Students at Hampton Middle School sold T-shirts as a school fundraiser. Sylvie asked 12 random seventh-grade students how many T

EastWind [94]

Answer:

Answer is 4.1 shirts.

Step-by-step explanation:

The number of T-shirts sold by each students are :

3, 4, 8, 5, 2, 5, 0, 5, 3, 4, 3, 7

To find out mean of the data we apply formula of mean :

Sum of the values / total number of the value

Mean = (3+4+8+5+2+5+0+5+3+4+3+7) / 12

= 49 / 12 = 4.08

When rounded to the nearest tenth we get 4.1 shirts.

The mean of the data set rounded to the nearest tenth is 4.1 .

stock = {"banana": 6, "apple": 0, "orange": 32, "pear": 15}

for item in prices:

print item + ":"

print "price: " + str(prices[item])

print "stock: " + str(stock[item])

Step-by-step explanation:

prices = {"banana": 4, "apple": 2, "orange": 1.5, "pear": 3}

stock = {"banana": 6, "apple": 0, "orange": 32, "pear": 15}

for item in prices:

If polynomial p(x) is divided by x + 4, the quotient is x^2-7x+34-144/x+4. Which of the following must be true?

Ber [7]

Answer:

B. P(-4)=-144

Step-by-step explanation:

From the question, we have that:

$\frac{p(x)}{x + 4} = {x}^{2} - 7x + 34 - \frac{144}{x + 4}$

This implies that:

$p(x)=(x + 4)( {x}^{2} - 7x + 34) - 144$

To find p(-4), we put x=-4

$p( - 4)=( - 4+ 4)( {( - 4)}^{2} - 7 \times - 4 + 34) - 144$

$p( - 4)=( 0)( {( - 4)}^{2} - 7 \times - 4 + 34) - 144 = - 144$

To find p(0), we put x=0 to get:

$p( 0)=( 0+ 4)( {( 0)}^{2} - 7 \times 0+ 34) - 144$

$p( 0)=(4)( 34) - 144 = - 8$

The correct answer is B

ms. wilson draws a model of the factorization of a polynomial with integer factors. her model is partially complete. which equat

Oliga [24]

I'll just factor the above equation.

x² + 18x + 80

x² ⇒ x * x
80
can be:
1 x 80
2 x 40
4 x 20
5 x 16
8 x 10 Correct pair

(x+8)(x+10)
x(x+10) +8(x+10) ⇒ x² + 10x + 8x + 80 = x² + 18x + 80

x+8 = 0
x = -8

x+10 = 0
x = -10

x = -8

(-8)² + 18(-8) + 80 = 0
64 - 144 + 80 = 0
144 - 144 = 0
0 = 0

(-10)² + 18(-10) + 80 = 0
100 - 180 + 80 = 0
180 - 180 = 0
0 = 0

I think the algebra tiles will not be a good tool to use to factor the quadratic equation because the equation is not a perfect square quadratic equation.
