Answer:
The percentage lost is 5.3%
Answer:
57
Step-by-step explanation:
Given that :
Standard deviation (σ) = 5 minutes = (5 *60) = 300 seconds
Margin of Error, E = 78
Assume a confidence interval of 95%;
Using the relation :
((Zα/2 * σ) / E)²
(1 - α)/2 = (1 - 0.95)/2 = 0.05 /2 = 0.025
Z0.025 = 1.96
Sample size = ((1.96 * 300) / 78)²
Sample size = (588 / 78)^2
Sample size = 7.5384615^2
Sample size = 56.828
= 57 samples
Answer:
Slope=3
Step-by-step explanation:
y2-y1/x2-x1
13-2/0-5
13-2=-15
0-5=-5
-15/-5 negative/negative=positive
3
Exercise 1:
The exponents are wrong: when you divide two power, you subtract the exponents:
Exercise 2:
The function represents a growth rate of 300%! 3% is actually written as 0.03, so the correct function is
Exercise 3:
To factor a quadratic equation, we have to find the roots. Once you have the roots 
, you can factor the expression as 
In this case, the solutions are 
, which yields the factorization
Exercise 4:
When you multiply two powers of the same base, you add the exponents:
So, in your case, you have
Answer:
1/2.
Step-by-step explanation:
f(x) = (1/8)^x
when x = 1/3
f(x) = (1/8)^1/3
f(x) = ∛(1/8)
f(x) = 1 / ∛8
f(x) = 1/2.
