Answer:

The probability that a particular firm selected has $1 million or more in income after taxes is 49%.

Step-by-step explanation:

We are given a study of 200 computer service firms revealed these incomes after taxes below;

         Income After Taxes                  Number of Firms

           Under $1 million                              102

      $1 million up to $20 million                    61

           $20 million or more                          37      

                 Total                                           200    

Now, the probability that a particular firm selected has $1 million or more in income after taxes is given by;

Total number of firms = 102 + 61 + 37 = 200

Number of firms having $1 million or more in income after taxes = 61 + 37 = 98  {here under $1 million data is not include}

So, the required probability =  \(\frac{\text{Firms with \$1 million or more in income after taxes}}{\text{Total number of firms}}\)

                                           =  \(\frac{98}{200}\)

                                           =  0.49 or 49%

The probability that a particular firm selected has $1 million or more in income after taxes is 0.49 or 49%.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

A study of 200 computer service firms revealed these incomes after taxes:

Income After Taxes Number of Firms Under

$1 million 102

$1 million up to $20 million 61

$20 million or more 37.

Then the total event will be

Total event = 102 + 37 +61 = 200

The probability that a particular firm selected has $1 million or more in income after taxes will be

Favorable event = 37 + 61 = 98

Then the probability will be

\(\rm P = \dfrac{98}{200} \\\\P = 0.49 \ or \ 49 \%\)

Equivalent equations are algebraic equations that have identical solutions or roots.

Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation.

Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.

The first step is to know the rules of equivalent equations:

Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation.

Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.

Raising both sides of the equation to the same odd power or taking the same odd root will produce an equivalent equation.

If both sides of an equation are non-negative, raising both sides of an equation to the same even power or taking the same even root will give an equivalent equation.

The values of the piecewise function is g(1) = 3, g(2) = 1 / 2, g(3) = 1 / 4.

Piecewise functions are functions consisting in two or more expression constrained by intervals. In this case, we find a piecewise function formed by three equations. In this exercise we need to evaluate the function, whose expression depends on the x-value to be used. There are three values to be evaluated:

x = 1

g(1) = (1 + 1)² - 1

g(1) = 2² - 1

g(1) = 4 - 1

g(1) = 3

x = 2

g(2) = - (1 / 4) · 2 + 1

g(2) = - (1 / 2) + 1

g(2) = 1 / 2

x = 3

g(3) = - (1 / 4) · (3) + 1

g(3) = - (3 / 4) + 1

g(3) = 1 / 4

The value of x is 2 and the perimeter of the square is 3 and perimeter of the triangle is 2.

Given that,

The equilateral triangle and the square have the same perimeter.

The side of the triangle is 2x-2 and the side of the square is 2.5x-3.

We have to find the value of x.

We have,

Triangle's perimeter is equal to the square's perimeter.

2.5x-3= 2x-2

2.5x-2x=-2+3

0.5x=1

x=1/0.5

x= 2

The perimeter of the square is 2.5(2)-3=5-2=3

The perimeter of the triangle is 2(2)-2=4-2=2

Step-by-step explanation:

Based on the information given, we have a diagram with two sides labeled as 13.3 mm and 5.5 mm, and another side labeled as X mm.

To find the length of X, we can use the fact that the sum of the lengths of the sides of a triangle is equal to the perimeter.

Perimeter = 13.3 mm + 5.5 mm + X mm

The perimeter is the total distance around the triangle. Since we have three sides, the perimeter is the sum of the lengths of those sides.

To find X, we can subtract the sum of the known sides from the perimeter:

X mm = Perimeter - (13.3 mm + 5.5 mm)

Since the value of X is not given, we cannot calculate it without the perimeter value. If you provide the perimeter value, I can help you find the length of X.

Answer:

2(x² + 5)

Step-by-step explanation:

To factor 2x² + 10, we can first factor out the greatest common factor of the terms, which is 2:

2x² + 10 = 2(x² + 5)

We can't factor anymore, so the answer is:

2(x² + 5)

Answer:

2(x² + 5)

Step-by-step explanation:

To factorise this, do the distributive property backwards. In other words:

2x² + 10

2x² ÷ 2 + 10 ÷ 2

x² + 5

2(x² + 5)

∴ 2(x² + 5) is the answer

Answer:

  x = 9 inches

Step-by-step explanation:

You want the value of x in the similar triangles shown.

Corresponding sides are proportional. This means the ratio of the horizontal side of the triangle to the vertical side is the same for both.

  6/4 = (6+x)/10

  15 = 6 +x . . . . . . . . multiply by 10

  9 = x . . . . . . . . . subtract 6

The measure of x is 9 inches.

Additional comment

You could also write the proportion ...

  6/4 = x/(10 -4)

  x = 36/4 = 9 . . . . . . . multiply by 6

You can see this if you draw a horizontal line through the figure at the top of the side marked 4 in.

Answer:

10.5 mph

Step-by-step explanation:

To find the constant of proportionality in miles per hour, we need to divide the distance (in miles) by the time (in hours) for each of the two runs, and then take the average of the two rates.

For Monday's run:

Rate = Distance / Time = 21 miles / 3 hours = 7 miles per hourFor Wednesday's run:Rate = Distance / Time = 10 1/2 miles / 1 1/2 hours = (21/2) miles / (3/2) hours = 14 miles per hour

To find the average rate, we add the two rates and divide by 2:Average rate = (7 miles per hour + 14 miles per hour) / 2 = 10.5 miles per hour

Therefore, the constant of proportionality in miles per hour is 10.5. This means that Ashley runs at an average rate of 10.5 miles per hour during her training.

While an absolute value may be any number, the output from an absolute value expression is always greater than or equal to zero

The absolute value | x | of a real number x is defined as the non-negative value of x without regard to its sign. For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3. The absolute value of a number may be thought of as its distance from zero along real number line.

The absolute value of any number is seen to be always greater than or equal to zero. Both a number and its opposite are the same distance from zero on the number line. Since they have the same distance from zero, they have the same absolute value.

Answer:

8575 joules

Step-by-step explanation:

We have that the volume is given as follows:

v = 7 * 1 * delta x

v = 7 * delta x

we know that the density: mass / volume

therefore the mass is:

mass = volume * density

replacing:

mass = 7 * delta x * 1000

mass = 7000 * delta x [kg]

now we know that force equals mass * acceleration:

F = 7000 * delta x * 9.8 m / s ^ 2

F = 68600 * delta x [N]

Now, we multiply by x meters, to calculate the work:

W = F * x

W = 68600 * delta x * x

W = 68600 * delta x [J]

We know that the portion of the chian x to x + delta x to be the following

limit when n tends to infinity of the sum of i = 1 up to n = infinity of 68600 * xi * delta x

therefore, the total work done to pump half of the water out of the aquarium is:

To the integral of 68600 * x * dx from 0 to 1/2, applying the integral we have:

68600 * x ^ 2/2 [x = 0 to x = 1/2]

68600 * ((1/2) ^ 2) / 2 - 68600 * (0 ^ 2) / 2 = 8575

That is to say that the work is 8575 joules
