The average mark of candidates in an aptitude test was 128.5 with a standard deviation of 8.2.Three scores extracted from the test 148,102,152,what is the average of the extracted scores that are extreme values(outlier).​

Answer:

⅜ x + ¹/₁₂ sin(6x) + ¹/₉₆ sin(12x) + C

Step-by-step explanation:

∫ cos⁴(3x) dx

Use power reduction formula:

⅛ ∫ (3 + 4cos(6x) + cos(12x)) dx

⅜ ∫ dx + ½ ∫ cos(6x) dx + ⅛ ∫ cos(12x) dx

⅜ ∫ dx + ¹/₁₂ ∫ 6 cos(6x) dx + ¹/₉₆ ∫ 12 cos(12x) dx

⅜ x + ¹/₁₂ sin(6x) + ¹/₉₆ sin(12x) + C

We have been given that on May 22, 1960, an earthquake in Chile measured 9.5 on the Richter scale. On February 27, 2010, another earthquake in Chile measured 8.8 on the Richter scale.

We will use Richter scale formula to compare the intensities of the two earthquakes.

[tex]R=\log(I)[/tex], where

R = Richter scale value,

I = Intensity

Upon substituting our given values, we will get two equations.

[tex]9.5=\log(I_1)...(1)[/tex]

[tex]8.8=\log(I_2)...(2)[/tex]

Upon subtracting equation (2) from equation (1), we will get:

[tex]9.5-8.8=\log(I_1)-\log(I_2)[/tex]

[tex]0.7=\log(I_1)-\log(I_2)[/tex]

Using log property [tex]\log(a)-\log(b)=\log(\frac{a}{b})[/tex], we will get:

[tex]0.7=\log(\frac{I_1}{I_2})[/tex]

[tex]\log(\frac{I_1}{I_2})=0.7[/tex]

[tex]\frac{I_1}{I_2}=10^{0.7}[/tex]

[tex]\frac{I_1}{I_2}=5.011872336[/tex]

Upon rounding our answer to the nearest whole number, we will get:

[tex]\frac{I_1}{I_2}\approx 5[/tex]

Therefore, the earthquake in 1960 had about  5 times the intensity as the earthquake in 2010.

We have been given that a bicycle wheel has a circumference of 66 inches. We are asked to find the radius of the wheel.

We will use circumference of circle formula to solve our given problem.

[tex]\text{Circumference of circle}=2\pi r[/tex], where r represents radius if circle.

Upon substituting our given values, we will get:

[tex]66=2\cdot 3.14\cdot r[/tex]

[tex]66=6.28\cdot r[/tex]

[tex]6.28\cdot r=66[/tex]

[tex]\frac{6.28\cdot r}{6.28}=\frac{66}{6.28}[/tex]

[tex]r=10.509554[/tex]

Upon rounding to nearest hundredths, we will get:

[tex]r\approx 10.51[/tex]

Therefore, the radius of the wheel is approximately 10.51 inches.

Step-by-step explanation:

symmetric distribution  usually be a bell shape distribution .

most likely the median = mean = 60

The required value of 60 could be the median of the distribution. Option B is correct.

The mean of the values is the ratio of the total sum of values to the number of values.

When a dataset is ordered, the median is the value that is exactly in the middle. It is a measure of central tendency that distinguishes between the lowest and top 50% of data.

Here,
The mean of a symmetric distribution is 60.
Since for the symmetric data and rational data, the mean is equal to the median,
So Mean = Median
Median = 60

Thus, the required value of 60 could be the median of the distribution.

B. l and lV

Step-by-step explanation:

The pairs of equations will never break even is Cost 35.79 n + 6,700 and Revenue 56.95 n. The correct option is D.

The break-even point is the point at which total cost and total revenue are equal, implying that your small business has no loss or gain.

To find the break-even point, we need to set the cost equation equal to the revenue equation and solve for n:

Cost = Revenue

65.16n + 1,500 = 98.75n   (for equation I)

32.59n = 1,500

n = 46.05

So the break-even point for equation I is 46.05 units.

Cost = Revenue

35.79n + 6,700 = 56.95n   (for equation II)

21.16n = 6,700

n = 316.3

For options (c) and (d), we need to compare the break-even points for equations III and IV with equations II and I, respectively.

Cost = Revenue

65.16n + 1,500 = 56.95n   (for equation IV)

8.21n = -1,500

n = -182.7

The negative value for n means that equation IV does not have a break-even point.

Cost = Revenue

35.79n + 6,700 = 98.75n   (for equation III)

62.96n = 6,700

n = 106.2

The break-even point for equation III is 106.2 units.

Therefore, the pair of equations that will never break even is (d) I and IV.

