Find the mixed number equivalent to the im<br> proper fraction 22/6
Naddik [55]

Answer:

3\frac{2}{3}

Step-by-step explanation:

Given the following question:

\frac{22}{6}

In order to convert a mixed number into an improper fraction we have to divide the numerator (in this case; 22) by the denominator (in this case; 6) to find your answer.

\frac{22}{6}
\frac{22}{6} \div2=\frac{11}{3}
\frac{11}{3}=11\div3=3\frac{2}{3}
=3\frac{2}{3}

Let three represent how many times 3 goes into 11, let 2 represent the remainder while of course keeping the denominator the same. Your answer is "3 2/3."

Hope this helps.

Step-by-step explanation:

Calculating gives the following results.

ANOVA Table

Source        DF                  Sum                Mean            F Statistic      

                                       of Square         Square

Treatments       2               4560               2280             9.865

(between groups)

 

<u>Error            27                  6240                231.111                                   </u>

Total         29                   10,800  

Error SS= SST -SSTR = -10,800-4560=6240    

d.f for SSTr = r-1= 3-1

D.f for SST= n-r= 30-3= 27

Total D.f= d.f for SSTr+D.f for SST= 27+29

MSTR= SSTR/d.f= 4560/2= 2280

MSError= Error SS/ d.f= 6240/27=231.111

F test= MSTR/ MsError= 2280/231.11= 9.865

The P- value < 0.01 which  is less than 0.05 therefore H0 is rejected.

There is sufficient evidence to reject H0.

Rearrange h=d/3+2 to make d the subject
yarga [219]

Answer:

d = 3(h - 2)

Step-by-step explanation:

h = d/3 + 2

taking 2 to the right hand side

h - 2 = d/3

multiplying both sides by 3

3(h - 2) = d

therefore

d = 3(h - 2)
