Coral reef = 0.15x
0.15(11) = 1.65
1 meter = 100 cm
1.65 * 100 = 165
Solution: 165 cm
Answer:
Step-by-step explanation:
we are given opposite and adjacent
we want to figure out x°
remember that,
where our opp is 5 and adj is 12.5
let be x°
so
by using calculator
hence,
our answer is a
Answer:
a) P(X≥143)=0
b) This contradicts the study as getting a sample with this proportion is almost impossible (if the proportion of 68% is true).
Step-by-step explanation:
If we use the normal approximation to the binomial distribution we have the following parameters (mean and standard deviation):
Then, we can calculate the probability of X being equal or more than 143 using the z-score:
This contradicts the study as getting a sample with this proportion is almost impossible (if the proportion of 68% is true).
