Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = πd ( d is the diameter )
(4)
Here d = 18, thus
C = 18π in
(5)
Here C = 50π, thus
πd = 50π ( divide both sides by π )
d = 50 in
The radius r is one half of the diameter , thus
r = 50 ÷ 2 = 25 in
Answer and Step-by-step explanation: The null and alternative hypothesis for this test are:
To test it, use F-test statistics and compare variances of each treatment.
Calculate F-value:
F = 1.8356
The <u>critical value of F</u> is given by a F-distribution table with:
degree of freedom (row): 20 - 1 = 19
degree of freedom (column): 20 - 1 = 19
And a significance level: α = 0.05
= 2.2341
Comparing both values of F:
1.856 < 2.2341
i.e. F-value calculated is less than F-value of the table.
Therefore, failed to reject 
, meaning there is <u>no sufficient data to support the claim</u> that sham treatment have pain reductions which vary more than for those using magnets treatment.

Step-by-step explanation:
12.09<12.4<12.5<12.8
The interior angel for this parallelogram is 360° because
180°(n-2) where n represent the total side.
Angle 1+ Angle 3=70°
360°-70°=290°
290°÷2=145°. As a result, the measurements of D2 is D. Hope it help!
