Alinara [238K]2 years ago
8 0

Answer:

Frequency refers to the number of waves that pass a given point in a given time period and is often expressed in terms of hertz (Hz), or cycles per second. Longer wavelengths will have lower frequencies, and shorter wavelengths will have higher frequencies

PLEASE HELP ASAP <br> TRIGONOMETRY
otez555 [7]

Answer:

11). x = 25.8°

12). x = 67.3°

Step-by-step explanation:

11). By using sine rule in the given triangle,

   cos(x) = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

   cos(x) = \frac{27}{30}

   x = \text{cos}^{-1}(\frac{9}{10} )

   x = 25.84

   x ≈ 25.8°

12). By applying tangent rule in the given triangle,

    tan(x) = \frac{\text{Opposite side}}{\text{Adjacent side}}

    tan(x) = \frac{43}{18}

    x = \text{tan}^{-1}(\frac{43}{18} )

    x = 67.29°

    x ≈ 67.3°

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
