Answer:
p(z<0.42) = 0.6628
Step-by-step explanation:
A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. That is to say:
μ = 0
σ² = 1
Using a calculator, we find that:
p(z<0.42) = 0.6628 (See picture attached)
Since Sin is equal to opposite over hypotenuse
so that's mean Sin(60°) =
#I just rounddown from angle 65° to 60° as the number is not that much different.
and Sin(60°) is equal to
so we got Sin(60°) = =
x =
x ≈ 14
then we can answer C)14.5
the answer D) is not correct for sure because the opposite cannot be longer than hypotenuse in the Right Triangle form.
