Answer:
two over fifty five......
Answer:
N = 53°
Step-by-step explanation:
1. 55 + 72 = 127°
2. 180° - 127° = 53°
3. Angle N is 53°
I hope this helps in any way:)

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>
![(x^{-} - t_{0.01} \frac{S.D}{\sqrt{n} } , x^{-} +t_{0.01} \frac{S.D}{\sqrt{n} })](https://tex.z-dn.net/?f=%28x%5E%7B-%7D%20-%20t_%7B0.01%7D%20%5Cfrac%7BS.D%7D%7B%5Csqrt%7Bn%7D%20%7D%20%2C%20x%5E%7B-%7D%20%2Bt_%7B0.01%7D%20%5Cfrac%7BS.D%7D%7B%5Csqrt%7Bn%7D%20%7D%29)

( 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)
Answer:
y - 5 = -3(x + 3)
Step-by-step explanation:
A parallel line has the same slope but different y-intercept
So the slope of our line is -3
We also have our x1 and y1
So input that into the point-slope formula : y - y1 = m(x - x1)
- y -y1 = m(x - x1)
- y - 5 = -3(x - (-3))
- y - 5 = -3(x + 3)
The equation of the line is ![\boxed{\text{y - 5 = -3(x + 3)}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Ctext%7By%20-%205%20%3D%20-3%28x%20%2B%203%29%7D%7D)
