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:
n=-2
Step-by-step explanation:
(2n−8)(−2)=24
(2n)(−2)+(−8)(−2)=24(Distribute)
−4n+16=24
−4n+16−16=24−16
−4n=8
Answer:
(x + y)^2 = 45
Step-by-step explanation:
= 40 + 5 = 45
5/9-3/8+(-1/4)+1 4/9+1 5/8=3
The 3 inside angles of a triangle need to equal 180 degrees.
Since you are given 2 angles, subtract both of those from 180 to find X.
X = 180 - 70 - 30 = 80 degrees.
X = 80
