Step-by-step explanation:
Assuming the data is as shown, restaurant X has a mean service time of 180.56, with a standard deviation of 62.6.
The standard error is SE = s/√n = 62.6/√50 = 8.85.
At 95% confidence, the critical value is z = 1.960.
Therefore, the confidence interval is:
180.56 ± 1.960 × 8.85
180.56 ± 17.35
(163, 198)
Restaurant Y has a mean service time of 152.96, with a standard deviation of 49.2.
The standard error is SE = s/√n = 49.2/√50 = 6.96.
At 95% confidence, the critical value is z = 1.960.
Therefore, the confidence interval is:
152.96 ± 1.960 × 6.96
152.96 ± 13.64

Answer:
<h2><u><em>$71,713</em></u></h2>
Explanation:
- Find The Total Cost Of The 355 Chairs
- 355 Chairs - $199 Per Chair
355 · 199 = $70,645
- Club Spent $70,645 And Had $1,068 Remaining
$70,645 + $1,068 = $71,713
<h2><em><u>The Club Had $71,713 At First</u></em></h2>
- PNW
Yd * yd * yd = yd^3
The volume is measured in cubic yards.
D) 34/5 because 6(5) = 30 30+4=34 , so its 34/5
Answer:
Hi there!
Your answer is:
It will take 2.2 months for both gyms to be the same amount of money!
Step-by-step explanation:
Fitness 19:
39+ 17x
Anytime Fitness:
50+ 12x
Put them equal to each other:
39+17x = 50+12x
-12x
39+5x = 50
-39
5x = 11
/5
x= 2.2 months
39+17(2.2)= 76.4$
50+12(2.2)= 76.4$
Hope this helps!
