The equation for number of miles is 14/7 = x and she ran 2 miles each day.

Simplify the equation to bring all the variable terms to one side and the constant value to the other in order to solve linear equations with a single variable. Find the LCM (least common multiple) if there are any fractional terms, then simplify them so that the variable values are on one line and the steady terms are on the other.

Let us suppose the number of miles she ran each day = x.

Given that, Aroline ran 14 miles in 7 days.

Thus,

Total distance / Number of days = x

14/7 = x

x = 2

Hence, the equation is 14/7 = x and she ran 2 miles each day.

The probability that a randomly selected driver in the 20-24 age bracket will be in a car crash during the next year is 0.86%.

It is unlikely for a driver in that age bracket to be involved in a car crash during a year

The resulting probability of 0.0086 is relatively low.

The approximate probability can be calculated by dividing the number of drivers who were in a car crash in the last year by the total number of drivers in the 20-24 age bracket:

Probability = Number of drivers in a car crash / Total number of drivers in the age bracket

Probability = 3/350

Probability ≈ 0.0086

Part 2

Since the probability is less than 0.05, it is unlikely for a driver in that age bracket to be involved in a car crash during a year.

Part 3

While any car accident can be a concern, the resulting probability of 0.0086 is relatively low.

Build the distribution table

of frequencies and histogram of the height (in cm) of 80 third-secondary students.

(Construir la tabla de distribución

de frecuencias e histograma de la altura (en cm) de 80 estudiantes de tercero medio.)

I think this is what you sayed?

For the following:

a) To determine the range of the heights, find the difference between the highest and lowest values.

Range = Highest value - Lowest value

The highest value is 188 cm, and the lowest value is 162 cm.

Range = 188 - 162 = 26 cm

b) The amplitude is the interval width of each class in the frequency table. To determine the amplitude, Know the number of classes. Assume to create 10 classes for the height data.

Amplitude = Range / Number of classes

Amplitude = 26 cm / 10 = 2.6 cm

c) To build the frequency table, to create the class intervals for the height data. Since the amplitude is 2.6 cm, choose the class intervals accordingly.

Set up the frequency table with 10 classes:

Class Intervals: (160 - 162.6], (162.6 - 165.2], (165.2 - 167.8], ..., (185 - 187.6], (187.6 - 190]

Next, count the number of data points falling into each class interval and calculate the absolute frequency (frequency), cumulative frequency, relative frequency, and percentage relative frequency.

The frequency table for the height data is attached.

In the frequency table, the "Cumulative Frequency" column shows the running total of frequencies, the "Relative Frequency" column shows the proportion of each class frequency to the total number of data points (80), and the "Percentage Relative Frequency" column shows the relative frequency expressed as a percentage.

Answer:

20% of the number is 44.0.

Step-by-step explanation:

Let's say the number is "x".

We can start by setting up two equations based on the given information:

0.55x = 121

0.75x = 165

We can solve for x by dividing both sides of each equation by the coefficient of x:

x = 121/0.55 ≈ 220.0

x = 165/0.75 = 220.0

Now that we know the value of x, we can find 20% of it by multiplying it by 0.20:

0.20 * 220.0 = 44.0

Therefore, 20% of the number is 44.0.

Answer: If Colleen selected one egg, cracked it open and found out it was raw, the probability of selecting the hard-boiled egg on her second pick is 1/5, and the probability of Colleen selecting the hard-boiled egg on her first try is 1/6.

To see why, let's consider the possible scenarios:

Colleen selects the hard-boiled egg on her first try. There is only 1 hard-boiled egg out of the 6, so the probability of this happening is 1/6.

Colleen selects a raw egg on her first try. There are 5 raw eggs out of the 6, so the probability of this happening is 5/6. After she cracks open the raw egg, there will be 4 raw eggs and 1 hard-boiled egg left. So the probability of selecting the hard-boiled egg on her second pick is 1/5.

Therefore, the statement "If Colleen selected one egg, cracked it open and found out it was raw, the probability of selecting the hard-boiled egg on her second pick is 1/5, and the probability of Colleen selecting the hard-boiled egg on her first try is 1/6" is true.

The figure has rotational symmetry of order 2 and to achieve rotational symmetry of order 4, three plates need to added.

Explain about symmetry?

Symmetry is a property of an object that describes how it appears identical after some transformation, such as reflection, rotation, or translation. It is an essential concept in mathematics, science, art, and many other fields.

There are several types of symmetry, including:

Reflectional symmetry (also called bilateral symmetry).
Rotational symmetry.

Translational symmetry.

According to the question:

a. The figure has rotational symmetry of order 2. This means that if we rotate the figure 180 degrees around its center, the figure will look exactly the same as it did before the rotation.

b. To achieve rotational symmetry of order 4, we need to add plates in such a way that the figure looks the same after a rotation of 90 degrees, 180 degrees, and 270 degrees around its center.
To achieve this, we can add three more plates to the figure, one in between each pair of existing plates, After adding these plates, the figure has rotational symmetry of order 4. We can see this by rotating the figure 90 degrees, 180 degrees, and 270 degrees around its center

so the figure has rotational symmetry of order 4. Therefore, we only needed to add three plates to the figure to achieve rotational symmetry of order 4 around its center.

