Answer:
Step-by-step explanation:
Billy and Maria mow lawns. Billy earned $15 the first day and $20 every day after that. This means the if Billy mowed lawns for x days after the first day, the total amount earned by Billy would be
15 + 20x
Maria earned $10 the first day and $25 every day after that. This means the if Maria mowed lawns for y days after the first day, the total amount earned by Maria would be
10 + 25y
To determine how much each earns after 15 days, it becomes
For Billy, x = 15
Amount earned = 15 + 20×15 = $315
For Maria, y = 15
Amount earned = 10 + 25×15 = $385
Maria earns more than Billy
Answer:
POISSON DISTRIBUTION
Step-by-step explanation:
When dealing with the number of occurrences of an event over a specified interval of time or space, the poisson distribution is often useful.
Poisson distribution is applicable if:
The probability of the occurrence of the event is the same for any two intervals of equal length.
The occurrence or nonoccurrence of the event in any interval is independent of the occurrence or nonoccurrence in any other interval.
The probability that two or more events will occur in an interval approaches zero as the interval becomes smaller.
Therefore, the appropriate probability distribution is POISSON PROBABILITY DISTRIBUTION.
Answer:
a) T(r) = r.D(r)
b) 975 people per square mile.
Step-by-step explanation:
(a)
The units of D(r) are
when multiplying the density by the area we get the amount of people in that area, so
(b)
The average rate of change of T(r) over the interval [5,7] is
but D(7) = 350 and D(5) = 100, so
and the average rate of change of T(r) over the interval [5,7] is 975 people per square mile.
I believe it is 7.875. If you want it simplified it would be 8 ounces. Please give me brainliest!
