Answer:
The probability model is
= P(A or B)
Step-by-step explanation:
a) Data and Calculations:
Estimated revenue if the day is sunny = $3,000
Estimated loss if the day is rainy = $600
The probability of rain = 30%
Therefore, the probability of sunshine = 70% (100 - 30)
The probability model is based on the probability of rain or sunshine
= P(A or B)
= A*70% - B*30%
The outcome from either rain or sunshine
= ($3,000 * 70%) -($600 * 30%)
= $2,100 - $180
= $1,920
Answer:
Step-by-step explanation:
We want to find the inverse of
We interchange x and y.
We need to solve for y, so let us multiply through by 2.
Subtract 6 from both sides.
Therefore the required inverse is
AB being the longest and is opposite the right angle.
Answer (B)
