Answer:
The answer is 
Step-by-step explanation:
If we assume that people cannot taste a difference between bottled water, then the probability of identifying tap water is 0.5
Thus, P(identify tap water)=0.5
The probability that at least 8 of the 9 people identify the tap water correctly is the sum of the probabilities
- 8 of 9 people identified correctly or
- 9 of 9 people identified correctly
Since P(identify tap water)=0.5 each probabilities are the same and equal to
=
So we have 
=
Ok here’s the equation you can run on the next one
A=P(1+rt) A is total P is current amount or starting amount r is annual interest and t is the amount of time
Your answer is
$297.60
Answer:
-2c^2 + c
Step-by-step explanation:
First, expand to make it easier
y=x(x^2+5)(x^2+5)
y=x(x^4+10x^2+25)
y=x^5+10x^3+25x
differentiation
y'=5x^4+30x^2+25 is the derivitive
Answer:
infinite solutions
Step-by-step explanation:
3(n+6)≥3n+8
3n+18≥3n+8 (distributive property)
18≥8 (subtracted 3n from both sides)
this will always be true so there are infinite solutions
