Can you tell me what do you mean exactly by menu of 8, so i can help you.
Step-by-step explanation:
anyway, without any further information about ground consistency, friction and stuff, we have to assume ideal circumstances.
so, the same energy that made the ball flying through the air makes it also bounce or roll across the ground carrying it exactly the same distance at the same time.
the distances with an ideal, reflective ground will be the same.
it is the same energy released with the same inertia.
Answer:
x-intercept = .5 y-intercept = 1
Step-by-step explanation:
the x-axis is crossed at .5 and the y-axis is crossed at 1.
Answer: Yes, this sample provide evidence that people living in rural communities live longer than 77 years.
Step-by-step explanation:
Since we have given that
Average lifespan in the USA = 77 years
We need to check whether the people living in rural communities live longer than 77 years.
So, Hypothesis would be
Since n = 12
since n <30 so, we will use t test.
So, the test statistic value is given by
degrees of freedom = df = n-1 = 12-1 =11
At 95% significance level , t = 1.796
Since, 1.796< 9.125
So, we will reject the null hypothesis.
Hence, Yes, this sample provide evidence that people living in rural communities live longer than 77 years.
