Answer:
-1/4
Step-by-step explanation:
The slope is found by
m = (y2-y1)/(x2-x1)
= (-1-2)/(7- -5)
= (-1-2)/(7+5)
= -3/12
= -1/4
Answer:
Hence the critical value for the right-tailed test is . Since the test value is greater than the critical value so we reject the null hypothesis.
Step-by-step explanation:
Hypotheses are:
Here we have s_{1}=6800 and s_{2}=3900. Here we will use F -test. The Value of test statistics is
Here the degree of freedom of the numerator is and The degree of the denominator is
The critical value for the right-tailed test is . Since the test value is greater than the critical value so we reject the null hypothesis.
There is no chance that the cube will roll a 7
Answer:
CD = 3.602019190339
Step-by-step explanation:
CD = DA - CA
DA = DB×Cos(29) = 18.7×cos(29) = 16.355388523507
BA = BA×cos(43) = 18.7×cos(43) = 13.676314220278
CA = BA÷tan(47) = 13.676314220278÷tan(47) = 12.753369333168
Then
CD = 16.355388523507 - 12.753369333168 = 3.602019190339
Answer:
Option C.
Step-by-step explanation:
Let and are two line.
If , then system of equations have infinite number of solutions.
If , then system of equations have no solution.
If , then system of equations have unique solution.
The given equations are
These equations can be rewritten as
Here, .
Since, , therefore, the system of equations have no solution.
Hence, option C is correct.
