Answer:
At a 5% significance level we reject the Null hypothesis
Step-by-step explanation:
From the question we are told that:
Distance
Mean
Sample size
Sample mean
Standard deviation
significance level
Generally the Hypothesis is mathematically given by
Generally the equation for t test statistics is mathematically given by
Therefore P-Value from table
Therefore
At a 5% significance level we reject the Null hypothesis
Answer:
5
Step-by-step explanation: rise over run 5/1= 5
Answer:
the time is 1.57 sec and the distance is 49.32mm
Step-by-step explanation:
Given that,
The angle is 180°
Angular velocity is 2rev/sec
The radius is 10mm
we are to find the time and distance traveled at that time
The formula is
θ = at
where t is the time,
a is the angular velocity
θ is angle in radian
so,
θ = 180° × π/180°
θ = π
= 3.14
Hence ,
θ = at
3.14 = 2t
t = 1.57sec
let the distance be xmm
Therefore , the time is 1.57 sec and the distance is 49.32mm
5≤x≤9 it can also be reversed as 9≥x≥5 which is the same thing
