Answer:
95.15%
Step-by-step explanation:
We have that the mean (m) is equal to 20, the standard deviation (sd) 3
They ask us for P (x <25)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / sd
We have all these values, replacing we have:
z = (25 - 20) / (3)
z = 1.66
With the normal distribution table (attached), we have that at that value, the probability is:
P (z <1.66) = 0.9515
Which means that the probability that it arrives before 25 minutes is 95.15%
Answer:
TanA= 
and sinA=36/45
Step-by-step explanation:
Tan= opposite/adjacent
since 36 is opposite of A and 27 is adjancent to 36 your will use tanA= 36/27
Sin= opposite/hypotenuse
36 is opposite of A and 45 is the hypotenuse
Answer:
17.7
Step-by-step explanation:
62.3-7=55.3
55.3-19.9=35.4
35.4/2 = 17.7
