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

Determine whether the data distribution appears to be positively skewed, negatively skewed, or symmetric.

Licemer1 [7]

Answer:

Negatively skewed

Step-by-step explanation:

Arrange this data in ascending order:

46, 50, 57, 58, 59, 59, 65, 66, 77, 80

and draw the bar chart as shown in attached diagram.

The data distribution appears to be negatively skewed (or left skewed), because the scores fall toward the higher side of the scale and there are very few low scores. The mean is also to the left of the peak.

Granola bars cost 45 cents, gum cots 35 cents, and crackers cost 50 cents. Lauren buys two different items. She pays with a 1 do

dangina [55]

Answer:

A gum and a cracker

Step-by-step explanation:

She receive 3 of the same type of coin as change => the leftover change should be divisible by 3

If she buy a gum and a cracker, she would be leftover with 100 - (50+35) = 15 cents.

And that is divisible by 3, so we can conclude she bought a gum and a cracker.
