The probability that a randomly selected individual will score between 90 and 110 on this test is 0.6826. The score the employer will use to decide job offers is 123.3 to decide job offers for potential "high flyers."

The IQ test is designed to have a mean of 100 and a standard deviation of 10. This means that the test follows a normal distribution with a mean of 100 and a standard deviation of 10.

(a) The probability that a randomly selected individual from the population will score between 90 and 110 on this test can be found using the standard normal distribution table. We need to find the z-scores for 90 and 110 and then use the table to find the corresponding probabilities.

The z-score for 90 is (90 - 100) / 10 = -1
The z-score for 110 is (110 - 100) / 10 = 1

Using the standard normal distribution table, we find that the probability for a z-score of -1 is 0.1587 and the probability for a z-score of 1 is 0.8413.

The probability that a randomly selected individual will score between 90 and 110 is the difference between these two probabilities:

0.8413 - 0.1587 = 0.6826

So the probability that a randomly selected individual will score between 90 and 110 on this test is 0.6826.

(b) The employer wants to identify potential "high flyers" and intends to do this using the outcome of the IQ test. If the employer offers these positions to people with IQs in the top 1% of the population, we need to find the z-score that corresponds to the top 1% of the population.

Using the standard normal distribution table, we find that the z-score that corresponds to the top 1% of the population is 2.33.

Now we can use the z-score formula to find the corresponding IQ score:

z = (x - mean) / standard deviation

2.33 = (x - 100) / 10

Solving for x, we get:

x = (2.33 * 10) + 100 = 123.3

So the employer will use a score of 123.3 to decide job offers for potential "high flyers."

Answer:

Width=7

Length=21

Step-by-step explanation:

Width=x

length=3x

x+x+3x+3x=56

8x=56

x=7

width = x = 7

length = 3x = 21

Answer:

Length = 21 and Width = 7

Step-by-step explanation:

Length (L)= 3x width (W)

L = 3W

Perimeter (P) = 56

Perimeter = 2L + 2W

56 = 2(3W) + 2W

56 = 6W + 2W

56 = 8W

W = 56/8

W = 7

L = 3W

L = 3(7)

L = 21

therefore Length = 21 and Width = 7

Domain:

The domain is the set of x-values used by the graph.  Because the graph is connected, you can ask yourself the following:

"From how far left to how far right (with respect to the x-axis) does this graph go?"

In terms of x-values, the graph goes to -5 on the left and 2 on the right.  It gets to -5, but has open circles are 2.

-5≤x<2 would be the domain.

Range:

The range is the set of y-values used by the graph.  Because the graph is connected, you can ask yourself the following:

"From how far down to how far up (with respect to the y-axis) does this graph go?"

In terms of y-values, the graph goes to about -3 (or -3.2?) on the bottom and as high as 5.  Both of those values occur at open circles, so it never actually gets that low or that high.

-3<y<5 would be the range.

Both of those answers are assuming your scale is 1 on each axis.

Answer:

Step-by-step explanation:

One of the more obvious "connections" between linear equations is the presence of the same two variables (e. g., x and y) in these equations.

Assuming that your two equations are distinct (neither is merely a multiple of the other), we can use the "elimination by addition and subtraction" method to eliminate one variable, leaving us with an equation in one variable, solve this 1-variable (e. g., in x) equation, and then use the resulting value in the other equation to find the value of the other variable (e. g., y).  By doing this we find a unique solution (a, b) that satisfies both original equations.  Not only that, but also this solution (a, b) will also satisfy both of the original linear equations.

I urge you to think about what you mean by "analyze connections."  

The existence of the same 2 factors (x,y), in these solutions, is by far the most obvious connection between linear equations, and the further calculation can be defined as follows:

The independent set in a graph is a set of vertices that contain no edges. So, no neighboring vertices are included. The max independent set problem is to get an independent set of maximum size in graph G.

The solution for this question is discussed below:

a) The integer linear program for the max independent set problem is as follows:

maximize ∑x_i Subject to: x_i+x_j ≤ 1 {i,j} ∈ E;x_i ∈ {0, 1} ∀i. The variable x_i can represent whether the ith vertex is in the independent set. It can take on two values, either 0 or 1.

b) The LP relaxation for the max independent set problem is as follows:

Maximize ∑x_iSubject to:

xi+xj ≤ 1 ∀ {i, j} ∈ E;xi ≥ 0 ∀i. The variable xi can take on fractional values in the LP relaxation.

c) The family of graphs is as follows:

Consider a family of graphs G = (V, E) defined as follows. The vertex set V has n = 2^k vertices, where k is a positive integer. The set of edges E is defined as {uv:u, v ∈ {0, 1}^k and u≠v and u, v differ in precisely one coordinate}. It can be shown that the size of the max independent set is n/2. Using LP, the value can be determined. LP provides a value of approximately n/4. Therefore, the ratio LP-OPT/OPT is at least c/4. Therefore, the ratio is in for a constant c>0.

d) The size of a max-independent set is equivalent to the number of vertices minus the minimum vertex cover size.

e) The 2-approximation algorithm for vertex cover implies a 2-approximation algorithm for the max independent set.

