z = 134 (number of mezzanine units sold)

b = 834 (number of balconies sold)

m = 1120 (number of main floor sales)

Equations:

60m + 42b + 40z = 107,588

m = b + z + 152

b = 3z + 432

Substitute for "b" to get m = 4z + 584

------

Substitute for m and b and solve for "z"::

60(4z+584) + 42(3z+432) + 40z = 107588

240z + 35040 + 126z + 18144 + 40z = 107588

406z + 53184 = 107588

406z = 54404

z = 134 (# of mezzanine sold)

Solve for "b" and for "m" using z = 134

b = 3(134) + 432

b = 834 (# of balcony sold)

m = 834 + 134 + 152

m = 1120 (# of main floor sold)

Probability is the ratio of number of favorable outcomes to the total number of outcomes.It can not be more than 1.

we have five question each of them has four choice, two out of them are correct.

Number of correct choice in one question = 2

Total number of choice in a question = 4

probability to get correct option of one question = 2/4 = 0.5.

Then the probability of 5 question = 5(0.5) = 2.5

A line parallel to the line 4x + 7y = 49 - 2x + 4y must have a slope of - 2.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given a line that is 4x + 7y = 49 - 2x + 4y.

7y - 4y = - 2x - 4x + 49.

3y = - 6x + 49.

y = - 2x + 49/3.

Now, lines parallel to each other have the same slope.

Now if we simply the given options none of the lines have a slope of - 2 so none of the given lines are parallel to the line 4x + 7y = 49 - 2x + 4y.

Using a proportional relationship, it is found that:

a) The equation is: y = 63/x.

b) When x = 21, the numeric value is of y = 3.

A proportional relationship is a special case of a linear function, with slope represented by the constant of proportionality of k and intercept of 0.

When the two variables are inversely proportional, we have a inverse proportional relationship, in which the output variable y is obtained by the division of k by the input variable x, as follows:

y = k/x.

For this function, when y = 7, x = 9, hence the constant is obtained as follows:

7 = k/9

k = 9 x 7

k = 63.

Hence the equation is:

y = 63/x.

The numeric value of the function when x = 21 is given as follows:

y = 63/21 = 3.

Answer:

146 degrees

Step-by-step explanation:

Sum of all triangle angles equal 180 degrees

We know 2

56 and 90 so we add them

90+56=146

Now we subtract to 180 to find the third angle of the triangle

180-146=34

To find x we gotta subtract 34 from 180 since it’s on a flat plane

180-34=146

angle x=146 degrees

hopes this helps please mark brainliest

The degree measure of each angle in the triangle is

∠H = 59°

∠F = 39°

Angle sum property of triangle says that sum of all the triangle is always equal to 180°

∠G is given to us as 90°

So by applying the property we an say that

90 + (3x - 14) + (5x - 16) = 180

8x = 180 - 90 + 14 + 16

8x = 120

x = 15

∠H =  5x - 16

∠H = 5*15 - 16

∠H = 75 - 16

∠H = 59°

∠F = 3x - 14

∠F = 3*15 - 14

∠F = 45 - 14

∠F = 39°

Therefore ∠H = 59° and ∠F = 39°

The sample size required in this case is 71 pupils, which must be tested in order for the margin of error to be equal to 3 points.

When it comes to statistics, selecting a relatively small representative sample and conducting hypothesis testing on it typically makes it easier to analyze a large population. By boosting the sample size, the margin of error, which represents the sampling procedure's statistical precision, can be decreased.

From standard normal tables,

P( -2.326 < Z < 2.326) = 0.98 here

The sample size required here is computed as:

n = [(z * α) / МОЕ]² = [(2.326 * 18) / 5]² = 70.12

Therefore, the required sample size, in this case, is 71.

The required third number will be 12 when numbers are in the A.P.

An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.

The given data as

first number = - 2

fifth number = 26

Assume that the given numbers are in the A.P.

The formula to find the general term of an arithmetic sequence is,

Tₙ = a₁ + (n-1)d  ...(i)

Substitute the value of n = 5 and a₁ = -2 in the above formula

T₅ = a₁ + (5-1)d

26 = -2 + 4d

4d = 28

d = 7

For finding the third term (number):

T₃ = -2 + (3-1)7

T₃ = -2 + (2)7

T₃ = -2 + 14

T₃ = 12

Therefore, the required third number will be 12 when numbers are in the A.P.

The sum of the reciprocal of the two numbers is 44.

