One kind of average is the mean. It is calculated by dividing the total number of values in a list of values, such as measurements or numbers, by the total number of values in the list.

Given data :

a ) Mean =

              x = [tex]\frac{\left \{ {{i=10} \atop {i=1}} \right.}{n} Xi[/tex] = 101 / 10 =  10.1 hundreds of dollars

The median is the 50th percentile To determine the location index for the median (2nd

The index is

                               i  = [tex]\frac{p}{100}[/tex] (n) = [tex]\frac{50}{100}[/tex] (10) = 5 integer

Step-by-step explanation:

after mixing 1 can of concentrate and 3 cans of water, we will have 4 cans of juice.

the volume of 1 can is (as for any cylinder or regular 3D object)

base area × height

for a cylinder the bar area is the area of a circle

pi×r²

r is the radius, which is half of the diameter.

in the picture it is not fully clear what is 2.25 in long : the diameter of the radius ?

I suspect it is the diameter.

so, the radius of our cans is 2.25/2 = 1.125 in

the volume of 1 can is

pi×1.125²×4.25

and the volume of all 4 cans of juice is then

4×pi×1.125²×4.25 = 17×3.14×1.265625 = 67.5590625 in³

Use  Pythagorean theorem a^2 + b^2 = c^2:

The peak of the mountain has a height of 14805 feet.

In this problem we find the case of an exponential function for atmospheric pressure (p), in pounds per square inch, in terms of height (x), in miles, whose expression is introduced below:

[tex]p(x) = 14.7 \cdot e^{- 0.21\cdot x}[/tex], for x ≥ 0.

If we know that p(x) = 8.164 lb / in², then the height of the peak of a mountain is:

[tex]8.164 = 14.7\cdot e^{-0.21 \cdot x}[/tex]

[tex]0.555 = e^{-0.21\cdot x}[/tex]

Then, by relationship between exponential and logarithmic functions and logarithm properties:

㏑ 0.555 = - 0.21 · x · ㏑ 1

㏑ 0.555 = - 0.21 · x

x = - (1 / 0.21) · ㏑ 0.555

x ≈ 2.804

Finally, convert miles into feet:

x = 2.804 mi × (5,280 ft / 1 mi)

x = 14805.12 ft

4. y''-y+y2=0  ->  2nd. order non-linear differential equation

The order of a differential equation is the highest derivative involved in the equation. For example, in the equation 1 + y2(d2y/dt2) + t(dy/dt) + y = et2, the highest derivative is the second derivative (d2y/dt2), so this equation is of 2nd order. Linearity is determined by whether the coefficients of each derivative are constants, or whether they depend on the function y and its derivatives. In this equation, the coefficient of the second derivative (1+y2) is not constant, so the equation is non-linear. Similarly, in equation t2(d2y/dt2)+t(dy/dt)+2y=sin t, the coefficient of the second derivative (t2) is constant, so the equation is linear.

Answer: The equation that can be used to determine the total amount in Justin's account is:

b = 50 + (12 * w)

This equation represents the total amount in Justin's account, b, after w weeks. The equation starts with the initial amount, $50, which is the amount Justin had in his account before making any deposits. Then, it adds the amount deposited each week, $12, multiplied by the number of weeks, w. This results in the total amount in the account after w weeks.

In this equation the variable "w" represents the number of weeks that have passed and "b" represents the total balance.

Step-by-step explanation:

The values of p and q are given as follows:

p = 3.5, q = 6.

Hence the factored expression is given as follows:

2(x - 1.5)(x - 2)(x + 2).

The function f(x) is divisible by 2x² - 7x + 6, which has the roots given as follows:

x = 1.5 and x = 2.

(using a quadratic equation calculator with coefficients a = 2, b = -7 and c = 6).

Hence the following relation holds true, considering the linear factors of the function:

2x³ + px² + 8x + q = 2(x - 1.5)(x - 2)(x - a).

In which a is the third root.

Hence:

2x³ + px² - 8x + q = 2(x² - 3.5x + 3)(x - a)

2x³ + px² - 8x + q = 2(x³ - x²(3.5 + a) + x(3.5a + 3) - 3a)

2x³ + px² - 8x + q = 2x³ - x²(7.5 + 2a) + x(7a + 6) - 3a.

Hence the system of equations is given as follows:

From the second equation, the value of a is given as follows:

7a = -14

a = -2

Then the value of q is given as follows:

q = -3a = 6.

The value of p is given as follows:

V = πr²h/3

Putting the given values in place,

V = 75.36 cm³

V = 75.36 cm³r = 2 cm

V = 75.36 cm³r = 2 cmπ = 3.14

Now, since we calculating for h, we can interpret the formula in the terms of h, i.e.

h = 3V/(πr²)

h = 3×75.36/(3.14×2²)

h = 226.08/12.56

h = 18 cm

Number of cycles per day = (16/Production Quantity per Cycle)

For Product C:

Number of cycles per day = (6/Production Quantity per Cycle)

For Product D:

Number of cycles per day = (14/Production Quantity per Cycle)

Using the data from the excel file, we can calculate the production quantity per cycle and the number of cycles per day.

For Product A:

Production Quantity per Cycle = 18/3.75 = 4.8

Number of cycles per day = 3.75

For Product B:

Production Quantity per Cycle = 16/2.5 = 6.4

Number of cycles per day = 2.5

For Product C:

Production Quantity per Cycle = 6/1.5 = 4

Number of cycles per day = 1.5

Answer:

Width = 3.773 inches

Length = 79.227 inches-

Step-by-step explanation:

g = 7(3w)             Eq. 1

166 = 2(g+w)       Eq. 2

g = length

w = width

From Eq, 1:

g = 21w              Eq. 3

Replacing Eq. 3 in Eq. 2

166 = 2(21w + w)

166 = 2(22w)

166 = 44w

166/44 = w

w = 3.773

From Eq. 3

g = 21(3.773)

g = 79.227

Check:

From Eq. 2:

166 = 2(79.227 + 3.773) = 2 * 83

The vertex angle of the isosceles triangle is 22°.

What is isosceles triangle?

A triangle with two equal sides is said to be isosceles. Also equal are the two angles that face the two equal sides. In other terms, an isosceles triangle is a triangle with two sides that are the same length.

We know that an isosceles triangle is composed of a vertex angle and two base angles. The base angles are congruent to each other. We also know that the sum of a triangle's angles is 180degrees.

Base angle = 3vertex angle+13.

=> 2base angle + vertex angle = 180°

=> 2(3 vertex angle +13)+vertex angle = 180°

=> 6 vertex angle+26+vertex angle = 180

=> 7 vertex angle = 180-26
