The closest options provided are c. 0.765 or d. 0.798.
The question involves determining the critical value for the linear correlation coefficient for a sample with 10 pairs of values at a 0.01 significance level. Since the sample size is 10, the degrees of freedom (df) would be calculated as n - 2, which equals 8 (10 - 2 = 8). According to the provided studies and tables of critical values for determining the significance of a correlation coefficient, we reference a critical values table specific to our degrees of freedom and significance level.
At a 0.01 significance level and with 8 degrees of freedom, the corresponding critical value would typically be found in a statistical table designed for this purpose. However, based on the example given in the context, which is using a table with a standard significance level of α = 0.05, we can infer that the critical value for α = 0.01 would be higher, as the significance level is more stringent. None of the provided options (a. 0.684, b. 0.632, c. 0.765, d. 0.798) directly match the information given, but option c. 0.765 or d. 0.798 would typically be closer to a critical value at an α = 0.01 level with 8 degrees of freedom.

The sum of the areas of the two shaded sectors is 36 π units²
What are sectors in a circle?A sector is said to be a part of a circle made of the arc of the circle along with its two radii.
Given that a circle, with central angle 80° and the radius is 9 units
So, area of a sector = θ/360° x π x radius², where θ = central angle
Since, both the sectors are vertically opposite to each other so will same areas,
Therefore, the area of the two shaded sectors,
= 2θ/360° x π x radius²
= 2·80/360 × π × 9²
= 4/9 × π × 81
= 36π
Hence, the sum of the areas of the two shaded sectors is 36 π units²

Which of the following points is on the circle given
by the equation (x − 5)2 + (y + 3)2 = 25?
A. (5, −3)
B. (8, −6)
C. (2, 1)
D. (4, −8)
Final answer:
The correct point that lies on the circle defined by the equation (x − 5)² + (y + 3)² = 25 is point C (2, 1), as substituting these values into the equation results in 25, which matches the right side of the equation. Thus, option C is correct.
Explanation:
To find which point is on the circle given by the equation (x − 5)² + (y + 3)² = 25, you can plug the x and y values from each option into the equation and see if it holds.
For point A (5, − 3), the equation becomes (5 − 5)² + (− 3 + 3)², which simplifies to 0 + 0 = 0. This is not equal to 25, so point A is not on the circle.
For point B (8, − 6), the equation becomes (8 − 5)² + (− 6 + 3)², which simplifies to 9 + 9 = 18. This is not equal to 25, so point B is not on the circle.
For point C (2, 1), the equation becomes (2 − 5)² + (1 + 3)², which simplifies to 9 + 16 = 25. This is equal to 25, so point C is on the circle.
For point D (4, − 8), the equation becomes (4 − 5)² + (− 8 + 3)², which simplifies to 1 + 25 = 26. This is not equal to 25, so point D is not on the circle.
The correct answer is point C (2, 1), as it satisfies the equation of the circle.

Ms. Lanigan rolls a fair die 300
times. How many times does she roll an even
number, theoretically and experimentally?
Should be around 150 as 3/6 of the numbers on a die are even so thats 1/2 and 300x(1/5) or just 300x0.5 or just 300/2 equals to 150
Theoretically, it would be 150 times that it rolls even. For half of the dice's sides being even and an equal chance of it landing on any of them.
Experimentally, it could be anything between 0-300, although after so many trails in it, it would be extremely likely that it would be near 150.
If it was only 10 trials of instance it would likely have a greater margin of difference compared to the theoretical probability.

While driving to the store, your vehicle traveled 30 miles. While you we traveling, your vehicle traveled at an average speed of 15 miles per hour due to traffic. How long did it take you to get to the store? Calculating Time.
Whoever answers correctly gets marked brainliest :)
Answer:
2 hours
Step-by-step explanation:
30 miles/x hours = 15 miles/1 hour
30 = 15x
x = 2 hours
To find the time it took to get to the store, divide the distance traveled (30 miles) by the average speed (15 mph), which results in 2 hours. Thus, the trip took 2 hours.
To calculate the time it took to get to the store, we can use the formula time = distance ÷ speed. In this case, the vehicle traveled 30 miles at an average speed of 15 miles per hour. Therefore, the time can be calculated as follows:
Time = 30 miles ÷ 15 miles per hour = 2 hours.
So, it took 2 hours to get to the store.

Consider the quadrilateral below. What is the measure of angle Z
A:24
B:58
C:68
D:112
Answer:
Option C
Step-by-step explanation:
If angle w is 112, angle x has to also be 112
so 112+112=224
all of the angles summed up has to 360, so you subtract 360-224
which equals 136
then divide by 2 and you get 68
Hopefully this makes sense
Answer:
The answer is C: 68
Step-by-step explanation:
The trapezoid has a total amount of 360 degrees.
W = 112 degrees.
W and X are congruent so X also equals 112
SO if you add them together, it is equal to 224.
Subtract from 360 and 136 is left.
Divide by 2 because there is Z and Y(2 angles left) which are also congruent.
This gives the angles measurements of 68 for both Z and Y

Final answer:
The phrase 'the quotient of 12 and the product of 3 and 4' translates to the algebraic expression 12 ÷ (3 × 4), which simplifies to 1.
Explanation:
To translate the given phrase into an algebraic expression, we need to understand the terms used. The phrase is 'the quotient of 12 and the product of 3 and 4'. A 'quotient' is the result of division, and a 'product' is the result of multiplication. First, let's find the product of 3 and 4, which is 3 × 4. This equals 12. Now, we take the quotient of 12 by that product, which means we divide 12 by 12. So, the algebraic expression is 12 ÷ (3 × 4).
When we simplify this expression, since 3 × 4 equals 12, and 12 divided by 12 is 1, the expression simplifies to 1. Therefore, the simplified algebraic expression for the phrase 'the quotient of 12 and the product of 3 and 4' is 1.

The length of a rectangle is 4 feet less than 3 times its width. The perimeter of the rectangle
is 54 feet. Which equation can be used to find the width (w) of the rectangle?
Final answer:
To find the width (w) of the rectangle, set up an equation using the given information and the formula for the perimeter of a rectangle. Solve the equation to find the width.
Explanation:
To find the width (w) of the rectangle, we can set up an equation based on the given information and the formula for the perimeter of a rectangle. Let's start by assigning variables: let w be the width of the rectangle and let l be the length of the rectangle. According to the problem, the length of the rectangle is 4 feet less than 3 times its width. So we have the equation l = 3w - 4. The perimeter of a rectangle is given by the formula P = 2(l + w), where P is the perimeter. Since the perimeter is given as 54 feet, we have the equation 54 = 2(l + w). We can substitute the expression for l from the first equation into the second equation: 54 = 2((3w - 4) + w). Simplifying this equation will allow us to solve for the width (w) of the rectangle.

What is Percentage?Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
Percentage is usually denoted by the symbol '%'.
Given that,
Amount you invested at the age of 40 = $20,000
You will receive payments at the age of 50.
Amount withdrawn at the age of 47 = $7500
IRS charges 10% if you withdraw before you are 59.5.
Since your age is 47, you have to pay 10% IRS fees.
IRS fees = 10% of 7500
