Answer:
C. Elizabeth wants to estimate the mean vacation days of coworkers at her company. She collects data by selecting a random group of coworkers within her department.
Step-by-step explanation:
Sampling Bias is case, in which some section of population have higher or lower chance of being selected in sample than others.
'Elizabeth wants to estimate the mean vacation days of coworkers at her company. She collects data by selecting a random group of coworkers within her department'. This case is of Convenience Sampling, where person selects sample only as per his/ her convenience.
Elizabeth has conveniently chosen sample workers from her department, so they have higher chance of being in sample, others have lesser chance. Hence, this is Sampling Bias

Answer:
50
Step-by-step explanation:
lxb=144
16xb=144
b=9
perimeter=2(l+b)
=2(16+9)
=50 cm
Sure. The function is a parabola. Because the coefficient of the x^2 term is positive, it opens upward. that means that it vertex is a minimum point.
You can verify that the vertex is (0,24). That means that at the point x=0, the height of the bridge is 24m. So if the level water rises below 24 m, the bridge is safe to use.
Answer:
180
Step-by-step explanation:
in Geometry if you want a farewell you need to know the parallel lines they never touch they're always the same distance apart it's as if they don't like each other much and there's only one thing that comes between the line that passes right through each of them called the transversal line it has several angle properties just like these: vertically opposite angles are equal corresponding angles are equal alternate interior angles are equal co-interior angles equal 180* vertically opposite angles are equal corresponding angles are equal alternate interior angles are equal co-interior angles equal 180*
