Answer/Step-by-step explanation:

1. The vertex of am angle is formed when two lines join together. The vertex of the angle shown in the diagram is located outside the circle.(<R)

2. The lines that created <FRT (lines FR & TR) are secants

3. The major arc = FT = 140°

minor arc = QS = 44°

4. Formula of Exterior angles of a circle = (major arc - minor arc)/2

x = (140 - 44)/2

x = 96/2

x = 48°

A pharmaceutical company receives large shipments of aspirin tablets. The acceptance sampling plan is to randomly select and tes

Pavel [41]

Answer:

0.818

Step-by-step explanation:

Since the shipment has a ton of aspirin tablets, we can assume that we pick 13 of them with reposition, because the probability shoudn't change dramatically from the probability of picking without reposition if we do so.

We call D the amount of defective tablets. If we assume that we pick the tablets with reposition, then we obtain that D is a random variable of Binomial distribution with parameters 13 and 0.6 (the probability of picking a defective tablet).

We want D to be at most one. To calculate the probability of that event we add up the probability of D being equal to 0 and the probability of D being equal to one. Since D is binomial, we have

$P(D = 0) = (1-0.06)^{13} = 0.447$
$P(D = 1) = {13 \choose 1} * 0.06^1 * (1-0.06)^{12} = 13*0.06*0.94^{12} = 0.371$

We conclude that

$P(D \leq 1) = P(D = 0) + P(D = 1) = 0.447+0.371 = 0.818$

Hence, the shipment will be accepted with probability 0.818

I hope this helps you!

Arnold's Pizzeria sells their pizzas "by fraction". You can buy 1/6 of a pizza for $2.75, 2/5 of a pizza for for $6, 1/2 of a pi

Ugo [173]

Answer: 2/5 of a pizza for for $6 offers the best deal.

Step-by-step explanation:

Pizzas are sold by fraction at Arnold's Pizzeria.

1)You can buy 1/6 of a pizza for $2.75. This means that the cost of a full pizza at this rate would be

6 × 2.75 = $16.5

2) 2/5 of a pizza for for $6, This means that the cost of a full pizza at this rate would be

6 × 5/2 = $15

3) 1/2 of a pizza for $8. This means that the cost of a full pizza at this rate would be 8 × 2 = $16

4) 2/3 of a pizza for $12. This means that the cost of a full pizza at this rate would be 12 × 3/2 = $18

Therefore, the best deal is 2/5 of a pizza for for $6
