Answer:

1. Figure C has reflection symmetry.

2. A and D have reflection symmetry.

Step-by-step explanation:

1. When you cut the arrow horizontally, you get the same shape on each side.

2. When you divide them, you should have symmetry, meaning they are the same when divided/cut.

Answer:

1. Option C

2. Option A and Option D.

Step-by-step explanation:

Reflective symmetry:

If a figure is reflected across a line such that the reflected figure is exactly the same as the original and the same distance from the line, then the line is called axis of symmetry.

If a figure has at least one line of symmetry, then the figure has Reflective symmetry.

In part 1, only figure C has horizontal axis of symmetry. Therefore the correct option is C.

In part 2, figure A and D have vertical axis of symmetry. Therefore the correct options are AD.

FrozenT [24]

Answer:

The answer is B: (1,2)

Step-by-step explanation:

(solved using elimination method)

-2x+y=0

y=x+1

-x+y=1

-2x+y=0

x+y=-1

-x=-1

x=1

-1+y=1

y=2

Natalie’s income statement for the month of October is shown. Natalie monthly income statement for October. Total wages are 3,00
rusak2 [61]

Natalie’s net income for the month of October is $1,930.

<h2>Net Income </h2>

The net income of a person is the income of the person that is left with him after deducting all of his\her expenses and deductions.

\rm Net\ Income = Total\ salary - Total\ expenses - Deductions

<h2 /><h2>Given to us</h2>
  • Natalie's monthly income statement for October. Total wages are 3,000 dollars.
  • Total expenses are 1,070 dollars.

<h3 /><h3>Natalie’s net income</h3>

the total wage Natalie is already given is $3,000, and her expenses as $1,070, while there are no deductions from his salary. therefore,

\rm Natalie 's\ Net\ Income= Total\ salary - Total\ expenses - Deductions

                                 =\$3,000 - \$1,070 -\$0\\= \$1930

Hence, Natalie’s net income for the month of October is $1,930.

Use a graphing calculator to find the value of the correlation coefficient r and determine if there is a strong correlation amon
Natali [406]

The value of the correlation is -0.0721 and it is a weak negative correlation

<h3>How to determine the correlation coefficient?</h3>

The points are given as:

(12, 28), (15, 50), (18, 14), (21, 28), (24, 36)

Enter the above points in a graphing calculator.

From the graphing calculator, we have the following summary:

<u>X Values</u>

  • Sum X = 90
  • Mean = 18
  • ∑(X - Mx)^2 = SSx = 90

<u>Y Values</u>

  • Sum Y = 156
  • Mean = 31.2
  • ∑(Y - My)^2 = SSy = 692.8

<u>X and Y Combined</u>

  • N = 5
  • ∑(X - Mx)(Y - My) = -18

<u>R Calculation</u>

r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))

This gives

r = -18 / √((90)(692.8)) = -0.0721

So, the correlation coefficient is -0.0721

The above is a negative correlation because it is less than 0 and it is a weak correlation because it is closer to 0 than -1

Hence, the correlation is a weak negative correlation
