Solve this linear system 28x + 44y = 964.40 21x + 33y = 723.30
Sladkaya [172]

28x + 44y = 964.40

21x + 33y = 723.30

Let's multiply the first equation by 4 and the second by -4

84x + 176y = 3857.6

-84x - 132y = -2893.2

Add the equations together.

0 + 44y = 964.4

Simplify

44y = 964.4

Divide both sides by 44

y = 964.4/44

Since we have the value of y, let's plug 964.4/44 into y for the first equation.

28x + 44(964.4/44) = 964.40

Simplify the left side

28x + 964.4 = 964.4

Subtract 964.4 from both sides

28x = 0

Divide both sides by 0

x = 0

In conclusion,

y = 964.4/44

x = 0

Suppose a computer chip manufacturer rejects 2% of the chips produced because they fail presale testing. a) What’s the probabili
Bess [88]

Answer:

a) 0.0184

b) 0.1829

Step-by-step explanation:

a) With geometric distribution you can measure the number of trials until the first success, that is, a defective chip is found, as follows:

P(x = k) = p*(1-p)^(k-1)

This means: probability to find exactly 1 defective in k trials, p is the probability to find a defective chip, which is equal to 0.02, and the number of trials are k = 5. Replacing:

P(x = 5) = 0.02*(1-0.02)^(5-1) = 0.0184

b) If you want the probability of 1 success within k trials, compute:

P(x

Replacing with k = 10

P(x
