The answer is y=2/5x+7.
Hope that helps! :D

Here, I wore it down and took a picture of it.
Reminder: the formula for a geom. seq. is
a(n) = a(1)*r^(n-1), where a(1) is the first term, n is the counter and r is the common ratio.
I first noted that 243 is a power of 3; specifically, 243=3^5, or 243=3(3)^4, or 243=(3^2)(3)^(4-1). Notice that I'm trying here to rewrite 243=3^5 in the form a(n) = a(1)*r^(n-1): a(4) = a(1)(3)^(4-1), or a(4) = a(1)(3)^3 = 243. Then by division we find that a(1) = 243/27 = 9. Is it possible that a(1)=9?
Let's try out our formula a(n)=9(3)^(n-1). Steal n=9 and see whether this formula gives u s 59049:
n(9) = 59049 = 9(3)^(9-1), or 9(3)^8. True or false? 3^8= 6561, and 9(3)^8 = 59049.
YES! That's correct.
Therefore, the desired formula is
a(n) = 9(3)^(n-1). The first term, a(1) is 9(3)^(1-1) = 9(3)^0 = 9*1 = 9.
It would be B. because if you put the numbers on a number line, you notice that -14 is further down than -3 since -3 is closer to 0, so -14 is less than -3
Answer: b. (0.561, 0.794).
Step-by-step explanation:
We know that the confidence interval for population proportion (p) is given by:-
, where 
= Sample proportion.
n = Sample size.
z* = Critical z-value.
Let p = proportion of horses with enteroliths who are fed at least two flakes of alfalfa per day.
As per given , n = 62
z-value for 95% confidence = z*=1.96
A 95% confidence interval is given by:
Thus , the required 95% confidence interval is (0.561, 0.794).
Hence, the correct option is b. (0.561, 0.794)..
