Answer: 50,562 people

Step-by-step explanation:

The city population in the beginning of 1953 was 9,903.

Grows at 5.4% each year.

Population in beginning of 1984 can be acquired through compound interest.

Periods = 1984 - 1953 = 31 years

Population in 1984 = 9,903 * (1 + 5.4%)³¹

= 9,903 * 5.1057428421476776548111

= 50,562 people

Answer:

The graph I have attached an image of does not represent a function.

Step-by-step explanation:

This is because if we take the vertical line test, which is to draw a vertical line through any point of the x-axis. If the line passes through two points when it is vertical, the line doesn't represnt

a function.

Graph fourth is not representing a function because it failed the vertical line test option (D) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

Four graphs is shown in the picture.

As we know we can identify whether the graph is representing a function or not by using a vertical line test.

This is due to the vertical line test, which involves drawing a vertical line through any x-axis point. When a line is vertical and runs through two locations, it does not represent a function.

Thus, the graph fourth is not representing a function because it failed the vertical line test option (D) is correct.

Answer:

please tell me if there iscany sing after 4xy

Answer:

xy-x+y+1

Step-by-step explanation:

(1-x^2)(1-y^2)+4xy=1-y^2-x^2+x^2y^2+4xy

here, 4xy=2xy+2xy

then, -(x^2-2xy+y^2)+(x^2y^2+2xy+1)=-(x-y)^2+(xy+1)^2

by a^2-b^2=(a+b)(a-b)

(xy+1+x-y)(xy+1-x+y)

1-2x+y-x^2y+x^2=-y(x^2-1)+(x^2-2x+1)=-y(x+1)(x-1)+(x-1)^2

=(x-1)(x-1-xy-y)=-(x-1)(xy-x+y+1)

thus, common factor is xy-x+y+1

Answer:

1) p=1/2

2) V(p)=25

Step-by-step explanation:

We have the function:

[tex]V(p)=100p(1-p)[/tex]

Which represents the variance of the number of left handed people in a group of 100.

Question 1)

We want to find the value of p that maximizes the variance.

Let's examine our function. We can see that it is a quadratic. Therefore, the value of p that maximizes the variance will simply be the x-coordinate of the vertex of our equation.

Let's expand our function:

[tex]V(p)=100p(1-p)[/tex]

Distribute:

[tex]V(p)=100p-100p^2[/tex]

Let's find the vertex of our equation. We can use the following formulas (I switched out the x for p):

[tex]p=-b/2a,\ V(-b/2a)[/tex]

Let's determine our coefficients. The "a" is the coefficient in front of the squared term and "b" is the coefficient in front of the x term.

So, a is -100, and b is 100.

Substitute them into our formula:

[tex]p=-(100)/2(-100)[/tex]

Multiply:

[tex]p=100/200[/tex]

Divide:

[tex]p=1/2[/tex]

So, the x-coordinate (or rather p in this case) of our vertex is 1/2.

To find the y-value, let's substitute it back into our function. We have:

[tex]V(p)=100p-100p^2[/tex]

Substitute 1/2 for p:

[tex]V(1/2)=100(1/2)-100(1/2)^2[/tex]

Evaluate:

[tex]V(1/2)=50-25=25[/tex]

Therefore, our vertex is:

[tex](1/2, 25)[/tex]

So, the value of p that maximizes our variance is p=1/2.

Question 2)

We want to find the maximum variance.

Again, this will simply be the vertex of our quadratic.

This time, it will be the y-coordinate.

We can see that the y-coordinate of the vertex is 25.

So, our maximum variance is V(p)=25.

And we're done!

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

a) p=1/2

b) 25

Answer:

a/b = a * 1/b

Step-by-step explanation:

a/b = a * 1/b

this looks easy....

But what about

a / (1/b) = a*b

if you see any division, you can always multiply BOTH the numerator AND the denominator by the same amount. That is allowed because that is the same as multiiplying by the number 1.

So multiply by b/b and see what happens.

a / (1/b) = b/b * a / (1/b)

group the numerator AND the denominator

a / (1/b) = (b * a ) / b*(1/b)

a / (1/b) = (b * a ) / b/b

a / (1/b) = (b * a ) / 1

a / (1/b) = (b * a )

a / (1/b) = a*b

It is allowed because you can always multiply any number by 1 and that is because that will not change the original number. The number multiplied by 1 remains the same number.

This notion is very powerful and it can be used to turn any division into a multiplycation, and vice versa.

a / (1/b) = a*b

Answer:

This equation generalizes the patterns seen in part D, where a and b represent real numbers:

(a + bi)(a − bi) = a2 + b2.

Answer:

y = 5x-2

Step-by-step explanation:

5x - y = 2

Subtract 5x from each side

5x - y -5x = 2 -5x

-y = -5x+2

Multiply each side by -1

y = 5x-2

Answer:

[tex]y=-2+5x[/tex]

Step-by-step explanation:

[tex]5x-y=2\\\\5x-5x-y=2-5x\\\\-y=2-5x\\\\\frac{-y=2-5x}{-1}\\\\ \boxed{y=-2+5x}[/tex]

Hope this helps.

Extra note: Another correct answer would be [tex]y=5x-2[/tex]

Answer:

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]

From the question the points are

(5,−3) and (5, 8)

The slope is

[tex]m = \frac{8 - - 3}{5 - 5} = \frac{8 + 3}{5 - 5} = \frac{8}{0} \\ [/tex]

Since every number divided by zero is undefined the slope of the line is also undefined.

Hope this helps you

Answer:

Each would equal 10 lbs.

Step-by-step explanation:

60 pounds all together is the weight of 6 boxes, so if you divide 60 by 6, you'll get 10 lbs for each box.

Answer:

each box weighs 10lbs

Step by Step explanation:

if you do 10 20 30 40 50 60 70.... you will see what times what gives you 60 which in this case it is what times 6 gives you 60 so if you list your 6s you will will go until you  get to 6*10 which is 60 but you can do a list of your 10s it is easier that away to be honest. I hope this answer helps you:)

Answer: B

Step-by-step explanation:

The amount of weight barbell acting on a weight lifter os 80 N.

Answer:

I know only one

x=14 being vertically opposite angles

Step-by-step explanation:

algle FGE = GEC

FGE = 180 - (14 + 78)°

= 88°

so angle GEC = 88°

4x + 88 = 180

4x = 180 - 88

4x = 92

x = 92/4

= 23

Answer:

I think it should be 48? but 47 seems to be the closest choice, so i suggest 47

Step-by-step explanation:

let's see what to do...

Figure A is scaled image of Figure B.

So Figure A must be made in a proportion of Figure B.

We should find the ratio:

to find the ratio we have to use the same known sides.

[tex]ratio = \frac{5}{2} \\ [/tex]

Also we have :

[tex]ratio = \frac{12.5}{x} \\ [/tex]

So we have :

[tex] \frac{5}{2} = \frac{12.5}{x} \\ [/tex]

Multiply the sides by 2x :

[tex]5 \: x = 25 \\ x = 5[/tex]

And we're done.

Thanks for watching buddy good luck.
