Answer:
0.9815
Step-by-step explanation:
P(head) = 0.55
P(tail) = 1 - 0.55 = 0.45
P(Atleast one head)
= 1 - P(all tails)
= 1 - 0.45⁵
= 0.9815471875
= 0.9815
Answer:
71 degrees.
Step-by-step explanation:
m < CED = 180 - 152 = 28 degrees ( adjacent angles).
m <BAC = 28 degrees( alternate angles).
m < ACD = 28 + 43 = 71 degrees (external angle theorem).
Answer:
1). m° = 56.1°
2). X= 91.8 mm
Step-by-step explanation:
For angle m°
Using the sine rule
15.1/sin m= 18.2/sin 90
But Sin 90= 1
15.1/sin m= 18.2
15.1= 18.2*sin m
Sin m = 15.1/18.2
Sin m=0.8297
m= sin^-1(0.8297)
m= 56.06°
m° = 56.1°
For length of side x
Using sine rule
X/sin 61= 105/sin 90
But sin 90= 1
X/sin 61= 105
X = sin61 *105
X=0.8746*105
X= 91.833 mm
X= 91.8 mm
Step-by-step explanation:
35×3=105 with 5 left over
So it would be 4 group
3 groups of 35 and 1 group of 5
So it would be 4 groups
