The number of degrees of freedom is 29.

<h3>What is degree of freedom?</h3>

A degrees of freedom inside a statistical method describe how many values in a computation can vary. The degrees of freedom of chi-square tests, t-tests, and even more complex f-tests can be calculated to assist confirm their statistical validity.

These tests are frequently used to have a data with the data that would anticipated to be obtained if a given hypothesis were followed.

Degrees of Freedom Formula:

The statistical formula for determining degrees of freedom is straightforward. It is written as follows: degrees of freedom are the number of values in such a data set minus one.

df = N-1

Where N denotes the total number of items in the data collection (sample size).

Now according to the question,

Its degrees of freedom will be determined using the method df = N-1:

df = 30-1 = 29 appears in this case.

This means that in this data collection, three integers can vary as long even as mean remains 20.

Answer:

6) 4 (tiny 5) in the upper corner

7) 9 (tiny 2) in the upper corner

8) 4 (tiny 2) in the upper corner

9) 3 (tiny4) in the upper corner

10) 5 (tiny 5) in the upper corner

Step-by-step explanation:

Once you get the hang of it, it's quite easy! Here are the steps for how I figured it out:

1) Figured out what number they are giving me. For the first one, I saw that they gave me the number 4. For the second one, they gave me the number 9 etc.

2) Next, I looked at each problem individually. For the first one, you know that they are giving you the number 4. You would then count the amount of numbers, in this case 4, that you see in the equation.

3) Now knowing the numbers of numbers in the equation, you'd write it in exponential notation. For the first one, they are giving you the number 4, however, they are giving it to you 5 times. Thus, by writing the number 5, smaller than the number 4, you are allowing you and your math teacher to know that you have to take the number 4 and multiply it by itself 5 times.

4) Try doing this for the others too. Trust me, once you get the hang of it, it's pretty simple. Hope this helped!

How many years (to two decimal places) will it take $15000 to grow to $17500 if it is invested at 8% compounded semi- annually?
VLD [36.1K]

Answer:

1.97 years

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 8/100

r = 0.08 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(17,500.00/15,000.00) / ( 2 × [ln(1 + 0.08/2)] )

t = ln(17,500.00/15,000.00) / ( 2 × [ln(1 + 0.04)] )

t = 1.965 years

Solve the equation. −3=h+8÷2 h=?
Nimfa-mama [501]

Answer:

h = -7

Step-by-step explanation:

  1. 8 ÷ 2 = 4
  2. Plug 4 in: -3 = h + 4
  3. Subtract 4 from each side, so it now looks like this: -7 = h

I hope this helps!
