Look back at your notes if you have any.
Price of boots is represented as x, price of tennis shoes is represented as y.
x-y=44.38
x+y=196.12
Isolate x. (Or y, if you wanted to)
x=y+44.38
x=196.12-y
Set them equal to each other.
y+44.38=196.12-y
Solve for y. Then plug it in to either of the two original equations to find x.
x=120.24
y=75.86
Note: This is assuming that the boots are more expensive than the tennis shoes. If the tennis shoes are more expensive than the boots, then the prices would be switched. I didn't find this clear in your question.
Answer:
Step-by-step explanation:
The difference in fixed cost is $9; the difference in per-mile cost is $0.02. The difference in per-mile cost will equal the difference in fixed cost for a distance of ...
$9.00/($0.02/mi) = 450 mi
At that distance, the rental cost is ...
$50 +450×$0.15 = $50 +67.50 = $117.50
Both plans will cost $117.50 for 450 miles of driving.
61/66=0.9242 So in % that is %92.42
Answer:
Step-by-step explanation:
Experimental probability is the ratio of the number of times an event occurs to the total number of trials or times the activity is performed.
Theoretical probability is a method to express the likelihood that something will occur. It is calculated by dividing the number of favorable outcomes by the total possible outcomes.
Experimental: 38 times occurred/ 100 trials = 38/100 = 38%
Theoretical: 1/2 chance a coin lands on heads, 1/2 chance a coin lands on tails. 1/2 = 50%
Onne depends on chance, and one on facts, they are different.
Experimental Probability can vary for flipping a coin
Theoretical Probability will always be 50%
