Answer:
Step-by-step explanation:
Rewrite this expression as (27^(1/3) )². this is equivalent to:
( ∛27 )² or (∛27)(∛27).
If you wish to evaluate this expression, it is ( 3 )( 3 ) = 9.
Answer: 12 inches
Explanation:
12 inches = 1 feet
Answer:
a) 
b) The should sample at least 293 small claims.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so , which means that the answer of question a is z = 1.645.
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
(b) If the group wants their estimate to have a maximum error of $12, how many small claims should they sample?
They should sample at least n small claims, in which n is found when
. So
The should sample at least 293 small claims.
Answer:
The area of the whole field is 54400yd^2
Step-by-step explanation:
says that I add 10 yards in each zone, that means that 10 yards is added twice at 1000 yards
1000yd + 2*10yd = 1020yd
we have to know that one yard equals 3 feet
so to have the length in feet we only multiply it by 3
1020 * 3 = 3060ft
Now that we know the length and width of the court, we can calculate the area by multiplying them
a = b * h
a = 3060ft * 160ft
a = 489600 ft^2
the result is in square feet
if we want it in square yards we just have to divide 2 times by 3
489600/(3*3) = 54400yd^2
