Henry had $1.05 in nickels and dimes. He had a total of 13

How do you do this?<br> Please help, I’ve been staring at this for like 10 min :)

Answer & Step-by-step explanation:

The formula is given in the middle. You are supposed to insert the value of x into this formula to find the value of y (like in the first given example):

$x=-2\\y=2(-2)+5\\y=-4+5\\y=1$

------

$x=-1\\y=2(-1)+5\\y=-2+5\\y=3$

------

$x=0\\y=2(0)+5\\y=0+5\\y=5$

------

$x=1\\y=2(1)+5\\y=2+5\\y=7$

------

$x=2\\y=2(2)+5\\y=4+5\\y=9$

A bag contains 4 blue marbles, 2 yellow marbles, and 6 orange marbles. What is the probability of picking an orange marble and t

ikadub [295]

We will see that the probability of picking two orange marbles without replacement is 0.23

<h3>How to get the probability?</h3>

If we assume that all the marbles have the same probability of being randomly picked, then the probability of getting an orange marble is given by the quotient between the number of orange marbles and the total number of marbles, this gives:

P = 6/12 = 1/2

And then we need to get another orange marble, without replacing the one we picked before, this time there are 5 orange marbles and 11 in total, so the probability is:

Q = 5/11

Finally, the joint probability (of these two events happening) is the product of the probabilities, so we get:

P*Q = (1/2)*(5/11) = 0.23
