Identify the function as exponential growth or decay. y = a * (8/5) ^ 0

sukhopar [10]

Answer:

We conclude that the function represents exponential growth.

Step-by-step explanation:

Given the function

$y=a\left(\frac{8}{5}\right)^t$

As the function is of the form

y=abˣ

and base 'b' > 1

We know that when the base 'b' of the exponential function > 1, meaning those numbers will get bigger, we call it exponential growth.

As b=8/5 is bigger than 1.

i.e. 8/5 > 1

Thus, we conclude that the function represents exponential growth.

We would like to estimate the proportion of UF students who owns a scooter to within 1% of the truth, with 95% confidence. We do

professor190 [17]

Answer:

Option A) 9604

Step-by-step explanation:

We are given the following in the question:

Confidence level = 95%

Standard error = 1%

$p = q = 0.5$

Formula for sample size:

$n = (z_{stat}\times \dfrac{p(1-p)}{\text{Standard error}})^2$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting values, we get,

$n = (1.96\times \dfrac{0.5(1-0.5)}{0.01})^2 = 9604$

Thus, the sample size must be

Option A) 9604
