Answer:
circle = 5, triangle = 2, square = 6
Step-by-step explanation:
If we look at the first and second equations, we see that circle + triangle + square = 13. Because triangle + square = 8, we can substitute this into the first equation, therefore, circle + 8 = 13 and circle = 5. Next, looking at the third equation, we see that circle + triangle = 7 and since circle = 5 we know that 5 + triangle = 7, therefore, triangle = 2. Finally, we can substitute triangle = 2 into the second equation which gives us 2 + square = 8, therefore, square = 6.
Answer:
its sampling distribution is centered exactly at the parameter it estimates.
Step-by-step explanation:
An unbiased estimator is an estimator that shows the correct statistic applied for the parameter of the population
Here correct represents that it should not be overestimated or underestimated. In the case when there is an underestimate or overestimate this means that there is a bias
So as per the given options the above option is correct
The perimeter of each figure is 58
The sentence that explains how the bonding pattern in metals makes them good conductors of electricity is <u>A. They are willing </u>to give up their valence electrons.
<h3>What are valence electrons?</h3>
Valence electrons are the electrons in the outermost shell, or energy level, of an atom, which participate in the formation of a chemical bond when the outer shell is open.
<h3>Answer Options:</h3>
A. They are willing to give up their valence electrons.
B. Their nucleus has more protons than neutrons.
C. They are malleable.
D. They have a simpler electron arrangement.
Thus, the sentence that explains how the bonding pattern in metals makes them good conductors of electricity is <u>Option</u> A.

Answer:
132
Step-by-step explanation:
f(1) = 9
f(n) = -4f(n-1) + 4
Let n = 2
f(2) = -4f(2-1) + 4 = -4 f(1) +4 = -4(9) +4 = -36+4 = -32
Let n = 3
f(3) = -4f(2-1) + 4 =-4f(2)+4 = -4 (-32) +4 = 128+4=132
