Answer:

1.618

The Fibonacci sequence is significant because of the so-called golden ratio of 1.618, or its inverse 0.618. In the Fibonacci sequence, any given number is approximately 1.618 times the preceding number, ignoring the first few numbers.

A simple random sample of earthquake depths yields the following:

GREYUIT [131]

The critical value becomes 2.584 for two tailed test since we have to reject the null hypothesis, t >2.584 or t < -2.584 test stat lie in the rejection region, we have to reject the null hypothesis or claim incorrect.

Data;

mean = 5.82
s = 4.93
n = 600

<h3>Test-Static t </h3>

Let's calculate the t-value

$t = \frac{x - \mu}{\frac{s}{\sqrt{n} } }$

Substitute the values into the equation and solve;

$t = \frac{x - \mu}{\frac{s}{\sqrt{n} } } \\t = \frac{5.82 - 5}{\frac{4.93}{\sqrt{600} }} \\t = \frac{0.82}{0.201} \\t = 4.079$

The t-value is 4.079.

The allowed significance value = 0.01

The degree of freedom is n -1, which becomes 600 - 1 = 599.

Coley bought 10 books which cost $2m each. If she gave the cashier a fifty dollar bill, how much change would she receive?

dybincka [34]

To find the answer first we will multiply to see how much the books cost. Then we will subtract 50 by the amount of money she has to pay. Then we will check our work to makes sure we are %100 right. Lets do it:-

Lets multiply:-
10 × 2 = 20
So, 10 books cost 20m.

Lets subtract:-

50 - 20 = 30
So she gets 30m in chage.

CHECK OUR WORK:-

30 + 20 = 50
We were RIGHT!!!

So, Coley would receive 30m (B) 30m) in change is she pays with a 50 dollar bill.

Hope I helped ya!!
