Answer:
D. No, Jacob is not correct. The median amount he makes is $84.00 in a day.
Step-by-step explanation:
In this case, the mean is not the best measure of this data.
We can see that there is one value lower than the rest, $58. This brings the mean down.
With the value of $58, the mean is $80.70. If we were to take this value out, the mean would be $85.20, which is higher.
Since the mean is brought down by this value, we should use the median. The median of this data set is $84.
1700000/10 is 170000
So the size of Florida is 170,000
Answer:
a. N(500, 100)
Step-by-step explanation:
The normal probability distribution, with mean M and standard deviation S, can be represented in the following notation.
N(M,S).
In this problem, we have that:
Mean = 500
Standard deviation = 100
Which of the following options would be the correct way to represent the information?
a. N(500, 100)
Answer:
See below
Step-by-step explanation:
From noon to 1500 is three hours
train A then travels <u> 3x</u> where x = speed in km/hr
train B only travels for 2.45 hours and covers
<u> 2.45 ( x + 15) </u> where x + 15 is its speed in km/hr
these two values sum to the 300 km distance
3x + 2.45 ( x + 15) = 300
3x + 2.45 x + 36.75 = 300
x = 48.3 km/hr x+15= 63.3 km / hr
