Number six is 4x4 there because 4x4= 16
Hey there!
When multiplying variables with the same degree, be sure to add the two degrees being multiplied.
For example;
x * x; both of these terms have the degree of "1" as they are "x^1". Since we are multiplying them, we need to add their degrees.
x^1 * x^1 = x^2
Now that we've broken down what we are doing, let's apply this new knowledge to your problem.
(x^3)(x^-2); Remember to just add the degrees; -2 + 3 = 1
This means our product is x^1, or just x.
I hope this helps!
Answer:
All real numbers except x = 2, x = 5
Step-by-step explanation:
If the denominator is equal to 0 then the function would be undefined.
Set the denominator equal to 0.
x² - 7x + 10 = 0
Factor the left side of the equation.
(x - 5)(x - 2) = 0
Set the factors equal to 0.
x - 5 = 0
x = 5
x - 2 = 0
x = 2
The domain is all real numbers except x = 2 and x = 5.
Answer:
B and D
Step-by-step explanation:
A is false as it would be 3.08 when rounded.
C is false as it is rounded to the tenth not hundredth.
Answer:
The probability that a randomly selected monthly cell phone bill is less than $95 is 0.9772
Step-by-step explanation:
The average monthly household cellular phone bill is $73.

Local monthly household cell phone bills are normally distributed with a standard deviation of $11.

We are supposed to find the probability that a randomly selected monthly cell phone bill is less than $95 i.e.P(x<95)


Z=2
Refer the z table for p value
So,p value = 0.9772
Hence the probability that a randomly selected monthly cell phone bill is less than $95 is 0.9772
