Answer:

Option C is correct, The scatter plot shows a positive association because y increases as x increases.

Step-by-step explanation:

We are given a graph of scatter plot of points. We need to choose correct option using graph.

Option A: The point (18,2) is an outlier. This point is not shown on graph.

False.

Option B: The scatter plot show linear association. This is not linear association because points are not col-linear.

False

Option C: The scatter plot shows a positive association. This is positive association because y increases as x increases.

True

Option D: The scatter plot shows no association. This is false because it shows positive association.

False

1. A polynomial means it has more than one term.
a. has 4 terms
b. has 1 term (not a POLYnomial)
c. has 3 terms
d. has 2 terms
2. The first word in a polynomial description tells the degree (max amount of exponents) of the expression, and the second word tells how many terms it has.
a. This answer means it's maxed exponent is to the fourth power, which it's not. (WRONG)
b. This answer means that it has a max exponent to the third power, which is true, and it also says it has three terms, which is also true. (CORRECT)
3. You must combine like terms in this polynomial.
=> 14x^2 - 6x^2 =8x^2
=> 5x + 2x = 7x
=> -8
d. This answer combines all the terms correctly.
4. To simplify this equation, you must first distribute the negative to all of the second equation.
(4x^2 -3x+2) + (-2x^2-5x+7)
Now, combine like terms.
=>4x^2 - 2x^2 = 2x^2
=>-3x - 5x = -8x
=>2 + 7 = 9
d. This answer simplifies it correctly

16x − 7 ≤ − 71<br><br> Find the solution set of the inequality

natka813 [3]

Answer:

x $\leq -4\\$

Step-by-step explanation:

Add 7 to other side making equation 16x $\leq$ -71+7

16x $\leq$ -64

16 goes into -64 -4 times.

Answer would give you x $\leq$ -4

To check, you could substitute -4 into the inequality

16(-4)-7 $\leq$ -71

-71 $\leq$ -71 check

16(-10)-7 $\leq$ -71

-167 $\leq$ -71 check

The distance versus time plot for a particular object shows a quadratic relationship. Which column of distance data is possible

Viktor [21]

Answer:

(A) column A

Step-by-step explanation:

The distance values in column A are:

0, 1, 4, 9, 16, 25 and 36

If you just look at these values, these are the squares of 0, 1, 2, 3, 4, 5 and 6 which shows that distance in column A versus time would show a quadratic plot.

For the values showing a quadratic relationship, the second differences in the values are constant. This means, if we find the differences of two consecutive terms for all the terms and then find the difference of the answers resulted in previous step, these should be a constant for the quadratic function.

Differences in the values of Columns A are:

1, 3, 5, 7, 9, 11

The difference in these differences are:

2, 2, 2, 2, 2

which is a constant. Since, the difference is being calculated two times, it is known as second difference. The second difference must be constant for a quadratic relationship. For the other columns, the second differences are not constant.

Therefore, the correct answer is option A.

Simplify and expand (1/3)to 2nd power × 18 + (1/2)to 2nd power × 4

Pepsi [2]

Step 1. Use Division Distributive Property $( \frac{x}{y} ) ^{a} = \frac{ x^{a} }{ y^{a} }$

Step 2. Simplify $3^{2}$ to $9$

$\frac{1}{9} *18+( \frac{1}{2} ) ^{2}*4 
$

Step 3. Use Division Distributive Property $( \frac{x}{y} ) ^{a} = \frac{ x^{a} }{ y^{a} }$

$\frac{1}{9} *18+ \frac{1}{ 2^{2} } *4$

Step 4. Simplify $2^{2}$ to $4$

$\frac{1}{9} *18+ \frac{1}{4} *4$

Step 5. Simplify $\frac{1}{9} *18$ to $\frac{18}{9}$

$\frac{18}{9} + \frac{1}{4} *4$

Step 6. Simplify $\frac{18}{9}$ to $2$

$2+ \frac{1}{4} *4$

Step 7. Simplify $\frac{1}{4} *4$ to $1$

$2+1$

Step 8. Simplify

$3$

Done! Your answer is 3
