765° = 45°
1485° = 45°
We get 2sin(45°) + tan(45°) + cot(135)
sin(45) = sqrt(2)/2
tan(45) = 1
cot(135) = -1
we get
2*[sqrt(2)/2)] + (1) + (-1)
= sqrt(2)
Answer:
395, 17.212
(360.576,429.424)
Step-by-step explanation:
Given that a procedure yields a binomial distribution with n trials and the probability of success for one trial is p.
Here
Since np and nq are greater than 5 by rule of thumb we can approximate binomial to normal.
Mean = np = 395
Variance = npq =
Std dev = 17.212
Thus X no of successes is N(395, 17.212)
THe the minimum usual value mu minus 2 sigma and the maximum usual value mu plus 2 sigma would be
Answer:
1/3

Let's consider that 23.5 is 100% of rainfall.
23.5 ..... 100 %
21.2 ..... x %
Calculate x:
, which is around 90.2%.
The percent of decrease is 100 - 90.2 = 9.8 %.
Answer: 40%
Step-by-step explanation: 100 boxes, 40 are shaded = 40/100=.4=40%
