If you were to randomly survey 500 people each from the two largest US cities, would this be a random sample? Why or why not?​

Answer:

so, with terms like -3x and -8x remember to keep the negative or positive sign the same when combining like terms.

in this instance the simplified expression would be:

15 - 11x

because -3x - 8x = -11x

does this make sense? lmk if u need help

Answer:

Step-by-step explanation:

So the division property states that if both sides of an equation are equal and whenever you divide both sides of that equation by the same number they should stay equal. Example

12=12 right? so if I divide both 12 and 12 by 3 I should get 3=3

We use this to solve for variable such as x

So new example lets take

5x=25

Since both sides are equal I can divide by the same number and should get an equal number right? So lets divide by 5 on both sides. 5x divided by 5 equals x and 25 divided by 5 equals 5 so my new equation is

x equals 5 or x=5.

If I plug my x=5 back into the equation they should be equal so lets see...

5(5)=25

25=25

And it checks out :)

Given:

The polynomial is

[tex]4x+2x^5-6x^3+2[/tex]

To find:

The standard form of the polynomial and leading coefficient.

Solution:

In standard form of a polynomial, we arrange the terms in descending order of their degrees.

Leading coefficient is the constant value before the variable with highest power.

Let the given polynomial be p(x).

[tex]p(x)=4x+2x^5-6x^3+2[/tex]

The standard form of the polynomial is

[tex]p(x)=2x^5-6x^3+4x+2[/tex]

The highest power of x is 5 and 2 is before [tex]x^5[/tex]. The leading coefficient is 2.

Therefore, the standard form of the polynomial is [tex]2x^5-6x^3+4x+2[/tex] and the leading coefficient is 2.

Answer:

are you sure its a polynomial

Step-by-step explanation:

A polynomial is a combination of terms separated by

+

or

−

signs. A polynomial does not contain variables raised to negative or fractional exponents, variables in the denominator or under a radical, or any special features such as trigonometric functions, or logarithms.

Answer:

32.38°

Step-by-step explanation:

In AXYZ, X = 7.7 inches, y = 4.2 inches and z=7.3 inches. Find the measure of Y to

the nearest degree.

We solve using Cosine rule

Y = arc cos( x² + z² - y²/2xz)

x = 7.7 inches

z = 7.3 inches

y = 4.2 inches

Y = arc cos( 7.7² + 7.3² - 4.2²/2 × 7.7 × 7.3)

Y = 32.38°

Answer:

(1) False

(2) False

(3). False

(4) False

Step-by-step explanation:

According to the problem, calculation of the given data are as follows,

(1). Given,  149 + 769 = 819

By calculating 149 + 769 = 918  

Hence, False

(2). Given,  556 + 336 = 826

By calculating 556 + 336 = 892  

Hence, False

(3). Given,  458 - 248 = 238

By calculating 458 - 248 = 210  

Hence, False

(4). Given,  658 - 228 = 438

By calculating 658 - 228 = 430  

Hence, False

Answer:

c.130

Step-by-step explanation: so first you would plus 20 and 10 and that equals 30 then you would multiply 3 times 30 and that equaled 90 now you have 90+40 which equals 130.

Given:

Point S is translated 5 units to the left and 12 units up to create point S'.

To find:

The distance between the points S and S'.

Solution:

Point S is translated 5 units to the left and 12 units up to create point S'.

The diagram for the given problem is shown below.

From the below figure it is clear that the distance between the point S and S' is the height of a right triangle whose legs are 5 units and 12 units.

By Pythagoras theorem,

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

[tex]SS'^2=(12)^2+(5)^2[/tex]

[tex]SS'^2=144+25[/tex]

[tex]SS'^2=169[/tex]

Taking square root on both sides.

[tex]SS'=\sqrt{169}[/tex]

[tex]SS'=13[/tex]

Therefore, the distance between S and S' is 13 units.

Answer:

the scatter plots shows a positive association.

The statement that  are true for the scatterplot is that the scatterplot shows a positive association.

There are often seen some patterns or some measures of relationships found in  a scatterplots.

Note that if the y variable do increase just when  x variable is increasing, then you can say there is a positive correlation that exist between the variables.

But when the y variable is said to reduce or decrease just as the x variable is increasing, then you can say there is a negative correlation that exist between the given variables.

Step-by-step explanation:

The value of x° is 22° and exterior angle is 25.

Step-by-step explanation:

l can prove like this,

Here,2x°+(103-x)°=(6x-7)°...Being exterior angle

or,2x°+103°-x°=6x°-7°

or,x°+103°=6x°-7°

or,103°+7°=6x°-7°

or,5x°=110°

or,x°=110°÷5=22°

Now,

x°=22°
