Answer:
5 miles
Step-by-step explanation:
An hour and 25 minutes is 85 minutes. Using the given information we can find the distance d with the proportion ...
In 1 hour and 25 minutes, Nick will travel 5 miles.
Empirical rule dictates that, in a Bell-shaped distribution, 95% of data lies within 2 standard deviation on either side of the mean.
Therefore,
Lower value = mean-2SD = 70-2*8 = 70-16 = 54
Upper value = mean+2SD = 70+2*8 = 70+16 = 86
Then, 95% of the data lies between $54 and 84. These values can also be taken as the true mean of the population considering 95% confidence when sample mean has been calculated. In this regard, 2SD can be regarded as the margin error.
P=18 because 3 times two is 6 and 4 times 3 is 12 so when you add them you get 18
Answer:
do it yourself
Step-by-step explanation:
(h+g)(x) = 3x + 5 + 6x = 9x + 5Answer
(h - g)(x) = 6x - (3x + 5) = 3x- 5 Answer
(h*g)(x) = 6x(3x + 5) = 18x^2 + 30x
(h*g)(2) = 18(4) + 30(2) = 72 + 60 = 132 Answer
