Answer:
14
Explanation:
For independent variables X and Y;
S.D(X - Y) is expanded as :
S.D(X) + S.D(Y)
If S.D(X) = 6 and S.D(Y) = 8 ; where, X and Y are independent ;
SD(X-Y) = SD(X) + SD(Y)
SD(X - Y) = 6 + 8
SD(X - Y) = 14
Answer:
-2 and -12
Explanation:
A dilation is a transformation of a geometric image that is known to change its size not it shape.
The size of the figure basically depends on the scale factor (k).
When k >1 then there would be expansion.
When k <1 then there would be contraction.
When k=1 then no change in size
I.e for conraction the scale factor (k) must be negative
from the given options, the scale factor produce a contraction under a dilation of the original image would be -2 and -12
<h3 /><h3>Hence the correct answers are:-2 and -12 </h3>

Answer:
Answer might be A
Explanation:
I don't know the full passage but from what you wrote about the "Red Grouper, it might be a figurative language.
The energy in the capacitor at the instant after the switch is closed, based on the potential across the capacitor is 31 mJ
<h3>What is the energy amount in the capacitor?</h3>
Because total energy is constant, this can be found by the formula:
= Initial energy in capacitor - Energy in inductor
The initial energy in the capacitor is:
= 0.5 x 4 x 10⁻⁶ x 200²
= 0.08J
The energy in the inductor is:
= 0.5 x 0.2 x 0.7²
= 0.049
The energy in the capacitor at that instant is:
= 0.08 - 0.049
=0.031 j
= 31 J
