How can you use mental math to determine if a ratio is simplified

Mathematics

You can see if it is simplified by checking if the numbers can be divided with the same number. Typically, this is done mentally.
Ex: You can mentally determine that 10:4 is not simplified, because both can be divided by 2.
You can then determine that 5:2 is simplified.

The daily water consumption for an Ohio community is normally distributed with a mean consumption of 722,500 gallons and a stand
Allisa [31]

Answer:

0.0060

Step-by-step explanation:

The z-score is given by

<em>z = (866,475-722,500)/57,429 = 2.51 </em>

The probability is given by the area under the Normal curve N(0,1) to the <em>right</em> of 2.51

In <em>Excel </em> this value is found with the formula

=1-NORMDIST(2.51,0,1,1)

and in <em>OpenOffice Calc </em>

=1-NORMDIST(2.51;0;1;1)

<em> (NORMDIST(2.51;0;1;1) gives the area to the left of 2.51, so 1-NORMDIST(2.51;0;1;1) gives the area to the right of 2.51) </em>

and equals 0.0060

Andrews [41]

Answer:

6003

Step-by-step explanation:

Given : They harvested 5491 apples from one side of the McMillan farm.

             They harvested 512 from the other side of the farm.

To Find : The total number of apples harvested at the McMillan.

Solution :

Since we know that

Number of apples harvested from one side of the McMillan farm = 5491

Number of apples harvested from other side of the McMillan farm = 512

Now we are supposed to calculate the total number of apples

So, we need to sum the number of apples of both the sides .

⇒5491+512

⇒6003

Hence , the number of apples harvested  at the McMillan is 6003
