Compute the mean and standard deviation for the sample below, rounding each to the nearest hundredth. 13, 15, 17, 19, 21, 22, 27.
The mean of the sample is
(Type an integer or a decimal. Round to two decimal places as needed.)
The standard deviation of the sample is
(Type an integer or a decimal. Round to two decimal places as needed.)

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
