Abag contains four red marbles, two green ones, one lavender one, three yellows, and one orange marble. hint (see example 7.] how many sets of four marbles include none of the red ones?

The number of sets of four marbles include none of the red marbles= 840

Step-by-step explanation:

Given,

Total number of marble except red = 2+1+3+1

                                                           = 7

We have to calculate the number of sets of four marbles include none of the red marbles.

So,

The number of sets of four marbles include none of the red marbles can be given by,

    = 7 x 6 x 5 x 4

    = 840

So, the total number of required sets are 840.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
