The table shows information about some cds.
type rock pop jazz
number of cds 2 x 2x + 5
a cd is chosen at random.
the probability it is rock is
20
1
work out the probability it is jazz.

27 over 40

Step-by-step explanation:

2( 11+5) over 40 = 27 over 40

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

your answer would be 12
