The equation of the graph shown plotted in the coordinate plane is y = x + 4. What statement is not true about this graph? A. Ea

frez [133]

Definately option C

As it's mentioned y=x+4 it must be function
So in function every domain has its unique range.
Hence here the slope is not constant

The graph shown is a parabola which is not y=x+4

So option C is wrong

A theater group surveyed 146 audience members after a show and found that 132 of them wanted to see the show again. Find the sta

Sophie [7]

Answer:

0.024

Step-by-step explanation:

Sample size (n) = 146 people

The proportion (p) of people who answered that they would be interested in seeing the show again is:

$p=\frac{132}{146}\\ p=0.9041$

The standard error for a sample of size 'n' and proportion 'p' is:

$SE = \sqrt{\frac{p*(1-p)}{n}}\\SE = \sqrt{\frac{0.9041*(1-0.9041)}{146}}\\ SE=0.024$

The standard error for the sample proportion of audience members who want to see the show again is 0.024.
