Answer:
a square
Step-by-step explanation: because a square has all four right angles and also a square can turn into a rectangle, but a rectangle can't turn into a square.
Calculate the median of the following data 18, 24, 55, 59, 34, 39, 22, 32, 57, If 55 is replaced by 33, calculate the new median

The median with the number how they are and not being replaced is 37.7 with the 55 being replaced with 33 the new median is 35.3
Answer:
The answer is below
Step-by-step explanation:
Yosune walked her dog 5 miles today and plans to walk her dog 2.5 miles every day from now on. The total number of miles walked y can be represented by y = 2.5x + 5, where x is the number days walked after today. a. State the x- and y-intercepts and then graph the equation. b. Interpret the x- and y-intercepts.
Solution:
The equation for a linear function is given by:
y = mx + b; where m is the slope of the function and b is the y intercept.
Given the equation y = 2.5x + 5, the y and x intercept can be found by substituting x = 0 and y = 0. Hence:
a) x intercept is the value of x when y = 0. Therefore:
0 = 2.5x + 5
2.5x = -5
x = -2
y intercept is the value of y when x = 0. Therefore:
y = 2.5(0) + 5
y = 5
b) The x-intercept is at the point (–2, 0). But there cannot be a negative number of days walked, hence the x intercept does not apply in this situation.
The y intercept is at the point (0, 5). This means that Yosune has initially walked her dog 5 miles.
The way you tell whether a value is a solution or not is to try it in the equation.
A. -4*7 +2 = -26 ≠ 26 . . . . not a solution
B. -4*6 +2 = -22 ≠ 26 . . . . not a solution
C. -4*-7 +2 = 30 ≠ 26 . . . . not a solution
D. -4*-6 +2 = 26 = 26 . . . . this is your solution
_____
Of course, you can also solve the equation.
.. -4x +2 = 26
.. -4x = 24 . . . . . . subtract 2 (the term that doesn't contain x)
.. x = -6 . . . . . . . . .divide by -4 (the coefficient of x)
