Answer:

1.10

Step-by-step explanation:

Given the probability distribution :

x : ___ 0 ___ 1 ___ 2

p(x)__0.15 _0.60 __0.25

The expected value is obtained by:

Σ(X * p(x))

(0 * 0.15) + (1 * 0.60) + (2 * 0.25)

0 + 0.60 + 0.50

= 1.10

When testing for current in a cable with sixsix ​color-coded wires, the author used a meter to test threethree wires at a time.
Virty [35]

Answer:

20 tests

Step-by-step explanation:

There are six different wires, and for each test the author picks three, this means that each test is a combination of three out of six wires (₆C₃) . The number of total combinations possible is given by:

_6C_3=\frac{6!}{(6-3)!3!}\\_6C_3=\frac{6*5*4}{3*2*1}\\_6C_3=20

20 tests are required to verify every possible pairing of three wires.

What equation is represented by the graph below
mamaluj [8]

Answer:

y= -2/3x - 2

Step-by-step explanation:

So, the easiest thing to find first is your y-intercept, or the point in which the line crosses the y-axis. In this graph, the y intercept would be -2. Now, we can find the slope. One way to find the slope is to start at a point and count the numbers it rises and then the number it runs. Or, you can choose two points, like (0,-2) and (3,-4) and use the formula for slope, (y2-y1) / (x2-x1). Plug those numbers in and get (-4 minus -2)/ (3 minus 0), which would give you -2/3.
