The value of x that completes the conditional relative frequency table by column is 0.85
<h3>How to determine the value of x?</h3>
From the complete question, we have the following column elements
0.15 x 1
Express a sum
0.15 + x = 1
Subtract 0.15 from both sides
x = 0.85
Hence, the value of x that completes the conditional relative frequency table by column is 0.85

in the first half he would have swam 1 km. there are 1000m in a km so 1000/200=5 so he swam the first 200 fly, then a 200 breast, then a 200 fly again, then another 200 breast the finish the first 1 km with a 200 fly. so we switched strokes 4 times.
PS i wouldn't recommend doing a 2 km swim fly and breast
Answer: 20 calls
Explanation: This is because since 40 is half of 20, you would need to divide by 2 to get 10. If you convert the division to multiplication, 10 * 2 = 20. So, the answer would be 20 calls.
