Need the answer!!!!!

The money he will make in a five-month period is $7500.

According to the question,

We have the following information:

A gym employee earn the same amount each month. After working for three month, he earned $4,500.

Now, we will first find how much he has earned in one month by dividing the total salary with the number of months.

Note that the salary is directly proportional to the number of months with constant $1500.

So, we have the following expression:

3 months = 4500

1 month = 4500/3

1 month = $1500

Now, we can find the amount in five months period using multiplication.

5 months = 5*1500

5 months = $7500

Hence, the money he will make in a five-month period is $7500.

The probability that the student is a boy with glass is 3/20

Number of boys in the class = 6 boys

Number of girls in the class = 14 girls

Half of the boys wear glass

The number of boys that wear glass = 6 / 2

= 3 boys

Total number of students in the class = 6 + 14

= 20 students

Probability = Number of favorable outcomes / Total outcomes

= The number of students that wear glass / Total number of students

Substitute the values in the equation

= 3/20

The equation:

1/3y = -1

Is equivalent to a horizontal line, so the equation is linear.

A general linear equation is written as:

y = m*x + b

Where m is the slope of the line and b is the y-intercept

In this case, we have the equation:

1/(3y) = -1

So "y" is on the denominator, if we multiply both sides by y, we get:

1/3 = -y

Now we can multiply both sides by -1:

-1/3 = y

So we have a linear equation with a slope equal to zero:

y = 0*x - 1/3 = -1/3

This is a horizontal line.

Rounded to three decimal places, the standard deviation of the sampling distribution of the sample proportion is 0.024.

The degree of variance or dispersion of a collection of numbers from the mean is measured by standard deviation. It is calculated as the square root of variance, which is the average of the squared deviations from the mean. A low standard deviation suggests that the values are close to the mean, whereas a high standard deviation suggests that the values are dispersed over a wider range. In many other disciplines, including finance and economics, standard deviation is frequently used to assess the risk or volatility of a particular dataset. It is also frequently used in statistics and probability theory. Due to its ability to objectively compare and contrast various values, it is a crucial statistic for comprehending and analyzing data.

How to solve?

sqrt( (population proportion * (1 - population proportion)) / sample size)

Answer:

Length is 14 yd width is 11 yd

Step-by-step explanation:

The equation to find the perimeter is  ( 2 x Length ) + ( 2 x Width ), so first you divide the perimeter by 2 so we only have to add length + width, you get 25 yds. Since the length is 3 yds longer than width, you can mentally assume Length is going to be 14 yds and width is 11 yd, since Length is 3 yd longer, and finally if you add them together, 14 + 11 = 25. (Apologies if you don't understand I'm not good at explaining)

The coordinates  of the image of (5, 2) if it was reflected over the x-axis and then that image was reflected over the y-axis. is (-5, -2)

We need to find the coordinates of the image of (5, 2) if it was reflected over the x-axis and then that image was reflected over the y-axis.

When an object is reflected over the x axis, the y coordinate changes

(x, y) reflected in x axis gives (x, -y)

So, the point (5, 2) is reflected over x axis, it becomes (5, -2)

Now this image is gain reflected over y axis

When an object is reflected over the y axis, the y coordinate changes

(x, y) reflected in y axis gives (-x, y)

So, the point (5, -2) is reflected over y axis, it becomes (-5, -2)

Therefore, the coordinates  of the image of (5, 2) if it was reflected over the x-axis and then that image was reflected over the y-axis. is (-5, -2)

The ramp would be 5.4 inches high

The angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.

Angle of elevation of ramp = 16°

Height of ramp = h

The height of the ramp, length off fiber board and length of ramp form a right angle triangle with acute angle 16°

tan 16 = opposite/adjacent

tan 16 = h /19

By cross multiplying,

h = 19 tan 16

Step-by-step explanation:

Step 1: Define a Function

Recall that a graphed relation can only be a function if every input (x-value) has exactly one output (y-value), and not the other way around. That is, a function can have the points (2, 3) and (3, 3), but not (2, 3) and (2, 4), for example. This information will be very useful in solving this problem.

Step 2: Take Inventory of the Current Points

Let's first take into account what points we already have plotted. Using the graph, we can see that our current 4 points are (-3, 0), (-1, 1), (1, 2), and (3, 3). Again, the y-values do not really matter here as they can be repeated, but the x-values are what we need to pay attention to, so let's disregard the y-values of the points and just list the x-values as x = -3, -1, 1, and 3.

Step 3: Use this Information to Choose the Correct Answer

We know that in order to still be a function, the point we add must have an x-value that is not among the above list (and if it is, it must be the same exact point - e.g. if one of the options was (-3, 0), then it would technically work, but that is not the case with any of these points so we can ignore this possibility).

We can see that the x-values of the options are x = 1, 3, -3, and 0. Of these options, 1, 3, and -3 are already in our list, so those are not correct. Therefore, the only point that will keep the graphed relation a function is (0, 0). (Don't worry that the graph doesn't look like a straight line, a function is defined as any set of points that has exactly one output for every input - this does not necessarily mean the function follows an equation as we may normally think!)

The sum of the interior angles for a pentagon is 540°

Sum of Interior Angles of a Pentagon :

The interior angles of a pentagon sum up to 540 degrees.. Regardless of how regular or irregular the pentagon is, this is true. By dividing the whole amount by 5, we can calculate the size of each internal angle in the case of regular pentagons. To determine the measure of a missing angle in the situation of irregular pentagons, we must first know the measurements of other angles.

Any pentagon's internal angles add up to 540° in the same way. This holds true regardless of how regular or irregular the pentagon is. By using the polygon angle sum formula, the following sum is obtained:

(n-2)180(n−2)×180°

where n represents the polygon's number of sides. We have n = 5 in the case of a pentagon. Consequently, utilizing the formula:

=(n-2)180=(n−2) ×180°

= (5-2) 180= (5−2) ×180°

= (3) 180= (3) ×180°

= 540=540°

Consequently, a pentagon's interior angles add up to 540 degrees.

The vertex form of the parabola is y = a[tex](x-h)^2[/tex]+ k.

What is vertex form ?

            When a graph crosses its symmetry axis, the vertex formula in mathematics aids in determining the parabola's vertex coordinate. The typical representation of the vertex point is (h, k). We are aware that y=a[tex]x^2[/tex]+bx+c is the typical equation for a parabola. The vertex in this case, if the coefficient of [tex]x^2[/tex] is positive, should be at the base of the U-shaped curve. The vertex of a U-shaped curve should be at the top if the coefficient of [tex]x^2[/tex] is negative.

Here We know that the standard form of the parabola is y=a[tex]x^2[/tex]+bx+c.

Thus, the vertex form of a parabola is y = a[tex](x-h)^2[/tex]+ k.

The vertex formula is used to find the vertex of a parabola. There are two ways to find the vertex of a parabola.

Vertex, (h, k) = (-b/2a, -D/4a)

Where “D” is the discriminant where D = [tex]b^2[/tex] – 4ac.
