Answer:
not number 5 is is biased.
Number 6 is not biased.
Number 7 is not biased.
Step-by-step explanation:
Biased means of an estimator is the difference between this estimator's expected value and the true value of the parameter being estimated.
Answer:
1.42 cm
Step-by-step explanation:
2.5 m = 98.4251 inches
98.4251 in / 11.5 in =8.5587
.5587 inches left over =1.42 cm
Given the following angles:
2x
3x
(x + 12)
(2x + 4)
We know the sum of angle measures 360 degrees.
Thus, we have:
2x + 3x + x + 12 + 2x + 4 = 360
Let's solve for x:
Collect like terms
2x + 3x + x + 2x + 12 + 4 = 360
8x + 16 = 360
Subtract 16 from both sides:
8x + 16 - 16 = 360 - 16
8x = 344
Divide both sides by 8:
Therefore, the value of x is 43
ANSWER:
x = 43
5)
you got it right
2 sides are congruent
6)
2 angles are congruent (each = 45)
8)
the triangle in #8 has been cut off. (is it a right triangle? if so, then there are 2 acute angles)
----------------------------
BTW, # 7 , measure of each angle = 60 (3 congruent angles)

negative exponent - decimal goes to left
positive exponent - decimal goes to right
= 0.000003789
