Answer:

The answer is 0.0099

Explanation:

The mean of sample is 0.08.

The standard deviation of the sample is:

s = √(0.08 (1 − 0.08) / 1000)

s = 0.00858

Since n > 30, we can approximate this as a normal distribution.  The z score is:

z = (0.1 − 0.08) / 0.00858

z = 2.33

Using a z-score table:

P(x > 2.33) = 1 − 0.9901

p(x > 2.33) = 0.0099

What is the smallest defined unit of time on the geological scale?
worty [1.4K]
I believe that the smallest defined unit of time on the geological scale are ages.
Here are all of them, ranked from largest to smallest: eons, eras, periods, epochs, and ages.
Eons are very large chunks of time which encompass more than 500 years, whereas ages can last from a couple of years to about a hundred.

Find the measure of X, Y and Z in simplest form:
Inga [223]

Answer/Explanation:

12^2 = 16*x (altitude to hypotenuse theorem)

Solve for x using this equation

144 = 16x

\frac{144}{16} = x (division property of equality)

9 = x

x = 9

y^2 = 12^2 + x^2 (pythagorean theorem)

y^2 = 12^2 + 9^2 (substitution)

y^2 = 144 + 81

y^2 = 225

\sqrt{y^2} = \sqrt{225}

y = 15

z^2 = (x + 16)^2 - y^2 (pythagorean theorem)

z^2 = (9 + 16)^2 + 15^2 (substitution)

z^2 = 25^2 + 15^2

z^2 = 625 + 225

z^2 = 850

\sqrt{z^2} = \sqrt{850}

z = \sqrt{25*34}

z = 5\sqrt{34}
