Answer:
Study of the collection, organization, analysis, interpretation, and presentation of data
Step-by-step explanation:
In a cyclic quadrilateral, the opposite angles add up to 180 degrees.
Opposite angle to angle A = Angle D.
A + D = 180
64 + D = 180
D = 180 - 64
D = 116°
Option E.
Answer:
3.96mm/year
Step-by-step explanation:
Given that :
Given that:
Observed variation in water level over 6.2 years = - 13.64mm
Average annual trend shows rise in water level at 1.8 mm / year
difference between how much average water levels rose and how much the water level fell in the part of the river she observed?
Average Yearly observed variation :
Observed variation / number of years
-13.64mm / 6.2 years
= - 2.16 mm
Hence, observed yearly fall = - 2.16 mm
Yearly rise = 1.8mm / year
Difference :
( 1.8 mm/year) - (-2.16mm / year)
= (1.8 + 2.16) mm/year
= 3.96 mm/year
The event that either M1 or M2 fails has probability

by the addition rule. Failure events are independent, so

so that

Denote this probability by
. Then
follows a geometric distribution with this parameter
and has density

The expectation is
.
Answer:
0.1 is rational as it can be written as 
Step-by-step explanation:
Rational decimals can be expressed as a fraction using integers, and 0.1 =
, so it is rational.
