Therefore, the conditional pdf of x given y = y is f(x|y=y) = 4/9.

In order to find the conditional pdf of x given y = y, we need to use the formula:
f(x|y=y) = f(x,y) / f(y)
First, we need to find f(y) by integrating f(x,y) with respect to x from 0 to y, and then integrating the resulting expression with respect to y from y to 4:
f(y) = ∫ from y to 4 ∫ from 0 to y 1/8 dx dy = 3/32
Next, we can substitute f(x,y) = 1/8 and f(y) = 3/32 into the formula for the conditional pdf:
f(x|y=y) = 1/8 / (3/32) = 4/9

Therefore, the conditional pdf of x given y = y is f(x|y=y) = 4/9.

To determine the vector representing the shorter ramp, we must multiply the vector representing the first ramp by a scalar, whose value lies between 0 and 1.

These are the quantities that only have magnitude.

These are the quantities that have both magnitude and direction.

Given:

From this, we can observe that the magnitude of the first ramp is greater than that of the second ramp. Because of a smaller magnitude, in order to obtain a vector for the second ramp from the first ramp, we will multiply a scalar value, ranging from 0 to 1 with the vector of the first ramp.

Hence, to determine the vector representing the shorter ramp, we must multiply the vector representing the first ramp by a scalar between 0 and 1.

The p-value for testing H0 (null hypothesis) versus Ha (alternative hypothesis) is 0.0038. We need to determine whether H0 would be rejected at different significance levels: α = 0.10, α = 0.05, α = 0.01, and α = 0.001.

To make the decision, we compare the p-value with the chosen significance level. If the p-value is less than or equal to the significance level, we reject H0. Otherwise, we fail to reject H0.

At α = 0.10: Since the p-value (0.0038) is less than 0.10, we reject H0.

At α = 0.05: Since the p-value (0.0038) is less than 0.05, we reject H0.

At α = 0.01: Since the p-value (0.0038) is greater than 0.01, we fail to reject H0.

At α = 0.001: Since the p-value (0.0038) is greater than 0.001, we fail to reject H0.

In summary:

H0 would be rejected at α = 0.10 and α = 0.05.

H0 would not be rejected at α = 0.01 and α = 0.001.

Please note that the decision to reject or fail to reject the null hypothesis depends on the chosen significance level, and different levels of significance can lead to different conclusions.

Answer:

175 degrees

Step-by-step explanation:

So we see that this is a supplementary angle, which means it is equal to 180/ So set the equations up and solve for x:

\(180=29+(x-5)\\180=24+x\\156=x\\\)

Then, plug 156 back into the equation:

\(180-5\\175\)

Therefore, your answer is 175 degrees

Step-by-step explanation:

Given 30% of the 50,000 books in the library are fiction, you want to know the percentage that are non-fiction, and the number of fiction books.

The total of all books in the library is 100%, so if 30% are fiction, the remaining number are not:

  100% -30% = 70%  . . . . are non-fiction

The number of fiction books is found by multiplying the total number by the fraction that are fiction:

  fiction books = 50,000 × 0.30 = 15,000

There are 15,000 fiction books in the library.

Therefore, it would take approximately 10.246 hours for the satellite to fly 82000 miles.

We can use the concept of unit rate to solve this problem.

Given that the satellite flies 73680 miles in 9.21 hours, we can calculate the unit rate of the satellite's speed:

Unit Rate = Distance / Time

= 73680 miles / 9.21 hours

≈ 8004.55 miles/hour

Now, to find out how long it would take for the satellite to fly 82000 miles, we can use the unit rate:

Time = Distance / Unit Rate

= 82000 miles / 8004.55 miles/hour

Calculating this value:

Time ≈ 10.246 hours

The area of the kitchen that Carolyn needs to tile is A = 248 feet²

Given data ,

Let the area of the kitchen that Carolyn needs to tile is A

Now , the figure consists of a rectangle and a trapezoid

Now , the area of rectangle is R = 8 x 16

R = 128 feet²

Now , the area of the remaining trapezoidal figure is T

T = ( 8 + 16 ) ( 18 - 8 ) ( 1/2 )

T = 120 feet²

Answer:

y = 2x + 2

Explanation:

We can use the following equation to write an equation in slope-intercept form.

Where (x1, y1) is a point in the line and m is the slope. Additionally, the slope can be calculated as:

Where (x2, y2) is another point in the line.

So, replacing (x1, y1) by (0, 2) and (x2, y2) by (3, 8), we get that the slope is equal to:

Finally, replacing m by 2 and (x1, y1) by (0, 2), we get:

Therefore, the equation in slope-intercept form is:

y = 2x + 2

Given the equation:

To be able to select which graph represents the equation, we will complete the coordinates of points at two conditions - when x = 0 and y = 0.

Once we get the set of coordinates, let's determine among the graphs which correctly reflects the two points.

Let's start,

First Point: At x = 0,

x - y = -2

0 - y = -2

-y/-1 = -2/-1

y = 2

(0,2)

Second Point: At y = 0,

x - y = -2

x - 0 = -2

x = -2

(-2,0)

We now got the coordinates of the two points that pass through the line graph of the equation. (0,2) and (-2,0)

Among the given graphs, naming A, B, C, D, E, F respectively from the upper left to the lower right, graph F reflects the correct coordinates of the two points we got.

Therefore, Graph F is the appropriate graph of the equation x - y = -2.

The answer is A. The normal distribution in its standardized form has a mean of 0 and a standard deviation of 1. This means that the distribution is centered around 0, and the spread of the data is determined by the standard deviation of 1. This is useful in statistical analysis because it allows us to compare data from different distributions on a standardized scale.

The normal distribution is a continuous probability distribution that is often used in statistical analysis. It is characterized by a bell-shaped curve and is symmetrical around its mean. In its standardized form, the normal distribution has been transformed to have a mean of 0 and a standard deviation of 1. This transformation is achieved by subtracting the mean of the distribution from each data point and dividing by the standard deviation. This standardization allows us to compare data from different normal distributions on a standardized scale.

The normal distribution has many properties that make it useful in statistical analysis. It is often used as a model for many real-world phenomena, such as the distribution of human height, IQ scores, and many others. The normal distribution is also useful because it is well understood and has many mathematical properties that make it easy to work with.

I did some maths

the acosta family went out to dinner. the price of the meal was $79.85. if the tip was 15%.The Acosta family paid $91.83 for the meal, including the 15% tip.

To calculate the total amount paid, we need to add the original price of the meal to the tip amount. The price of the meal was $79.85, and the tip was 15% of that amount. To find the tip, we multiply $79.85 by 0.15 (or 15% expressed as a decimal), which equals $11.98. Adding the tip of $11.98 to the original price, the total amount paid is $91.83.

In more detail, a 15% tip means that 15% of the meal price is added as an extra amount to the bill. To calculate the tip, we multiply the meal price ($79.85) by 0.15 (or 15% as a decimal), resulting in $11.98. This represents the additional amount the Acosta family paid for the tip. To find the total amount paid, we add the tip amount to the original meal price: $79.85 + $11.98 = $91.83. Therefore, the Acosta family paid $91.83 for the meal, including the tip.
