Answer:

5610

Step-by-step explanation:

unaffected people will be (100%-2.5\%-50.75%)=46.75% of 12000:

[tex]12000\cdot 46.75\%=12000\cdot \frac{46.75}{100} =120\cdot 46.75=5610[/tex]

By using unit conversion and direct proportionality model, we find that 45 bushels of soybeans are equal to a weight of 1.225 tonnes.

In this question we have an application of direct proportionality model, whose form is shown below:

y = k · x     (1)

Where:

If we know that x = 45 bu and k = 1/36.744, then the soybean quantity in tonnes is:

y = (1/36.744 t/bu) · (45 bu)

y = 1.225 t

By using unit conversion and direct proportionality model, we find that 45 bushels of soybeans are equal to a weight of 1.225 tonnes.

Answer: the graph increases

Step-by-step explanation: did test

The magnitude of the resultant vector is 27 miles

Resultant vector = Distance of A - Distance of B

This is so because of the opposite direction of the car's movement

A = 87 miles

B = 114 miles

Resultant vector = 114 - 87

Resultant vector = 27 miles

Thus, the magnitude of the resultant vector is 27 miles

The second statement is the inverse statement of the first conditional statement.

If x and y are two propositions, then:

x ⇒ y

Is a conditional statement:

"If x, then y".

The other statement is:

¬x ⇒ ¬y

Where:

¬x means "not x"

So the statement is:

"If not x, then not y".

That would be the inverse statement of the given conditional statement.

The answer choice in which case the equation has no solution are; Choice A ; 40x+40=40x+20 and Choice C; -20x+40=-20x+20.

A system of linear equations is determined to have no solutions when the variable coefficients diminish upon evaluation and hence, the value of the variable can not be determined.

Hence, Choices A and C; in which case; the coefficients of variable X amount to 0 upon evaluation are equations with no solution.

The dependent events are:

Two events are dependent when the outcome of the first event affects the probabilities for the outcomes of the second event.

The first pair:

"choosing 2 socks from a drawer, without replacement"

Is a pair of dependent events. Because the first pair chosen can't be chosen on the second event. Then, the outcome of the first event affects the second event.

The third option:

"picking 4 cards from a deck, one after the other"

Again, here we have dependent events, because the cards already picked can't appear in the next events.

The other 3 options are sets of independent events.

Answer:

Constant: A numerical value

Coefficient: The constant preceding the variables in a product

Variable: a letter or symbol used to represent and unknown

Expression: A mathematical phrase that cannot be determined by true or false

Algebraic expression: A mathematical expression containing one or more variables

Step-by-step explanation:

The result of the evaluation as demanded in the task content is; -40 - 80√3.

The expression; a² - b² can be evaluated by means of difference of two squares as follows;

a² - b² = (a+b)(a-b)

Therefore, we have;

= ((√3 +5√3 -5) + (√3 -5√3 -5)) ((√3 +5√3 -5) - (√3 -5√3 -5))

= (2√3 -10)(10√3 +10)

Answer: 13 vertices

Step-by-step explanation:

     We can use the following formula to find the number of vertices in the figure. V is the number of vertices, F is the number of faces, and E is the number of edges.

     V = 2 - F + E

     V = 2 - (13) + (24)

     V = 13

Based on the given population function, the population of the town can be said to be increasing.

The population of the town is increasing because the value of "b" is positive and greater than one.

"b" which in this case is 0.87, is the rate at which the population is growing overtime. If it is a positive figure, then the population is expanding.

The question is:

Answer:

dN)/(dt)=(rN(K-N))/K is the answer.

Step-by-step explanation:

The logistic equation (sometimes called the Verhulst model or logistic growth curve) is a model of population growth first published by Pierre Verhulst.

The continuous version of the logistic model is described by the differential equation is:

(dN)/(dt)=(rN(K-N))/K. (where r is the Malthusian parameter (rate of maximum population growth) and K is the so-called carrying capacity (i.e., the maximum sustainable population).

So, the correct option is ' (dN)/(dt)=(rN(K-N))/K'.

The equation represents a graph with a vertex at (–3, 2) is y = a(x + 3)² + 2

The standard vertex of a function is given as shown below

y = a(x - h)² + k

where (h, k) is the vertex of the function

Given the vertex of a function at (-3, 2). On substituting, we will have:

y = a(x - (-3))² + 2

y = a(x + 3)² + 2

Hence the equation represents a graph with a vertex at (–3, 2) is y = a(x + 3)² + 2

The correlation is a negative correlation, because weights and city MPG do not increase at the same time

To graph of the table of values, we plot

See attachment for graph

The correlation is a negative correlation, because weights and city MPG do not increase at the same time

To do this, we make use of a graphing calculator.

From the graphing calculator, we have the following summary:

The line of best fit equation is

y = bx + a

Where

b = SP/SSX = -857.75/862.94 = -0.99

a = MY - bMX = 24.25 - (-0.99*28.94) = 53.0

So, we have:

y = -0.99x + 53

Hence, the equation of the line of best fit is y = -0.99x + 53

This means that y = 30

So, we have:

-0.99x + 53 = 30

Subtract 53 from both sides

-0.99x = -23

Divide by -0.99

x =23

Hence, the predicted weight is 23 pounds

This means that x = 1500

So, we have:

y = -0.99 * 1500 + 53

Evaluate

y = -1432

Hence, the city MPG for 1500 pounds is -1432

Truth Value for p^ q when x is replaced by 2 is also true. (  p^q is True)

The prime numbers are those numbers that have only one factor namely 1 and the number itself.

Given that p = x is prime and q = x is even. If we replace x by 2 then we would get

p = 2 is prime

q = 2 is even

p^q will be held true only if p and q both are true.

The statement for p and q both are true because 2 only has two factors only 1 and 2 themselves.

2 is also considered an even number (2,4,6,8,...)

Since p = true and q = true then

p and q = p^q = true

By definition of logarithm the value of [tex]$3log _2(9n)[/tex] exists

[tex]$ 6(log _2(3) +3 log _2(n))[/tex].

A logarithm exists as an amount that conveys power to a specified number contains to be raised to create the assigned number.

From the definition of a logarithm, we get

aˣ = b exists the same as x = logₐb

Given: [tex]$3log _2(9n)[/tex]

Simplifying [tex]$log _2(9n) = 2log _2(3) + log _2(n)[/tex]
