Answer:

Step-by-step explanation:

The team draws with a probability of 1 = (0.5 + 0.2) = 0.3

If the team does not win then it loses or draws.

Loosing = 0.2

Draw := 0.3

P(not win) = 0.2 + 0.3 = 0.5

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

Not lose means wins or draws.

P(not lose) = 0.5 + 0.3 = 0.8

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

Not Draw means wins or loses

P(not draw) = 0.5 + 0.2 = 0.7

Of course all of these could be done more directly.

P(not win)= (1 - win) = 1- 0.5 = 0.5

P(not lose) =  ( 1 - lose) = 1 - 0.2 = 0.8

P(not draw) = (1 - 0.3) = 0.7

Step-by-step explanation:

2x-12 = 18

    +12  +12

2x=20

20/2 = 10

Answer:

24

Step-by-step explanation:

Original equation:

2x - 12 = ?

We know x = 18

So, just plug the value into the equation

2(18) - 12

Multiply 2 by 18

36

Subtract 12 from 36

The answer is 24

Answer:

8x^2+38x+45 so B

Step-by-step explanation:

i got it right on the test

The required equation of the function that represents the area of the porch is A(x) = 8x² + 38x + 45. Option D is correct.

Given that,
Dan is tiling his rectangular, concrete porch with square, porcelain tiles. The length of the porch is represented by the function l(x)=4x+9, where x is the side length, in feet, of each tile. The width of the porch is represented by the function w(x)=2x+5.

The surface area of any shape is the area of the shape that is faced or the surface area is the amount of area covering the exterior of a 3D shape.

Here,
Length of the porch = 4x + 9
Width of the porch = 2x + 5
area of the porch A(x) = (4x + 9) (2x + 5 )
                                     = 8x² + 20x + 18x + 45
                                     = 8x ² + 38x + 45

Thus, the required equation of the function that represents the area of the porch is A(x) = 8x² + 38x + 45. Option D is correct.

Answer:

Thus, train speed = 70 mph while wind speed is. y = 14 mph

Step-by-step explanation:

Let x = speed of the plane in mph.

Let y = speed of wind in mph.

We are told that The trip there was with the wind. It took 4 hours. The trip back was into the wind. The trip back took 6 hours.

Formula for distance is;

Distance = speed × time

Thus;

(x + y)4 = 336

(x + y) = 84 - - - - (1)

Also;

(x - y)6 = 336

Divide both sides by 6

(x - y) = 56 - - - (eq 2)

Add eq 1 and 2 to give;

2x = 84 + 56

2x = 140

x = 140/2

x = 70 mph

Plug in 70 mAh for x in eq 1.

(70 - y) = 56

y = 70 - 56

y = 14 mph

Thus, train speed = 70 mAh while wind speed is. y = 14 mph

Answer:

5.25×10−3

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:

A. x²/y³

Step-by-step explanation:

Given the following data;

Length = x³y⁴

Width = [tex] xy^{7}[/tex]

Ratio = length/width

[tex] Ratio = \frac{x^{3}y^{4}}{xy{^7}}[/tex]

Simplifying the equation by applying the law of indices (division), we have;

[tex]\frac{x^{3}}{x} = x^{3} - x^{1} = x^{3-1} = x^{2} [/tex]

[tex]\frac{y^{4}}{y^{7}} = y^{4} - y^{7} = y^{4-7} = y^{-3} [/tex]

Hence, rearranging the above values;

[tex] Ratio = \frac{x^{2}}{y^{3}}[/tex]

Therefore, the expression that represents the ratio of the length of the rectangle to the width of the rectangle is A. x²/y³.

if it takes two workers 10 minutes to plant 3 trees,then it will take 4 workers 5 minutes to plant 3 trees.3÷24=8,then 5×8=40

If it takes 2 workers 10 minutes to plant 3 trees then it will take 4 workers 40 minutes to plant 24 trees.

Two or more expressions with an Equal sign is called as Equation.

The rate at which each worker plants trees.

If two workers can plant 3 trees in 10 minutes, then one worker can plant 3/2 trees in 10 minutes

One worker can plant 1.5 trees in 10 minutes, or 0.15 trees per minute.

Now, we can use this rate to find how long it will take 4 workers to plant 24 trees.

Since each worker plants at a rate of 0.15 trees per minute

Four workers will plant at a combined rate of 0.15 x 4 = 0.6 trees per minute.

To plant 24 trees at a rate of 0.6 trees per minute, we can use the formula:

time = (amount of work) / (rate of work)

Plugging in the values, we get:

time = 24 / 0.6 = 40

Therefore, it will take 4 workers 40 minutes to plant 24 trees.
