The following is an example of a biased sample of students from a middle school.

1 answer:

5 0

This answer entirely depends on what is being sampled. Is it whether choir is superior to other classes or not? Most likely very biased. Is it about favorite range to sing at? Maybe a little bit biased. Is it something that has nothing to do with choir? Then most definitely not biased.

Again, it entirely depends on what is being asked. One cannot base just "bias opinion" on "20 students in choir" without knowing what the question being asked is.

The graph of the function f(x)=3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20)

<h3>What are exponential functions?</h3>

When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function.

here usual form is specified below. They are written in several such equivalent forms.

The equation of the function is given as:

$f(x)=3(2)^x -4$

Set x = 0, 1, 2 and 3

$f(0)=3(2)^0 -4 = -1\\f(1) = 3(2)^1 - 4 = 2\\f(2) = 3(2)^2- 4 = 8\\\\f(3) = 3(2)^3 - 4 = 20$

This means that the graph of the function f(x) = 3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20).

a survey was done and a company found that 492 out of 500 batteries were good if 6000 batteries were produced how many would be

Tems11 [23]

This is a ratio based question.

$\frac{492}{500} = \frac{x}{6000}$
$x = 6000 \times \frac{492}{500}$
