Answer:
C
A parallelogram has 2 sets of parallel lines, but this has only one.
650 -136=514
514 divided by 25 = 20.56
So it would be 21
This will give you a little extra chairs but they have to be equal in each row
7:48 pm when converted into regular time.
Answer:
The estimate of 100- year annual rainfall amount is 274.5cm
Step-by-step explanation:
From the question, x (mean) =152 ; Sx ( standard deviation) = 30, T (time) 100 years, P (period) = 1/T = 1/100 =0.01
The frequency factor is expressed as:
where w= for zero is less than P less than or equal to 0.5
w=
= 3.034
= 2.326
=2.18
=1.477
∴
=
=274.5cm
Answer:
15 m
Step-by-step explanation:
The area of the circle is
A =pi r^2
A = pi 4^2 = 16 pi
The area of the sector is 30
The fraction is
30/16 pi
Take this time 2pi which are the radians of a circle
30 /16 pi * 2 pi = 15/4
This is the number of radians the angle is
The arc length is s = r * theta where theta is in radians
s = r theta
= 4 * 15/4
= 15
