Answer:

3/8

Step-by-step explanation:

For each of the 3 balls, there are 4 options of baskets to put the ball.

The Probability is 3/4.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Total sample space for 3 balls= 4 x 4 x 4 = 64

So, Favorable events such that a basket has 3 balls = (\(^4C_1\)) x (\(^3C_1\))

Favorable events such that a basket has 4 balls = (\(^4C_1\))

Then,

= 1- Probability that any basket has 3 or 4 balls

= 1- ((\(^4C_1\)) x (\(^3C_1\)) +  (\(^4C_1\))) / (4 x 4 x 4)

= 1- ((4!/ 3!) x (3!/2!) + (4!/3!) / 64

= 1- (12 + 4)/ 64

= 1- 16/64

= 1-1/4

= 3/4

Hence, the probability is 3/4

Answer:

C and D have the same slope of 1

Answer: The function would have a minimum value because the least you will ever have is 0$. It cannot go below 0, so that is the minimum. However, depending on how much time has passed, the maximum amount of money you have can change. It can always go up more, so there is no set maximum.

Step-by-step explanation:

The true statement based on the relationship depicted in the Venn diagram is that no rhombuses are trapezoids (option D).

To identify the true statement using the relationship represented in the Venn diagram, we need to analyze the overlapping regions and the properties of the shapes involved.

A trapezoid is a quadrilateral with at least one pair of parallel sides, while a rhombus is a quadrilateral with all sides of equal length. Let's evaluate the options:

A. All trapezoids are rhombuses: This statement is not true based on the diagram. The overlapping region between the trapezoids and rhombuses shows that there are trapezoids that are not rhombuses. Therefore, option A is incorrect.

B. All rhombuses are trapezoids: This statement is true based on the diagram. The entire region representing rhombuses is also included within the region representing trapezoids. Every rhombus can be considered a trapezoid because it has at least one pair of parallel sides. Thus, option B is correct.

C. No trapezoids are rhombuses: This statement is not true based on the diagram. The overlapping region indicates that there are trapezoids that are indeed rhombuses. Therefore, option C is incorrect.

D. No rhombuses are trapezoids: This statement is true based on the diagram. There is no overlap between the regions representing rhombuses and trapezoids, implying that no rhombus can be considered a trapezoid. Hence, option D is correct.

Answer:

The slope is \(\frac{4}{5}\)

Step-by-step explanation:

Hi there!

We are given the points (-1, -1) and (-6, -5).

We want to find the slope between them.

We can use the slope formula for this, which is \(\frac{y_2-y_1}{x_2-x_1}\), where \((x_1, y_1)\) and \((x_2, y_2)\) are points

We do have two points, which is what we need to find the slope, but let's label their values to avoid any confusion.

\(x_1=-1\\y_1=-1\\x_2=-6\\y_2=-5\)

Now substitute those values into the slope formula (m is the slope, and remember: the formula contains SUBTRACTION, even though we have negative numbers):

m=\(\frac{y_2-y_1}{x_2-x_1}\)

m=\(\frac{-5--1}{-6--1}\)

Simplify:

m=\(\frac{-5+1}{-6+1}\)

m=\(\frac{-4}{-5}\)

Divide again:

m=\(\frac{4}{5}\)

The slope is \(\frac{4}{5}\)

Hope this helps!

Answer:

Now first we have to found the decrease length.

which is:4mm-3mm=1mm

Now

we have to use formula to calculate the percentage which is

= decrease length/total length ×100%

=. 1/4×100%

=. 25 %

Therefore,the decrease rate is 25%.

The volume of a cube is given by

Since the lenght in this case is 3 cm, each cube has a volume of:

Now, the combined volume is the sum of the volume of each cube.

Therefore, the combined volume of the cubes is 54 cm^3.

The amount of the element, Francium, that will remain after 2 hours is 31.25 grams.

To determine how much francium will be left after 2 hours, we need to calculate the number of half-lives that occur within that time period.

Given that the half-life of francium is 22 minutes, we can calculate the number of half-lives in 2 hours (120 minutes):

Number of half-lives = (Total time elapsed) / (Half-life)

Number of half-lives = 120 minutes / 22 minutes ≈ 5.4545

Since we can't have a fraction of a half-life, we take the integer part, which is 5.

