A town has a population of 12000 and grows at 3.5% every year. What will be the population after 7 years, to the nearest whole n
1 answer:
Answer:
After 7 years the population will be 15268.
Step-by-step explanation:
Given a town has a population of 12000 and grows at 3.5% every year. we have to find the population after 7 years.
As the general growth formula is
where A = Amount after growth
P = Original amount
r = yearly growth rate
t = no. of years
here, P=12000, r=0.035, t=7
=
=
Hence, after 7 years the population will be 15268.

For the 99th percentile, we have X = 206 seconds.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
99th percentile:
Value of X when Z has a pvalue of 0.99. So we use
For the 99th percentile, we have X = 206 seconds.

(-3, 2)
Step-by-step explanation:
Given that point Q, partitions segment PE, such that PQ:QE is 1:3, coordinates of point Q is found using the formula below:
Where,
Plug in the necessary values to find x and y coordinates for point Q as follows:
The coordinates of the point Q are (-3, 2))
