Mateo is culturing bacteria that have a growth rate of 5.3% per hour. If the current population is 38,762 bacteria, how many bac

Taya2010 [7]

..Given:

$\begin{gathered} a=38762 \\ r=5.3\%=\frac{5.3}{100}=0.053 \\ t=20 \end{gathered}$

To Determine: The number of bacteria after 20 hours

Using the future value formula for growth rate

$\begin{gathered} P_a=P_c(1+r)^t \\ P_a=(Bacteria,final,population) \\ P_c(Bacteria,current,population)=38762 \\ r(rate)=0.053,t(time,in,hour)=20 \end{gathered}$

Therefore

$\begin{gathered} P_a=38762(1+0.053)^{20} \\ P_a=38762(1.053)^{20} \\ P_a=38762(2.809101) \\ P_a=108886.39 \\ P_a\approx108886 \end{gathered}$

Hence, population of bacteria in 20 hours is 108,886

The weights of a sample of college textbooks has a bell-shaped distribution with a mean of 8.1 p o u n d s ( l b s ) and a stand

weeeeeb [17]

Answer:

The interval ( 1,8 ; 14,4 ) will contains 99,7 % of all values

Step-by-step explanation:

For Normal Distribution N ( μ ; σ ) the Empirical Rule establishes that in the intervals:

( μ ± σ ) we find 68,3 % of all values

( μ ± 2σ ) we find 95,4 % of all values

( μ ± 3σ ) we find 99,7 % of all values

Then we have a normal distribution N ( 8,1 ; 2,1 )

3*σ = 3* 2,1 = 6,3

And 8,1 - 6,3 = 1,8 8,1 + 6,3 = 14,4

Then the interval ( 1,8 ; 14,4 ) will contains 99,7 % of all values
