Answer:
B
Step-by-step explanation:
-3 squared is 9
9 -(-3) =12
Answer:
The value of test statistic is 1.338
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 16.000
Sample mean, 
= 16.218
Sample size, n = 22
Alpha, α = 0.05
Sample standard deviation, s = 0.764
First, we design the null and the alternate hypothesis
We use one-tailed t test to perform this hypothesis.
Formula:
Putting all the values, we have
Thus, the value of test statistic is 1.338
Answer:
x = 30
Step-by-step explanation:
The figure will be a parallelogram when adjacent angles are supplementary:
(3x)° + (x+60)° = 180°
4x +60 = 180
4x = 120
x = 30
The value x = 30 makes the figure a parallelogram.
_____
It also makes the figure a rectangle.
The answer is f= 2e+g / 3 I think
Answer:
x = 1 y= 3
Step-by-step explanation:
Multiply each equation by the value that makes the coefficients of y opposite.
Simplify.
Add the two equations together to eliminate y from the system.
Divide each term by 8 and simplify.
Substitute the value found for x into one of the original equations, then solve for y.
The result can be shown in multiple forms.
Point Form:
(1,3)
Equation Form:
x=1 ,y=3
