Answer:
Step-by-step explanation:
The given notation is not clear enough, but I will asume that the question is: "Wich is the vector lenght of the vector in a 3 dimensional euclidean space"
Vector lenght of a vector is given by the next formula:
║║=
In this case we have a=2, b=3 and c=1. We should substitute these values in the formula given before to obtain:
║║=
Wich is the answer to the problem.
Answer:
<u>Alternative hypothesis 1</u>: the mean amperage at which the fuses burn out is > 40 amperes.
<u>Alternative hypothesis 2</u>: the mean amperage at which the fuses burn out is < 40 amperes.
Step-by-step explanation:
Recall that the null hypothesis is the fact you want to refute and is in doubt.
So, in this specific case, <em>the null hypothesis would be that the mean amperage at which the fuses burn out is 40 amperes.
</em>
The alternative hypothesis are those that want to refute the null hypothesis, in this case there are 2:
<u>Alternative hypothesis 1:</u> the mean amperage at which the fuses burn out is > 40 amperes.
<u>Alternative hypothesis 2:</u> the mean amperage at which the fuses burn out is < 40 amperes.

Answer:
576
Step-by-step explanation:
PEMDAS
113*5=565
565+8=573
573-8=565
565+11=576
I think the answer is 119
