What percent of college graduates and what percent of the non-college graduates in this sample support drilling for oil and natural gas off the Coast of California

Step-by-step explanation:

The table that shows the data distribution has been attached

Required

Determine the percentage in each category that support drilling

From the attachment, there are 438 college graduates and 154 support drilling.

The percentage is then calculated as:

-- approximated

From the attachment, there are 389 non college graduates and 132 support drilling.

The percentage is then calculated as:

-- approximated

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
