Nikolay [14]

Answer:

Mr.Pratt can select three students to win these awards in 2,600 ways.

Step-by-step explanation:

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

{n\choose k}=\frac{n!}{k!(n-k)!}

Mr. Pratt has three prizes to give away.

The total number of students in his class is, <em>n</em> = 26.

He has <em>k</em> = 3 prizes, namely a pencil, an eraser, and a homework pass.

Compute the number of combinations of three students Mr. Pratt can select from 26 students to give away the prizes as follows:

{n\choose k}=\frac{n!}{k!(n-k)!}

     =\frac{26!}{3!(26-3)!}

     =\frac{26!}{3!\times 23!}

     =\frac{26\times25\times24\times23!}{3!\times23!}

     =2600

Thus, Mr.Pratt can select three students to win these awards in 2,600 ways.

Suppose Vicky deposits $19.00 into a savings account. The interest rate is 4% per year. Find the number of years it takes to ear
ollegr [7]

Answer:

Step-by-step explanation:

Simple Interest formula S.I = Principal * rate * time

S.I = P * r *t

In this case Simple interest ; S.I = $4.56

Principal; P = $19.00

rate; r = 4% or 0.04 as a decimal

t = total duration of investment in years.

Next, plug in the numbers in the S.I formula and solve for <em>t</em>

4.56 = 19 * 0.04 * t

4.56 = 0.76t

Divide both sides by 0.76;

4.56 / 0.76 = t

t = 6

Therefore, it will take 6 years to earn a simple interest of $4.56
