Urgent part a full explanation (15 points)

part b : the tides are measured at a fourth location d. the mean of the low tide values at locations a, b , c , and d is -0.54. what is the value of the low tide at location d ? show your work or explain

A - Difference in tides for location C is 6.9 feet and high tide for location A is 8.2 feet.

B - Value of low tide in location D is -0.64 feet.

Step-by-step explanation:

Part A: We are given,

The table showing the difference between high and low tides.

The difference in tides for location C = 7.34 - 0.44 = 6.9

So, the difference in tides for location C is 6.9 feet.

Also, i.e. i.e. i.e. x = 8.2

So, the high tide for location A is 8.2 feet.

Part 2: We are given, the mean of the low tides for the 4 locations is -0.54

Let, 'x' feet be the value of the low ride in location D.

That is,

That is,

That is,

That is,

That is,

That is, x = -0.64 feet

Hence, the value of low tide in location D is -0.64 feet.
