You randomly sample 8 graduate students from an NYU event. 5 of the 8 exhibit higher IQ’s than the median of the general population. The probability of obtaining this result by chance (if those graduate students do not differ in IQ from the general population) is
Answer:
The probability that five of the eight students exhibit an higher IQ than the median of the general population is 0.21875
Step-by-step explanation:
The given parameters are;
The number of students in the sample, n = 8
The number of the students, x, that exhibit higher IQ's than the median = 5
The probability of obtaining the given result by chance is given as follows;
P(x) = n!/((n - x)!x!) × pˣ × qⁿ⁻ˣ
The probability that a student exhibit higher IQ's than the median = 0.5 = p
Similarly, we have, the probability that a student exhibit lower IQ's than the median = 0.5 = q
Substituting the known values, gives;
P(5) = (8!/((8 - 5)!×5!)) × 0.5^(5) × 0.5^(8 - 5) = 0.21875
Therefor, the probability that 5 of the 8 students exhibit an higher IQ than the median of the general population, P(5) = 0.21875.

Which rectangular equation is formed by eliminating the parameter?
y = t^3
x = t + 5
Given :
Two equations :
y = t³
x = t + 5
To Find :
Rectangular equation formed by eliminating the parameter.
Solution :
Putting value of t from second equation to first equation.
We get :
[tex]y = ( x-5)^3[/tex]
Also, t from equation first :
[tex]t = \sqrt[3]{y}[/tex]
Putting the value of t and equation two, we get :
[tex]x = \sqrt[3]{y}+5[/tex]
Therefore, rectangular equation is formed by eliminating the parameter is :
y = ( x - 5)³ and x = ∛y + 5 .
The rectangular equation is y = (x - 5)³ which is obtained from the parametric equations y = t³ and x = t + 5 option (3) y = (x - 5)³ is correct.
What are parametric equations?A parametric equation in mathematics specifies a set of numbers as functions of one or more independent variables known as parameters.
The options are:
y = (x + 5)³x = (y + 5)³y = (x - 5)³y = (x - 5)²It is given that:The parametric equations are:
y = t³
x = t + 5
From the second equation that is x = t + 5
Take the value of t and plug in the equation y = t³:
t = x - 5
y = (x - 5)³
The above equation represents a cubic equation.
Thus, the rectangular equation is y = (x - 5)³ which is obtained from the parametric equations y = t³ and x = t + 5 option (3) y = (x - 5)³ is correct.

Consider the function f(x) = 3x - 2 and the function g(x), which is represented by the table below. Which of the following statements about f(x) and g(x) is true? Select all that apply.
1. The slope of f(x) is smaller than the slope of g(x)
2. The lines represented by f(x) and g(x) are parallel.
3. The line represented by f(x) crosses the x-axis to the right of the line represented by g(x).
4. The y-intercept of f(x) is smaller than the y-intercept of g(x).
5. The values of f(x) and g(x) are the same at x = 3
Answer:
4. 5. 3. are correct im pretty sure
Step-by-step explanation:
Statements 1, 2, and 3 about f(x) and g(x) are "true".
What are the functions?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
Consider the function f(x) = 3x - 2 and the function g(x), which is represented by the table below.
x : 1 3 5 7 9
g(x): 3 7 11 15 19
Here the slope of the function g(x) is 2.
This means statements 1 and 2 are false because slopes are different.
To compare the position of the lines at the x-axis, you can evaluate the function at x=0. f(0) = 3×0 - 2 = -2 and g(0) = -1.
Since g(0) is less than f(0), the line represented by g(x) crosses the x-axis to the right of the line represented by f(x). So, statement 3 is true.
The y-intercept of f(x) is -2, while the y-intercept of g(x) is 1. So, statement 4 is true.
To compare the values of f(x) and g(x) at x=3, you can evaluate the functions at x=3. f(3) = 3×3 - 2 = 7 and g(3) = 7. So, the values of f(x) and g(x) are the same at x=3. So, statement 5 is true.
Therefore, the true statements are 2, 3, and 4.

