Answer:
<u>If we remove 61 from the data set, the median changes from 87.5 to 93.</u>
Step-by-step explanation:
1. Let's calculate the median of the original data set:
Median = (3rd term + 4th term)/2 because the number of terms are even and our median mark is the average of the two middle marks, in this case, 82 and 93.
Median = (82 + 93)/2
Median = 87.5
2. Let's calculate the median of the data set removing 61:
Median = 3rd term because our median mark is the middle mark, in this case, 93. It is the middle mark because there are 2 scores before it (80 and 82) and 2 scores (94 and 98) after it.
Median = 93
I think the answer is C good luck
10 and 5/100. 5/100 is equal to 0.05, by the definition of decimals, so this turns the expression into 10.05

Answer:</h3>
- slope = 1/2
- equation: y = 1/2x +5
<h3>
Step-by-step explanation:</h3>
Slope
The slope of the line between two points (x1, y1) and (x2, y2) is ...
... m = (y2 -y1)/(x2 -x1)
For your given points, the slope is
... m = (4 -9)/(-2 -8) = -5/-10
... m = 1/2
Equation
The point-slope form of the equation for a line can be written ...
... y = m(x -h) +k . . . . for a line of slope m through point (h, k)
Using the first point given and the slope just calculated, the equation for the line can be written ...
... y = (1/2)(x -8) +9
... y = (1/2)x -4 +9 . . . . eliminate parentheses; next, collect terms
... y = 1/2x +5
