Answer:
1) 0.1667
2) 0.8333
3) 1
Step-by-step explanation:
Let A be the event that 3 is observed on the first trial.
Let B be the event that at least two trials are required to observe a 3
a) A six-sided die has 6 possible outcomes of 1,2,3,4,5,6
3 is one of the six possible outcomes
P(A) = no of favourable outcomes /no of possible outcomes
P(A) = 1/6 = 0.1667
b) The event of requiring at least two trials to observe a 3 is the event of not observing a 3 on the first trial.
P(B) = P(A')
P(A')= 1 - P(A)
P(B) = 1 - 1/6
= 5/6 = 0.8333
c) P(AnB) = P(A) + P(B)
= 1/6 + 5/6
= 6/6 = 1
If depreciation is 7.25% per year, then the common factor is (1-0.0725), or 0.9275.
Thus, the car's value after 5 years will be:
V = $28000(0.9275)^5 = $28000(0.6864) = $19218.86, or (to the nearest dollar) $19218 (answer)
Answer:
Step-by-step explanation: yes because when rewritten in standard form the x term will still be raised to the 2nd power.
Answer:
So, the question means that if we add the number of tiger shark teeth and the sand shark teeth and subtract it from the total number of teeth, we will get the number of bull shark teeth. And, the number of bull shark teeth is 4.
Step-by-step explanation:
So, the question means that if we add the number of tiger shark teeth and the sand shark teeth and subtract it from the total number of teeth, we will get the number of bull shark teeth.
Since Christian has 18 shark teeth, and 6 are tiger shark teeth, 8 are sand shark teeth and the rest are bull shark teeth.
Let x represent the number of bull shark teeth.
So, total number of shark teeth = number of tiger shark teeth + number of sand shark teeth + number of bull shark teeth.
18 = 6 + 8 + x
18 = 14 + x
subtracting 14 from both sides, we have
18 - 14 = 14 - 14 + x
4 = 0 + x
4 = x
x = 4
So, the number of bull shark teeth is 4.
