Answer:
B
Step-by-step explanation:
The data is symmetric, and the three 10 count as outliers.
Thank you! Have a nice day!
Since the price of the cantaloupes is unknown, it will have to represented by a variable. Let's use x.
If Jackson starts with $25 and buys 5 cantaloupes of an unknown price, this subtracts 5 times the amount of 1 cantaloupe (which is x) from that $25.
This is shown as 25 - 5x.
After spending that money, he has $2.50 left over.
This means 25 - 5x = 2.50.
Now you just need to solve this by first isolating the variable.
First, subtract 25 from both sides.
25 - 5x - 25 = -5x
2.50 - 25 = -22.5
Then, divide both sides by -5. It's -5 since 5 is the coefficient and it's negative, so -5.
-5x / -5 = x
-22.5 / -5 = 4.5
This means x = 4.5.
And if x is 4.5, then that means the cost of 1 cantaloupe is $4.50.
Slope = (y2 - y1) / (x2 - x1)
Slope = -26 - (-14) / 8-4
Slope = -12 / 4
Slope = -3
The median is the middle number. To find the median, put the numbers in order of least to greatest.
2,3,4,5,5,5,8
The middle number is the one that is the median. Because there are seven numbers, the exact number in the middle is 5, making it the median.
