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.
Answer:
Hello! Your answer here is 10−5.
Step-by-step explanation:
To convert 0.00001 to a power of 10, we use scientific notation<em>. </em>Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form.
In this problem, the given decimal number is 0.00001. We must move the decimal 5 places to the right, which gives us 1.0.
Then, we multiply 1.0 by 10 raised to the negative of the number of places we have moved the decimal point - so we multiply 1.0 by 10−5, which gives us our answer:
10−5
Px - 45 = QX + 75
Px - Qx = 75 + 45 = 120
A. If P = - 45 and Q = - 75, then
- 45x + 75 x = 120
30x = 120 and x = 40
B. If P = 45 and Q = - 15, then
45x - 15x = 120
30x = 120
x = 40
D. If P = 15 and Q = 75, then
15x - 75x = 120
- 60x = 120
x = - 2
C. If P = 15 and Q = 15, then
15x - 15x = 120
0 = 120 which is absurd.
Hence, P = 15 and Q = 15 result in an equation with no solution.
The answer would be the second one, you can immediately cross off the first one and 3rd one, 2 x 200 = 400 - 300 = 100 :)
