Answer:
The expected answer is ...
y +3 = x -4
Step-by-step explanation:
The line with slope m through point (h, k) can be written in point-slope form as ...
y -k = m(x -h)
For (h, k) = (4, -3) and m=1, the filled-in form is ...
y +3 = x -4
___
It happens that the same line can be described by ...
y +4 = x -3 . . . . . matches the second choice
because that line also goes through the point (3, -4).
Answer:
y is 5 units greater than x
Step-by-step explanation:
This is a Bayes Theorem Problem
P(oil | negative test) P(negative test)= P(negative test | oil) P(oil)
P(oil | negative test) = P(negative test | oil) P(oil) / P(negative test)
P(oil | negative test) =P(negative test | oil) P(oil) / ( P(negative test | oil) P(oil) + P(negative test | no oil) P(no oil) )
We're given the prior probability of oil, P(oil)=.45, so P(no oil)=.55
We given P(negative test | no oil) = 0.80, so P(negative test | oil) = .20
Choice A
Answer:
Shorts = 112 and t shirts = 165
Step-by-step explanation:
Let S = shorts
Let T = t shirts
T + S = 277
$2T + $3S = $656
-2(T + S) = 277 so -2T -2S = -544
2T + 3S = 656 so 2T + 3S = 656
------------------------
SO: (subtract T's cancel out) 1S = 112
divide by 1 so S = 112
Plug S into the top equation: T + s = 277 T + 112 = 277 so T = 165
