If you have a new deck of shuffled cards, what is the probability you will choose an ace? (52 cards, no jokers) A) 1 13 B) 1 2 C) 1 4 D) 1 6

Answers

Answer:

B 1/2

Step-by-step explanation:

I looked it up.

But I think it'd be C because there would be 4 aces in the deck, and C has 1/4

Answer: 1/13 is the correct answer.

Step-by-step explanation: You put the total amount of aces, which is four, on the top part of your fraction and the total number of 52 cards on the bottom of your fraction. Since four will divide into both numbers, you simplify 4/52 to get 1/13. 4 divided by four is one. 52 divided by 4 is 13. That is how you get your 1/13 from 4/52. Answer was confirmed correct on the test I took. I hope this helps you! Thanks!

LC)Variable c is 9 more than variable w. Variable c is also 3 less than variable w. Which pair of equations best models the relationship between c and w? (5 points) c = w – 9
c = 4w + 3
c = w + 9
c = w – 3
w = c + 9
w = c – 3
w = c – 9
w = 4c + 3

Answers

c=w+9 and c=w-3

w=c-9 and w=c+3

These pairs of equations are best relationship models between c and w.

How to find pair of best relationship model for c and w?

We have given,

Variable c is 9 more than variable w which can be written as

c=w+9

It can also be written as :w=c-9

It is also given that,Variable c is also 3 less than variable w, which can be written as:

c=w-3

It can also be written as: w=c+3

This way our pair of relationship between c and w are:

c=w+9 and c=w-3

w=c-9 and w=c+3

Variable C is 9 more than variable w.

C = w + 9
w = C - 9

Variable C is 3 less than variable W.
