Explain how you could mentally find 8 x 45 by using the distributive property

dangina [55]

First, break up 45 into 40 and 5 then multipy 8(40) which equals 320 and multipy 8(5) which equals 40. Thrn add 320+40 to get the product 360.
Hope this helped

8x45
8(40)+8(5)
320+40
360

9. Courtney rolled a number cube 76 times. The number two appeared 24

gulaghasi [49]

Answer:

$\frac{6}{19}$

Step-by-step explanation:

Experimental probability is based on what has happened already.

Theoretical probability is what should happen.

Example, a coin has 2 sides:

head or tail

The theoretical probability of flipping a head in a flip is:

1/2

But say, an experiment had a coin flipped 10 times and it came 6 heads and 4 tails, the probability of head would then be:

6/10 = 3/5

A bit different than the theoretical one because it is the experimental probability.

Now, back to our question -----

76 times rolled (76 trials total)

2 appeared "24" times (24)

<u>P(rolling a two) = 24/76 = 6/19</u>

THis is the experimental probability of the experiment of 76 trials.
