The credit hours that a student has to take for the two tuition costs to be equal is A. 250 + 200h = 300 + 180h

From the information, the tuition costs, C, for a local community college are modeled by C(h) = 250 + 200h

h = the number of credit hours taken.

The local state university has tuition costs, S, modeled by the function S(h) = 300 + 180h.

Therefore, the credit hours that a student have to take for the two tuition costs to be equal will be:

250 + 200h = 300 + 180h

200h - 180h = 300 - 250

20h = 250

h = 250/20

h = 12.5 hours.

If the dining hall is located at (-12,6) and the stables are located at (20,6), then the dining hall is 32  units apart from the stables

The location of the dining hall = (-12,6)

The location of the stables = (20,6)

The distance between the two points d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Where d is the distance between the two points

[tex](x_1,y_1)[/tex] is the coordinates of the first point

[tex](x_2,y_2)[/tex] is the coordinates  of the second point

Substitute the values in the equation

d = [tex]\sqrt{20-(12))^2+(6-6)^2}[/tex]

To find the percent of happy people, we just have to divide the number of happy participants by the total number of them.

Then, we multiply it by 10 to express it as a percentage.

By solving the system of equations, we can see that the solutions are:

(A, B) = (4, 9)

(C, D) = (1, -6).

Here we have the following system of equations:

x^2 - y = 7

y - 5x = -11

If we isolate the variable y in both equations, we get:

y = x^2 - 7

y = -11 + 5x

Now we can equate these two to get:

x^2 - 7 = -11 + 5x

now we have a quadratic equation, this can be rewritten as:

x^2 - 7 + 11 - 5x = 0

x^2 - 5x + 4 = 0

Using the quadratic formula, we will see that the solutions are:

[tex]x = \frac{5 \pm \sqrt{(-5)^2 - 4*1*(4)} }{2*1}[/tex]

Solving that we get:

[tex]x = \frac{5 \pm \sqrt{(9} }{2} \\\\x = \frac{5 \pm 3}{2}[/tex]

So the two solutions for x are:

x = (5 + 3)/2 = 4

x = (5 - 3)/2 = 1

Evaluating the second equation in these x-values we get:

y = -11 + 5*4 = -11 + 20 = 9

y = -11 + 5*1 = -6

Then we have the coordinate pairs: (4, 9) (on the first quadrant) and (1, -6) on the fourth quadrant.

In the year 2006, the number of free throws is 100, number of 2 point field goals 128 and the number of 3 point field goals 90.

Let x = number of free throws

y = number of 2 point field goals

z =  number of 3 point field goals

However given that Rebecca has a total of 806 points,

Thus x + 2y + 3z = 806 ---------- equation 1

Number of 2 point field goals that Rebecca made was 52 less than double the number of​ three-point field goals she made ;

thus y = 2z - 52 ---------------- equation 2

Number of 3 point field goals that Rebecca made was 28 less than the number of​ two-point field goals she made ;

thus x = y - 28 ------------------ equation 3

Thus on solving these three above mentioned equations :

we get x = 2z - 52 -28 [ substituting values in eq 3 from eq 2]

x = 2z - 80 ------------- equation 5

So equation 1 becomes ; 2z - 80 + 2y + 3z = 806

5z + 2y = 886 -------------- equation 4

Thus on solving equation 4 and 2 we get

2 X equation 2 = 4z - 2y = 104

                            5z + 2y = 886

                      = 11 z = 990

thus z = 90 and so y = 4 × 90 - 104 = 2y

y= 360 - 104 / 2

= 256/2 = 128

thus y = 128 .

And x= 2z -80 from equation 5 ; x = 180 - 80 = 100 .

The two rectangles that is R3 and R4 have the greatest difference in the area.

How to calculate the area of the rectangle?

In mathematics, the rectangle is a closed polygon shape which has four vertex as well as four sides. And the opposite side are parallel to each other. To calculate the area, multiply the length and breadth. Similarly, for the perimeter means add all the sides.

