Answer:

I predict he will select the blue marble 8 times

Step-by-step explanation:

In total there are 60 marbles so if they select a marble 30 times, that is half of 30. I just took half of the blue marbles and that would be the theoretical probability

Find the median of 6,2,0,1,1,2,3,2,0,2,3,4,2,3,5
neonofarm [45]
The median is 2
Median = Middle

First, arrange the numbers from lowest -> highest

This would be:
0, 0, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 4, 5, 6

Now, strike off one number from each side (so 0, then 6, then 0, then 5) until you are only left with one or two numbers.

If you are left with one number, that is your median!

If you are left with two numbers, than you add them together, then divide that number by 2 (for example if you were left with 7 and 8, 7+8=15. 15/2=7 1/2)

In this case, you are left with one number, 2, so 2 is your median.
I hope this helped!

[XTRA POINTS] Number 32 looks easy, but i cant get it...
Tju [1.3M]

Diameter = 6, so length of diagonal = 6

a² + b² = c²

a = x, b = x, and c = 6

x² + x² = 6²

2x² = 36

x² = 18

x = √18

x ≈ 4.2426

x ≈   4.2 in.


Hope this helps you!

Have an amazing day :)

Mrs.Wicker bought a case of 24 juice boxes for $12.How much did each box of juice cost?
NeTakaya
Hey there!

To find the answer, we can divide the total cost by the total number of juice boxes.

\frac{12}{24}

= \frac{1}{2}

A half of a dollar is 50 cents.

Thus, each juice box cost 50 cents.

Have an awesome day! :)
