Based on geological studies done on land in East Texas, a petroleum compond no oil is 26%. probability of finding high-quality oil is 31%, medium-quality oil is 43%, and soil test (since Since drilling can be expensive, the petroleum company also plans on doing a soil test (sinee certain soil types are more apt to detect the presence and quality of oil). For example, the petroleum company knows that in 13% of high-quality oil finds, 9% of medium-quality oil finds, and 4% of no oil finds, the soil is Type A. So, for this East Texas land dium-quality oil is 43%, and no oil is 26%
1. Find the probability that high-quality oil is found given the soil was not Type A.
2. Find the probability the soil was not Type A or no oil is found.
3. Find the probability oil is found given the soil was Type A.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

answer: y = -2.5x - 15

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
