In Δ JLP, m ∠ JMP = 3x - 6, JK = 3y - 2, and LK = 5y - 8 then the value of LK = 7.

The median is the value that separates the upper and lower halves of a data sample, population, or probability distribution. It is sometimes referred to as "the middle" value in a data set.

The middle number is discovered by sorting all data points and selecting the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).

Since [tex]$\overline{P K}$[/tex] is a median, JK = KL.

3y - 2 = 5y - 8

simplifying the above equation, we get

3y - 5y - 2 = 5y - 5y - 8

-2y - 2 = -8

Adding 2 on both sides of the equation

-2y - 2 + 2 = -8 + 2

-2y = -6

y = 3

Substitute the value of y in LK, then we get

LK = 5y - 8

= 5(3) - 8

= 15 - 8

LK = 7

Therefore, the value of LK = 7.

The  triangle formed by joining three points on the graph is isosceles triangle

To find out the type we need to find the length of each side which can be found out with distance formula =√[tex](x2-x1)^{2}[/tex]+[tex](y2-y1)\^{2}[/tex] ) provided in the coordinate geometry

so, the length of side PQ of triangle PQR = √[tex](4-2)^{2}[/tex])+[tex](2-5) ^{2}[/tex])

   = √[tex]2^{2}[/tex] +[tex](-3)^{2}[/tex]

                          = √4+9

                           = √13 units

So, the length of side QR of triangle PQR =  √[tex](7-4)^{2}[/tex]+[tex](4-2)^{2}[/tex] )

   = √[tex]3^{2}[/tex] + [tex]2^{2}[/tex]

                          = √(9+4)

                           = √13 units

So, the length of side PR of triangle PQR = √([tex](7-2)^{2}[/tex]+[tex](4-5)^{2}[/tex] )

   = √([tex]5^{2}[/tex] + [tex](-1)^{2}[/tex] )

                          = √(25+1)

Independent events are the ones whose occurrence is unrelated to any other event.

Dependent events include those that are dependent on previous events.

If the probability of an event A occurring is not impacted by the occurring of some other event B, then A & B are referred to as independent events.

Consider the example of a die roll. If A is the event 'the number appearing is odd' and B is the event 'the number showing up is a multiple of 3,'

P(A) = 3/6 = 1/2

P(B) = 2/6 = 1/3

A and B are also the events 'the number showing up is odd & a multiple of 3', implying that;

P(A ∩ B) = 1/6

P(A│B) = P(A ∩ B)/ P(B) = 1/2

Then P(A) = P(AB) = 1/2, implying that the happening of event B has had no effect on the probability of occurring of event A.

Dependent events include those that are dependent on previous events. The outcomes of previous events have an impact on these events. Dependent events are two or maybe more events that are dependent on one another.

When two events, A and B, are interdependent, the probability of their occurrence is:

P(A and B) = P(A) · P(B|A)

Answer: the circle is not a function

the square is a function

Step-by-step explanation:

The diameter of a circle is defined as being twice the length of its radius.

If SU = 16.2 centimeters then the value of RT = 8.1 cm.

The diameter of a circle is defined as being twice the length of its radius. The radius of a circle is measured from the center to one of the circle's endpoints, whereas the diameter is measured from one end of the circle to another end of the circle, passing through the center.

In geometry, a circle's diameter is any straight line segment that passes through the center of the circle and has endpoints on the circle. It is also referred to as the circle's longest chord. Both definitions apply to a sphere's diameter.

The diameter is twice the radius because the greatest distance between two points on a circle must be a line segment through the center of the circle.

Here, SU is the diameter and RT is the radius.

Radius of the circle = 1/2 d

Where d = 16.2 then

substitute the value of d in the above equation, and we get

Radius of the circle  = 1/2 (16.2)

Radius of the circle = 8.1

Hello!

Simplify the expression by combining like terms.

The simplified expression is 4.

The simplified form of the given expression is 4.

To solve the expression 10y + 12 - 7y - 8 - 3y,

We need to combine like terms and simplify.

Simplify the expression by combining the like terms (the terms that have the same variable and the same exponent).

We have 10y, -7y, and -3y,

Which can be combined to give us a total of 0y.

This means that the variable y has been eliminated from the expression.

Combine the constant terms (the terms that don't have a variable or that have a variable raised to the power of 0).

We have 12 and -8, which can be combined to give us 4.

So, the simplified expression is 4.

We can express this mathematically as follows:

10y + 12 - 7y - 8 - 3y = (10y - 7y - 3y) + (12 - 8)

                                 = 0y + 4 = .

