The option is the 3rd bubble
Answer:
10-52.85ft squared 11-144.84centimeters squared 12-304meters squared
Step-by-step explanation:
A-bh/2 10-7*15.1=105.7/2=52.85ft squared
A-bh 11-10.2*14.2=144.84cenitmeters squared
A-bh 20*15.2=304meters squared
Answer:
lol idk
Step-by-step explanation:
look it up
Step-by-step explanation:
Confidence interval = mean ± margin of error
CI = μ ± ME
The mean is μ = 8.7.
Margin of error = critical value × standard error
ME = CV × SE
At 95% confidence and 9 degrees of freedom, CV = 2.262.
SE = s / √n
SE = 3.3 / √10
SE = 1.04
The margin of error is:
ME = 2.262 × 1.04
ME = 2.36
CI = 8.7 ± 2.36
CI = (6.34, 11.06)
The 35% is 81.90 plus the 234. So your answer would be $315.90 is the original price. If you need me to explain it let me know :)
