Astudy was conducted to determine if there was a difference in the humor content in british and american trade magazine advertisements. in an independent random sample of 270 american trade magazine advertisements, 56 were humorous. an independent random sample of 203 british trade magazines contained 52 humorous ads. does this data provide evidence at the .05 significance level that there is a difference in the proportion of humorous ads in british versus american trade magazines.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
