Answer:
P(120< x < 210) = 0.8664
Step-by-step explanation:
given data
time length = 20 year
average mean time μ = 165 min
standard deviation σ = 30 min
randomly selected game between = 120 and 210 minute
solution
so here probability between 120 and 210 will be
P(120< x < 210) = 
P(120< x < 210) = 
P(120< x < 210) = P(-1.5< Z < 1.5)
P(120< x < 210) = P(Z< 1.5) - P(Z< -1.5)
now we will use here this function in excel function
=NORMSDIST(z)
=NORMSDIST(-1.5)
P(120< x < 210) = 0.9332 - 0.0668
P(120< x < 210) = 0.8664
Answer:
Step-by-step explanation:
we are given two temperature
4 degrees and -10 degrees
since it says to figure out the changed
substract
remove parentheses and change its sign
simplify addition:
and we are done!
The first step would be :
E) 3x + (2x + 4) = -7
Answer:
sinx = p/h , cosx = b/h , tanx = p/b
you can use these relations
Step-by-step explanation:
p = perpendicular = side opposite to the angle
h = hypotenuse = side opposite to the right angle
b= base
if no angles are given, p and b can be interchanged
Step-byiioiiiiiioiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
