Answer: 5 is greater

Step-by-step explanation:

Answer:

14

Step-by-step explanation:

l = length, w = width, h = height.

The surface area of a rectangular prism is:

2lw + 2wh + 2lh.

If the total surface area is 1648, your equation will be:

2lw + 2wh + 2lh = 1648.

lw + wh + lh = 824.

Plug in your width and height values.

16l + 16*20 + 20l = 824.

36l = 504.

Length = 14.

[tex]\boxed{\sf l=14(in)}.[/tex]

[tex]\sf SA=2(wl+hl+hw)[/tex]

Surface area (SA)= 1,648 inches;

Width (w)= 16 inches;

Height (h)= 20 inches.

[tex]\sf 1648(in)=2((16(in))l+(20(in))l+(20(in))(16(in)))[/tex]

Let's remove the units for these steps to make the algebra a little bit easier to understand.

[tex]\sf 1648=2(16l+20l+320)\\ \\1648=2(36l+320)[/tex]

Here, we apply the distributive property of multiplication. Check attached image 1.

[tex]\sf 1648=(2)(36l)+(2)(320)\\\\1648=72l+640[/tex]

[tex]\sf 1648-640=72l+640-640\\ \\1008=72l\\ \\72l= 1008[/tex]

[tex]\sf \dfrac{72l}{72} = \dfrac{1008}{72} \\ \\\\ \boxed{\sf l=14(in)}.[/tex]

If you want to verify this answer simply take the surface area formula for rectangular prisms and calculate the value for the SA using these values of lengh, width and height:

[tex]\sf SA=2((16)(14)+(20)(14)+(20)(16))=\boxed{\sf 1648}. That's\,correct![/tex]

Answer:

The mode is the best measure of center for a distribution that is bimodal, meaning that it has two peaks. In such a distribution, the mean and median may not be representative of the center of the data, but the mode is a good measure of center because it reflects the most common value(s) in the data.

For skewed distributions, the mode may not be a good measure of center because the peak of the distribution is not necessarily at the center of the data. In a normal distribution, the mean, median, and mode are all equal and are good measures of center.

The within-group sum of squares is 58250.44

The degrees of freedom are given as 355

The estimate of the within-groups variance is 164.0657

Variance, as a statistical measure, evaluates the level of variability or dispersion contained in a dataset by inspecting how distant each value in a set is from the mean of that same set.

If there is a higher variance, it signals that data points are more widely distributed and further removed from the mean, whereas if there is a lower variance, one can assume that they are primarily clustered more closely around the mean.

To obtain the variance value, one must determine an average signal-to-noise ratio for each squared difference derived from every respective value taken away from the arithmetic mean. It is no exaggeration to say that variance is progressively employed across diverse subject areas including finance, engineering, and science.

The image point of (-7,-8) after the transformation D1/2oT-1,0 is (-4,4).

First, we apply the translation T-1,0, which moves every point 1 unit to the right (since the x-coordinate is decreased by 1) and leaves the y-coordinate unchanged. Therefore, the image of (-7,-8) under T-1,0 is (-7-1,-8) = (-8,-8).

Next, we apply the dilation D1/2, which scales every distance from the origin by a factor of 1/2. Therefore, the image of (-8,-8) under D1/2 is (-8/2,-8/2) = (-4,-4).

Thus, the image point of (-7,-8) after the transformation D1/2oT-1,0 is (-4,4).

Inverse relationships between operations are used to solve two-step inequalities because they allow us to isolate the variable on one side of the inequality.

A two-step inequality involves two operations that need to be undone in reverse order to solve for the variable. Inverse relationships between operations are used to "undo" these operations, leading to an isolated variable.

For example, consider the inequality 2x + 5 > 11. The first operation being performed on x is multiplication by 2, and the second operation is adding 5. To solve for x, we need to undo these operations in reverse order.

The inverse relationship of multiplication by 2 is division by 2, and the inverse relationship of adding 5 is subtracting 5. Therefore, we can solve the inequality as follows:

2x + 5 > 11

2x > 6 (subtract 5 from both sides)

x > 3 (divide both sides by 2)

Here, we first subtracted 5 from both sides to undo the addition of 5, and then divided both sides by 2 to undo the multiplication by 2.

Inverse relationships between operations are used in two-step inequalities because they help to simplify the equation by undoing the operations one by one, leading to an isolated variable.

By using inverse relationships between operations, we can efficiently and systematically solve two-step inequalities and isolate the variable to find the solution set.

