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 !
Answer: the number is -14
Step-by-step explanation: let the number be x
2(x+4) = x-6
2x+8 = x-6
2x-x = -6-8
x = -14
So to solve this you simply have to solve 3.4 x 3.
Multiply the decimal and you get 1.2, multiply the whole numbers and you get 9. 9 + 1.2 = 10.2 or 10 1/5 cups, hope this helps!
Answer:
28 ways to fill the 2 positions
Step-by-step explanation:
There are 8 people who can fill the first position and then there are 7 people who can fill the second position (since the first position is filled)
8 * 7 = 56
But order does not matter, so we divide by the number of positions
56/2 =28
