Answer 1

Answer:

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, $x+(-1.08)=7.12$ i.e. $x-1.08=7.12$ i.e. $x=7.12+1.08$ 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, $-0.54=\frac{-1.08-0.88+0.44+x}{4}$

That is, $-0.54=\frac{-1.52+x}{4}$

That is, $-0.54\times 4=-1.52+x$

That is, $-2.16=-1.52+x$

That is, $x=-1.52+2.16$

That is, x = -0.64 feet

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