Determine whether the ratios are proportional.
10/12 , 15/18

Answer:

50%

Step-by-step explanation:

The distribution is symmetrical about  the y-axis.

The probability that z is greater than zero in a standard normal distribution is 0.5 or 50%.

The branch which deals with the occurrence of a random event is known as probability.

The area under the curve to the right of z = 0 is equal to the area under the curve to the left of z = 0. So the standard normal distribution is symmetric about the mean of zero

As the total area under the curve is equal to 1, each of these areas must be 0.5 or 50%.

In a standard normal distribution, the probability that z is greater than zero is 0.5, or 50%.

Therefore, the probability that z is greater than zero in a standard normal distribution is 0.5 or 50%.

Answer:

Total length of string required in yards \(8112\) yards

Step-by-step explanation:

The length of the string attached with each balloon is equal to \(12\) feet

In the party total number of balloon used is equal to \(52\) balloons

The total length of the string required

Length of string used in one balloon * total number of balloons

\(= 12 * 52 = 624\) feet

1 feet is equal to 13 yards

Rolling a total of 8 when two dice are rolled is more likely than rolling a total of 8 when three dice are rolled.

This is because there are more combinations of two dice that can add up to 8 (four combinations; 1-7, 2-6, 3-5, 4-4) than there are combinations of three dice (three combinations; 1-3-4, 2-2-4, 3-3-2).

Therefore, the probability of rolling a total of 8 with two dice is greater than the probability of rolling a total of 8 with three dice.

Additionally, the odds of rolling a total of 8 with two dice can be calculated using the formula (Number of favourable outcomes/Total number of outcomes) x 100%.

In this case, the formula would be (4/36) x 100%, which equals 11.11%. The odds of rolling a total of 8 with three dice is calculated using the same formula, which would be (3/216) x 100%, which equals 1.39%.

This shows that the odds of rolling a total of 8 with two dice is much greater than the odds of rolling a total of 8 with three dice.

The limit of f(x)g(x) as x approaches 6 can exist even if it is not equal to f(6)g(6).

Determine whether the statement is true or false. If it's accurate, describe why. If it's untrue, explain why or provide an illustration that refutes it.

If limx → 6 [f(x)g(x)]

exists, then the limit must be f(6)g(6).

This statement is false. One can create a counter-example by doing the following:

Let f(x) = x - 6 and g(x) = 1/(x - 6). Then f(6) = 0 and g(6) is undefined. However, the limit of f(x)g(x) as x approaches 6 exists and is equal to 1, since the function f(x)g(x) simplifies to 1 for all x ≠ 6.

Even if it is not equal to f(6)g(6), the limit of f(x)g(x) as x approaches 6 can still exist (6).

\(p\geq 1.15(4,500)\)

The price of the car is multiplied by 1.15, because she must add her profit comission which is 0.15 or 15%.

The rate of change for the equation y - x = 10 is 1.

To find the rate of change for the equation y - x = 10, we need to determine how y changes with respect to x.

We can rewrite the equation as y = x + 10 by adding x to both sides.

Now, we can observe that the coefficient of x is 1. This means that for every unit increase in x, y will increase by 1. Therefore, the rate of change for this equation is 1.

In other words, as x increases by 1 unit, y will increase by 1 unit as well.

As a result, 1 represents the rate of change for the equation y - x = 10.

The estimated crop yield from the simulation is 443 (option b).

To estimate the crop yield from the given random numbers, we need to assign a specific meaning to each random number. Let's assume that each random number represents the crop yield for a particular year.

Given random numbers: 37, 23, 92, 01, 69, 50, 72, 12, 46, 81

To find the estimated crop yield, we sum up all the random numbers:

37 + 23 + 92 + 01 + 69 + 50 + 72 + 12 + 46 + 81 = 443

Two years from now, there will be a total of 36 lakh (3.6 million) students using Khan Academy in India.

If 16 lakh students in India are currently using Khan Academy, and the number of users is expected to grow by 50% every year, then the number of users two years from now can be calculated as follows:
- After one year: 16 lakh x 1.5 = 24 lakh
- After two years: 24 lakh x 1.5 = 36 lakh
Therefore, two years from now, it is expected that 36 lakh students in India will be using Khan Academy.
To calculate the number of students using Khan Academy in India two years from now, we'll use the given growth rate of 50% per year.
Currently, there are 16 lakh (1.6 million) students using Khan Academy. After the first year, the number of users will grow by 50%, which is an increase of 8 lakh (0.8 million) students. This will bring the total to 24 lakh (2.4 million) students.
After the second year, the number of users will again grow by 50%. This time, the increase will be 12 lakh (1.2 million) students. So, two years from now, there will be a total of 36 lakh (3.6 million) students using Khan Academy in India.

The coefficient of determination, R2, is a measure of how much of the variation in the data is explained by the regression model. It ranges from 0 to 1, with higher values indicating better model fit.

The coefficient of determination, R2, is a measure used to evaluate how well a regression model fits the data. It is a number between 0 and 1, with higher values indicating a better fit. A perfect fit will have an R2 value of 1, while a value of 0 indicates that the model does not explain any of the variation in the data. R2 is calculated as the ratio of the variance explained by the model to the total variance in the data. This measure is often used to compare different models and select the best one for a given data set. It is also used to assess how well a given model fits the data, as a way of determining the accuracy of the model's predictions.

Answer:

Step-by-step explanation:

The parenthesis can cancel because the lack of anything you can do in them, so that will leave you with 7m + 3 + 7m + 6

Next step is to add like numbers, you should start by adding 7m + 7m, which would be 14m.

Next would be to add 3 + 6, which is nine.

To end this equation, simply put 14m + 9

There is no one-number answer because we do not know what m is. So the equation 14m + 9 is the final answer.

There are 50 customers per week.

Since average can be calculated by dividing the sum of observations by the number of observations.

Average = Sum of observations/the number of observations

We are given that During the month of May she averaged 47 customers the first week, 38 the second week, 55 the third week, and 60 the fourth

week.

therefore, consider that w represent the number of customers in the 1st week, x represent the number of customers in the 2nd week, y represent the number of customers in the 3rd week and z represent the number of customers in the 4th week.

Then the average would be;

w + x + y + z= 4A

47 + 38 + 55 + 60 = 4A

The value of the equation x² - x + 3 is 37/9.

We have,

We can start by multiplying both sides of the equation by x:

2x - 3/x = x + 1

2x - 3 = x^2 + x

Rearranging and simplifying, we get:

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

x^2 - x + 3 = x^2 + 2x - 3

-x + 3 = 2x - 3

5 = 3x

x = 5/3

Now we can substitute x into the equation x^2 - x + 3:

x^2 - x + 3 = (5/3)^2 - 5/3 + 3

x^2 - x + 3 = 25/9 - 15/9 + 27/9

x^2 - x + 3 = 37/9

Therefore,

The value of x² - x + 3 is 37/9.
