Answer:

(2,-1)

Step-by-step explanation:

The ys in both questions are isolated on one side of the equation in both. The numerical coefficient of both is 1. Therefore you should equate the the left side of each equation to the other left side. The solution is the easiest one to solve because there is only 1 unknown on both sides.

4x - 9 = x - 3                      Subtract x from both sides.

4x-x - 9 = -3                       Combine

3x -9 = - 3                          Add 9 to both sides

3x - 9+9 = - 3+9

3x = 6                                Divide by 3

3x/3 = 6/3

x = 2

===============

Now use the second equation to solve for y

y = x - 3

y = 2 - 3

y = -1

==============

The solution is (2,-1)

The results of an independent-samples t test were t(19) = 4.02, p < 0.05. The sample size is 19.

The independent t-test is a defined as an statistical test in order to determine if we have statistically significant difference between the means of two unrelated groups.

Effect size is defined as a "quantitative measure of the magnitude of the experimenter effect" So, If we have a high value for the effect size then we can conclude that we have a stronger relationship between two variables.

T test is used to compare group means is one of the most common tests and is used to determine whether the means of two groups are equal to each other.

We perform one sample z-test;

One sample z-test is performed if the sample size is large enough (n  > 30) and we want to know if the sample comes from the specific population.

The results of an independent-samples t test were t(19) = 4.02, p < 0.05. In this example,

The sample size is 19.

Step-by-step explanation:

180-104 is 76 76-10=66 66/2 is 33

Answer: x = 33

Step-by-step explanation:

Well since that line is basically equal to 180 all you have to do is plug in those numbers for x. Since 33 + 10 = 43 Alll you gotta do is add that up. So we have 104 + 33 + 43 = 180. I’m not the best at explaining things but I hope this helped :)

Answer:

n = 10

Step-by-step explanation:

n is the altitude of the right triangle.

Apply the right triangle altitude theorem/geometric mean theorem to find n.

Which is:

h = √(xy)

Where,

h = n =?

x = 5

y = 20

Plug in the value into the equation

n = √(20*5)

n = √100

n = 10

Answer:

Total Sharon spent $660 for the tv

The down payment was $210

The amount that she paid for rent after 6 months is $450

Step-by-step explanation:

To find out how much her down payment was you would need to find out how much 10% of $2,100 is which is $210, so you know her down payment was $210.

Then you would find out the total cost of rent is after 6 months so you would do 6 times $75 which is $450. So if she decides to not buy it then after 6 months she would have spent $450 to rent it.

And total she would have spent $660 which you can find out by doing $450 + $210 = $660.

Answer:

To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.

The set of five numbers would be {2,4,4,4,6}

Answer:

The example set could be:

S

=

{

2

,

4

,

4

,

4

,

6

}

See explanation.

Explanation:

First you can notice that if the set was:

S

1

=

{

4

,

4

,

4

,

4

,

4

}

then it would fulfill 2 conditions: mean and median, but

the set does not have the mode because all numbers are the same,

the range is zero (again all numbers are the same)

To have the mode the set would have to have at least one element different from

4

, but if we changed only one element the mean would change, so at least two numbers need to be changed to keep mean equal to

4

..

Now to get the range the difference between the changed numbers should be

4

. That leads us to adding two to one number and subtracting two from the other.

Finally we can get the set from the answer.

[tex]x^{2}[/tex] + (y-5)² = 8

After answering the question provided, we can predict that the result will be as in the triangle by Pythagorean theorem = [tex]\sqrt{12^2 - 4^2}[/tex] => N = [tex]\sqrt{144 - 16}[/tex] => n = [tex]\sqrt{132}[/tex]

A triangle is a polygon because it includes four or so additional parts. It features a simple rectangular shape. A rectangle having edges A, B, and C is referred to as a triangle. When the sides are actually not collinear, Euclidean geometry yields a single plane and cube. If a triangle contains three parts and three angles, it is a polygon. The intersections of a triangle's three sides are referred to as its corners. The sum of a triangle's sides is 180 degrees.

by Pythagorean theorem

n = [tex]\sqrt{12^2 - 4^2}[/tex]

N = [tex]\sqrt{144 - 16}[/tex]

n = [tex]\sqrt{132}[/tex]

have a great day!!

The cube root function , has no domain restrictions. The domain of the cube root function is all real numbers, or ℝ .

The domain of a function is the complete set of possible values of the independent variable.

The domain is the set of all possible x-values which will make the function "work", and will output real y-values.

When finding the domain, remember:

The denominator (bottom) of a fraction cannot be zero.

The number under a square root sign must be positive in this section.

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Domain: (- ∞ , ∞) , {x | x ∈ [tex]\mathbb{R}[/tex]}

Hence, The domain of the cube root function is all real numbers, or ℝ .

Find the Reference Angle (17pi)/10

17π1017π10

Since the angle 17π/ 10 is in the fourth quadrant, subtract 17π/10 from2π.

2π−17π/10

The angle between 0 to [tex]2\pi[/tex] that is coterminal with [tex]-\frac{17\pi }{10}[/tex] is [tex]\frac{3\pi }{10}[/tex].

Coterminal angles are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side.

Angles are considered to be in standard position if the initial side is on the positive x-axis and the vertex at the (0,0) point of the Cartesian plane. All angles generated that share the same terminal side are coterminal angles. These are angles that have differences of multiples of 360n or n2pi where n is an integer.

A coterminal angle is found by simply adding or subtracting 360 and its multiples.

The coterminal angles of 20 degrees for example are 20 + 360 = 380 or 20 - 360 = -340. This may continue by adding or subtracting 360 each time.

To get coterminal angles, you simply have to add or subtract 2[tex]\pi[/tex].

According to this problem,

We are looking for a coterminal angle that is between 0 to 2[tex]\pi[/tex], so we will add [tex]2\pi \ to \ \frac{-17\pi }{10}[/tex].

= [tex]\frac{-17\pi }{10} +\frac{20\pi }{10}[/tex]

= [tex]\frac{-17\pi +20\pi }{10}[/tex]

= [tex]\frac{3\pi }{10}[/tex]

Hence,

The angle between 0 to [tex]2\pi[/tex] that is coterminal with [tex]-\frac{17\pi }{10}[/tex] is [tex]\frac{3\pi }{10}[/tex].
