What set of ratio below is not equivalent to 3:4

Answer:

To find the acceleration of the object, we need to use the equation:

acceleration = (final velocity - initial velocity) / time

In this case, the initial velocity of the object was 240 m/s, the final velocity was 0 m/s, and the time was 1 minute. Plugging these values into the equation, we get:

acceleration = (0 m/s - 240 m/s) / (1 minute) = -240 m/s / 1 minute = -240 m/s^2 / 60 s = -4 m/s^2

Thus, the acceleration of the object is -4 m/s^2, which corresponds to answer choice A.

The absolute deviation of the data set 7 10 14 and 20 is 4.25.

What is the mean deviation method?

When calculating the average departure from the mean value of a particular data set, statisticians employ a measure known as the mean deviation. Following the steps below will make it simple to determine the mean deviation of the data values.

In statistics, the term "deviation" refers to the discrepancy between the observed value of a data point and its expected value. As a result, mean deviation, also known as mean absolute deviation, is the typical departure of a data point from the mean, median, or mode of the data collection.

data set is 7, 10, 14, 20,

Mean = m = 51/4 = 12.75

So the MAD is 1/4 |7-12.75| |10-12.75| |14-12.75| 20-12.75|

MAD = 17/4 = 4.25

Hence the mean absolute deviation of the data set 7 10 14 and 20 is 4.25.

Answer:

Lateral surface area of the cuboid = 84 square inch

Total surface area = 119.28 square inch

Step-by-step explanation:

Lateral surface of the cuboid = Total surface area of the cuboid - Area of the top and base of the cuboid

Total surface area = 2(lb + bh + hl) - 2(lb)

Here, l = length of the cuboid

b = width of the cuboid

h = height of the cuboid

Therefore, Lateral surface area of the given cuboid = 2(bh + hl)

= 2(2.1 × 4) + 2(4 × 8.4)

= 16.8 + 67.2

= 84 square inch

Total surface area of the cuboid = 2(8.4×2.1 + 2.1×4 + 4×8.4)

= 2(17.64 + 8.4 + 33.6)

= 2(59.64)

= 119.28 square inch

Step-by-step explanation:

The possible order pair for the point D is (0, 0.72)

Triangles with the same shape but different sizes are said to be similar triangles. Triangle resemblance is shown here by the symbol "≈"

Since triangle ABC is similar to triangle ADE, the corresponding sides of these triangles are proportional.

Let's denote the length of AB as x and the length of AD as y. Then, we can write:

AB/AD = BC/DE

Substituting the values from the figure, we get:

x/y = 5/3

Multiplying both sides by y, we get:

x = (5/3)

x = (5/3)y

Substituting x = 1.2 (the x-coordinate of point A) and solving for y, we get:

1.2 = (5/3)y

y = (3/5)(1.2)

y = 0.72

Therefore, a possible order pair for point D is (0, 0.72).

Answer:

\(y=-0.4x+8\)

Step-by-step explanation:

Let the Linear Function to represent the drip of water out of the water tank be:

\(y=mx+c\)

Where \(x\) is the time

\(y\) is the number of gallons at that time

\(m\) is the rate at which water drips

\(c\) is the initial number of gallons of water in the tank

Putting the given values in the above equation:

\(6.8 = m\times 3+c ..... (1)\)

\(4.4 =m\times 9+c..... (2)\)

Subtracting (1) from (2):

\(6m=-2.4\\\Rightarrow m =-0.4\)

Putting in equation (1):

\(6.8=-0.4\times 3+c\\\Rightarrow c = 8\)

Therefore, the linear function equation to represent in the situation is:

The two triangles n = (75 + 3) / 5 = 18. The measure of angle q is 18 degrees.

1. First, find the value of n by using the equation 5(n - 3) = 75 + 3

2. Next, add 75 and 3 together and divide by 5. This gives us a value of 18 for n.

3. Finally, use the equation 5(n - 3) to determine the measure of angle q in triangle qrs. This equals 5(18 - 3) = 5(15) = 75 degrees.

The two triangles qrs and xyz are similar, meaning they have the same angle measures. In order to find the measure of angle q in triangle qrs, we must first find the value of n. The measure of angle x in triangle xyz is 75 degrees and the measure of angle q in triangle qrs is equal to 5(n - 3) degrees. We can use this equation to solve for the value of n. To do this, we add 75 and 3, then divide by 5. This gives us a value of 18 for n. Therefore, the measure of angle q in triangle qrs is 18 degrees.

To evaluate the iterated integral ∫[2, -2] ∫[0, √(4 - x^2)] sin(x^2 + y^2) dy dx using polar coordinates, we make the following substitutions:

x = r cosθ

y = r sinθ

The limits of integration for x and y need to be expressed in terms of r and θ.

For the limits of x:

When y = 0, we have x = √(4 - x^2) and solving for x, we get x = 2.

When y = √(4 - x^2), we have x = 0.

So, the limits for x in polar coordinates are θ = 0 to θ = π.

For the limits of y:

The region of integration lies within the circle of radius 2 centered at the origin. So, the limits for y in polar coordinates are r = 0 to r = 2.

Now, we need to express the differential element dy dx in terms of polar coordinates.

dy dx = |Jacobian| dr dθ

where |Jacobian| is the determinant of the Jacobian matrix.

