Answer:
The value of the test statistic is 
Step-by-step explanation:
The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the sample mean, 
is the null hypothesis value, 
is the standard deviation and n is the size of the sample.
In this problem:
So
The value of the test statistic is
64 hours per hour average
350 miles ÷5.25 hours in which it took= 63.63 rounded is 64 mph average
Answer:
C. (-13, -7)
Step-by-step explanation:
The location of a point O(x, y) that divides a line AB with location A
and B
in the ratio m:n is given by:
Therefore the coordinates of point X That divides line segment from Y(-8, 8) to T(-15, -13) in the ratio 5:2 is:
Therefore the coordinates of point X is at (-13, -7)
Answer:
you need help to progress cozy im guessing?
Step-by-step explanation:
Given that we know the diameter and gather we know pipe 3.14, we can use the formula C = pi*D where d is the diameter and C is circumference of the circle. Plug in what we know for the variables and then solve.
C = 3.14*12
C = 37.68
Rounding our answer, we get 37.7, so our answer is 37.7 ft. Hope this helps
