Answer:
Two standard deviations
Step-by-step explanation:
The Z score is obtained using the mean and standard deviation, according to the empirical. Rule, which gives percentage of values that lie within an interval estimate in a normal distribution ;
one standard deviation lie within 68% of the mean
Two standard deviations lie within 95%
Three standard deviations lie within 99.7%
Hence, for the question given, 95% fall within 2 standard deviations of the mean
Step-by-step explanation:
given length of hypotenuse, h=3 units.
adjascent angle for x is 45°
cos(45°)=x/3
cos(45°)=1/root 2(I dont have root symbol sorry)
1/root 2=x/3
x=3/root 2 units
x=3root 2/2
and hi pls comment
