Applying the midpoint formula, the coordinates of B are: (-7, 4).

The midpoint formula is:

M(x, y) = [(x2 + x1)/2, (y2 + y1)/2]

Given:

M(x, y) = (-3, 0)

A(x1, y1) = (1, -4)

B(x2, y2) = (?, ?)

Plug in the values into the midpoint formula:

M(-3, 0) = [(x2 + 1)/2, (y2 + (-4))/2]

Isolate each coordinate

-3 = (x2 + 1)/2

-6 = x2 + 1

-6 - 1 = x2

x2 = -7

0 = (y2 - 4)/2

0 = y2 - 4

y2 = 4

Therefore, applying the midpoint formula, the coordinates of B are: (-7, 4).

Answer:

(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

The expression to find the population of fruit flies Lavania observed after 6 days is 9 + 5 * 20 and the value is 109

The given parameters are

Day 1 = 20 fruit flies

Day 6 = 9 more than 5 times as many fruit flies on day 1

The above expression can be rewritten as

Day 6 = 9 + 5 * Day 1

This gives

Day 6 = 9 + 5 * 20

Evaluate the product

Day 6 = 9 + 100

Evaluate the sum

Day 6 = 109

Answer:

27.25 feet long

Explanation and Check part below

Hope this helps :)

Step-by-step explanation:

The area is 599.5 square feet and it is 22 feet wide. So in order to find the area we have to multiply the width (22 feet wide) and the legth (unknow number which will stand for "x"). Since we area multiplying the width and legth we need to do the inverse operation which is dividing. We didvide the area 599.5 by the width 22 to get 27.25 feet long.

22x = 599.5

----- -------- <------ Fraction bar/divide

22 22

x = 27.25

Check:

When a number is next to parenthesis it means to multiply the 2 numbers.

22 (27.25) = 599.5

599.5 = 599.5

Answer:

x=7, y=11

Step-by-step explanation:

Using simultaneous equations we can sub y in equation 1 into equation 2.

Equation 1. y=2x-3

Equation 2. x+y=18

Since y=2x-3 we can replace it so that

2'. x+2x-3=18

Now simplify

= 3x-3=18

Add 3 onto both sides to undo the subtraction of 3 so that,

3x=21

Now divide both sides by three to undo the multiplication of 3 so that,

x=7

Now sub in x (which is 7) into one of the equations to find y

7+y=18

To undo the five, subtract 7 from both sides so that

y=11

Answer:

57

Step-by-step explanation:

2 out of 3 can be expressed as 2/3. Since we are looking at the 1 out of 3 people, we can use the expression 1/3 x 171 or 171/3, which equals 57

(2) [y = (-10)]

(3) (m=3/4)

(4) (b = 0)

(4)[(-10 b+5)=(7 b+5)]

(5)[(r+15)=(4 r-6)]

(6)[(10-2 v)=(-5 v-50)]

We are required to find the solution of all the equations mentioned above.

Considering equation (1), we get,

{[(4 x+1)=(2 x-5)] }

or,(4 x-2 x)=[(-1)-5]

or, 2 x=-(1+5)

or, 2 x=-6

or, x={-6}/{2}=(-3)

Considering equation (2), we get,

{[(y-3)=(-3 y-43)] }

or, (y+3 y)=(3-43)

or, 4 y=(-40)

or, y=(-10)

Simplifying equation (3), we get,

{[(7-14 m)=(2 m-5)] }

or, (7+5)=(2 m+14 m)

or, 12=16 m

or, m={12}/{16}={3}/{4}

Simplifying equation (4), we get,

{[(-10 b+5)=(7 b+5)] }

or, (5-5)=(7 b+10 b)

or, 17 b=0

or, b=0

Simplifying equation (5), we get,

{[(r+15)=(4 r-6)] }

or, (15+6)=(4 r-r)

or, 3 r=21

or, r=7

Finally, Simplifying equation (6), we get,

{[(10-2 v)=(-5 v-50)] }

or, (5 v-2 v)=[(-10)-50]

