The length of TU is 8, WU is 10, TX is √39 and TV is 2√39. The solution is obtained using the properties of rhombus.

What is a rhombus?

A parallelogram has a unique variation known as a rhombus. A rhombus has opposing sides that are parallel and opposing angles that are equal.

The given figure TUVW is a rhombus.

We know that the diagonals of a rhombus always bisect each other perpendicularly which means at an angle of 90°.

Since, the diagonals bisect each other, therefore

WX=XU

We are given WX = 5 so, XU = 5

Thus, WU = WX + XU

WU = 5 + 5

WU = 10

In a rhombus, all the sides are equal, therefore,

UV = VX = WT = TU = 8

Since, the diagonals bisect each other perpendicularly, therefore, we have four right angled triangles.

Using pythagoras theorem in triangle UXV, we get

⇒UX^2 + XV^2 = UV^2

⇒5^2 + XV^2 = 8^2

⇒XV^2 = 8^2 - 5^2

⇒XV^2 = 64 - 25

⇒XV^2 = 39

⇒XV = √39

So, TX = √39

TV = TX + XV = √39 + √39 = 2√39

Hence, the length of TU is 8, WU is 10, TX is √39 and TV is 2√39.

The areas of the composite figures are 36 square units, 27 square units, 66 square units, 32+2π square units and 68 square units  respectively.

What are composite figures?

A composite figure is a shape that is produced from two or more fundamental shapes. Composite figures are also referred to as compound and complex shapes frequently.

Figure 1

This figure can be broken into two rectangles.

First rectangle with length 5 and width 4.

Second rectangle with length 8 and width 2 (as 6-4 is 2).

Area of rectangle= length*width

So, area of first rectangle= 5*4= 20 square units

Area of second rectangle= 8*2= 16 square units

Thus,

Area of figure= 20+16= 36 square units

Figure 2

This figure can be broken into two rectangles.

First rectangle with length 7 and width 3(as 6-3 is 3).

Second rectangle with length 2 and width 3.

Area of rectangle= length*width

So, area of first rectangle= 7*3= 21 square units

Area of second rectangle= 2*3= 6 square units

Thus,

Area of figure= 21+6= 27 square units

Figure 3

This figure can be broken into two rectangles.

First rectangle with length 12 and width 5.

Second rectangle with length 3 and width 2(as 12-(6+4) is 2).

Area of rectangle= length*width

So, area of first rectangle= 12*5= 60 square units

Area of second rectangle= 3*2= 6 square units

Thus,

Area of figure= 60+6= 66 square units

Figure 4

This figure can be broken into a rectangle and a semicircle.

Rectangle with length 8 and width 4.

Semi-circle with radius 2 ( as diameter is 4).

Area of rectangle= length*width

So, area of rectangle= 8*4= 32 square units

Area of semi-circle= 1/2πr^2

So, area of semi-circle= 1/2π(2)^2= 2π square units

Thus,

Area of figure= 32+2π square units

Figure 5

This figure can be broken into a rectangle and two squares.

Rectangle with length 10 and width 6(as 8-2 is 6).

Both squares with side 2.

Area of rectangle= length*width

So, area of rectangle= 10*6= 60 square units

Area of square= side^2

So, area of first square= 2^2= 4 square units

area of second square= 2^2= 4 square units

Thus,

Area of figure= 60+4+4= 68 square units

Hence, the areas of the composite figures are 36 square units, 27 square units, 66 square units, 32+2π square units and 68 square units  respectively.

The equation of the regression line is y = -0.43x + 63.27

To determine the equation of the regression line, we make use of a graphing calculator with the following summary:

The regression equation is represented as

ŷ = bX + a

So, we have

b = SP/SSX = -347.33/807.33 = -0.43022

a = MY - bMX = 35.17 - (-0.43*65.33) = 63.27457

This gives

ŷ = -0.43022X + 63.27457

Approximate

y = -0.43x + 63.27

Answer:

X = 16

Step-by-step explanation:

Hi again.

To solve this equation, use the logarithm property of equality to rewrite log7 (3x + 1) = 2 as 3x + 1 = 7^2.

We can then solve for x by subtracting 1 from both sides, giving us 3x = 7^2 - 1, then dividing both sides by 3 to get x = (7^2 - 1)/3.

Therefore, the solution is x = (7^2 - 1)/3.

So now, x will be 16.

a) A score that is 6 points above the mean corresponds to a z-score of (6 / 12) = 0.5.

b) A score that is 18 points below the mean corresponds to a z-score of  (-18 / 12) = -1.5.

2.

a) To find the score that represents the 75th percentile for the raw scores, we can use the standard normal table or the Z-table. Since the raw scores form a normal distribution with a mean of 50 and a standard deviation of 4, we can standardize the scores to find the corresponding z-score.

The 75th percentile corresponds to a z-score of 0.67 (by using the standard normal table or the Z-table).

So the raw score that represents the 75th percentile is (0.67 * 4) + 50 = 52.68

Note: Percentile rank is a way to describe the relative standing of a value within a distribution, it's the percentage of values that are equal to or below the value in question.

Answer:

The slope-intercept form of the equation of a line is y = mx + b, where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).

Given a point (x1, y1) and a slope m, we can use the point-slope form of the equation of a line which is:

y - y1 = m(x - x1)

In this case, the point is (5, 12) and the slope is 3/5.

So the equation of the line in point-slope form is:

y - 12 = (3/5)(x - 5)

To put this equation in slope-intercept form, we need to solve for y.

To do this, we can add 12 to both sides:

y = (3/5)x + (12 - (3/5)*5)

y = (3/5)x + 12 - 3

y = (3/5)x + 9

So the equation of the line that goes through the point (5, 12) with the slope m = 3/5 in slope-intercept form is y = (3/5)x + 9

Answer:

Lets plug them in!

9, -3

9 is x

-3 is y

-3 = -9 + 6

-9 + 6 = -3

-3 = -3 okay so far this is looking good! Its a solution to the first one

9 - 3(-3) = 18

9 + 9 = 18

18 = 18

Its this one :)

Step-by-step explanation:

The only point that is a solution to the system of linear equations is; (1, 3).

An equation is an expression that shows the relationship between two or more numbers and variables.

Starting with the first point (9, -3),

y = -x + 6

y = -x + 6

The answer (9, -3) cannot be used.

The point (6,1) now:

y = -x + 6

1 = -6 + 6

Since this is untrue, the answer (6, 1) cannot be used.

The points (1,3) now:

y = -x + 6

3 = -1 + 6

Now we have

6x - 3y = 18

6(1) - 3(3) = 0

Since this is untrue, the (1, 3) cannot be used.

The point (-1, 6) last.

y = -x + 6

6 = 1 + 6

Now we have

6x - 3y = 18

6(-1) - 3(6) = -30

As a result, there is only one point that can be used to solve the system of linear equations: (1, 3).

Answer:

To solve the equation, one needs to have the same type of terms on one side and the constants on the other side, and then using algebraic operations, isolate the variable that you want to find the value of.

For example, starting with the first equation "x = -9y" , if we assume y = 2 and we substitute that value in the equation, we can find the value of x.

x = -9*2 = -18

Then you can use the second equation to check if the value of x and y that you have found are correct by substituting the values into the equation and see if it holds true.

2(-18) - 7(2) = 44, which is true.

Hence the solution of the equation is x = -18 and y = 2.

Answer:

x = -36   and y = 4
