Answer:
Rayshawn originally had $30.
Step-by-step explanation:
i) Rayshawn has a certain amount of money. Let us say this amount is $x.
ii) Rayshawn spends $20 which means that he is left with $(x - 20)
iii) it is also given that amount of money left after spending $20 is 
of the original amount, $x, the amount remaining is 
.
iv) from the information given in ii) and iii) we get
$(x - 20) = , Therefore we get 3x - 60 = x , therefore 2x = 60,
Therefore x = $30. Rayshawn originally had $30.
Answer:
Step-by-step explanation:
we have to divide the given distance by 3.
Then we will be able to find the distance between markers.
Given distance is
Since, there are three markers,
So, we have to divide this distance by 3
So, the distance between markers is-
So, the distance between marker is
Now, we have to convert this into mixed number.
Then, the distance is-
Answer:
The probability that the cost for someone's dog is higher than for the cat is 33.2%.
Step-by-step explanation:
With the data given, we know that the difference in cost of medical care of dogs and cats have a normal distribution with μ=-20 and σ=46.
To know the probability of the cost for the dog is higher than the cat, we have to calculate the probability of P(d>0).
Then we have to calculate z, and look up in a standarized normal distribution table.
Calculate z:
The probability of the difference being higher than 0, we have:
We can say that the probability that the cost for someone's dog is higher than for the cat is 33.2%.

The second quadrant is the quadrant in the top left when looking at a graph. If the figure were to be reflected across the y-axis (the vertical axis), then that figure would end up in the top right quadrant, which is the first quadrant. :)
