probability is a measure of the chance of an event to arise. Many activities can't be expected with total fact. we will predict handiest the chance of an event to occur i.e. how possibly they are to happen, using it

probability is the department of mathematics regarding numerical descriptions of ways probably an event is to occur, or how in all likelihood it is that a proposition is genuine. The opportunity of an occasion is various among zero and 1, where, more or less speakme, zero indicates impossibility of the event and 1 suggests truth

Step-by-step explanation:

The side of the smaller triangle has a length of 7, the larger triangle will be:

= (7 × 3)/2

= 10 1/2

Answer:

1/5 = slope of line

Step-by-step explanation:

Here, slope = rise/run = (larger y value) - (smaller y-value)/(larger x -smaller x)

Here we get slope = rise/run = (3 - 2) (4 - [-1]) = 1/5 = slope of line

The value of x is -1 and the values on both sides are the same, hence the equation has infinite number of solution

Linear equations are equation that has a leading degree os 1. Given the equations below:

The answer would be D. 4

because you would multiply the numerator and denominator by the conjugate.

The following weights are listed below:

The sum of the weights of a red circle, a yellow rhombus and a green trapezoid is equal to 35 units.

In this question we find a case of abstract thinking, in which we find a weight system at equilibrium. There are the following variables below:

x - Weight of a red circle.

y - Weight of a purple cross.

r - Weight of an orange star.

u - Weight of a dark blue square.

v - Weight of a yellow rhombus.

w - Weight of a green trapezoid.

z - Weight of a light blue triangle.

And the resulting system of linear equations is:

x + y = 24                                 (1)

y + v = 12                                 (2)

u = 6                                        (3)

2 · r = 6                                    (4)

1.5 · v + 2 · u = 24                    (5)

0.5 · v + w + r + 2 · z = 24       (6)

u = z + 1                                    (7)

By (3):

u = 6

By (4):

r = 3

By (7):

z = 5

And the reduced system of linear equations is:

x + y = 24                                   (1)

y + v = 12                                   (2)

1.5 · v = 12                                  (5)

0.5 · v + w = 11                           (6)

By (5):

v = 8

By (6):

w = 11 - 0.5 · v

w = 11 - 4

w = 7

By (2):

y = 12 - v

y = 12 - 8

y = 4

Answer:

TU = 27

Step-by-step explanation:

ST + TU = SU

(8x - 11) + (14x - 15) = 19x - 17

8x - 11 + 14x - 15 = 19x - 17

22x - 26 = 19x - 17

22x - 19x = 26 - 17

3x = 9

x = 3

TU = 14x - 15 = 14(3) - 15 = 27

By using the trigonometric function of cosine, we conclude that the length of the hypotenuse is approximately equal to 7.2 units.

Right triangles are triangles such that one of its internal angles is a right triangle. Fundamentally, trigonometric functions are relationships between two distinct sides of a right triangle.

The picture show that the length of one leg and the measure of the angle between that leg and the hypotenuse are known, but the length of the hypotenuse does not. By using concepts of trigonometric functions, we can find the length of the hypotenuse by using the cosine function:

cos θ = s / x

cos 33° = 6 / x

x = 6 / cos 33°

x = 6 / 0.839

x ≈ 7.154

The length of the hypotenuse is approximately equal to 7.2 units.

Answer:

Step-by-step explanation:

Answer:

67 units

Step-by-step explanation:

Perimeter  of a shape is the sum of all sides.

Perimeter = a + b + c + d

                = x +7  + 2x + 2 + 8x + x +10

                = x + 2x + 8x + x  +7 + 2 + 10

Combine like terms,

                 = 12x + 19

Now, substitute x = 4 in the above expression,

                  = 12*4 + 19

                  = 48 + 19

                  = 67

The total Commission Buehrer earns is 1404.3.

Given, Commission on first 3000 sales is 5% and commission on next 6000 sales is 8% and the commission she get when done a sales over 12000 is 10%.

She did a total sales of 19743.

Total Commission = (5% of 3000 )+ (8% of 6000)+(10% of (total sale - 12000))

Total commission = (150)+(480)+(10% of (19743-12000))

Total commission = (150)+(480)+(10% of (7743))

Total commission = (150)+(480)+(774.3)

Total commission =1404.3

Hence Total commission she earns for the sales in the month is 1404.3.

