An F statistic is “A ratio of two variances”

A test for comparing “variances” or “standard deviations” from two populations is done by F-test statistic.

The "F-statistic" is calculated using the formula,

F-statistic= \(S1^2/S2^2,\)

where the ‘degrees of freedom’ for the denominator are df2 = n2 - 1 and the ‘degrees of freedom’ for the numerator are df1 = n1 - 1.

Therefore, the ‘F-statistic’ is the ratio of two variances.

The F-statistic cannot be “difference between three means”, “A ratio of two means”, and “A population parameter

Applying the inscribed angle theorem, we have:

9. B. m∠ABC = 70°

10. F. m∠Z = 54°

11. According to the two-tangent theorem, x is: D. 8 m

An inscribed angle in a circle has a measure that is half of the measure of the intercepted arc, based on the inscribed angle theorem.

The two-tangent theorem states that if two tangents are drawn from a circle to meet at a point outside the circle, the two tangents are equal to each other.

9. Measure of arc AC = 360 - 120 - 100

Measure of arc AC = 140°

m∠ABC = 1/2(measure of arc AC) [inscribed angle theorem]

m∠ABC = 1/2(140)

m∠ABC = 70° [option B]

10. Arc XYZ = 2(m∠X) [inscribed angle theorem]

Arc XYZ = 2(126) = 252°

Arc WXY = 360 - arc XYZ

Arc WXY = 360 - 252

Arc WXY = 108°

Answer:

  gh280,854

Step-by-step explanation:

You want the total income after 3 and half years of a man and a woman who receive a monthly salary of gh3725 and gh2962 respectively.

You can add up the income from each of the months for each of them, or you can use multiplication to simplify the problem.

The total income each month is ...

  gh3725 +gh2962 = gh6687

The total received in 42 months is ...

  42 × gh6687 = gh280,854

Their total income after 3 1/2 years is gh280,854.

The sequence of the energy conversion is;  Kinetic → electrical → light Option A

From the first law of thermodynamics, we know that energy can neither be created nor destroyed but it can be converted from one form to the other. We have been told that in this case, the flashlight shown below has no batteries. Instead, it is operated by squeezing and letting go of the handle.

The letting go of the handle is kinetic energy which would lead to electrical energy that is then converted into the visible light energy.

The weight of the book is 870 grams.

To determine the weight of the book using the pan balance and metric weights, we need to consider the masses of the weights used and their corresponding values. In this case, Keyon used one 500-gram weight, three 100-gram weights, and seven 10-gram weights.

The 500-gram weight has a mass of 500 grams. This weight alone contributes 500 grams to the total mass measured by the pan balance.

The three 100-gram weights have a total mass of 3 * 100 = 300 grams. These weights add an additional 300 grams to the total mass.

The seven 10-gram weights have a total mass of 7 * 10 = 70 grams. These weights contribute 70 grams to the overall mass measured by the pan balance.

To calculate the total mass indicated by the pan balance, we add up the masses of all the weights used:

Total mass = 500 grams + 300 grams + 70 grams

Total mass = 870 grams

Therefore, the weight of the book is 870 grams.

It's important to note that the pan balance and metric weights provide a means to measure the mass of objects. By using different combinations of weights and observing the balance, one can determine the relative mass of the object being weighed. The accuracy of the measurement depends on the precision of the weights and the calibration of the pan balance.

Population growth rate of the bacterial culture can be expressed as a function of time as N = \(e^{kt + C}\)

Step-by-step explanation:

If we assume the number of bacteria at any time (t) is (N). Then, the population of bacterial culture at that time is given by

N = N (t)

It is also given that the rate at which the bacterial culture will grow is proportional to its size. So, the growth rate is given by

dN/dt ∝ N

Removing the sign of proportionality, we get a constant

dN/dt = KN

We get

∫1/N dt = ∫K dt

After integration

ln N = Kt + C

N = \(e^{kt + C}\)

To evaluate \(8^{\frac{2}{3} }\) first find the square of 8 and then take the cube root.

The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself.

Depending on the powers they possess, many rules of exponents are given.

Law of Multiplication: Exponents should be added while keeping the base constant when multiplying like bases.

Exponents should be multiplied while bases are kept constant when bases are raised by a power of two or more.

Division Rule: When dividing like bases, maintain the base constant and deduct the exponent of the denominator from the exponent of the numerator.

The given value can be written as:

\(8^{\frac{2}{3} } = \sqrt[3]{8^{2} }\)

Hence, to evaluate \(8^{\frac{2}{3} }\) first find the square of 8 and then take the cube root.

Step-by-step explanation:

calculator..

The volume of water remain in the tank after 30 seconds is 78.75 liters.

The given parameters;

The amount of water drained after 30 seconds is calculated as follows;

\(V_1 =2.5 \ \frac{liters}{\min} \times \frac{1 \min}{60 \ s} \times 30 \ s\\\\V_1 = 1.25 \ liters\)

The volume of water remain in the tank after 30 seconds is calculated as follows;

V₂ = V₀ - V₁

V₂ = 80 liters - 1.25 liters

V₂ = 78.75 liters

Thus, the volume of water remain in the tank after 30 seconds is 78.75 liters.

The proportionality used in the given diagram is 4/3=12/x if ΔABC and ΔDEF are similar. So, option 4 is correct.

Triangles are polygons because they have three vertices and three edges. This is one of the basic shapes in geometry.

In Euclidean geometry, any three non-collinear points determine a distinct triangle and a distinct plane (i.e. a two-dimensional Euclidean space). To put it another way, every triangle has a plane that it is contained in, and there is only one plane that contains every triangle. If and only if all geometry is the Euclidean plane, all triangles are contained in a single plane; however, this is no longer true in higher-dimensional Euclidean spaces. The topic of this article, unless otherwise stated, is triangles in Euclidean geometry, specifically the Euclidean plane.

We have to assume that ΔABC and ΔDEF are similar.

If the triangles are similar,

Then the proportionality is:

AB/BC=DE/EF

4/3=12/x

Therefore, the proportionality used in the given diagram is 4/3=12/x.

Answer:

y = 150º

Step-by-step explanation:

The sum of internal angles of a triangle must be 180º and the sum of y + (x-20) forms a straight line which is also 180º, so:

2x + x + (x - 20) = 180

4x - 20 = 180

4x = 200

x = 50

x - 20 = 50 - 20

x - 20 = 30

y = 180 - 30

y = 150º

All three parts of the given problem regarding trails, paths and walks have been solved below.

A path is defined as a way in which we can traverse the graph such that neither vertices nor the edges are repeated. In the given graph we can see that for going from a to c there are 4 ways that satisfy the condition of a path. A Trail is an open walk in which no edge is repeated but the vertex can be repeated. So, in the given graph we can see that there are 3!(4) ways in which we can go from a to b and then c and 4 paths in which we can go directly from a to c.

The walk is a sequence of vertices and edges of a graph that can be closed if we come to the same point after traversing the graph or open if we go from one point to another. In the given graph since we go from a point to c point the walk is open but the length of edges of the walk is not defined so if we take the no. of edge length to be 4

there can be 44 ways

so,

number of paths from a to c = 4

number of trails from a to c = 4+3!(4)= 28

number of paths from a to c = 4+3!(4)+2!(6)+1!(4)= 44
