Which statements about experimental probability are true?

Answer:

46

Step-by-step explanation:

irdk

140 feet travel in 20 rotations.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas. 12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas. This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

The wheel moves 56 ft in 8 rotations.

Now, in 1 minute the wheel travel

= 56/8

= 7

Now, in 20 rotation the wheel travels

=20 x 7

= 140 feet

Hence, 140 feet travel in 20 rotations.

Answer:

  Desiderio

Step-by-step explanation:

The number of sides of a regular polygon is multiplied by the length of the side to get the perimeter. To find the number of sides, the perimeter must be divided by the number of sides.

Brianna's description requires that division look like ...

  31.5/6.3 = 5

Desiderio's description requires that division look like ...

  5n/n = 5

Since we're supposed to tell the number of sides without doing any calculation, it seems Desiderio's description is better. (We have to realize that n/n = 1, so the factors of n cancel.)

Some of us are familiar with multiplication tables and quickly realize 30/6 = 5 based on memory. Which realization is faster depends on your memory and experience. Most would say evaluating Brianna's description cannot be done without calculation.

Answer: B

Explanation: B has-235 which is in the above list of y

Answer:

C

Step-by-step explanation:

Hello Jasmine. So let's try out all of the functions starting from the first one.

For A, assuming value of x = 3. (176*3)-59 = 469, so it is incorrect.

For B, assuming value of x =3. (-59*3)-235= -412, so it is incorrect.

For C, assuming value of x=3. (-59*3)-176= -353 (which is the corresponding value of y in the table.)

Which means the correct answer is C, if you need further help please let me know.

Part a) Use a system of inequalities to model the scenario

Let

x-------> represent babysitting hours

y-------> represent tutoring hours  

we know that

Part b) Use the model created in part A to create a graph representing Jeanne’s probable income earned and possible number of hours worked this week

we know that

--------> inequality  

This inequality represent Jeanne’s possible number of hours worked this week

Using a graph tool

the solution of this inequality is the shaded area

see the attached figure N  

--------> inequality    

This inequality represent Jeanne’s probable income earned this week

Using a graph tool

the solution of this inequality is the shaded area

see the attached figure N  

Part c) Analyze the set of coordinate values that represent solutions for the model created in part A. Choose one of the coordinates within the solution and algebraically prove that the coordinate represents a true solution for the model

If the point is a solution, it must satisfy both inequalities.

Prove algebraically

substitute the value of x and y in the inequalities

inequality

inequality  

-------> is ok

the point A satisfy both inequalities

therefore

the point A is a solution of the system

Step-by-step explanation:

The amount of time that is taken for the population to reach 1,000,000 will be 17.27.

The exponent denotes that the base will rise to a specific level of strength. The base is X, and the power is n.

The growth of a bacteria population is modeled by the equation given below.

[tex]\rm p(h) = 1,000 \times e^{(0.4h)}[/tex]

Then we have

Then the amount of time which is taken for the population to reach 1,000,000 will be

[tex]\rm 1,000,000 = 1,000 \times e^{(0.4h)}\\\\1000 = e^{0.4h}[/tex]

Taking log on both sides, then we have

ln 1000 = 0.4 x h x ln e

    6.91 = 0.4 x h

         h = 17.27

Answer:

Ms. Felix would spend $491.75 on her order.

Step-by-step explanation:

First, let's identify the components of this word problem that we'll need to solve it. We know that Staples charges $28 for 8 boxes of pencils, and $47 for 4 pencil sharpeners. Before we do anything else, we'll find the unit price of  the pencils and pencil sharpeners to make it easier for us. Let's begin with the boxes of pencils. 28 ÷ 8 = $3.50 per box of pencils. As for the pencil sharpeners, 47 ÷ 4 = $11.75 per sharpener. Now that we know the basic costs, let's use them to solve our problem at hand. We'll multiply the number of items ordered by the base cost of the item.

Boxes Of Pencils:

70 × $3.50= $245.00

Sharpeners:

21 × $11.75= $246.75

Now that we know the cost of the two seperate items Ms. Felix ordered, let's add them to get our final answer.

Our final answer would be $491.75.

Answer:

factorise it

Step-by-step explanation:

in the method  ax2 + bx + c

so it can be done just in y

find a common factor

well there isn't one but we can see that we need to factorise it

+1 y2  times  6= 6

because there is only 1 y and you times it by 6

you'll see why when we factorise this

so x the squared number (1) x 6 =6

and the middle number is 5

find two numbers that

x multiply to make six

and add+  to make -5

those numbers are

-3

-2

because -2 + -3 = -5        and -2 x -3 = positive 6

so our answer of y2 + 5y + 6

 is identical to = y2 -3y -2y +6

factorise in half

y2 -3y                   -2y +6

so now we can factorise!

in this bracket we have

a common factor of y                                  in this bracket we have common                                                

                                                                        factor of 2

= y (y -3)                             +                         =    -2(y-3)

BUT THERE IS STILL ONE MORE

THEN WE CAN SEE A COMMON FACTOR OF Y-3

put the  (y-3)  in front and the  (-y-2) is left

put y from first bracket and -2 from second bracket into a seperate bracket

yay! factorised

BUT THERE IS STILL ONE MORE

ANSWER =  (Y-2) (Y-3)

you can use the rainbow multiplying out of bracket method to prove it works.

PLZ GIVE BRAINLIEST

how it would be written out:

y2 + 5y + 6

y2 -3y -2y +6

y2 -3y       -2y +6

y (y -3)       -2(y-3)

(Y-2) (Y-3)

Move all the variables to the left, using the opposite operation:

Answer:

Step-by-step explanation:

Circumference / 2 times the radius (diameter) = pi

Circumference / pi = diameter (diameter / 2 = radius)

Answer:

for the first equation you will place a point at (0, 3)

you will then go "up 1 and over 1" and place another point (this is your slope) continue doing this until you have formed a line. you may also go "left 1 down 1" to go the opposite direction, creating a negative slope & straight line.

for the second equation you will place a point at (0, -3)

you will then go "up 1 and over 2" and place another point. repeat this a few times. then you will go to (0, -3) and go "left 1 down 2" and create the negative slope effect. this will give you a straight line.
