The area of a trapezoid = (a + b)/2 x h
Where a and b are the lengths of the parallel sides and h is the perpendicular distance between them.
When (a + b)/2 x 6 = 30
then (a + b)/2 = 5
a + b = 10
Possible values for (a,b) are (4,6) (3,7) (2,8) (1,9) assuming a < b but (7,3) is also valid.
Any positive real value is possible so (4.8, 5.2) and (0.3, 9.7) are valid
In general {a,b both real: 0
Answer:
just add them

Answer:
- 1/65
Step-by-step explanation:
the multiplicative inverse of - 65 is - 1/65
(- 1/65) x (- 65) = 1
Answer:
Go catipiller
Step-by-step explanation:
The standard deviation is 0.4801.
To find the standard deviation we use the formula:
s = √n(p)(1-p), where n is the sample size and p is the probability.
Using this, we have:
s = √600(0.02)(1-0.02) = √600(0.02)(0.98) = 0.4801.
