For the following sample of n 5 10 scores:
a. Assume that the scores are measurements of a discrete variable and find the median.
b. Assume that the scores are measurements of a continuous variable and find the median by locating the precise midpoint of the distribution.
Scores: 2, 3, 4, 4, 5, 5, 5, 6, 6, 7
Answer:
Step-by-step explanation:
Given that:
scores = 2, 3, 4, 4, 5, 5, 5, 6, 6, 7
Since the scores are already in ascending order; then the median which is the middle number will be:
median = (5th term + 6 term)/2
median = (5+5)/2
median = 10/2
meian = 5
b)
Use the cumulative percentage table
X frequency cumulative frequency cumulative percentage
2 1 1 10%
3 1 2 20%
4 2 4 40%
5 3 7 70%
6 2 9 90%
7 1 10 100%
fraction = the no. required to reach 50%/ no. in that interval
= 1/3
Since we have a total of 4 boxes when we reach the value of 4.5
The median of the continuous variable = 4.5 + (1/3)
The median of the continuous variable = 4.833
The median of the continuous variable ≅ 5
Answer:
Step-by-step explanation:
Given that:
scores = 2, 3, 4, 4, 5, 5, 5, 6, 6, 7
Since the scores are already in ascending order; then the median which is the middle number will be:
median = (5th term + 6 term)/2
median = (5+5)/2
median = 10/2
median = 5

Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5/3x-4/3x-1=8
5 /3 x+ −4 /3 x+−1=8
(5 /3 x+ −4 /3 x)+ (−1) =8 (Combine Like Terms)
1/3x-1 =8
1/3x=9
(1/3 x) x 3 = 3 x 9
x=27
Answer: x=27
Step-by-step explanation: if you want to Solve for X, you have to by simplify both sides of the equation, then isolating the variable.

93 = 2x + 18 + x = 3x + 18
Answer:
x=25
Step-by-step explanation:
To get this answer you need to simplify everything that you can. So basically, first you would combine 2x and x to get 3x+18. Note that you don't need to use the second part of the equation if you don't want to. Same with the third because they are all equal. Noting this, you subtract 18 from both sides of the equation leaving you with 75= 3x. Proceed to divide both sides by three and end with the answer 25=x.

Answer: 11
Explanation:
*difference* is the answer you get when subtracting,
so, 16-9
you get 7,
*quotient* is the answer you get when dividing,
so, 12/3
you get 4,
finally, you add 4+7
which is 11

A tank contains 250 liters of fluid in which 20 grams of salt is dissolved. Brine containing 1 gram of salt per liter is then pumped into the tank at a rate of 5 L/min; the well-mixed solution is pumped out at the same rate. Find the number A(t) of grams of salt in the tank at time t.
Answer:
[tex]A(t)=250-230e^{-\frac{t}{50} }[/tex]
Step-by-step explanation:
A(t) is the amount of salt in the tank at time t.
dA / dt = rate of salt flowing into the tank - rate of salt going out of the tank
dA / dt = (1 g/L)*(5 L/min) - (A(t)/250 g/L) * (5L/min)
dA / dt = 5 g/min - (A(t) / 50) g/min
[tex]\frac{dA}{dt}+\frac{A(t)}{50} = 5\\\\The\ integrating\ factor(IF)= e^{\int\limits \frac{1}{50}dt }=e^{\frac{t}{50} }\\\\Multiplying\ through\ by\ the\ I.F:\\\\\frac{dA}{dt}*e^{\frac{t}{50} }+\frac{A(t)}{50}*e^{\frac{t}{50} } = 5*e^{\frac{t}{50} }\\\\Integrating \ both \ sides:\\\\\int\limits[ \frac{dA}{dt}*e^{\frac{t}{50} }+\frac{A(t)}{50}*e^{\frac{t}{50} }] dt=\int\limits 5e^{\frac{t}{50} } dt\\\\A(t)e^{\frac{t}{50} } =\int\limits 5e^{\frac{t}{50} } dt\\\\[/tex]
[tex]A(t)e^{\frac{t}{50} } =250e^{\frac{t}{50} }+C\\\\A(t)=250+Ce^{-\frac{t}{50} }\\\\But\ A(0) = 20\\\\20=250+Ce^{-\frac{0}{50} }\\\\C+250=20\\\\C=-230\\\\A(t)=250-230e^{-\frac{t}{50} }[/tex]

Step-by-step explanation:
Deandre is driving to Denver. Suppose that the distance to his destination (in miles) is a linear function of his total driving time (in minutes). Deandre has miles to his destination after minutes of driving, and he has miles to his destination after minutes of driving. How many miles will he have to his destination after minutes of driving
Answer and explanation:
If distance to his destination(in miles) is a function of his minutes of driving(time) then the formula can suffice:
Distance = Speed × Time
if distance is 5 miles to his destination
Speed is 1 mile/hr
Time taken is 4 hrs or 240 minutes
Then Deandre would have 1 mile left to reach his destination after 240 minutes
Let g be the function given by g(x)=√ 1−sin2x. Which of the following statements could be false on the interval 0≤x≤π ?
The statement that could be false on the interval is if x is greater than π/2
Given the function g(x)=√ 1−sin2x
We are to get the value of x that will make the function not exist. For the function not to exist, hence:
sin2x> 1
Solve the expression for x
2x > arcsin(1)
2x > π
x > π/2
This shows that the statement that could be false on the interval is if x is greater than π/2
