Y = -2x + 4
The graph of the equation is the set of points that are solutions to the
equation.
The equation 2x + y = 4 is represented by the same graph.
For point (1, 2): 2 = -2(1) + 4 = -2 + 4 = 2.
Therefore, the point (1, 2) lies on the the graph of the equation.
For the
point (0, 2): 2 ≠ -2(0) + 4 = 0 + 4 = 4.
Therefore, the point (0, 2) DOES NOT lie on the graph of the equation.
Answer:
they climbed 3 miles
Step-by-step explanation:
Answer:
-71i + 12j +47k
Step-by-step explanation:
The notation of the distance moved
In x-direction = -71
Considering the left side as the positive y- direction;
In y-direction= 12
In z-direction = 47
Therefore, the vector notation is
Displacement r = -71i + 12j + 47k
The distance traveled by Raven in 1 hour at the given rate is 4.0 miles.
The given parameters:
- <em>Distance traveled by Raven = 2 2/5 miles</em>
- <em>Time of motion, t = 3/5 hour</em>
The speed of Raven motion is calculated as follows;
The distance traveled by Raven in 1 hour at the given rate is calculated as follows;

If two samples are selected from the same population, the two samples have exactly the same t statistics if the samples are same size and have the same variance and mean
The t-statistic is the ratio of the departure of the estimated value of a parameter from its hypothesized value to its standard error.
Variance is the expectation of the squared deviation of a random variable from its population mean or sample mean.
Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers
Hence, If two samples are selected from the same population, the two samples have exactly the same t statistics if the samples are same size and have the same variance and mean
