Answer:
x =12
Step-by-step explanation:
we have:
-2(4-x)-5=11
apply distributive property:
-2*4 +2*x -5=11
we have:
-8 +2x -5 =11
2x -13 =11
2x = 11+13
2x= 24
x = 24/2
finally we have the x value:
x =12

Biased estimators are Sample median & sample standard deviation
Unbiased are sample mean sample variance and sample proportion

Answer: 2.865
Step-by-step explanation:
For the general quadratic equation ax^2 + bx + c = 0 the discriminant is b^2 - 4ac.
So, for x^2 + x + 2 = 0, a = 1, b = 1, and c = 2, therefore
b^2 - 4ac = 1^2 - 4(1)(2) = 1 - 8 = - 7.
Answer: - 7
