Answer:
P(A or B) = P(A) + P(B) - P(A and B) = 0.5 + 0.7 - 0.3 = 0.9
Step-by-step explanation:
The equation we should use to calculate the addition of probabilities is:
P(A or B) = P(A) + P(B) - P(A and B)
Notice that if we just sum P(A) + P(B), our result would be wrong, because we would sum the intersection of those events two times.
So, in this case, if we call 'A' the pillow being encased in microfiber and 'B' the pillow being filled with memory foam, we have that:
P(A) = 0.5
P(B) = 0.7
P(A and B) = 0.3
So the addition of both probabilities is:
P(A or B) = 0.5 + 0.7 - 0.3 = 0.9
FORMULA: AREA = LENGTH X WIDTH
with this we can proceed so the area is 20
the length is 40 inches and
answer is : width ----18.94---
10.041 is standard form and I don't know the expanded form
We have been given that Khalil has 13.5 M of lanyard. He needs to cut the lanyards into pieces that are 90 cm long. We are asked to find the number of full-length pieces of a lanyard will Khalil be able to cut.
First of all, we will convert 13.5 meter into cm.
1 meter = 100 cm
13.5 meters = 13.5*100 = 1350 cm.
Now we will divide 1350 by 90 to find number of pieces of lanyard that can be cut from 1350 cm.


Therefore, Khalil will be able to cut 15 full-length pieces of a lanyard.
The answer is : (3x-1)(x+4)
