The average can be calclculated as follows:
average = sum of number/number of numbers
average = (19+45) / 2 = 64/2 = 32
Part A
The graph is shown below as an attached image.
The diagram shows a straight line that goes through the two points (0,-3) and (1, -5)
I'm using GeoGebra to graph the line.
side note: (0, -3) is the y intercept which is where the graph crosses the y axis.
==================================================
Part B
Answer is choice 2
The graph can be written in the form y = mx+b, so it is linear
In this case, m = -2 is the slope and b = -3 is the y intercept
We can write the slope as m = -2 = -2/1. This tells us that we can move down 2 units and then over to the right 1 units to get from point to point. This process of "down 2, over to the right 1" happens when moving from point A to point B in the diagram below.
It is 32.0173263 because you add spaces to the decimal point and of course you don't put the zeros in
Answer:
80 degrees.
Step-by-step explanation:
The arc PS = 2 * the angles subtended by PS ( that is < PRS)
= 2 * 40 = 80 degrees.
Answer:
C) 3
Step-by-step explanation:
Plug in the values on c and d and solve
((3)^2 + (2)^2) - 2((3)^2 - (2)^2)
Solve inside the parenthesis first
(9+4) - 2(9-4) = (13) - 2(5)
Distribute the 2 and solve
13 - 10 = 3
