The scale is determined by dividing the respective measures of the two paintings.


Original painting           mural       scale factor

3                                    15            original / mural = 3 / 15 = 1 / 5

2                                    10            original  / mural = 2 / 10 = 1 / 5

As you see the scale to comparing the original to the mural es   1 feet : 5 feet.  

It  means that the measures of the original painting must be multiplied by 5 to obtain the measures of the mural.

Suppose a baseball team has 14 players on the roster who are not members of the pitching staff. Of those 14 players, assume that
Nadusha1986 [10]

Answer: Our required probability would be 0.70.

Step-by-step explanation:

Since we have given that

Number of players = 14

Number of players have recently taken a performance enhancing drug = 3

Number of players have not recently taken a performance enhancing drug = 14-3=11

Number of members chosen randomly = 5

We need to find the probability that at least one of the tested players is found to have taken a performance enhancing drug.

P(Atleast 1) = 1 - P(none is found to have taken a performance enhancing drug)

So, P(X≥1)=1-P(X=0)

P(X\geq 1)=1-^5C_0(\dfrac{11}{14})^5\\\\P(X\geq 1)=1-(0.786)^5\\\\P(X\geq 1)=0.70

Hence, our required probability would be 0.70.
