respect to t, we get:

Mx''(t) = E[X^2 e^(tx)]

Setting t = 0.5 in the MGF, we get:

Mx(0.5) = 1 - 0.1e

where e is the mathematical constant e = 2.71828...

Taking the second derivative of the MGF with respect to t, we get:

Mx''(t) = 3.6e^(2t) for t < -ln(0.1)

Mx''(t) = ∞ for t ≥ -ln(0.1)

Therefore, we can write:

E[X^2] = Mx''(0) = 3.6e^0 = 3.6

Using the formula for the variance of a random variable:

Var(X) = E[X^2] - E[X]^2

We need to find E[X] first.

Taking the first derivative of the MGF with respect to t, we get:

Mx'(t) = E[X e^(tx)]

Setting t = 0.5 in the MGF, we get:

Mx'(0.5) = 1.8e

Therefore, we can write:

E[X] = Mx'(0) = 1.8

Now we can find the variance:

Var(X) = E[X^2] - E[X]^2 = 3.6 - 1.8^2 = 0.72

Finally, we can find the probability P(X = 2) using the formula for the probability mass function (PMF) of a discrete random variable:

P(X = 2) = e^(-λ) λ^k / k!

where λ is the expected value of the random variable, which is also the parameter of the Poisson distribution.

In this case, λ = E[X] = 1.8, and k = 2.

Therefore, we can write:

P(X = 2) = e^(-1.8) (1.8)^2 / 2! ≈ 0.1638

Rounding to 4 decimal places, we get:

P(X = 2) ≈ 0.1638

The correct answer is- we can be 99% confident that the true mean waiting time is between 4.16 and 12.84 minutes.

A doctor took a random sample of n = 6 patients to see how long they each spent in the waiting room. She wants to construct a t interval for the mean waiting time with 99% confidence. The times in the sample were roughly symmetric with a mean of z = 8.5 minutes and a standard deviation of sx = 2.8 minutes. We have to find the 99% confidence interval of the waiting time.

The formula for the confidence interval is shown below:\(\[\large \bar x-t_{\alpha/2}\frac{s}{\sqrt{n}} < \mu < \bar x+t_{\alpha/2}\frac{s}{\sqrt{n}}\]\)

Where: \(\[\large \bar x\]\) is the sample mean \(\[s\]\) is the sample standard deviation \(\[n\]\) is the sample size\(\[\large t_{\alpha/2}\]\) is the t-score from the t-distribution with (n - 1) degrees of freedom, where α is the level of significance

The sample mean is\(\[\large\bar x=8.5\]\) and the sample standard deviation is \(\[\large s=2.8\].\)

Since the sample size is small, we must use a t-distribution with n - 1 degrees of freedom. With 99% confidence, α = 0.01/2 = 0.005.

Using a t-table for 5 degrees of freedom and α = 0.005, we get\(\[\large t_{\alpha/2}\] = 4.032.\)

On substituting the values, we get the interval as shown below: \(\[\large 8.5-4.032\frac{2.8}{\sqrt{6}} < \mu < 8.5+4.032\frac{2.8}{\sqrt{6}}\]\)

The confidence interval is (4.16, 12.84).

Therefore, we can be 99% confident that the true mean waiting time is between 4.16 and 12.84 minutes
