1 answer:
Answer:0.48
Step-by-step explanation:
Given
Machine 1 Produced 392 satisfactory pistons and 98 unsatisfactory Piston
Machine 2 Produced 360 satisfactory pistons and 240 unsatisfactory Piston
Two balls are selected from batch
Probability of getting Satisfactory Piston From machine 1 is
Probability of getting Unsatisfactory Piston From machine 2 is
Probability that the piston chosen from machine 1 is satisfactory and from machine 2 is unsatisfactory

Answer:
2. 1- Experimental probability of rolling a 4 = 40%
3. 2- Theoretical probability is 3% greater than experimental probability.
Step-by-step explanation:
Experimental probability of rolling a 4 = 100 ×
= 100 × 0.4
= 40%
Experimental probability of getting at least one tail =
= 0.72
Theoretical probability of getting at least one tail =
= 0.75
Theoretical probability is 3% greater than experimental probability.
Answer:
Option A earns higher interest($84115.58)
the difference in interest between the two option is $197.9
Step-by-step explanation:
In the problem we are going to apply both the simple interest formula and compound interest formula and compare which has the best/higher returns
Given data
Principal P= $43,000
Rate r= 6%= 0.06
time t= 3years
n= 4 (applicable for compound interest compounded quarterly)
solving for option A gives her 6% compounded quarterly
the compound interest formula is
Interest is =$8411.58
solving for option B which gives her 6% simple interest annually
the simple interest formula is
Interest is= $8213.68
calculating the diference in interest between the two options we have
= $197.9
Option A earns higher interest
