About 80% of the egg rolls sold in the US grocery stores are made in Houston Texas .A skilled wrapper can make 4,000 egg rolls i

alukav5142 [94]

If a skilled wrapped does 4000 egg rolls in an 8-hour day, then he does 4000 / 8 = 500 egg rolls per hour. It means that he can make 500 / 60 = 8,(33) egg rolls per minute. So Bettie's claim is not reasonable.

It would be reasonable if the wrapper would make 1 * 60 = 60 egg rolls per hour and 60 * 8 = 480 egg rolls in one shift. So she's far away from truth :)

Hope this helps!

Hello from MrBillDoesMath!

Answer:

The correct answer is p >= -5/3

but I don't see that answer as a provided choice (?)

Discussion:

Solve:

2(6p-5) >= 3(p-8) - 1 =>

2*6p - 2*5 >= 3*p - 3*8 -1 =>

12p -10 >= 3p - 24 - 1 => (subtract 3p from both sides)

12p-3p - 10 >= -25 => (add 10 to both sides)

9p >= -25 + 10 = -15 =>

p >= -15/9 = -5/3

Suppose you just received a shipment of twelve televisions. Three of the televisions are defective. If two televisions are rando

qwelly [4]

Answer: The probability that both televisions work is 0.5625 .

The probability at least one of the two televisions does not work is 0.4375.

Step-by-step explanation:

Given : Number of televisions received in shipment= 12

Number of defective televisions received in shipment= 3

Then proportion of defective televisions = $\dfrac{3}{12}=0.25$

Using binomial probability formula, the probability of getting success in x trials is given by :-

$P(x)=^nC_xp^x(1-p)^{n-x}$

If two televisions are randomly selected, then the probability that both televisions work will be :-

$P(0)=^2C_0(0.25)^0(0.75)^2=(0.75)^2=0.5625$

The probability at least one of the two televisions does not work will be :-

$P(x\geq1)=1-P(0)=1-0.5625=0.4375$
