Answer:
range=u ± 3.09 sd
Step-by-step explanation:
Given:
mean, u= 26.8 mpg
standard deviation, sd=72 mpg
% contained in interval = 99.8%
the interval for 99.8% of the values of a normal distribution is given by
mean ± 3.09 standard deviation= u ± 3.09 sd
=26.8 ± 3.09(72)
=26.8 ± 222.48
= 249.28 , -195.68
range=u ± 3.09 sd = 249.28 , -195.68 !
The last number line is the correct answer.
Remember PEMDAS.
P=parenthesis
E=exponents
M=multiplication
D=division
A=addition
S=subtraction
Answer:
D) -cos(x)
Step-by-step explanation:
360in^3
The equation of the cone is just the cylinder equation divided by 3, so I order to get the volume of the cylinder you do the opposite: multiply by 3!
So 120 x 3 = 360 :)
