The wind-chill index is modeled by the function below where T is the temperature (°C) and v is the wind speed (km/h).

1 answer:

6 0

When T= 13°C and v = 34 km/h
W = 13.12 + 0.6215(13) - 11.37(34)^0.16 + 0.3965(13)(34)^0.16 = 13.12 + 8.0795 - 11.37(1.7581) + 5.1545(1.7581) = 21.1995 - 19.9893 + 9.0620 = 10.27°C.

If T decrease by 1°C (T = 12°C), then
W = 13.12 + 0.6215(12) - 11.37(34)^0.16 + 0.3965(12)(34)^0.16 = 8.95°C
Therefore, W decreased by 10.27°C - 8.95°C = 1.3°C

If v increases by 1 km/h (v = 35 km/h), then
W = 13.12 + 0.6215(13) - 11.37(35)^0.16 + 0.3965(13)(35)^0.16 = 10.22°C
Therefore, W decreaseb by 10.27°C - 10.22°C = 0.05°C

Suppose the probability of producing a defective light bulb from a production line is the same over an interval of 90 minutes. W

butalik [34]

Answer:

C) Uniform distribution

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely. In this case, the probability of producing a defective light bulb from a production line is the same over an interval of 90 minutes, so the correct answer is C.

We can calculate the probability.

Uniform probability distribution

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

$P(X \leq x) = \frac{x - a}{b-a}$

For this problem, we have that:

Uniformily distributed over a 90 minute interval, that is, between 0 and 90, so $b = 90$ and $a = 0$ .

We want to find $P(X \leq 15) = \frac{15-0}{90-0} = 0.167$

Marizza181 [45]

Since six necklaces all together costs 31.80 to make, I divided 31.80 by 6 and got 5.3. That means that to make one necklace, they'd spend $5.30. The beads alone for 1 necklace cost $2.70, so I subtracted that from the $5.30.

Answer: Each pendant costs $2.60
