A political candidate has asked you to conduct a poll to determine what percentage of people support him. If the candidate only wants a 0.2% margin of error at a 99.5% confidence level, what size of sample is
needed? When finding the z-value, round it to four decimal places.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

the answer is a

step-by-step explanation:

i don't see any

step-by-step explanation:

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
