the age of Jane is 80% of the age of Alice. If we add both ages the result is 45. Find the age of Jane and Alice
inysia [295]

Answer:

Age of Alice=25 years

Age of Jane=20 years

Step-by-step explanation:

We are given that the age of Jane is 80 % of the age Alice.

We have to find the age of Jane and Alice.

Let x be the age of Alice

According to question

Age of Jane=80% of Alice=80% of x=\frac{80}{100}\times x=\frac{4x}{5}

x+\frac{4x}{5}=45

\frac{5x+4x}{5}=45

\frac{9x}{5}=45

x=\frac{45\times 5}{9}=25

Age of Alice=25 years

Age of Jane=\frac{4}{5}\times 25=20 years

Age of Jane=20 years

a country's population in 1990 was 134 million. in 2000 it was a 139 million. estimate the population in 2014 using the exponent
yuradex [85]
F=ir^t

139=134r^10

139/134=r^10

r=(139/134)^(1/10) then:

f=134(139/134)^(t/10)  so in 2014, t=24 so

f=134(139/134)^(2.4)

f≈146 million  (to nearest million)

Some will say that you have to use the exponential function, but it really gives you the same answer...even for continuous compounding :)...

A=Pe^(kt)

139=134e^(10k)

139/134=e^(10k)

ln(139/134)=10k

k=ln(139/134)/10 so

A=134e^(t*ln(139/134)/10)  when t=24

A=134e^(2.4*ln(139/134))

A≈146 million (to nearest million)

The only real reason or advantage to using A=Pe^(kt) is when you start getting into differential equations...

Answer:

(d) there is not enough information to tell if this is a biased sampling method.

Step-by-step explanation:

Based on reviews we cannot conclude whether the sampling is biased or not, if only we can know the total number of times the taxi was ordered then we can conclude.
