2 and 9
6 and 9
would be have the least common multiple of 18
Answer:
The answer is 6.403
Step-by-step explanation:
Using the pythagorean theorem, a^2+b^2=c^2, we can plug 4 units into a, and 5 units into b. Plugging these into the formula results in 4^2 + 5^2 = c^2. Simplifying, we get 16 + 25 = c^2. Simplifying even more, we get 41 = c^2. Using a calculator to get the square root of both sides results in c = 6.40312424.
Answer:
x = 27
y = 45
Step-by-step explanation:
No she is not correct, because the absolute value of a number is its distance from zero on a number line. Therefore, you would take a number, say -1. The absolute value of this number is 1. So, add 1 and you would get 2. If I'm correct, 2 is not equal to zero. I hope this helps you out! ;)
Answer:
a. 4/52
b. 1/2
c. 1/4
d. 10/13
Step-by-step explanation:
In order to obtain the probabilities, you have to apply the formula:

Where P(A) is the probability of an event A, n(A) is the number of favorable outcomes for the event and n is the total number of possible outcomes.
<u>For part a:</u>
The total number of 4 cards is 4, because there are four suits and a card 4 for each suit
n(a)= 4
n=52 (The total number of cards)
P(a)=4/52
<u>For part b:</u>
There are two suits with black cards and 13 cards in each suit. Therefore, the number of black cards is: 13(2)=26
n(b)=26
n=52
P(b)=26/52=1/2
<u>For part c:</u>
The total number of cards with diamonds is 13
n(c)=13
n=52
P(c)=13/52=1/4
<u>For part d:</u>
There are 3 face cards in each suit, therefore the total number of face cards is (3)(4)=12. The rest of the cards are none-face cards, therefore:
n(d)= 52-12 = 40
n=52
P(d)=40/52=10/13
