A company has recently been hiring new employees. Today the company has 36% more employees than it did a year ago. If there are currently 44200 employees, how many employees did the company have a year ago?

The z-value obtained from the test was 2.25, and the p-value was less than 0.02.

What is probability ?

Probability can be defined as ratio of number of favourable outcomes and total number of outcomes.

Based on the experiment described, a two-sample z-test for the difference in proportions was conducted to determine if there is a significant difference between the proportion of rats that succeeded in the maze after being given substance m and the proportion of rats in the control group that succeeded in the maze.

This suggests that the difference in proportions between the two groups is statistically significant at the 0.05 level of significance (since the p-value is less than 0.05).

In other words, the results of the experiment suggest that substance m may be effective in helping to restore memory, as a greater proportion of rats in the substance m group succeeded in the maze compared to the control group. However, it's important to note that further experiments and analyses would be necessary to confirm these findings and determine the extent of the effect of substance m on memory restoration.

Therefore, The z-value obtained from the test was 2.25, and the p-value was less than 0.02.

Therefore , the solution of the given problem of percentage comes out to be  the original price of the hammer is $23, and the customer saved $5.75 with the discount code.

In mathematics, a percentage is any value that can be represented as a fraction of 100. There are also sporadic uses of the abbreviations "pct.," "pct," or "pc." Nonetheless, it is typically denoted by the "%" symbol. The proportional amount is flat and lacks any dimensions. As percentages have a numerator of 100, they can be thought of as fractions. The percent symbol (%) must come after a number to denote that it is a percentage. .

Here,

Let x be the original price of the hammer.

With the 25% discount, the customer pays 75% of the original price:

0.75x

And since there is free shipping, the customer pays only the price of the hammer:

0.75x = 17.25

Solving for x, we have:

x = 17.25 / 0.75 = 23

Therefore, the original price of the hammer is $23, and the customer saved $5.75 with the discount code.

As a result, option B is the equation that finds the equation of the line: y/x = 2/3.

An equation is a mathematical statement that indicates that two expressions are equal. It is a statement of equality that contains one or more variables, which are usually represented by letters. An equation consists of two sides separated by an equal sign (=). The left-hand side (LHS) and the right-hand side (RHS) of the equation may contain different expressions, which may include numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division.

Here,

To find the equation of the line that passes through the points (0,0) and (6,4), we can use the slope-intercept form of the equation of a line, which is y = mx + b, where m is the slope of the line and b is the y-intercept.

The slope of a line is given by the rise over run, or the change in y divided by the change in x, between any two points on the line.

We can use the coordinates (0,0) and (6,4) to find the slope of the line:

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

= (4 - 0) / (6 - 0)

= 4/6

= 2/3

Therefore, the slope of the line is 2/3.

To find the equation of the line, we can use the point-slope form of the equation of a line, which is:

y - y1 = m(x - x1)

where (x1, y1) is any point on the line. We can use the point (0,0), so the equation becomes:

y - 0 = (2/3)(x - 0)

Simplifying, we get:

y = (2/3)x

Answer:

if Hassan got 48/50 and scored an overall 5.7/6.0, and Emily got 32/40, her overall score would be approximately 5.6/6.0 (rounded to one decimal place).

Step-by-step explanation:

If Hassan got 48/50 and scored an overall 5.7/6.0, what would Emily's overall score be is she got 32/40?​

To determine Emily's overall score, we can use a proportion:

Hassan's score / Hassan's total = Emily's score / Emily's total

Substituting the given values, we get:

48/50 = 32/Emily's total

To solve for Emily's total, we can cross-multiply:

48/50 * Emily's total = 32

Simplifying the left-hand side, we get:

0.96 * Emily's total = 32

Dividing both sides by 0.96, we get:

Emily's total = 33.33 (rounded to two decimal places)

Now, we can use another proportion to find Emily's overall score:

Emily's score / Emily's total = 5.7/6.0

Substituting the value of Emily's total that we just found, we get:

Emily's score / 33.33 = 5.7/6.0

Solving for Emily's score, we get:

Emily's score = 31.4 (rounded to one decimal place)

Therefore, if Hassan got 48/50 and scored an overall 5.7/6.0, and Emily got 32/40, her overall score would be approximately 5.6/6.0 (rounded to one decimal place).

In mathematics, an equation is a statement that asserts the equality of two expressions. An equation contains one or more variables, which are unknown values that can vary or change. The variables are usually represented by letters such as x, y, or z. The expressions on either side of the equals sign can be constants, variables, or functions of variables.

The simplest form of an equation is a linear equation, which can be represented as ax + b = c, where a, b, and c are constants and x is a variable. To solve a linear equation, we need to find the value of the variable that makes the equation true. This is done by performing arithmetic operations on both sides of the equals sign to isolate the variable.

Equations can also be more complex, involving multiple variables, powers, and functions. In such cases, algebraic techniques such as factoring, substitution, and solving systems of equations may be required to find the solution.

Equations are used to describe relationships between variables in many fields of study, including physics, chemistry, economics, and engineering. They are also used in everyday life, such as in calculating the cost of a purchase after applying a discount, or determining the amount of time it takes to travel a certain distance

To find the percentage of games won, we need to divide the number of games won by the total number of games played and multiply by 100%:

percentage of games won = (number of games won / total games played) x 100%

total games played = number of games won + number of games lost = 21 + 3 = 24

percentage of games won = (21 / 24) x 100%

Answer:

12 feet

Step-by-step explanation:

Let x be the length of the shorter part of the pipe.

