Step-by-step explanation:

meow meow its 99

Answer 2

Using it's concept, the mean test score is of 4.9.

What is the mean?

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

From the frequency table, the sum of the 30 observations is given by:

0 x 3 + 1 x 2 + 2 x 6 + 3 x 1 + 4 x 1 + 5 x 3 + 6 x 2 + 7 x 4 + 8 x 4 + 9 x 2 + 10 x 2 = 146.

Hence the mean test score is given as follows:

M = 146/30 = 4.9.

The mean test score is of 4.9.

Five more would mean plus five, and in these types of equations you work almost backwards. So if you but +5 in your answer, you need to add the quotient, dividing(/) by 3, and the unknown number is y. so your finial equation would read, y divided by 3 plus 5 is equal to 7 (y/3 + 5 = 7) Hope this was helpful!

Answers

The total equity of the company for  the year ended is $43,900

What is net income?

The net income is the excess of fees earned by Adventure Travel  in the year ended  over its total expenses, in essence, we need to determine its total expenses first and foremost, which comprises of salaries expense, rent expense, depreciation expense, advertising expense and office supplies expense

total expenses=32,800+16,800+3960+4000+2800

total expenses=60,360

fees earned=75,000

net income =fees earned-total expenses

net income=75,000-60,360

net income=$14,640

Now the closing retained earnings comprises of beginning retained earnings plus the net income minus the cash dividends paid

Retained earnings=$14,640+$ 10,260-$1,000

Retained earnings=$23,900

Answers

The object is dropped at a initial height of 99.4 feet. (Correct choice: B)

What is the final velocity of a falling object?

Herein we find the case of a specific object under free fall motion, that is, due to gravity and neglecting effects from air viscosity and Earth's rotation. The kinematic equation is presented below:

v = √(2 · a · h)          (1)

Where:

v - Final velocity, in feet per second.a - Acceleration, in feet per square second.h - Initial height, in feet.

If we know that a = 32.2 ft / s² and v = 80 ft /s, then the initial height of the object is:

80 = √(2 · 32.2 · h)

80 = √(64.4 · h)

80² = 64.4 · h

h = 80² / 64.4

Answers

We have to add 90 pounds of chicken feed that is 40 % to make a chicken feed that is 70 % corn.

How many chicken feed must be added to a given blend?

In this problem we have to prepare a chicken feed with a given concentration by blending two chicken feeds with different concentration. The addition of chicken feed needed can be determined by weighted averages:

(70 / 100) · (270 + x) = (80 / 100) · 270 + (40 / 100) · x

0.7 · (270 + x) = 0.8 · 270 + 0.4 · x

189 + 0.7 · x = 216 + 0.4 · x

Answers

The value of x is -101001 using the base-2 system.

What is a binary number?

A binary number is a number that is expressed in the binary system or base 2 numeral system, according to digital technology and mathematics. It uses the symbols 1 and 0 to represent different numeric values (zero). The positional notation with 2 as a radix is known as the base-2 system.

Given:

1101₂+x₂+11001₂=111₂

To find the value of x.

First, we'll write the binary numbers and multiply each digit of the binary numbers by the corresponding power of two:

1101₂+x₂+11001₂=111₂

(1×2³+1×2²+0×2¹+1×2⁰) + x₂ + (1×2⁴+1×2³+0×2²+0×2¹+1×2⁰) = (1×2²+1×2¹+1×2⁰)

Now, solve the powers.

(8+4+0+1) + x₂ +(16+8+0+1) = (4+2+1)

Simplifying we get,

13+x₂+25=7

x₂=7-48

x₂=-41

1. How much of the original cake has not been shared

2.write a series that represents the amount of the original cake each person has after the fourth division.
3.how much of the original cake will each person have after the fourth division
4. Suppose you continue this process indefinitely. How much of the original cake will each of you receive?

Answers

The cake sharing process of the process using geometric progression gives the following values;

1. The amount of the cake left after the first division is one quarter of the cake

The amount of cake remaining after the fourth division is 1/256 of the original cake

2. The series is; (1/4 + 1/16 + 1/64+ 1/256 + 1/1024) of the original cake

3. 341/1024 of the original cake

4. If the process continues indefinitely each person gets (1/3) of the original cake

What is a geometric progression?

A geometric progression is a sequence of numbers such that a term is found from the previous term by multiplying the previous term by a constant number.

1. Taking the dimensions of the cake as a square, let x represent the side length of the cake, we have;

Amount of cake left after the first division = x/4

The amount of the cake left after the first division is one quarter of the cake

Amount left after the second sharing = x/(4×4) = x/16

Amount left after the third division = x/(4×4) = x/(16×4) = x/64

Amount left after the fourth division = x/(64×4) = x/256

The amount of cake remaining after the fourth division is 1/256 of the original cake

2. After the fourth division, each person receives x/(256×4) = x/1024

The series that represents the amount each person receives after the fourth division is therefore;

(1/4 + 1/16 + 1/64+ 1/256 + 1/1024) of the original cake

3. The amount of the original cake each person gets after the fourth division is therefore;

1/4 + 1/16 + 1/64+ 1/256 + 1/1024 = 341/1024 of the original cake

4. The amount each person receives is given by the sum of a geometric series up to infinity, where;

The first term, a = 1/4

The common ratio, r = 1/4

S = (1/4)/(1 - (1/4)) = (1/4)/(3/4) = (1/4)×(4/3) = 1/3

The amount of the original cake each gets if the process continues indefinitely is (1/3) of the original cake.

The equation for the axis of symmetry of the parabola y = - 4 x² + 24 x - 35 is given by x = 3.

We know that the method to find the axis of the symmetry of the parabola is given by:

x = - b / 2 a

We have the general equation of the parabola as:

y = a x² + b x + c

We have the equation of the parabola as:

y = - 4 x² + 24 x - 35

Comparing from this equation, we get that:

a = - 4

b = 24

c = - 35

Now, substituting the values, we get that:

x = - 24 / 2 (- 4)

x = - 24 / - 8

x = 24 / 8

what line is perpendicular to the line passing through the points (-4, 2) and (4, -1)

Answers

The line that is perpendicular to the line passing through the points (-4, 2) and (4, -1) is y = (8/3)x + 1/2

Equation of a line

From the question, we are to determine the equation of the line that is perpendicular to the line passing through the given points

First, we will determine the equation of the line passing through the given points

The given points are (-4, 2) and (4, -1)

Using the formula,

(y - y₁)/(x - x₁) = (y₂ - y₁)/(x₂ - x₁)

x₁ = -4

y₁ = 2

x₂ = 4

y₂ = -1

Thus,

(y - 2)/(x - -4) = (-1 - 2)/(4 - -4)

(y - 2)/(x + 4) = (-3)/(4 + 4)

(y - 2)/(x + 4) = (-3)/(8)

8(y -2) = -3(x + 4)

8y - 16 = -3x -12

8y = -3x -12 + 16

8y = -3x + 4

y = -(3/8)x + 1/2

Now,

NOTE: A line perpendicular to another has a slope that is the negative reciprocal of the slope of the other line

In the above equation,

The slope of the line is -3/8

∴ The slope of the line that is perpendicular to the line will be 8/3

Thus,

The equation of the line will be y = (8/3)x + 1/2

Hence, the line that is perpendicular to the line passing through the points (-4, 2) and (4, -1) is y = (8/3)x + 1/2
