Answer:
Total number of 1 2/3 feet long pieces that will be cut=8 pieces
Step-by-step explanation:
This can be expressed as;
Total length of the board=length per piece×number of pieces
where;
Total length of board=14 1/4 feet
Length per piece=1 2/3 feet
Number of pieces=n
Replacing;
14 1/4=1 2/3×n
(57/4)=(5/3)n
n=(57/4)×(3/5)=8.55
Total number of 1 2/3 feet long pieces that will be cut=8 pieces
25*8.14=?
Multiply the cost of the book per person ($8.14) by the number of people (25).
Answer:
Mary can read one page per two minutes.
Step-by-step explanation:
20 divided by 10 equals two
2(x+1)+3x=37
simplifythe left side:
2x +2 +3x = 37
Combine like terms:
5x +2 = 37
Subtract 2 from both sides:
5x = 35
Divide both sides by 5:
x = 7
Answer: a. 0.40 b. 0.23 c . 0.435 d . 0.25
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) =
Using conditional probability formula , 
d)
