An organization wants to find a random sample of voters to predict the winner of a town election. Select all sampling methods that generate a random sample.
A. All voters whose age is above 25.
B. 100 voters randomly chosen from a list of all voters in the town.
C. The first 100 voters in line on election day.
D. All voters that must vote using an absentee ballot.
E. A computer-generated list of 100 voters from a database containing all voters in the town.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%

answer: $13,622.84
