The probability of hitting the area of the shaded region is 0.21 (in the form of two decimal places) when you throw a dar.

The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

We have been given that the radius of the circle = 2cm

So one side of square = 2+2 = 4cm

Area of circle = πr² = (3.14) ×(2)²= (3.14)×4 = 12.57cm²

Area of square = (a)² = (4)² =16cm²

Then the area of the shaded region = 16−12.57 = 3.43cm²

So the probability of hits in the shaded region = 3.43/16 = 0.2144

Round to the nearest Hundredth (two decimal places).

The probability of hits in the shaded region = 0.21

Hence, the probability of hitting the area of the shaded region is 0.21 (in the form of two decimal places) when you throw a dar.

The magnitude of the vector JK is estimated to be  2√13.

The given vector JK's direction is - Ф = 33.69° (angle lies in the fourth quadrant with having direction in clockwise)

The algebraic demonstration of the coordinate-based distances between two points (in coordinate system). Using rectangular coordinates, the Pythagorean theorem is employed to determine distances among points in 2- and 3-dimensional Euclidean space.

Now, in answer to your questioning;

J and K have coordinates of (8,1) & (2,5), respectively.

The following is the distance formula for the points J & K:

JK² = (x₂ - x₁)² + (y₂ - y₁)²

JK = √[(x₂ - x₁)² + (y₂ - y₁)²]

The given of coordinates of J and K's  are-

(x₁,y₁) = (8,1)   and (x₂,y₂) = (2,5).

Substituting the given values in the distance formula;

JK = √[(2 - 8)² + (5 - 1)²]

JK = √[(-6)² + (4)²]

JK = √[36 + 16] = √52

JK  = 2√13 (magnitude of the vector JK)

Now, estimate the vector JK's direction.

The angle formed by a vector with a horizontal line defines its direction.

Use one of the given equation to find the direction of a vector.

tan Ф = Δy/Δx

Where, x = horizontal change

and, y = vertical change

tan Ф = (y₂ - y₁)/(x₂ - x₁)

        = (5 - 1)/(2 - 8)

tan Ф = 4/(-6) = -2/3

Ф = 33.69° (angle lies in the fourth quadrant with having direction in clockwise)

As a result, the distance between J and K is found to be 2√13, that is the same as a magnitude of the given vector JK.

The value of z varies jointly with w and y.

What is the constant of proportion?

A constant of proportion is illustrated as the ratio which relates two given quantities with each other in the relationship of proportion. Constant of proportion is also called constant variation, rate of change, and constant ratio.

Solving for the value of constant of variation

let k be the constant of proportion

When a quantity varies directly with others, then we have a relation, y = kx

Given relation is z = kxy        —-- 1

Also x varies directly with w i.e. x = k'w, where k' is constant of variation for x and w

Using in equation 1, we have,

z = k(k'w)y

z = kk'wy

z = Kwy, where K is constant of variation i.e. K = kk'

It shows that z varies directly with w and y.

Hence, z varies jointly with w and y.

Step-by-step explanation:

The equation in slope-intercept form is y = -2/3x + 6

Given,

Points (x, y) = (6, 2)

Parallel to y = -2/3x + 1

Now,

Recall that a parallel line to the one given has to have the same slope. The slope of the line given is "-2/3" (the coefficient that accompanies "x").

Therefore the equation of a parallel line has to be of the form:

y = -2/3x + b

2 = -2/3(6) + b

2 = -12/3 + b

2 = -4 + b

b = 6

B. The percentage of standardized test scores that is less than 210 or greater than 840 is 0.3%.

C. The percentage of standardized test scores that is greater than 735 is 2.2%.

a) The z score for 210 will be:

= (210 - 525)/105

= -3

The score for 840 = (840 - 525)/105 = 3

Hence,

Percentage between 210 and 840 will be:

= P(-3 < z < 3)

= 99.7%

b) The percentage of standardized test scores is less than 210 or greater than 840 will be:

= 100% - P(Between 210 and 840)

= 100% - 99.7%

= 0.03%

c) The z score for 735 = (735 - 525)/105

Using translation concepts, the new coordinates of the point are given as follows:

(-2.5, 9.8).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x). Examples are shift left, shift right, shift down, shift up, vertical stretching, horizontal stretching, vertical compression, horizontal compression, reflection over the x-axis, reflection over the y-axis, and rotations by a determined amount(in degrees). All these translations have predetermined rules that we apply to the figures.

For this problem, the translation rule for each point is given as follows:

(x, y) → (x - 7.5, y + 6.8)

This translation rule means that the figure is shifted:

The original coordinate is given by:

(5,3), meaning that x = 5 and y = 3.

The local gym holds three 45-minute workout sessions and two 30-minute sessions each week. Then the, total number of minutes Judy worked out for the week was 155 minutes.

We are to determine the total number of minutes Judy worked out for the week.

The gym holds three 45-minute workout sessions and two 30-minute sessions each week

So,

We can write,

The total number of minutes the gym holds workout sessions is

3 × 45 + 2 × 30

= 135 + 60

= 195 minutes

Also, from the information,

Judy left 5 minutes early during the 30-minute sessions and 10 minutes early during the 45-minute sessions.

The total number of minutes Judy didn't attend is

= 3 × 10 + 2 × 5

= 30 + 10

= 40 minutes

Then,

The total number of minutes Judy worked out for the week was,

= 195 minutes - 40 minutes

= 155 minutes

Therefore,

The total number of minutes Judy worked out for the week was 155 minutes.

A system of equations can be solved using:

The given system of equations is:

8y + 10 = 6x   ..... (1)

8y - 4x = -12   ...... (2)

Re-arrange equation (1) to

8y - 6x = -10   ........ (3)

To eliminate variable y, subtract equation (3) from equation (2):

8y - 4x = -12

8y  - 6x = -10 –

      2x  = -2

         x = -1

Substitute  x = -1 into equation (2)

8y - 4x = -12

Step-by-step explanation:

The speed of the faster car is 15 miles per hour.

Two cyclists, 80 miles apart, start riding toward each other at the same time.

One cycles 3 times as fast as the other. If they meet 4 hours later

speed = distance  / time

distance = speed × time

let

speed of the slower cycle = x

speed of the faster cycle = 3x

Therefore,

4x + 3x(4) = distance

4x + 3x(4)  = 80

4x + 12x  = 80

16x  = 80
