Expected value E(x) = 0.6(200,000) + 0.2(100,000) - 0.2(200,000) = 120,000 + 20,000 - 40,000 = 100,000
Therefore, the expected value is $100,000, so the company should build the mousetrap.
18 + 22 + 23 + 24 + 25 + 26 + 30= 168
168/7= 24
the missing number is 24
Good Luck! XD
Answer:
W = 58 yards, L = 210 yards
Step-by-step explanation:
P = 2 (L + W)
L = 4w - 22
P = 2 (4W - 22 + W)
536 = 8W - 44 + 2W
536 = 10W - 44
10 W = 536 + 44
10W = 580
W = 58 yards
Since L = 4W - 22
L = 4 (58) - 22
L = 232 - 22
L = 210 yards

3p^2q^3r^2√r
Step-by-step explanation:
3√p^4q^6r^5
= 3p^2q^3r^2√r
Hope that helps
Solve for the area of the circular region first:
A = pi*r^2
A = pi*(30 mi)^2
A = 2827.43 mi^2
Density = 70000 people/2827.43 mi^2
Density = 24.76 = 25 people/mi^2 <--ANSWER Plz vote brainnliest
