<h2>
Weight of column is 555.83 N</h2>
Step-by-step explanation:
Size of column = 6 inch x 6 inch x 8 ft
Size of column = 0.5 ft x 0.5 ft x 8 ft
Volume of column = 0.5 x 0.5 x 8 = 2 ft³
Specific weight of concrete = 62.4 lb/ft³
Mass = Volume x Specific weight
Mass = 2 x 62.4
Mass = 124.8 lb = 124.8 x 0.454 = 56.66 kg
Weight = 56.66 x 9.81 = 555.83 N
Weight of column is 555.83 N
Answer:
The expected amount of pap smears that must be inspected before the first abnormal one is found is 50
Step-by-step explanation:
If 2 percent of all pap smears show signs of abnormality, then the probability that a pap smear is abnormal is 0.02.
Let X be the amount of pap smears needed before the first abnormal case is found. X has geometric ditribution with parameter p = 0.02. The mean of X, in other words, the expected amount of cases that must be inspected before the first abnormal one appears, is 1/p = 1/0.02 = 50.
Note tanx = sinx / cosx. What you typed is wrong.
For complementary Angles, that is Angles that add up to 90 degrees.
For example 60 and 30 are complementary. 20 and 70 are also complementary, same is 40 and 50. That is because they both add up to 90.
For Complementary Angles:
sinx = cos(90 - x)
cosx = sin(90 -x)
tanx = cot(90 -x)
cotx = tan(90 -x). cotx = 1/tanx
Therefore tan(90-A) = cotA.
