Use the pythagoras theorem:-
diagonal = sqrt(2^2 + 4^2) = sqrt 20 = 4.47 feet to nearest hundredth.
Answer:
Y are you making us do the test question you should have been payin attention in class
Step-by-step explanation:
Using a Laplace expansion along the first column, we have
The determinant of a 2x2 matrix is trivial,
So we have
Answer: ( 8.11 , 9.69)
the 95% confidence interval of the true mean weight
= ( 8.11 , 9.69)
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 = 8.9
Standard deviation r = 0.9
Number of samples n = 5
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
8.9+/-1.96(0.9/√5)
8.9+/-1.96(0.4025)
8.9+/- 0.79
= ( 8.11 , 9.69)
Therefore at 95% confidence interval (a,b) = ( 8.11 , 9.69)
Answer:Line E
Step-by-step explanation:
The equation is in the form of y=mx+b. M stands for slope and b is y-intercept. The y intercept is 4 and the only one with a positive y intercept is Line E. To check our answer we can see that the slope is positive which means the line is ascending(eliminating line t) and is greater than 1 which means that it is steeper than the line y=x(eliminating line p)
