1.886 to the nearest hundredth would be 2.
we know that
If line b is perpendicular to line a, and line c is perpendicular to line a,
then
line b and line c are parallel
and two lines parallel have the same slope
so
<u>Find the slope of the line b</u>
Let
The formula to calculate the slope between two points is equal to
substitute
therefore
<u>the answer is</u>
<u>the slope of the line c is</u>
Answer:
D. The difference of the means is not significant because the re-randomizations show that it is within the range of what could happen by chance.
Step-by-step explanation:
The treatment group using System A reported a mean of 18.5 lost bags per day. The treatment group using System B reported a mean of 16.6 lost bags per day.
The best conclusion that can be made is - The difference of the means is not significant because the re-randomizations show that it is within the range of what could happen by chance.
As we know, in statistics, nothing happens by chance. So, this option is correct.
Answer:
The correct answer is YES, it is a solution of the system.
Step-by-step explanation:
The system of equations have equations 2x − 3y = −5 and 4x − 4y = −4.
We need to find whether of not (2,3) is a solution to the system of equation.
We multiply the equation 2x − 3y = −5 by 2 and subtract it with the other equation. This gives us,
⇒ 4x - 6y +10 -4x +4y -4 = 0
⇒ 2y = 6
⇒ y = 3.
⇒ x = 2.
Thus ( 2 , 3 ) is the solution.
Answer:
The co variance of the midterm and final exam scores is 58.76.
Step-by-step explanation:
The formula to compute the sample co variance is:
The values are computed in the table below.
Compute the co variance as follows:
Thus, the co variance of the midterm and final exam scores is 58.76.
