Gill rolls a number cube 78 times. How many times can he expect to roll an odd number greater than 1?
bekas [8.4K]
Im assuming its just a regular number cube with 6 numbers 
there are only 2 odd numbers above 1 ( 3 and 5) 

so the ratio is 2/6 

you want to know how manny times (x) will you roll those numbers out of 78 roll 
the ratio is x/78 

multiply 

(2/6) = (x/78) 

cross multply to give you 6x= 156 and divide by 6 

<span>to give you x = 26

Sauron [17]
You can use pythagorean theorem. 3 miles would be one leg and 2 miles would be the other. (We’ll just call these two a and b in the formula. Letter c, also known as your hypotenuse, will be this ‘straight line distance’.) In order to find this you’ll use: a^2 + b^2 = c^2
Then you’ll find the square root of your sum to get the answer.

Answer: 3^2 + 2^2 = ?

Name: _
Paraphin [41]

Answer:

0.6, 2/3, 73%

Step-by-step explanation:

To convert 2/3 into a decimal, do 2 divided by 3 which would equal about 0.67.

If you want to convert a percent into a decimal, take the decimal place and move in over to the left 2 digits.

<u>Example:</u>

73.0% (I added the ".0" to show the decimal)

Move decimal to the left twice.

So, it would be 0.73.
