Answer:
The estimate for the proportion of Americans over 33 who smoke is 0.28.
Step-by-step explanation:
Proportion of Americans over 33 who smoke.
Number who smoke divided by the size of the sample.
In this question:
Sample of 1267.
913 don't smoke, so 1267 - 913 = 354 smoke. Then
The estimate for the proportion of Americans over 33 who smoke is 0.28.
Answer:
plug in -3 where any x is in the equation. I reccomend doing it in parenthesis just so things work out nicely
Step-by-step explanation:
<u>c) 3, 6, 9 12</u> is NOT a geometric progression
<h3>Further explanation </h3>Geometry sequences are series of numbers that have a constant ratio
or can be interpreted:
Each number is obtained by multiplying the previous number by a constant
The sequence can be:
a, ar, ar², ar³, ... etc.
Can be formulated
where:
a is the first term, and
r is the common ratio
So we have to see the series has the same ratio or not
a.
