Can someone please write out the decimal 112.001 as a fraction? And it would really really help me a lot if you could explain ho
iragen [17]

So let's leave the 112 aside for now. The question then becomes how to write the decimal 0.001 as a fraction. The key is to remember that

0.x  corresponds to "tenths" so x/10

0.0x corresponds to "hundredths" --> x/100

0.00x corresponds to "thousandths" --> x/1000

The number 0.001 is just 1 thousandth, or 1/1000

Now back to 112.001. You can write it as

112/1 + 1/1000 =

(112,000+1)/1000 =

112,001/1000  (the fraction you were looking for)

Leokris [45]

Answer:

d. 2 in the numerator, 15 in the denominator

Step-by-step explanation:

Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".  

The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"  

If we assume that we have 3 groups and on each group from j=1,\dots,n_j we have n_j individuals on each group we can define the following formulas of variation:  

SS_{total}=\sum_{j=1}^p \sum_{i=1}^{n_j} (x_{ij}-\bar x)^2  

SS_{between}=SS_{model}=\sum_{j=1}^p n_j (\bar x_{j}-\bar x)^2  

SS_{within}=SS_{error}=\sum_{j=1}^p \sum_{i=1}^{n_j} (x_{ij}-\bar x_j)^2  

We want to test this hypothesis:

\mu_{Master card}=\mu_{Visa}=\mu_{Discover}

And we have this property  

SST=SS_{between}+SS_{within}  

The degrees of freedom for the numerator on this case is given by df_{num}=df_{within}=k-1=3-1=2 where k =3 represent the number of groups.

The degrees of freedom for the denominator on this case is given by df_{den}=df_{between}=N-K=18-3=15.

And the total degrees of freedom would be df=N-1=18 -1 =17

On this case the correct answer would be 2 for the numerator and 15 for the denominator.  

d. 2 in the numerator, 15 in the denominator
