-375 + -175 = -550
The final depth is 550 ft below sea level, or -550.
To get the distance DC we proceed as follows:
AB-CD
=11-3
=8
BC=15
hence using Pythagorean theorem
c²=a²+b²
c=DC
a=BC
b=8
thus
c²=15²+8²
c²=225+64
c²=289
thus
c=√289
c=17 units
Answer: B. 17 units
the answer in point-slope form is y = 1/4x-2 so your y-intercept is -2 and from there, move up one and right four. your points would be (0, -2) and (4, -1)
hope this helped! :)
49 cm > 4 dm
because 1 dm = 10 cm
Glad I could help, and good luck!

The 95 percent confidence interval for the mean time (in seconds) it takes students to complete this maze is: 39±1.96(8.83/√4).
<h3>Confidence interval</h3>
Using this formula
Confidence interval=Mean ± z × Standard deviation√Sample size
Where:
- xMean=39
- Z value for 95% CI=1.96
- Standard deviation=8.83
- Sample size=4
Let plug in the formula
Confidence interval=39±1.96×8.83/√4
Confidence interval=39±8.65
Inconclusion the 95 percent confidence interval for the mean time (in seconds) it takes students to complete this maze is: 39±1.96(8.83/√4).
