Answer:
Hello,
<u>P(B)=0.65</u>
Step-by-step explanation:
If P(A+B) means P(A∪B)=0.93 then you may read below.
Let's say x=P(B)
A and B being independent, P(A∩B)=P(A)*P(B)=0.8*x
Since P(A∪B)=P(A)+P(x)-P(A∩B) ,
0.93=0.8+x-0.8*x
0.2*x=0.13
x=0.65
Answer:
108
Step-by-step explanation:
To find x, you need the geometric mean. First, find the second part of 225 by doing 225 - 144 = 81. Now, to find geometric mean, do 81 x 144 = 11,664; 
.
Answer:
Step-by-step explanation:
![\displaystyle \sqrt[3]{-\frac{1}{125} }](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Csqrt%5B3%5D%7B-%5Cfrac%7B1%7D%7B125%7D%20%7D)
Distribute the cube root to the numerator and denominator.
![\displaystyle -\frac{\sqrt[3]{1} }{\sqrt[3]{125} }](https://tex.z-dn.net/?f=%5Cdisplaystyle%20-%5Cfrac%7B%5Csqrt%5B3%5D%7B1%7D%20%7D%7B%5Csqrt%5B3%5D%7B125%7D%20%7D)
Solve for the cube root.
Answer:
2/5 pound
Step-by-step explanation:
The first bag is 1/5 pound more than 3 pounds. The second bag is 1/5 pound less. The difference in weight is 1/5 +1/5 = 2/5 pounds.
If you'd like to see that as an equation, you could write ...
Δw = (3 +1/5) -(3 -1/5)
= (3 -3) +(1/5 -(-1/5))
= 0 +1/5 +1/5 = 2/5
The weight difference is 2/5 pounds.