The orthocenter of the ΔABC is ( -1,5 ).

In a right triangle, the orthocenter is the polygonal vertex of the right angle. When the triangle's vertices and orthocenter are joined, any point becomes the orthocenter of the other three points, according to Carnot (Wells 1991). These four locations thus form an orthocentric system.

Given the  co-ordinates A( -3,3 ), B( -1,7 ) and C( 3,3 ).

To find the orthocenter using below steps:

1. First, we find the equations of AB and BC.

The general form of a line is y = mx + b

where m is the slope and b is the y-intercept.

Using the formula of slope given [tex]$m =\frac{y_2 - y_1}{x_2 - x_1}[/tex]  , we will find the slope of AB and BC.

Now, slope of AB is m = (7-3/-1 + 3)  

i.e. m = (4/2) = 2

Putting this 'm' in the general form and using the point B(-1, 1), we get the y-intercept as,

y = mx + b

1 = 2 × (-1) + b

i.e. b = 3.

So, the equation of AB is y = 2x + 3.

Also, slope of BC is m=(3-7/3+1)  i.e. m=-4/4 i.e. m--1

Putting this 'm' in the general form and using the point B( -1,1 ), we get the y-intercept as,

y = mx + b i.e. 1 = (-1) × (-1) + b i.e. b = 0.

So, the equation of BC is y = -x.

2. We will find the slope of line perpendicular to AB and BC.

When two lines are perpendicular, then the product of their slopes is -1.

So, slope of line perpendicular to AB is [tex]m*2=-1[/tex]  i.e. m = -1/2

So, slope of line perpendicular to BC is  i.e.[tex]m*-1=-1[/tex] i.e. m = 1.

3. We will now find the equations of line perpendicular to AB and BC.

Using the slope of line perpendicular to AB m=-1/2 i.e.  and the point opposite to AB

i.e. C(3, 3), we get,

y = mx + b

i.e. [tex]3=-1/2*3+b[/tex]  

i.e. b = 9/2

So, the equation of line perpendicular to AB is

[tex]y=-x/2+9/2[/tex]

Again, using the slope of line perpendicular to BC i.e. m = 1 and the point opposite to BC

i.e. A( -3,3 ), we get,

y = mx + b

i.e. 3 = 1 × -3 + b

i.e. b = 6.

So, the equation of line perpendicular to BC is y = x+6

4. Finally, we will solve the obtained equations to find the value of (x, y).

As, we have y = x + 6 and  y = -x/2 + 9/2

This gives, y = -x/2 + 9/2 → x + 6

y = -x/2 + 9/2

simplifying the above equation, we get

2x + 12 = -x + 9

3x = -3

x = -1.

So, y = x + 6

simplifying the above equation, we get

y = -1 + 6

y = 5.

The value of x = -1 and y = 5.

Hence, the orthocenter of the ΔABC is ( -1,5 ).

Answer:

Total Money = $ 75.00

Step-by-step explanation:

Let X be the Total Money

Amount Spent for Shopping = 2/3 of X = 2X/3

Money Lost = 3/5 of (X -2X/3) = 3/5 of (3X-2X)/3 = 3X/15 = X/5

Balance in hand = $ 10.00

is X - 2X/3 - X/5 = $ 10.00

LCM of 3 and 5 = 15

ie (15X - 10X - 3X)/15 = $ 10.00

(15X - 10X - 3X) = 150.00

2X = $ 150.00

X = $ 150.00/2

X = $ 75.00

Using proportions, the costs are given as follows:

a) Total Labor Cost: $2,505,600.

b) Total Product Cost: $1,950,000.

c) Total Cost = $4,455,600.

d) Cost per home = $461.77.

e) Cost per week = $99,013.33.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

For item a, the labor cost is found using the earnings of the workers, as follows:

45 weeks x 5 days x 8 hours x 58 per hour x (12 + 8 + 4 workers)

Hence:

Total Labor Cost = 45 x 5 x 8 x 58 x 24 = $2,505,600.

For item b, the product cost is the cost of the boards, hence:

(175 + 150 + 50 boards) x 5,200

Total Product Cost = 375 x 5,200 = $1,950,000.

For item c, the total cost is the sum of the product cost and the labor cost, hence:

Total Cost = 2,505,600 + 1,950,000 = $4,455,600.

For item d, the cost per home is found dividing the total cost by the 9,649 homes, hence:

Cost per home = 4455600/9649 = $461.77.

For item e, the cost per week is found dividing the total cost by the 45 weeks, hence:
