sorry if i didnt get the 2nd one right i tired tho
mark brailiest please
:)
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
Dolls : teddy bears
6 : 7
if 120 dolls are equal to 6 portions,
7 portions,
(120/6) * 7
140 teddy bears
The next larger tenth is 10.1 .
The next smaller tenth is 10.0 .
10.04 is nearer to 10.0 than it is to 10.1 .
So the nearest tenth is 10.0 .
