= 0.182.

hello

to answer precisely, i have to see the graphs in the question but overall, the answer should look like something like the graph in the attached file

Answer:

Step-by-step explanation:

Well, since the length of a month can vary in the number of days, this answer can also vary.

For example, February is only 28 days long, while December is 31 days long.

That being said, the average length of all 12 months is 30.436875 days, so if Denny left to another country on June 20th, he would most likely be back   July 19th of July 20th.

Answer:

144ft^3

Step-by-step explanation:

To start, we have your formula: \(V=\frac{1}{2} (bh) (l)\)
b = base length of the triangle.
h = height of the triangle.
l = length of the prism

Fill in for each of those values:
\(V = \frac{1}{2} (6x6)(8)\)

\(V=\frac{1}{2} (36)(8)\)

\(V=(18)(8)\)

\(V=144\)

Your answer, because it is a 3D shape, should be cubed, so:
\(V=144ft^{3}\)

Answer:

68% of the data points lie between 10 and 18.

Step-by-step explanation:

one standard deviation to left of mean = 14 - 4 =10

one standard deviation to right of mean = 14 + 4 = 18

68% of data is in this region.

so the answer is 68% of the data points lie between 10 and 18.

the averaged speed of the car is 70 miles per hour.

Step-by-step explanation:

Answer:

\(n=(\frac{1.960(0.18)}{0.03})^2 =138.30\)

So the answer for this case would be n=139 rounded up to the nearest integer

Step-by-step explanation:

For this case we have the following info given:

\(\bar X = 5.5\) the sample mean

\(s = 0.18\) the standard deviation

The margin of error is given by this formula:

\( ME=z_{\alpha/2}\frac{s}{\sqrt{n}}\)    (a)

And on this case we have that ME =0.03 and we are interested in order to find the value of n, if we solve n from equation (b) we got:

\(n=(\frac{z_{\alpha/2} s}{ME})^2\)   (b)

The critical value for 95% of confidence interval now can be founded using the normal distribution and if we look in the normal standard distirbution we got \(z_{\alpha/2}=1.96\), replacing into formula (b) we got:

\(n=(\frac{1.960(0.18)}{0.03})^2 =138.30\)

So the answer for this case would be n=139 rounded up to the nearest integer

The joint cumulative distribution function Fx1,x2 (u, v) is equal to the joint cdf FX2,X1 (u, v), but X1 and X2 are not necessarily independent. The conditional expectation of X1 and X2 given X1 + X2 are different, and M and Z are dependent.

(a) The joint cumulative distribution function (cdf) Fx,,X2 (u, v) = P(X1 ≤ u, X2 ≤ v) is the same as the joint cdf FX2,X₁ (u, v) = P(X2 ≤ u, X1 ≤ v).

This is true because fX1,X2 (s, t)=fX1,X2 (t, s) for all s, t, which implies that Fx,,X2 (u, v) = P(X1 ≤ u, X2 ≤ v) = P(X2 ≤ u, X1 ≤ v) = FX2,X₁ (u, v).

(b) The two independent random variables are called X1 and X2.

This is false because the joint density fx1,x2 (s, t) does not necessarily imply that X1 and X2 are independent. For two random variables to be independent, the joint density of the two variables must be equal to the product of the marginal densities of the two variables.

(c) The conditional expectation E[X1 X1 + X2] is equal to the conditional expectation E[X2|X1 + X2].

This is false because the conditional expectation of X1 given X1 + X2 is different from the conditional expectation of X2 given X1 + X2.

(d) The random variable M = max{X1, X2} is independent of the indicator random variable Z = 1x₁>X2.

This is false because the random variable M = max{X1, X2} is dependent on the indicator random variable Z = 1x₁>X2. If X1 > X2, then M = X1 and Z = 1, and if X2 > X1, then M = X2 and Z = 0. Therefore, M and Z are dependent.

Step-by-step explanation:

From the given points (negative 2, negative 1), (0, 1), (2, 3), we can determine the domain and range.

The domain represents the set of all possible x-values of the points, and the range represents the set of all possible y-values of the points.

In this case, we can see that the x-values are -2, 0, and 2, and the corresponding y-values are -1, 1, and 3.

Therefore, the correct answer is:

Answer: 392.

Step-by-step explanation:

Answer:

B. about 5 days.

Step-by-step explanation:

If you average;

400 miles per day

1990 miles trip would take?

Cross multiplying gives;

\(\frac{1990 * 1}{400}\) = 4.975 days

Rounding off the answer to nearest day gives 5 days.

Hence the 1990 miles journey should take about 5 days.

