Answer:
x and y = 0
the question looks weird and almost wrong because when you subtract the equations, you are left with nothing
Step-by-step explanation:
Multiply the top equation by 3 to make the -x a -3x instead.
Then do the top equation - the bottom equation
At this point you should be left with x
Answer:
1/2
Step-by-step explanation:
Step one:
given data
sample space
1 blue slice,
2 red slices, and
3 yellow slices
sample size= 1+2+3= 6
Required:
The probability that the dial stops on a blue or red slice
1. The probability that the dial stops on a blue = 1/6
2. The probability that the dial stops on a red= 2/6= 1/3
Hence The probability that the dial stops on a blue or red= 1/6+1/3
= 1+2/6
=3/6
=1/2
1/4 is .25 so
.25/3 is 0.0833333...
Answer:
Total length of the first swing=64 m
Step-by-step explanation:
The total length of all four swings can be expressed as;
Total length of all 4 swings=Length of first swing+length of second swing+length of third swing+length of fourth swing
where;
Total length of all 4 swings=175 m
Length of first swing=x
Length of second swing=75% of length of first swing=(75/100)×x=0.75 x
Length of third swing=75% of length of second swing
Length of third swing=(75/100)×0.75 x=0.5625 x
Length of fourth swing=75% of length of third swing
Length of fourth swing=(75/100)×0.5625 x=0.421875 x
replacing;
Total length of all 4 swings
175=x+0.75 x+0.5625 x+0.421875 x
2.734375 x=175
x=175/2.734375
x=64
Total length of the first swing=x=64 m
