15.3 * 20.8 / 31.2

= 318.24 / 31.2

= 10.2

Answer: when q = 15.3 , p = 10.2

to demonstrate probabilities, a mathematics teacher had students draw marbles from a bag which contained 6 yellow marbles and 10
Feliz [49]
4Okay, so here's how you will do the problem.

first lets find out how many marbles there are in total. At first, there are 16 marbles. (6 yellow + 10 blue)

knowing this
P(Yellow) = 6/16. that simplifies to 3/8
P(Blue) = 10/16. that simplifies to 5/8

We can tell these are correct because when added together the probabilities equal 1 (meaning there's no missing probabilities)

Now, 2 yellow marbles and 3 blue marbles are removed.

this means there are now 4 yellow marbles and 7 blue marbles. this brings the total amount of outcomes is 11.

Now
P(yellow) = 4/11
P(blue = 7/11

we can cross multiply or find out the decimal values and compare to find out if the two are equal

3/8.× 4/11
33........32

5/8 × 7/11
55....56

We will come back to what this shows us in a moment

yellow - .375 (3/8) > .36 repeated
blue - .625 (5/8) < .63 repeated

Both methods show that the probability CHANGED. So, YES the probabilities were affected.

in method one, the cross multiplying show that yellow probability goes down and blue probability goes up. Using the decimals shows the same

hope this helps!

Explain what the slope and intercept mean in the situation.
Vera_Pavlovna [14]

Answer:  The slope is the cost per muffin and the intercept of 3 is the delivery charge.

Step-by-step explanation:

I will assume that the graph has total cost in dollars for the y axis and number of muffins on the x axis.  A slope of 2 means that y will increase by 2 for every 1 increase in x.  That means that the price of a single muffin is $2.

The intercept of 3 at x = 0, means that there is an upfront (delivery) charge of $3.  One muffin would cost $2 for the muffin plus $3 for the delivery, for a total of $5.

10 muffins would cost $20 for the muffins plus $3 for the delivery, for a total of $23.
