Answer:
First you add all of the results together for a sum of 243. Then, you divide that sum, 243 by 10, the number of results in total. That means the average weight of 10 random raccoons out of 150 raccoons in that wildlife preserve, is 24.3 pounds. Her statement is not reasonable because Jean stated the average weight of ALL raccoons is 25 pounds.

Answer: 0.20833
Step-by-step explanation:
This is a case of inverse probability.
We first determine the probability that an item is defective generally.
To do this we sum the possible options of having the item produced from the first machine and is defective or having the item produced by the second machine and is defective or having the item produced by the third machine and is defective.
Mathematically,this becomes :
(0.2 * 0.05) + (0.3 * 0.03) + (0.5 * 0.01)
0.01 + 0.009 + 0.005 = 0.024.
Probability an item is defective in general = 0.024
Probability a third machine produces a defective item = 0.5 * 0.01 = 0.005.
Hence, given that the item is defective, the probability that it was produced by the third machine becomes:
= (probability of the item being produced from the third machine and is defective) / (probability of the item being defective in general)
= 0.005/0.024
= 0.20833.
$6.060606- because in this situation she has $10 and the rate is $1.65 with no additional rate or fee.
So you would need to do 10/1.65 and round it down to find the whole or keep the decimals to get an exact answer
Answer:6.060606

Step-by-step explanation:
The equation describes a velocity curve that has an asymptote of 80 ft/s. The skydiver will <em>never</em> have a velocity of 120 ft/s.
Answer:
y = 12
Step-by-step explanation:
∵ m∠ABC = 40
∵ BD ray is the bisector of ∠ABC
∴ m∠ABD = m∠CBD = 20
In 2 Δ BAD and BCD:
∵ m∠BAD = m∠BCD = 90°
∵ m∠ABD = m∠CBD = 20°
∵ BD is a common side in the two triangles
∴ ΔABD congruent to ΔCBD⇒(AAS)
∴ AD = CD
∴ 3y + 6 = 5y - 18
∴ 5y - 3y = 6 + 18
∴ 2y = 24
∴ y = 24/2 = 12
