Answer:
Pr(N < 4.2) = 0.295
Explanation:
given data
flow rate q = 300 veh/h
reaction time = 2.5 s
oncoming vehicle to stop = 1.7 s
solution
we know here that ongoing vehicle head way between successive vehicles is here greater than (1.5 + 2.5) = 4.2 second
so that driver pulling out will not be in an accident
and if head way is less than 4.2 seconds then driver pulling out will be accident
here q is 300 vehicles/hour,
then λ= 0.0833 vehicles/second
than probability will be
Pr(N < 4.2) = 1 - 
................ 1
put here value
Pr(N < 4.2) = 1 - 
Pr(N < 4.2) = 0.295
Answer: $184.34
Bess issued four checks with amounts $175.17, $175.53, $175.35,and $184.34. With the total amount she issued, she expected her balance based on her cash register to be $869.96, but as per bank statement, her balance is $1054.13.
To get the amount of check which is not cleared yet, we have to deduct the balance in the cash check register from that of the bank statement:
$1054.13-$869.96 =184.17
$184.34 is the best answer because it is the last he wrote and the discrepancy of 0.17 may be due to some bank charges Bess had not recorded.
Answer:
Macaroni and cheese is an inferior good.
Explanation:
From the information given in the question, we can assume that macaroni and cheese are considered as an inferior good for this consumer because there is an inverse relationship between the income level of this consumer and the quantity demanded for macaroni and cheese.
If there is 10% increase in the income of an individual then as a result quantity demanded of macaroni and cheese decreases by 15% and the price of this good remains constant. This shows that macaroni and cheese is an inferior good.
