Answer:
D(4, 1)
Step-by-step explanation:
The two diagonals have the same midpoint, so ...
(A+C)/2 = (B+D)/2
A+C = B+D . . . . multiply by 2
A+C-B = D . . . . . subtract B
D = (1, 1) + (5, 3) - (2, 3) = (1+5-2, 1+3-3)
D = (4, 1)
Answer:
a) $4,960
b) 8% per annum
c) $120
Step-by-step explanation:
a) 4000 + 960 = $4960
b) 960 ÷ 3 = 320 per year
320/4000 × 100 = 8%
c) 1% more per year:
1% of 4000 = 40
3 years: 120
So $120 more
Answer:
1. P(X=0)=0.135
2. P(T>1)=0.271
Step-by-step explanation:
1. Let X be the number of accidents in the next year. Find the distribution of X and calculate P(X=0).
The rigth distribution to describe this type of event as number of accidents per unit of time is the Poisson distribution.
In this case k=0 accidents, parameter λ=2 events/year and t=1 year:
2. Let T be the amount of time until the next accident. Find the distribution of T and calculate P(T>1).
In this case, the time between events can be best described by an exponential distribution:
In this case parameter λ=2 events/year and t=1 year:
That means it could be + - 3 degrees.
52 + 3 = 55
52 - 3 = 49
The temperature range is 49 to 55
