Answer: 8.94

Step-by-step explanation:

By common logic, you can say that l=8, w=4 and h=2.

The diagonal of the base can be found by using Pythagorean Theorem.

Pythagorean Theorem: a²+b²=c²

Since we know the a and b of the base, we can find c, the diagonal.

a and b is the l and w. We can use the equation to find c.

8²+4²=c²

64+16=c²

80=c²

c=√80

c≈8.94

The diagonal is approximately 8.94

A jar contains 99% fair coins, and 1% double-headed coins. you took a coin at random, then toss it 3 times and observed 3 heads.
slamgirl [31]
1 in 100, because you have 99% fair coins and just 1% double-headed one, then 99 + 1 is obviously 100, so you have a 1 in 100 chance
