The calculated values are:

a) Percentage uncertainty in D ≈ 0.329%

b) Range in the measurements of T = 0.008 s

c) Absolute uncertainty in the average value of T ≈ 0.003 s

d) Percentage uncertainty in the average value of T ≈ 0.601%

e) Percentage uncertainty in g ≈ 1.531%

f) Absolute uncertainty in g ≈ 0.150 m/s^2

To calculate the requested values, we'll follow these steps:

a) Percentage uncertainty in D:

Percentage uncertainty = (Absolute uncertainty / Measured value) * 100

Absolute uncertainty = ±0.004 m

Measured value = 1.215 m

Percentage uncertainty in D = (0.004 / 1.215) * 100 ≈ 0.329%

b) Range in the measurements of T:

Range = Maximum value - Minimum value

Range = 0.503 s - 0.495 s = 0.008 s

c) Absolute uncertainty in the average value of T:

Absolute uncertainty = Range / √(Number of measurements)

Number of measurements = 5

Absolute uncertainty in the average value of T = 0.008 s / √5 ≈ 0.003 s

d) Percentage uncertainty in the average value of T:

Percentage uncertainty = (Absolute uncertainty / Average value) * 100

Average value of T = 0.499 s

Percentage uncertainty in the average value of T = (0.003 / 0.499) * 100 ≈ 0.601%

e) Percentage uncertainty in g:

Percentage uncertainty in g = 2 * (Percentage uncertainty in T) + (Percentage uncertainty in D)

Since we have already calculated the percentage uncertainty in T and D, we can substitute the values:

Percentage uncertainty in g = 2 * 0.601% + 0.329% ≈ 1.531%

f) Absolute uncertainty in g:

Absolute uncertainty in g = Percentage uncertainty in g * g

g = 9.77 m/s^2

Absolute uncertainty in g = 1.531% * 9.77 m/s^2 ≈ 0.150 m/s^2

Step-by-step explanation:

draw a right angled triangle and use pythagoras to solve it

With reference to the image below, the transversal connecting ∠6 and ∠3 is s. Also, ∠6 and ∠3 can be classified as alternate interior angles.

The transversal is the line passing through two or more parallel lines. Here line s is passing through parallel lines p and r.  

∠6 and ∠3 both lie on line s but on different parallel lines. ∠6 lies on line p and ∠3 lies on line r. Also, ∠6 and ∠3 lie on different sides of transversal s, between the parallel lines.

When two parallel lines are crossed by a transversal, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles.

Therefore, ∠6 and ∠3 are alternate interior angles.

A word problem is just a verbal depiction of a problem situation in which one or more questions are addressed and the answers can be reached by applying mathematical operations to information (typically numerical data) in the text.

To write a word problem, consider how you would solve it and choose the best strategy for your pupils to follow. Determine the arithmetic skills you want pupils to practice on.

The problem gives us the value W, which is 740 in this example.

We may solve for T, total tablespoons, by substituting 740 into the initial equation.

The equation is now 740 = 12.5(T) + 340.

By isolating the variable T on one side of the equation, we can solve for it. To accomplish this, we must remove the other values from the equation by applying their inverse to both sides of the equation. We begin with a value that is not associated with the variable.

In this situation, it is + 340.

To get rid of this value, remove 340 from both the sides of the equation.

740 - 340 = 12.5(T) + 340 - 340.

You can see how the + 340, cancel each other out now. The equation is now 400 = 12.5 (T).

To isolate T,

400 / 12.5 = 12.5(T) / 12.5.

The right portion of the equation will now only contain the variable T, which we can identify by finishing the operation on the left side.

400 / 12.5 = 32 = T.

W = 12.5(T) + 340

740 = 12.5(T) + 340

740 - 340 = 12.5(T) + 340 - 340

400 = 12.5(T)

400 / 12.5 = 12.5(T) / 12.5

32 = T

Answer:

A = |A| = 5 units. We know, negative Y-axis is an angle 270° counterclockwise with positive X-axis. θ = Angle of vector A with positive X-axis = (270°

Step-by-step explanation:

a = 7

b = 13

c = -10

Re-writing the expression above in the form: ax² + bx + c = 0

7x² = 10 - 13x

7x² + 13x - 10 = 0

From 7x² + 13x - 10 = 0

a = 7

b = 13

c = -10

The image is located 6.7 cm behind the lens, and is 3.7 cm tall (1.34 times the height of the object).

Using the thin lens equation, we can find the position of the image formed by the lens:

1/f = 1/d0 + 1/di

where f is the focal length of the lens, d0 is the object distance (the distance between the object and the lens), and di is the image distance (the distance between the lens and the image).

Substituting the given values, we get:

1/20 = 1/5 + 1/di

Solving for di, we get:

di = 6.7 cm

This tells us that the image is formed 6.7 cm behind the lens.

To find the height of the image, we can use the magnification equation:

m = -di/d0

where m is the magnification (negative for an inverted image).

Substituting the given values, we get:

m = -(6.7 cm)/(5.0 cm) = -1.34

This tells us that the image is 1.34 times the size of the object, and is inverted.

The negative sign indicates an inverted image. Thus, the image formed is located 8.0 cm from the lens and has a height of 1.6 times that of the object, making it 4.48 cm in height.

In this scenario, an object with a height of 2.8 cm is positioned 5.0 cm in front of a converging lens with a focal length of 20 cm. To determine the location and size of the image formed by the lens, we can use the lens formula and magnification formula.

The lens formula states that 1/f = 1/v - 1/u, where f is the focal length, v is the image distance, and u is the object distance. Substituting the given values into the lens formula, we find:

1/20 = 1/v - 1/(-5.0)

Simplifying this equation yields:

1/v = 1/20 + 1/5.0

Solving for v, we obtain:

v = 8.0 cm

The positive value indicates that the image is formed on the opposite side of the lens. The magnification formula, M = -v/u, allows us to calculate the magnification of the image:

M = -8.0/-5.0 = 1.6

Answer:

45 candidates are expected to be rejected

Step-by-step explanation:

Here, we want to calculate the number of candidates to be rejected

The number of candidates to be rejected can be calculated from;

100% - (28% + 12%) = 60%

So 60% of the 75 interviewed are to be rejected

Thus, we have

60/100 * 75

= 45

The number of candidate expected to be rejected is 45 if the 12% of candidates can be selected and 28% of Canada can be put on hold for the next hiring date.

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

We have:

A walk in interview 12% of Candidates can be selected and 28% of Canada can be put on hold for the next hiring date if 75 candidates are interviewed.

Let's suppose total candidate is 100%

So,

= 100 - (12+28)

= 60%

Number of candidate expected to be rejected:

= 60% of 75

= (60×75)/100

= 45

Thus, the number of candidate expected to be rejected is 45 if the 12% of candidates can be selected and 28% of Canada can be put on hold for the next hiring date.

In the domain of finance, an R-Squared value above 0.7 is typically seen as indicating a high level of correlation, whereas one below 0.4 indicates a low level of correlation.

A statistical measure known as correlation expresses how closely two variables are related linearly (meaning they change together at a constant rate). It's a typical technique for describing straightforward connections without explicitly stating cause and consequence.

The strength of the association is measured by the sample correlation coefficient, or r. The statistical significance of correlations is also examined.

For describing straightforward links between data, correlations are helpful. Consider a dataset of campgrounds in a park in the mountains as an illustration. You're interested in finding out if the height of the campsite—how high up the mountain it is—and the summer's typical high temperature are related.