Answer:

133 Students

Step-by-step explanation:

Let the number of student in a van=v

Let the number of student in a bus=b

The senior class at Snellville rented and filled 12 vans and 14 buses with 796 students.

Therefore: 12v+14b=796

General High rented and filled 14 vans and 12 buses with 738 students.

Therefore: 14v+12b=738

We solve the two resulting equations simultaneously

12v+14b=796

14v+12b=738

Multiply equation 1 by 12 and equation 2 by 14 to eliminate b

144v+168b=9552

196v+168b=10332

Subtract

-52v=-780

Divide both sides by -52

v=15

We substitute v=15 to obtain b in any of the equations

12v+14b=796

12(15)+14b=796

14b=796-180

14b=616

Divide both sides by 14

b=44

Therefore a bus contains 44 Students and a Van contains 15 students.

Number of Students who would fill 2 buses and 3 vans

=2b+3v

=2(44)+3(15)

=133 Students

Answer:

Max will choose the wall hanging that is shaped like a trapezoid.

Step-by-step explanation:

To find the area of the trapezoid, break it into a triangle and another trapezoid. Use the formula for the area of a triangle (A=base*height*1/2) and the formula for the area of a trapezoid (A=base+base*height*1/2). The area of the trapezoid is 672 square centimeters.

To find the area of the kite, break it into two identical triangles. (There's a horizontal line between them.) Use the formula for the area of a triangle for both, then add the two areas. The area of the kite is 648 square centimeters.

Finally, we know that 672>648. Therefore, Max will choose the wall hanging that is shaped like a trapezoid.

Answer:4√(13)

Adjacent=12

Opposite=8

Hypotenuse=√((adjacent)^2+(opposite)^2)

hypotenuse=√(12^2+8^2)

Hypotenuse=√(12x12+8x8)

Hypotenuse=√(144+64)

Hypotenuse=√(208)

Hypotenuse=√(16x13)

hypotenuse=√(16) x √(13)

Hypotenuse=4 x √(13)

Hypotenuse=4√(13)

Work Shown:

In the numerator, we have 2^2*x^2, which is really just 4x^2. Replace x with 3 and we get 4*x^2 = 4*3^2 = 36.

For the denominator, xy^2, we get

x*y^2 = 3*2^2 = 12

So far we have,

[tex]\frac{2^2x^2}{xy^2} = \frac{4x^2}{xy^2} = \frac{36}{12} = 3\\\\\text{ or simply} \\\\\frac{2^2x^2}{xy^2} = 3[/tex]

when x = 3 and y = 2.

Square both sides to end up with...

[tex]\frac{2^2x^2}{xy^2} = 3\\\\\left(\frac{2^2x^2}{xy^2}\right)^2 = 3^2\\\\\left(\frac{2^2x^2}{xy^2}\right)^2 = 9[/tex]

Explanation:

We assume your question is "why is that name given to these three numbers?"

There are many names in mathematics that are given to sequences or sets of numbers having a particular characteristic. The term "Pythagorean triple" is usually reserved for three positive integers that satisfy the relation "the sum of the squares of the smaller two is equal to the square of the largest."

This relationship exists between the side lengths of a right triangle, which is the point of the Pythagorean theorem. So, integer side lengths of a right triangle constitute a "Pythagorean triple."

_____

If your question is "why do right triangle side lengths have the relationship specified by the Pythagorean theorem?", that demands a different answer. In general, the sides and angles of a triangle obey the Law of Sines and the Law of Cosines.

One of the expressions of the Law of Cosines is ...

  c² = a² +b² -2ab·cos(C)

where C is the angle opposite side c in the triangle. You may recall that the cosine of 90° is zero, so the cosine term in this equation vanishes when angle C is a right angle. The remaining equation is ...

  c² = a² +b²

This is an expression of the Pythagorean theorem, and it is true only for right triangles.

Option D: 5591.93

Step-by-step explanation:

The best way to understand this question is to apply the formula in an indirect manner;

P - Principle number, Starting Value

T - Time

I - Interest

Let us convert the interest into decimal form, such that 3.8% is shifted two decimal points to the right ⇒ 0.038. Now add 1 to this value to get ⇒ 1.038. By PEDMAS, you would first raise this value to the span of 3 years as such:

(1.038)^3 = 1.118386872.......

The final step would by to multiply the starting value (investment $) $ 5,000 by this continuing value of 1.118386872:

5,000(1.118386872) = 5591.93436 ⇒ Rounded to (About) 5591.93

Answer:D

Step-by-step explanation:

principal=p=$5000

Rate=r=3.8%

Time=n=3 years

amount=a

a=p(1+r/100)^n

a=5000(1+3.8/100)^3

a=5000(1+0.038)^3

a=5000(1.038)^3

a=5000 x 1.038 x 1.038 x 1.038

a=5591.93
