1 answer:
Answer:
The length of the rectangular banner is 10 inches
The width of the rectangular banner is 2 inches .
Step-by-step explanation:
Given as :
The length of rectangular banner is five times as long as its width
The perimeter of rectangular banner = P = 24 inches
Let The width of rectangular banner = w inches
And The length of rectangular banner = 5 w inches
Now, According to question
The perimeter of rectangular banner = perimeter of rectangle = 2 × length + 2 × width
Or, The perimeter of rectangular banner = 2 × 5 w + 2 × w
Or, 24 inches = 10 w + 2 w
Or, 24 inches = 12 w
∴ w =
I.e w = 2 inches
So, The width of rectangular banner = w = 2 inches
Put the value of w to get length
So, The length of rectangular banner = 5 × 2 = 10 inches
Hence The length of the rectangular banner is 10 inches and The width of the rectangular banner is 2 inches . Answer

Step-by-step explanation:
melanin content Total
high low
moisture high 13 10 23
content low 47 30 77
Total 60 40 <u> </u><u>100</u>
Let A denote the event that a sample has low melanin content, and let B denote the event that a sample has high moisture content.
a) Total skin samples has low melanin content = 10+30=40
P(A)=
b) Total skin samples has high moisture content = 13+10=23
P(B) =
c) A ∩ B = Total skin samples has both low melanin content and high moisture content =10
P(A ∩ B) =
