Definition of mean, median, mode & range?

Answers

Answer 1

Answer: Mean: Add all the numbers divide by the amount of values
Median: the middle number in a set of data
Mode: the most common number that appears in a set of data
Range: biggest number take away the smallest number

Answer 2

Answer: Mode: number that appears the most
Mean: all the numbers added together and then that number divided by the amount of numbers u counted to get the solution for the addition.
Range: subtract the highest number from the smallest number
Median: put the numbers from least value to the top value and the Median will be in the middle

How would you put this expression in factored form? 4x2 + 11x + 6

Answers

we have

$4x^(2) +11x+6$

Equate the expression to zero

$4x^(2) +11x+6=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$4x^(2) +11x=-6$

Factor the leading coefficient

$4(x^(2) +(11x/4))=-6$

Complete the square. Remember to balance the equation by adding the same constants to each side

$4(x^(2) +(11x/4)+(121/64))=-6+(121/16)$

$4(x^(2) +(11x/4)+(121/64))=(25/16)$

$(x^(2) +(11x/4)+(121/64))=(25/64)$

Rewrite as perfect squares

$(x+(11/8))^(2)=(25/64)$

Square root both sides

$x+(11/8)=(+/-)\sqrt{(25)/(64)}$

$x=(-11/8)(+/-)(5)/(8)$

$x=(-11/8)+(5)/(8)=-(6)/(8)=-(3)/(4)$

$x=(-11/8)-(5)/(8)=-(16)/(8)=-2$

therefore

$4x^(2) +11x+6=4(x+(3)/(4))(x+2)=(4x+3)((x+2)$

the answer is

$(4x+3)((x+2)$

3y+2/4=7 I don't understand this at all

Answers

Don't let the fraction confuse you.

3y + 2/4 = 7

You could multiply each side by 4 to get rid of the fraction:

12y + 2 = 28

Subtract 2 from each side:

12y = 26

Divide each side by 12 :

y = 26/12 or 13/6 or 2 and 1/6

Actually u want to find the value of 'y' step1:rearranging 3y=7-2/4 step2:take LCM and subract 3y=26/4 step3:simplify 3y=13/2 y=13/6

D. $278.29

Answers

Answer:

Step-by-step explanation:

13per mile×1080 mile =140.79

Answer:

Step-by-step explanation:

if you at $24.74 * 6 = 148.5

then you take 1083 * .13 = 140.79

then add the two number to get 289.29
