Answer:
A: ≈ 28.26 inches
B: ≈ 25.12 inches
Step-by-step explanation:
To find the circumference of a circle, the outside distance, you simply multiply the diameter by π, or 3.14....
A:
9 * 3.14... ≈ 28.26 inches
B:
8 * 3.14... ≈ 25.12 inches
Answer:
Step-by-step explanation:
Choosing two points on the dotted line to find equation of line.
The points are:
and
Slope of line can be calculated as:
Using point slope equation to find equation of dotted line.
where represents slope of line and represents y-intercept.
The y-intercept for the dotted line = 6 as it intersects the y-axis at (0,6)
So, the equation of line is:
The dotted line indicates that the line is not included in the solution.
The solution of the inequality is below the dotted line, so thus it would be less than the line.
So, the inequality would be:
I did 20x 18 n got 360 then i did 360x5 and 1800
The angle of cba is 3.408* if you wanna know
Answer and Step-by-step explanation: The <u>critical</u> <u>value</u> for a desired confidence level is the distance where you must go above and below the center of distribution to obtain an area of the desired level.
Each sample has a different degree of freedom and critical value.
To determine critical value:
1) Calculate degree of freedom: df = n - 1
2) Subtract the level per 100%;
3) Divide the result by 2 tails;
4) Use calculator or table to find the critical value t*;
For n = 5 Level = 90%:
df = 4
t = = 0.05
Using t-table:
t* = 2.132
n = 13 Level = 95%:
df = 12
t = = 0.025
Then:
t* = 2.160
n = 22 Level = 98%
df = 21
t = = 0.01
t* = 2.819
n = 15 Level = 99%
df = 14
t = = 0.005
t* = 2.977
The critical values and degree of freedom are:
sample size level df critical value
5 90% 4 2.132
13 95% 12 2.160
22 98% 21 2.819
15 99% 14 2.977
