n high school?" Of the 1,500 readers who responded, 65% said no. What does this show?
A. No meaningful conclusion is possible without knowing something more about the characteristics of her readers.
B. The survey would have been more meaningful if Tia had picked a random sample of the readers who responded.
C. The survey is meaningless because of voluntary response bias.
D. The survey would have been more meaningful if Tia had used a control group. E.This was a legitimate sample, drawn randomly from her readers, and is of adequate size to allow the conclusion that most of Tia's readers who are college-bound high school students would not have taken more college prep courses.

Answer:

C) The survey is meaningless because of voluntary response bias.

Step-by-step explanation:

Voluntary response bias happens when the people that are surveyed volunteer themselves to answer the questions. Only people with a strong opinion, either in favor or against, tend to offer themselves as voluntary subjects.

This same problem happens when radio or TV hosts decide to solicit their audience participation, only people with strong feelings will participate since it is optional. People that are relatively indifferent to the subject will not participate in the survey. This is why most voluntary surveys tend to lean towards extreme answers.

A basketball shot is taken from a horizontal distance of 5m from the hoop. The height of the ball can be modelled by the relatio
olasank [31]
This is the concept of application of quadratic expressions. Given that the height of the ball is modeled by the equation;
h=-7.3t^2+8.25t+2.1+5
The time taken for the ball to hit the ground will be given as falls;
-7.3t^2+8.25t+7.1=0
to solve for t we use the quadratic formula;
t=[-b+/-sqrt(b^2-4ac)]/(2a)
a=-7.3, b=8.25, c=2.1
t=[-8.25+/-sqrt[8.25^2+4*7.3*7.1]/(-2*7.3)
t= -0.572
or
t=1.702
since there is not negative time we take the time taken for the ball to hit the ground will be: t=1.702 sec

Two cars leave from a town at the same time traveling in opposite directions. One travels 5 mph faster than the other. In 3 hour
Doss [256]

Let the slower cars speed equal X.

The faster cars speed would be X+5 ( 5 mph faster).


They traveled for 3 hours

Multiply the time of travel by speed to equal the number of miles traveled.

So you have:

3X + 3(X+5) = 267 miles

Simplify the left side:

3X + 3X+15 = 267

Combine like terms:

6x + 15 = 267

Subtract 15 from each side"

6x = 252

Divide each side by 6:

x = 252 / 6

X = 42


The slower car was traveling at 42 mph and the faster car was traveling at 47 mph.
