What is the slope of the line passing through

(- 3, - 3); (2, 5)

https://socratic.org/questions/what-is-the-slope-of-the-line-passing-through-3-3-2-5

\frac{8}{5}

Explanation: Slope of a line passing through points x1,y1 and x2,y2 is

\frac{y 2 - y 1}{x 2 - x 1}

. In this, the slope would therefore ...

< 2, - 3, - 1 >

< - 8, 3, - 5 >

https://socratic.org/questions/what-is-the-angle-between-2-3-1-and-8-3-5

cos θ = \frac{< 2 , - 3 , - 1 > \cdot < - 8 , 3 , - 5 >}{( 2 ^{2} + ( - 3 ^{2} ) + ( - 1 ) ^{2} ) ( ( - 8 ) ^{2} + 3 ^{2} + ( - 5 ) ^{2} )}

2 - 3 + 1 = 0

: What divisibility test is this?

https://math.stackexchange.com/questions/2886205/11-mid-231-because-2-3-1-0-what-divisibility-test-is-this

It is this test: if the decimal expansion of a number

n

d_{k} d_{k - 1} \dots d_{1} d_{0}

11 ∣ n

n ∣ d_{0} - d_{1} + d_{2} - \dots + (- 1)^{k} d_{k}

. This follows from the fact that

n = \sum_{j = 0}^{k} d_{j} 1 0^{j}

probability of sequence of exactly 3 heads
