Answer:
The first set of expenses is 75% of the second assuming we are in a 30-day month.
Step-by-step explanation:
To find this, we first have to find out how much we spend a month in coffee. To do so, we multiply the daily cost by number of days in a month (we'll use 30 for this case).
$3 * 30 days = $90 a month.
Now to find the percentage, we divide what we spend in coffee by what we spend on gas.
$90/$120 = 75%
F(3)=2(3) -1
f(3)= 6 - 1
f(3)=5
the number is 8 because the equation is (x * 3) + 4 so replace x with (8) and its (8 * 3) + 4 = 28 :)
The IQR is 6.25. The median, the middle of the data is 14.5. In short the answer is 6.25
