Answer:
9z^8
Step-by-step explanation:
2z^8 + 7z^8
The average number of failures can be found by multiplying .41 (equivalent to 41%) by 375. When you do this, you get 153.75 failures. Rounded to the nearest 10th is 153.8 failures; the nearest whole number, 154 failures.
Answer: 0.6827
Step-by-step explanation:
Given : Mean IQ score : 
Standard deviation : 
We assume that adults have IQ scores that are normally distributed .
Let x be the random variable that represents the IQ score of adults .
z-score : 
For x= 90

For x= 120

By using the standard normal distribution table , we have
The p-value : 

Hence, the probability that a randomly selected adult has an IQ between 90 and 120 =0.6827
X²-8x
factor out x
x(x-8)
y=x(x-8)
We know that
surface area of sphere=4*pi*r²
r=√[surface area/(4*pi)]
for surface area=27648
r=√[27648/(4*3)]-------> r=√2304-----> r=48 units
volume of a sphere=(4/3)*pi*r³-----> (4/3)*3*48³---> 442638 units³
the answer is
