Answer: x = 7
Explanation:
Subtract 8 from both sides to isolate x.
x + 8 = 15
x + 8 -8 = 15 - 8
x = 15 - 8
x = 7
9x-9y=-9
x-y=-9/9
x-y+1=0.......(1)
4x-3y=-8
4x-3y+8=0....(2)
combining equation we get
(x-y+1)(4x-3y+8)=0
x(4x-3y+8)-y(4x-3y+8)+4x-3y+8=0
4x²-3xy+8x-4xy+3y²-8y+4x-3y+8=0
<u>4x²+3y²-7xy+12x-11y+8=0</u><u> </u><u>is</u><u> </u><u>your</u><u> </u><u>equation</u><u>.</u>
Answer:
(C) A model with 21% training error, 21% validation error, and 75% sensitivity.
Step-by-step explanation:
In best classification models training error is equal to validation error, therefore A model with 21% training error, 21% validation error, and 75% sensitivity is most likely to be the best when applied to the test sample.
Pythagorean theorem: a^2 + b^2 = c^2
The hypotenuse is always the c in the equation.
If the two side lengths they gave you are not the hypotenuse, then enter
4.5^2 + 5.6^2 in the calculator, then find the square root of that. :-)
The union of the two sets is the combining of the two sets, so the correct answer is A. {4, 8, 10, 12, 14}.
Hope this helps =)
