You take 94.5 and divide by 4.5 get 21
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
Assuming that the cost of the fine is proportionate per each 20mph increase, then a 40mph speeding ticket should be $4, and if they received a fine of $150 would be a crazy amount of speed, is there something you did not attach?
Answer:
True
Step-by-step explanation:
Since babysitting and working at the grocery store are two different things, you would need two different variables.
So x and y would be the correct representation.

Answer:
Answer choice a.
Step-by-step explanation:
Let's do part of the work of solving the given system:
6x + 2y = −6
3x − 4y = −18
Multiply the first equation by 2 so as to make the coefficient of y = to 4:
12x + 4y = -12
Combine this result with the second equation:
12x + 4y = -12
3x − 4y = −18
------------------------
15x = -30
Note that these results are precisely the same as the equations in Answer Choice a.