Each half-life represents a halving of the amount of francium. So, after 5 half-lives, the remaining amount of francium can be calculated using the formula:

Remaining amount = Initial amount * (1/2)^(Number of half-lives)

Given that the initial amount is 1000 grams, we can calculate the remaining amount after 2 hours:

Remaining amount = 1000 grams * \((1/2)^5\)

Remaining amount ≈ 1000 grams * 0.03125

Remaining amount ≈ 31.25 grams

Therefore, after 2 hours, approximately 31.25 grams of francium will be left.

Answer:

{x,y} = {1,1}

Step-by-step explanation:

// Solve equation [2] for the variable  x

 [2]    3x = 4y - 1

 [2]    x = 4y/3 - 1/3

// Plug this in for variable  x  in equation [1]

  [1]    3•(4y/3-1/3) + 4y = 7

  [1]    8y = 8

// Solve equation [1] for the variable  y

  [1]    8y = 8

  [1]    y = 1

// By now we know this much :

Step-by-step explanation:

when x=2, 11x+6 = 22+6=28,

2x+28x+48= 30x+48=60+48=108

when x=-3, 11x+6 = -33+6=-27,

2x+28x+48= 30x+48=-90+48=-42

Answer:

I got 28, -27, 108, and -42. See explanation for the answer for which problems

Step-by-step explanation:

11x + 6 = ?

2x + 28x + 48 = ?

x = 2 and x = -3

Let's start with the first equation

Using x = 2

11(2) + 6 = ?

22 + 6 = 28

Using x = -3

11(-3) + 6 =?

-33 + 6 = -27

Second equation

Using x = 2

2(2) + 28(2) + 48 = ?

4 + 56 + 48 = 108

Using x = -3

2(-3) + 28(-3) + 48 = ?

-6 - 84 + 48 = -42

The denominator is zero (0/0 is undefined), we cannot determine the exact value of f(-3) using this equation.

To solve the given equations, we need to find the value of the function f(x) for specific values of x.

"If f(x) / (x - 2) = x³ + 2x - 4 + 13/(x - 2), what is f(2)?"

To find f(2), we can substitute x = 2 into the equation and solve for f(2).

Plugging in x = 2, we get:

f(2) / (2 - 2) = 2³ + 2(2) - 4 + 13/(2 - 2)

Since the denominator is zero (2 - 2 = 0), the equation is undefined. Therefore, there is no solution for f(2) in this case.

"If f(x) / (x + 3) = 3x² - 4x + 2, what is f(-3)?"

To find f(-3), we can substitute x = -3 into the equation and solve for f(-3).

Plugging in x = -3, we get:

f(-3) / (-3 + 3) = 3(-3)² - 4(-3) + 2

Simplifying, we have:

f(-3) / 0 = 3(9) + 12 + 2

f(-3) / 0 = 27 + 12 + 2

f(-3) / 0 = 41

To find all points on the x-axis that are 16 units away from the point (5, -8), we can use the distance formula. The distance between two points (x₁, y₁) and (x₂, y₂) is given by the formula:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

In this case, the y-coordinate of the point (5, -8) is -8, which lies on the x-axis. So, any point on the x-axis will have a y-coordinate of 0. Let's substitute the given values and solve for the x-coordinate.

d = √((x - 5)² + (0 - (-8))²)

Simplifying:

d = √((x - 5)² + 64)

Now, we want the distance d to be equal to 16 units. So, we set up the equation:

16 = √((x - 5)² + 64)

Squaring both sides of the equation to eliminate the square root:

16² = (x - 5)² + 64

256 = (x - 5)² + 64

Subtracting 64 from both sides:

192 = (x - 5)²

Taking the square root of both sides

√192 = x - 5

±√192 = x - 5

x = 5 ± √192

Therefore, the two points on the x-axis that are 16 units away from the point (5, -8) are:

Point 1: (5 + √192, 0)

Point 2: (5 - √192, 0)

In summary, the points on the x-axis that are 16 units away from the point (5, -8) are (5 + √192, 0) and (5 - √192, 0).
