Step-by-step explanation:
(A)
Length of wire = 30.48 m
Area of cross section = 3.22 * 10 ^ -5 m^2
(B) length of wire = 1219.2 m
Area of cross section = 1.29 * 10^-5 m^2
Resistance = 8.45 * 10^-8 * 1219.2 / 1.29 * 10^-5 = 7.98 Ohms
3 x 3,000 umm and 1,000 x 9
Answer:
b. mean: 42, mode: 46
Step-by-step explanation:
if x1,x2,x3,...,xn are n observations then
mean=( x1+x2+...+xn)/n and mode is the element having the highest frequency i.e. element occuring most of the time
mean=(59+16+57+46+58+21+36+41+23+64+20+66+40+51+28+46)/16
=42
46 occurs twice while all other numbers occur only once so, mode=46
