Answer: Yes Leah Is Correct.

Step-by-step explanation: Leah is correct because if you have a rectangle divided into 4 parts than if you will be asked how much parts will you need to make this fraction a whole you’ll say 4 since if you say for example six you will be wrong since six is too much so if you shade one part in than it’s 1/4 ths now let’s say you shaded in 3/4th you will see 3 shaded and one more left not shaded in which gives the fraction the name 3/4.

The transformation from the graph of F to the graph of G involves a horizontal translation to the right by h units, followed by a vertical translation down by 3 units.

What is transformation?

In mathematics, a transformation refers to a function that maps points or shapes in one geometric space to points or shapes in another geometric space. Transformations include operations such as translation, rotation, reflection, dilation, and others, and are commonly used in geometry, algebra, and other branches of mathematics to study and analyze various properties of shapes, functions, and equations. Transformations can be described using algebraic notation, matrices, or graphical representations, and are often used in practical applications such as computer graphics, engineering, and physics.


According to the question:
The transformation from the graph of F to the graph of G can be described as a horizontal translation to the right by h units, followed by a vertical translation down by 3 units.

Specifically, the function f(x) =\(\sqrt(x) - 3\) can be thought of as starting with the parent function \(f(x) = \sqrt(x)\)and shifting it down by 3 units.

Then, when we apply the transformation g(x) = f(x - h), we shift the graph of f(x) to the right by h units. This means that the point (h, 0) on the graph of f(x) will now be at the origin, and the point (h+1, 1) on the graph of f(x) will now be at (1, 1) on the graph of g(x).

So overall, the transformation from the graph of F to the graph of G involves a horizontal translation to the right by h units, followed by a vertical translation down by 3 units.

The download rate per minute is 7 megabyte per minute.

A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. This is not a ratio of two like units, such as shirts. This is a ratio of two unlike units: cents and ounces.

download rate /minute = change in megabytes/change in time

change in megabytes = 215-5 = 210megabytes

change in time = 1:30pm - 1:00 pm

= 30minutes

the download rate per time = 210/30

= 7megabytes per minute

The given statement, "We can use the normal distribution to approximate the sampling distribution of the average (\(\bar X\)) for a small sample (n<30) even if our sample has clear outliers." is false.

Several random samples of a predetermined size are taken from the same population to generate a sampling distribution, which is a sort of probability distribution. You can better understand how a sample statistic fluctuates from sample to sample by using these distributions.

The given statement is false because when the sample size is small (n < 30) and the data have clear outliers, the normal distribution may not be a suitable approximation for the sampling distribution of the average (\(\bar X\)). In such cases, the presence of outliers can significantly affect the distribution, causing it to deviate from a normal distribution.

For small samples with outliers, it is generally recommended to use alternative methods or non-parametric tests that do not assume a specific distribution. These methods take into account the non-normal nature of the data and provide more robust and reliable results.

Thus, the height of the water in the tank is increasing at a rate of approximately 4 / (9π) meters per minute

To solve this problem, we need to find the rate at which the height of the water is increasing. Let's call the height of the water in the tank h(t), and the rate at which it is increasing dh/dt. We know that the volume of a cylinder is given by the formula\( V = πr^2h\), where V is the volume, r is the radius, and h is the height.
Given information:
- The radius of the cylindrical tank, r, is 3 m.
- The volume of water, V, is being filled at a rate of 4 m^3/min.
We want to find dh/dt. First, we need to find the expression for the volume of the water in the tank with respect to time, V(t):
V(t) = π(3)^2*h(t)
V(t) = 9π*h(t)
Now, we can find the derivative of V(t) with respect to time:
dV/dt = 9π*dh/dt
We know that dV/dt = 4 m^3/min. Therefore:
4 = 9π*dh/dt
Now, we can solve for dh/dt:
dh/dt = 4 / (9π)

Given that three charges (-25 nC, 79.1nC, and −55.9nC) are placed at three of the four corners of a square with sides of length 22.2 cm. We need to determine the value of the electric potential (in V) at the empty comer if the positive charge is placed in the opposite corner.

