If the random variable x is normally distributed with a mean equal to .45 and a standard deviation equal to .40, then P(x ≥ .75)

stellarik [79]

P(x ≥ 0.75) = P(z ≥ (0.75 - 0.45)/0.40) = P(z ≥ 0.30/0.40) = P(z ≥ 0.75) = 1 - P(z < 0.75) = 1 - 0.077337 = 0.22663

A circle with a radius of 12 would have a circumference of ____

kogti [31]

Answer:

$\huge\boxed{75.36}$

Step-by-step explanation:

In order to find the circumference of a circle, we can use the formula for it, which is $2 \pi r$ .

This formula states that r, the radius, multiplied by pi (3.14..) doubled will be the circumference.

Pi rounds to 3.14 usually.

So our new formula is:

$2 \cdot 3.14 \cdot 12$

We can now multiply.

$3.14 \cdot 2 = 6.28\\\\6.28 \cdot 12 = 75.36$

Hope this helped!
