Step-by-step explanation:

The probability of selecting a receipt of more than $25 is 0.33.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

For the given situation,

The amount on receipts in $, S= { 15,25,17,23,37,28 }

⇒ [tex]n(s) = 6[/tex]

The amounts are grouped as more than $25 and less than $25.

The event is the amount on receipt more than $25, [tex]e = (28,37)[/tex]

⇒ [tex]n(e)=2[/tex]

The formula to find the probability of an event,

[tex]P(e)=\frac{n(e)}{n(s)}[/tex]

⇒ [tex]P(e)= \frac{2}{6}[/tex]

⇒ [tex]P(e)=\frac{1}{3}[/tex]

⇒ [tex]P(e)=0.33[/tex]

Hence we can conclude that the probability of selecting the receipt of more than $25 is 0.33.

Answer:

the function is odd

Step-by-step explanation:

functions that are symmetric with respect to the y axis are even functions

functions that are symmetric with respect to the origin (the 0,0 point) are odd functions (which means that if you flipped it 180 degrees it will still look the same)

have a nice day!

Answer:

(3x)¹²

Step-by-step explanation:

(3x³)⁴ is in form of (e³)⁴ which can be written as e³×⁴

= e¹²

so (3x³)⁴ can be written as (3x)¹²

Answer:

3x¹²

Step-by-step explanation:

According to the power rule of exponents, to simplify a power of a power, you multiply the exponents and keep the base the same. In this case, 3 and 4 are the exponents. 3 times 4 is 12. So the answer would be 3x to the power of 12.

Answer:

(x + 1)(x - 7) is the odd one.

Step-by-step explanation:

1) sum= 8

Product = 7

Factors = 1 , 7    {1*7 = 7  & 1+7 = 8}

x² + 8x + 7 = x² + x + 7x + 7

                 = x(x +  1) + 7(x + 1)

                 =(x +1 )(x + 7)

2) x² - 8x + 7 = x² -x -7x + (-1)*(-7)

                      = x(x - 1) - 7(x - 1)

                     =(x - 1)( x - 7)

3)Sum = 6

Product = -7

Factors = (-1) , 7   { -1 + 7 = 6   & (-1)*7 = -7}

x² + 6x - 7 = x² - x + 7x - 7

                   = x(x - 1) + 7(x - 1)

                   = (x  - 1)(x + 7)

Answer:

Step-by-step explanation:

1) Determining the nature of roots:

Quadratic equation: ax² + bx +c = 0

Find D (Discriminant) using the  D = b² - 4ac

If D = 0 , then the two roots are equal.

If D > 0, then the equation has two distinct real roots.

If D < 0, then the roots are complex/ imaginary.

One can find the sum and product of the roots using the below mentioned formula.

1) sum of roots = [tex]\frac{-b}{a}[/tex]

2) Product of roots = [tex]\frac{c}{a}[/tex]

If sum and product of the roots are given, one can frame the quadratic equation by   x² - (sum of roots)*x + product of roots = 0

2) i) x² - 6x + 9 = 0

a = 1 ; b = -6  and c = 9

D = (-6)² - 4 * 1 * 9 = 36 - 36 = 0

D = 0. So, two equal roots

ii) x² - 4x + 3 = 0

a = 1 ; b = -4 ; c = 3

D = (-4)² - 4 * 1 * 3 = 16 - 12 = 4

D > 0. So, two distinct real roots.

iii) x² - 4x - 3 = 0

a = 1 ; b = -4 ; c = -3

D = (-4)² - 4*1*(-3) = 16 + 12 = 28 > 0

D > 0. So, two distinct real roots.

iv) x² - 4x + 7 = 0

a = 1 ; b = -4 ; c = 7

D =(-4)² - 4 *1 *7 = 16 - 28 = - 12

D< 0. So, two imaginary/ complex roots.

Answer:

Step-by-step explanation:

Answer:

34

Step-by-step explanation:

We actually don't care what amount of paper is white, we just need the amount per truck. If there were 2 trucks, they would each take half of the total amount of paper. If there were 3 trucks, they would each take a third of the total amount of paper. And so on for 4,5,6,etc.

For 28 trucks, they would each take a twenty-eighth of the total amount of paper. So, the amount each truck takes is just [tex]952/28=34[/tex].

So, the answer is [tex]\boxed{34}[/tex] and we're done!
