Answer:
D (4.34,3.22)
Step-by-step explanation:
Line Y (2,4), (-4,6)
**y=mx+b slope-intercept form
m=slope; b=y-intercept
plug in 1 point
Line Z (8,8) (-5,9)
Substitution
Answer:
q = 4.
Step-by-step explanation:
4(q + 1) = 20 Divide both sides by 4:
q + 1 = 5 Subtract 1 from both sides:
q = 4.
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
Area of a square is side length^2
Area = 15^ 2 = 15 x 15 = 225 square inches.
100<28+12d
If she wants to collect over 100 then the 100 would be less than (<) what she collects. She is starting with 28 so whatever she collects is added on. Because she collects 12 a day, you would multiply 12 by however many days, d, she collects.
