Answer:
d. .00012 or 0.00012
Step-by-step explanation:
The variance of the population proportion formula is given as:
p(1 - p)/n
Where n = sample size
p = population proportion or p(hat)
n = 2000 people
p = 0.52
Variance of the population proportion = 0.52(1 - 0.52)/ 2000
= 0.52 × 0.48 /2000
= 0.2496 /2000
= 0.0001248
Therefore the Variance of the population proportion is approximately = 0.00012

See explanation
Step-by-step explanation:
Let a,b, and c be real numbers.
The distributive property says that:
Assuming we want to simplify:
We apply the distributive property to get:
We can now use rules of exponents to simplify further:
Answer:
<u>The best prediction will be B) 35 </u>
Step-by-step explanation:
By looking at the scatterplot ,
<em>we can see that it the City MPG vs Highway MPG approximately falls on a straight line.</em>
we can either find the slope of it ( which might be a little out of syllabus ) or <em>we can extend the line connecting the maximum number of points.</em>
When we do so, We get a line as attached in the diagram.
And we extend it.
<em><u>From the graph attached we find that the value of City MPG falls somewhere in between the lines of 30 and 35</u></em><u> (</u><em><u> </u></em><u>though this is just and approximation).</u>
thus the more appropriate answer would be : 35
C is the answers f. F f f fr f f. G g
Answer:
the exact would be 3.75 but the rounding would be 4 or 3.5
