Answer:
Solution given:
length = (3x+5)
breadth = (2y+4)
we have
area of rectangle: length* breadth
=(3x+5)(2y+4)
opening bracket
=3x(2y+4)+5(2y+4)
=6xy+12x+10y+20
=<u>12x+10y+6xy+20</u><u>u</u><u>n</u><u>i</u><u>t</u><u> </u><u>square</u>
D(1,-5,-4,-7) R(0,7,-7,-4) Domain are your x values and range is your y values
3 tens= 30
7 tenths= 0.7
8 hundredths= 0.08
so 30+ 0.7+0.08= 30.78
Answer:
We are given:

is the critical value at 0.02 significance level
is the margin of error
Therefore, the required sample size is:




Therefore, the required sample size n = 1061
