Hey! I’m pretty sure it’s B) 8
Answer:
Our fourth number is 52.
Step-by-step explanation:
Let our first even number be <em>x</em>.
Then the second even number must be (<em>x</em> + 2), the third (<em>x</em> + 4), fourth (<em>x</em> + 6), and the fifth (<em>x </em>+ 8).
They sum to 250. Hence:

Solve for <em>x</em>. Combine like terms:

Subtract 20 from both sides:

And divide both sides by five. Hence:

Thus, our sequence is 46, 48, 50, 52, and 54.
Hence, our fourth number is 52.
Answer:
The probability that exactly 12 buyers would prefer green
=0.00555
Step-by-step explanation:
We are given that
p=50%=50/100=0.50
n=14
We have to find the probability that exactly 12 buyers would prefer green.
q=1-p
q=1-0.50=0.50
Using binomial distribution formula








Hence, the probability that exactly 12 buyers would prefer green
=0.00555
The chances are 3/6 or 1/2
