Answer:
0,37
Step-by-step explanation:
It will be easier if we noun the events.
A= Cindi's friend comes to England.
B= New England is mostly cloudly.
We are searching the probability of just A doesn´t happen or just A happens but not B.
The probability of A doesn´t happen is one minus the probability of A:
The events A and B are independent for this reason the probability than both occurs is the product of the probability of each event. It means:
The probability of A doesn´t happen or A and B happen is:
Conclusively we have to rest the probability of A doesn´t happen and A and B happen, but A happens and doesn´t happen and the same time is impossible. For this reason, we have the same result.
Then the probability either Cindi's friend does not come to New England, or she does come but it is mostly cloudy is 0.37
X-6 = X+10 i believe that should be the equation
110.10 +4x = 150.10
4x=40
x=10 :D
Answer
P= 2L+2W
P=2(12) +2(7) =38
Step-by-step explanation:
The width of a rectangle is 5 meters less than its length. The area is 84 square meters. Find the dimensions of the rectangle and the perimeter of the rectangle.
First it helps to draw a picture so draw a rectangle
Remember that area of a rectangle =Length times width and the perimeter is P= 2 times the length plus 2 times the width
So A=LW and P=2L+2W
84= area
L=length
W= length -5
L(L-5)=84 distribute the L and you have L2 -5L=84 now subtract 84 from both sides and get L2 �5L-84 next factor to get (L+7)(L-12) next set both to =0 (L+7)=0 (L+12)=0 solve for L
L=-7 and L=12 you can�t have a negative length so -7 is out. So L=12 now plug in to the original area equation
84=LW 84= 12w now divide both sides by 12 to isolate W, this gives you W=7
L=12 and W= 7
For perimeter use 12 for the length and 7 for width Remember that P= 2L+2W
P=2(12) +2(7) =38