In the given computation, the error is in solving the distance of XZ. The square of -2 is not -4 for but +4.

The correct computation will be:

Therefore, according to the correct calculations, the triangle is an isosceles triangle.

The value of Δh for the interval t = 1 to t = 1.1 by taking the difference between the two values of h:
Δh = -3.36
Therefore, the value of Δh for the interval t = 1 to t = 1.1 is -3.36.

Using the given variables, the value of Δh for the interval t = 1 to t = 1.1 is 0.96.
Given that the variables are s, t and h where:
s = 16t², and
s + h = 64
Then we can replace s in the second equation with the value given in the first equation:
16t² + h = 64
Subtract 16t² from both sides:
h = 64 - 16t²
To find Δh for the interval t = 1 to t = 1.1, we need to evaluate the value of h at both values of t and then find the difference.
At t = 1:
h = 64 - 16(1)²
h = 64 - 16
h = 48
At t = 1.1:
h = 64 - 16(1.1)²
h = 64 - 19.36
h = 44.64
Δh for the interval t = 1 to t = 1.1 can now be found by taking the difference between the two values of h:
Δh = 44.64 - 48
Δh = -3.36
Therefore, the value of Δh for the interval t = 1 to t = 1.1 is -3.36.

We know that:
s = 16t² ... (1)
s + h = 64 ... (2)
We need to find Δh for the interval t = 1 to t = 1.1.
Firstly, we can use equation (1) to find the value of s for t = 1 and t = 1.1:
At t = 1:
s = 16(1)²s = 16
At t = 1.1:
s = 16(1.1)²
s = 19.36
Next, we can use equation (2) to find the value of h for t = 1 and t = 1.1:
At t = 1:
s + h = 64
16 + h = 64
h = 64 - 16
h = 48
At t = 1.1:
s + h = 64
19.36 + h = 64
h = 64 - 19.36
h = 44.64
Finally, we can find the value of Δh for the interval t = 1 to t = 1.1 by taking the difference between the two values of h:
Δh = 44.64 - 48
Δh = -3.36
Therefore, the value of Δh for the interval t = 1 to t = 1.1 is -3.36.

The equation of the line in slope-intercept form is y = 6x + 55.

Equations can involve variables, which are placeholders for unknown values that we wish to find. For example, the equation x + 3 = 7 asserts that the value of x plus 3 is equal to 7. We can solve for x by subtracting 3 from both sides of the equation, obtaining x = 4.

Equations can be linear or nonlinear, and they can involve one or more variables. They can be represented in various forms, such as standard form, slope-intercept form, or quadratic form.

To find the equation of the line in point-slope form, we need to first find the slope of the line. We can use any two points from the table to find the slope using the formula:

slope = (change in y)/(change in x)

Let's use the first and last points in the table:

slope = (295 - 175)/(40 - 20) = 120/20 = 6

Now we can use the point-slope form of the equation of a line:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is any point on the line. Let's use the first point (20, 175):

y - 175 = 6(x - 20)

To write this equation in slope-intercept form, we need to isolate y:

y - 175 = 6x - 120

y = 6x + 55

So the equation of the line in slope-intercept form is y = 6x + 55.

Step-by-step explanation:

There are 280.035 lbs in 127 kilograms. The answer is obtained by applying the unit conversion.

What is unit conversion?

A unit conversion is used to express the same property in a different unit of measurement. For instance, you could use minutes instead of hours to represent time or feet instead of miles to indicate distance. It commonly occurs when measurements are provided in one system of units, such as feet, but are required in a different system, such as chains.

Now,

we have been given 127 kilograms which are to be converted into pounds and to be represented in lbs.

We know that 1 kilogram = 2.205 lbs (approx)

Therefore,

⇒127 kilograms = 127 * 2.205

⇒127 kilograms = 280.035 lbs

The solution to the equation 9(b - 2) = -7 + 0 is b = 11/9.

Given the equation in the question:

9( b - 2 ) = -7 + 0

To solve the equation, first apply distributive property to remove the poarenthesis:

9( b - 2 ) = -7 + 0

9×b + 9×-2 = -7 + 0

9b - 18 = -7 + 0

Next, we simplify the right side of the equation:

9b - 18 = -7

To isolate the variable 'b,' we need to get rid of the constant term (-18) on the left side. We can do this by adding 18 to both sides of the equation:

9b - 18 + 18 = -7 + 18

Simplifying further:

9b = -7 + 18

Add -7 and 18

9b = 11

Now, we want to solve for 'b,' so we divide both sides of the equation by 9:

9b/9 = 11/9

b = 11/9
