Answer:
40 ¢
0Step-by-step explanation: 25 + 10 + 5 = 40
Distribute on the left
217+111x-185=-4
Combine like terms
111x+32=-4
Sybtract 32 from both sides
111x=-36
Divide both sides by 111
x= -36/111
x=-12/37
Final answer: x=-12/37
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%.
To solve for x, simply rearrange the problem:

The answer is D.
