For this case we define the following variable:
<em>x: unknown number
</em>
We then have the following equation:

From here, we clear the value of x.
We have then:

Answer:
An irrational number that can be multiplied by negative square root of 41 to get a product that equals 1 is:

Answer:
The other side =
units
Step-by-step explanation:
A right triangle has a side of length
units and;
the hypotenuse is 
According to Pythagorean theorem,
a² + b² = c² , where a and b are the two legs of a triangle and c is the hypotenuse.
Lets say a² =
and c² = (
b² = c² - a²
b² =
-
= 
So b =
=
units.
So the other side =
units.

Answer:
The correct option is B) 0.0228
Step-by-step explanation:
Consider the provided information.
The manager of a grocery store has taken a random sample of 100 customers. The average length of time it took the customers in the sample to check out was 3.1 minutes. The population standard deviation is known to be 0.5 minute.
Thus, the value of n = 100,
and σ = 0.5
We want to test to determine whether or not the mean waiting time of all customers is significantly more than 3 minutes.
The null and alternative hypotheses are,
and
Compute the test statistic 



By using the table.
P value = P(Z>2) = 0.0228
Hence, the correct option is B) 0.0228
