A certain data scientist is testing his predictor (essentially a tool given historical data and would make predictions using sai

d data) that would make predictions about Philadelphia’s temperatures. The predictor produces a correct temperature if the prediction falls within three standard deviations from the target value. Assume that the expected value of each prediction equals the target value.
What is the accuracy of the predictor if the distribution of measurements is uniform?

Answer:

x= 60°, y = 80°, z = 40°

Step-by-step explanation:

Look at the line substending 40° and Z°; you would see that both lines are parallel and so their angles are they the same.

Hence z= 40° { corresponding angles of parallel lines}

Similarly;

Look at the line substending 60° and x°; you would see that both lines are parallel and so their angles are they the same.

60° = x° { corresponding angles of parallel lines}

Now looking at the angle between x and y; let's call the angle between them r

And you would observe closely that r = z° = 40°{ vertically opposite angles are equal}

Note that x + r + y = 180°{ angle on a straight line}

y = 180° - ( x + r)

y = 180 - (60+40)

y = 180° - 100°

= 80°

40 ÷ 200 = 0.2

→ Multiply the answer by 100

0.2 × 100 = 20%
