Using the binomial distribution, the mean number of balls you would expect him to catch is of 7.2.

It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.

The expected value of the binomial distribution is:

E(X) = np

For this problem, the parameters are:

n = 8, p = 0.9.

Hence the mean is:

E(X) = np = 8 x 0.9 = 7.2.

The width of rectangle is 15 feet and the length of rectangle is 23 feet.

According to the statement

Width of rectangle = x

Length of rectangle = x+10

Area of rectangle = 345 sq-feet.

we know that the area of rectangle is

Area of rectangle = L*W

Substitute the values in it then

345 = (x) (x+8)

345= (x)^2 + 8x

(x)^2 + 8x - 345 = 0

By factorisation

(x-15) (x+23) = 0

So, width of rectangle is 15 feet and the length of rectangle is 23 feet.

The perimeter of the rectangle that has a length of 5 3/5 inches, and the width as half of its length is 16.8 inches. Hence, option A is the right choice.

The perimeter of any object is the total sum length of its boundary.

The perimeter of a rectangle with length l units and width w units is given as:

Perimeter = 2(l + w) units.

In the question, we are given that the length of a rectangle is 5 3/5 inches and its width is half of its length. We are asked to find the perimeter of the rectangle.

The length of the given rectangle (l) = 5 3/5 inches = 28/5 inches.

The width of the given rectangle (w) = Half of length = 1/2 * 28/5 inches = 14/5 inches.

Thus, the perimeter of the rectangle = 2(l + b) = 2(28/5 + 14/5) inches,

or, the perimeter = 2(42/5) inches,

or, the perimeter = 84/5 inches,

or, the perimeter = 16.8 inches.

Thus, the perimeter of the rectangle that has a length of 5 3/5 inches, and the width as half of its length is 16.8 inches. Hence, option A is the right choice.

The given question is incorrect. The correct question is:

"The length of a rectangle is 5 3/5 inches. the width of the rectangle is half of its length. what is the perimeter of the rectangle?

(a) 16.8 inches

(b) 8.4 inches

Answer:

Step-by-step explanation:

a) it is a reflection

b) it is vertex B"

Answer:

36 in.

Step-by-step explanation:

find the area of the rectangle and triangle first

area of rectangle = length x height

aR = (6 + 6) x 5

aR = 12 x 5

aR = 60

area of triangle = base x height x 1/2

aT = (6 + 6) x 4 x 1/2

aT = 12 x 4 x 1/2

aT = 24

now, to find the area of the shaded area subtract the triangle from the rectangle

area = rectangle - triangle

a = 60 - 24

a = 36

Based on the information, Christian would have $5525.5 of annuity.

According to given information, the number of coffees per week is 3 then, per month is 3x4 = 12

For each coffee is $4.5. Then monthly expenditure for coffees is 12 x 4.5 = $54

Rate of interest r = 1.6% = 1.6/100 = 0.016 and for monthly compounding r = 0.016/12 = 0.00133

n = number of payments = 8 x 12 = 96

We can use the formula for finding the future value as below

FV = C x [ ( 1 + r )n-1 ] / ( r )

FV = 54 x [ ( 1 + 0.00133 )96 – 1 ] / (0.00133)

= 54 x [ (1.13609 - 1)] / (0.00133)

= 54 x 0.13609 / (0.00133)

= 54 x 102.3233

Parabolas are graphs that make U-shapes and are formed from quadratic equations.

Vertical Parabolas

There are 2 different types of parabolas: vertical and horizontal.

If the x-value is squared, then the parabola is vertical. So, this graph must open up or down.

Positive A-Value

The a-value is the coefficient before the squared term. In a vertical parabola, the graph opens up if the a-value is positive. On the other hand, the graph opens down when the a-value is negative.

In this case, the graph is a vertical parabola that opens up. This means that the range will have a minimum value but no maximum.

On the train, there are a total of 125 children.

Total number of passengers = 500

Out of 500 passengers, men =7/20

So, the number of men= 500* 7/20 = 175

Out of 500 passengers, women = 40%

So, the number of women passengers = 500*40/100 = 200

Therefore, the total number of men and women passengers= 175+200 = 375.

