Answer:
The probability that a car driver can complete the transaction in less than 5 minutes is 0.4647.
Step-by-step explanation:
Let <em>X</em> = times required by drivers to fill their car's tank and pay.
The average time required by drivers is, <em>β</em> = 8 minutes.
The random variable <em>X</em> is Exponentially distributed with parameter,
.
The probability distribution function of exponential distribution is:

Compute the probability that a car driver can complete the transaction in less than 5 minutes as follows:

Thus, the probability that a car driver can complete the transaction in less than 5 minutes is 0.4647.
<u>the slope would be 7</u> once you added 3y to both sides, and then subtracted the 15 from both sides and then divided all terms by 3
If you mean the calculation of 77x11 then the answer is 847
Answer:
16 square inches.
Step-by-step explanation:
Split the shape into a rectangle and square. To solve for square, just mulitple the 2 sides (2 x 2) and you get an area of 4. To solve for the rectangle, you can multiple the 6 and 2 to get the area of 12. Add the 4 and 12 together and you get 16 square inches. Hope this helps!
