Rob sent an email survey to 2,000 cell phone owners asking about their satisfaction with their current plan. Only 256 people ret

urned the survey and they were predominately 18-24 years old.
Which of the following statements is true?


Rob is ignoring the assumption that all survey participants will want to act independently.


The survey likely has bias because the people who could not answer differ from those who did answer.


Rob included too many people on the survey list, affecting the data collected.


The survey suffers from census issues because only 256 people responded.

Which statements are true regarding the diagram? Check all that apply.
Zina [12379]

Answer:

2.CE lies on line m.

4.Ray AD is identical to ray AC.

6.Angle ECB is formed by CE and CB.

Step-by-step explanation:

A diagram has been provided.

Our task is to identify the valid statements regarding the diagram.

1.CB is found on line n.

CB does not align with line n since points C and B do not lie on that line.

Thus, this statement is false.

2.CE is situated on line m.

CE is indeed positioned on line m because points C and E are both on this line.

This statement is accurate.

3.Ray BC is equivalent to ray CB.

A ray begins at a single point and continues indefinitely without a terminal point.

Ray CB starts at point C and stretches out from point B.

However, ray BC does not exist.

This statement is therefore false.

4.Ray AD is equivalent to ray AC.

Both AD and AC are rays.

They are equivalent since both originate from point A and extend in the same direction.

5.Angle EAD is formed from AE and DA.

This is false because angle EAD is created by ray AE and ray AD, not by ray DA.

6.Angle ECB is generated by CE and CB.

This is true as angle ECB is made by ray EC and ray BC.

Which of the following functions is graphed below?
Leona [12618]

We have a piecewise function consisting of a parabolic graph and a linear graph.

When the parabolic graph of y=x^2 is elevated by 6 units, the new equation becomes

y=x^2+6.

Given that the parabola aligns with this requirement, its equation can be expressed as

y=x^2+6

The parabola extends to x=3, where there is an open circle at this point. Thus, we need to use a less than sign.

Next, the line's equation is determined as y=-x+6

Since there is a solid dot, we must employ the greater than or equal to sign.

Consequently, the piecewise function's equation is derived as

y=\left\{\begin{matrix}
x^2=6, x

C is the right choice.

A dormitory manager buys 38 bed sheets and 61 towels for $791.50. The manager get another 54 bed sheets and 50 towels for $923 f
lawyer [12517]
Define x as the price for each bed sheet and y as the price for every towel. The linear equations representing the scenario are:
                          38x + 61y = 791.50
                                   54x + 50y = 923
When solving for x and y in the equations, the results are x = 12 and y = 5.5. Consequently, one bedsheet costs $12, and each towel is priced at $5.5.
