Range is output for given input
domain is D={-3,0,5}
input -3,0 and 5 for x
f(-3)=(-3)^2-6(-3)+4
f(-3)=9+18+4
f(-3)=31
F(0)=(0)^2-6(0)+4
f(0)=0-0+4
f(0)=4
f(5)=(5)^2-6(5)+4
f(5)=25-30+4
f(5)=-1
Domain={-3,0,5}
Range={31,4,-1}
Answer:
But the graph paper is not here...
The area covered by corn is x
The area covered by wheat is (x+480)
After 80% of wheat was collected, the new area was:
20/10(x+480)
=1/5(x+480)
After 25% of the corn was collected, the new area was:
75/100x
=3/4x
New area equation will be:
(3/4)x=1/5(x+480)+300
(3/4x)=(1/5)x+96+300
solving for x we get:
11/20x=396
x=720
thus the original area of corn was 720 acres
Original area of wheat was 720+480=1200 acres
Answer:
Step-by-step explanation:
Required
Find n, x, p and q
n always represent the population surveyed;
So:
x represents the sample from the population
So:
p always represents the given proportion
Solving for q
