An oil company purchased an option on land in Alaska. Preliminary geological studies showed that there is a 66% chance that there is oil under the land. After 200 feet of drilling on the first well, a soil test is made and soil type XT2 is found. Such soil is found 84% of the time when oil is present and only 37% of the time when oil is not present. Given that soil type XT2 was found, what would your new assessment of the chance that oil is present be

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7

step-by-step explanation:

because i took test

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

if the probability is 1/12, 75 people will receive a $25 gift card
