What’s the square root of -121

Mathematics
1 answer:
irakobra [83]2 years ago
5 0
The answer is 11 i

<em />
<em>Explanation:
</em>
The square root needs to be a number that can be multiplied by itself and equal the original number.

In this case, the number is 11, 11*11 = 121

However, you are looking for the square root of a negative number, due to this you would add i to the answer,
i = imaginary number, or -

( Depending on your grade/ teacher however, you can put "no solution"

Incomes in a certain town are strongly right-skewed with mean $36,000 and standard deviation $7000. a random sample of 75 househ
Svet_ta [14]
Since the sample is greater than 10, we can approximate this binomial problem with a normal distribution.

First, calculate the z-score:

z = (x - μ) / σ = (37000 - 36000) / 7000 = 0.143

The probability P(x > 37000$) = 1 - P(<span>x < 37000$), 
therefore we need to look up at a normal distribution table in order to find 
P(z < 0.143) = 0.55567 
And 
</span>P(x > 37000$) = 1 - <span>0.55567 = 0.44433

Hence, there is a 44.4% probability that </span><span>the sample mean is greater than $37,000.</span>
