Answer:
Bacterial population at the time of 10 hours = 1040000
Step-by-step explanation:
Let the function that defines the bacterial population after 'x' hours is,
p(x) = a(b)ˣ
Where a = Initial population
And 'x' = Duration or time
Since bacterial population is getting doubled every hour,
2a = a(b)¹
b = 2
Therefore, function will be,
p(x) = a(2)ˣ
From the graph attached,
Point (5, 32500) lies on the graph of the function.
32500 = a(2)⁵
a = 
Therefore, the function will be,
p(x) = 1015.625(2)ˣ
For x = 10 hours,
p(10) = 1015.625(2)¹⁰
= 1040000 bacteria
Answer:

567 is the answer because of the 7percent
Answer: z= 1.51
Step-by-step explanation:
Test statistic for proportion is given by :-
Where n is sample size ,p is the sample proportion , P Is the population proportion and Q =1 - P.
Given : P=57% = 0.57
Q= 1- P = 1-0.57=0.43
n = 25
Test statistic for proportion will be :-
We should report the value of test statistic z= 1.51
Answer:
1/170
Step-by-step explanation:
divide 12 by 2040
Answer:
(a) c = 40h + p
(b) $285
Step-by-step explanation:
(a)
Total Cost = (Cost per hour x Number of Hours) + Total Cost of Parts
c = 40h + p
(b)
For this case, p = $165 and h = 3:
c = 40*3 + 165 = $285