The Jacobian matrix is given by:

[∂y/∂r ∂y/∂θ]

[∂x/∂r ∂x/∂θ]

Calculating the partial derivatives:

∂y/∂r = sinθ

∂y/∂θ = r cosθ

∂x/∂r = cosθ

∂x/∂θ = -r sinθ

Taking the determinant of the Jacobian matrix, we have:

|Jacobian| = (∂y/∂r)(∂x/∂θ) - (∂y/∂θ)(∂x/∂r) = (sinθ)(-r sinθ) - (r cosθ)(cosθ) = -r

Now, we can rewrite the integral in polar coordinates:

∫[2, -2] ∫[0, √(4 - x^2)] sin(x^2 + y^2) dy dx

= ∫[0, π] ∫[0, 2] r sin(r^2) |Jacobian| dr dθ

= ∫[0, π] ∫[0, 2] -r^2 sin(r^2) dr dθ

Integrating with respect to r first:

∫[-r^2 sin(r^2)] [0, 2] dr = [-cos(r^2)] [0, 2] = -cos(4) + 1

Now, we can integrate the result with respect to θ:

∫[-cos(4) + 1] [0, π] dθ = [θ - cos(4)θ] [0, π] = π - πcos(4)

Therefore, the value of the iterated integral ∫[2, -2] ∫[0, √(4 - x^2)] sin(x^2 + y^2) dy dx in polar coordinates is π - πcos(4).

The function that represents the number of calories Leona burns while boxing is denoted as c(t).

To determine the function c(t) that represents the calories Leona burns while boxing, we need more information or the specific form of the function. The number of calories burned during boxing can depend on various factors such as time spent boxing, intensity, body weight, and other individual characteristics.

Commonly used formulas to estimate calories burned during physical activity involve variables such as duration and intensity. For example, one widely used formula is the Harris-Benedict equation:

c(t) = (MET * weight * t) / 24

Where:

MET represents the metabolic equivalent of the activity (specific to boxing)

weight represents Leona's body weight

t represents the duration of boxing activity in hours

However, without specific information about Leona's weight, the MET value, or any other relevant details, it is not possible to provide a specific calculation for c(t) in this format.

The function c(t) represents the number of calories Leona burns while boxing. The specific form of the function and the calculations involved depend on factors such as Leona's weight, the duration of boxing, and other variables. To determine the exact function and calculate the calories burned, specific information about Leona's circumstances and the chosen equation or method of estimation would be needed.

If you can choose one item from a group of m items and a second item from a group of n items, then the total number of two-item choices is m x n.

The total number of two-item choices that can be made when one item is chosen from a group of m items and a second item is chosen from a group of n items is given by the product of the number of choices for the first item and the number of choices for the second item.

The number of choices for the first item is m since there are m items to choose from in the first group, and the number of choices for the second item is n since there are n items to choose from in the second group.

Therefore, the total number of two-item choices is given by m x n. For example, if there are 4 items in the first group and 5 items in the second group, then the total number of two-item choices is 4 x 5 = 20.

This formula for finding the total number of two-item choices can be extended to larger groups of items as well. For instance, if there are three groups of items with sizes m, n, and p, then the total number of three-item choices is given by m x n x p.

The estimated variance of B is 0.000014 and the estimated variance of a is 26.792.

To estimate the variances of the parameter estimates in the linear regression model, we can use the following formulas:

Var(B) = (1 / [n * EX² - (EX)²]) * (EY² - 2B * EXY₁ + B² * EX²)

Var(a) = (1 / n) * (Ey? - a * EY - B * EXY₁)

Given the following values:

EX = 228

EY = 3121

EXY₁ = 38297

EX² = 3204

Exy = 3347-60

Ex? = 604-80

Ey? = 19837

n = 20

We can substitute these values into the formulas to estimate the variances.

First, let's calculate the estimate for B:

B = (n * EXY₁ - EX * EY) / (n * EX² - (EX)²)

= (20 * 38297 - 228 * 3121) / (20 * 3204 - (228)²)

= 1.331

Next, let's calculate the variance of B:

Var(B) = (1 / [n * EX² - (EX)²]) * (EY² - 2B * EXY₁ + B² * EX²)

= (1 / [20 * 3204 - (228)²]) * (3121² - 2 * 1.331 * 38297 + 1.331² * 3204)

= 0.000014

Now, let's calculate the estimate for a:

a = (EY - B * EX) / n

= (3121 - 1.331 * 228) / 20

= 56.857

Next, let's calculate the variance of a:

Var(a) = (1 / n) * (Ey? - a * EY - B * EXY₁)

= (1 / 20) * (19837 - 56.857 * 3121 - 1.331 * 38297)

x = 27

Step-by-step explanation:

A circle adds up to 360 degrees. So we make this equation:

2x+21 + 5x+6 + 54 + 90 = 360

Combine like terms:

7x + 171 = 360

Subtract both sides by 171

7x = 189

Divide both sides by 7

x = 27

Answer:

Step-by-step explanation:

this has a bunch of "implied"  things that you're supposed to know.   one is that all the way around a circle is 360°   two is that if you know the angle on the interior.. that is also the arc length.. so knowing those things  we can say

360 = 54 + 2x + 21 + 5x + 6 + 90

put like terms together

360 = 171 + 7x

189 = 7x
