Answer:
D. Alice used empirical probability, Mark used theoretical probability.
Step-by-step explanation:
Alice used empirical probability because she actually flipped the coin 100 times but Mark assumed the coin was fair and didn't actually test it, using theoretical probability.
Times the corner and bases
I don't think its possible to do this... you have to have 2 equations
Answer:
8i+3j
Step-by-step explanation:
let point P2(0,3)
point P1(-8,0)
vector P1P2= Position vector of P2- position vector of P1
vector= (0,3)-(-8,0)
vector= (8,3)
vector=8i+3j
Answer:
B
Step-by-step explanation:
If you are allowed to use a graphing calculator, this can solve a lot of time. Graphing y = (x - 705)(x - 795) + 800(x - 750)(x - 835) gets us a parabola with x-intercepts of 749.97 and 834.924.
These roots are real and distinct, or choice B.
If you aren't allowed to use a graphing calculator, you can expand and combine like terms to get 801x^2 − 1269500x + 501560475. Looking at the discriminant, we see that (−1269500)^2 - 4*801*501560475 = 4630488100 is greater than 0 and not a perfect square, so it is real and distinct, or choice B.
I hope that helps!
