Question

What is the mean height of the low tides for the four days, considering the heights as follows: 20.22 ft, 2.64 ft, 20.22 ft, and 2.64 ft?

a) 20.22 ft

b) 2.64 ft

c) 11.04 ft

d) -0.22 ft

Answer 1

To find the mean height of the low tides for the four days, add up the heights and divide by the number of days.

Step-by-step explanation:

To find the mean height of the low tides for the four days, you need to add up all the heights and then divide by the number of days. In this case, the heights are 20.22 ft, 2.64 ft, 20.22 ft, and 2.64 ft. Adding the heights together, you get 20.22 + 2.64 + 20.22 + 2.64 = 45.72 ft. Since there are four days, divide the total height by 4: 45.72 / 4 = 11.43 ft.

Therefore, the mean height of the low tides for the four days is 11.43 ft.
