All the members of a construction crew work at the same pace. six of them working together are able to pour foundation in 22 hours. how many hours would this job take if the number of workers decreased by factor of 2, increased by 2, and increased by 4?

I am sorry but I do not know the answer

Step-by-step explanation:

I want to know the answer though I've been stuck on this question for the past 3 days!

Step-by-step explanation:

for the first one the answer is 44

to figure out the equation we need to this first 6-4 we get the 4 by 2×2 the product of 2×2 so back to 6-4 we do that and get 2 know from here we divide 6÷2 and get 3 which is a big role in all of the problems next we make the equation. 22×3÷6 or 3/6=44

for the next problem the answer is 11

for this problem you don't really need to do anything but adjust the equation from the previous problem all you need to do is simplfy the 3/6 which is 1/2 or 1÷2 so now we make the equation

22×1÷2=11

I'm so sorry but my computer won't let me type in the solution for the next problem but hope this helps!   :)

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
