Answer: 50% Chance
Answer: 1/2
Step-by-step explanation: 2,3, and 5 are the prime numbers 1-6. That means 3/6 of those numbers are prime. 3/6 simplifies to 1/2 or 50%
Answer:
5/12 or 41.66666% or 42%
Step-by-step explanation:
There are two number cubes both listed as 1-6. In order to find the probability of the total on both cubes being a prime number, you'd have to first come up with the prime numbers possible by addition. You should get 2, 3, 5, 7, and 11.
After finding the numbers possible, you have to find each of the different number combinations that you could use to get there. You should get 15 different possibilities.

1, 1
3:
1, 2
2, 1
5:

6, 1
2, 5
5, 2
3, 4
4, 3
11:
5, 6
6, 5
Now, you have to find the total possibilities. You should get 36.
1, 1
1, 2
1, 3
1, 4
1, 5
1, 6
2, 1

5, 4
5, 5
5, 6
6, 1
6, 2
6, 3
6, 4
6, 5
6, 6
Now all you have to do is divide the two numbers (15 and 36), and you should get 5/12 as an exact answer, or 41.66666 (repeating) %, which you can round up to 42%.

Researchers surveyed recent graduates of two different universities about their income. The following two-way table displays data for the sample of graduates who responded to the survey. Of graduates in the sample, what fraction came from university A?
https://gyazo.com/024c033fb3022b87aee5e6ca3695277b
75 graduates from University A had an income under $20,000.
From the two-way table, we can see that 35 graduates from University A had an income under $20,000. In addition, 40 graduates from University B had an income under $20,000. However, we should not simply add these two numbers together, as some graduates from each university may have been counted twice.
To avoid double counting, we need to look at the total number of graduates who responded to the survey. This number is 35 + 90 + 35 + 37 = 197. Therefore, we know that there were 197 unique graduates who responded to the survey.
Since there were 197 unique graduates and 40 graduates from University B had an income under $20,000, this means that there must have been 197 - 40 = 157 graduates from University A who responded to the survey.
Finally, we can see from the two-way table that 35 graduates from University A had an income under $20,000. Therefore, there were a total of 75 graduates from University A who had an income under $20,000.
Question
Researchers surveyed recent graduates of two different universities about their income. The following two-way table displays data for the sample of graduates who responded to the survey.

Circle C has a center at (-2,10) and contains the point P(10,5). Which equation represents circle C?
Answer: D.
Step-by-step explanation:
To solve this problem, you first need to find the distance between the center and the point on the circle. This will give you your radius.
There are 12 units between -2 and 10 on the x-axis.
There are 5 units between 5 and 10 on the y-axis.
To find the distance of the slope, you can treat the distance as the hypotenuse and the distances of the two sides as your variables.
Using the Pythagorean theorem:
12^2 + 5^2 = 13^2. Your radius is 13 units long.
The equation for a circle is shown as the following:
[tex](x - h)^{2} + (y - k)^{2} = r^2[/tex]
Where the center is (h, k), and the radius is r.
When the center is at (-2, 10) and the radius is 13, then the equation is shown here:
[tex](x +2)^2 + (y - 10)^2 = 169[/tex]
Answer: D

An airline ticket states that the flight takes 2 hours and 45 minutes. The flight time is actually 2 hours and 54 minutes. What is the percent error in the flight time?
Answer:
5.45%
Step-by-step explanation:
Given:
An airline ticket states that the flight takes 2 hours and 45 minutes.
The flight time is actually 2 hours and 54 minutes.
Question asked:
What is the percent error in the flight time?
Solution:
As we know:
[tex]Percent\ error=\frac{Experimental\ value - Theoretical\ value}{ Theoretical\ value}} \times100[/tex]
Theoretical value = 2 hours and 45 minutes
1 hour = 60 minutes
2 hours 45 minutes = 60 [tex]\times[/tex] 2 + 45 = 120 + 45 = 165 minutes
Experimental value = 2 hours and 54 minutes
1 hour = 60 minutes
2 hours 54 minutes = 60 [tex]\times[/tex] 2 + 54 = 120 + 54 = 174 minutes
[tex]Percent\ error=\frac{174-165}{165} \times100\\ \\ Percent\ error=\frac{9}{165} \times100\\ \\ Percent\ error=\frac{900}{165} \\ \\ Percent\ error=5.45[/tex]
Thus, the percent error in the flight time is 5.45%
Answer:
Step-by-step explanation:
Question asked:
What is the percent error in the flight time?
Solution:
As we know:
Theoretical value = 2 hours and 45 minutes
1 hour = 60 minutes
2 hours 45 minutes = 60 2 + 45 = 120 + 45 = 165 minutes
Experimental value = 2 hours and 54 minutes
1 hour = 60 minutes
2 hours 54 minutes = 60 2 + 54 = 120 + 54 = 174 minutes
Thus, the percent error in the flight time is 5.45%