The required value of x in the proportion of the line is 9.

Given that,
B is located between points A and C.
AB= x + 2; BC = 2x + 7 and AC = 36

To determine the value of x in the proportion of line.

A line is a straight curve connecting two points or more showing the shortest distance between initial and final points.

Here,
B is the point lies between A and C on line segment AC

So,
AC = AB + BC
AB +  BC = 36
x + 2 + 2x + 7 = 36
3x + 9 = 36

A) The rearranged formula is:

r = d/t

B) Using the above formula we can see that the rate is 25,000 m/h.

C) Here we have the linear equation:

d = (25,000 m/h)*t

Here we need to use the formula:

distance = rate*time.

To solve this formula for the rate, we need to divide both sides by the time, so we will get:

rate = distance/time.

Writing this with the given variables:

r = d/t.

b) Now we know that the distance is 800,000 meters and the time is 4 hours, then the rate will be:

r = 100,000m/4h = 25,000 m/h

The rate is 25,000 meters per hour.

c) Now we wil get the linear equation:

d = r*t

d = (25,000 m/h)*t

Part A:

Rearrange the distance formula, d = rt, to solve for rate. The distance formula is given by d = rt, where d is the distance traveled, r is the rate at which the distance is being traveled, and t is the time taken to travel the distance.
To solve for rate, we can rearrange the formula as follows: d = rt d/t = r [dividing both sides by t] r = d/t

Therefore, the formula for rate is r = d/t.

Part B: Find the falcon's rate in meters per hour. Given that the falcon flies 800,000 meters in 4 hours, we can use the formula for rate to find its speed. r = d/t r = 800,000/4 r = 200,000 meters per hour.

Therefore, the falcon's rate is 200,000 meters per hour.

Part C: Rearrange the distance formula, d = rt, to solve for time. To solve for time, we can rearrange the formula as follows: d = rt t = d/r [dividing both sides by r]

Therefore, the formula for time is t = d/r.

Step-by-step explanation:

The two angles are the same size, and adding them together (15+15) equals 30.

Total charge by company A for 80 sq.feet = 250+10(80)= $1050

Total charge by company B for 80 sq.feet = 90+12(90)=$1170

Let x be the no.of square feet for landscaping

Company A

Monthly consulting fee = $250

Cost of landscaping of 1 sq.feet = $10

Cost of landscaping of x sq.feet = $10x

So, Total charge by company A = 250+10x  ---1

Company B

Monthly consulting fee = $90

Cost of landscaping of 1 sq.feet = $12

Cost of landscaping of x sq.feet = $12x

So, Total charge by company B = 90+12x   ---2

Now we are supposed to find  how many square feet of landscaping will the two companies charge the same amount

So, Equate 1 and 2

250+10x = 90+12x

160=2x

80=x

So, the two companies charge the same amount for 80 sq.feet

Total charge by company A for 80 sq.feet = 250+10(80)= $1050

Total charge by company B for 80 sq.feet = 90+12(90)=$1170

We need to know the concept of mean and standard deviation to solve the problem.The standard deviation of the data set is 18.36

The given dataset is 1,2,3,3,4,4,4,4,5,5,6,70, inorder to find the standard deviation of the data set we need to first find the mean of the dataset. Mean of a dataset means the average of the set of numbers. We divide the sum of all the numbers in the data set by the size of the set. We represent mean by μ.

μ=[tex]\frac{1+2+3+3+4+4+4+4+5+5+6+70}{12} =\frac{111}{12} =9.25[/tex]

Standard deviation measures the dispersion of a dataset relative to it's mean, the square of standard deviation is variance.

The formula for standard deviation is :

σ=[tex]\sqrt{\frac{(1-9.25)^{2}+(2-9.25)^{2} +...+(70-9.25)^{2} }{12} } =\sqrt{\frac{68.0625+52.5625+78.125+110.25+36.125+10.5625+3690.5625}{12} } \\=\sqrt{\frac{4046.25}{12} } =\sqrt{337.1875} =18.36[/tex]
