Answer:
415
Step-by-step explanation:
Confidence Level = 98%
Z-value for this confidence level = z = 2.326
Margin of error = E = 0.08
Mean = u = 6.6
Standard deviation =
Required Sample Size = n = ?
The formula for margin of error is:
Re-arranging the equation for n, and using the given values we get:
Thus, the minimum sample size required to create the specified confidence interval is 415

Why'd you put this in the math section lol? Anyways, hope this helps! :D
Answer:
substitution method would go as follows
5x-2=7x-8 we than rearange it so it becomes 5x-7x=-8-2 this than becomes -2x=-6 so x=3
we can than substitute 3 for x in one of the first equations
y=7 times 3-8 = 21-8 = 13
so therfore the interception should be at 3,13

Step-by-step explanation:
so i cant put an answer for some reason but here it is: when dividing fractions you would need to multiply to solve. The easyist way to do so from the ways i learned is keep change flip. so keep: 2/3 change a divide to a multiplication simbol and flip 1/4 to 4/1 so your left with G: 2/3 x 4/1
hope that helps btw if you need me to explain more let me know whats confusing you so i can help!!
