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.
O 0.45

8/total #of people (20) =.4
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:
52644523488246266233Where # is the number of people trying out is 8
2 2 3 2 2 2 3 3
Therefore,

Seven less than twice a
number is negative five.
What is the number?
Answer:
n = 1
Step-by-step explanation:
Represent the number by n. Then "seven less than twice a number is -5 becomes 2n - 7 = -5
Next we must solve for n. Adding 7 to both sides yields 2n = 2, so that
n = 1

Please answer this fast. This was due October 6th and I need to get it done!!!!! The energy E of a moving object is called its
kinetic energy. It is calculated using the formula E = { mv2,
where m is the object's mass in kilograms and v is its
speed in meters per second. The units of kinetic energy are
kilograms - meters
abbreviated as kg • m²/s2.
seconda
a. Solve the given formula for m.
b. What is the mass of an object moving at 10 m/s with a kinetic
energy of 2500 kg · mº/s2?
. n
Answer:
Question a:
[tex]{ \rm{kinetic \: energy = \frac{1}{2} m {v}^{2} }} \\ [/tex]
• then let's make m the subject:
[tex]{ \rm{E = \frac{1}{2}m {v}^{2} }} \\ \\ { \rm{m {v}^{2} = 2E }} \\ \\ { { \green{ \boxed{ \boxed{ \bf{m = \frac{2E}{ {v}^{2} } }}}}}} \\ [/tex]
Answer: m = 2E/v²
Question b:
[tex]{ \rm{m = \frac{2E}{ {v}^{2} } }} \\ \\ { \rm{m = \frac{(2 \times 2500)}{ {10}^{2} } }} \\ \\ { \rm{m = \frac{5000}{100} }} \\ \\ { \boxed{ \boxed{ \rm{ \: m = 50 \: kg \: }}}}[/tex]

How can I find 75% of any number?
Answer:
75% can be converted into a decimal, any percentage can.
Once converted, 75% is actually .75
At this point you can move the decimal place two place up, and put it over 100, in a fractal form
75/100
You can then simplify this to
3/4
You can then use this fraction as a conversion factor with any number, for example if we took the number 8
8∗3/4
2∗3/1=6

Find the slope of each line.
1)
2)
у
To find the slope of a line, remember:
[tex]slope=\frac{rise}{run}[/tex].
Also, the points that you choose to use to calculate your rise and your run must meet at an exact point, not in the middle of a block. In your graphs the points are the little blue dots, so that's already been done for you and that's what we'll use to calculate the slope!
Also, recall that the rise is how many blocks the line has changed vertically (so is one point lower/higher than another point)
The run is how many blocks the line has changed horizontally (so how many blocks over is the next point)
Therefore, for #1 we can see that the point on the right is over 3 blocks (run), and it goes down 1 block (rise).
So for #1, your answer is: [tex]slope=\frac{rise}{run}=\frac{-1}{3}[/tex] or [tex]-\frac{1}{3}[/tex]
For #2 we see that one point is higher by 3 blocks (rise) and it also goes over one block (run)
So, your answer to #2 is: [tex]slope=\frac{rise}{run}=\frac{3}{1}=3[/tex]

A student wrote a photography manual which she plans to sell online for $ 13 per copy. Her total expenses were $ 55. Write a linear equation to show the relationship between x , the number of manuals the student sells, and y , the profit the student earns.
Answer:
y = 13x - 55
Step-by-step explanation:
So this is what we know
Selling price = $13 per copy
Expenses = $55
The formula for profit in this case is:
Profit = total selling price - expenses
In which y is the profit
The total selling price is 13x. x here is for the number of manuals she sells
The expenses are $55.
This then becomes y =13x - 55

13
and passes through the point
(
15
,
−
31
)
?
y=-5x-44
Step-by-step explanation:
5x+y=13 passes through (15,31)
rearrange the equation to y=mx+c
5x+y=13
y=-5x+13
substitute the points (15,31)
y=5x+c
31=5(15)+c
31=75+c
-44=c
y=-5x-44
Can be written as 5x+y=-44

In Earth's southern hemisphere, the summer season is from December to March and winter is from June to September. The table shows the highest temperatures recorded at the South Pole for three different months.
Graph model:
South Pole Temperatures
Month Highest temperature (°F)
January 6
June –24
November –2
Each month's highest recorded temperature is plotted on the number line.
4. Which month had the coldest of the three temperatures? Explain.
#4
June is the most coldest.
How?
Mention the temperatures
January=+6°F
June=-24°F
November=-2°F
Lowest is the coldest .(June is the coldest month)
January = 6°F
June = -24°F
November = -2°F
By the above given observation we can say that June is the coldest as it has the lowest temperature in all.
