Answer:

The discriminant of the quadratic equation is -7.

Step-by-step explanation:

We are given the following quadratic equation in the question:

[tex]x^2+x+2 = 0[/tex]

Comparing to general quadratic equation:

[tex]ax^2+bx+c = 0\\a = 1\\b = 1\\c = 2[/tex]

We have to find the discriminant of the quadratic equation.

Formula:

[tex]d = b^2-4ac[/tex]

Putting values, we get,

[tex]d = (1)^2 - 4(1)(2) = 1 - 8 = -7[/tex]

Thus, the discriminant of the quadratic equation is -7.

Answer:

d. 7.3

Step-by-step explanation:

-16-10.2g = -14.7g + 16.85

4.5g = 32.85

g = 7.3

The solution for the equation -16 - 10.2g = -14.7g + 16.85 is g = 7.3. You can verify it by substituting the solution back into the original equation.

To solve the given equation, -16 - 10.2g = -14.7g + 16.85, we must first isolate the variable, g, by moving all terms involving g to one side of the equation and constant terms to the other side. Add 10.2g to both sides of the equation, giving,  -16 = -4.5g + 16.85. To further isolate g, subtract 16.85 from both sides resulting in -32.85 = -4.5g. Finally, divide by -4.5 to solve for g. Thus, g = -32.85 / -4.5 = 7.3. We verify our solution by substituting 7.3 back into the original equation and confirming that the equality holds true.

Answer:

see below

Step-by-step explanation:

We need to find the diameter of the square

We can find this using the Pythagorean theorem

a^2+b^2 = c^2  where the legs are 7 and 7 and the diameter is c

7^2 +7^2 = c^2

49+49 = c^2

98 = c^2

Taking the square root of each side

sqrt(98) = sqrt(c^2)

9.899494937 = c

Since 9.9 is less than 11 which is the diameter of the circle it will never touch the circle.

Since the longest part of the square is less than the diameter of the circle, the square will fit  inside the circle without touching

Answer:

Diagonal < Diameter

Step-by-step explanation:

The square will fit inside without touching if the diagonal length is less than the diameter

Diagonal = sqrt(7² + 7²)

7sqrt(2)

Diameter = 11

7sqrt(2) < 11

Because

(7sqrt(2))² < 11²

98 < 121

Step-by-step explanation:

Given the cost of a customers smartphone bill,

C=10g+50

We are required to factor the polynomial.

First, determine the G.C.D of both terms

Next, we divide each of the term by 10 and balance it by multiplying the expression by 10.

[tex]C=10g+50\\=10(\frac{10g}{10}+\frac{50}{10})\\C=10(g+5)[/tex]

Answer:

45.8

Step-by-step explanation:

We can use the Pythagorean theorem with legs 3x and 4x+7

a^2+ b^2 = c^2

(3x^2) +(4x+7)^2 = c^2

Let x = 8

(3*8)^2 + (4*8+7)^2 = c^2

24^2+ 39^2 = c^2

576+1521 = c^2

2097 = c^2

Take the square root of each side

sqrt(2097) = sqrt(c^2)

45.79301257 =c

Rounding to the nearest tenth

45.8 =c

Answer:

45.8

Step-by-step explanation:

First solve for the other two sides by replacing x with 8

4(8)+7 = 39

3(8) = 24

Then use the pythagorean theorem ([tex]a^{2} + b^{2} = c^{2}[/tex]) to solve for the hypotenuse, c being the hypotenuse

[tex]39^{2} + 24^{2} = c^{2}[/tex]

1521 + 576 = [tex]c^{2}[/tex]

2097 = [tex]c^{2}[/tex]

Answer:

C, y = 1.2x

Step-by-step explanation:

Notice that x, representing time, is multiplied by 1.2 each time to get y, representing the number of problems. You can find this out by dividing y by x. 36/30 = 1.2.

48/40 = 1.2.

And so on...

P.S.: If you ever come across a problem like this, subtract one y value by another y value, then subtract the corresponding x values from eachother, then make both numbers into one fraction with y as the numerator and x as the denominator. In this problem, that would look like this:  

48 and 36 are both y values: 48 - 36 = 12

40 and 30 are the corresponding x values: 40 - 30 = 10

We get 12/10, which can be simplified to 1.2. The slope is 1.2.

This method will always work for a straight line and will be taught to you soon if you haven't learned it already.

