A repeated-measures experiment comparing two treatment conditions, the t statistic has a df of 31. 32 subjects participated in this study.

A matched-subjects experiment produced a t statistic with a df of 17.

34 subjects participated in this study.

Both a repeated-measures experiment and a matched-subjects experiment share the following characteristics when used to compare two treatment conditions:

1. They both use the same t statistic.
2. The researcher computes difference scores to compute a t statistic.
3. The researcher must compute an estimated standard error for the mean difference score to compute a t statistic.

For a repeated-measures experiment comparing two treatment conditions, the t statistic has a df of 31.

The number of subjects that participated in this study is 32 because the degrees of freedom (df) for a repeated measures experiment is calculated as (number of subjects - 1),

so 31 + 1 = 32.

A matched-subjects experiment produced a t statistic with a df of 17.

In this case,

the number of subjects that participated in the study is 34 because the degrees of freedom (df) for a matched-subjects experiment is calculated as (number of pairs - 1),

since there are two subjects in each pair, 17 + 1 = 18 pairs, which means 18 * 2 = 34 subjects.

The area of the rectangle is 31/3 square centimeters or 10 1/3 square centimeters as a mixed number.

To find the area of the rectangle, we need to multiply its length by its width.

First, we need to convert the mixed numbers to improper fractions:

Length = 5 1/6 cm = (6 × 5 + 1)/6 = 31/6 cm

Width = 2 2/7 cm = (7 × 2 + 2)/7 = 16/7 cm

Now, we can multiply the two fractions to get the area of the rectangle:

Area = length × width

= (31/6 cm) × (16/7 cm)

= (31 × 16) / (6 × 7) cm²

= 496/42 cm²

= 248/21 cm²

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor (GCF), which is 8:

248/21 cm² = (8 × 31)/ (8 × 3) cm²

= 31/3 cm²

= 10 1/3 cm²

Step-by-step explanation:

Answer:∠A = 9

Step-by-step explanation:In a Parallelogram opposite angles are always equal thus,  14x - 4 = 15x - 13.

Start by isolating the variable on one side of the equation. You can do this by subtracting 14x from both sides:

14x - 4 - 14x = 15x - 13 - 14x

Simplifying the left side gives:

-4 = x - 13

Now, isolate x by adding 13 to both sides:

-4 + 13 = x - 13 + 13

Simplifying the left side gives:

9 = x

Therefore, the solution to the equation 14x - 4 = 15x - 13 is x = 9

The ordered pair that represents the location of vertex A after the dilation is (8, 20).

Vertex is a point in geometry that describes the location of a object in a two-dimensional or three-dimensional space. In two-dimensional space, it is a point where two lines, curves, or surfaces intersect. In three-dimensional space, it is the point where three planes intersect. In a graph, it is the point where two lines intersect.

Vertex A of the original kite is located at (6, 15).
The center of dilation is at (1, 1). To dilate the kite by a scale factor of 4/3, each point (x,y) of the kite must be multiplied by the scale factor, 4/3. In this case, vertex A will transform to (8, 20) after the dilation.

The popcorn container can hold 432 cubic inches of popcorn.First, we need to find the volume of the popcorn container. The formula for the volume of a square pyramid is:

Volume = (1/3) * base area * height

To find the base area, we need to first find the area of one of the square sides. Since each side measures 6 inches, the area of one square side is:

Area = side length^2 = 6^2 = 36 square inches

Since the popcorn container is a square pyramid, it has four identical square sides, so the total base area is:

Base area = 4 * 36 square inches = 144 square inches

Now we can plug in the values for the base area and height into the formula for volume:

Volume = (1/3) * 144 square inches * 9 inches

Volume = 432 cubic inches

So the popcorn container can hold 432 cubic inches of popcorn.

Answer:

Step-by-step explanation:

The sine model is y=10 sin(1/30 t) + 30.  The 30 represents default distance from the ground, and the ten is required to represent the length of the blades.  Every 30 seconds, one rotation completes, so t must be multiplied by 1/30.

The differential equation with initial conditions describing the motion is F = -k * (s(t) + 5) - 6g and the displacement of the mass from its equilibrium position as a function of time s(t) = (3 * r2 * e^(r1*t)) / (r2 - r1) + (3 * r1 * e^(r2*t)) / (r1 - r2)

The differential equation for the motion of the mass is given by Newton's Second Law, F = ma:

F = -k * (s(t) + 5) - 6g

where k is the spring constant, s(t) is the displacement from the equilibrium position, and g is the acceleration due to gravity. The initial conditions are s(0) = 3 and s'(0) = 0, since the spring is initially stretched an additional 3 cm and released from rest.

We can rearrange the equation to get:

s''(t) + (k/6) * s(t) = -5k/6 - g

This is a second-order linear homogeneous differential equation with constant coefficients. The general solution is:

s(t) = C1 * e^(r1*t) + C2 * e^(r2*t)

where r1 and r2 are the roots of the characteristic equation:

r^2 + (k/6) * r = -5k/6 - g

Using the quadratic formula, we get:

r1,2 = -(k/12) ± √((k/12)^2 + 5k/6 + g)

We can find the values of C1 and C2 by applying the initial conditions:

s(0) = C1 + C2 = 3

s'(0) = C1 * r1 + C2 * r2 = 0

Solving for C1 and C2, we get:

C1 = (3 * r2) / (r2 - r1)

C2 = (3 * r1) / (r1 - r2)

Substituting back into the general solution, we get:

s(t) = (3 * r2 * e^(r1*t)) / (r2 - r1) + (3 * r1 * e^(r2*t)) / (r1 - r2)

This is the displacement of the mass from its equilibrium position as a function of time.

