Answer:
Slope =-1/4
Step-by-step explanation:
y=mx+n
Slope=m=(y2-y1)/(x2-x1)
A(-1,19).... x1 =-1, y1=19
B(11,16)..... x2=11, y2=16
Slope=(16-19)/(11-(-1))=(-3)/(11+1)=-3/12=-1/4
Well, split into two parts then multiply the sides and then round it to the nearest tenth.
Answer:
D) Of the 4 people who have a sister, 1 of them also has a brother.
Step-by-step explanation:
P(B/A) indicates the probability of event B when event A has alredy occured.
Event A = The person has a sister.
Event B = The person has a brother.
So now P(B/A) means the probability of the person having sister who already have brother.
Hence choice "D) Of the 4 people who have a sister, 1 of them also has a brother." is correct.
Length (L): 2w + 5
width (w): w
Perimeter (P) = 2L + 2w
136 = 2(2w + 5) + 2(w)
136 = 4w + 10 + 2w
136 = 6w + 10
126 = 6w
21 = w
Length (L): 2w + 5 = 2(21) + 5 = 42 + 5 = 47
Answer: width = 21 meters, length = 47 meters
