Answer:
1/10
Step-by-step explanation:
There are 6 marbles in the bag. 3 out of 6 are green.
3/6 = 1/2
So, he has a 1/2 of picking a green marble.
After getting a green marble, Joe doesn’t replace it meaning there are now only 5 marbles in the bag.
Since there’s one red marble in the bag the chance of trying one is 1/5.
Now to find the chance or drawing a green and red marble you need to do the equation:
1/2 x 1/5
This equals 1/10.
The probability is 1/10
Answer:
12.30 x 6 = 73.8
Step-by-step explanation:
Hello,
I would be happy to help.
For Part A, you just count the number of terms, there are 3. So, it is a trinomial.
For Part B, you look at the highest exponent value, it is 2. So it is a second degree polynomial.
For Part C, you have to sub in the values for each year. You are looking for the number of years since 1930, so subtract 1930 from each year.
2020 - 1930 = 90
2030 - 1930 = 100
Then, sub in those values into the given expression to find the density.
0.005(90)^2 - 0.127(90) + 1 = 30.07
0.005(100)^2 - 0.127(100) + 1 = 38.3
Remember to use the order of operations!
Good luck,

You take the discount first. Alex is completely right. Laura is if and only if that 110% is really just 10%. So I'll use Alex's method because it is for certain correct.
28.5*35/100 = 9.975 (which is the amount of the discount)
28.5 - 9.975 = 18.525 (which is the amount paid with the discount factored in.)
Now you take 10% of this amount and add it on which gives 18.525 * 10/100=1.825 which is the amount of the tax.
Add this on to the selling price 18.525 + 1.825 = 20.3775 and now is the time to do your rounding.
The cash register will ring up 20.38 which is just under $21.00
Answer: $20.38
