Nine-thousand four-hundred thirty-two
Answer:
The third side is sqrt(77)
Step-by-step explanation:
Since this is a right triangle we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
2^2 + b^2 = 9^2
4+ b^2 = 81
Subtract 4 from each side
b^2 = 81-4
b^2=77
Take the square root of each side
sqrt(b^2) = sqrt(77)
b = sqrt(77)
The third side is sqrt(77)
Answer: (0.665 , 0.777)
Step-by-step explanation:
Given : Sample size of consumers: n=420 ;
Number of consumers say their ColorSmart-5000 television sets did not need a repair=303
The the sample proportion for consumers say their ColorSmart-5000 television sets did not need a repair : 
Significance level : 
Critical value = 
The confidence interval for population proportion is given by :_

i.e. 

Hence, a 99 percent confidence interval for the proportion of all ColorSmart-5000 television sets that have lasted at least five years without needing a single repair = (0.665 , 0.777)
30 and 30 because 27 is 30 round up 32 is 30 round down.
A2 + b2 = c2
7^2 + 5^2 = c2
49 + 25 = c2
74 = c2
square root of 74 = c2
8.602325267 = c
The length of the hypotenuse is around 8.6 cm.
