Answer:
.7143
Step-by-step explanation:
there are 5 trouts so 5/7
What you have to do is find the slope and the y intercept
The equation is y=-15/6x+14
One is going 52 and the other 64
2 (x)+2 (x+12)=232 and solve
I hope you might have understood.
Answer:
(78, 80)
Step-by-step explanation:
Given a normal distribution :
Mean = 79 seconds
Standard deviation = 0.5 seconds
Using the empirical rule :
95% of her finishing times :
According to the empirical rule, 95% represents 2 standard deviations from the mean that is ± 2 standard deviations from the mean score or value.
Hence ;
The interval will be defined as ;
Mean ± 2(standard deviation)
79 ± 2(0.5)
79 ± 1
(79 - 1) ; (79 + 1)
78 ; 80
