Sum of the interior angles of any triangle equal 180° .

Thus ;

[tex](x + 20) + 3x + 60 = 180[/tex]

[tex]4x + 80 = 180[/tex]

Subtract sides 80

[tex]4x + 80 - 80 = 180 - 80[/tex]

The student government at the local middle school surveyed students to help plan the end-of-year party. For the first sample, they surveyed every other person at sports practice after school. For the second sample, they surveyed every fifth person entering the cafeteria where all students eat. Which statement about the samples is true?

Answers

Answer:

Explained below.

Step-by-step explanation:

Convenience sampling is a kind of non-probability-sampling (i.e. all items doesn’t have an equivalent chance of being selected), which doesn’t comprises of random collection of items. Convenience sampling is where we take in items which are easy to reach.  This sort of sampling technique results in a biased sample.

Systematic sampling is a kind of probability sampling method in which individuals from a larger population are nominated according to a random initial point and a static, periodic interval. If the individual k is selected as the first sample then the sample space consists of every kth individual.

In this case the first sample is an example of convenience sample and the second is a systematic sample.

Answer: A

Sample 1 is biased.

Answers

Answer:

f(5.5) = 360

Step-by-step explanation:

function; f(x)=60x+30

where x = 5.5 as a number of hours the repairs take.

find f(5.5)

plugin value of x=5.5 back into the equation:

f(x) = 60x + 30

f(5.5) = 60(5.5) + 30

f(5.5) = 330 + 30

f(5.5) = 360

A line with a slope of 1 passes through the point (18, 15). What is its equation in slope-intercept form? Write your answer using integers, proper fractions, and improper fractions in simplest form.​

Answers

Answer:

y = x - 13

Step-by-step explanation:

Given parameters:

  Slope of the line  =  1

  Coordinate = (18, 15)

Unknown:

Equation of the line in slope-intercept format = ?

Solution:

The equation of a line is expressed as;

         y  =  mx + c

where y and x are the coordinates

          m is the slope

          c is the y-intercept

Now, sine x = 18 and y = 5, let us find c;

        5 = 1(18) + c

      5 = 18 + c

       c = -13;

 The equation of the line is;

       y  = 1(x) + (-13)

       y = x - 13

A number line is drawn left to right with integers spaced 1 centimeter apart. An ant crawls onto the number line at +2. It then crawls 3.5 centimeters left, 4.8 centimeters right, and 7.9 centimeters left.

Question 1
Part A

Where is the ant on the number line now?

Enter the correct answer in the box.

Answers

Answer:

Position = -5

Step-by-step explanation:

The number line is not shown, however the question can still be answered.

Given

Start Point: +2

Left Movement: 3.5cm and 7.9cm

Right Movement: 4.8cm

Required

Determine the Ant's position

To do this, we treat all left movements as negative and all right movements as positive.

So, we have:

Position = 2 - 3.5 - 7.9 + 4.8

Position = -4.6

Since the number line is spaced by 1cm, we have to approximate to the nearest integer.

Position = -5

Step-by-step explanation:

Since the graph is only moved you don't have to worry about the slope.

to move the graph up you add to the whole function and in this case, it only moved up 1.

What is the equation of a line that is parallel to the line y = 2x + 7 and passes through the point (–2, 4)? A. y = −12x + 3 B. y = 2x + 4 C. y = −12x − 2 D. y = 2x + 8

Answers

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept)

y = 2x + 7 ← is in slope- intercept form

with slope m = 2

Parallel lines have equal slopes, thus

y = 2x + c ← is the partial equation

To find c substitute (- 2, 4) into the partial equation

4 = - 4 + c ⇒ c = 4 + 4 = 8

y = 2x + 8 → D
