Mark stands at an intersection and observes if cars go left, right, or straight. After watching for a while, he
recorded that 10 cars went straight, 4 cars went left and
6 went right. Estimate the probability that the next car
goes left.

tube or goog would be a great resource to with that question

it’s the first one your welcome

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