Answer:

a. 40/250

b. 70/250

c. Preferring diet soda and preferring hamburgers are not independent events

d.  Preferring regular soda and preferring hot dogs are not independent events

Step-by-step explanation:

We are given:

                      Regular Soda    Diet Soda    Total

Hamburgers             90                 40            130

Hot Dogs                   70                 50           120

Total                          160                90          250

a. The probability that someone who prefers diet soda will also prefer hamburgers can be calculated as:

No. of people who prefer hamburgers and diet soda / Total no. of people

40/250

b. The probability that someone who prefers hot dogs will also prefer regular soda can be calculated as:

No. of people who prefer hot dogs and regular soda/Total no. of people

70/250

c. For two events to be independent, they must fulfill the condition:

P(A and B) = P(A) * P(B)

P(Diet Soda) = No. of people who prefer diet soda/total no. of people

                     = 90/250

P(Hamburgers) = No. of people who prefer hamburgers/total no. of people

                     = 130/250

P(Diet Soda and Hamburgers) = 40/250

Now, we need to check:

P(Diet Soda and Hamburgers) = P(Diet Soda) * P(Hamburgers)

40/250 = 90/250 * 130/250

40/250 ≠ 11700/62500

So, we can conclude that these two events are not independent events.

d. P(Regular Soda) = No. of people who prefer regular soda/total no. of people

                     = 160/250

   P(Hot dogs) = No. of people who prefer hot dogs/total no. of people

                     = 120/250

P(Regular Soda and Hot Dogs) = 70/250

Now, we need to check if:

P(Regular Soda and Hot Dogs) = P(Regular Soda) * P(Hot dogs)

70/250 ≠ 160/250 * 120/250

So, these two events are not independent.

The solutions obtained are Part (a): The probability is 0.444, Part (b): The probability is 0.583, Part (c): Preferring diet soda and preferring hamburgers are not independent and Part (d): Preferring regular soda and preferring hot dogs are not independent.

Probability and Independence Analysis

Let's analyze the data provided from Manuela and Stephen's survey:

Regular Soda Diet Soda Total

Hamburgers 90 40 130

Hot Dogs 70 50 120

Total         160 90 250

→ Part A: Probability that Someone Who Prefers Diet Soda Also Prefers Hamburgers

The number of people who prefer diet soda is 90, and among them, 40 prefer hamburgers. Therefore, the probability is calculated as follows:

P(Hamburgers|Diet Soda) = 40 / 90

                                          ≈ 0.444

→ Part B: Probability that Someone Who Prefers Hot Dogs Also Prefers Regular Soda

The number of people who prefer hot dogs is 120, and among them, 70 prefer regular soda. Therefore, the probability is:

P(Regular Soda|Hot Dogs) = 70 / 120

                                            ≈ 0.583

→ Part C: Independence of Preferring Diet Soda and Preferring Hamburgers

To determine if these events are independent, we check if:

P(Diet Soda AND Hamburgers) = P(Diet Soda) * P(Hamburgers)

Calculations:

→ P(Diet Soda AND Hamburgers) = 40 / 250

→ P(Diet Soda) = 90 / 250

→ P(Hamburgers) = 130 / 250

→ P(Diet Soda AND Hamburgers) ≠ P(Diet Soda) * P(Hamburgers)

Since the equality does not hold, these events are not independent.

Part D: Independence of Preferring Regular Soda and Preferring Hot Dogs

We test the same independence condition for regular soda and hot dogs:

→ P(Regular Soda AND Hot Dogs) = P(Regular Soda) * P(Hot Dogs)

Calculations:

→ P(Regular Soda AND Hot Dogs) = 70 / 250

→ P(Regular Soda) = 160 / 250

→ P(Hot Dogs) = 120 / 250

→ P(Regular Soda AND Hot Dogs) ≠ P(Regular Soda) * P(Hot Dogs)

Therefore, these events are also not independent.

Final answer:

To find the total earnings for Wanda's highest two consecutive quarters of employment, multiply her weekly unemployment compensation by the number of weeks in two quarters.

Explanation:

To find the total earnings for Wanda's highest two consecutive quarters of employment, we need to compare the given state and weekly unemployment compensation with the table provided. According to the table, the maximum weekly unemployment compensation for Oregon is $330. Since Wanda's weekly compensation is $360, it means that her state is Oregon. Now, we can find the total earnings for her highest two consecutive quarters by multiplying her weekly compensation by the number of weeks in two quarters (26 weeks).

$360 times 26 (*) = $9360

Therefore, the total 26-week earnings for Wanda's highest two consecutive quarters of employment is $9360.
