The probability that a driver chosen at random from the community will be in the low-risk category for the next year is 0.8

Probability:

In math,  the ratio of the times an event is likely to occur divided by the total possible events is known as probability.

Given,

Here we need to find if 80% of the drivers in the community are in the low-risk category this year, then the probability that a driver chosen at random from the community will be in the low-risk category for the next year.

Here we know that, 80% of the drivers in the community are in the low-risk category this year.

The number line of the set C ={x : x ≤ -3} is attached

From the question, we have the following parameters that can be used in our computation:

Set C ={x:x<=-3}

Rewrite properly

So, we have

Set C ={x : x ≤ -3}

Remove the curly braces from the set notation

So, we have the following representation

x ≤ -3

There are no multiples and factors to divide or multiply

Also, there are no terms to subtract or add

Answer:

Step-by-step explanation:

1.24 × 4 = 5

or it can be 1.24 ÷2 =0.265

Step-by-step explanation:

The spherical and Cartesian coordinates are related by the equations,

x = ρ sin(φ) cos(θ)

y = ρ sin(φ) sin(θ)

z = ρ cos(φ)

Here, x, y and z represent the coordinates of the center of the sphere on x, y and z axes respectively.

Now, multiply the given surface equation by ρ.

ρ² = ρsin(θ) sin(φ)

We have, ρ² = x² + y² + z².

Substitute this value in above equation and also replace the RHS by y coordinate.

x² + y² + z² = y

Now, simplify the above equation.

x² + y² - y + z² = 0

x² + y² - 2y½ + (1/2)² + z² = (1/2)²

x² + (y - 1/2)² + z² = (1/2)² ...(1)

The general form of equation of sphere is,

(x - a)² + (y - b)² + (z - c)² = r²

Here, a, b, c are the coordinates of the center of the sphere on x, y, z axes respectively and r is the radius of the sphere.

Compare equation (1) with the general form of equation of sphere. Therefore we get,

Therefore, the radius of the sphere is 1/2 and center of sphere is at (0, 1/2, 0).

Thus, The given equation represents - a sphere of radius 1/2 centers at (0, 1/2, 0).

By using some exponent properties, we will find the equivalent expression:

(m⁻²*n⁻³)⁻⁴ = m⁸*n¹²

Here are some exponent properties that we need to use:

(aⁿ)ˣ = aⁿ*ˣ

(a⁻ⁿ) = (1/a)ⁿ

Here we have the expression:

(m⁻²*n⁻³)⁻⁴

The exponents can be distributed under multiplication, then:

(m⁻²)⁻⁴*(n⁻³)⁻⁴

Now we can use the first property so we get:

(m⁻²)⁻⁴*(n⁻³)⁻⁴ = m⁽⁻²*⁻⁴⁾*n⁽⁻³*⁻⁴⁾

m⁽⁻²*⁻⁴⁾*n⁽⁻³*⁻⁴⁾ = m⁸*n¹²

That is the equivalent expression.

The probability that the person selected will be someone whose response is never and who is a woman is 0.0636 = 6.36%.

A probability of an occurrence in the context of a problem is calculated by dividing the desired outcomes in the problem by the entire number of outcomes in the problem.

In the context of this problem, these outcomes are given as follows:

Desired outcomes: people whose response is never and who are women.

Total outcomes: all participants.

Hence, as all participants represent the desired outcomes, the probability that the person selected will be someone whose response is never and who is a woman is the relative frequency of people who are women and who respond never, which is: 0.0636 = 6.36%.

Answer:

7a + 9b

Step-by-step explanation:

"a" is basically a shorter way of writing "1a;" and this is the same way for any singular variable. Examples would variables like "a," "b," "c," and so on. So the real equation would be 6a + 1a + 8b + 1b. If 2 numbers have the same variable then you can add them together. You solve it like this:

6a + 1a = 7a

8b + 1b = 9b

The equivalent of 6a +a + 8b + b is 7a + 9b.

Find:  [tex]\textsf{The average daily balance of Elliott's account for the month of June}[/tex]

Solution: In order to get the average daily balance, we need to use a formula where we have a weighted balance for each day.  For example, out of the 30 days in June, 9 of the days there was $1223 in the account, for 5 days there was $1223 + $615 in the account, for 7 days there was $1223 + $615 - $63 in the account, and for the last 9 days there was $1223 + $615 - $63 - $120 in the account.  This all happened over 30 days and to translate this to an equation it will look something like the following.

Convert to equation and simplify

Therefore, the final answer would be that the average daily balance of Elliott's account for the month of June would be $1583.9 per day.

In contrast to the fact that almost all time series contain a random component, certain time series do not.

A TIME SERIES IS WHAT?

A time series is a group of observations of clearly defined data points produced over time via repeated measurements. A time series would include, for instance, calculating the amount of retail sales for each month of the year. This is due to the well defined and regular measurement of sales income at uniformly spaced intervals. Time series data are not those that are irregularly or once collected.

Three parts can be separated out of a time series observation: the trend (long-term direction), the seasonal (systematic, calendar-related motions), and the irregular (unsystematic, short term fluctuations).

In mathematics, a time series is a collection of data points that have been indexed chronologically.

A time series is typically a sequence that was recorded at a number of evenly spaced points in time.

It is therefore a set of discrete-time data.

g(x) = x^2 - 3

f(x) = x^3+7x^2-x

Start with the g(x) function. Replace every x with f(x)

g(x) = x^2 - 3

g(f(x)) = ( f(x) )^2 - 3

Then replace the f(x) on the right side with x^3+7x^2-x

g(f(x)) = (x^3+7x^2-x)^2 - 3

The highest term inside the parenthesis is x^3. Squaring this leads to (x^3)^2 = x^(3*2) = x^6

So the highest exponent found in g(f(x)) is 6, meaning the degree of is 6

Answer:

A linear function is a function whose graph is a straight line. An exponential function is a function in which the variable appears in an exponent. A linear function has a constant rate of change, meaning that the rate of change between two points on the line is the same. An exponential function has a variable rate of change, meaning that the rate of change between two points on the line is not constant.

Explanation: A linear function, has y-values with equal differences. An exponential function has y-values with equal ratios.

Using the frequency table, the number of values greater than or equal to 7 is 36.

Frequency refers to the number of times an event or a value occurs.

A frequency table is a table that lists objects and shows the number of times the items occur.

The distribution of observations based on a variable's possible values is displayed in a frequency table.

Frequency tables are helpful to determine which alternatives appear more or less often in the dataset.

This is useful for better understanding each variable and determining whether or not variables need to be recorded.

So, values greater than or equal to 7:

Refer to the frequency table attached below.

The value of 7 is 3.

Sum of all values that is equal to 3 or greater than 3 as follows:
