Answer:
The expected frequency for people against the project and who have over 120 feet of property foot frontage is 3.9.
Step-by-step explanation:
The data provided is:
Opinion
Front Footage For Undecided Against Total
Under 45 feet 12 4 4 20
45-120 feet 35 5 30 70
Over 120 feet 3 2 5 10
Total 50 11 39 100
The formula to compute the expected frequency is:
Compute the expected frequency for people against the project and who have over 120 feet of property foot frontage as follows:
Thus, the expected frequency for people against the project and who have over 120 feet of property foot frontage is 3.9.
The domain is all real numbers, reason being, you can put any number for x and get a valid coordinate.
Answer:
f(1)=-3
f(-4)=-11
f(6)=0
Step-by-step explanation:
Use the correct formula depending on what (x) equals.
When (x=1) you use the second formula because 1 is greater than -2 but less than 4
When (x=-4) you use the first formula because -4 is less than -2
When (x=6) you use the third formula because 6 is greater than 4
2x+30y=12x+17
30y=10x+17
y=(10/30)x+(17/30)
x-intercept:
0=(10/30)x+(17/30)
-17/30=(10/30)x
-17/10=x

______________________________________________________
<h2>Explanation:</h2>
To find the area of the shaded region, we must find the area of the inner white triangle and subtract it from the area of the outer blue one.
Outer:
A = 
bh
A = (12 · 5)
A = (60)
A = 30 mm²
Inner:
A = bh
A = (4 · 3)
A = (12)
A = 6
30 - 6 = 24
