Answer:

1.67% approx

Step-by-step explanation:

To determine the experimental probability of landing on a number less than two when a number cube is tossed 60 times, we need to count the number of times the number on the cube is less than two and divide it by the total number of tosses.

Let's denote the event of landing on a number less than two as "A." We'll count the number of successful outcomes, where the number on the cube is less than two.

Assuming the number cube is fair and unbiased, it has six sides numbered from 1 to 6. Out of these, only one side has a number less than two, which is one.

Now, we can calculate the experimental probability using the formula:

Experimental Probability (P(A)) = Number of successful outcomes / Total number of tosses

In this case, the number of successful outcomes is the number of times the cube lands on a number less than two, which is one. The total number of tosses is given as 60.

Therefore, the experimental probability of landing on a number less than two is:

P(A) = 1 (successful outcomes) / 60 (total number of tosses)

= 1/60

≈ 0.0167 or 1.67%

So, the experimental probability of landing on a number less than two is approximately 0.0167 or 1.67%.

The equation of the parabola with focus (3, 4) and directrix y = 1 is [tex]x^2 - 6x - 12y + 57 = 0.[/tex]

To find the equation of a parabola with a given focus and directrix, we can use the standard form of the equation of a parabola:  

[tex]4p(y - k) = (x - h)^2[/tex]  

where (h, k) represents the coordinates of the vertex, and p is the distance between the vertex and the focus or directrix.

In this case, the focus is given as (3, 4), which means the vertex of the parabola will also be located at (3, 4).

The directrix is given as y = 1.

First, let's find the value of p, which is the distance between the vertex and the focus (or the vertex and the directrix). In this case, p will be the distance between the vertex (3, 4) and the directrix y = 1.

Since the directrix is a horizontal line, the distance between the vertex and the directrix is the vertical distance, which is |4 - 1| = 3.

Now that we have the value of p, we can substitute it into the equation:

[tex]4p(y - k) = (x - h)^2[/tex]

Plugging in the values (h, k) = (3, 4) and p = 3, we get:

[tex]4(3)(y - 4) = (x - 3)^2[/tex]

Simplifying further:

[tex]12(y - 4) = (x - 3)^2[/tex]

Expanding the equation:

[tex]12y - 48 = x^2 - 6x + 9[/tex]

Bringing all terms to one side:

[tex]x^2 - 6x - 12y + 57 = 0[/tex]

You should leave at 7:34 to catch the bus that comes at 8:05.

We have,

To catch the bus that arrives at 8:05, you should leave with enough time to reach the bus stop 31 minutes before the bus's arrival time.

To catch the bus that arrives at 8:05, you need to be at the bus stop before the bus arrives. Since it takes you 31 minutes to get to the bus stop, you should leave your starting point early enough to allow for that travel time.

By subtracting 31 minutes from the bus's arrival time of 8:05, you determine the time at which you should depart.

In this case, subtracting 31 minutes gives you 7:34, meaning you should leave at 7:34.

To calculate the departure time, subtract 31 minutes from the bus's arrival time:

= 8:05 - 31 minutes

= 7:34

Thus,

There are 27 chickens and 13 Rabbits in the pen on your grandmother's farm, based on the given information of 40 heads and 106 legs.

a) The unknowns in the problem are the number of chickens and rabbits in the pen. We don't know the exact quantities of each animal, which is what we need to determine.

b) Let's denote the number of chickens as "C" and the number of rabbits as "R." To represent the total number of animals in the pen, we can write the equation: C + R = total number of animals.

c) The total number of legs can be represented by the equation: 2C + 4R = total number of legs. This equation accounts for the fact that chickens have two legs, while rabbits have four.

d) To find the solution, we can use the given information: 40 heads and 106 legs. Since each animal has one head, the total number of animals is equal to the total number of heads, which is 40.

Using the equation C + R = 40, we can solve for one variable in terms of the other. For example, if we solve for C, we get C = 40 - R.

Substituting this value of C into the equation 2C + 4R = 106, we can solve for R:

2(40 - R) + 4R = 106

80 - 2R + 4R = 106

2R = 26

R = 13

Therefore, there are 13 rabbits in the pen.

To find the number of chickens, we can substitute the value of R into the equation C = 40 - R:

C = 40 - 13

C = 27

Hence, there are 27 chickens in the pen.

In conclusion, there are 27 chickens and 13 rabbits in the pen on your grandmother's farm, based on the given information of 40 heads and 106 legs.

The value of x is 4.

To determine the value of x, we can use the concept of similarity between shapes.

Similar shapes have corresponding sides that are proportional to each other.

