kobusy [5.1K]

Answer:

\huge\boxed{x=12sin80=11.8}\\\huge\boxed{y=12cos80=2.1}

Step-by-step explanation:

Because sine = opposite over hypotenuse, simply multiply both sides by the hypotenuse to get:

hypotenuse * sinθ = opposite

Do the same thing with cos to get:

hypotenuse * cosθ = adjacent

Birth weights are normally distributed with a mean of 3419 g and a standard deviation of 494 g. If a hospital plans to set up sp
Bas_tet [7]
Let X represent a random variable representing the birth weights of babies, and let x be the required cut-off, then
P(X < x) = 0.02
P(z < (x - 3419)/494) = 0.02
1 - P(z < (3419 - x)/494) = 0.02
P(z < (3419 - x)/494) = 1 - 0.02 = 0.98
(3419 - x)/469 = 2.04
3419 - x = 956.76
x = 3419 - 956.76 = 2462.24

Therefore, the weight to be used as cut-off is 2462.24 g
