Same line so the correct answer is b
Answer and explanation
a is $18.00 because Z is a constant
b is y=2.50x+18.00
c is that y=2.50x+z turns into y=$55.50 and then x=15 which we substitute
that leads to 55.50 =2.50(15)+z
and the untimely z = 18.00 dollars .
Answer:
The cost of extracting the first 50 tons of copper is $151,000.

For the 50 tons of cooper.
So
1 thousand dollars.
So

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
Answer:
The value of x any y are "-5.29 and 0.79" and "3.79 and -2.29"
Step-by-step explanation:
Given values:
After solve equation (a) we get
After solve equation (b) we get
put the value of x in to equation (x)
The value of y is = -5.29 and 0.79, put the value of y in x1 equation so, we get: 3.79 and -2.29