hence solve the equation x^3+x^2-6x=0
The solution of the equation x³ + x² - 6x = 0 are x=0, x=2 and x=-3.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is x³ + x² - 6x = 0
x cube plus x square minus six times of x equal to zero.
Take x as common
x(x² + x - 6) = 0
Now factorize the equation within the parenthesis
x(x² + 3x - 2x - 6) = 0
x[x(x + 3) - 2(x + 3)] = 0
x(x - 2)(x + 3) = 0
Now
x = 0
x - 2 = 0 => x = 2
x + 3 = 0 => x = - 3

Final answer:
The equation [tex]x^3 + x^2 - 6x = 0[/tex]is factored into x(x + 3)(x - 2) = 0 to find the roots, which are x = 0, x = -3, and x = 2.
Explanation:
To solve the equation [tex]x^3 + x^2 - 6x = 0[/tex], we first recognize that the equation is not a quadratic, but a cubic equation. However, we can factor out an x, which simplifies the equation to [tex]x(x^2 + x - 6) = 0.[/tex]The cubic term now has been factored into a linear term and a quadratic term. The quadratic equation [tex]x^2 + x - 6[/tex] can be factored further into (x + 3)(x - 2).
The roots of the equation are the values of x that make the equation equal to zero. By setting each factor equal to zero, x = 0, x + 3 = 0, and x - 2 = 0, we find the solutions to be x = 0, x = -3, and x = 2.

In a science class, Paula made a mixture by adding 2.05 milliliters of
hydrogen peroxide and 6.15 milliliters of water together. Equal amounts of
the whole mixture were poured into 5 empty containers. How much of the
mixture, in milliliters, did she pour into each container?
Answer:
1.64 ml
Step-by-step explanation:
2.05 + 6.15 = 8.2
8.2 / 5 = 1.64
Paula poured 1.64 milliliters of the mixture into each of the 5 containers after combining the volumes of hydrogen peroxide and water to get a total volume of 8.20 milliliters.
Explanation:To find the amount of the mixture Paula poured into each container, we first need to calculate the total volume of the mixture she made by adding the volume of hydrogen peroxide to the volume of water.
The total volume of the mixture is 2.05 milliliters of hydrogen peroxide plus 6.15 milliliters of water, which equals 8.20 milliliters. Since the mixture was evenly distributed into 5 containers, we divide the total volume by the number of containers.
Amount per container = Total volume / Number of containers
Amount per container = 8.20 milliliters / 5 containers
Amount per container = 1.64 milliliters
Therefore, Paula poured 1.64 milliliters of the mixture into each container.

Find the sum and product of the roots.
3x^2 - 4x-7 = 0
x1,x2(-1, 7/3)
to slove this you need the formula
from equation a=3 b=-4 c=7;
x=(-b±√b²-4ac)/2a
x=(4±√-4²-4×3×7)/2×3
x=(4±√100)/6
x=(4±10)/6
x1=4-10/6 x2=4+10/6
x1=-6/6 x2=14/6
x1=-1 x2=7/3
The sum of roots is 4/3, and the product of roots is -7/3 for the quadratic equation [tex]3x^2[/tex] - 4x - 7 = 0.
To find the sum and product of the roots of the quadratic equation [tex]\(3x^2 - 4x - 7 = 0\)[/tex], we can use Vieta's formulas.
Vieta's formulas state that for a quadratic equation of the form [tex]\(ax^2 + bx + c = 0\),[/tex] the sum of the roots [tex](\(r_1\) and \(r_2\))[/tex] is given by [tex]\(-\frac{b}{a}\),[/tex] and the product of the roots is given by [tex]\(\frac{c}{a}\).[/tex]
In your equation, [tex]\(a = 3\), \(b = -4\), and \(c = -7\).[/tex]
So, the sum of the roots [tex](\(r_1\) and \(r_2\)) is:[/tex]
[tex]\[r_1 + r_2 = -\frac{b}{a} = -\frac{-4}{3} = \frac{4}{3}\][/tex]
And the product of the roots [tex](\(r_1\) and \(r_2\)) is:[/tex]
[tex]\[r_1 \cdot r_2 = \frac{c}{a} = \frac{-7}{3}\][/tex]
So, the sum of the roots is [tex]\(\frac{4}{3}\)[/tex], and the product of the roots is [tex]\(\frac{-7}{3}\).[/tex]

