an instructor wants to study the variance among two 30-second trials of a tennis wall volley test. what statistic will the instructor probably calculate?
Answers
The tennis wall volley test has two 30-second trials, and a teacher is interested in analyzing the variation between them. The instructor will most likely determine the "intraclass correlation coefficient" statistic.
Explain the term intraclass correlation coefficient?An indicator of the validity of the ratings for clusters is the intraclass correlation coefficient, abbreviated ICC.
Data that is grouped together is referred to as a cluster. Instead than comparing two independent classes of data, ICC is used to detect correlations within a specific class of data.As was already noted, Pearson's r is the most often utilized correlation coefficient. When there are just one or two significant pairs from just one or two raters, Pearson's correlation coefficient is typically employed to measure inter-rater reliability. However, this intraclass correlation coefficient ought to be utilized if there are more pairs.A tennis wall volley test has two 30-second trials, and a teacher is interested in analyzing the variation between them.

Latrell wants to buy a car but only has half as much money as he needs. If Latrell deposits the money into a savings account that earns 6.3% interest compounded quarterly, how long will it take for his money to double?
Answers
The number of years will take for his money to double is 10.87 years
Let's assume the amount of money Latrell needs to buy the car "P". Since Latrell only has half of that amount, we can say that he has 0.5P. We want to find out how long it will take for Latrell's money to double, so we want to solve for the time "t" in years.
We can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where:
A = final amount of money (in this case, 2P, since we want to find out how long it takes for Latrell's money to double)
P = initial amount of money (0.5P, since that's what Latrell has now)
r = annual interest rate (6.3%)
n = number of times the interest is compounded per year (4, since it's compounded quarterly)
t = time (in years)
Substituting in the values we know, we get:
2P = 0.5P(1 + 0.063/4)^(4t)
Simplifying, we can divide both sides by 0.5P:
4 = (1 + 0.063/4)^(4t)
Taking the natural logarithm of both sides, we get:
ln(4) = 4t ln(1 + 0.063/4)
Dividing both sides by 4 ln(1 + 0.063/4), we get:
t = ln(4) / (4 ln(1 + 0.063/4))
t ≈ 10.87 years

Enter the difference between the rates of change for these two functions.
Answers
========================================
Explanation:
Let's find the slope of the graphed line
Use the slope formula on two points from the diagonal line. I'll pick the two points (-1,-2) and (0,2) to get
m = (y2-y1)/(x2-x1)
m = (2-(-2))/(0-(-1))
m = (2+2)/(0+1)
m = 4/1
m = 4
The slope of the graph is 4. This is the same as the rate of change for this graph.
-----------------
Repeat those steps for the data table
I'll pick the first two rows (0,-6) and (2,-2)
m = (y2-y1)/(x2-x1)
m = (-2-(-6))/(2-0)
m = (-2+6)/(2-0)
m = 4/2
m = 2
The slope, or rate of change, here is 2
-----------------
Now subtract the two slopes: 4-2 = 2
The answer is 2.
The difference between the rates of change for these two functions
is 2.
What is slope?The slope is the rate of change of the y-axis with respect to the x-axis.
The equation of a line in slope-intercept form is y = mx + b, where
slope = m and y-intercept = b.
We know the greater the absolute value of a slope is the more steeper is its graph or the rate of change is large.
We know the slope(m) between the two points (x₁, y₁) and (x₂, y₂) is given by, m = (y₂ - y₁)/(x₂ - x₁).
The two coordinate points of the graph of the line are (0, 2) and (- 1, - 2).
slope(m₁) = (- 2 - 2)/(- 1 - 0).
slope(m₁) = 4.
Slope(m₂) = (- 2 + 6)/(2 - 0).
slope(m₂) = 2.
Therefore, The difference between the rate of change of the two functions is, m₁ - m₂ = 4 - 2 = 2.

x + 3y = 7

Answers
Answer:
y = 1
x = 4
Step-by-step explanation:
x + 3y = 7 → ( 1 )
2x - y = 7 → ( 2 )
First, let us make x the subject in equation ( 1 ).
x = 7 - 3y → ( 3 )
Let us find the value of y.
For that let us take equation (1) & replace x with ( 7 - 3y ).
2x - y = 7
2 ( 7 - 3y ) - y = 7
Solve the brackets.
14 - 6y - y = 7
Combine like terms.
14 - 7y = 7
Subtract 14 from both sides.
-7y = 7 - 14
-7y = -7
Divide both sides by -7.
y = 1
Let us find value of x
For that let us take equation (3) & replace y with 1.
x = 7 - 3y
x = 7 - 3 × 1
x = 7 - 3

the cube root of 64 is 4. how much larger is the cube root of 65.1? estimate using the linear approximation.
Answers
The exact difference is 0.022916
Given that the cube root of 64 is 4
We need to find how much larger is the cube root of 65.1 using the linear approximation.
Linear approximations:
They are ways to define a line tangent to a curve. At a particular range near the tangent point, the line can serve as an approximation for the function. However, linear approximations are determined through a combination of differentiation.
Here, when the tangent point is defined at x=a
then the linear approximation of a function is defined as f(x) ≈ f(a)+f′(a)(x−a)
Consider a = 64 f(x) = x^(1/3)
f'(x) = 1/3 x ^(-2/3)
So linear approximation is f(x) = 4 + 1/3 (64)^(-2/3) * (x-64)
x = 65.1
f(65.1) = 4 + 1/3 (64)^(-2/3) * (65.1 - 64)
f(65.1) - 4 = 1/3 1.1 (64)^(-2/3) = 1/3 * 1.1 * 1/16 = 1.1 / 48 = 0.0229

What is quotient rule?
A technique for determining the derivative of a function that is the ratio of two differentiable functions in calculus is known as the quotient rule. Let h(x) = f(x) / g(x), where g(x) ≠ 0 and f and g are both differentiable.
Suppose f(x) and g(x) are the function in variable x.
Is we take the derivative of f(x) and g(x) then both the functions are differentiable.
So, if we apply the quotient rule the functions are differentiable.
And derivative exists for all values of x for both functions f(x) and g(x).
Hence, using the quotient rule, the derivative exists for all values of x for every function.
