What is EG? <br><br> I need help

n200080 [17]

Answer:

Step-by-step explanation:

y/x = 30/(x + 10)

(y + 12)/x = 54/(x + 10)

y/x + 12/x = 54/(x + 10)

30/(x + 10) + 12/x = 54/(x + 10)

30x + 12(x + 10) = 54x

30x + 12x + 120 = 54x

120 = 12x

x = 10

EG = x + x + 10

EG = 10 + 10 + 10

EG = 30

A company has 2 machines that manufacture widgets. An older machine manufactures 25% defective widgets, while the new machine ma

Bingel [31]

Answer:

73.90%

Step-by-step explanation:

Let Event D=Defective, D' = Non Defective

Let Event N=New Machine, N' = Old Machine

From the given information:

$P(D|N')=0.25\\P(D|N)=0.09\\P(N)=0.7\\P(N')=0.3$

We are required to calculate the probability that a widget was manufactured by the new machine given that it is non defective.

i.e. $P(N|D')$

$P(D'|N')=1-P(D|N')=1-0.25=0.75\\P(D'|N)=1-P(D|N)=1-0.09=0.91$

Using Baye's Law of conditional Probability

$P(N|D')=\dfrac{P(D'|N)P(N)}{P(D'|N)P(N)+P(D'|N')P(N')} \\=\dfrac{0.91*0.7}{0.91*0.7+0.75*0.3}\\ =0.73897\\\approx 0.7390$

Therefore given that a selected widget is non-defective, the probability that it was manufactured by the new machine is 73.9%.

You are given a standard deck of 52 cards. Three cards are chosen at random with replacement. What is the probability of choosin

geniusboy [140]

Answer:

Probability = 0.23

Step-by-step explanation:

Probability of picking it choosen those at random without replacement =Pr(ace) + Pr(spade)+Pr(a four)

Probability = 4/52 + 4/52 + 4/52

Probability= 3(4/52)

Probability = 0.23
