Answer:
Nope
Step-by-step explanation:
To now if a triangle is a right angle, use Pythagoras Theorem,
a^2 + b^2 = c^2
C usually be the longest side of the triangle, C = 17
Then also let a and b be 6 and 13 respectively.
6^2 + 13^2 =205
C^2 = 205
C = sqrt(205) = 14.32
therefore no this is not a right angle triangle
x = number of hours
want to find probability (P) x >= 13
x is N(14,1) transform to N(0,1) using z = (x - mean) / standard deviation so can look up probability using standard normal probability table.
P(x >= 13) = P( z > (13 - 14)/1) = P(z > -1) = 1 - P(z < -1) = 1 - 0.1587 = 0.8413
To convert that to percentage, multiply 100, to get 84.13%
Step-by-step explanation:
Hey there!
Given;
The points is; (-1 , 2) and slope is 4.
<em>Note:</em><em> </em><em>Use </em><em>one-point</em><em> formula</em><em>.</em>
<em>
</em>
<em>~</em><em> </em><em>Put </em><em>all</em><em> values</em><em>.</em>
![(y - 2) = 4(x + 1)](https://tex.z-dn.net/?f=%28y%20-%202%29%20%3D%204%28x%20%2B%201%29)
~ Simplify it.
![(y - 2) = 4x + 4](https://tex.z-dn.net/?f=%28y%20-%202%29%20%3D%204x%20%2B%204)
![4x - y + 6 = 0](https://tex.z-dn.net/?f=4x%20-%20y%20%2B%206%20%3D%200)
Therefore, the required equation is; 4x-y+6=0.
