Teesha is in the french club. there are 31 students in the club. the french teacher will pick two students at random to guide visiting students from france. what is the probability that teesha will be picked as a guide? hint: teesha must be picked first or second.

You would put 2 over 31 to determine the probability. You would divide 31 by 2 and get 2/31 which doesn't reduce. If you divide 31 by 2 you get .064516129... When you round this, the probability of her being picked is 6%.

Our required probability that Teesha will be picked as a guide is given by .

Step-by-step explanation:

Since we have given that

Number of students in a club = 31

Number of students will be picked up at random to guide visiting students from France = 2

We need to find the "Probability that Teesha will be picked as a guide " i.e.

So, it will be

Hence, our required probability that Teesha will be picked as a guide is given by .

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
