Rita recorded the number of cyclists on a saturday for 4 weeks. the results for the first 3 weeks are shown in the table.
the average (mean) number of cyclists on a saturday is 43. complete the table with the missing number at week 4.
week 1. 38
week 2. 42
week 3. 39
week 4. -

The number of cyclists on week 4 is 53.

Step-by-step explanation:

The mean is calculated by dividing the sum of numbers by how many number there are. In this case we have 4 weeks. The mean is 43, meaning in total, Rita had recorded

172 cyclists.

Now we can subtract the number of cyclists recorded on every other week, leaving the answer to the question.

Rita recorded 53 cyclists on week 4.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
