Rewrite the parabola in standard form and use this formula to find the vertex (h,k).
= (2,-1)
Answer:
(7,7)
Step-by-step explanation:
Because going up would be moving along the y-axis, then you would add 5 to the Y value which was 2 so therefore, if you move up 5 you'll be at (7,7).:)
Answer:
1. no
2. 36+196=232 c=441 Obtuse.
3. x is greater than 3, less than 21.
Step-by-step explanation:
Answer:
0.9958
Step-by-step explanation:
P(being correct) = 1/4 = 0.25
Hence, p = 0.25
n = 19
P(x ≥ 1) = p(x = 1) + p(x = 2) +... + p(x = 19)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
However, to save computation time, we could use a calculator :
Using a calculator,
P(x ≥ 1) = 0.99577
P(x ≥ 1) = 0.9958
