Distribute -5.5(2-6x) first
-5.5 x 2 = -11 & -5.5 x -6x =33x
=> 33x - 11
33x - 11 -2.5x
subtract common like terms
33x - 2.5x = 30.5x
Answer: 30.5x -11
Answer:
I would say yes, reset the machine, because the sample mean of 124.9 ounces is out of the 95% confidence interval
Step-by-step explanation:
It depends on your alpha level of test.
Would you be fine if the 124.9 ounces is in a 95% confidence interval?
we know u = 125 ounces, σ = 0.30 ounces
sample mean E = 124.9 ounces n = 40
Our test statistic is Z = [(E - u) / σ ]* which follows a Standard Normal
so...
Check if P ( -1.96 < Z < 1.96) = 95% so
Z = [(E - u) / σ ]* = [ (124.9 - 125)/ 0.3 ] *
Z = (-0.1/0.3)* 6.3245 = -2.1 ... this is out of the 95% confidence interval
I would say yes, reset the machine, because the sample mean is out of the 95% confidence interval
A technique of expressing an equation in the most efficient form possible while altering the quality of the underlying statement is known an algebraic equation.
<h3>Simplifying the given expression:</h3>
⇒ (- 20 - 3i) - (- 22 - 1i)
⇒ (- 20 - 3i + 22 + 1i)
⇒ (2 - 2i)
Therefore the simplification of the given expression is "(2 - 2i)"

Answer:
Step-by-step explanation:
The answer is 11.
x - 30 = 14 - 3x
4x = 44
x = 11
A number (x) decreased by 30 (x - 30) is the same as (=) 14 decreased by 3 times the number (14 - 3x).
It is equal to 357 i added it and thats the answer
