<h2>angle in triangle</h2>

because the triangle above is an isosceles triangle, then both angles are of the same value.

and one thing you should know, the angle above shows the straight angle.

<em>so the sum of all angles is 180</em><em>°</em>

<u>can be written like </u><u>this</u><u> </u><u>:</u>

(5x+13)°+(3x+7)°=180°

5x + 13 + 3x + 7 = 180

8x + 20 = 180

8x = 180 - 20

8x = 160

x = 20

<em>(*the third choice is correct)</em>

Answer= 20

The line is equal to 180 degrees (1/2 of 360 degrees) so you combine 5x+13 and 3x+7 and set it equal to 180 in order to find X which ends up being 20.

Answer: The Answer is D.

Step-by-step explanation: IT is D because a FUNCTION DOES NOT suppose to hit more than 1 point. You can also use the vertical line test meaning take a pencil or pen hold it up and down and drag it across you screen or paper, and if it hits more than 1 point it is NOT a FUNCTION.

Write an equation for the line of fit for this data in the form y=mx+b where x is latitude and y is temperature.

notka56 [123]

Answer:

$y = -x + 115$

Step-by-step explanation:

Given

See attachment for graph

Required

The equation of best fit

First, we pick two corresponding points on the graph,

We have:

$(x_1,y_1) =(55,60)$

$(x_2,y_2) =(45,70)$

Calculate slope (m)

$m = \frac{y_2 -y_1}{x_2 - x_1}$

This gives:

$m = \frac{70 - 60}{45 - 55}$

$m = \frac{10}{-10}$

$m = -1$

The equation is the calculated using:

$y = m(x - x_1) + y_1$

This gives

$y = -1(x - 55) + 60$

Open bracket

$y = -x + 55 + 60$

$y = -x + 115$

Ms. Rivera created two dot plots to compare the results of her recent science quiz for 1st period students compared to 7th perio

Lorico [155]

The dot plots is an illustration of charts and graphs

The average score of period 7 is greater than the average score of period 1

<h3>How to determine the period with the higher average?</h3>

From the dot plots in the complete question, we have the following frequency tables

<u>Period 1</u> <u>Period 7</u>

Score Students Score Students

55 1 65 1

70 1 75 3

75 6 80 5

80 6 85 6

85 2 90 3

90 3 95 2

95 1

The average is calculated using:

$\bar x = \frac{\sum fx}{\sum f}$

For period 1, we have:

$\bar x_1 = \frac{55 * 1 + 70 * 1 + 75 * 6 + 80 * 6 + 85 * 2 + 90 * 3 + 95 * 1}{1 + 1 + 6 + 6 + 2 + 3 + 1}$

Evaluate the sum

$\bar x_1 = \frac{1590}{20}$

Evaluate the quotient

$\bar x_1 = 79.5$

For period 7, we have:

$\bar x_7 = \frac{65 * 1 + 75 * 3 + 80 * 5 + 85 * 6 + 90 * 3 + 95 * 2}{1 + 3 + 5 + 6 + 3 + 2}$

Evaluate the sum

$\bar x_7 = \frac{1660}{20}$

Evaluate the quotient

$\bar x_7 = 83$

By comparison, 83 is greater than 79.5

Hence, the average score of period 7 is greater than the average score of period 1
