Answer: the answer is that causation cannot be determined from an observational study.
Step-by-step explanation:
Using proportions, considering the cost of the taxi per mile, it is found that Gary traveled 9.375 miles, not including the first.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, the company charges 2.95 for the first mile and $0.3 per each 1/8 mile next = $2.4 per mile. After the first mile, he was charged a total of $25.45 - $2.95 = $22.5. Hence the number of miles is given by:
22.5/2.4 = 9.375.

Answer: If the wall is 300 meters long, the dimensions of the fence with the maximum area will be 300 × 150 = 45000 m²
Step-by-step explanation:
try combinations in a chart
190 × (600-190)/2 = 38950 = 190 × 205 increasing area
200 × (600-200)/2 = 40000 = 200 × 200
220 × (600-220)/2 = 41800 == 220 × 190
240 × (600-240)/2 = 43200 == 240 × 180
260 × (600-260)/2 = 44200 == 260 × 170
280 × (600-280)/2 = 44800 . == 280 × 160
<u>300 × (600-300)/2 = 45000 == 300 × 150</u> Maximum Area
310 × (600-310)/2 = 44950 . == 310 × 145 decreasing area
320 × (600-320)/2 = 44800 . == 320 × 140
Answer: 2 2/3
Step-by-step explanation:
we have to turn this into a improper fractions first (so its something like a bobble-head)
(2 2/5) 5 x 2 = 10 + 2 = 11/5
(3 1/4) 3 x 4 = 12 + 1 = 13/4
Then add those two.
11/5 + 13/4
11 + 13 = 24
5 + 4 = 9
so now its time to put it in simplest form 8/3
Now 8 divided by 3...BUT WAIT...3 can't go into 8
Now we turn it into a Mixed Number 2 2/3
