Answer:

z = 156

Step-by-step explanation:

y² = 65²-25² = 4225 - 625 = 3600

(x+25)²-65² = z²

x²+50x+625-4225 = z²

x²+50x-3600 = z²    ....(1)

x²+60² = z²

x²+3600 = z²   ....(2)

(1)-(2): 50x - 7200 = 0

50x = 7200

x = 144

check: x² + y² = z²       144² + 60² = 24336 = z²       z = 156

(25+144)²-65² = z² = 28561 - 4225 = 24336            z = 156

In a recent test, you scored 1.0 standard deviations above the average score attained, and the scores are normally distributed.
sesenic [268]

Answer:

97.75 %

Step-by-step explanation:

You score 1 standard deviation above the mean

a) we have from left tail up to the mean 50 % of all values

b) We have in the interval  [ μ  -  σ  ;  μ  +  σ ] 95.5 % of all possible values, if we divide that 95.5 by 2 we get 47.75 %,  the part of the values that correspond to the right, then in order to get the  % of students scored lower we add

50  +  47.75   = 97.75 %

So you can say that the porcentage of students that scored lower than you is 97.75 %
