There are no factors for 13 because 13 is a prime number, where the only factors it has are 1 and itself.

A 10 sided die is numbered 1-10 if you roll it 60 times what is the best prediction for how many times you would eithrr a 1 or 2
Kamila [148]

Answer: 12

Step-by-step explanation:

So if its 1-10, and you can either roll a 1 or 2, it would be 2/10, then simplified to 1/5, and in order to get the answer you need to multiply it by 60

1/5 x 60/1 = 12

(sorry if I got it wrong, feel free to correct me if I did)

8 : 8  16  24  32  40  48  56

12 : 12  24  36  48

The number that they both have (least) in common is 24.

What's the difference between a independent variable and dependent variable
Travka [436]

Answer:

The dependent variable depends on the independent variable.

Step-by-step explanation:

  • The variable whose values are deliberately changed by the researcher in order to obtain the desired outcome is called independent variable...
  • The values of the independent variable can be changed as per requirement, by the researcher...
  • Manipulation can be done in the values of independent variable, but the researcher observes the value of a dependent variable during an experiment.
  • An independent variable is a presumed cause whereas dependent variable is a measured effect.
  • In a simple linear regression, ‘y’ denotes dependent variable while ‘x’ denotes independent variable, which means y depends on x

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.

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.
