Answer:
-121
Step-by-step explanation:
-11² = -1 × 11² = -1 × 121 = -121
This is true
Irrational numbers are decimal numbers that have no ending such as Pi. Therefore, such numbers are not whole and cannot be whole.
Answer:
Step-by-step explanation:
Given
Solving (a):
Find k
To solve for k, we use the definition of joint probability function:
Where
Substitute values for the interval of x and y respectively
So, we have:
Isolate k
Integrate y, leave x:
Substitute 0 and x/2 for y
Integrate x
Substitute 0 and 2 for x
Solving (b):
We have:
Where
To find , we use:
So, we have:
Integrate x leave y
Substitute 0 and y/3 for x
Integrate
Substitute 0 and 2 for y
Answer:
The unit rate is about $12per fluid ounce
GP = 1/2 , 1/4 , 1/8 , 1/16
1st) the common ratio is (1/4 : 1/2 ) = 1/2, so r =1/2
2nd) the sum of a GP is:
S= a(1-rⁿ)/(1-r)
S=(1/2).[1-(1/2)⁴]/(1-1/2) = 15/16
