Answer:

A.) 5 employees

D.) 9 miles or less

Step-by-step explanation:

Frequent Flier Miles(000) ____ Frequency

0 up to 3 __________________ 5

3 up to 6 __________________ 12

6 up to 9 __________________ 23

9 up to 12 __________________ 8

12 up to 15 _________________ 2

Total ______________ 50

Required:

a. How many employees accumulated less than 3,000 miles?

5 employees (from the frequency table)

b. Convert the frequency distribution to a cumulative frequency distribution.

Frequent Flier Miles(000) ____ F ____ cumm/F

0 up to 3 __________________ 5 ____ 5

3 up to 6 __________________ 12 ___ 17

6 up to 9 __________________ 23 __ 40

9 up to 12 __________________ 8 __ 48

12 up to 15 _________________ 2 __ 50

c. Portray the cumulative distribution in the form of a cumulative frequency polygon.

d. Based on the cumulative frequency polygon, about 75 percent of the employees accumulated how many miles or less?

75% of employees

(75 / 100) * total number of employees

0.75 * 50

= 37.5

From the Cummulative frequency polygon, 75% of the employees accumulated about 9 miles or less

Step-by-step explanation:

We are going to express

y in terms of x.

=> 2x + 3y = -4, y = (-4 - 2x)/3.

By Vieta's Formula,

We have SOR = -b/a and POR = c/a.

=> x + y = -7/6, xy = k/6.

When x + y = -7/6,

x + (-4 - 2x)/3 = -7/6.

=> (x - 4)/3 = -7/6

=> (x - 4) = -7/2

=> x = 4 - 7/2

=> x = 0.5.

When xy = k/6,

x(-4 - 2x)/3 = k/6.

Hence k = 6[x(-4 - 2x)/3]

= 2x(-4 - 2x) = 2(0.5)(-4 - 2(0.5)) = -5.

The value of k is -5.

Answer:

[tex]k = -5[/tex]

Step-by-step explanation:

We have the quadratic equation:

[tex]6x^2+7x+k=0[/tex]

Where x and y are the roots of the equation and:

[tex]2x+3y=-4[/tex]

First, using the quadratic formula with a = 6, b = 7, and c = k, we can find the roots to be:

[tex]\displaystyle x=\frac{-(7)\pm\sqrt{(7)^2-4(6)(k)}}{2(6)}[/tex]

Simplify:

[tex]\displaystyle x=\frac{-7\pm\sqrt{49-24k}}{12}[/tex]

So, our two roots are:

[tex]\displaystyle x=\frac{-7+\sqrt{49-24k}}{12}\text{ and } y=\frac{-7-\sqrt{49-24k}}{12}[/tex]

For our first root, we can multiply both sides by 2.

And for our second root, we can multiply both sides by 3.

So, this produces:

[tex]\displaystyle 2x=\frac{-7+\sqrt{49-24k}}{6}\text{ and } 3y=\frac{-7-\sqrt{49-24k}}{4}[/tex]

Since we are given that:

[tex]2x+3y=-4[/tex]

By substitution:

[tex]\displaystyle \Big(\frac{-7+\sqrt{49-24k}}{6}\Big)+\Big(\frac{-7-\sqrt{49-24k}}{4}\Big)=-4[/tex]

Remove the fractions by multiplying both sides by 12:

[tex]\displaystyle (-14+2\sqrt{49-24k})+(-21-3\sqrt{49-24k})=-48[/tex]

Combine like terms:

[tex]-35-\sqrt{49-24k}=-48[/tex]

Adding 35 to both sides produces:

[tex]-\sqrt{49-24k}=-13[/tex]

So:

[tex]\sqrt{49-24k}=13[/tex]

Squaring produces:

[tex]49-24k=169[/tex]

Therefore:

[tex]-24k=120\Rightarrow k=-5[/tex]

Hello!

[tex]\boxed{ \bf d.~0.75g~+~6~≤~30}[/tex]

The variable “g“ represents games, so the coefficient in front of it CANNOT be 6 (since $6 is the cost of the admission and you only have to pay it once).

This automatically eliminates options A and B.

We are now left with C and D.

Since the questions asks for the possible number of games played with $30, we cannot go above it. Therefore, this eliminates option C because that sign is basically telling us that the cost of the admission fee ($6) + the number of games is either greater than or equal to $30. We need it to be LESS than or EQUAL to $30.

Step-by-step explanation:

Since polygon KLMN and polygon PQRS are similar, it follows that their corresponding side lengths would be proportional to each other. Therefore:

LM/QR = KL/PQ

Plug in the values

x/20 = 12/30

Multiply both sides by 20

x = (12*20)/30

9x=81

9x/9=81/9

x=9

Option C is correct, the solution of 9x = 81 is x=9.

Two or more expressions with an Equal sign is called as Equation.

The given equation is 9x=81

Nine times of x equal to eighty one.

We have to solve for x

Divide both sides by 9

x=81/9

Divide numerator and denominator by 9

x=9

Hence, Option C is correct, the solution of 9x = 81 is x=9.