A trip of 1990 miles would take around 5 days if you averaged 400 miles each day. Option B is correct.

It is described as the single number that embodies the mean value for the specified collection of data or the closed value for each item in the specified set of data.

It is given that, you averaged 400 miles per day,

We have to find the days would a trip of 1990 miles takes.

The number of days is obtained by taking the ratio of the total distance we have to travel to the distance traveled by the person in one day.

Suppose the number of days needed to complete the trip will be x,

x=Total distance/distance in one day

x=1990 / 400

x= 4.975 days

x≈5 days

If you averaged 400 miles each day, a trip of 1990 miles would take around 5 days.

Thus, option B is correct.

Therefore, if 24 teaspoons of vegetable oil were used, we would need 16 teaspoons of vinegar to make the recipe correctly.

According to a salad recipe, each serving requires 6 teaspoons of vegetable oil and 9 teaspoons of vinegar. If 24 teaspoons of vegetable oil were used, we can determine the amount of vinegar needed for the recipe to be correct as follows:

First, we must determine the ratio of vinegar to oil in the recipe. To do this, we divide the amount of vinegar needed per serving (9 teaspoons) by the amount of oil needed per serving (6 teaspoons):

9 ÷ 6 = 1.5

This means that for every 1.5 teaspoons of oil used, we need 1 teaspoon of vinegar. Next, we use this ratio to determine the amount of vinegar needed when 24 teaspoons of oil are used:

1.5 ÷ 1 = 1.5

(teaspoons of oil per 1 teaspoon of vinegar)

24 ÷ 1.5 = 16

Answer:

$26,986.29

Step-by-step explanation:

We can use the formula for calculating the depreciation of an asset over time:

wor

\(\bold{D = P(1 - \frac{r}{100} )^t}\)

where:

D= the current value of the asset

P = the initial purchase price of the asset

r = the annual depreciation rate as a decimal

t = the number of years the asset has been in use

In this case, we have:

P = $39,600

r = 12% = 0.12

t = 3 years

Substituting these values into the formula, we get:

\(D= 39,600(1 - \frac{12}{100})^3\\D= 39,600(1 - 0.12)^3\\D= 39,600*0.88^3\\D= 39,600*0.681472\\D=26986.2912\)

Therefore, the car is worth approximately $26,986.29 after 3 years of depreciation at a rate of 12% per annum.

Answer:

$26,986.29

Step-by-step explanation:

As the car's value depreciates at a constant rate of 12% per annum, we can use the exponential decay formula to create a function for the value of the car f(t) after t years.

\(\boxed{f(t)=a(1-r)^t}\)

where:

In this case, the initial value is $39,600, and the rate of depreciation is 12% per year. Therefore, the function that models the value of the car after t years is:

\(f(t)=39600(1-0.12)^t\)

\(f(t)=39600(0.88)^t\)

To calculate the value of the car after 3 years, substitute t = 3 into the function:

\(\begin{aligned} f(3)&=39600(0.88)^3\\&=39600(0.681472)\\&=26986.2912\\&=26986.29\;(\sf 2\;d.p.)\end{aligned}\)

Therefore, the car is worth $26,986.29 after 3 years.

Yes, there is a difference in the shapes of the displacement-time graphs for uniform acceleration towards the positive direction, uniform acceleration towards the negative direction, uniform deceleration towards the positive direction, and uniform deceleration towards the negative direction.

Uniform acceleration towards the positive direction:

In this case, the object's velocity increases in the positive direction over time. The displacement-time graph will have a concave-upward shape, forming a curve that starts with a small slope and gradually becomes steeper as time progresses.

Uniform acceleration towards the negative direction:

Here, the object's velocity increases in the negative direction, meaning it accelerates in the opposite direction to its positive direction.

The displacement-time graph will have a concave-downward shape, forming a curve that starts with a steep slope and gradually becomes less steep as time progresses.

Uniform deceleration towards the positive direction:

In this scenario, the object's velocity decreases in the positive direction, but it still moves towards the positive direction.

The displacement-time graph will show a curve with a decreasing slope, forming a concave-downward shape, indicating that the object is slowing down.

Uniform deceleration towards the negative direction:

Here, the object's velocity decreases in the negative direction, opposing its initial direction.

The displacement-time graph will have a curve with a decreasing slope, forming a concave-upward shape, indicating that the object is slowing down but still moving in the negative direction.

In summary, the shapes of the displacement-time graphs differ based on the direction and type of acceleration (positive or negative) and whether the object is undergoing uniform acceleration or uniform deceleration. These differences can be observed through the concavity and slope of the graphs.
