Since she wrote the numbers 1-100, we know that the probability for one number is 1/100.
If she selects a number without looking, it's a 1/100 chance she'll pull out one specific number.
However, here we need to find the probability of a number below 5. There are four numbers below 5 from the range to 1-100 and they are 1, 2, 3, and 4.
Therefore, since there are 4 numbers below 5, we have a 4/100 chance of Jane pulling out a number below 5.
In simplified terms it would be
In decimal form, it would be 0.04
Answer:
8.2
Step-by-step explanation:
We have been given that the ratio of hydrogen to oxygen atoms in water molecules is 2 to 1.
We can represent this information as:
Let x be amount of moles of hydrogen atoms in water beaker. The proportion of hydrogen and oxygen moles will be same in water beaker.
Upon substituting our values in above proportion we will get,
Therefore, the moles of hydrogen atoms in water beaker will be 8.2.
Answer:
Suppose the two like terms are 2 x and 3 x.So to Represent them with algebra tiles ,
Here shape of tiles = Either Square or rectangle
For example , 2 x=Draw two tiles of same color mark variable x in front of it.For, different values of x, we get different number of total tiles.
3 x= Draw three tiles of same color and mark variable x in front of it.For, different values of x, we get different number of total tiles.
For , Polynomial, 3 x -3,
Draw three tiles representing same color, Mark x over it, and then put negative sign in front of it, and draw three tiles of any other color.
To represent Zero,
We can write it as, x -x or p-p
Draw two tiles of same color , and mark negative sign in between .
General formula: A x - A x
Draw A tiles of same color, twice.And mark negative sign in between.