The equation of the line that represents the total cost is c = 4d + 8 and the total cost when 1 drink is bought is $ 12.

The slope-intercept form of a line has used to form a linear equation in two variables. It is called the slope-intercept form because it gives us two pieces of information about the line its slope and y-intercept.

The slope-intercept form of a line is given by the equation:

where:

m is the slope of the line

b is the y-intercept of the line

Here we have

The graph shows the total cost c of buying one large bucket of popcorn and d large drinks.  

From the graph, the line passes through points (0, 8) and (1, 12)  

Hence, slope of the line (m) = [(y₂ - y₁) / (x₂ - x₁) ]

= [(12 - 8) / (1 - 0) ] = [4 / 1] = 4

Let y = mx + c be the lines

=> y = 4x + c

Since the line passes through (0, 8)

=> 8 = 4(0) + c

=> c = 8

Hence, the required equation is y = 4x + 8  

From the data,

The y-axis represents the total cost 'c' and the x-axis represents the number of drinks 'd'

=>  Total cost c = 4d + 8

Hence,

The equation of the line that represents the total cost is c = 4d + 8

If we bought 1 large drink

=> c = 4(1) + 8 = 12

Therefore,

The equation of the line that represents the total cost is c = 4d + 8 and the total cost when 1 drink is bought is $ 12.

Answer:

The given equation is of the form:

((x - h)^2)/a^2 - ((y - k)^2)/b^2 = 1

Comparing it with the given equation:

((x - 3)^2)/10 - ((y + 5)^2)/9 = 4

We can rewrite the equation in the standard form by dividing both sides by 4, then adding (y+5)^2/9 to both sides:

((x - 3)^2)/40 - ((y + 5)^2)/36 = 1

Now, we can see that the equation is in the standard form of a hyperbola. The center of the hyperbola is (3, -5), the distance between the center and each vertex is sqrt(10) in the x-direction and sqrt(9) in the y-direction, and the hyperbola opens to the left and right.

Step-by-step explanation:

First, we need to perform the multiplication operation within the parentheses, following the order of operations:

2⅓ × 1¼ = (7/3) × (5/4) = 35/12

Now, we can substitute the values in the expression:

3½ - (2⅓ × 1¼) + ⅗ = 7/2 - 35/12 + 3/5

To add or subtract fractions with different denominators, we need to find a common denominator. The least common multiple of 2, 12, and 5 is 60, so we can rewrite the fractions with this denominator:

7/2 - 35/12 + 3/5 = (210/60) / (2/2) - (175/60) / (12/12) + (36/60) / (5/5)

Simplifying the fractions within the parentheses:

= 210/60 - 175/60 + 36/60

= 71/60

Therefore, 3½ - (2⅓ × 1¼) + ⅗ simplifies to 71/60.

Therefore, if a population of 150 mice triples in size every four months, there will be approximately 2,952,450 mice in the neighbourhood in 3 years.

Mathematicians use the unitary method to answer proportional relationship problems involving two or more quantities. It entails calculating the worth of one unit of one quantity in relation to another. For instance, let's say we are aware that 3 pencils cost $6. The following is how we can calculate the price of a solitary pen using the unitary method: The value of a single entity of the quantity "pen cost" in terms of the quantity "number of pens" was determined in this case. Once we are aware of a unit's worth, we can use that knowledge to determine the value of any other quantity that is related to it.

given

The population triples, or grows three times, in number, after four months. As a result, if we commence with 150 mice, the population will look like this after 4 months:

150 × 3 = 450 mice

The populace will triple once more after another 4 months (or 8 months from the beginning), becoming:

450 × 3 = 1350 mice

The populace will triple once more after another 4 months (or 12 months from the beginning), becoming:

1350 × 3 = 4050 mice

There is a pattern here: every four months, the populace triples. Therefore, we can determine how many times the population triples after three years (or 36 months) have passed:

36 months divided by 4 months per triple equals 9 triples.

the following group will exist after three years:

2,952,450 mice are equal to 150 × 39 (150 x 19,683).

In compensation for products or services received or to fulfill a legal duty, payment is the voluntarily given exchange of money, its equivalent, or other valuables from one person to another. Frequently, the individual giving the money is referred to as the payer, while the person receiving it is referred to as the payee.

Assuming that the payments are made at the end of each month, we can use the formula -

[tex]A = PMT\Bigg[\frac{\big(1+\frac{APR}{n}\big)^{nY}-1}{\frac{APR}{n}}\Bigg][/tex]

where -

A = the savings plan balance after 2 years

PMT = the monthly payment ($150)

APR = the annual percentage rate (6%)

n = the number of compounding periods per year (12, since the payments are made monthly)

Y = the number of years (2)

Plugging in the values, we get -

[tex]A = 150\Bigg[\frac{\big(1+\frac{0.06}{12}\big)^{12 \times 2}-1}{\frac{0.06}{12}}\Bigg][/tex]
