So, we can define probability as the following ratio: Number of successful outcomes over Number of total outcomes. Suppose we define an event to be the drawing of one transistor from the lot. If we want to calculate the probability that it is defective, a "successful" event would be drawing a defective transistor. Hence there is 1 successful event. But we can choose from 500 transistors, hence there are 500 total outcomes. Thus, the ratio that defines the probability P is: p=1/500. Calculating this, yields that p=0.002 or p=2%
Answer:
21 to 28
Step-by-step explanation:
Reduce each ratio to lowest terms by dividing by any common factors. (It helps to know your multiplication tables, or a quick way to find the greatest common divisor.)
15 : 20 = (5*3) : (5*4) = 3 : 4
_____
21 : 28 = (7*3) : (7*4) = 3 : 4 . . . . same as 15 : 20
5 : 10 = (5*1) : (5*2) = 1 : 2 . . . . . ≠ 3:4
18 : 25 . . . has no common factors . . . ≠ 3:4
Answer:
the rate per mile or cost per mile
Step-by-step explanation:
2.9 the rate per mile he has to pay. it gives him the cost of the travel after a specific distance. this is excluding the the flat charge of 4.5 he has to pay.
Answer:
18
Step-by-step explanation:
100% of 6 is 6 so 300% (which does not actually exist) would be 3 times as much. 6x3=18
D. N/88=16
quotient means divisions so the quotient of a number and 88 is n/88.
