Answer:
No matter how big or small they are, they all have the same surface area, and they can't be changed.
Answer:
<em> The 99% confidence interval for the mean repair cost for the VCRs</em>
(65.801, 85.199)
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Mean of the sample(x⁻) = $75.50
Given the standard deviation of the sample (S) = $18.07
Given the size of the sample 'n' = 22
Degrees of freedom = n-1 =22-1 =21
critical value t₍₀.₀₁, ₂₁₎ = 2.5176
<em> The 99% confidence interval for the mean repair cost for the VCRs</em>
( 75.50 - 9.699 , 75.50 + 9.699 )
(65.801, 85.199)
<u><em>Final answer:-</em></u>
<em> The 99% confidence interval for the mean repair cost for the VCRs</em>
(65.801, 85.199)
It cause trenches because it creates holes on the earth's crust
Answer:
To prove triangles are similar, you need to prove two pairs of corresponding angles are congruent
Step-by-step explanation:
SSS similarity postulate
The SSS similarity postulate says that if the lengths of the corresponding sides of two triangles are proportional then the triangles must be similar.
In the given figure , we have two triangles ΔABC and ΔXYZ such that the corresponding sides of both the triangles are proportional.
i.e.
Then by SSS-similarity criteria , we have
ΔABC ≈ ΔXYZ
