Answer:
Step-by-step explanation:
%change=100(final-initial)/(initial)
%change=100(26-20)/20
%change=30%
Since this is positive the number of dogs increased by 30%
Answer:
See the attached picture for answer.
Step-by-step explanation:
According to a center for disease control. We can’t compute the probability.
<u>SOLUTION:
</u>
Given that, According to a center for disease control,
The probability that a randomly selected person has hearing problems is 0.157.
The probability that a randomly selected person has vision problems is 0.096.
We have to find whether we can compute the probability of randomly selecting a person who has hearing problems or vision problems by adding these probabilities or not?
The answer is no, because hearing and vision problems are not mutually exclusive.
So, some people have both hearing and vision problems.
These people would be included twice in the probability.
Hence, we can’t compute the probability.
Answer: f(x) = 3(0.7)^x
Because as the exponent (x) of 0.7 grows the result decreases. When x is a big negative number the decay is fast, when the x is a big positive number the decay is low, and the function appraches assymptotically to a constant value. This is the behavior of an exponentially decaying function.

Answer:</h2><h2>
The probability that Roy gives randomly an SUV = 15 / 47</h2>
Step-by-step explanation:
The total number of used cars owned by Roy = 47
[12 trucks + 20 cars + 15 SUV = 47 cars]
The total number in sample space, n (S) = 47
The probability that Roy is giving away and SUV = ?
Let A be the event that Roy is giving an SUV
Total no of SUV's , n (A) = 15
The probability of giving an SUV, P (A) = n (A) / n (S)
P (A) = 15 / 47
