Answer:
Twice the length of the radius
Step-by-step explanation:
A radius by definition is half of the diameter which means the diameter is twice the radius.
Answer:
let A (2, 6) be (x1, y1)
B (-5, 2) be (x2, y2)
distance AB =√[(x2 - x1)² + (y2 - y1)²]
√[(-7)²+ (-4)²]
√65
Answer:
you will get more money if he gives you 1 cent per day then doubles it
Step-by-step explanation:
if your brother gives you 25 cents per day, at the end of 10 days you will have $2.50
if he gives you 1 cent per day then doubles it, this will be your daily earnings:
day 1- 0.01
day 2- 0.02
day 3- 0.04
day 4- 0.08
day 5- 0.16
day 6- 0.32
day 7- 0.64
day 8- 1.28
day 9- 2.56
day 10- 5.12
then when you add all of this up, you would recieve 10.23 cents at the end of day 10
Answer:
The answer is 0.123.
Step-by-step explanation:
You want to find the intersection between P(Spade) and P(Red). Knowing that there's no replacement, the probability will be given by the formula:
⇒ P(Spade∩Red) = P(Spade)*P(Red/Spade)
⇒ P(Spade∩Red) = P(Red)*P(Spade/Red)
Either formula works, but I'm going to choose to work with the first formula.
Therefore:
P(Spade) = 
P(Red/Spade) = 
So:
P(Spade∩Red) = *
= 
=
