Answer:
Multiple of 9
Step-by-step explanation:
Because 72 = 9 x 8
and 9 x 12 = 108
Answer: 0.8202
Step-by-step explanation:
Probability an adult was never in a museum = probability of success = p = 15% = 0.15
To find probability that 2 or fewer of the 10 samples selected were never in a museum is given by:
P(X=2) or P(X=1) or P(X=0).
Where
P(X=r) = nCr * p^r * q^n-r
and n=10, p =0.15, q=0.85
When r = 2
P(X=2) = 10C2 * 0.15² * 0.85^8 = 0.2759
When r = 1
P(X=1) = 10C1 * 0.15 * 0.85^9 = 0.3474
When r = 0
P(X=0)= 10C0 * 0.15^0 * 0.85^10 = 0.1969
Hence probability of having 2 or fewer adults who never visited the museum = 0.1969 + 0.3474+ 0.2759 = 0.8202
The resultant force in this item, is that which connects the heads of the magnitude of the given vectors. The magnitude of the resultant force can be calculated through the Pythagorean theorem which states that the square of the resultant force should be equal to the sum of the squares of the smaller forces. That is,
A² + B² = C²
Investigating the vector values,
A² + B² = (3.5 lb)² + (6.2 lb)² = 50.69 lb²
C² = (9.1 lb)² = 82.81 lb²
Since the Pythagorean theorem is not satisfied by the given set of forces then, the forces are not in right angle.
The answer to the question is letter C.
Answer:
x=55
Step-by-step explanation:
2x-27=83
2x=110
x=55
The highest common factor of 60 and 150 is 30
And the lowest is 10
