From 15 yards to 18 yards there is an increase of 3.
Answer: increase
To answer the problem, we must identify the terms first. Our minuend is 13a - 5 and our subtrahend is 16a + 3.
minuend - subtrahend = difference
(13a - 5) - (16a + 3) = difference
<em> difference = -3a - 8</em>
The answer to your question would be 54
Answer:
a)20$
b)46,1$
c)0,3336
d)No concerns
Step-by-step explanation:
A) To find expected difference of cost of medical care for dogs and cats we can simply subtract average costs of cats and dogs.
Expected difference will be 20$.
B) To find the standard deviation of that difference, we need to square deviations and add them and square root it again.
Expected difference will be 46,1$.
C)We need to find the Z value to find the probability of more expensive dogs than cats in a Vet vise.
Z value of the function is -0,434
From the Z table that you can find at the attachment. The probability is %33,36 or 0,3336
D) This is a subjective part. I don't have any concerns
