Answer:

0.8 lbs

Step-by-step explanation:

Ounces are typically used to measure liquid, so I would discourage choosing the top two. And, hopefully you know by now that an orange does not weigh 8 pounds.

Answer:

(a) 0.8 ounces (most precision)

(b) 8 ounces (best precision for likely weight of an orange)

Step-by-step explanation:

The most precision is obtained by using the smallest unit of measure. On this list, the smallest unit of measure is a tenth of an ounce. That is, the measure 0.8 ounces has the most precision.

It is unlikely that the weight of one orange will be 0.8 ounces. The smallest unit used in a measurement likely to correspond to the weight of an orange is 1 ounce, used in the measurement 8 ounces. That measurement has better precision than 0.8 pounds, because 0.1 pounds corresponds to 1.6 ounces.

Answer: Probability that a randomly selected unit will contain at least two surface- finish defect is 0.04.

Step-by-step explanation:

Since we have given that

Mean rate defects per unit = 0.3

Since we will use "Poisson distribution":

$P(X=K)=\frac{e^{-\lambda}\lambda^k}{k!}$

But we need to find the probability that a randomly selected unit will contain at least two surface-finish defect.

$P(X\geq 2)=1+P(X=0)+P(X=1)$

So,

$P(X=0)=\frac{e^{-0.3}0.3^0}{0!}=e^{-0.3}=0.74\\\\P(X=1)=\frac{e^{-0.3}\times 0.3}{1}=0.22$

so, it becomes,

$P(X>2)=1-(0.74+0.22)=1-0.96=0.04$

Hence, probability that a randomly selected unit will contain at least two surface- finish defect is 0.04.

Airida [17]

Answer:

C. When Helen rents 3 DVDs per month, either service will cost her $22.50 per month.

Step-by-step explanation:

y = 15.00 + 2.50x

y = 12.00 + 3.50x

When x = 2

y = 15.00 + 2.50x

= 15.00 + 2.50(2)

= 15.00 + 5.00

= 20.000

y = 12.00 + 3.50x

= 12.00 + 3.50(2)

= 12.00 + 7.00

= 20.00

When x= 4

y = 15.00 + 2.50x

=15.00 + 2.50(4)

= 15.00 + 10.00

= 25.00

y = 12.00 + 3.50x

= 12.00 + 3.50(4)

= 12.00 + 14.00

=26.00

When x = 3

y = 15.00 + 2.50x

= 15.00 + 2.50(3)

= 15.00 + 7.50

= 22.50

y = 12.00 + 3.50x

= 12.00 + 3.50(3)

= 12.00 + 10.50

= 22.50

When x = 6

y = 15.00 + 2.50x

= 15.00 + 2.50(6)

= 15.00 + 15.00

= 30.00

y = 12.00 + 3.50x

= 12.00 + 3.50(6)

=12.00 + 21.00

= 33.00

The correct answer:

C. When Helen rents 3 DVDs per month, either service will cost her $22.50 per month.
