The perimeter is all sides length added together. You can make an equation:5+5+x+x where x is the length.
5+5=10    18-10=8     There is two sides so you do eight divided by two

A college basketball coach has 12 players on his team. eight players are receiving scholarships, and four are not. the coach dec
EleoNora [17]

Solution: The given problem is a binomial distribution.

The probability that a team member receives a scholarship is \frac{8}{12} = 0.67

Therefore, the given problem follows binomial with n = 5 and p = 0.6667

Now the probability that 4 of 5 players selected are on scholarship is:

P(x=4) = \binom{5}{4} \times 0.6667^{4} (1-0.6667)^{5-4}

                  =5 \times 0.1976 \times 0.3333

                  =0.329

Therefore, the probability that 4 of 5 players selected are on scholarship is 0.329

aleksley [76]

Answer:

Answer is explained in the attached document

Step-by-step explanation:

Hessenberg matrix- it a special type of square matrix,there there are two subtypes of hessenberg matrix that is upper Hessenberg matrix and lower Hessenberg matrix.

upper Hessenberg matrix:- in this type of matrix  zero entries below the first subdiagonal or in another words square matrix of n\times n is said to be in upper Hessenberg form  if ai,j=0

for all i,j with i>j+1.and upper Hessenberg matrix is called unreduced if all subdiagonal entries are nonzero

lower Hessenberg matrix:-  in this type of matrix  zero entries upper the first subdiagonal,square matrix of n\times n is said to be in lower Hessenberg form  if ai,j=0  for all i,j with j>i+1.and lower Hessenberg matrix is called unreduced if all subdiagonal entries are nonzero.
