Step-by-step explanation:

AC²=AB²+BC²

=(7)²+(13)²

=49+169= 218

AC=√218

= 14.7ft

therefore the original height of the tree

=7+14.7

=21.7ft

Pamelas age is. 2 times jiris age. The sum of their ages is 30.what is jiris age?

Anettt [7]

Answer: 10

p = Pamela’s age, j = Jiris’ age

2j = p
p + j = 30

Then change things around a bit...
p + j = 30 or
30 - p = j

Then substitute
2(30 - p) = p

And solve
2(30 - p) = p
60 - 2p = p
60 = 3p
p = 20

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!
