y = 4x−10 ; slope m = 4
Parallel has same slope so slope of new line = 4
y = 4x + b
b = y - 4x
Passes through (1, 13)
b = 13 - 4(1)
b = 13 - 4
b = 9
Equation
y = 4x + 9
312
___
1000
Since it reads 0 and 312 thousandths, you would simply place 1000 as the denominator. if it reads hundredths, put 100 as the denominator. if it reads tenths, put 10 as the denominator.
4+2+8+6 = 20 total
8 purple
so 8/20 reduced to 2/5 chance for a purple
then there will be 19 left
6 blue =
6/19 probability of having a blue one
2/5 * 6/16 = 12/80 reduces to 3/20 probability total
Answer:
Part #1: 13/15
Part #2: 11/45
Part #3: 23/45
Step-by-step explanation:
Part #1: So add the total amount of coins: 4 + 7 + 12 + 22 = 45
Since the only coins that are at most $1 are: The $1 coins, 50 cent coins, and the 20 cent coins. That is a total of 7 + 12 + 20 = 39
39/45
13/15
Answer: 13/15
Part #2: Since the only coins that are $1 or $2: The $1 coins and the $2 coins. That is a total of 4 + 7 = 11
11/45
Answer: 11/45
Part #3: Since the only coins that are at least 50 cents: The $1 coins and the $2 coins and the 50 cent coins. That is a total of 4 + 7 + 12 = 23
23/45
Answer: 23/45
