The american heart association is about to conduct an anti-smoking campaign and wants to know the fraction of americans over 21 who smoke. step 1 of 2 : suppose a sample of 292 americans over 21 is drawn. of these people, 225 don't smoke. using the data, estimate the proportion of americans over 21 who smoke. enter your answer as a fraction or a decimal number rounded to three decimal places

Step-by-step explanation:

Out of 292 drawn Americans over 21, 225 of them don't smoke. That means the rest of them are smokers:

So there are 292 - 225 = 67 smokers here.

We can then calculate the portion of Americans over 21 who smoke:

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
