The greatest common factor of 15 and 40 is 5. (Factors of 15: 1,3,5,15)
(Factors of 40: 1,2,4,5,8,10,20,40)
We know that
the addition rule states that
P(A or B) = P(A) + P(B) − P(A and B)
in this problem
P(A)=0.72
P(B)=0.84
P(A and B)=0.64
so
P(A or B) = P(A) + P(B) − P(A and B)-----> 0.72+0.84-0.64
P(A or B) = 0.92
the answer is
0.92 (92%)
I believe the answer is B, since what I was taught is that the reason the input is not the same is because energy gets wasted on other forms of outputs, such as heat, sounds, whatever your device isn’t meant to do.
Answer:
Option D is the answer hope it helps :)
Step-by-step explanation:
The distrance to be travelled is 8/10 - 2/25 therefore:
Total dlistance = 81/10 - 12/5
add using least common denominator:
Total distance = 81 - 12 x 2
10
evaluate: Total distance = 57/10 = 5.7
according to the given information if they travel at a speed of 3 miles per house and there are 12-10= 2 hours, so the distance travelled to noon will be 2x = 6 miles - 5.7 miles. This implies that they will be able to reach the 8 1/10 mark by noon.
