Answer:
If you written this in standard form you would get 41x-18y=9
Step-by-step explanation:
Answer:
The sample of farms required should be 550 large.
Step-by-step explanation:
Let the sample =K,
mean=np=100
Standard deviation==500
probability =Z=0.90
from the normal probability formula,
Z=
0.9=
500 X 0.9=K-100
450=K-100
K=450+100=550
Hence, the sample of farms required should be 550 large.
Angle A=36 degrees
angle B=54 degrees
36+54=90
D, because 3 and 9 go into some odd numbers. 2 is your answer
1.44 is more than 1.438 so the second brother
