Answer:
90m
Step-by-step explanation:
AB = 18m
BC = AB + 9 = 18 + 9 = 27m
Perimeter = 2(AB + BC)
= 2( 18 + 27)
= 2 x 45
= 90m
Answer:
$677.18
Step-by-step explanation:
Data provided in the question:
Bill’s nominal income in 1990 = $1,009 per month
CPI value in the year 1990 = 149
CPI value in the year 2017 = 192
Now,
The Consumer price index ( CPI ) is given as :
CPI =
thus,
for the given case of year 1990
149 =
or
Real income in 1990 =
or
Real income in 1990 = $677.18
Volume of cylinder = Base Area x Height
Height = Volume/Base
Height = (6n² -13n -28)/(3n+4)
Perform this division and you will get Height = 2n-7
z-score of a company is 5.
What is z- test?
A z-test is a statistical test used to determine whether two population means are different when the variances are known and the sample size is large.
The annual salaries of all employees at a financial company are normally distributed with a mean of $34,000 and a standard deviation of $4,000.
Now, using z- score
z= (x-)/
z= 54000- 34000/ 4000
z= 20000/4000
z=5.
Hence, z-score of a company is 5.

Answer:
The equation that represents the population after T years is
Step-by-step explanation:
Population in the year 2018 ( P )= 7,632,819,325
Rate of increase R = 1.09 %
The population after T years is given by the formula
-------- (1)
Where P = population in 2018
R = rate of increase
T = time period
Put the values of P & R in above equation we get
This is the equation that represents the population after T years.
