Answer:
The probability is 0.8944
Step-by-step explanation:
The probability of Z<1.25 in a normal distribution is
P(Z<1.25) = 0.5 + P(Z<1.25)
P(Z<1.25) = 0.5 + 0.3944
P(Z<1.25) = 0.8944
Hence, the probability of randomly selecting a z-score less than z = 1.25 from a normal distribution is 0.8944

Step-by-step explanation:
Answer:
C ≈ 22.1°
Step-by-step explanation:
The law of cosines formula is given. Solving it for C, we find ...
C = arccos((a^2 +b^2 -c^2)/(2ab))
where a and b are the sides adjacent to the angle.
Then we have ...
C = arccos((14^2 +19^2 -8^2)/(2·14·19)) = arccos(493/532)
C ≈ 22.1°

If you have a fair number of these to do, a spreadsheet is a useful tool. There are also triangle solver apps on the web or your local smart platform that will do this, too.
Well 1000 for his birthday then subtract 25 each week, w, should be 1000-25w if i am not mistaken.
