Answer:
6
Step-by-step explanation:
Given that the coordinate plane, three of the vertices of the rectangle are located at (-1.25, -0.25),
(-1.25, 0.25), and (1.25, 0.25)
The length L of the shape will be:
L = 0.25 - ( - 0.25 )
L = 0.25 + 0.25
L = 0.5
The width of the shape will be:
W = 1.25 - ( - 1.25)
W = 1.25 + 1.25
W = 2.5
Perimeter P = 2L + 2W
Substitute the Length and the width into the formula
P = 2(0.5) + 2(2.5)
P = 1 + 5
P = 6 metres
Therefore, the perimeter of the shape is 6 metres
Answer
7.53
1,227 then divide that by 163 so
1,227÷163= 7.53 so then you would go
163 and multiply 7.53 and you would get 1,227
Answer:
B. Hannah is likely to be incorrect because 9 is not contained in the interval.
Step-by-step explanation:
She construct a 99% confidence interval for the difference between means and gets the interval (0.4, 8.0).
This means that there is 99% confidence that the true difference between means is within this interval.
The left 1% corresponds to the tails of the distribution: there is 0.5% probability that the difference between means is below 0.4 and 0.5% probability that the difference between means is above 8.0.
As she claims that 9 hours is the true difference, we can say that there is less than 0.5% that she is correct. In others words, is likely to be incorrect.
