x-axis denotes time in minutes and y-axis denotes distance (in blocks) away from the house.

He left home at zero time, so he started at origin (0,0).

He went to store which is at 6 blocks away from home, he walked at a speed of 3 blocks every 4 minutes. So he walked for 8 minutes to cover 6 blocks distance from home. It means the store is at (8,6). So its graph would be a straight line going from (0,0) to (8,6).

Then he stopped and went into the store for 5 minutes. He stayed at store from point (8,6) to (13,6). Its graph would be horizontal line from (8,6) to (13,6).

Then he went back to home at speed of 2 blocks every 3 minutes, so he walked for 9 minutes to cover 6 blocks distance back to home. It means he returned home at (22,0). So its graph would be a straight line going from (13,6) to (22,0).

The graph is attached herewith the solution.

Suppose that on the average, 7 students enrolled in a small liberal arts college have their automobiles stolen during the semest
strojnjashka [21]

Answer:0.9991

Step-by-step explanation:

The Poisson distribution probability formula is given by :-

P(X=x)=\dfrac{e^{-\lambda}\lambda^x}{x!}, where \lambda is the mean of the distribution and x is the number of success

Given : \lambda=7

The probability that more than 1 student will have his automobile stolen during the current semester is given by :-

P(x\geq1)=1-P(x=0)=1-(\dfrac{e^{-7}7^0}{0!})\\\\=1-e^{-7}=0.99908811\approx0.9991

Hence, the  probability that more than 1 student will have his automobile stolen during the current semester =0.9991

Which mathematical equation represents the solution for k in the equation h + 3 = jk + 6k ?
Tomtit [17]

Answer:

The answer is<u> D.</u> h+3/j+6.

Step-by-step explanation:

Given:

The equation h + 3 = jk + 6k.

Now, to get the mathematical expression.

h + 3 = jk + 6k

So, taking k common on R.H.S we get:

h + 3 = k(j + 6)

Then, dividing both sides by j+6  we get:

\frac{h+3}{j+6} =k

Thus,

k=\frac{h+3}{j+6}

Therefore, the answer is D. h+3/j+6.
