Answer:
Yes, the value 1411.8 cm³ is significantly high.
Step-by-step explanation:
Consider the provided information.
The brain volumes (cm cubed) of 20 brains have a mean of 1111.2 cm cubed and a standard deviation of 125.3 cm cubed.
The range rule of thumb to identify the limits separating values that are significantly low or significantly high is:
The range rule of thumb identifying significant values are as.
Significantly low values are μ-2σ
Substitute the μ = 1111.2 and σ = 125.3 in above formula.
1111.2-2(125.3)=860.6
Significantly high values are μ+2σ
Substitute the μ = 1111.2 and σ = 125.3 in above formula.
1111.2+2(125.3)=1361.8
The value is significantly high due to the value 1411.8 cm³ is not lie between the values 860.6 cm³ and 1361.8 cm³.
Hence, Yes, the value 1411.8 cm³ is significantly high.

Answer:
14.488 amperes
Step-by-step explanation:
The amplitude I of the current is given by
where
= amplitude of the energy source E(t).
Z = Total impedance.
The amplitude of the energy source is 120, the maximum value of E(t)
The total impedance is given by
where
<em>
R= Resistance
</em>
<em>L = Inductance
</em>
<em>C = Capacitance
</em>
<em>w = Angular frequency
</em>
= inductive reactance
= capacitive reactance
As E(t) = 120sin(12t), the angular frequency w=12
So
and
Finally
