Step-by-step explanation:

The F ratio is 1.2.

What is statistic?

The study of statistics focuses on gathering, organizing, organizing, analyzing, interpreting, and presenting data. It is customary to start with a statistical population or a statistical model to be researched when applying statistics to a scientific, industrial, or social problem.

30/25 = 1.2

In an ANOVA, this statistic is used in the F test to test the hypothesis that the group means are not equal to one another. The F ratio is calculated as follows:

Fobs=MSB/MSW

30/25 = 1.2

Where MSB is the mean square between the groups and MSW is the mean square within the groups.

Answer:

  660 in²

Step-by-step explanation:

The area of this figure looks like it is best computed by subtracting the areas of the empty corners from the area of the "bounding box."

The overall dimensions of the figure are ...

  horizontal: 31 in + 10 in = 41 in

  vertical: 13 in + 7 in = 20 in

Then the area of the bounding box is ...

  A = LW = (41 in)(20 in) = 820 in²

__

The area of the upper left empty space is ...

  A = (6 in)(5 in) = 30 in²

The area of the lower right empty space is ...

  A = (10 in)(13 in) = 130 in²

Then the area of the figure is ...

  total shaded area = (820 -30 -130) in² = 660 in²

__

Additional comment

The formula for the area of a rectangle is ...

  A = LW . . . . . . where L is the length, and W is the width

Solution:

the distance from the first plant to the last plant, ignoring the width of each plant stem, is 10.5 feet.

Why is it?

To find the distance from the first plant to the last plant, we need to add up the distances between each adjacent pair of plants. Since there are 8 plants, there are 7 pairs of adjacent plants, and each pair is separated by 1.5 feet.

So, the total distance from the first plant to the last plant is:

7 ×1.5 = 10.5 feet

Therefore, the distance from the first plant to the last plant, ignoring the width of each plant stem, is 10.5 feet.

Distance refers to the measurement of the physical space between two points or objects. It is a scalar quantity that only considers the magnitude of the separation between two points and does not take into account the direction of the separation.

Angle that the tent pole makes with the sides of the tent is 39.6°.

Trigonometric functions are defined as the real functions which are simply the functions of an angle of a triangle. They are basically the periodic functions which relate an angle in a right angled triangle to the ratios of the length of two sides.

Given that,

A conical circus tent has a 20 ft central pole that supports it. The slant height of the tent is 26 ft long.

The central pole forms a right triangle with the floor of the tent.

We need the angle tent pole makes with the sides of the tent.

We have the hypotenuse as the slant height and the central pole is the adjacent side of the angle.

The cos of the missing angle is the ratio of the length of the central pole to the length of the side of the tent.

cos x = 20 / 26 = 0.7692 ≈ 0.77

Applying arccosine,

x = cos⁻¹ (1.3) = 39.6°

Hence the required angle is 39.6°.

The required number is 400 for which 44 is 11%.

The percentage is a way to express a proportion or a fraction as a fraction of 100. It is commonly used to compare values or quantities relative to a whole or a total.

To calculate a percentage, you typically divide a part or a quantity by the whole or the total and then multiply the result by 100. The resulting value represents the percentage equivalent of the part or quantity.

It implies that a percentage value represents a certain number out of 100 parts.

Given that 44 is 11% of the number. The unknown number is calculated as,

x (11%) = 44

\(x \times \dfrac{11}{100} = 44\\x = \dfrac{44\times100}{11}\\x=400\)

According to the concept of algebraic expression and arithmetic, the correct answers are A) Number of adults = N - 25. B) Number of adults when N = 124: 124 - 25 = 99

A) Let's denote the number of children as N. Since there are 25 fewer adults than children, the number of adults can be expressed as N - 25.

B) If there are 124 children, we substitute N with 124 in the expression from part A. Thus, the number of adults would be 124 - 25 = 99.

To arrive at these answers, we used the given information that there are "N" children and 25 fewer adults than children. By substituting the value of N, we determined the number of adults in terms of N and then calculated the specific number of adults when N is equal to 124.

Note: The given question is incomplete. The complete question is:

Answer:

The rectangle is 5 inches long by 19 inches wide.

Step-by-step explanation:

Let's start by listing what we know:

Let's represent the width with "w" and length with "l", and make a system of equations based on what we know.

\(\left \{ {{2w + 2l = 48} \atop {w = 3l + 4}} \right.\)

Now, let's solve the system of equations using substitution:

\(2w + 2l = 48\)

\(2 (3l + 4) + 2l = 48\)

\(6l + 8 + 2l = 48\)

\(8l + 8 = 48\)

\(8l = 40\)

\(l = 5\)

The length of the rectangle is 5 inches.

Now, let's use this to solve for the width.

\(w = 3l + 4\)

\(w = 3(5) + 4\)

\(w = 15 + 4\)

\(w = 19\)

The width of the rectangle is 19 inches.

Let's check our work:

\(2w + 2l = 48\)

\(2(19) + 2(5) = 48\)

\(38 + 10 = 48\)

\(48 = 48\)

The results match, so our answer is correct.

The rectangle is 5 inches long by 19 inches wide.

To find the length of AB, we can use the property that two tangents to a circle from the same external point are equal. This means that AB = AD. Substituting the given values, we get:

8x = x + 9

Solving for x, we get:

x = 1.5

Therefore, AB = 8x = 8(1.5) = 12.

To check our answer, we can use the Pythagorean theorem on triangle ABD, since AB is perpendicular to BD at the point of tangency. We have:

AB^2 + BD^2 = AD^2

Substituting the values, we get:

12^2 + BD^2 = (1.5 + 9)^2

Simplifying, we get:

BD^2 = 56.25

Taking the square root of both sides, we get:

BD = 7.5

Hence, the length of AB is 12 and the length of BD is 7.5.

Answer:

0.253 m/s

Step-by-step explanation:

radius r of the circular rise = 13 mm = 0.013 m

apparent weight loss = 50%

acceleration of the new weight = 0.5 x 9.81 = 4.905 m/s^2

centripetal acceleration = 9.81 -  4.905 =  4.905 m/s^2

centripetal acceleration = \(\frac{v^{2} }{r}\)

where v is the acceleration at the rise and r is the radius of the rise

centripetal force = \(\frac{v^{2} }{r}\)  = \(\frac{v^{2} }{0.013}\)

4.905 = \(\frac{v^{2} }{0.013}\)

\(v^{2}\) = 0.063765

v = \(\sqrt{0.063765}\) = 0.253 m/s
