In logging data with a high sampling rate, the calculated standard deviation of large number of readings are 4.00 V, 1.00 A, and 0.02 for the power factor, while the mean values are 480 V, 50.0 A, and a power factor of 0.83. Determine the random uncertainty of the measurements, at a 95% confidence level.

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
