Let
x------------> number of chickens
y------------> number of pigs

we know that
chicken------> has 2 feet
pig------------> has 4 feet
then
2x+4y=98-------------------->   equation 1
and
x+y=37------------> y=37-x     equation 2

<span>I substitute 2 in 1
</span>2x+4[37-x]=98--------------> 2x+148-4x=98
-2x=98-148-------------> 2x=50-------------> x=25

x+y=37------------> y=37-25-------------> y=12

the answer is
25 number of chickens
12 number of pigs

Answer:

H0 is rejected.There difference in the means for the three assembly methods.

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.

HELP PLZ<br>15 or 16 <br>I am confused
Nuetrik [128]

Answer:

15. It is a function

16. It is a function

Mapping diagram is attached for reference.

Step-by-step explanation:

Mapping diagram is a set of two parallel columns.

The first column includes the 'domain'.

And the second column includes the 'range'.

A relation is a function,

if every domain (x) has only one range (y)

The given coordinates in the set form are in the form (x,y)

15.  We observe that each 'x' is attached to only one 'y'

Therefore this relation is a function.

16. We observe that here also each 'x' is attached to only one 'y'

Therefore this relation is also a function.
