Paraphin [41]

Answer:

If you want to use the Rational Zeros Theorem, as instructed, you need to use synthetic division to find zeros until you get a quadratic remainder.

P: ±1, ±2, ±3, ±6  (all prime factors of constant term)

Q: ±1, ±7              (all prime factors of the leading coefficient)

P/Q: ±1, ±2, ±3, ±6, ±1/7, ±2/7, ±3/7, ±6/7  (all possible values of P/Q)

Now, start testing your values of P/Q in your polynomial:

f(x)=7x4-9x3-41x2+13x+6

You can tell f(1) and f(-1) are not zeros since they're not = 0Now try f(2) and f(-2):

f(2)=7(16)-9(8)-41(4)+13(2)+6

       112-72-164+26+6 ≠ 0

f(-2)=7(16)-9(-8)-41(4)+13(-2)+6

       112+72-164-26+6 = 0  OK!! There is a zero at x=-2

This means (x+2) is a factor of the polynomial.

Now, do synthetic division to find the polynomial that results from

(7x4-9x3-41x2+13x+6)÷(x+2):

-2⊥ 7   -9   -41    13     6

         -14   46   -10    -6          

      7  -23   5       3     0     The remainder is 0, as expected

The quotient is a polynomial of degree 3:

7x3-23x2+5x+3

Now, continue testing the P/Q values with this new polynomial.  Try f(3):

f(3)=7(27)-23(9)+5(3)+3

      189-207+15+3 = 0  OK!!  we found another zero at x=3

Now, another synthetic division:

3⊥ 7   -23    5     3

          21   -6   -3_

    7    -2    -1    0  

The quotient is a quadratic polynomial:

7x2-2x-1  This is not factorable, you need to apply the quadratic formula to find the 3rd and 4th zeros:

x= (1±2√2)÷7

The polynomial has 4 zeros at x=-2, 3, (1±2√2)÷7

A students' choir contains 25 children and only 5 of them play the piano. If a child is selected at random, what is the probabil
solniwko [45]

Answer:

probability that the child DOES NOT play the piano

P(E^{-})  =\frac{4}{5}

Step-by-step explanation:

A students' choir contains 25 children

n(S) =25

The number of students play the piano =5

Let 'E' be the event of the child play the piano so n(E) =5

The probability of that the child play the piano

 P(E) = \frac{n(E)}{n(S)}

 P(E) = \frac{5}{25}= \frac{1}{5}

Let 'E⁻ be the event of the child play does not play the piano

P(E^{-}) = 1- P(E)

P(E^{-}) = 1- \frac{1}{5} =\frac{4}{5}

<u>Conclusion</u>:-

probability that the child DOES NOT play the piano

P(E^{-})  =\frac{4}{5}

Answer:

12 inches

Step-by-step explanation:

180 divided by 3 = 6

Cassidy's goal is to raise more than $75 for charity. She has already raised $6. Now she is selling cupcakes for $3 each to reac
hodyreva [135]
$75= Cassidy's goal
c= number of cupcakes
a= $6 already raised

EQUATION:
75<$3c + a
substitute $6 in for a

75< $3c + 6
subtract 6 from both sides

69<3c
divide both sides by 3

23<c

Cassidy needs to sell at least 23 cupcakes to reach her goal of $75.


Answer:

FALSE: Cassidy will need to sell any number of cupcakes greater than 12 to reach her goal.

TRUE: Cassidy will need to sell any number of cupcakes greater than 23 to reach her goal.


Hope this helps!  :)
