Tom runs at a constant speed and travels 11 meters in 4 seconds. If Tom runs for 8 seconds at this constant speed,

how far will he travel?

He will travel 22 meters.

Step-by-step explanation:

This question can be solved by a simple rule of three.

11 meters in 4 seconds.

How many meters is 8 seconds?

4 seconds - 11 meters

8 seconds - x meters

He will travel 22 meters.

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
