Consider two data sets A and B. The sets are identical except the high value of the data set B is three times greater than the high value of data set A.
a) How do the median of the two data sets compare?
(b) How do the means of the two data sets compare?
(c) How do the standard deviations of the two data sets compare?
(d) How do the box- and –whisker plots of the two data sets compare?

Answers
The median of the two data sets compares as they will be the same.
How is the median illustrated?The medians are the same because the median is the value such that 50% of the data points are higher and 50% are lower. Therefore, the actual value of the highest element doesn't affect the median.
The mean of set B is greater and the standard deviation of B is higher because the highest element is further from the mean. Also, the boxes are the same if the center line is the median since the interquartile range is the same.

At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 11 m. The inner edge of the sidewalk is a circle with a radius of 9 m.
(a) Write and simplify an expression for the exact area of the sidewalk.
(b) Find the approximate area of the sidewalk. Use 3.14 to approximate π.
Answers
A) Area of the sidewalk = R^2 - r^2 - This can be the expression
B) = 3.14
=(R^2-r^2)
=(11^2-9^2)
=(121-81)
=*40
That was the simplified expression
Answer = 3.14 * 40 = 125.6m^2

Find an equation of the tangent line to the curve at the given point. y=√x, (49,7) To find the equation of a line, we need the slope of the line and a
Answers
Answer:
The equation of the tangent line to the curve at the given point is [tex]y = \frac{1}{14}(x - 49) + 7[/tex]
Step-by-step explanation:
Equation of the tangent line:
The equation of the tangent line to a function f(x) at a point [tex](x_0,y_0)[/tex] is given by:
[tex]y - y_0 = m(x - x_0)[/tex]
In which m is the slope, which is given by the derivative of f(x) at [tex]x_{0}[/tex]
y=√x, (49,7)
This means that [tex]x_0 = 49, y_0 = 7[/tex]
The derivative is:
[tex]y^{\prime} = \frac{1}{2\sqrt{x}}[/tex]
At [tex]x = 49[/tex]
[tex]m = y^{\prime} = \frac{1}{2\sqrt{49}} = \frac{1}{14}[/tex]
So
[tex]y - y_0 = m(x - x_0)[/tex]
[tex]y - 7 = \frac{1}{14}(x - 49)[/tex]
[tex]y = \frac{1}{14}(x - 49) + 7[/tex]
The equation of the tangent line to the curve at the given point is [tex]y = \frac{1}{14}(x - 49) + 7[/tex]
Chila is measuring a triangle. First, she measures the triangle's angles. Each of the triangle's angles is 60 degrees. Next, she measures its sides. Side A is 6 cm long. Side B is also 6 cm long. What is the length of side C?
Answers
Answer:
Side C is also 6 cm long.
Step-by-step explanation:
Given: Each of the triangle's angles is 60 degrees.
Also, side A is 6 cm long. Side B is also 6 cm long.
To find: length of side C
Solution:
A triangle in which each angle is equal to 60 degrees is an equilateral triangle.
As each of the triangle's angles is 60 degrees, the given triangle is an equilateral triangle.
Sides of an equilateral triangle are equal to each other.
As side A is 6 cm long and side B is also 6 cm long,
side C is also 6 cm long.

As per quadratic equation, the solutions to the equation √(x² + 2x - 10) = √(x + 20) is x = - 6, 5.
What is a quadratic equation?"A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0, where 'a' and 'b' are the coefficients(a ≠ 0), x is the variable, and 'c' is the constant term."
The given quadratic equation is:
√(x² + 2x - 10) = √(x + 20)
⇒ (x² + 2x - 10) = (x + 20)
⇒ (x² + 2x - 10) - (x + 20) = 0
⇒ (x² + x - 30) = 0
⇒ (x² + 6x - 5x - 30) = 0
⇒ x(x + 6) - 5(x + 6) = 0
⇒ (x + 6) (x - 5) = 0
⇒ x = - 6, 5

A measurement of 4.5 yards is how many feet longer than a measurement of 132 inches?
Answers
Answer:
4.5X3=13.5, 132/12=11, 13.5-11=2.5
Step-by-step explanation:
A measurement of 4.5 yards is 2.5 feet longer than a measurement of 132 inches.
As we know that,
[tex]1 yard = 3 feet[/tex]
So, 4.5 yards = [tex]3*4.5=13.5feet[/tex]
[tex]12 inch = 1 feet\\\\132inch = \frac{`132}{12}=11feet[/tex]
Difference between 4.5 yards and 132 inches = [tex]13.5-11=2.5feet[/tex]
Thus, the measurement of 4.5 yards is 2.5 feet longer than a measurement of 132 inches.
