ale4655 [162]
Its just a matter of subbing in ur answer choices to see which ones are correct...but remember, for it to be a solution, it has to satisfy BOTH equations.

(-1/4,-4)
y = 8x - 2
-4 = 8(-1/4) - 2
-4 = - 8/4 - 2
-4 = -2-2
-4 = -4 (correct)

(-1/4,-4)
y = -4x - 5
-4 = -4(-1/4) - 5
-4 = 1 - 4
-4 = -4 (correct)

Therefore, ur solution is (-1/4,-4)

Using the Formula n=1/(ME)2 to Determine Sample Size When we want confidence and use the conservative estimate of , we can use t
PIT_PIT [208]

Answer:

The sample size needed is 40000.

Step-by-step explanation:

The sample size needed is:

n = \frac{1}{M^{2}}

Use this formula to determine the sample size needed for a margin of error of 0.005

This is n when M = 0.005. So

n = \frac{1}{M^{2}}

n = \frac{1}{0.005^{2}}

n = 40000

The sample size needed is 40000.