The formula for the electric potential at a point in space is given by;V = k [ (q1 / r1) + (q2 / r2) + (q3 / r3) + ….. ]where;k = Coulomb's constant (8.99 × 10^9 Nm²/C²)q1, q2, q3,…. are the charges at the cornersr1, r2, r3,…. are the distances from the corner to the point whose potential is being calculated Now we can calculate the electric potential at the empty corner as follows;The three charges can be represented as shown below:Charges at corners of a square

The distance from any corner to the opposite corner (where the positive charge is placed) is given by d = √[ (22.2 cm)² + (22.2 cm)² ] = 31.4 cmTherefore, the electric potential at the empty corner is given by;V = k [ (q1 / r1) + (q2 / r2) + (q3 / r3) ]Here, q1 = -25 nC, q2 = -55.9 nC, q3 = 79.1 nC, r1 = r2 = r3 = d = 31.4 cm = 0.314 mPlugging in the values we get;V = 8.99 × 10^9 [ (-25 × 10^-9 / 0.314) + (-55.9 × 10^-9 / 0.314) + (79.1 × 10^-9 / 0.314) ]= 8.99 × 10^9 [ -0.0795 - 0.1783 + 0.252 ]= 8.99 × 10^9 × 0.0052= 46.8 VTherefore, the value of the electric potential at the empty comer if the positive charge is placed in the opposite comer is 46.8 V.

Answer:

Step-by-step explanation:

Let's say we have a for pounds of almonds and c for pounds of cashews.

6.5a + 5.5c = 23.5

6.5 * 1.5 + 5.5c = 23.5

9.75 + 5.5c = 23.5

5.5c = 13.75

c = 2.5

So, Ariel bought 2.5 pounds of cashews.

Hope this helps!

Answer:

2.5 pounds of cashews

Step-by-step explanation:

First, we have to find out how much money she spent on almonds. To do this we must multiply how many pounds she got by the price per pound. This means we multiply $6.5 by 1.5, which equals $9.75. Now we have to subtract this from the total amount she spent to find how much she spent on cashews. Since $23.50-$9.75=$13.75, she spent $13.75 on cashews. Now all we have to do is divide this by how much it cost per pound to find out how many pounds she bought. Since 13.75/5.5=2.5, she bought 2.5 pounds of cashews.

Thus, the wind speed at 80 meters is approximately 8.74 m/s when the wind speed at 60 meters is 8 m/s and the shear exponent is 1/7.

In order to find the wind speed at 80 meters, we need to use the shear exponent. The industry standard for the shear exponent is 1/7, which means that the wind speed will decrease by a factor of 1/7 for every meter increase in height.

To calculate the wind speed at 80 meters, we can use the following formula:

Wind speed at 80m = Wind speed at 60m * (80/60)^(1/7)

Plugging in the given values, we get:

Wind speed at 80m = 8 * (80/60)^(1/7)
Wind speed at 80m = 8 * 1.092
Wind speed at 80m = 8.74 m/s

Therefore, the wind speed at 80 meters is approximately 8.74 m/s when the wind speed at 60 meters is 8 m/s and the shear exponent is 1/7.

It's important to note that the shear exponent can vary depending on the atmospheric conditions, terrain, and other factors. So, this calculation provides an estimate based on the given standard.

Barbecue sauce was in the full bottle is 30 ounces and he use the second time is 4.5 ounces.

Given:

Tyler uses 7.5 ounces of barbecue sauce from a full bottle ,he estimates that he used about 25% of the barbecue sauce in the bottle.

25% = 7.5

multiply by 4 on both sides

25%*4 = 7.5 * 4

100% = 75/10 * 4

= 300/10

Full bottle = 30 ounces.

b.

Tyler uses 20% of the remaining barbecue sauce.

Remaining sauce = 30 - 7.5

= 22.5

= 22.5*20/100

The perimeter of the triangle can be found by adding the length of the three sides of the triangle.

Each side length is \(2\frac{1}{4}\) .

So, the total perimeter is:

\(\text{P}=2\frac{1}{4}+2\frac{1}{4}+2\frac{1}{4}\)
