The updated median is 56.37 and the updated IQR is 17.66.

The median is the value in the middle of a data set, meaning that 50% of data points have a value smaller or equal to the median and 50% of data points have a value higher or equal to the median. For a small data set, you first count the number of data points (n) and arrange the data points in increasing order.

Given that, one employee recorded the measurements for the lengths of 55 different wood boards.

Median =58.37 and IQR=19.66

Someone discovers the measuring tape used started at 2 inches instead of 0.

The interquartile range is given by the difference between the 75th percentile(value that is greater than 75% of the measures) and the 25th percentile.

This means that each piece of wood is actually 2 inches shorter than the value recorded by the employee.

This means that the length of each wood is less than 5. However, the difference between the 75th percentile and the 25th percentile will stay the same, since both were subtracted by 2.

So, IQR=19.66-2 =17.66

Therefore, the updated median is 56.37 and the updated IQR is 17.66.

Step-by-step explanation:

The average speed is 42 km/hr.

To calculate the average speed, you divide the total distance by the time it took to travel that distance:

189 km / 4.5 hours = 42 km/hr

[tex]\texttt{speed}=\dfrac{d}{t}[/tex]

distance = 189 km

time = 4.5 hours

We can use the proportional method in this question

This case is a direct proportion

Direct proportion is a type of proportionality relationship. For direct proportion, as one value increases, so does the other value and conversely, as one value decreases, so does the other value. The symbol ∝ represents a proportional relationship.

We put the variable as x that represents the hour

We put it into a fractional form

[tex]\frac{312}{13} = \frac{x}{12}[/tex]

Cross Multiplying

[tex]312X12 = 13x[/tex]

[tex]3744 = 13x[/tex]

[tex]\frac{3744}{13} = x[/tex]

[tex]288\frac{0}{13} = x[/tex]

The exponential equation is y = 2700 ( 1 + 0.17 )ⁿ , where n = t , the number of hours since the start of the study

The exponential growth or decay formula is given by

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( t ) is the value at time t

x₀ is the initial value at time t = 0.

r is the growth rate when r>0 or decay rate when r<0, in percent

t is the time in discrete intervals and selected time units

Given data ,

Let the exponential equation be represented as y

Now , the number of bacteria cells = y

The number of hours since the start of the study = n = t

The initial number of bacteria = 2,700 cells

The percentage of increase in the cells = 17 %

So , The exponential growth formula is given by

x ( t ) = x₀ × ( 1 + r )ⁿ

Substituting the values in the equation , we get

y = 2700 ( 1 + 0.17 )ⁿ

On simplifying the equation , we get

y = 2700 ( 1.17 )ⁿ

where n = t , the number of hours since the start of the study

Hence , the equation is y = 2700 ( 1.17 )ⁿ

The area of a triangle is given by half the multiplication of the base length by the height of the triangle.

Applying the Pythagorean Theorem, we can obtain the missing side length, as follows:

4² + x² = 6²

x = square root of 20

x = 4.47.

For a right triangle, one side is considered the height of the other, hence the sides are:

7. m<2 = 138° based on the definition of vertical angles.

8. m<3 is supplementary to angle 8

9. The measure of angle 2 = 50°

10. The value of x = 20

A supplementary angle is a pair of angles whose sum is equal to 180 degrees. In other words, two angles are supplementary if they add up to a straight angle.

For example, if one angle measures 70 degrees, its supplement would be 180 - 70 = 110 degrees.

7. m<2 = 138° (reason: vertical angles are equal).

8. m<3 is supplementary to angle 8 because angle 3 and 5 are supplementary, and angle 5 is congruent to angle 8.

9. 5x + 55 = 2x + 100 (corresponding angles are equal)

Find x:

5x - 2x = -55 + 100

3x = 45

x = 15

m<2 = 180 - (5x + 55) (linear pair is equal to 180 degrees)

Plug in the value of x

m<2 = 180 - (5(15) + 55)

m<2 = 180 - 130

m<2 = 50°

10. 45 + 5x + 35 = 180 (supplementary angles)

5x + 80 = 180

5x = 180 - 80

5x = 100

When triangle ABC is dilated to triangle A'BC then the line A'B' has the equation 2z+ 3y = 10.

Parallel lines are any two or more lines that all lie in the same plane and never cross one another. They are equally spaced apart and have the same incline. No matter how far we extend a parallel line, it will never meet another parallel line.

The differentiation of the f(x) = g(x)/h(x), using the quotient rule, indicates that the value of f'(2) = 20/81

The Quotient Rule for finding the derivative of a ratio of two functions, [tex]f(x) = \frac{g(x)}{h(x)}[/tex] that are differentiable is presented as follows;

[tex]f'(x) = \frac{h(x) \cdot g'(x) - g(x) \cdot h'(x)}{h(x)^2}[/tex]

The equation of the lines are found as follows;

The points on the line g(x) are; (1, 2), and (3, 6)

Therefore, we get;

Slope of the line = (6 - 2)/(3 - 1) = 2

Equation of the line is; y - 2 = 2·(x - 1) = 2·x - 2

y - 2 = 2·x - 2

y = 2·x - 2 + 2 = 2·x

The equation of the line is presented as follows;

g(x) = 2·x

Points on the graph of the function h(x) when x = 2 are; (2.5, 5), and (0, 2.5)

Slope of the graph of h(x) when x = 2 is; (2.5 - 5)/(0 - 2.5) = 1

The equation of the line is therefore; y - 5 = 1·(x - 2.5) = x - 2.5

y - 5 = x - 2.5

y = x - 2.5 + 5 = x + 2.5

h(x) = x + 2.5

f(x) = g(x)/h(x)

The value of f'(x) using the quotient rule, is therefore;

f'(x) = (h(x)·g'(x) - g(x)·h'(x))/(h(x))²

g'(x) = 2

h'(x) = 1

Therefore;

f'(x) = ((x + 2.5)×2 - 2·x  × 1)/(x + 2.5)² = (2·x + 5 - 2·x)/((x + 2.5)²)

(2·x + 5 - 2·x)/((x + 2.5)²) = 5/(x + 2.5)²

Answer: Let's call the length of the rectangular court "L" and the width "W". Then, the perimeter of the court is 2 * (L + W) = 148 feet, so 2 * L + 2 * W = 148 feet.

And, according to the coach's estimate, the athlete ran a total of 4 * L + 7 * W = 353 feet.

We can use these two equations to find the dimensions of the court. Solving the first equation for W:

W = (148 - 2 * L) / 2.

Substituting this expression for W into the second equation:

4 * L + 7 * (148 - 2 * L) / 2 = 353

Expanding and simplifying the right side of the equation:

4 * L + 74 - 7 * L = 353

-3 * L = -279

L = 93 feet.

Finally, using the expression for W from the first equation:

W = (148 - 2 * L) / 2 = (148 - 2 * 93) / 2 = 32 feet.

So the dimensions of the sports court are 93 feet by 32 feet.
