A company plans to interview 23 recent graduates for possible employment. The company has four positions open. How many groups of four can the company select?

8855

Step-by-step explanation:

Data provided in the question:

Number of graduate candidates to be interviewed = 23

Number of positions open = 4

Now,

Number of  groups that company can select =

here,

n = total number of available choices = 23

r = number of individuals to be selected out of the given choices = 4

Thus,

Number of  groups that company can select = ²³C₄

=

=

= 8855

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
