Answer:
56 7/10
Step-by-step explanation:
convert 40 1/2 to a fraction 40 1/2 = 81/2
multiply both sides by 7/5
this gets w by itself on the left
81/2 x 7/5 = 567/10 = 56 7/10
300 total point
since there r 10 games and 30 points fatal each game then it’s 300
2.500.000 is the answer but I think simplifying it would make it 2.5?
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).
