Answer:
dylan has more water
Step-by-step explanation:
1000 milliliters = 1 liter
therefore 600 milliliters = .6 liters
1 - .6 = .4
the liter has .4 more liters of water or 400 more milliliters
The speed upstream is the difference between the boat speed and the current speed. It is (12 mi)/(4 h) = 3 mph.
The speed downstream is the sum of the boat speed and the current speed. It is (32 mph)/(4 h) = 8 mph.
The speed of the boat is the average of these: (3 + 8)/2 = 5.5 mph.
The speed of the current is that less the difference: 5.5 - 3 = 2.5 mph.
_____
<u>Check</u>
Boat + Current = 5.5 + 2.5 = 8 mph
Boat - Current = 5.5 - 2.5 = 3 mph
Step-by-step explanation:
Q9. 5n + 8 = 43
5n = 43 - 8
5n = 35
n = 35/5
n = 7
Q10. y/6 - 7 = 4
y/6 = 4 + 7
y/6 = 11
y = 11×6
y = 66
Q11. 8w - 15 = 57
8w = 57 + 15
8w = 72
w = 72/8
w = 9
Q12. g/3 + 11 = 25
g/3 = 25 - 11
g/3 = 14
g = 14×3
g = 42
Q13. f/5 - 22 = -25
f/5 = -25 + 22
f/5 = -3
f = -3×5
f = -15
Q14. -4p + 19 = 11
4p = 19 - 11
4p = 8
p = 8/4
p= 2
Using the Empirical Rule, it is found that 49 farms in the sample have land and building values per acre between $1100 and $1700.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Considering the given mean and standard deviation, values between $1100 and $1700 are within 1 standard deviation of the mean, which is a percentage of 68%.
Hence, the number of farms out of 72 is:
0.68 x 72 = 49 farms.
