Answer: 30 sq ft

Step-by-step explanation:

Let's calculate the area of both rooms.

John's room is 12x8 ft, so we can multiply to get the area. 12x8=96 ft squared.

Spencer's room is 14x9 ft, so we will do the same thing. 14x9= 126 ft squared.

Now, we can subtract 96 from 126 to find out how much larger Spencer's room is. 126-96= 30 ft squared.

This hypothesis test is testing the proportion of commuting students who walk to school.

Hence, you perform a one-sample proportion test.

The alternative hypothesis has a "less than" symbol in it and both of the hypotheses compare the parameter to the value 0.5.

The value of your test statistic is -1.885, which results in a p-value of 0.030.

You could also find the critical value, which is -1.645.

Using the p-value or the critical value, you determine that you reject the null hypothesis.

This means that there is significant evidence to say that the proportion of commuting students that walk is less than half at the 10% level of significance.

A histogram is a graphical representation of the tonal range of an image. It shows how many pixels are found in an image for each tonal value.

Tonal values run from black on the left side of the histogram to white on the right side. In this case, if the peaks of the histogram are on the left side, then the photographer can deduce that the image is underexposed. This implies that the camera's exposure settings were not correctly calibrated or that there was a lack of light in the environment. When the peaks of the histogram are located on the left side, the image will have a lack of brightness and detail in the shadows.

A landscape photographer should be familiar with histograms and how they function to capture the ideal shot. A histogram is a graphical representation of the tonal range of an image. It shows how many pixels are found in an image for each tonal value. Tonal values run from black on the left side of the histogram to white on the right side. An ideal histogram should have tonal values distributed uniformly across the tonal range. However, if the peaks of the histogram are on the left side, then the image is underexposed. This implies that the camera's exposure settings were not correctly calibrated or that there was a lack of light in the environment.The underexposed image appears darker and lacking in detail in the shadows, which are important for landscape photography. To correct this issue, the photographer should adjust the camera's exposure settings or add more light to the scene, or both. The photographer could increase the ISO value, use a larger aperture, or slow down the shutter speed to fix the exposure. The goal is to reposition the peaks to the center of the histogram or as close as possible to the center of the histogram. Correcting the exposure settings will result in a well-balanced histogram that includes detail in the highlights and shadows.

If the histogram's peaks are on the left side, the image is underexposed. Adjusting the camera's exposure settings or increasing the amount of light in the scene will help the photographer obtain a properly exposed image with a balanced histogram.

There are two ways to fence the garden in 3 areas with some equal sections.

2/5, 2/5, 1/5 and 3/5, 1/5, 1/5.

Fraction definition

A fraction depicts a segment or component of the whole. It represents the equal parts that make up the whole. A fraction is made up of two parts: the numerator and the denominator. The number at the top is the numerator, and the number at the bottom is the denominator. The denominator specifies the total number of equal parts in the whole, whereas the numerator specifies the number of equal parts that are taken.

Given The garden is divided into 5 equal pieces, each of which is 1/5 of the total garden size.

By arranging some equal parts together, she will fence the garden into three sections. There are two ways to do this.

(1/5 +1/5) = 2/5

(1/5 +1/5) = 2/5

1/5

these are the 3 areas 2/5, 2/5, 1/5.

and

(1/5 +1/5 + 1/5) = 3/5

1/5, 1/5

these are 3 areas =  3/5, 1/5, 1/5.

Hence there are only two ways to fence the garden into three areas by grouping some equal sections.

When you are given two sides but no measurement of the angle, such as a = 15 and b = 15, we can create an infinite number of triangles.

For instance:

How many different triangles can be made if we have side lengths of 15 and 15 and an angle value of 0 to 360 degrees?

Using a protractor, make one of the triangles with sides of 25 metres and 21 metres, an angle of 12 degrees, and a third side that can be changed to your preferred length. You've constructed a triangle.

Similar to this, we can create a completely different triangle by varying the third side's length and angle measurement.

It's crucial to remember that you select the side lengths and angle. This implies that you might choose differently. You may create an infinite number of distinct triangles by using the same angles.

As a result, we can make an infinite number of triangles using just one angle and one side length.

Answer: B

The Vertical Angles Theorem states that vertical angles, angles that are opposite each other and formed by two intersecting straight lines, are congruent. This means that 48° should equal (7x+13)°, because they're vertical angles. The equation should appear as 48=7x+13. Subtract 13 on both sides to get. 35=7x. Divide 7 on both sides to result with x=5.

1) Average velocity = (254x + 0.5y - 6.5x - 5y) / 9s.

2) Instantaneous velocity at t=0.5s: v = 2.5x - 20y, angle with positive x-axis ≈ -80.54 degrees.

3) Acceleration = 5.25\(m/s^2\), final velocity = 10.27 m/s.

1) The average velocity during the interval t=1s to t=10s can be found by calculating the displacement over that time interval and dividing it by the duration. The displacement is given by r(10s) - r(1s):

\(r(10s) = (4.0 + 2.5(10^2))x + (5/10)y = 254x + 0.5y\)

\(r(1s) = (4.0 + 2.5(1^2))x + (5/1)y = 6.5x + 5y\)

Average velocity = (r(10s) - r(1s)) / (10s - 1s) = (254x + 0.5y - 6.5x - 5y) / 9s

2) The instantaneous velocity at t=0.5s can be found by taking the derivative of the displacement vector with respect to time and evaluating it at t=0.5s:

\(v(t) = d(r(t))/dt = (d(4.0 + 2.5t^2)/dt)x + (d(5/t)/dt)y\)

     \(= (5t)x - (5/t^2)y\)

\(v(0.5s) = (5(0.5))x - (5/(0.5)^2)y = 2.5x - 20y\)

The angle that the velocity vector makes with the positive x-axis can be found using the arctan function:

θ = arctan(vy/vx) = arctan((-20)/(2.5)) = arctan(-8) ≈ -80.54 degrees

3) The acceleration down the ramp can be determined using the formula:

\(a = g sin(θ) = 9.8 m/s^2 * sin(33 degrees) ≈ 5.25 m/s^2\)

The final velocity once it reaches the bottom of the ramp can be found using the equation of motion:

\(v^2 = u^2 + 2as\)

Assuming the ball starts from rest (u = 0), the final velocity is given by:

v = sqrt(2as) = sqrt(2 * 5.25 * 10) ≈ 10.27 m/s

Therefore, the acceleration down the ramp is approximately 5.25 m/s^2 and the final velocity at the bottom is approximately 10.27 m/s.

Answer:

By an online search, I've found that the dimensions of the eraser are:

4cm by 2cm by 0.5cm

First, we need to remember that for a rectangular prism of length L, width W, and height H, the volume is:

V = L*W*H

We know that the measures of the box are:

12cm by 20cm by 5cm

Then we can define:

L = 12cm

W = 20cm

H = 5cm

Then the total volume of the box is:

V = 12cm*20cm*5cm = 1200 cm^3

For the eraser, we will have:

L = 4cm

W = 2cm

H = 0.5cm

Then the volume of the eraser is:

v = 4cm*2cm*0.5cm = 4 cm^3

The volume of the box that is not taken up by the eraser is equal to the difference between the volume of the box and the volume of the eraser.

Then:

Volume not taken by the eraser = V - v = 1200cm^3 - 4cm^3 = 1196cm^3
