Answer:
honestly i think its 2f=9x
Step-by-step explanation:
might not be 2f=9x but make sure to chexk your answer
Answer:
I'm pretty sure you have to do slope intercept form so it would be like this.
Y= mx+b
M is 1/2 and the X is given in the ordered pairs. Y is also given but it counts as the intercept so it is actually the 'B' of the equation. YOu just have to fill it in.
Y= 1/2(-4) + 2
Answer: D) how close a measured value is to the actual value.
Step-by-step explanation: Accuracy is simply a measurement metric which is used to establish how a measured or predicted value conforms to the actual measurement usually in terms of closeness. Accuracy is different from precision which measures closeness in values obtained from repeated measurement of the same sample. For instance;
If the actual vale of a measurement is : 11.34
Prediction 1 : 11.30
Prediction 2 : 11.32 ;
Prediction 2 will be said to be more accurate than prediction 1 becuase it is closer to the actual value than prediction 1.

Answer:
Step-by-step explanation:
The tangent of the angle can be found using the identity for the tangent of the difference of angles.
tan(α-β) = (tan(α) -tan(β))/(1 +tan(α)tan(β))
The tangent of the angle of each vector is the ratio of the j coefficient to the i coefficient.
tan(α) = -2/3
tan(β) = 4/7
tan(α-β) = (-2/3 -4/7)/(1 +(-2/3)(4/7))
= (-14-12)/(21 -8) = -26/13 = -2
Then the magnitude of the angle between the vectors is ...
arctan(2) ≈ 63.43°
