Step-by-step explanation:

In a density curve, the proportion of data is represented by the area under the curve.

Therefore the answer is "area under the curve".

The area under the curve represents the probability or proportion of data within a certain interval. The curve itself represents the distribution of the data and the shape of the curve provides information about the type of distribution (e.g. normal, skew, etc.).

The intervals on both the horizontal and vertical axis are used to measure the density of the data, but they do not represent the proportion of data themselves. The length of the curve has no significance in representing the proportion of data.

Answer:

Let -5x+y=-3 be the first equation, and 3x-8y=24 be the second. Let's manipulate the first equation by adding 5x to both side; resulting in y=-3+5x, or 5x-3. Now let's plug in 5x-3 for wherever y has been in the second formula. 3x-8(5x-3)=24. This is now pretty straightforward to solve for x. We distribute the 8 into (5x-3) and get 3x-40x-24=24. -48=27x. x=-48/27, x=-16/9.

Now let's plug in the x for either one of the equations to get y. 3(-16/9)+8y=24. -16/3+8y=24. 8y=24+16/3. 24y=72+16. 24y=88. y=88/24, y=11/3.

Step-by-step explanation:

When you horizontally stretch the parent function f(x)=x² by a factor of 4, the new function becomes f(x)= (1/4) x².

The function can be stretched or shrunk in different directions to produce new functions that are similar in shape but differ in size and orientation.

When you horizontally stretch the function f(x)=x² by a factor of 4, the function becomes

=> f(x)= (1/4) x².

To understand this, let's look at the equation of the parent function in detail.

The equation of the parent function f(x)=x² can be written as

=> y=x².

The x values represent the horizontal distances from the origin, and the y values represent the vertical distances from the origin.

When you stretch the function horizontally by a factor of 4, it means that the x values will be multiplied by 4. In other words, the distance from the origin in the x direction will be four times larger. The new equation of the stretched function will be

=> y= (1/4) (4x)².

We can simplify this equation to y= (1/4) x².

In mathematical terms, the horizontal stretching of a function is equivalent to multiplying the independent variable (x) by a constant factor. In this case, the constant factor is 1/4. The constant factor of 1/4 in the equation

=> y= (1/4) x²

represents the horizontal stretch by a factor of 4. The effect of this horizontal stretch is that the parabolic shape of the function will be wider and flatter compared to the parent function. The shape of the parabolic graph of the stretched function will be similar to the parent function, but the x values will be multiplied by 4.

Expression A has the same value for upper and lower limits of the integral. The area being integrated has zero width, so its value will be zero, as shown in expression A.

Expression E has the limits reversed from those in expression B, so the value of that integral will be the opposite of the value shown for B. Both of these integral expressions (B, E) are correct.

Answer: The relationship between the distance a car has traveled in miles, d, and the amount of gas left in the tank in gallons, x, can be represented by the equation:

d = r * m

where r is the fuel efficiency of the car in miles per gallon and m is the amount of gas consumed in gallons.

Since x is the amount of gas left in the tank, we can write:

x = m_0 - m

where m_0 is the initial amount of gas in the tank.

Combining the two equations, we get:

d = r * (m_0 - x)

This equation represents the relationship between the distance the car has traveled in miles, d, and the amount of gas left in the tank in gallons, x.

The product of all integers from -99 to -90, including -99 and -90, will be positive.

The product of an even number of negative integers will be positive, while the product of an odd number of negative integers will be negative.

In this case, we have 10 negative integers, which is an even number. Therefore, the product of all these integers will be positive.

However, the product of a positive and a negative integer is negative, so we need to keep track of the sign changes that occur when we multiply the integers.

We can start by multiplying the two extremes, -99 and -90. The product of these two integers is positive, so at this point, the answer is positive. However, as we multiply more and more of the integers between -99 and -90, we'll eventually reach an even number of positive integers

A 0 degree and 90 degree can form a pair of complementary angles, but 90 degree and an angle that is not adjacent cannot form a pair of complementary angles.

In mathematics, complementary angles are two angles whose sum is 90 degrees. So, if one angle is 0 degrees, the other angle would have to be 90 degrees in order for them to be complementary. However, if one angle is 90 degrees, it cannot form a pair of complementary angles with an angle that is not adjacent (i.e. next to it).

To understand why, consider a straight line, which is equivalent to 180 degrees. If one angle is 90 degrees, it takes up half of the line, leaving the other half for the other angle.

If the other angle is not adjacent, it would have to be placed somewhere on the other half of the line, which is already taken up by the 90 degree angle. Therefore, the two angles cannot add up to 90 degrees and cannot be complementary.

Answer:

To avoid cutting out a fraction of an inch, we need to choose a value of x that is a factor of both 36 inches and 48 inches, since those are the lengths of the sides of the rectangular sheet of cardboard we are using.

The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, and 36.

The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.

The largest factor that both 36 and 48 have in common is 12. However, we can't choose x to be 12 inches because that would mean the length and width of the rectangular box would also be 12 inches, which is too small for our purposes.

Therefore, we should choose x to be the next largest factor that both 36 and 48 have in common, which is 6 inches. This means we will cut six 6-inch by 8-inch rectangles from the cardboard sheet.

The dimensions of the rectangular box will be:

Length = 2x + 2h = 2(6 in) + 2(8 in) = 12 in + 16 in = 28 in

Width = 2x + 2w = 2(6 in) + 2(12 in) = 12 in + 24 in = 36 in

Height = h = 8 in

Therefore, the dimensions of the rectangular box are 28 inches by 36 inches by 8 inches

a) The value of P(A∩B) = 0.

b) The value of P(A|B) = 0.

c) P(A|B) is not equal to P(A). A and B are independent events.

d) The statement "Mutually exclusive events and independent events are really the same, and that if events are mutually exclusive they must be independent." is not accurate.

e) We can conclude that mutually exclusive events have a probability of intersection of zero and are not independent.

a) Since A and B are mutually exclusive, they cannot occur at the same time, so P(A∩B) = 0.

b) The conditional probability of A given B is defined as the probability of A occurring given that B has occurred. Since A and B are mutually exclusive, if B has occurred, then A cannot occur. Therefore, P(A|B) = 0.

c) No, P(A|B) is not equal to P(A). Since B has occurred, the sample space has been reduced to only those outcomes in which B has occurred. Therefore, the probability of A given that B has occurred can only be determined from the portion of the sample space in which both A and B occur.

However, since A and B are mutually exclusive, this probability is zero. Therefore, P(A|B) ≠ P(A).

d) The statement is not accurate. Mutually exclusive events and independent events are different concepts. Two events are mutually exclusive if they cannot occur at the same time, whereas two events are independent if the occurrence of one event does not affect the probability of the other event.

If two events are mutually exclusive, they are not independent because the occurrence of one event precludes the occurrence of the other event.

e) Mutually exclusive events have a relationship where if one event occurs, the other cannot. In contrast, independent events are events where the occurrence of one event does not affect the probability of the other event occurring.

Therefore, we can conclude that mutually exclusive events and independent events are not the same concept, and we must be careful not to confuse them.
