Answer:
x= -7
Step-by-step explanation:
Simplify both sides of the equation.
4(1−x)+2x=−3(x+1)
(4)(1)+(4)(−x)+2x=(−3)(x)+(−3)(1)(Distribute)
4+−4x+2x=−3x+−3
(−4x+2x)+(4)=−3x−3(Combine Like terms)
Add 3x to both sides.
−2x+4+3x=−3x−3+3x
x+4=−3
Subtract 4 from both sides.
x+4−4=−3−4
x=−7
Hope this explanation helps. :)
2.83 or 3 (rounded) because 34/12 is 2.83
Answer:
Reflection over the x-axis
Step-by-step explanation:
To get from Triangle A to Triangle B, Triangle A must be reflected over the x-axis. On Triangle A, the left-most point is at (1, -2). The corresponding point on Triangle B is at (1, 2). The rule for reflecting over the x-axis is (x, y) -> (x, -y). So, (1, -2) -> (1, 2).
I hope this helps :))
Answer:
The <em>p</em>-value of the test is 0.0512.
Step-by-step explanation:
The <em>p</em>-value of a test is well-defined as per the probability, [under the null hypothesis (H₀)], of attaining a result equivalent to or more extreme than what was the truly observed value of the test statistic.
In this case the output of the t-test_ind method from scipy module is provided as follows:
Output = (-1.99, 0.0512)
The first value within the parentheses is the test statistic value.
So the test statistic value is, -1.99.
And the second value within the parentheses is the <em>p</em>-value of the test.
So the <em>p</em>-value of the test is 0.0512.
