Answer:

Population of bacteria at  time t = 6 is 2441

Step-by-step explanation:

The complete question is

If y = 10 (2.5)^trepresents the number of bacteria in a culture at time t, how many will there be at time t = 6

Solution

Given

The population of bacteria after time t is equal to y = 10 (2.5)^t

Population when at time t = 6

We will substitute the value of time in above equation.

y = 10 (2.5)^6\\y = 10  *244.14\\y = 2441.4 = 2441

Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were all
Sergio039 [100]
Let events
A=Nathan has allergy
~A=Nathan does not have allergy
T=Nathan tests positive
~T=Nathan does not test positive

We are given
P(A)=0.75  [ probability that Nathan is allergic ]
P(T|A)=0.98  [probability of testing positive given Nathan is allergic to Penicillin]

We want to calculate probability that Nathan is allergic AND tests positive
P(T n A)

From definition of conditional probability,
P(T|A)=P(T n A)/P(A)
substitute known values,
0.98 = P(T n A) / 0.75
solving for P(T n A)
P(T n A) = 0.75*0.98 = 0.735

Hope this helps!!

During the summer, Breanna works at a coffee shop. She saves 75% of her earnings to buy new school clothes. If Breanna earns $75
Westkost [7]

Answer: The best estimate for the amount of money she saves to buy clothes = $ 562.5

Step-by-step explanation:

Given: Breanna saves 75% of her earnings to buy new school clothes.

Earnings for Breanna = $ 750

The amount of money she saves to buy clothes = 75% of 750

= 0.75 x  750   [75%= 0.75]

= $ 562.5

Hence, the best estimate for the amount of money she saves to buy clothes =  $ 562.5