Answer: 5

Step-by-step explanation:

Since x is directly related to the square of y, we can write the equation:

x = ky^2

where k is a constant of proportionality. We can solve for k using the given values of x and y:

16 = k(2^2) -> 16 = 4k -> k = 4

Now that we know k, we can use it to find y when x = 100:

100 = 4y^2 -> 25 = y^2 -> y = ±5

Since y cannot be negative, the only possible value of y is 5. Therefore, when x = 100, y could be 5.

Answer:

One possible value of y when x = 100 is y = 5.

Step-by-step explanation:

Using the direct variation formula, we know that x = ky^2, where k is a constant. Given that x = 16 and y = 2, we can solve for k:

16 = k(2)^2

k = 4

Now we can use this value of k to find y when x = 100:

100 = 4y^2

y^2 = 25

y = 5 or -5 (since the question only asks for one possible value, we can choose either solution)

Therefore, one possible value of y when x = 100 is y = 5.

Answer:

Step-by-step explanation:

To answer this question, we need to know the dimensions of the rectangle and the triangle. Assuming that the triangle is right-angled and has one side coinciding with one side of the rectangle, we can use the formula for the area of a triangle: \ ( \frac {1} {2} \) × base × height1. The base and height of the triangle are the same as the length and width of the rectangle. The area of the rectangle is length × width. The probability that a point chosen randomly inside the rectangle is in the triangle is then the ratio of the area of the triangle to that of the rectangle, which is: \ ( \frac {\frac {1} {2} \times length \times width} {length \times width} \) = \ ( \frac {1} {2} \). So, the probability is 0.5 or 50% to the nearest hundredth2.

Answer:    C  .08

Step-by-step explanation:

Probability is the part out of the whole.  you first need to find the part, which is the triangle

In other words find out how much of the triangle is taking up the rectangle, which is done through area

A(triangle)=1/2 b h      where b=6   h=9

A(triangle)=1/2 (6)(9) = 27

A(rectangle)= Lw      where L=24    h=15

A(rectangle)= (24)(15) = 360

P(triangle in rectangle)= 27/360

The value of the angles in the parallelogram are:

∠ABC = 70°

∠DCP =70°

Recall that two adjacent angles in a parallelogram add up to 180 degrees. We can say:

∠BAD + ∠ABC = 180°  (Where ∠BAD = 110°)

∠ABC = 180 - 110 = 70°

Since PC = BC, ∠BPC = 70°

Also, ∠BCP = 180 - 70 - 70 = 40° (Sum of angles in a triangle)

∠ACB = ∠BAD (opposite angles of parallelogram are equal)

Where ∠BAD = 110°

Thus, ∠ACB = 110°

∠ACB = ∠DCP + ∠BCP

110 = ∠DCP + 40

∠DCP = 110 - 40

∠DCP =70°

A recursive sequence are -20, -80, -320 and  -1280.

To write a recursive sequence that represents the sequence defined by the given explicit formula, we need to find a rule that relates each term of the sequence to the previous term.

The explicit formula for the sequence is

[tex]a_{n}[/tex] = -5 [tex](4)^{n-1}[/tex]

To find the recursive formula, we need to express each term in terms of the previous term. Let's say the first term of the sequence is  [tex]a_{1[/tex].

[tex]a_{1[/tex]  = -5 * 1 = -5

[tex]a_{2}[/tex] = -5 * 4 = -20

[tex]a_{3}[/tex] = -5 * 16 = -80

...

[tex]a_{n}[/tex] = -5 [tex](4)^{n-1}[/tex]

We can see that each term in the sequence is 4 times the previous term, so we can express the nth term in terms of the (n-1)th term as follows

[tex]a_{1[/tex] = -5

[tex]a_{n}[/tex] =  4[tex]a_{n-1}[/tex] , for n > 1

This gives us the recursive formula for the sequence. To generate the sequence, we start with the initial term [tex]a_{1[/tex] =-5 and use the recursive formula to find the subsequent terms.

For example, if we want to find a5, we can use the recursive formula

[tex]a_{2}[/tex] = 4[tex]a_{1[/tex] = 4(-5) = -20

[tex]a_{3}[/tex] =  4[tex]a_{2}[/tex] = 4(-20) = -80

[tex]a_{4}[/tex] = 4[tex]a_{3}[/tex] = 4(-80) = -320

[tex]a_{5}[/tex] = 4[tex]a_{4}[/tex] = 4(-320) = -1280

Therefore, [tex]a_{5}[/tex] = -1280.
