Let's start with part B. if it was originally 10 cm tall and it goes up 0.5 cm. each day, then we know that to go up one cm it needs two days. With that information we can say that 8*2 = 16. So it needs 17 days to go up 8.5 cm which would make it 18.5 cm tall.
To find the diameter of a circle, using only the circumference, you need to divide the circumference by π, or 3.14.
So in this case, you must divide 12 by 3.14, which gives you 3.82.
I even double checked this, and should be correct then.

Answer:
c. 0.75
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
We have the following sample space
That is, the possible outcomes.
I am going to call boys b and girls g
b - b - b
b - b - g
b - g - b
b - g - g
g - b - b
g - b - g
g - g - b
g - g - g
Total outcomes:
8 outcomes
What is the probability that they will have at least one boy and at least one girl?
Desired outcomes:
At least one boy and at least one girl
b - b - g
b - g - b
b - g - g
g - b - b
g - b - g
g - g - b
Six desired outcomes.
Probability

The correct answer is:
c. 0.75
