A researcher is studying psychological factors in artistic achievement among teenage boys. One variable he is particularly interested in is perseverance.
1. What information does a measure of variability for the variable perseverance convey?
2. What is the most common value for the variable perseverance among teenage boys?
3. How spread out are the values for perseverance among teenage boys?
4. What is the central tendency for the variable perseverance among teenage boys?
5. What is the average value for the variable perseverance among teenage boys?
Answer:
How spread out are the values for perseverance among teenage boys?
Step-by-step explanation:
1. What is the most common value for the variable perseverance among teenage boys? - This deals with MODE. Hence, this option is not correct because the problem does not deal with a specific value of the perseverance variable but about the variability of the perseverance variable
2. What is the central tendency for the variable perseverance among teenage boys? - This deals with the MEDIAN. However, since the problem is about determining dispersion, and not a central tendency, it is incorrect.
3. What is the average value for the variable perseverance among teenage boys? - This deals with the MEAN. Hence, it is not correct either.
However, since the given situation deals with a measure of variability for the variable perseverance conveys, the correct answer is "How spread out are the values for perseverance among teenage boys?" Because it measures how far are the observation away from the center.
If the numerator of a fraction is increased by 3, the fraction becomes 3/4. If the denominator is decreased by 7, the fraction becomes 1.
What is the numerator of the fraction?
A. 2
B. 9
C. 16
I will give brainlist to the one who gets the answer right....
Answer:
B
Step-by-step explanation:
Assuming the denominator is 16 (to fit with the second part), 9+3 is 12 and 12/16 is 3/4.
If we take 7 from 16 we also get 9, which is thus 1.

2. Maya has a piece of fabric in the shape of a parallelogram. Its height is 12 feet and its base is 18 feet. She cuts the fabric into four equal parallelograms by cutting the base and the height in half. What is the area of each new parallelogram?
Answer:
54 square feet each
Step-by-step explanation:
So she has a parallelogram, 12 feet high and 18 feet long. She cuts them into fours, which is basically just cutting each number in half. 12÷2 is 6. 18÷2 is 9. Now each four parallelograms all have the measurements of 6 feet high and 9 feet wide. To find area, you would multiply and the base times height. 6 x 9 gives you 54 square feet.

A rolling pin has a diameter of 5 inches. If Lin rolled across the table and it made 35 rotations how far did it travel?
Answer:
2.22 rotations
Step-by-step explanation:
First, have to multiply the diameter by Pi. 5 * π = 15.7
15.7 is the circumference because the formula for circumference is d * π = c (diameter=d, circumference=c)
Next, 35/15.7 is 2.22.
You divide the 35 by 15.7 because if 15.7 inches is one rotation, then you want to see how many rotations fit into 35.
The rolling pin travels a distance of 549.5 inches in 35 rotations.
What is a sphere?A sphere has a spherical, symmetrical form. It is a three-dimensional solid with equal distances between each surface point and the center.
Given that, the diameter of the rolling pin is 5 inches.
The circumference of the rolling pin is:
5π
= 5×3.14
=15.7
Therefore, the rolling pin covers 15.7 inches in one rotation.
1 rotation = 15.7 inches
35 rotation = 35 ×15.7 inches
35 rotation = 549.5 inches
Hence, the rolling pin travels a distance of 549.5 inches in 35 rotations.

Find the value of x for which the lines rand s are parallel.
Answer:
x = 12
Step-by-step explanation:
<1 and the 142-deg angle are vertical, so m<1 = 142 deg
The angle measuring 3x + 2 and <1 are same-side interior angles. If the lines are parallel, then those two angles are supplementary.
3x + 2 + 142 = 180
3x + 144 = 180
3x = 36
x = 12
In the given figure, x = 30°. What's the property of parallel lines used to find x? Question 6 options: A) Angles at the same side of the transversal are supplementary. B) Alternate interior angles are congruent. C) Alternate exterior angles are congruent. D) Corresponding angles are congruent.
Answer:
Option (C)
Step-by-step explanation:
Option A.
"Angles at the same side of the transversal are supplementary".
But the angles given are not on the same side of the transversal.
Option B.
"Alternate interior angle are congruent"
These angles are not the interior angles.
Option C.
"Alternate exterior angles are congruent"
Both the angles are alternate and exterior angles.
Therefore, Option (C) is the correct option.
Option D.
"Corresponding angles are congruent"
These angles are not the corresponding angles.

This integral is obtained using disk method. Each disk has a volume of V = πr²t, so the radius is r = x.
The region is 0 ≤ y ≤ x, 0 ≤ x ≤ 1.
Revolved around the x-axis, the resulting shape is a cone.
If the shape were a paraboloid, the integral would have been:
π ∫₀¹ (x²)² dx
π ∫₀¹ x⁴ dx

A remote ranch has a cylindrical water storage tank. It has a vertical central axis, a diameter of 16 ft, the sides are 5 ft high, and it is full to the brim. The depth of this water is 4 ft. How much work (in ft-lb) would be required to pump all of the water over the upper rim? (Use the fact that water weighs 62.5 lb/ft3. Round your answer to the nearest integer.)
Answer and Step-by-step explanation:
Given: diameter = 16ft height = 5 ft. Depth = 4ft
Work =?
As we know that work = force x distance
W= distance x density x volume
W= ʃ04 (5-y) 62.5x ∏ (d/2)2dy (area = ∏r2 , r= d/2)
= 62.5 ʃ04 (5-y) ∏ (4y) dy
=62.5∏ ʃ04 (5-y) 4ydy
=62.5∏ ʃ04 20y-4y2dy
=62.5∏ |20y2/2 – 4y3/3|04
=62.5∏ |74.66|
=14659ft.lbs (approximately)
The work (in ft-lb) that would be required to pump all of the water over the upper rim is :
Given: Diameter = 16ft Height = 5 ft. Depth = 4ftWork =?
Formula:work = force x distance
W= distance x density x volume
W= ʃ04 (5-y) 62.5x ∏ (d/2)2dy (area = ∏r2 , r= d/2)
W = 62.5 ʃ04 (5-y) ∏ (4y) dy
W =62.5∏ ʃ04 (5-y) 4ydy
W =62.5∏ ʃ04 20y-4y2dy
W =62.5∏ |20y2/2 – 4y3/3|04
W =62.5∏ |74.66|
W =14659ft.lbs (approximately)
The work (in ft-lb) that would be required to pump all of the water over the upper rim is 14659ft.lbs