The fraction of the material that each strip represents is 1/12 of a yard.

Susan bought 1/3 of a yard of material to use for the border for the blanket. She cut the material into 4 same-size strips. The problem is asking for the part of a whole yard that each strip represents.

Since Susan has 1/3 of a yard of material and she cut it into 4 same-size strips, we can use division to find the fraction of the material that each strip represents.

Therefore, the fraction of the material that each strip represents is 1/3 ÷ 4.

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.

The reciprocal of 4 is 1/4, so we can rewrite the expression as:

1/3 ÷ 4 = 1/3 × 1/4

Now we can multiply the fractions:

1/3 × 1/4 = 1/12

To round to the nearest tenth, we can say that a cell phone's battery life is typically 2 hours after two years.

Generally speaking, the battery life of a cell phone will depend on the type of phone and usage habits. Most cell phones will last about 18-24 months before needing to be replaced.

The battery life of a cell phone is determined by a variety of factors, including battery capacity, phone usage habits, and battery age. We can, however, make certain assumptions and calculate how long it would take for a common mobile phone battery to decline to 2 hours of battery life.

Considering that a typical lithium-ion battery, which is often used in mobile phones, has a capacity of approximately 3,000 mAh when new and that its capacity drops by roughly 20% after 2-3 years of usage, we may estimate that the battery capacity would be around 2,400 mAh after 2-3 years.

Yes, the political party can conclude that the Hispanic proportion of the population has changed since 2010

Now, let's look at the given information. In 2010, the percentage of Hispanic or Latino people in Oregon was 11.7%. This means that out of every 100 people in Oregon, approximately 12 were Hispanic or Latino.

The political party conducted a survey of 853 adults in Oregon and found that 113 of them were Hispanic or Latino. To determine if the percentage of Hispanic or Latino people in Oregon has changed since 2010, we need to compare the survey results to the 2010 percentage.

To do this, we can calculate the percentage of Hispanic or Latino people in the survey by dividing the number of Hispanic or Latino people in the survey (113) by the total number of people surveyed (853), and then multiplying by 100. This gives us a percentage of approximately 13.2%.

Using this formula, we can estimate the margin of error for this survey to be approximately +/- 2.8%.

This means that the true percentage of Hispanic or Latino people in Oregon could be as low as 10.4% or as high as 15.6%, based on the survey results.

Since the margin of error includes the 2010 percentage of 11.7%, we cannot conclude that the Hispanic proportion of the population has definitively changed based on this survey alone.

Factored completely:

2x2(−x−2)(x−7)

Step-by-step explanation:

The transformation used to create the graph of g(x) from the graph of f(x) is a vertical and horizontal transformation.

The "-2" in the equation of g(x) reflects a vertical stretch by a factor of 2, which causes the graph to become narrower and steeper than f(x).

The "+6" in the equation of g(x) reflects a vertical shift upward by 6 units, which moves the entire graph of g(x) upward by 6 units.

Therefore, the transformation used to create the graph of g(x) from the graph of f(x) is a vertical and horizontal transformation.

The length of the corresponding side of the larger polygon is 5/4.

What is polygon?

A polygon is a two-dimensional shape that is formed by connecting a sequence of straight lines (called sides or edges) end-to-end to form a closed loop. The term "poly" means "many," and "gon" means "angle," so a polygon literally means "many angles."

Polygons can have any number of sides, from three (a triangle) to infinity. The most common polygons are the quadrilateral (four sides), pentagon (five sides), hexagon (six sides), heptagon (seven sides), octagon (eight sides), nonagon (nine sides), and decagon (ten sides).

Let's assume that the smaller polygon has n sides and the larger polygon has m sides. Since the polygons are similar, their corresponding sides are proportional. Therefore, we can set up the following proportion:

n/m = 4/x

where x is the length of the corresponding side of the larger polygon.

We also know that the perimeter of the smaller polygon is 20, so each of its sides has length 20/n. Similarly, the perimeter of the larger polygon is 28, so each of its sides has length 28/m.

Since the polygons are similar, their corresponding sides are proportional, so we can set up another proportion:

(20/n) / (28/m) = 4/x

Simplifying this expression, we get:

20m = 28nx

Dividing both sides by 4, we get:

5m = 7nx

Substituting n/m = 4/x, we get:

5m = 28x

Solving for x, we get:

x = (5m)/28

Now, we need to find the value of m. The perimeter of the smaller polygon is 20, so the sum of its sides is 20. Since each side has length 20/n, we can write:

20 = (20/n)*n

Simplifying, we get:

n = 4

The perimeter of the larger polygon is 28, so the sum of its sides is 28. Since each side has length 28/m, we can write:

28 = (28/m)*m

Simplifying, we get:

m = 7

Now, we can substitute the value of m into the expression for x that we derived earlier:

x = (5m)/28 = (5*7)/28 = 5/4

Therefore, the length of the corresponding side of the larger polygon is 5/4.
