Answer:
Fraction of the scouts are square dancing is 
.
Step-by-step explanation:
Each pair is one Girl Scout and one Boy Scout.
So, to the final fraction ( of the pairs) we are going to get 1/2 from the fraction of girls and 1/2 from the fraction of boys.
Girls= 
Boys= 
To get the fraction of the scouts that are square dancing, we have to add the fraction of girls , with the fraction of boys.
=
=
=
=
This means that from 30 scouts , 19 are dancing.
Answer:
Yes, distance in yards can be obtained by multiplication.
Step-by-step explanation:
Given that the distance between tow points is 90 feets, The distance between these two points in yards can be obtained either by multiplication or division.
I foot = 0.3333 yards
To convert distance between the second and third bases from feet to yard ;
Multiply distance in feets by 0.3333 to obtain the corresponding distance in yards ;
90 * 0.3333 = 29.997 = 30 yards
Prob (first defective) = 4 / 20 = 1/5
Prob(2nd defective) = 3/19
Prob (3rd defective) = 2/18 = 1/9
Pron 4th defective) = 1/ 17
Prob ( all 4 defective) = 1/5 * 3/19 * 1/9 * 1/17 = 1 / 4845 answer
Yes. The 100 - 85 = 15, meaning 15% of parents said yes. 85 > 15
