Answer:
Step-by-step explanation:
The experimental probability is based on what already happened.
So we see that both of them found a total of 11 + 3 + 36 + 40 + 134 = 224 coins.
The coins that are worth MORE THAN 10 cents are 11 quarters and 3 fifty-cent pieces (we exclude dimes because we want MORE THAN 10 cents, NOT 10 cents exactly).
So 11 + 3 = 14 coins are worth MORE THAN 10.
So the probability of finding one worth more than 10 cents next is 14/224 = 1/16
Answer:
x=7/5 or 1.4
Step-by-step explanation:
5x+17=24
you would subtract 17 from both sides.
5x=7
Then you would divide 5 from both sides
x=7/5 or 1.4
-30x - 20: We can see that both numbers have a factor of -10, because 30 and 20 are multiples of 10 and -30x and -20 are both negative. So the factored form is -10(3x + 2).
12x - 28: The greatest common divisor of the two numbers is 4, so the factored form is 4(3x - 7).
-10x - 5: Like the first problem, the biggest factor is -5, so the factored form is -5(2x + 1).
