How do you do this problem?

Answers

Answer 1

Answer: The pythagorean theorem states that a² + b² = c².
We have a = 10 and c = 20.
100 + b² = 400
Subtract 100 from each side.
b² = 300
Get the square root of 300.
It could be expressed as b ≈ 17.321, or could stay in radical form as $√(300)$ .
Hope this helps!

Jennifer it's two pennies 105 times how many times can expect both going to come up heads

Answers

Jennifer has two pennies. She flips both pennies 105 times each. How many times can she expect both pennies to come up heads simultaneously?

Assuming I have correctly interpreted your question,
The probability both coins come up heads is $(1)/(2) * (1)/(2) = (1)/(4)$
Thus the expected number of simultaneous heads is 105/4 or 26.25
