Answer:

12\frac{1}{2}

Step-by-step explanation:

25/2 =  12 1/2

Numerator. This is the number above the fraction line. For 25/2, the numerator is 25.

Denominator. This is the number below the fraction line. For 25/2, the denominator is 2.

Improper fraction. This is a fraction where the numerator is greater than the denominator.

Mixed number. This is a way of expressing an improper fraction by simplifying it to whole units and a smaller overall fraction. It's an integer (whole number) and a proper fraction.

Step 1: Find the whole number

We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.

25/2= 12.5 = 12

Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.

Step 2: Get the new numerator

To work this out we'll use the whole number we calculated in step one (12) and multiply it by the original denominator (2). The result of that multiplication is then subtracted from the original numerator:

25 - (2 x 12) = 1

Step 3: Our mixed fraction

We've now simplified 25/2 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:

12 1/2

In this case, our fraction (1/2) can be simplified down further. In order to do that, we need to calculate the GCF (greatest common factor) of those two numbers. You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 1 and 2 is 1.

We can now divide both the new numerator and the denominator by 1 to simplify this fraction down to its lowest terms.

1/1 = 1

2/1 = 2

When we put that together, we can see that our complete answer is:

12 1/2

The fill weight of a certain brand of adult cereal is normally distributed with a mean of 920 grams and a standard deviation of
gulaghasi [49]

Answer:

The probability that it will weigh more than 904 grams = 0.9452

Step-by-step explanation:

Given -

Mean (\nu ) = 920 grams

Standard deviation (\sigma  ) =10

Let X be the weight of a certain brand of adult cereal

if we select one box of cereal at random from this population

The probability that it will weigh more than 904 grams =

P(X> 304) = P(\frac{X - \nu }{\sigma }> \frac{904 - 920}{10})

                   = P(Z> -1.6)    Putting ( Z = \frac{X - \nu }{\sigma } )

                   = 1- P(Z<  -1.6)  Using Z table

                   = 1 - .0548

                   = 0.9452

2/3x=−1/3x−4<br><br> (they are not being divided)
Mashutka [201]
2/3(x)-(-1/3(x)-4)=?
?=0

1÷3 = 0.3

2/3(x) - 0 -1/3(x) = ?
? = 0

2 ÷ 3 =.67

4(3)/ 3

your "x" becomes a negative

So, (-x) - 12 / 3 - 2/3(x)
we get the "12" from multiplying 4(3) from each other

Your like term of this problem▶ -x + 12

2(x) - (-x) - 12 / 3

3(x) + 12

x + 4 = 0
-4 -4
---- ----
4x - 4

4x - 4 = 0

We have one solution to this equation

So, therefore your answer for this question is:
x = -4
