The number of non-working light bulbs that would be expected in the group of 1,000 light bulbs is: 50 bulbs

In survey sampling, the term probability of selection is one that refers to the chance (i.e. the probability from 0 to 1) that a member (element) of a population can be chosen for a given survey.

We are told that a sample of 40 bulbs were picked from a box of 1000 bulbs and it was discovered that 2 of the bulbs were not working. Thus:

Fraction of bulbs not working = 2/40 = 0.05

Thus, number of bulbs not working in a sample of 1000 bulbs is:

0.05 * 1000 = 50 bulbs

Based on the information provided dilate triangle ABC by a scale factor of 3, with point D as the center of dilation.

To perform a dilation, each point in the original figure is transformed by multiplying its coordinates by the scale factor and then translating the figure according to the center of dilation. In this case, each point in triangle ABC will be multiplied by a scale factor of 3, with point D as the center of dilation.

To dilate the triangle by a scale factor of 3, you can follow these steps

Hence,  if the scale factor is greater than 1, the dilated figure will be larger than the original. If the scale factor is between 0 and 1, the dilated figure will be smaller than the original. If the scale factor is negative, the figure will be reflected across the center of dilation.

The numeric values of the piecewise function in this problem are given as follows:

To calculate the numeric value of a function or of an expression, we substitute each instance of any variable or unknown on the function by the value at which we want to find the numeric value of the function or of the expression presented in the context of a problem.

A piecewise function is a function that has different definitions, based on the input x of the function.

For values of x that are of 1 or less, the function is defined as follows:

f(x) = x.

Hence the numeric values in this interval are given as follows:

For values of x that are greater than 1, the function is defined as follows:

f(x) = -x + 4.

Hence, at x = 3, the numeric value of the function is given as follows:

f(3) = -3 + 4 = 1.

The distributive property of multiplication can be used to calculate the sum of the difference between the multiples of the variables expression as follows;

[tex]\sum\limits_{i = 1}^{124} (29\cdot a_i - 13 \cdot b_i)[/tex] = -30

The distributive property states that multiplying the difference between addend by a value produces a result which is equivalent to the multiplication of each addend individually and finding the difference from the resulting values.

The distributive property of multiplication indicates that we get;

Where; [tex]\sum\limits_{i=1}^{124} a_i = -10[/tex], and [tex]\sum\limits_{i=1}^{124} b_i = -20[/tex]

[tex]\sum\limits_{i=1}^{124} (29\cdot a_i - 13\cdot b_i) = 29 \times \sum\limits_{i=1}^{124} a_i - 13 \times \sum\limits_{i=1}^{124} b_i = 29 \times (-20) - 13 \times (-10))[/tex]

29 × (-10) - 13 × (-20) = -30

A linear equation is an equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c

Linear equation with two variables, when graphed on a cartesian plane with axes of those variables, give a straight line.

For the table to represent a linear function, the function must have a constant slope between any two points.

For the first table, the slope between the first two points is,

m = (7-3)/(2-1) = 4

The slope between the last two points is,

m = (15-11)/(4-3)

This has to do with the solution the quadratic equation given as: y=x² - 5x -14.

To factorize the quadratic equation - y =  x² - 5x -14, we need to find two numbers that multiply to -14 and add up to -5.

We can list out the factors of -14 as follows:

-1 and 14

1 and -14

-2 and 7

2 and -7

Out of these pairs, the numbers that add up to -5 are -2 and 7.

Therefore, we can factorize the equation as:

y = (x - 2)(x + 7)

To find the zeros or x-intercepts, we set each factor equal to 0 and solve for x:

x - 2 = 0, x + 7 = 0

x = 2, x = -7

So the solutions are (2, 0) and (-7, 0).

The axis of symetry is the average of the x-intercepts

This is (2 - 7)/2 = -2.5.

Substituting this  value into   the equation:

y = (-2.5 )² - 5 (-2.5 ) - 14 = -  20.25

So the vertex is (  -2.5, -20.25).

The domain of the function is all real numbers, since there are no restrictions on the input x.

The range of the function is y ≥ -20.25, since the vertex is the lowest point of the parabola and the graph extends upward from there. See the graph attached.

x < -2 is the solution for the given inequality.

To solve the inequality:

-3(x - 3) > 5 - 5x

We can start by using the distributive property and simplifying both sides of the inequality:

-3x + 9 > 5 - 5x

Next, we can add 5x to both sides of the inequality to get the x terms on one side:

2x + 9 > 5

Then, we can subtract 9 from both sides of the inequality to isolate the variable:

2x > -4

Finally, we divide both sides by 2, remembering to reverse the inequality because we are dividing by a negative number (-3):

x < -2

Therefore, the solution to the inequality is x < -2.

The addition of the outlier will affect the distribution in that b) The distribution will become skewed left.

When a score of 12 is added as an outlier, it shifts the distribution of data towards the left-sided direction resulting in skewness. This can be deduced from observing that the median is closer to the lower end of the range of collected data.

Additionally, the introduction of the outlier has substantially decreased the mean value, indicating that the deviation value has pulled the mean downwards and altered the symmetry of the original distribution by making it asymmetrically distributed in a leftward manner.

Let's use D to represent the driven pulley's diameter. The speed decrease needed, according to the issue description, is a 4 to 1 reduction.

This implies that the ratio of the diameters is also 4 to 1, as the speeds are inversely proportional to the diameters:

D/4 = 1/4

To find the probability of A and L, we need to find the number of elements in the intersection of A and L and divide by the total number of elements in the set S.

= {21, 23, 29, 30}

L = {x ∈ S | x < 25}

From the question, we have the following trigonometry function that can be used in our computation:

sin310°

The above expression is a sine function of 310 degrees

By mathematical expression, we have

360 - 50 = 310 degrees

This means that we can replace 310 degrees with (360 - 50) degrees in sin310°

So; in terms of 50 degrees, we have

sin310° = sin(360 - 50)°

Hence, the expression sin310° in terms of 50 degrees is sin(360 - 50)°