According to the question, the given data in the form of the area of the rectangle is as follows:

Area of Rectangle1 = 60.81 square centimeters

Area of Rectangle2 = 61.44 square centimeters

Area of Rectangle3 = 35.52 square centimeters

Area of Rectangle4 = 47.88 square centimeters

Now, to calculate the greatest difference in the area of the rectangles:

Difference(Rect2 - Rect1) = 61.44 - 60.81 = 0.63

Difference(Rect1 - Rect3) = 60.81 - 35.52 = 25.29

Difference(Rect1 - Rect4) = 60.81 - 47.88 = 12.93

Therefore, the two rectangles that is R3 and R4 have the greatest difference in the area.

And the differences are as follows:

Area(Rect1 - Rect3) = 60.81 - 35.52 = 25.29 square centimeters

Area(Rect1 - Rect4) = 60.81 - 47.88 = 12.93square centimeters

Answer:

Step-by-step explanation:

$134 is the amount paid by grandparents every month.

Percentage as the name suggests is a ratio of some particles to 100. In order to get the value of the required amount one has to divide the value by 100.

It is given that the  tuition fee is $180 per week = $720 per month

It is also provided that she receives an honour rule of $50 per month.

So, her fees per month is $720- $50= $670.

It is given that 20% of the fees is paid by grandparents.

So, percentage share = 20% of $670 =20/100 x $ 670 = $134

Aryon is left with $9.25 of money after he has paid for his lunch.

According to the question,

We have the following details:

Total amount Aryon has = $20

The cost of 1 coke = $1.50

So, the cost of 2 cokes = $(2*1.50)

The cost of 2 cokes = $3

The cost of a sandwich = $5.50

The cost of a bag of chips = $2.25

So, the total cost of all the materials = the cost of 2 cokes + the cost of a sandwich + the cost of a bag of chips

The total cost of all materials = $(3+5.50+2.25)

The total cost of all materials = $10.75

Now, the money Aryon has = Total money he has - the total cost of all materials

The money Aryon is left with = $(20-10.75)

The money Aryon is left with = $9.25

Hence, the money Aryon is left with is $9.25.

Using the z-distribution, as we are working with a proportion, it is found that since the test statistic is less than the critical value for the right-tailed test, there is not enough evidence to conclude that there has been an increase in the proportion of all kochia plants that are resistant to glyphosate.

In null hypothesis, we test if there has been no increase, that is, the subtraction is of 0.

In this problem, we consider that:

p₁ is the proportion in 2014.

p₂  is the proportion is 2017.

H₀=p₂-p₁

By alternative hypothesis,

H₁=p₂-p₁≠0,

we test if there has been an increase

The proportions and standard errors are given by:

p₁=0.97, s₁=√0.97(0.803)/61=0.0509

p₂=0.385, s₁=√0.385(0.615)/52=0.0675

Hence, the distribution has mean and standard error given by:

p=p₂-p₁=0.0675-0.0509

s=√s₁²+s₂²=0.0845

Test static z=p bar-p/s

at p = 0 is the value tested at the null hypothesis,

z=0.0166/0.0845

z=0.2

By a right-tailed test,  we are testing is  the proportion is greater than a value, with a significance level of 0.05, the critical value is of

z=1.645

0.2<1.645 there is not enough evidence to conclude that there has been an increase in the proportion of all kochia plants that are resistant to glyphosate.

The value of the expression |-10+6|-|3²-5| = 0

The expression given is |-10+6|-|3²-5|.

This contains absolute value which needs to be evaluated.

We will go through the definition of absolute value.

Absolute value for x = x, when x is a positive integer.

i.e., |x| = x, when x >0

Absolute value of (-x) = x, when -x is a negative integer.

So absolute value always gives the positive value of the number inside it.

Now |-10+6|-|3²-5| = |-4| - |9-5|

                              = 4 - |4|    [Since |-4| = 4]

                              = 4 - 4      [Since |4| = 4]
