last question:) thanks guys​

Based on the frequency table given,

a) The minimum number of dogs that could have a mass of more than 26 kg is of: 5.

b) The maximum number of dogs that could have a mass of more than 26 kg is of: 16.

The frequency table displays the number of times each value, or range of values, appears in the data-set.

where 11 weights are between 20 and 30,  and all of the dogs in the interval 20 × 30 have weights less than 26 kg, the lowest number of dogs that might have a mass more than 26 kg is 5.

This  implies that only the dogs in the period 30 x 40 would have a mass greater than 26 kg.

In linear equation ,The truck's relative position with respect to the car is 100 feet

What is linear equation ?

If the truck is moving at a seed "V" then its position after 8 seconds is going to be:

XT = V* t = V * 8 = 8 V

The car, which is initially 60 feet ahead of the truck and starts moving at 5 m/s faster than the truck, would have a speed given by: V + 5

And its position (relative to the truck's) would be:

XC = 60 + (V + 5) * t = 60 + (V + 5) * 8 = 60 + 40 + 8 V = 100ft + 8 V

then the position of the truck relative to that of the car would be given by the difference:

XT - XC = 8 V - (100 +8 V) = 8 V - 8 V - 100ft = -100 feet

Let W be the set of all vectors

\(\left[\begin{matrix}b-2d\\ 5b+d\\ b+3d\\ d\end{matrix}\right]\)

where b and d are real.

We can write the matrix as;

\(\left[\begin{matrix}b-2d\\ 5b+d\\ b+3d\\ d\end{matrix}\right]=b\left[\begin{matrix}1\\ 5\\ 1\\ 0\end{matrix}\right]+d\left[\begin{matrix}-2\\ 1\\3\\ 1\end{matrix}\right]\)

Remember that if aα + bβ ∈ W, ∀ α, β ∈ W and a, b are scalers, then W is a vector space. Let,

\(\alpha=\left[\begin{matrix}1\\ 5\\ 1\\ 0\end{matrix}\right],\beta=\left[\begin{matrix}-2\\ 1\\3\\ 1\end{matrix}\right]\)

These are independent vectors.

The equation of a line describing Carla's motion during the race is                        y = 3x - 5.        

The slope is defined as the rate of change of the y-axis with respect to the x-axis.

As we are representing y as distance in meters and x as time in seconds we can form two co-ordinates for the distance Carla covered, They are

(20,55) and (30,85).

Now to form an equation of a line we have to first determine the slope(m) and y-intercept (b).

We know slope(m) = (y₂-y₁)/(x₂-x₁).

∴ Slope(m) = (85 - 55)/(30 -20).

= 30/10.

= 3.

Now, The equation of this line can be written as slope intercept form as        y = mx + b.

55 = 3(20) + b.

b = -5.

So, y = 3x - 5 is our required equation of this situation represented by a line.

The table of integrals can be a useful tool for simplifying the integration process, but it's important to have a solid understanding of calculus concepts in order to use it effectively.

The table of integrals is a tool used in calculus to simplify the process of finding antiderivatives. It lists various functions and their corresponding antiderivatives, or integrals.

To use the table of integrals, you first need to identify the function you are trying to integrate. Then, find a similar function in the table and use the corresponding antiderivative to solve your integral.

It's important to note that not all functions have a corresponding antiderivative listed in the table, and in those cases, other integration techniques must be used.

Additionally, it's always a good idea to double check your work and make sure the answer makes sense in the context of the original problem.

If we use the table of integrals, the solution would be In | tan(x+7) + sec(x+7)|+C. Option A

Using the table of integral, we say

∫ (1/cos(x +7)) dx ⇒ ∫sec (x+7) dx

u = x+7   ⇒ du = dx

= ∫sec (u) du

Expand the fraction by tan (u) + sec (u)

= ∫(sec(u) (tan(u) + sec (u))/ tan (u) + sec (u)

= ∫((sec(u) tan(u) + sec²(u))/ (tan (u) + sec (u))) du

Substitute v= tan(u) + sec (u) ⇒ dv = (sec(u) tan(u) + sec²(u))du

= ∫(i/v)dv

= In(v)

Undo substitution v = tan(u) + sec(u)

=In(tan(u) + sec(u))

The correct options for the frequency table problem is -

D. Categories are descriptions of​ data, such as which grades students received on a test or the heights of trees in a forest. They can describe qualities or represent counts or measurements. The frequency of a category is the number of data values in the category.

What is frequency table?

A frequency table is just a two-column "t-chart" or table that lists all of the potential outcomes and their corresponding frequencies as seen in a sample.

D. Categories are descriptions of data, such as which grades students received on a test or the heights of trees in a forest.

They can describe qualities or represent counts or measurements.