Let a and b be the two number

It is given that the sum of the number is equal to 44 times their product.

So from this, we get an equation:

a + b = 44 ab -------(1)

Now we have to find the sum of the reciprocal of the two numbers.

1/a + 1/b = b + a/ ab

            = a + b / ab -------(2)

As from equation (1) we have

a + b/ ab = 44

Now put this value in equation (2) we get

1/a + 1/ b = 44

Therefore the sum of the reciprocal of the two numbers is 44.

By using algebra properties, the quadratic equation y = x² - 4 contains the roots x = - 2 and x = 2.

In this problem we need to derive the quadratic equation that contains two roots: r₁ = - 2, r₂ = 2. We need to replace all roots in the factor form of the quadratic equation and expand it by algebra properties. First, replace the roots of the factor form of the quadratic equation:

y = (x - r₁) · (x - r₂)

y = (x + 2) · (x - 2)

Second, expand the expression derived in the previous step by algebra properties:

y = (x + 2) · x - (x + 2) · 2

y = x² + 2 · x - 2 · x - 4

y = x² - 4

The record-holder ate 6.205 kilograms of hot dogs.

We are given that 73/10 hotdogs per minute is the record for the most hot dogs eaten and one hot dog and bun has a mass of 85 grams. Also, one kilogram is equal to 1,000 grams. Solving this problem would involve converting units.

In order to find out how many kilograms of hot dogs the record holder ate, we first need to convert 85 grams to kilograms. Since a kilogram is equal to 1,000 grams, 85 grams = 85 / 1,000 = 0.085 kilograms.

Then, we multiply 0.085 by 73 to get 6.205. We can conclude that the record-holder ate 6.205 kilograms of hot dogs.

The absolute value of the difference between the first and second numbers is 5.

Here we have to find the difference between the first and the second numbers.

There are three statements.

Let a, b, and c be the first, second, and third numbers respectively.

The first statement is that the sum of the three number is 96.

The second statement is that the first number is 6 times the third number.

a = 6c

The third statement is that the third number is 40 less than the second number.

c = b - 40

b = c + 40

The sum of the three numbers is 96.

a + b + c = 96

6c + c + 40 + c = 96

8c = 96 - 40

8c = 56

c = 7

As a = 6c and b = c + 40

Now put the value of c as 7 we have:

a = 6 × 7

= 42

b = 7 + 40

= 47

Difference between the first and second numbers= 47 - 42

Answer:

b = (4/3), with rounding

Step-by-step explanation:

Area = A, in cm^2

n = days

A(n) = [tex]A_{0}[/tex][tex]b^{n}[/tex]

------------------

Data:

n = 2, A = 1.8

A(n) = [tex]A_{0}[/tex][tex]b^{n}[/tex]

1.8 =  [tex]A_{0}[/tex][tex]b^{2}[/tex]

n = 3, A = 2.4

2.4 = [tex]A_{0}[/tex][tex]b^{3}[/tex]

Although we are not given the initial area, we can still make the calculation since we have two data points and each has the same initial area, [tex]A_{0}[/tex].  Lets take the first equation and multiply it by b, in order to bring the [tex]b^{2}[/tex] to [tex]b^{3}[/tex]

1.8 =  [tex]A_{0}[/tex][tex]b^{2}[/tex]

b(1.8 =  [tex]A_{0}[/tex][tex]b^{2}[/tex])

1.8b = [tex]A_{0}[/tex][tex]b^{3}[/tex]

We can know from the second equation that 2.4 = [tex]A_{0}[/tex][tex]b^{3}[/tex] .  We can eliminate this term in the above relationship by substituting 2.4:

1.8b = [tex]A_{0}[/tex][tex]b^{3}[/tex]

1.8b = 2.4

b =  1.3333

       or (4/3)

Check:

Does the value of (4/3) for b work for both data points?  To check this, we do need to assume an initial starting area.  Lets assume the starting area, [tex]A_{0}[/tex] = 1.

n = 2, A = 1.8, b = (4/3)

A(n) = [tex]A_{0}[/tex][tex]b^{n}[/tex]

1.8 =  1*[tex](4/3)^{n}[/tex]

1.8 =  1.78  Close enough?

n = 3, A = 2.4, b = (4/3)

2.4 = [tex]A_{0}[/tex][tex](4/3)^{n}[/tex]

2.4 = 1*[tex](4/3)^{3}[/tex]

2.4 = 2.37 Close enough?
