a² + b² = c²
c² = 19² + 34²
c² = 1517
c = √1517
c = 38.95 units.
Find missing angle A:
Find Missing B:
Answer: Missing length = 38.95 units ; Missing angles = 29.2° and 60.8°
Answer:
-472x+ 177
Step-by-step explanation:
-(8x-3)59
-59(8x-3)
-59*8x-(-59)*3
-59*8x+59*3
Answer:
a) 4.387
b) Yes, because np & npq are greater than 10.
c) = 0.017
Step-by-step explanation:
Give data:
p = 0.69
n = 90
a) a
E(X) = np = 62.1
= 4.387
b)
np = 62.1
q = 1 - p = 1 - 0.69 = 0.31
npq = 19.251
Yes, because np & npq are greater than 10.
c.
[continuity correction]
= P(Z> 2.14 )
= 1 - P(Z<2.14)
= 1 - 0.983 (using table)
= 0.017
