The growth of Mycobacterium tuberculosis bacteria can be modeled by the function N ( t ) = a e ^ { 0.166t }, where N is the numb

er of cells after t hours and a is the number of cells when t = 0.
a.) At 1:00 P.M. there are 30 M. tuberculosis bacteria in a sample. Write a function that gives the number of bacteria after 1:00 P.M.

b.)Use a graphing calculator to graph the function in part(a).

C)Describe how to find the number of cells in the sample at 3:45 P.M

Answer:

A) y= 30e^(0.116t)

C) 2.75

Step-by-step explanation:

A) You just plug in 30 for a in the original equation

B) Self explanatory

C) The difference between 1 pm and 3:45 pm is equivalent to 2:45 minutes. In this case 45/60(45 mins/hour) is equal to 3/4 which really is .75. The 2 should be the hours so the answer is 2.75

jarptica [38.1K]

Answer:

P(x < 535.8) = 0.64

P_{64} = 535.8

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 500

Standard Deviation, σ = 100

We are given that the distribution of SAT score is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

We have to find the value of x such that the probability is 0.64

P(X<x) = 0.64

P( X < x) = P( z < \displaystyle\frac{x - 500}{10})=0.64  

Calculation the value from standard normal z table, we have,  p(z

\displaystyle\frac{x - 500}{100} = 0.358\\x = 535.8

P(x < 535.8) = 0.64

P_{64} = 535.8

grandymaker [24]

Answer:

A=42000(1.04)^n

Step-by-step explanation:

This is a compound interest formula expressed as:

A=P(1+i)^n

Where:

  • n is time in years
  • i is the rate of interest
  • A is the accumulated amount after n years
  • P is the initial amount.

#We substitute the given values to determine amount after n years as follows:

A=P(1+i)^n\\\\=42000(1+0.04)^n\\\\=42000(1.04)^n

Hence, the amount earned after n years is given by the expression A=42000(1.04)^n

<span>If 100C2 has a value of 4,950, what is the value of 100C98?
10C2 is the number of groups of 2 that can be formed from 100 objects.
Note: Each time a group of 2 is selected you automatically form
a second group of 98. Therefore: 10C2 = 10C98 = 4950 is your Answer</span>
