Answer:
all quadrilaterals have at least one pair of parallel sides
Step-by-step explanation:
this this is true because all quadrilaterals starting from triangle has at least one pair of parallel sides
idk if you seen this but I try this
You can conclude that X is smaller than Y. For example:
(2,5)
2 + 5 = 7
2 - 5 = -3
Hope this helped!
Answer:
Slope= m = Δy/Δx = (y₂-y₁)/(x₂-x₁) = rise / run
Step-by-step explanation:
Hope that helps . Just plug in your values if you are given two points
for example: (3,4) = (x₂,y₂) (1,2) = (x₁,y₁)
Just substitute in the equation above
(4-2)/(3-1) = 2/2 =1
good luck
Answer:
[34,54]
Step-by-step explanation:
-The empirical rule states that the 95% of the sampled observations will fall within two standard deviations of the mean for a normally distributed population.
Where:
- 68% is the first standard deviation
- 95% is the second standard deviation about the mean
- 99.7% is the 3rd standard deviation about the mean.
-Therefore. the middle 95% interval is calculated as:
![CI=\mu+2\sigma\\\\=44\pm 2(5)\\\\=44\pm 10\\\\=[34,54]](https://tex.z-dn.net/?f=CI%3D%5Cmu%2B2%5Csigma%5C%5C%5C%5C%3D44%5Cpm%202%285%29%5C%5C%5C%5C%3D44%5Cpm%2010%5C%5C%5C%5C%3D%5B34%2C54%5D)
Hence, the interval is [34,54]