The variables that

x + y = 2100  

5 x + 7 y = 11700  

Let x = total dollar amount of sales of phone;

      y = total dollar amount of sales of computer

for total sales of phones anna earns 5% commission

So anna 's commission = 5% of x

                                       = 0.05x

for total sales of computer anna earns 7% commission

So anna 's commission = 7% of y

                                       = 0.07y

Given the total sales; x + y = 2100

And commission; 0.05x + 0.07y = 117; or 5x + 7y = 11700

Therefore the system of equations are

x + y = 2100   …….equation (1)

5 x + 7 y = 11700  ……equation (2)

The total surface area of the pyramid 806.12 [tex]m^{2}[/tex].

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

Side (s) = 12

Altitude (h) = 6

Area = 3√3/2*s² + 3*s*√(h²+3s²/4)

Area = 3√3/2*(12)² + 3*(12)*√[6²+3(12)²/4]

Area = 806.12 [tex]m^{2}[/tex]

A 3D object's surface area is the entire area that all of its faces cover. For instance, the surface area of a cube is its surface area if we need to determine how much paint is needed to paint it.

The required answers are-

Part a: The equation that represents the total cost C is C = 250 + 7x.

Part b: The equation that represents the average cost A per person is A = 250 + 7 = 257.

Part c: The estimate number of people who must attend before the average cost drops to $15 per meal is 25.

Part d: The average cost keeps on decreasing exponentially and then becomes straight.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

Rental of banquet hall = $250

One time charge for meal = $7 per plate

x = the number of people who attend.

Part a: The equation that represents the total cost C

Since there are x people in the banquet

So, number of plates = x

Thus, Total One time charge for meal = 7x

So Total Cost = Rental of banquet hall + Total One time charge for meal

⇒ C = 250 + 7x

this is the equation that represents the total cost C

Part b: The equation that represents the average cost A per person

Putting x = 1 in the above equation of total cost we get,

A = 250 + 7 = 257

this is the equation that represents the average cost A per person

Part c: The estimate number of people who must attend before the average cost drops to $15 per meal

From the graph it is seen that there are 25 people who must attend before the average cost drops to $15 per meal.

Part d: what happens to the average cost as the number of people who attend increases.

The average cost keeps on decreasing exponentially and then becomes straight.

The required answers are-

Part a: The equation that represents the total cost C is C = 250 + 7x.

The value of term a9 is 9k+32.

The difference between any two consecutive integers in an arithmetic progression (AP) sequence of numbers is always the same value.

The formula of Arithmetic progression is

a(n) = a1 + (n - 1)d

given that the term of arithmetic sequence and common difference,

a1 = 4 and d = K+4.

now find the value of term a9.

a(n) = a1 + (n - 1)d

now, substitute a(n) = a9, a1 = k, d = k+4.

a9 = k + (9 - 1)(k+4)

For the area of triangle, the constant of variation is 1/2.

The link between the independent (x) and dependent (y) variables is shown by a constant of variation. A continuous relationship between the variables indicates to the user that there is one; it does not alter regardless of how the scenario changes.

It can be employed to ascertain how the dependent variable will alter in response to changes in the independent variable. For instance, if a person drives continuously at the same pace, they may calculate their distance by multiplying the number of hours they spent driving by the speed they were moving at. In this instance, the speed is the constant since it remained constant regardless of how long or how far they travelled during the journey.

The expected value of chi-square statistics is not significantly different from the observed value.

What is chi-square statistics?

Chi-square statistics is defined as a measure that is used to denote the difference between the expected frequencies and the observed frequencies of an event. It is illustrated using the symbol, 'χ2'.

Deciding for the goodness of a fit

The assigned value of chi-square is 1.273 while the critical value is 13.388

The hypotheses for the goodness of fit test are given below:

Null Hypothesis: the expected value is not significantly different from the observed values

Alternate Hypothesis: the expected value is significantly different from the observed values

We know that the chi-square test is right-tailed.

Further, the value of test statistics is 1.273, which is less than the critical value, 13.388

Thus we fail to reject the null hypothesis and we accept it.

Hence, we can conclude that the expected value is not significantly different from the observed value.
