10/15 idk if this is right for sure let me know
Answer: f) None of the above
= ( 5.283, 5.917)
Therefore at 90% confidence interval (a,b) = ( 5.283, 5.917)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 5.6ft
Standard deviation r = 1.0ft
Number of samples n = 27
Confidence interval = 90%
z(at 90% confidence) = 1.645
Substituting the values we have;
5.6+/-1.645(1.0/√27)
5.6+/-1.645(0.192)
5.6+/-0.317 ft
= ( 5.283, 5.917)
Therefore at 90% confidence interval (a,b) = ( 5.283, 5.917)
.76 cents per cup.
Their are 16 cups in a gallon.
2 gallons would be 32cups.
Divide 24.32 by 32.
0.76 is your answer
Answer:
v =7/75
Step-by-step explanation:
5/3v = 125/7
cross multiply
5*7 = 125 *3v
35 = 375v divide by 375
v = 35/375
v =7/75
Answer:
4.5m/s^2
Step-by-step explanation:
Given data
Mass= 200kg
Force= 895N
Required
the acceleration a
We know that
F=ma
a= F/m
substitute
a= 895/200
a= 4.5 m/s^2
Hence the accelaration is 4.5m/s^2
