Here
Total students=30
Total donation =$500
Then
Remainder dollers=500-270
=230
Again
230/30
7.66
Hence $7.66 should collected by each students

11) Which of the following is zero of the polynomial x^3+x^2+x+1

Mrac [35]

Answer:

<em>Answer: -1</em>

Step-by-step explanation:

<u>The Polynomial Remainder Theorem</u>

It states that the remainder of the division of a polynomial f(x) by (x-r) is equal to f(r).

We have the polynomial:

$f(x)=x^3+x^2+x+1$

And we need to determine if x=1 and/or x=-1 are zeros of the polynomial.

Considering the polynomial remainder theorem, if we try any value for x, and the remainder is zero, then that value of x is a root or zero of the polynomial.

Find:

$f(1)=1^3+1^2+1+1$

f(1)=4

Thus, x=1 is not a zero of f(x)

Now, find:

$f(-1)=(-1)^3+(-1)^2+(-1)+1$

$f(1)=-1+1-1+1=0$

Thus, x=-1 is a zero of f(x)

If a garden hose can fill up a 5 gallon

lord [1]

Answer:

9 minutes

Step-by-step explanation:

We can write a proportion to solve

5 gallons 15 gallons

-------------- = ---------------

3 minutes x minutes

Using cross products

5x = 3*15

5x = 45

Divide by 5

5x/5 = 45/5

x = 9

How to find a least common demoniator

katrin [286]

To find the LCD first convert all integers and mixed numbers (mixed fractions) into fractions. Then find the least common multiple ( LCM ) of the denominators which is equal to the least common denominator ( LCD ). You can then rewrite each term as an equivalent fraction with the LCD .

Pls answer! I don’t know math @ all

Lana71 [14]

The probability that the outcome is a sum that is a multiple of 6 or a sum that is a multiple of 4 is $\frac{5}{12}$ .

Solution:

Total number of outcomes N(S) = 36

Let A be the sum that is a multiple of 6 and

B be the sum that is a multiple of 4.

Sum that is a multiple of 6 = (1, 5), (2, 4), (3, 3), (4, 2), (5, 1), (6, 6)

N(A) = 6

Sum that is a multiple of 4 = (1, 3), (2, 2), (2, 6), (3, 1), (3, 5),

(4, 4), (5, 3), (6, 2), (6, 6)

N(B) = 9

$$P(A)=\frac{N(A)}{N(S)}$

$$P(A)=\frac{6}{36}=\frac{1}{6}$

$$P(B)=\frac{N(B)}{N(S)}$

$$P(B)=\frac{9}{36}=\frac{1}{4}$

Probability that the outcome is a sum that is a multiple of 6 or a sum that is a multiple of 4:

$P(A \cup B)=P(A)+P(B)$

$$P(A \cup B)=\frac{1}{6} +\frac{1}{4}$

$$=\frac{2+3}{12}$ (Make the denominator same)

$$=\frac{5}{12}$

Hence the probability that the outcome is a sum that is a multiple of 6 or a sum that is a multiple of 4 is $\frac{5}{12}$ .

[18 POINTS] FIND 3 ORDERED PAIR THAT SOLVE THE EQUATION: 5x-3y= -7

NikAS [45]

If x=0 then we have -3y=-7
y=7/3 (0, 7/3) is your first pair
if y=0 then we have 5x=-7
x=-7/5 (-7/5, 0) second pair
now create a graph with these 2 points and any point in the line can be your 3rd pair.
