Answer:
The sample size is
Step-by-step explanation:
From the question we are told that
The lower bound of the range is a = 51
The upper bound of the range is b = 710
The margin of error is
Generally the standard deviation is mathematically represented as
=>
=>
From the question we are told the confidence level is 95% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of is
Generally the sample size is mathematically represented as
=>
=>
Answer:
C) 3/1
Step-by-step explanation:
Take the ratio of the corresponding sides.
FD =2 is the side of ΔDEF with the known length, corresponding side of ΔABC is AC = 6
<u>The ratio is:</u>
Correct choice is C
The exponential growth function is P(t) = 6.38 million x (1.0238^t).
The population of the city in 2018 is 7.35 million.
The year the population would be 9 million is 14.46 years.
The doubling time is 29.12 years.
<h3>What is the exponential growth function?</h3>
FV = P (1 + r)^n
- FV = Future population
- P = Present population
- R = rate of growth
- N = number of years
6.38 million x (1.0238^t)
Population in 2018 = 6.38 million x (1.0238^6) = 7.35 million
Number of years when population would be 9 million : (In FV / PV) / r
(In 9 / 6.38) / 0.0238 = 14.46 years
Doubling time = In 2 / 0.0238 = 29.12 years

Answer:
Option A) The sum of x and y is a rational number
Step-by-step explanation:
we know that
A <u>rational number</u> is a number that can be written as a ratio or quotient of two integers
so
In this problem we have
Is a rational number, because the number can be written as a ratio or quotient of two integers
