Answer:
The fraction or percentage of the applicants that we would expect to have a score of 400 or above is 77.34%
Step-by-step explanation:
Scores are normally distributed with a mean of 460 and a standard deviation of 80. For a value x, the associated z-score is computed as , therefore, the z-score for 400 is given by
. To compute the fraction of the applicants that we would expect to have a score of 400 or above, we should compute the probability P(Z > -0.75) = 0.7734, i.e., the fraction or percentage of the applicants that we would expect to have a score of 400 or above is 77.34%
Answer:
(i)
(ii)
(iii) $36.5
Step-by-step explanation:
Given that:
1. Total Number of fruits = 80
2. Number of mangoes = x
3. Both mangoes and oranges are there in the basket.
Solution (i):
Only mangoes and oranges are there in the basket and the basket is full.
so, Number of mangoes + Number of oranges = Total number of fruits
x + Number of oranges = 80
Number of oranges =
Solution (ii):
<u>Given:</u>
Cost of an orange = 50 cents = $0.50
Cost of a mango = 40 cents = $0.40
Cost for x mangoes =
Cost for () oranges =
Solution (iii):
Put value of x = 35 in S(x)
Hence, answers are:
(i)
(ii)
(iii) $36.5
