Answer:
V = 60 m3
Step-by-step explanation:
Volume of a square pyramid:
V = (1/3)a2h
Slant Height of a square pyramid:
By the pythagorean theorem we know that
s2 = r2 + h2
since r = a/2
s2 = (1/4)a2 + h2, and
s = √(h2 + (1/4)a2)
This is also the height of a triangle side
Answer:
-12 47/60
Step-by-step explanation:
-(1 1/5) + (-8 3/4 -2 5/6) = -(1 + 8 + 2 + 1/5 + 3/4 + 5/6)
= -(11 + 12/60 +45/60 +50/60) . . . 60 is the LCD of 1/5, 3/4, 5/6
= -(11 + 107/60) . . . . . . . . . . . . . . . . add the fractions
= -(12 47/60) = -12 47/60 . . . . . . . write as a mixed number
___
Your graphing calculator may be able to do this for you. Many handle mixed numbers with ease.
Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The population proportion is 
The sample size is n = 343
Generally given that the ample size is large enough , i.e n > 30 then the mean of this sampling distribution is mathematically represent

Generally the standard deviation is mathematically represented as

=>
=> 
Generally the the probability that the sample proportion will differ from the population proportion by less than 4% is mathematically represented as



=> 
From the z table the area under the normal curve to the left corresponding to 1.887 and - 1.887 is

and

So

=> 
Answer:
Step-by-step explanation:
The cost = x * (1 + 0.075) = x * 1.075 = 1.075*x
(3/25)(179/25)(7.72)(7.723) and if you add a zero at the end of 7.72 you get 7.720 and if you compare it to 7.723 you can see that it's less than 7.723 Hope it helps :D
