Matrix a below gives the fraction of the earth's area and the projected fraction of its population for five continents in 2050. matrix b gives the earth's area (in square miles) and its projected 2050 population.† fraction of area fraction of population 0.162 0.047 north america 0.119 0.086 south america a = 0.066 0.065 europe 0.298 0.582 asia 0.202 0.215 africa area population b = 57,850,000 0 area 0 9,322,000,000 population find the area (in square miles) and population of each given continent by finding ab.

  see below

Step-by-step explanation:

In order to get a 5×2 matrix result from the multiplication of AB, the dimensions of matrix B must be 2×2. The given numbers can be put on the diagonal of that matrix to achieve the desired effect.

You want ...

The rows are in the order given in the problem statement: North America, South America, Europe, Asia, Africa. The left column is area; the right column is population. Here, numbers have been rounded to 3 significant figures. The multipliers are consistently millions and billions to make comparison easier.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

answer: the answer is b. i think hope i got it correct
