Answer:
Option B) The battery storage capacity is significantly different than 60 Ah, at a confidence level of 95 %
Step-by-step explanation:
We are given the following in the question:
Mean storage capacity = 60 ampere-hour
95% confidence interval =
Thus, the correct answer based on the confidence interval is
Option B) The battery storage capacity is significantly different than 60 Ah, at a confidence level of 95 %
Since it is a two sided test we test whether the mean storage capacity is 60 Ah or different than 60 Ah
Thus, the battery storage is different from 60 Ah because the mean storage capacity does not lie in the 95% confidence interval.
Answer:
(88a+80)(8a+8)
88a(8a+8)+80(8a+8)
704a²+704a+640a+640
704a²+1344a+640
(40y+zy)(4y+zy)
40y(4y+zy)+zy(4y+zy)
160y²+40zy²+4zy²+z²y²
160y²+44zy²+z²y²

Hi BellaMath1717,
Your Question:
Bob spent $37.80, including tax, on a pair of jeans. How much did the jeans cost if there was 8% sales tax?
Solution:
Step 1: Find The Tax
8% = 0.08
37.8 x 0.08 = 3.024
Tax = $3.024
Step 2: Find The Total
37.80 + 3.024 = $40.824 = $40.82
Final Answer:
$40.82
The answer is X=3
Hope this helps!
