Answer:

The probability that there is no matching pair is 4/7 = 0.5714286.

Step-by-step explanation:

For the first glove we have no restrictions. For the second glove, we have 6 gloves that works for us and 1 that doesnt work (the one that matches the first glove), hence we have 6 possibilities out of 7. Once we pick a good second glove, for the last glove, we only have 4 cases that doesnt match the other two pairs, out of 6 total. This means that the probability that there is no matching pair is 6/7*4/6 = 4/7.

Answer:

A:(-2,-3)

B:(-4.009,1.018) And (-2,-3)

C:x≈0,1.61878812

Step-by-step explanation:

I found the equations

g(x)=e^x+1

p(x)=5/2x+2

f(x)=-2x-7

plugged it in on a graph found the answer to find g(x) all you need to do is know the parent function y=e^2(exponential) and I found where the lines intersect for part A and B and or p(x)=g(x) I did e^x+1=(5/2)x+2

You and your friend were taking turns rolling a die when you thought of a game: If a one is rolled by either player, you pay you
Mazyrski [523]

Answer:

6 times

Step-by-step explanation:

1. There was no cents left

2. If you roll one and get 50 cents you have to minus it with rolling other number than 'one' 5 times because you'll get 10 minus if you roll another number (50 divided by 10 is 5)

3. If you divid 30 (The rolls) by 5 (amount of roll you have to roll if you get one)

4. It equals 6 and 6 is a even number

5. Sorry this was too confusing
