Solution: The regression equation is:
Where x is the number of years since it opened in 2003.
We have to find the cost of a vehicle to drive through the safari in 2008.
Therefore using the given equation, we have:
Therefore, the best estimate for the cost of a vehicle to drive through the safari in 2008 is $8.42.
Hence the option C.$8.42 is correct
Step-by-step explanation:
so the first thing you need to do is open the brackets, so 3 times( b-4) equals to 3b-12. so until here very easy already. then just move all your number to the right except the variables. so like this you may get your answer
Answer:
Length-25
Width-9
Step-by-step explanation:
x-width
2x+7-height
6x+14=68
-14 -14
6x=54
x=9
Answer:
Step-by-step explanation:
The question is incomplete. The complete question is:
Based on data collected by the National Center for Health Statistics and made available to the public in the Sample Adult database (A-5). an estimate of the percentage of adults who have at some point in their life been told they have hypertension is 23.53 percent. If we select a simple random sample of 20 U.S. adults and assume that the probability that each has been told that he or she has hypertension is .24. find the probability that the number of people in the sample who have been told that hypertension will be: a) Exactly three (b) Three or more (c) Fewer than three (d) Between three and seven, inclusive
Solution:
This is a binomial probability distribution. If an adult is selected randomly, the outcome is either he has been told that he has hypertension or he has not been told. The probability of success, p would be that a randomly selected adult, x has been told. Therefore,
p = 0.24
n = 20
a)We want to determine P(x = 3). From the binomial probability distribution calculator,
P(x = 3) = 0.15
b) P(x ≥ 3) = 0.89
c) P(x < 3) = 0.11
d) P(3 ≤ x ≤ 7)
It would be P(x ≤ 7) - P(x ≥ 3)
P(x ≤ 7) = 0.92
Therefore,
P(3 ≤ x ≤ 7) = 0.92 - 0.89 = 0.03
It may be misleading because it only tells you those two years, not what happened between those years
