Using the line of random numbers to run one simulation,
what proportion of students tried out for a sport?
O 0.40
A study reported that about 40% of high school students
have tried out for a sport at their school. To find out if this
applies to Jessica's school, she surveyed an SRS of 20
students. Nine of them said that they had tried out for a
sport. To see if this result is surprising, a simulation is to
be conducted to estimate the probability of obtaining a
sample result as high as this one.
Let 0-3 represent students who tried out for a sport and
4-9 represent students who did not try out for a sport.

8/total #of people (20) =.4

Answer 2

Using the line of random numbers to run one simulation, the proportion of students that tried out for a sport is .4

Calculation and Parameters:

Given that 40% of students tried out for a sport in a school

The survey is an SRS of 20 students.

Hence, to find the proportion of students that tried out for a sport with the use of a line of random numbers would be:

52644523488246266233

Where # is the number of people trying out is 8

2 2 3 2 2 2 3 3

Therefore,

8/total #of people (20)

=.4

If m∠10 = 70, then find the m∠14 and state the angle relationship.

Answers

The measure of m∠14 is 110 degrees and the angle relationship is a supplementary angles

Let us assume that angle m∠10 and m∠14 are supplementary, this means that the sum of both angles will be 180 degrees.

Since the angles are supplementary, hence the required expression will be:

m∠10 + m∠14 = 180

Given that m∠10 = 70 degrees

70 + m∠14 = 180

m∠14 = 180 - 70

m∠14 = 110 degrees

Hence the measure of m∠14 is 110 degrees and the angle relationship is a supplementary angle.

- 67 minus what gives me 0

Answers

Answer:

-67

Step-by-step explanation:

-67 minus -67 = -67+67 (since two negatives make a positive) =0

Answer:

Step-by-step explanation:

For the math problem, "67 minus what equals 0?", we can make it into an algebra equation as follows:

67 - X = 0

Then, we solve for X. To solve for X, we first subtract 67 from both sides:

67 - 67 - X = 0 - 67

-X = -67

Next, you multiply each side by -1 to remove the minus from the X:

-X(-1) = -67(-1)

X = 67

Therefore, the answer to "67 minus what equals 0?" is 67 as illustrated below:

67 - 67 = 0

The 2nd option does not represent a function.

A function is a relation in which no two ordered pairs have the same first component and different second components.

We need to ask ourselves, does every first element (or input) correspond with EXACTLY ONE second element (or output)? 

In this case, the answer is no.  The input value of 1 goes with two output values, -1 and -5.   The same goes with the input value of 2, which also goes with two output values: -2 and -4.

It only takes one input value to associate with more than one output value to be invalid as a function.

I also did the Vertical Line Test to show why Option 2 is not a function. The Vertical Line Test allows us to know whether or not a graph is actually a function. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.

However, the graph shows that the two vertical lines crossed the graphed twice (there are 2 points in each line). The graphed points failed the vertical line test. Therefore, Option 2 is NOT a function.

  y = -3/4(x -2)

Step-by-step explanation:

You are given point (2, 0) on the new pipeline. To find the equation of it, you need to know the slope of the line on the graph. A careful look at the graph shows you the line goes through grid points that are separated by 4 units horizontally, and 3 units vertically. For a positive horizontal change, the vertical change is negative, so the slope is ...

  m = rise/run = -3/4

The point-slope form of the equation for a line is ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

For m = -3/4 and (h, k) = (2, 0), the equation is ...

  y = -3/4(x -2)

_____

Additional comments

If you use the distributive property to eliminate parentheses, the equation becomes ...

  y = -3/4x +3/2

The slope of the red pipeline can also be determined by considering the slope of the blue pipeline. The two marked points on that line have a horizontal separation of 3 and a vertical separation of 4. Its slope is ...

  m = rise/run = 4/3

The slope of the perpendicular (red) line is the opposite reciprocal of this:

  -1/m = -1/(4/3) = -3/4 . . . . as we determined from the red line's graph

11. Liza earned some money delivering newspaper .She bought a
battery for $1.95, and gave her mother $30. She bought a ring
for $7.20, and then spent half of the remaining money on a radio.
If Liza has $38.50 left, how much money did she earn delivering
newspapers?
anonh the solution set.

Answers

Answer: $116.15

Step-by-step explanation:

We first would start with the last  thing, the $38.50 Lisa has left! From reading the word problem, we can tell that she had another $38.50 she spent on a radio.She spends $7.20 (ring) + $1.95 (battery) before this and gives her mom $30.

All of these are subtractions from the initial amount:

x - 1.95 - 30.00 - 7.20 - 38.50 = 38.50

x - 77.65 = 38.50

x = $116.15

what is the multiplicative inverse of -3 1/2
A) 7/2
B) -2/7
C) 9​

Answers

Answer:

B or -2/7 should be correct

Step-by-step explanation:

First, I would find out the improper fraction of -3 1/2

The improper fraction of -3 1/2 is -7/2

To find the multiplicative inverse, we will flip the numerator and the denominator.

Multiplicative inverse of -7/2 = 2/-7

2/-7 is a weird way to write a fraction, so to convert into a reasonable fraction, we will multiply both the numerator and denominator by -1.

2/-7 x -1/-1 = -2/7

Therefore, B should be your answer

Kind requests:

Please give me brainliest :)

Answer:
B) -2/7

Explanation:
this is because, you start out by simplifying -3 1/2 to get -7/2 next you find the multiplicative inverse of which is -2/7

In 2010, the population of a city was 168,000. From 2010 to 2015, the population grew by 7%. From 2015 to 2020, it fell by 6%. How much did the population decrease from 2015 to 2020, to the nearest 100 people?

Answers

Answer:

169,000 people

Step-by-step explanation:

increase from 2010-2015:

168000/100 = 1680 = 1%

1680 x 7 = 11,760 people

population at 2015 = 168000+11760 = 179,760

decrease from 2015-2020:

179760/100 = 1797.6 = 1%

1797.6 x 6 = 10,785.6 people

population at 2020 = 179760-10787.6 = 168,974.4 people

rounded to the nearest 100 = 169,000 people
