Answer:
Write and solve an equation of ratios:
16 miles 20 min
----------- = -----------
12 miles x
Then 16x = 240, and x = 240/16 = 15.
It will take 15 minutes to travel 12 miles.
The answer is D .............
Answer and explanation:
Null hypothesis: p is not 54%
Alternative hypothesis : p is equal 54%
First find standard deviation
Standard deviation is:
σ = √[ P ( 1 - P ) / n ] = √[ 0.54×0.46/220 ] =0.033
The z score is calculated p-P/σ = (0.54-0.50)/0.033 = 1.2121
Therefore we can conclude that proportions are not same and fail to reject the null hypothesis
<span>ahh okay i was going to say...thats a straight line haha....okay well lets see....what is 4^0? 1 right? what is 4^1? 4 ...4^2? 16 ...4^3? 64....make a graph with those points</span>
Use the distance formula:

Plug in the given coordinates:

Simplify:

You can leave it as:
or in decimal form as: 7.2
