miley believes that listening to white noise can enhance verbal exam performance. she takes a random sample of college students and randomly assigns each student to one of two groups-the quiet group and the white noise group. the quiet group is asked to take a verbal exam in a completely silent classroom. the white noise group is asked to take the same exam in a classroom in which white noise is playing in the background. all students have one hour to complete the exam. miley will then compare the mean exam score for the two groups. suppose miley makes a type i error. in terms of the scenario, what would this mean?
A Type I error in this scenario would mean that Miley would conclude that the noise impacts the students when in fact it doesn't.
What are Type I errors and Type II errors?The definitions of Type I errors and Type II errors are presented as follows:
Type I: Rejection of a true null hypothesis, meaning that the null hypothesis is true, but a sample gives you enough evidence to reject it.Type II: Non-rejection of a false null hypothesis, meaning that the null hypothesis is false, but the sample does not give you enough evidence to reject it.The hypotheses tested in this problem are given as follows:
Null hypothesis: not enough evidence to conclude that there are differences in the exam scores.Alternative hypothesis: enough evidence to conclude that there are differences in the exam scores.A Type I error would mean that she rejected a true null hypothesis, meaning that Miley would conclude that the noise impacts the students when in fact it doesn't.

y = 10(1.01)
The given exponential function represents the growth in the function. The percentage of growth (increase) is 1%.
What is the exponential growth function?An exponential growth function is a function where the quantity increases slowly and after some time, it increases rapidly.
It is represented by the formula,
y = a(1 + r)ˣ
Here the term 'a' is the initial amount of the quantity, the term 'r' is the rate of increase and the term 'x' is the period.
Calculation:The given exponential function is y = 10(1.01)ˣ
Here we can write the function as
y = 10(1.01)ˣ
⇒ y = 10(1 + 0.01)ˣ
Since 1.01 > 1, it is an exponential growth function.
So, when comparing with the formula, we get the rate of increase,
r = 0.01
Converting it into fractions, we get 1/100
Then, the percentage rate of increase is 1%.

y = 7²,y + (1/2)x = 9 and 2.3 = y - 5.8x are the linear function thus option (A),(D) and (F) are correct.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
A linear function is a line in a coordinate plane with a constant slope and can be written in form of y = mx + c.
Thus the degree of x and y will be 1.
For example, y = 7² can be written as, y = 0(x) + 7² so it will be a linear line.
Another y + (1/2)x = 9 and 2.3 = y - 5.8x are can be written as y = mx + c so they will be linear functions.
Hence "the functions y = 7²,y + (1/2)x = 9 and 2.3 = y - 5.8x are the linear function".

f(4) = -4
g(4) = 2
Then:
(f×g)(4) = f(4)*f(4)
(f×g)(4) = -4*2
(f×g)(4) = -8
c) Finally we have other composition:
f( g(h(0)))
So we have 2 compositions, first we find:
h(0) = 5
f( g(h(0))) = f(g(5))
Then:
g(5) = 0
f( g(5)) = f(0)
Finally, look at the graph and you can see that f(0) = -1

This graph shows fuel consumption for a car during a test run. Three of the statements are true. Which is NOT?
Line graph. X axis labeled miles; y axis labeled gallons. Line with upward arrow extends from point where X and Y axes connect (0, 0) with one marked coordinate (73.5, 3.5).
The car used 312 gallons of gas to go nearly 75 miles.
The car used 70 gallons of gas to go 3 miles.
The car used gas at a unit rate of 21 miles per gallon.
At this rate, it would take 4 gallons of gas to travel 84 miles.
In the graph showing fuel consumption for a car during a test run the correct statement is
At this rate, it would take 4 gallons of gas to travel 84 miles.How to find the correct statementThe information given in the problem will help to find the equation of the graph in the form
y = mx + c
definition of variable to suit the problem
y = output variable = number of gallons
m = slope
x = input variable = number of miles
c = y intercept
The slope
= (3.5 - 0) / (73.5 - 0)
= 0.05
the y intercept is 0
the equation of the line is y = 0.05x
Only option the last option fits the equation as shown
number of gallons = 0.05 * number of miles
= 0.05 * 84 miles
= 4.2 gallons
= 4 gallons
hence the last option is the correct choice

Complete the equation of the line whose yyy-intercept is (0,-1)(0,−1)left parenthesis, 0, comma, minus, 1, right parenthesis and slope is 444.
The complete equation in the slope-intercept form is y = 4x-1.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
So, the equation is,
y - y₁ = m (x - x₁)
And the standard form of the slope-intercept form:
y = mx+b,
where m is the slope and b is the y-intercept.
From the question, we have
m = 4 and coordinates of b is (0, -1).
So, the equation is,
y + 1 = 4 (x - 0)
y +1 = 4x
y = 4x-1
Therefore, the equation is y = 4x-1.
