Answer:
The initial value of the linear relationship is
Step-by-step explanation:
we know that
The y-intercept is the value of y when the value of x is equal to zero
The initial value is the value of the linear function when the value of x is equal to zero
therefore
The initial value is the y-coordinate of the y-intercept of the linear function
Observing the graph
The y-intercept is the point
so
For
The value of y is equal to
<h2>The city's PR manager was wrong because the mean score of all ninth graders in the city is 83.</h2>
Step-by-step explanation:
The given observations are:
81, 96 and 72
The total number of observations = 3
We know that,
Mean =
= 83
∴ The mean score of all ninth graders in the city = 83
The city's PR manager was wrong because the mean score of all ninth graders in the city is 83.
First, you plot the coordinates to visualize the problem clearly. As you can see in the picture, the longest sides could either be one of those marked in red. This could be initially determined when you use visual estimation. We measure this using the distance formula: d = √[(x2-x1)^2 + (y2-y1)^2)]
Between coordinates (0,3) and (3,6)
d = √[(3-0)^2 + (6-3)^2)]
d= 4.24 units
Between coordinates (2,1) and (5,4)
d = √[(5-2)^2 + (4-1)^2)]
d= 4.24 units
They are of equal length. Both are the longest sides which measures 4.24 units.
