Please have a look at diagram attached.
We can use Pythagorean theorem to find lenght of each wire.
x^2 = 16^2 + 12^2
x^2 = 256 + 144
x^2 = 400
x = 20
Lenght of one wire is 20
Hence lenght of two wires would be 20 * 2 = 40 feet : Answer
Hope it will help you :)
Answer:
b
Step-by-step explanation:
We must determine the the x value at 90% confidence interval. We find this from a table relating confidence intervals and x values. For 90%, z is 1.645.
WE must determine the mean of 19 and 23:
We must determine the standard deviation. We let n be the number of population which is 2. We need to take the numbers 19 and 23 and subtract each by the mean and square the answer:
We then determine the mean of these two values as:
Now we take the square root of 365:
The standard deviation is 19.1
The answer is b
C hope this helps you out
Answer:
x^87
Step-by-step explanation:
Multiplying x^22 and x^7 results in x^29.
Then we have:
(x^29)^3 = x^87
Recall that (a^b)^c = a^(bc) and that a^b*a^c = a^(b + c)
