Umm I'm not sure on this but a regular probability is 1/9 so maybe taking out the 3 would leave 6/9 or in other word 2/3
Answer:
Step-by-step explanation:
the position of the boat on the waters surface = 0 (zero)
Carmen and Jen's swimming depth. = -15
Kelly invested $1,500 in the stock market on January 1
She lost 1/3 of it by the end of January or that is:
(1/3)*1500 = $500
the remaining amount is 1500 - 500 = $1,000
she lost 2/5 of the remaining amount by the end of February:
(2/5)1000 = $400
what is left is: 1000 - 400 = $600.
Answer:
Point estimate is 16 and Margin of error is 9
Step-by-step explanation:
The point estimate is given by the following formula:
Point estimate = (Lower Bound + Upper Bound) / 2
Replacing we have:
Point estimate = (7 + 25) / 2 = 32/2
Point estimate = 16
Now, the margin of error is given by the following equation:
Margin of error = (Upper Bound - Lower Bound) / 2
Margin of error = (25 -7) / 2 = 18/2
Margin of error = 9
