The bacteria grow from <span>1,000 bacteria into 12,500 bacteria in 12 hours. The exponent function would be:
an= ao(1+r)^t
12.500= 1,000(1+r)^12
1,000(12.5)= 1,000(1+r)^12
</span>12.5= (1+r)^12
1+r= 1.23427
r= 0.23
Number of bacteria after 20hr would be:
an= ao(1+r)^t
an= 1,000(1+0.23)^20
an= 1,000(62.821 <span>)
an= </span><span>62,821 </span>
Answer:
3/16
Step-by-step explanation:
Answer:
(b) 0.251
Step-by-step explanation:
1. Standard deviation equation:
Where X is the mean of the data, and N the amount of data. Then, N=5
2. Estimate the Mean:
3. Caclulate Standard deviation:
Answer:
x=8 x=-8
Step-by-step explanation:
-3|x|=-24
Divide each side by -3
-3|x|/-3=-24/-3
|x|=8
There are 2 solutions a positive and a negative
x=8 x=-8
