What is the equation for exponential growth in Biology?

1 answer:

8 0

The exponential growth in biology is A=Pert, where "A" is the ending amount of whatever you're dealing with , "P" is the beginning amount of that same "whatever", "r" is the growth or decay rate, and "t" is time. The formula is related to the compound-interest formula, and represents the case of the interest being "compounded continuously".

All our answers lie in the above statement.

Confidence Level:
The creator claims that 9 out 10 students will have the average score in the said range. Or in other words we can say that the creator is 90% confident about the result of the field test. So the confidence level is 90%.

Margin of Error:
The average score lies within 4% of 70%. This means the margin of error is 4% i.e. the average scores can deviate from 70% by 4% .

Confidence Interval:
Lower Limit = 70% - 4% = 66%
Upper Limit = 70% + 4% = 74%

Interpretation:
The exam creator is 90% confident that the average scores of seniors will be between 66% and 74%.

Can you help me please

igor_vitrenko [27]

Answer:

Step-by-step explanation:

ΔA = 90° - 31°

= 59°

sin A = perpendicular ÷ base

sin 59° = 400 ft ÷ y

1.6643 = 400 ft ÷ y

y = 400 ÷ 1.6643

y = 240.34 ft

How do I solve 1 1/2c = 6

quester [9]

$1 \frac{1}{2} c = 6 \\ \\ \frac{2 + 1}{2} c = 6 \ / \ convert \ to \ improper \ fraction \\ \\ \frac{3}{2} c = 6 \ / \ simplify \\ \\ \frac{3c}{2} = 6 \ / \ simplify \\ \\ 3c = 6 \times 2 \ / \ multiply \ each \ side \ by \ 2 \\ \\ 3c = 12 \ / \ simplify \\ \\ c = \frac{12}{3} \ / \ divide \ each \ side \ by \ 3 \\ \\ c = 4 \ / \ simplify \\ \\$

So, your answer to this problem is c = 4.

Step-by-step explanation:

First factor out the negative sign from the expression and reorder the terms

That's

$\frac{1}{ - (( \tan(2A) - \tan(6A) )} - \frac{1}{ \cot(6A) - \cot(2A) }$
