Answer:
Sarah's reasoning sounds good to start. She rounded the available bags and their content, so the result, 4000 bracelets, should be really easy to reach.
The exact numbers are 214 bags * 22 bracelets / bag = 4708 bracelets; so as you see, Sarah took care of having room to loose some beads and yet the beads will be enough to make 4000 bracelets.
Of course, if you want to be sure, you should ask Sarah some questions. For example:
1) What proportion of beads are normally deffective?
2) What proportion of beads are normally lost when crafting?
So, if Sarah did not take into account those proportions she migth be overestimating the number of bracelets they can make.
Sarah's assumptions of having enough beads for at least 4000 bracelets is correct.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Sarah who has 214 bag of beads each bag has enough beads for 22 bracelets
According to Sarah, there are enough beads for at least 4000 bracelets.
Mathematically -
x[e] ≥ 4000
Actual number of beads she could make = 22 x 214 = 4708 = x[a]
Since, x[a] > x[e], we can say that Sarah's assumptions are correct.
Therefore, we can say that Sarah's assumptions are correct.

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.

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:

What’s the answer to this geometry problem?
Answer:
x = 3
Step-by-step explanation:
(13x - 2) and (12x + 1) are vertically opposite angles and are congruent , so
13x - 2 = 12x + 1 ( subtract 12x from both sides )
x - 2 = 1 ( add 2 to both sides )
x = 3
Sarah and Emily ran a 324m race. If Sarah ran it in 61.3 seconds and Emily ran it in 60.4 seconds, how much faster was Emily than Sarah? Round to the nearest hundredth and give your answer in meters per second.
=======================================================
Work Shown:
Distance = rate*time
rate = distance/time
----------------
For Sarah, she runs 324 m in 61.3 seconds. Her speed is:
rate = distance/time
rate = (324 m)/(61.3 sec)
rate = (324/61.3) meters per second
rate = 5.28548 meters per second approximately
----------------
Repeat the same set of steps for Emily
rate = distance/time
rate = (324 m)/(60.4 sec)
rate = (324/60.4) meters per second
rate = 5.36423 meters per second approximately
----------------
The last thing to do is subtract the results we got
5.36423 - 5.28548 = 0.07875
This then rounds to 0.08 meters per second when rounding to two decimal places.

There are 144 people in an audience. The ratio of adults to children is 5 to 3. How many children are in the audience.
Answer:
In the audience, there are 90 adults and 54 children
Step-by-step explanation:
If we have 5 adults for every 3 children, we would continue this pattern by saying we have 10 adults for every 6 children, 15 adults for every 9 children, and so on.
We can express this situation into an equation by saying 5x + 3x = 144
8x = 144
x = 18
So now we know there are 5(18) = 90 adults for every 3(18) = 54 children
In the audience, there are 90 adults and 54 children

6. Carla runs 3 miles in 30 minutes.
Find the number of miles Carla runs each minute. Show your work using mathematics.
Find the number of minutes Carla runs for each mile. Show your work using mathematics.
Answer:
Carla ran 0.1 miles per minute.
Step-by-step explanation:
To solve this, we need to use the distance formula.
The formula is d=rt, where d is the distance traveled, r is the rate in which the distance is traveled, and t is the amount of time it took to go that distance. So lets plug it all in.
d=rt
3=(r)(30)
Now, we need to do the inverse of multiplying 30 to both sides, which would be the same as dividing by 30 on both sides.
3/30=(r)(30/30)
0.1=r
The rate is 0.1. Carla ran 0.1 miles per minute.