What is the y- intercept of
y= 3 - 4x
The y-intercept of the equation y=3-4x is the constant term, which is 3. Hence, the line crosses the y-axis at the point (0, 3).
Explanation:The y-intercept of the equation y = 3 - 4x can be found by looking at the constant term in the equation, which is the term without the 'x'. In this case, the constant term is 3. Therefore, the y-intercept of the line is the point (0, 3) where the line crosses the y-axis; that is when x=0, y=3.
In the linear equation \(y = 3 - 4x\), the y-intercept occurs when \(x = 0\). To find the y-intercept, substitute \(x = 0\) into the equation:
\[ y = 3 - 4(0) \]
This simplifies to \(y = 3\). Therefore, the y-intercept is \(y = 3\). In terms of interpretation, the y-intercept represents the point where the graph intersects the y-axis, indicating that when x is zero, the corresponding y-value is 3. So, the y-intercept for this equation is the point (0, 3) on the coordinate plane.

Luke has 4 more than triples the number of model cars that Andrew has. Luke has 31 cars. How many cars does Andrew have? {Write and solve an equation}
Answer:
Andrew has 9 cars
Step-by-step explanation:
Let's start by defining what our unknowns are and how to name them:
For the number of cars Andrew has: let's use the letter A
For the number of cars Luke has: let's use the letter L
Not write the first sentence in mathematical terms:
"Luke has 4 more than triples the number of cars that Andrew has."
L = 3 * A + 4
The second phrase results on a very simple equation since it just states the number of cars that Luke has:
L = 31
Now we can combine these two equations by replacing the variable "L" in the first equation with the second equation and then solve for A:
L = 3 * A + 4
31 = 3 * A +4
31 - 4 = 3 * A
27 = 3 * A
A = 27/3
A = 9
Therefore, Andrew has 9 cars.

a recipe calls for 5 tablespoons of orange juice a can of orange juice is 11 fluid ounces how many tablespoons of juice are in a can
By using the conversion factor that 1 fluid ounce is equal to 2 tablespoons, an 11 fluid ounce can of orange juice contains 22 tablespoons of juice.
Explanation:To find out how many tablespoons of juice are in a can, we will use the given conversion factors. We know that 1 fluid ounce (fl oz) is equivalent to 2 tablespoons (tbsp). The can contains 11 fluid ounces of orange juice.
Multiply the number of fluid ounces in the can by the number of tablespoons per fluid ounce to find the total tablespoons in the can: 11 fl ozTherefore, there are 22 tablespoons of orange juice in a can.
A paint can has a radius of 4 inches and a height of 15 inches. What is the volume of the paint can? Round to the nearest tenth.
Use 3.14 for
cubic inches
Answer:
[tex]V=753.6\ \text{inches}^3[/tex]
Step-by-step explanation:
Given that,
Radius of a paint can, r = 4 inches
Height of a paint can, h = 15 inches
We need to find the volume of the paint can. We know that the shape of a paint can is in the form of cylinder such that the volume of cylinder is given by :
[tex]V=\pi r^2h[/tex]
Substituting all the values we get
[tex]V=3.14\times (4)^2\times 15\\\\V=753.6\ \text{inches}^3[/tex]
So, the volume of the paint can is 753.6 cubic inches.

Final answer:
An extraneous solution is a value that arises from the algebraic method of solving but is NOT a solution of the original equation.
Explanation:
An extraneous solution is a value that arises from the algebraic method of solving but is NOT a solution of the original equation. Extraneous solutions can occur when certain algebraic manipulations are performed that introduce additional solutions that are not valid in the context of the problem. For example, if we square both sides of an equation, we may introduce extraneous solutions. These extraneous solutions need to be identified and discarded when solving equations.
