1 in 4
4 suits, each with the same number of cards. 1/4 of the cards are diamonds, so theres a 1 in 4 chance of drawing one.
If leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)
if leg b is unknown, then. b = √(c² - a²)
for hypotenuse c missing, the formula is. c = √(a² + b²)
51. I checked the comments but I still didn't understand it, sorry :/
54.
(43+45+47+49)=184
They are all odd and they are in consecutive order (one after another)
can u add the table so its easier
Answer:
Step-by-step explanation:
<u>Given</u>
<u>Simplify</u>
Compare left and right sides and
<u>Find b:</u>
- <u />
b = 15 ⇒ b = 15*3/5 = 9
<u>Find c:</u>
- 1 + c = 7 ⇒ c = 7 - 1 = 6
<u>Find a:</u>
- a + 2 = 10 ⇒ a = 10 - 2 = 8
<u>Find d:</u>
<u>Solution is:</u>