Given the dimensions of the first shape as 5, x, and 5, and the dimensions of the second shape as 30, 24, and 30, we can set up the following proportion:

5/x = 30/24

To solve for x, we can cross-multiply:

30 · x = 5 · 24

30x = 120

Dividing both sides of the equation by 30:

x = 120 / 30

Given statement solution is :- The given expression √(-8 + 6i) does not have a real solution in the form w = a + bi, where a and b are real numbers.

To find the complex number in the form w = a + bi, where a and b are real numbers, we can solve the given expression.

Let's solve √(-8 + 6i) step by step:

First, we can express -8 + 6i in the form a + bi:

-8 + 6i = -8 + 6i + 0i = -8 + 6i + [tex]0i^2[/tex]

Now, we can take the square root of -8 + 6i:

√(-8 + 6i) = √((-8) + 6i + [tex]0i^2[/tex])

Since [tex]i^2[/tex] = -1, we can simplify the expression further:

√(-8 + 6i) = √(-8 - 6 + 6i)

= √(-14 + 6i)

Now, we want to express -14 + 6i in the form a + bi:

-14 + 6i = -14 + 6i + 0i = -14 + 6i +[tex]0i^2[/tex]

Taking the square root, we have:

√(-14 + 6i) = √((-14) + 6i + [tex]0i^2[/tex])

Since [tex]i^2[/tex] = -1, we can simplify the expression further:

√(-14 + 6i) = √(-14 - 6 + 6i)

= √(-20 + 6i)

Now, we want to express -20 + 6i in the form a + bi:

-20 + 6i = -20 + 6i + 0i = -20 + 6i + [tex]0i^2[/tex]

Taking the square root, we have:

√(-20 + 6i) = √((-20) + 6i + [tex]0i^2[/tex])

Since [tex]i^2[/tex] = -1, we can simplify the expression further:

√(-20 + 6i) = √(-20 - 6 + 6i)

= √(-26 + 6i)

Now, we want to express -26 + 6i in the form a + bi:

-26 + 6i = -26 + 6i + 0i = -26 + 6i +[tex]0i^2[/tex]

Taking the square root, we have:

√(-26 + 6i) = √((-26) + 6i + [tex]0i^2[/tex])

Since [tex]i^2[/tex] = -1, we can simplify the expression further:

√(-26 + 6i) = √(-26 - 6 + 6i)

= √(-32 + 6i)

We continue this process until we reach a point where the expression simplifies. However, in this case, we encounter an expression that cannot be simplified further, as the square root of a negative number is not defined in the set of real numbers.

Therefore, the given expression √(-8 + 6i) does not have a real solution in the form w = a + bi, where a and b are real numbers.

Answer:

Step-by-step explanation:

a. 2r + 5 = b because you have you have 5 more blue marbles than double the red *r= red and b=blue

b. to do the substitution you know that the red marbles plus the blue marbles add up to 77 so

b + r=77

now we can isolate for b and then substitute that value into the first equation

b=77-r and then this goes to 2r+5=77-r

c. now you just have to get like terms to their side of the equal sign

add r to both sides: 2r+r+5=77-r+r=  3r+5=77

and then you subtract 5 from both sides which makes 3r=72

to find r, divide both sides by 3

r=24

there are 24 red marbles

The new coordinates of the quadrilateral ABCD after the dilation is:

B' = (-8, -4)

C' = (4, -8)

D' = (0, 0)

We have,

To find the coordinates of the new quadrilateral after a dilation with a scale factor of 2 centered at the origin, we multiply the x and y coordinates of each point by the scale factor.

Given the original coordinates of the quadrilateral ABCD:

A = (-3, 3)

B = (-4, -2)

C = (2, -4)

D = (0, 0)

To dilate the coordinates with a scale factor of 2, we multiply each coordinate by 2:

A' = 2 x (-3, 3) = (-6, 6)

B' = 2 x (-4, -2) = (-8, -4)

C' = 2 x (2, -4) = (4, -8)

D' = 2 x (0, 0) = (0, 0)

The angle m∠HAT in the line segment is 54 degrees.

When line segment intersect, angle relationships are formed such as

vertical angles, linear angles etc.

Therefore,  the angle ∠HAT can be found using the relationship of the angles as follows:

m∠HAT = 2x + 6

Therefore,

m∠MAH + m∠HAT = 90 degrees

3x + 14 + 2x + 6 = 90

5x + 20 = 90

5x = 90 - 20

The number of different homework sets Mrs. Brown could assign can be calculated using the combination formula.

In this case, she wants to choose 8 problems out of 11 available problems. The formula for combinations is given by:
