Identify the equation whose graph is a vertical line. A B C y = Ž - 1 y = 0 x = 0

<u>Answer:</u>
- x = 0
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- Formula: y = mx + b
<em>If the line is a vertical line on a graph, then this means that the </em><em>x coordinate is 0</em><em> while the </em><em>y-intercept is un-identified.</em><em> Looking at the options and the formula, </em><em>x = 0 </em><em>is the most reasonable option because a </em><em>vertical line on a coordinate plane basically defines that the x coordinate is 0.</em>
Hence, x = 0 must be correct.
Hoped this helped.

Use the tangent-chord theorem:
The included chord-tangent angle is half the size of the intercepted arc.
The intercepted arc is "c".
The included chord-tangent-angle is the supplement of 110=70 degrees.
Therefore from the tangent-chord theorem, 70 degrees = half the size of arc "c"
=>
arc "c" = 2*intercepted angle = 2*70 degrees = 140 degrees.

Step-by-step explanation:
let the money on bet is X.
probability of winning =18/38=9/19
probability of losing =(1-9/19)=10/19
expected outcome =probability *return =(
Expected value of return after one bet is =(9/19*x)-(10/19*x)=-1x/19
it is negative which is obvious cause casinos are there to earn money.
a) Our best strategy in this case as probability of winning is near by 50 %, we should place a bet of 1 $ each,and when we lose one bet consecutively we should bet twice the amount..
Cause two consecutive losses on black has less probability.
c) In case we have to reach 30 $ we have to use the same strategy as above.