According to the problem, the longer part is three times as long as the shorter part. Therefore, the length of the longer part is 3x.

We also know that the sum of the lengths of the two parts is equal to the original length of the pipe, which is 16 feet.

So we can write an equation:

x + 3x = 16

Simplifying this equation, we get:

4x = 16

Dividing both sides by 4, we get:

x = 4

So the length of the shorter part is 4 feet, and the length of the longer part is 3 times as long, or 3 × 4 = 12 feet.

Answer:

Step-by-step explanation:

A. To plot the circles x^2+y^2=4 and x^2+y^2=1 on the same coordinate plane, we can use the standard form of the equation of a circle:

For x^2+y^2=4, the radius is 2 and the center is at the origin (0,0).

For x^2+y^2=1, the radius is 1 and the center is also at the origin (0,0)

B. To find the image of any point on x^2+y^2=4 under the transformation (x,y) to (1/2x,1/2y), we can substitute the values of x and y from the original equation into the transformation rule. Let's take the point (2,0) as an example:

(1/2x,1/2y) = (1/22, 1/20) = (1,0)

Therefore, the point (2,0) will go to the ordered pair (1,0).

C. We can notice that x^2+y^2=1 is a smaller circle that is completely contained within x^2+y^2=4, which is a larger circle. The smaller circle is a dilation of the larger one using the origin as a center and a scale factor of 1/2. This means that every point on the smaller circle is half the distance from the origin as the corresponding point on the larger circle. In other words, the smaller circle is a scaled-down version of the larger one.

The shareholder's equity if $450 was put on credit is $175. Option D

The purchase of equipment for $625 represents a decrease in the company's shareholder equity, since assets have increased while the equity has not changed.

If $450 was put on credit, this means that the company has only paid $625 - $450 = $175 towards the equipment.

The shareholder's equity is reduced by this amount, so the new shareholder's equity is:

Shareholder's equity = Initial equity - Decrease in equity

Shareholder's equity = 0 - $175

Shareholder's equity = -$175

Since the shareholder's equity is negative, it means that the company owes more than it owns. Therefore, the answer $175.

How to find Reflection of a point?

When a point is reflected across the X-axis, the x-coordinates remain the same. But the Y-coordinates are transformed into their opposite signs. Therefore, the reflection of the point (x, y) across X-axis is (x, -y).

The reflected point will be equidistant from the point over which it is reflected as the original point and in the same line as the original point and the reflected point.

Find the difference between the x and y values of the given points and add that value (distance) to the reflection point.

Step-by-step explanation:

I factored the square root of 8 into the square root of 2 times the square root of 2, because I believe that the square root of 8 was supposed to be factored based upon the hint provided.

This resulted in the expression 3√2 * 3√2, which is equivalent to 3*3*sqrt(2) * sqrt(2).

The limit of each function at the given point i n the question 10 to 14, is explained below.

A function may get close to two distinct limits. There are two scenarios: one in which the variable approaches its limit by values larger than the limit, and the other by values smaller than the limit. Although the right- and left-hand limits are present in this scenario, the limit is not defined.

When a variable approaches its limit from the right, the function's right-hand limit is the value that approaches.a

10). The limit of f(z) = Arg z as z approaches Zo = 1 does not exist. This is because the argument function is not continuous at the point z = 1, where there is a branch cut.

11). The limit of f(z) = [tex](1 - lm z)^{-1}[/tex] as z approaches z0 = -8 does not exist. This is because the function approaches infinity as z approaches -8 from the left, and negative infinity as z approaches -8 from the right.

However, if we consider the limit of f(z) as z approaches z0 = -8 + i from both the left and the right, the limit exists and is equal to 0. This is because in the complex plane, the value of Im z cannot exceed 1, so as z approaches -8 + i, the denominator (1 - Im z) approaches 0, and the function approaches infinity. However, the numerator approaches a finite value of 1, which cancels out the denominator, and the overall limit is equal to 0.

12). The limit of f(z) = (z - 2) log(z - 2) as z approaches z0 = 2 is 0. This is because the term (z - 2) approaches 0 as z approaches 2, and log(z - 2) approaches 0 as well because log(z - 2) is continuous at z = 2. Therefore, the limit is equal to 0.

13). The limit of f(z) = -1/z as z approaches z0 = 0 does not exist. This is because as z approaches 0, the magnitude of 1/z approaches infinity, but the direction of approach depends on which quadrant the limit is approached from. Since the limit does not approach a unique value from all directions, the limit does not exist.

14). The limit of f(z) = 2 + [tex]2^{1/z}[/tex] as z approaches infinity does not exist. This is because as z approaches infinity, the term  [tex]2^{1/z}[/tex] approaches 1, and the limit approaches 2 + 1 = 3. However, if we approach infinity along the real axis, the limit of [tex]2^{1/z}[/tex] approaches 1, but if we approach infinity along the imaginary axis, the limit of [tex]2^{1/z}[/tex] approaches infinity. Therefore, the limit of f(z) does not exist.
