The z-score associated with 14.3 is 0.84. 0.2995 of the population is between 12.2 and 14.3. 0.1894 of the population is less than 10.0.
The formula for a z-score is
z=(X-μ)/σ
With our data, we have:
z=(14.3-12.2)/2.5=0.84
The z-score associated with the mean is 0.5. To find the proportion of the population between the mean and 14.3, subtract 0.7995 (the proportion of population below the z-score of 0.84, using http://www.z-table.com) and 0.5:
0.7995 - 0.5 = 0.2995.
The z-score for 10.0 is
(10.0-12.2)/2.5 = -0.88. The proportion of the population less than this is 0.1894.
The best estimate for the length of a car is about 13-15 feet wide.
Answer:
(x+9)^2+(y+5)^2=81
Step-by-step explanation:
(x-h)^2+(y-k)^2=r^2
(h,k)=center
r=radius
so if you just insert the center (-9,-5) and the r with 9
(x-(-9))^2+(y-(-5))^2=9^2
(x+9)^2+(y+5)^2=81
Hope that helps :)
Answer:
Step-by-step explanation:
Let
h-------> the minimum height for riding on the Super Screaming Spinner at the theme park
we know that
the height may not be less than 
so
-------> inequality that represent the situation
6 pints is greater than 60 fluid ounces because 6 fluid ounces is equal to 96 fl.
