find the length of segment AB

Using sampling concepts, it is found that the suitable populations are:

a) All Richmond residents.

b) Results of all coin tosses.

c) All pairs of the new type of tennis shoe.

d) The average time on all days is takes to drive from her suburban home to her midtown office.

An example of sampling is asking a sample of 500 Buffalo Bills fans if they think their offense should run the ball more.

Hence, following the example, first identifying the sample and then expanding it for the population the items are answered.

Item a:

Sample of 200 Richmond homes, hence, the population is all Richmond residents.

Item b:

Sample from the results of 100 coin tosses, hence the population is the results of all coin tosses.

Item c:

Sample from 200 pairs of the new tennis shoe, hence the population is all the pairs of this new tennis shoe.

Item d:

Sample for the time it took to drive from her suburban home to her midtown office of 5 days, hence, the population is the time for all days.

Answer:

g(- 1) = -2

Step-by-step explanation:

Given the rational function, [tex]g(x) = - \frac{21 + x}{10}[/tex]:

In order to evaluate and find the value of g(-1), simply substitute the input value into the given function.

[tex]g(x) = - \frac{21 + x}{10}[/tex]

[tex]g(-1) = - \frac{21 - 1}{10}[/tex]

[tex]g(-1) = - \frac{20}{10}[/tex]

g(-1) = -2

Therefore, the output value when g(- 1) is: g(- 1) = -2.

800 girls

Step-by-step explanation:

Ratio is 3:4

let total number of boys be x

3/4=x/1400-x

4x=3(1400-x)

4x=4200-3x

7x=4200

x=600

600 boys

1400-600 = 800 girls

Answer:

Angle 1= 69

Angle 2= 37

Angle 3= 106

Angle 4= 21

Step-by-step explanation:

(Angle 2) The box in the corner is a 90-degree angle. So, 90-53=37

(Angle 1) Now that you have angle 2, add 37+74. You get 111. Subtract 180 and 111.

The answer for angle one is 69.

(Angle 3) Since it is a line, the two angles combined are 180 degrees. 180-74= 106.

(Angle 4) Now that you have angle 3, add 106 and 53. You will get 159. 180-159= 21

Answer:

3321

Step-by-step explanation:

Step-by-step explanation:

complementary = adds up to 90 degrees.

supplementary = adds up to 180 degrees.

the complementary angle of y is 43 degrees.

so, y = 90 - 43 = 47 degrees.

the supplementary angle of y = 47 is

180 - 47 = 133 degrees

Hello!

Given the complementary angle of y is 43º.

90 - 43 => 47°

Find the supplementary angle of y​

180-43 => 137°

Answer:

Step-by-step explanation:

slope formula of a line is as follows:

m = Y2 - Y1/ X2 -X1

and so we'll now plot the given points.

note - the 1st values inside the brackets are that of the x values and the ones that come next are the y values of the given line.

now granted, we'll calculate the change of y and then divide it by the change of x

which is simply -5-(-5)/5-(-2) = 0.

Answer:

C. 9 years

Step-by-step explanation:

For the saw to depreciate completely, the salvage value of the saw would be 0.

Set S(t) = 0 and solve for t

0 = -75t + 675

75t = 675

t = 675/75 = 9 years

The answer to that one is C

Answer:

it cannot be modeled with a rectangle

Step-by-step explanation:

let's eliminate the wrong answers first

1. it cannot be modeled with all positive tiles --- this incorrect because it is all positive, so it CAN be modeled with all positive tiles

2. it can only be modeled with an odd number of tiles -- not true, because 2x^2 is  even number of tiles

3. it can be modeled with a square -- to be modeled as a square, the polynomial have to be factored into square ie (x+2)², but cann't be factored as square, so again not true

therefore, first one is the answer. because you cannot factor the polynomial as such (x+2)(x+3), so it cannot be modeled with a rectangle.

Answer:

A: It cannot be modeled with a rectangle.

Well according to the graph it took Elena 6 weeks to pay her brother back

Step-by-step explanation:

Well the slope is -3, techincially she’s giving back 3 dollars every week, it starts from 18 dollars borrowed.

3 dollars every week until 18 dollars is 6 weeks. Plus the graph shows that the line reaches 0 when it crosses the “6” in weeks

The rate at which she bats is an illustration of ratio and proportions

She's expected to bat 574 times in 162 games

In 131 games, she bat 464 times

Represent this as a ratio

[tex]\mathbf{Ratio = 131 : 464}[/tex]

Let the number of times she bat in 162 games be represented with x.

So, the ratio is represented as:

[tex]\mathbf{Ratio = 162 : x}[/tex]

Equate both ratios

[tex]\mathbf{162 : x = 131 : 464}[/tex]

Express as fractions

[tex]\mathbf{\frac{x}{162 }= \frac{464}{131 }}[/tex]

Multiply both sides by 162

[tex]\mathbf{x= \frac{464}{131 } \times 162}[/tex]

Multiply

[tex]\mathbf{x= \frac{75168}{131 } }[/tex]

Divide

[tex]\mathbf{x= 574}[/tex]

Hence, she's expected to bat 574 times in 162 games

Step-by-step explanation:

First, you need to subtract 16.27 from 80.95 to get how many kilograms of dough he had prepared in that amount of time. 80.95-16.27=64.68. Then you would divide 64.68 by 5.88 to find the total amount of hours he worked. 64.68/5.88=11 hours of work.

The solution for the given system of equations is (4, 6). Therefore, option A is correct answer.

The given system of equations are 6y-4x=20 and -4y+3x=-12.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

Here,

6y-4x=20 ----------(I) and -4y+3x=-12 ----------(II)

Multiply equation (I) by 3, we get

-12x+18y=60 ----------(III)

Multiply equation (II) by 4, we get

12x-16y=-48 ----------(IV)

Add equation (III) and (IV), that is

-12x+18y+(12x-16y)=60-48

⇒ 2y=12

⇒ y=6

So, 6y-4x=20

⇒ 36-4x=20

⇒ -4x=-16

⇒ x=4

The solution for the given system of equations is (4, 6). Therefore, option A is correct answer.
