Answer:
C.
Step-by-step explanation:
Simplify the expression
-3y=-x+1; 3y=x-1; y= x/3 -1/3 so the y-intercept is at -1/3
The height of the fifth bounce
80x65%x65%x65%x65%x65%
=9.282325 cm
Something you should know. A ratio is comparing two numbers. Anyway, the ratio is 12:8, remember to put it the order as it is listed. I hope this helps.
Answer:
There are 220 ways by which the medals can be awarded to three of the 15 gymnast, if exactly one of the Americans wins a medal
Step-by-step explanation:
From the question, we have;
The number of gymnast in the Olympic women's competition = 15
The number of the gymnast who are Americans = 4
The number of medals awarded = 3 medals
The number of ways hat the medals can be awarded to the three of the gymnast if exactly one of the Americans wins a medal is given as follows;
The number of ways one of the medals can be won by one of the four Americans = ₄C₁ = 4 ways
The number of ways the other two medals can be won by the remaining 11 gymnast = ₁₁C₂ = 55 ways
Therefore, the total number of ways, 'N', the medals can be awarded to three of the 15 gymnast, if exactly one of the Americans wins a medal is given as follows;
N = ₄C₁ × ₁₁C₂
∴ N = 4 × 55 = 220
