The salary corresponding to z=1 is $64587 if the average teacher's salary in a particular state is $54,137.

A Z-score is a metric that quantifies the connection between a value and the mean of a set of values. The Z-score is measured as the standard deviations from the mean. If the Z-score is 0, A data point's score is the same as the mean score. In statistics, a raw score's value that deviates or surpasses the mean of the phenomenon being observed or measured is referred to as the standard score. Raw scores above the mean are given positive standard scores, whilst raw values below the mean are given negative standard ratings.

The pay is 1 standard deviation above the mean, according to a z score of 1.

Therefore, the salary for a z-score of 1 is:

$54,137 + 1($10,450) = $64587

Therefore, the salary corresponding to z=1 is $64587

The linear equation written in the slope-intercept form is:

y = (-3/5)*x

The correct option is C.

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

Here we can see that the line crosses through the poin (0, 0), so the y-intercept is 0.

b = 0

y = a*x + 0

y = a*x

To find the value of a, we can use another point on the graph.

We can see that the linear equation passes through (5, - 3), replacing these values:

-3 = a*5

-3/5 = a

Then the linear equation is just:

y = (-3/5)*x

The golden ratio can be found using the following formula if we take x as the width, and y as the length of the rectangle:

[tex]\frac{y}{x} =\frac{x+y}{y} =1.618[/tex]

What is the golden ratio?

The golden ratio is a unique proportion between two values where the ratio of the two values equals the ratio of their sum to the bigger of the two values.

If we take a square of sides A,B,C,D.

Locate the midpoint of any one side of the square by bisecting it.

Connecting the midpoint (say) P to a corner of the opposite side.

Placing the compass on point P, and the width set to match the distance of P to one of the opposite sides, we draw an arc.

By extending the line where P sits, we see that the arc intersects at a point. say Q.

Extending the opposite line to P, we see that the point Q drawing parallel to the side, we see that it intersects at another point R.

Now, the rectangle AQRD is a golden ratio rectangle.

a. The inverse variation relationship between a and b can be expressed as a = k/b^2, where k is a constant. We are given that a is 1 when b is 3, so we can substitute these values into the equation to find k: 1 = k/(3^2). Solving for k, we get k = 9.

Substituting this value of k back into the equation a = k/b^2, we can find a when b is 5: a = 9/(5^2) = 9/25 = 0.36. Therefore, a is 0.36 when b is 5.

b. To find the distance it takes for a car traveling at 65 miles per hour to stop, we can use the equation for direct variation: d = kv^2, where d is the distance, v is the speed, and k is a constant. We are given that it takes 112 feet for a car traveling at 40 miles per hour to stop, so we can substitute these values into the equation to find k: 112 = k(40^2). Solving for k, we get k = 0.0056.

Substituting this value of k back into the equation d = kv^2, we can find the distance it takes for a car traveling at 65 miles per hour to stop: d = 0.0056(65^2) = 2256 feet. Therefore, it takes 2256 feet for a car traveling at 65 miles per hour to stop.

(where x is the original length of the pipe).

Original length of the pipe = 16 feet

Step-by-step explanation:

Let x be the original length of the pipe.

Given a plumber cuts 2 3/4 feet from a pipe and now has a pipe that is 13 1/4 feet long, the equation that models this is:

[tex]\boxed{ x-2 \frac{3}{4}=13 \frac{1}{4}}[/tex]

To determine the length of the original pipe, solve the equation for x.

Add 2 3/4 to both sides of the equation:

[tex]\implies x-2 \frac{3}{4}+2 \frac{3}{4}=13 \frac{1}{4}}+2 \frac{3}{4}[/tex]

[tex]\implies x=13 \frac{1}{4}}+2 \frac{3}{4}[/tex]

When adding mixed numbers, partition the mixed numbers into fractions and whole numbers, and add them separately:

[tex]\implies x=13 +\dfrac{1}{4}}+2 +\dfrac{3}{4}[/tex]

[tex]\implies x=13 +2 +\dfrac{1}{4}}+\dfrac{3}{4}[/tex]

[tex]\implies x=15 +\dfrac{1+3}{4}[/tex]

Answer:

18 miles

Step-by-step explanation:

To determine how many miles Brent can travel, we need to first determine the cost of the base fare and then subtract that from the total amount of money Brent has. The base fare is $1.23, so we can subtract that from the total amount of money Brent has to find out how much money he has left for the per-mile charge:

14.91 - 1.23 = 13.68

Now that we know how much money Brent has left for the per-mile charge, we can divide that amount by the per-mile charge to find out how many miles Brent can travel:

13.68 / 0.76 = 18 miles

Therefore, Brent can travel a maximum of 18 miles given the amount of money he has available to spend on the ride.

Isotopes(200g) are atoms that have the same number of protons in their nucleus, but a different number of neutrons. This means that they have the same atomic number, but a different atomic mass. Because of this, isotopes have different physical and chemical properties.
