Answer:
The best prediction for the number of times a 4 will be drawn from the pile is:
125
Step-by-step explanation:
It is given that:
A set of cards contains cards numbered 1 – 8.
So, the theoretical probability that 4 comes up is:
Ratio of Number of favorable outcome( outcome of 4) to the total umber outcome(i.e. 8 )
Hence, Theoretical Probability that 4 is drawn=1/8
Now, out of 1000 trials the best prediction of number of times 4 is drawn is:
(The probability of drawing 4)×(Number of experiments or trials)
=(1/8)×1000
=125
Root 16²+47² = 49.648 ≈ 50
and since 117 > 50
the answer is A.Obtuse
Answer:
y=1
Step-by-step explanation:
we know that the equation of the line is:
y=mx+b
m= slope= (y2-y1)/(x2-x1)
we have two points giver from the graph:
point 1: (-4,1)
point 2: (2,1)
we to find the slope:
m=(1-1)/(2-(-4))
so we have m=0
we need to find "b"
using the point (2,1)
we have:
1=0x+b
so we have b=1
finally we have
y=0x+1
so y =1
