The answer is
96%.
Explanation:
It is generally presumed that the scores are normally distributed.
1) You are given how many standard deviations from the mean Jeremy's score is. This is exactly the definition of the
z-score. Therefore z = 1.75
2) Look at a left-tail z-table in order to find the area of the normal curve on the left of your z-score (see picture attached). A = 0.9599
3) Multiply the area by 100 in order to find the
percentile:
<span>0.9599 </span>× 100 = 95.99
Therefore, 95.99% of the students scored less than Jeremy.
Hence, the answer is
96%.
You follow the same steps as you would normally, but you can count how many units down it is, instead of how far up.
Answer:
t = 1
Step-by-step explanation:
16 - 2t = t + 9 + 4t
Group like terms
16 - 2t = t + 4t +9
Add similar elements t + 4t = 5t
16 - 2t = 5t + 9
Subtract 16 from both sides
16 - 2t - 16 = 5t + 9 - 16
Simplify
-2t = 5t - 7
Subtract 5t from each side
-2t - 5t = 5t - 7 - 5t
Simplify
-7t = -7
Divide both sides by -7
-7t/ -7 = - 7/ - 7
Simplify
t = 1
Answer: The probability that both televisions work : 0.5329
The probability at least one of the two televisions does not work : 0.4671
Step-by-step explanation:
Given : The total number of television : 11
The number of defective television : 3
The probability that the television is defective : 
Binomial distribution formula :-
, where P(X) is the probability of getting success in x trials, p is the probability of success and n is the total trials.
If two televisions are randomly selected, then the probability that both televisions work:

The probability at least one of the two televisions does not work :