45 5
Answer:
9:1, 18:2, 27:3, 36:4, 45:5 or 1,2,3,4,5
Step-by-step explanation:
This is the answer because:
1) We can see that eah ratio is being multiplied with the next number. We can say this because 9 x 2 = 18 and 1 x 2 = 2 which is 18:2 just like that 9 x 3 = 27 and 1 x 3 = 3 which makes the ratio 27:3.
2) If we keep on doing this, 9 x 4 = 36 and 1 x 4 = 4 which makes the ratio 36:4.
Therefore, the answer is 4.

During a period of time a reservoir is drained for 2 hours per day 3 times per week. Each time 12 gallons per minute are drained. What integer represents the change in the number of gallons drained from the reservoir each week?
Answer:
The integer representing the change is -43,200 gallons
Step-by-step explanation:
Here, we want to get the integer that represents the change in the number of gallons drained from the reservoir each week
Total number of hours per week would be 2 * 3 = 6 hours ;
6 hours is same as 6 * 60 = 3600 minutes
in a minute 12 gallons are drained
In 3600 minutes, the number of gallons drained would be;
3600 * 12 = 43,200 gallons are drained

A small rectangle has a width of 4 feet and a length of 10 feet. A larger, similar rectangle has a length of 12 feet. What is the perimeter of the larger rectangle?
Answer: 33.6 feet
Step-by-step explanation:
Since the small rectangle has a width of 4 feet and a length of 10 feet. It simply means that the length is 2.5 times the width.
A larger, similar rectangle has a length of 12 feet. The width will be:
= 12 / 2.5
= 4.8 feet
The perimeter of the larger rectangle will then be:
= 2(Length + Width)
= 2(12 + 4.8)
= 2 × 16.8
= 33.6 feet

Brandy only has $23 in cash to spend on drinks, and the concession stand charges $3.75
for a drink. If x represents the number of drinks purchased, and y is the amount of money
spent on drinks, what is the range in this situation?
Answer:
{0, 3.75, 7.5, 11.25, 15, 18.75, 22.5}
Step-by-step explanation:
Since the values in this function cannot go on infinitely this is a discrete funciton.
Its basically asking how much he can spend on drinks with 23$ if they are each 3.75$, this means that he can buy at most 6 drinks. Imagine a disctrete graph with a point on every value he spends per drink, (0,0) (1 , 3.75) (2 , 7.5) etc.
As our bright fellow shadow188 has stated, y is the range or the output so you list the possible outputs for the range in bracets.
I hope you found this helpful, ik its a little late.
The required range will be $3.75 ≤ y ≤ $23 for the function.
Given that,
Brandy only has $23 in cash to spend on drinks, and the concession stand charges $3.75 for a drink.
x represents the number of drinks purchased, and y is the amount of money spent on drinks, what is the range in this situation is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
Let the x be the cost of the drink and y be the total amount of money spent,
Since there are concession stand charges of $3.75 also.
So the minimum charge will be $3.75 whether bought the drink or not, and Brandy has $23 to spend on drinks so the maximum will be $23.
So, the range can be given as $3.75 ≤ y ≤ $23.
Thus, the required range will be $3.75 ≤ y ≤ $23 for the function.

A restuarant bill before tax is $63.50, if the sales tax is 7% and a 18% tip was added what is the total cost of the meal
Answer:
$79.375
Step-by-step explanation:
Given that:
Bill before tax = $63.50
Tax = 7%
Tip added = 18%
Hence,
Tax = 7% of bill before tax
Tax amount = 0.07 * 63.50
Tax amount = $4.445
Tip amount = 0.18 * 63.50
Tip amount = $11.43
Total meal cost :
Before tax cost + tax amount + tip amount
$(63.50 + 4.445 + 11.43) = $79.375

What is f(−1) for the function given? f(x)=x2−3x+8
Answer:
12
Step-by-step explanation:
I am assuming you are asking for f(x)=x^2-3x+8? You plug (-1) in for all portions of x. This means you get (-1)^2-3(-1)+8. (-1)^2 is simply 1 because -1 x -1=1. 3*-1 is -3. This makes the equation 1 - (-3) + 8. The middle section simplifies down to +3 making it 1+3+8, or 12.
