Answer:
Step-by-step explanation:
Provided PNWL is a parallelogram
PW = 2PM = 2(9) = 18
m∠PNW = m∠WLP = 144°
PL = NW = 12
m∠NPL = 180 - 144 = 36°
Answer:
2.6
Step-by-step explanation:
Given :
x 1 2 3 4
P(x) 0.3 0.2 ? 0.4
Σp(x) = 1
Hence, 0.3 + 0.2 +? + 0.4 = 1
0.9 +? = 1
? = 1 - 0.9
? = 0.1
For the mean :
E(X) = ΣX*P(X)
(1 * 0.3) + (2 * 0.2) + (3 *0.1) + (4* 0.4)
0.3 + 0.4 + 0.3 + 1.6 = 2.6
Hence, the mean = 2.6
Answer:
7
Step-by-step explanation:
37 People / 6 is 6.18 Rounded up is 7
