The temperature dropped 12º because if you subtract 12 from 10, you get -2.
Hope this helps!
Answer:
the probability is 69.15%
Step-by-step explanation:
We have that the mean is 38 inches (m) and the standard deviation is 2 inches (sd), so we are asked:
P (x <39)
P ((x - m) / sd <(39 -38) /2)
P (z <0.5)
If we look in the normal distribution table we have to:
P (x <39) = 0.6915
That is, the probability is 69.15%
So bob started at 9:55. you add the 25 minutes from how it took him to mow the front yard to your starting time
9:55 there are sixty minutes in an hour
+:25
10:20 am
then you add the 45 minutes it took him to mow the back yard from that time
10:20 remember there are only sixty minutes in an hour
+ :45
11:05 am
so Bob finished mowing at 11:05am
We can find the interior angle (A) that is associated with the angle of depression using the tangent
tan(A) = 970%2F184
A = 79.3 degrees
therefore
90-79.3 = 10.7 degrees is the angle of depression
1 centigram= 10 milligram
if you convert 25cg to mg, you'll get 250mg (25×10)
so 25 mg is lighter than 25cg(250mg)
so your answer is 25mg is lighter than 25cg.
