Answer:
Idk about abc they are all wrong but the answer is x-3/y
Step-by-step explanation:
There's a lot of ways! So, you can plug in and solve, solve for the two roots, solve for the vertex form, and solve for the standard form. Multiple ways!
Answer:
a) 91.4%
b) 37.6%
c) 26.8%
Step-by-step explanation:
For each of these, we'll get a z-score, then use our calculators to find the area using normalcdf (on TI-84, 2nd->VARS->2)
a) z = (9-6.4) / 1.9 = 1.368
normalcdf(-999,1.368) = .914 = 91.4%
b) z = (7-6.4) / 1.9 = .316
normalcdf(.316,999) = .376 = 37.6%
c) normalcdf(.316,1.368) = .268 = 26.8%
Answer:
I think it will be 2/1
Step-by-step explanation:
Its positive I know that, but since the points go right two and up one that should be the slope if i'm not mistaken.
Wherever there is an x , plug in 20,000