The frequency of a category is the number of data values in the category.

A frequency table is a table that displays the categories or groups of a set of data along with their corresponding frequencies.

The categories are typically represented in the left column, and the frequencies are listed in the right column.

The categories represent the possible values or ranges of values that the data can take.

For example, in a frequency table of student grades on a test, the categories might be "A," "B," "C," "D," and "F."

The frequency of a category is the number of times that the data falls within that category.

For example, if there are 20 students in a class and 5 of them received an "A" on a test, then the frequency of the "A" category would be 5.

Relative frequency is the proportion or percentage of observations in a category relative to the total number of observations.

It is calculated by dividing the frequency of a category by the total number of observations.

For example, if there are 20 students in a class and 5 of them received an "A" on a test, then the relative frequency of the "A" category would be 5/20 = 0.25 or 25%.

Cumulative frequency is the running total of frequencies for a set of data.

For example, if the frequency of the "A" category is 5 and the frequency of the "B" category is 10, then the cumulative frequency of the "B" category would be 5 + 10 = 15.

It represents the total number of observations that fall within a category and all previous categories.

The volume of the tower is 224 in³, which is not listed among the given options.

To find the volume of the rectangular block, we need to multiply its length, width, and height. Therefore, the volume of the single block is:
8 x 3.5 x 2 = 56 cubic inches.
Since we are stacking four blocks to create a tower, we need to multiply the volume of a single block by 4.

Thus, the volume of the tower is:
56 x 4 = 224 cubic inches.
The volume of a rectangular block can be found using the formula,

V = length × width × height.

In this case, the length is 8 inches, the width is 3.5 inches, and the height is 2 inches.

V = 8 × 3.5 × 2 V

= 28 × 2 V

= 56 in³

Now that we know the volume of one block, we can find the volume of the tower created by stacking four blocks. Tower volume = block volume × number of blocks Tower volume = 56 in³ × 4 Tower volume = 224 in³

Answer

There are 20 black marbles in the bag.

There are 30 red marbles in the bag.

Explanation

The bag contains 50 red and black marbles.

Let the number of red marbles be x

Let the number of black marbles be y

x + y = 50

Then, for every 3 red marbles, there are 2 black marbles

3 red marbles = 2 black marbles

x red marbles = y black marbles

We can write a mathematical relationship by cross multiplying

3 × y = 2 × x

3y = 2x

2x = 3y

Divide both sides by 2

(2x/2) = (3y/2)

x = 1.5y

We can now write the two equations together

x + y = 50

x = 1.5y

We can substitute for x in the first equation

x + y = 50

x = 1.5y

1.5y + y = 50

2.5y = 50

Divide both sides by 2.5

(2.5y/2.5) = (50/2.5)

y = 20 black marbles.

x + y = 50

x = 50 - y = 50 - 20 = 30 red marbles.

The trigonometric ratios for the angle α formed by the terminal side and the x-axis indicates;

sin(α) = -1

cos(α) = 0

tan(α) = ∞

cot(α) = 0

sec(α) = ∞

csc(α) = -1

The trigonometric ratios are equations that express the relationship between the interior angle of a right triangle and two of the sides of the triangle.

The values of the six trigonometric functions for the measure of an angle that passes through the point (0, -2) can be found using the definition of the trigonometric functions as follows;

sin(θ) = (Length of opposite side)/(Length of the hypotenuse side)

cos(θ) = (Length of adjacent side)/(Length of the hypotenuse side)

tan(θ) = (Length of opposite side)/(Length of adjacent side)

tan(θ) = sin(θ)/cos(θ)

cot(θ) = 1/tan(θ)

sec(θ) = 1/cos(θ)

csc(θ) = 1/sin(θ)

Length of the hypotenuse side = The length of the terminal side = 2

Therefore; sin(α) = -2/(2) = -1

cos(α) = 0/2 = 0

tan(α) = -1/0 = ∞

cot(α) = 0/(-1) = 0

sec(α) = 1/0 = ∞

The required probability is 3 √7 / 32.

Given, a square with sides of length 4 units and a red-shaded triangle with sides 3 units, 3 units and 4 units. We need to find the probability that a randomly selected point within the square falls in the red-shaded triangle.To find the probability, we need to divide the area of the red-shaded triangle by the area of the square. So, Area of square = 4 × 4 = 16 square units. Area of triangle = 1/2 × base × height.

Using Pythagorean theorem, the height of the triangle is found as: h = √(4² − 3²) = √7

The area of the triangle is: A = 1/2 × base × height= 1/2 × 3 × √7= 3/2 √7 square units. So, the probability that a randomly selected point within the square falls in the red-shaded triangle is:  P = Area of triangle/Area of square= (3/2 √7) / 16= 3 √7 / 32.
