Answer:
YES
Step-by-step explanation:
<span>To find the confidence interval, add and subtract the margin of error from the mean.
With mean 18.7 and margin of error 5.9, you have 95% confidence the answer is between 12.8 and 24.6.</span>
4(5x + 3) - 4x
4*5x = 20x
4 * 3 = 12
20x and 4x are like terms,so 20x - 4x=16x
12 doesn’t have anything to go with,so it just stays
16x + 12 (B is the correct answer)
10 hours seems like the most reliable answer because it matches up the best
Answer:
y=35
Step-by-step explanation:
10(y+7)=12y
10y+70=12y
70=12y-10y
70=2y
70/2=y
35=y
therefore, y=35
