Apaper reported that in a representative sample of 287 american teens age 16 to 17, there were 75 who indicated that they had sent a text message while driving. for purposes of this exercise, assume that this sample is a random sample of 16- to 17-year-old americans. do these data provide convincing evidence that more than a quarter of americans age 16 to 17 have sent a text message while driving? test the appropriate hypotheses using a significance level of 0.01. (round your test statistic to two decimal places and your p-value to four decimal places.) z = p-value =

based on context clues you gave i'm assuming the answer would be c.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

c(x)= 6x + 3
