Answer:
Bruno is correct x=1
Step-by-step explanation:
-3(2x+6)+25=1
-6x-18+25=1
-6x+7=1
-6x=-6
1=x
Answer:
5
Step-by-step explanation:
Blue: when x = - 3, y = 5
Green: when x = -3, y = 0
The difference between the two graphs at X = -3 : 5 - 0 = 5
Answer
5
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:
(6, -9)
Step-by-step explanation:
The transformation from point (-3, -3) to point (4, -5) is the same transformation from point (-1, -7) to the missing point.
Let's find the transformation from point (-3, -3) to point (4, -5).
x: 4 - (-3) = 7
y: -5 - (-3) = -2
Now we apply a transformation of 7 in x and -2 in y to (-1, -7).
(-1 + 7, -7 + (-2)) = (6, -9)
Answer: (6, -9)