There are also children on the train. So, the rest number should be those children.

The rest number =children= 500- 375 = 125.

So, it is concluded from the above equation that there are 125 children on the train.

Pi is a Greek number that plagues mathematics, physics, and circles to the point where pi-fatigue is actually a thing. Pi is an infinite number, however it will henceforth only be written as 3.14159.

I have two solutions to your problem.

The first, and probably less appealing answer, but most used everywhere, would be to use a calculator.

But if you find yourself without a calculator at the ready, I hope you’re prepared to math quite dubiously.

Finding the square power, inverse of a radical, or whatever is multiplied by itself to equal 3.14159, is the second step. We must start someplace to start our attempt, and that place is 3.14159. Since 1 squared equals 1 and 2 squared equals 4, our result, expressed in decimal form, is larger than 1 but less than 2. After that, we just start divising and multiplying the decimals again until we have calculated the square root of pi.

  C.  f(x) = 2x⁴ +6x³ +22x² +54x +36

Step-by-step explanation:

You can use Descartes' rule of signs and the y-intercept to help you select the correct answer.

The given point (0, 36) is the y-intercept of the function. This tells you 36 is the constant in the polynomial, eliminating choices A and B.

Descartes' rule of signs tells you the number of positive real roots will be less than or equal to the number of sign changes in the coefficients when the function is written in standard form. The number of negative real roots will be the number of sign changes after the signs of odd-degree terms are reversed.

The given real roots are both negative. There are zero positive real roots, so all of the signs of the coefficients in the function must be the same (no changes). This eliminates choice D, and tells you C is the correct answer.

According to the question,

Cost of 1 bag of lemons = $x

Cost of 8 bags of lemons = 8*x = 8x

Cost of 8 bags of lemons = Total cost - cost of the egg

8x = $39.62 - $6.74

Answer:

Step-by-step explanation:

70 = x/4

x = 4 cos 70 = 1.37m

x = 4 cos  80 = 0.69m  

The range is ( 0.69m, 1.37m)

The range of distances from the wall (x) that the foot of the ladder  placed to fall within the safety guidelines is between 0.7052 meters and 1.456 meters.

To determine the range of distances from the wall that the foot of the ladder may be placed to fall within the safety guidelines,  use trigonometry.

Let's assume the distance from the wall to the foot of the ladder is x meters the ladder is 4 meters long.

The angle between the ladder and the ground is given to be between 70° and 80°. Let's consider the extreme cases for each angle:

When the ladder makes an angle of 70° with the ground:

In this case, the angle between the wall and the ladder (θ) will be 90° - 70° = 20°.

When the ladder makes an angle of 80° with the ground:

In this case, the angle between the wall and the ladder (θ) will be 90° - 80° = 10°.

Now, use trigonometry to calculate the range of distances (x) from the wall:

For the first case (θ = 20°):

tan(20°) = Opposite / Adjacent

tan(20°) = x / 4

x = 4 × tan(20°)

For the second case (θ = 10°):

tan(10°) = Opposite / Adjacent

tan(10°) = x / 4

x = 4 × tan(10°)

Now, let's calculate the values:

x ≈ 4 × 0.3640 ≈ 1.456 meters (rounded to three decimal places) - for the first case.

x ≈ 4 × 0.1763 ≈ 0.7052 meters (rounded to four decimal places) - for the second case.

Answer:

Step-by-step explanation:

51 + 4x + 7 = 90 - combine like terms

58 + 4x = 90 - subtract 58 from each side

4x = 32 - divide both sides by 4

x = 8

Answer:

x = 8

Step-by-step explanation:

The red square indicates that there is a right triangle. All right triangles have angles equal to 90°. Therefore, we can find the value of "x" by setting the sum of both the interior angles to 90°.

(4x + 7) + 51° = 90°                                  <----- Sum of both angles is 90°

4x + 58 = 90°                                          <----- Combine 58 and 7

4x = 32                                                    <----- Subtract 58 from both sides

x = 8                                                        <----- Divide both sides by 4
