Otis measured the heights of several sunflowers. He found that their heights were 2,3,5,7, and 8 feet.
Otis found that the mean was 5 feet and the range was 6
feet.
Which numbers describe the center and spread of this data set?
A. 8 feet describes the center, and 2 feet describes the spread.
B. 6 feet describes the center, and 5 feet describes the spread.
C. 2 feet describes the center, and 8 feet describes the spread.
D. 5 feet describes the center, and 6 feet describes the spread.

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

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

i have no idea just need points sorry
