Answer:

Odds for & against selecting number 7 = 1/14 & 14

Odds for & against selecting number more than 10 = 4/11 & 11/4

Step-by-step explanation:

Odds for event = Prob (event) / Prob (no event)

Odds against event = Prob (no event) / Prob (event)

Prob (No. 7 chosen) = 1/15 , Prob (No. 7 not chosen) = 14/15

Odds for number 7 = (1/15) ÷ (14/15) = 1/14

Odds against number 7 = (14 / 15) ÷ (1/15) = 14

Prob (No. > 10 chosen) = 4 / 15  , Prob (No. > 10 not chosen) = 11/15

Odds for No. > 10 = (4/15) ÷ (11/15) = 4/11

Odds against No. > 10 = (11/15) ÷  (4/15) = 11/4

Answer:13/5  or 2.6

Step-by-step explanation:

Answer:

Step-by-step explanation:

Step one:

given

All Charges

$15 for delivery

and $2.75 per flower

let the number of flowers delivered be x

and the total charges for x flowers be y

the linear function for the total charges is

y=2.75x+15

Step two:

when y=$50

50=2.75x+15

50-15=2.75x

35=2.75x

divide both sides by 2.75

x=35/2.75

x=12.72

Note: we are not given the options. We only solved for the flower arrangements

Therefore the number of flowers in the arrangement Marcus ordered

is 12.72 flowers

Answer:

D. The slope

Step-by-step explanation:

0.15 = 3/20

0.10 = 1/10

Given:

  company A:    y = 3/20x + 25

  company B:    y = 1/10x + 25

y = mx + b

m is slope

b is y-intercept

Answer:

36

Step-by-step explanation:

transpose

x= 4×9

x= 36

Answer:

x = 36

Step-by-step explanation:

If we were to switch around the equation to multiplication, we would have 9 x 4 or 4 x 9 which is 36.

Answer:

we can verify that the determined equation is the same as the equation determines by Misty, hence, we conclude that Misty had correctly determined the equation of the linear function.

Step-by-step explanation:

As Misty determined the equation of linear function:

[tex]y=-2x+9[/tex]

We need to check whether she has got the correct equation or not.

As the linear equation passes through the points  [tex](1, 7)[/tex] and [tex](2, 5)[/tex].

Finding the slope:

The slope between two points  [tex](1, 7)[/tex] and [tex](2, 5)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(1,\:7\right),\:\left(x_2,\:y_2\right)=\left(2,\:5\right)[/tex]

[tex]m=\frac{5-7}{2-1}[/tex]

[tex]m=-2[/tex]

As we know the point-slope form is:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

So, the equation of the line will be:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-5=-2\left(x-2\right)[/tex]

Add 5 to both sides

[tex]y-5+5=-2\left(x-2\right)+5[/tex]

[tex]y=-2x+9[/tex]

From the above calculation, we can verify that the determined equation is the same as the equation determines by Misty, hence, we conclude that Misty had correctly determined the equation of the linear function.

Answer

A. -30 points

B. 60 points

Step-by-step explanation:

20 points for correct answer and 10 points deducted for wrong answer

Each deduction is -10 while each correct answer gives + 20

4 questions correctly and 11 incorrectly

= 4(20) + 11(-10)

= 80-110 = -30 points

Second round

7 correct, 8 incorrect

= 7(20) - 8(10)

= 140-80 = 60 points

Answer:

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

[tex]63\ \text{sq. units}[/tex]

Step-by-step explanation:

l = Length = [tex]\dfrac{x^2-x-6}{x-5}[/tex]

w = Width = [tex]\dfrac{x^2-6x+5}{x+2}[/tex]

Area is given by

[tex]A=lw\\\Rightarrow A=\dfrac{x^2-x-6}{x-5}\times\dfrac{x^2-6x+5}{x+2}\\\Rightarrow A=\dfrac{x^2-3x+2x-6}{x-5}\times\dfrac{x^2-5x-1x+5}{x+2}\\\Rightarrow A=\dfrac{(x-3)(x+2)}{x-5}\times\dfrac{(x-5)(x-1)}{x+2}\\\Rightarrow A=(x-3)(x-1)\\\Rightarrow A=x^2-4x+3[/tex]

Area of the room is [tex]x^2-4x+3[/tex].

If [tex]x=10[/tex]

Area of the room

[tex]A=x^2-4x+3=10^2-4\times 10+3\\\Rightarrow A=63\ \text{sq. units}[/tex]

So, the amount of carpet needed would be [tex]63\ \text{sq. units}[/tex].

Answer:

49

Step-by-step explanation:

Whenever you power something, you are just multiplying that number by itself amount of times you are powering

7 to the power of 2 is 7² = 49

The power (or exponent) of a number define how many times to use the number in a multiplication.

It is written as like a small number to the right and above the base number.

In this example the little "2" says to use 8 two times in a multiplication: 82 = 8 × 8 = 64.

To evaluate 7 to the power of 2.

7² = 7 × 7 = 49

Therefore, 7 to the power of 2 is 49.

Step-by-step explanation:

A continuación, presentamos la respuesta correcta al ejercicio citado:

En la regla de la potencia, durante el proceso de integración, se adiciona 1 al exponente, mientras que en la derivación se sustrae 1 a dicho exponente. De igual forma, el exponente pasa dividiendo mientras que en la derivación pasa multiplicando. Al último, agregamos la letra C, que significa constante.

Answer:

The value of a5 is 3125

Step-by-step explanation:

Recursive Sequence

It refers to the sequences where each term is given as a rule that depends on one or more of the previous terms, unlike explicit sequences where a general term is given and we can calculate any term without knowing the value of the previous terms, except for the first one.

The sequence is given as:

[tex]a_1=5[/tex]

[tex]a_n=-5a_{n-1}[/tex]

To find the value of a5, we need to find the previous terms first:

[tex]a_2=-5a_{1}=-5*5=-25[/tex]

[tex]a_3=-5a_{2}=-5*(-25)=125[/tex]

[tex]a_4=-5a_{3}=-5*125=-625[/tex]

[tex]a_5=-5a_{4}=-5*(-625)=3125[/tex]

The value of a5 is 3125

Answer:

V(x)=(x+9) * (3) * (2x + 6)

Step-by-step explanation:

A fish tank is usually made in the shape of a 3-Dimensional rectangular prism. The volume of this shape can be obtained by using the following formula

V = w * h * l

in this formula w represents the width, h represents the heigh, l represents the length, and V represents the volume of the rectangular prism/fish tank. Therefore, we can use the function provided in the question and simply add 3 units to the length and 2 units to the width in order for it to work for our new fish tank.

V(x)=(x+9) * (3) * (2x + 6)

Answer:

Fraction of saving = 1/8

Step-by-step explanation:

Given:

Spent on bills = 3/8

Spend on food = 2/5

Spend on entertainment = 1/10

Find:

Fraction of saving

Computation:

Fraction of saving = 1 - Spent on bills - Spend on food - Spend on entertainment

Fraction of saving = 1 - 3/8 - 2/5 - 1/10

By taking LCM

Fraction of saving = [40 - 15 - 16 - 4]/40

Fraction of saving = [5]/40

Fraction of saving = 1/8
