Answer: 208.
Step-by-step explanation:
The formula to find the minimum sample size is given by :-
(1)
, where z* = critical z-value (two tailed).
= Standard deviation ( from prior study ) and E = Margin of error.
As per given , we have
Margin of error : E= 0.29
Confidence level = 85%
Significance level =
Using z-table , the critical value (two -tailed)=
As per previous study , Variance =
Now, the required minimum sample size = [Substitute the values in formula (1)]
[ Round to the next integer]
Hence, the minimum number of third graders that must be included in a sample = 208.
to be a parallelogram its front sides must be equal to each other
so, we equalize the length of two sides that are face to face
and solve for w
the value of w must be 10

The Volume formula of a Cylinder is
V =
r²h
(r = radius, h = height)
The radius given is 8 and the height is 4, We can plug in the known values
V =(8)²(4)
=256
= 256 units³ (You can leave the answer in this form)
≈ 804.2 units³ (approximately)
Units³ because it is a volume (3D shape)
