). a competitive cheer team allows only the top 4% of athletes who try out to be part of the team. if the team tryout scorecard has a mean of 200 and a standard deviation of 10, which of the following can be used as a minimum qualifying score to join the cheer team?

a.) 8
b.) 192
c.) 217
d.) 202

The minimum qualifying score to join the cheer team is 202.

Step-by-step explanation:

the competitive team allows only top 4% of athletes

if team tryout to score a mean of 200 and a standard deviation of 10 then

our quadratic equation is given as  

in order to find that do we have the real roots of a quadratic equation , the discriminant must be greater or equal to 0. the discriminant is denoted by d and given by the formula

where b is the coefficient of the middle term containing x, a is the coefficient of the term containing and the c is the constant term.

hence we have

a = 1 , b = 5 and c = 7

to calculate d

Hence we see that the discriminant.

d

step-by-step explanation:

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
