A rectangle has length 8cm the area is 20cm^2
nadya68 [22]

Answer:

Since Rectagle area is found by Length * Width, 20/8 would give the width of 2.5cm, if the length was increased by 2cm, and the area by 4cm, you would now do 24/10 to get the width which is 2.4, 5 percent of 2.5 is found by multiplying 2.5 by 0.05 which is 0.125, and 2.4 is only .1 less from 2.5 so yes noah is indeed correct, for that the width is decreased by less than 5%

A firm is accustomed to training operators who do certain tasks on a production line. Those operators who attend the training co
Alexus [3.1K]

Answer:

Probability = 0.58

Step-by-step explanation:

This problem is solve by using Baye's Probability.

Let P(A) = Probability that operator attended training course = 50% = 0.5

P(B) = Probability that operator not attended training course = 50% = 0.5

Also P(Q) = Probability that operator meet their production quotas

Then, P(Q|A) = 90% = 0.9

P(Q|B) = 65% = 0.65

P(A|Q) = ?

Then by Baye's Theorem,

P(A|Q) = \dfrac{P(Q|A) \times P(A)}{P(Q|A) \times P(A)+P(Q|B) \times P(B)}

⇒  P(A|Q) = \dfrac{0.9 \times\0.5 }{0.9 \times\0.5+0.65 \times\0.5}

⇒ P(A|Q) = 0.58

which is required probability.
