Answer:
Step-by-step explanation:
LHS a - b = -9 - (-6) = -9 +6 = -3
RHS b-a = -6 - (- 9) = -6 +9 = 3
as LHS not equal to RHS
a-b not equal to b-a
Thus proven
Answer:
And we can find the probability with this difference
And using the normal standard distribution or excel we got:
Step-by-step explanation:
Let X the random variable that represent the soft drink machine outputs of a population, and for this case we know the distribution for X is given by:
Where 
and 
We want to find this probability:
The z score is given by:
Using this formula we got:
And we can find the probability with this difference
And using the normal standard distribution or excel we got:
The first step is finding the height of the cake. The formula for the volume of a box: Volume= length x width x height. So given the volume and length and width: 100= 9 x 11 x h. 100=99h and solve for h. h= 1.01 inches so the batter is more than one inch thick. That means that the matter needs to be baked at 350 degrees Fahrenheit. The formula to convert from Fahrenheit to Celsius: T(C)= (T(F)-32) x (5/9). So (350-32) x (5/9) = 176.667. Rounded to the nearest whole number is 177 degrees celsius.

Find find the area of the closet and subtract it from the area of the (gym and closet)
Area of gym and closet = L x w = 5 x 4 = 20
Area of the closet = L x w = 2 x 1 = 2
Area of gym only = (gym and closet) - closet
= 20 - 2
= 18
Answer: 18 cm²
