part a- x + 3.25 x + 3.25 3x - 2 3x - 2 3x - 2
part b- 21x
part c- 7.75
Answer:
The probability is 0.003
Step-by-step explanation:
We know that the average 
is:
The standard deviation 
is:
The Z-score is:
We seek to find
For P(x>800) The Z-score is:
The score of Z = 3 means that 800 is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15%
So
For P(x<200) The Z-score is:
The score of Z = -3 means that 200 is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15%
So
Therefore
Answer:
9
Step-by-step explanation:
9x2 is 18, so he can rent a bike for nine days if the rent is $2
You would beee to do 20/0.8 which would give you 25 water stations in total.
Hope that helped
Answer:
B. 2 + (3^2 * 5) - 3
Step-by-step explanation:
Hey! Sorry for the long wait, I'm still in school and can't really be here 24/7 but I'm proud to announce that I have your answer!
So we have 4 expressions and we need to get our answer to 44. This question already includes the notion that parenthesis placements make a huge difference, so let's review them.
<h2>A.</h2>
2 + 3^2 * (5 - 3)
Use PEMDAS
2 + 3^2 * 2
2 + 9 * 2
2 + 18
20
<h2>B.</h2>
2 + (3^2 * 5) - 3
2 + (9 * 5) - 3
2 + 45 - 3
47 - 3
44
<h2>C.</h2>
(2 + 3^2) * 5 - 3
(2 + 9) * 5 - 3
11 * 5 - 3
55 - 3
52
<h2>D.</h2>
(2 + 3)^2 * 5 - 3
(5)^2 * 5 - 3
25 * 5 - 3
125 - 3
122
As we can see, B. is our answer due to its equivlance to 44.
