Given that 5% of people with blood type o are left-handed, the likelihood that this person has blood type o is 9/44.

A branch of mathematics called probability theory determines the likelihood that an event will occur or that a statement is true. A probability is a number between 0 and 1, where 1 denotes certainty and about 0 denotes how probable an event is to occur. The possibility or likelihood that a specific event will occur is expressed numerically as a probability. Probabilities can also be expressed as percentages from 0% to 100% or as numbers between 0 and 1. the proportion of occurrences among all equally likely alternatives that lead to a certain occurrence relative to all possible outcomes.

given

E2 =Event that the person selected is of other than blood group O

(E3)=Event that selected person is left handed

∴P(E1)=0.30,P(E2)=0.70

P(E3/E1)=0.06andP(E3/E2)=0.10

By using Baye's theorem, P(E1/E3)=P(E1)⋅P(E3/E1)P(E1)⋅P(E3/E1)+P(E2)⋅P(E3/E2)

=0.30×0.06 /0.30⋅0.06+0.70⋅0.10

=0.0180/0.0180+0.0700

=0.0180/0.0880=180 /880=9 /44

Given that 5% of people with blood type o are left-handed, the likelihood that this person has blood type o is 9/44.

If x = 5 dollars and Aisha has x (5 dollars) more than Tomas, then that means 10 + 5 = 15.

Answer:

aisha has 15 dollars

Step-by-step explanation:

the word more indicates that you are adding. since tomas has 10 and aisha has x (and x = 5) more (+), you are adding 5 to what tomas has.

10 + 5 = 15

The answer to the problem is 1843.

To solve the equation ? − 1529 = 314,

Let the unknown be x

we need to isolate the variable on one side of the equation.

Adding 1529 to both sides, we get:

x − 1529 + 1529 = 314 + 1529

Simplifying, we get:

x = 1843

Answer:

\(2 \div \frac{8}{9} = 2 \times \frac{9}{8} = \frac{9}{4} = 2.25\)

I hope I helped you^_^

Answer:

Step-by-step explanation:

Use KCF method for fraction division.

K- Keep the first fraction.

Change the division to multiplication.

Flip the second fraction

2 ÷ 8/9 = \(2 * \dfrac{9}{8}\)

             \(= 1*\dfrac{9}{4}=\dfrac{9}{4}\\\\= 2\dfrac{1}{4}\)

By dividing the output power (work completed) by the input power ratio, the motor's efficiency may be determined. In this instance, the input power is 300 W, and the output power is 2400 joules (400 N * 6.0 m). As a result, the motor has an efficiency of 2400 J/300 W, or 8.0.

The input power is 300 W.

Time (t) = 20 s

Height is 6.0 metres.

(F) = 400 N Load

Output power (Pout) is calculated as follows: F x h = 400 N x 6.0 m = 2400 J

Efficiency (e) is calculated as Pout / P = 2400 J / 300 W = 8.0.

A motor's efficiency can be determined by dividing its output power by its input power. Assuming that the input power is 300 W and the output power equals the amount of work completed, the load (F) and height can be multiplied to determine the output power (h). The output power in this example is 2400 joules (400 N * 6.0 m) since the load is 400 N and the height is 6.0 m. The motor's efficiency is 2400 J/300 W, or 8.0, as a result. Knowing the input power, output power, and length of time it took the motor to lift the load will help you determine the efficiency. In this illustration, the time is 20 s, and the input power is 300 W.

Simple linear regression is a statistical technique used to model the relationship between two variables by fitting a straight line to the data. It provides a way to predict or estimate the value of one variable (dependent variable) based on the value of another variable (independent variable).

In simple linear regression, the relationship between the independent variable (x) and the dependent variable (y) is represented by a straight line. The goal is to find the best-fitting line that minimizes the differences between the observed values of the dependent variable and the predicted values from the regression line.

A graph illustrating simple linear regression includes the scatterplot of the data points, the regression line, and the residuals. The scatterplot shows the individual data points with the independent variable on the x-axis and the dependent variable on the y-axis. The regression line is the line that best fits the data, minimizing the sum of the squared residuals.

Residuals are the vertical distances between the observed data points and the regression line. They represent the differences or errors between the actual values and the predicted values. By examining the residuals, we can assess how well the regression line fits the data. If the residuals are randomly scattered around zero, it suggests that the linear regression model is appropriate. If there is a pattern or systematic deviation in the residuals, it indicates that the model may not be capturing the underlying relationship accurately.

The regression line is constructed by minimizing the sum of the squared residuals, which is known as the least squares method. This ensures that the line represents the best linear approximation of the relationship between the variables.

Answer: D

Explanation:

The expression we have is:

First we use the distributive property to multiply the "-" by the second parenthesis, also we can ignore the parenthesis on the first term:

This is because "-" by 3x^2 is equal to -3x^2. And "-" by -7x is equal to +7x, and "-" by +4 is equal to -4.

Next, we combine like terms (terms that have the same variable are like terms, also independent terms without variable are like terms):

This is because -5x+7x =2x, and +4-4=0 so they are eliminated.

To present this in standard form we leave the term with the bigger exponent at the beginning of the expression:

Which is option D.

Malena's steps arranged sequentially are :

The first step :

2x + 5 = -10 - x

collecting like terms

2x + x = -10 - 5

step 2 : Using the appropriate numerical operator:

3x = -15

step 3 : divide both sides by 3 to isolate x

The statements that are true for this parabola are:

C. The point (8, 6) is the same distance from the point (4, 3) as it is from the line y = 1.

Option D.

Given the following data:

Mathematically, the standard equation of the directrix line for a parabola is given by: y = a(x - h)² + 2.

Next, we would determine the distance where point (8, 6) lie on the parabola as follows:

y = a(x - h)² + 2

6 = a(8 - 4)² + 2

6 = a(4)² + 2

6 = 16a + 2

16a = 6 - 2

16a = 4

a = 4/16

a = 1/4.

Therefore, the parabolic equation becomes:

y = 1/4(x - 4)² + 2

When x = 2, we have:

y = 1/4(2 - 4)² + 2

y = 1/4(-2)² + 2

y = 1/4(4) + 2

y = 1 + 2

y = 3.

Step-by-step explanation:

\( = > 3 - 7c - 20c = 7( - 7c - 19) + 14c \\ \\ = > 3 - 27c = ( - 7c \times 7) - (7 \times 19) + 14c \\ \\ = > 3 - 27c = - 49c - 133 + 14c \\ \\ = > 3 - 27c = - 35c - 133 \\ \\ = > 3 - 27c + 35c = - 133 \\ \\ = > 3 + 8c = - 133 \\ \\ = > 8c = - 133 - 3 \\ \\ = > 8c = - 136 \\ \\ = > c = - \frac{136}{8} \\ \\ = > c = - 17\)

Answer:

c = -17

Step-by-step explanation:

→Distribute the 7 to (-7c - 19):

3 - 7c - 20c = -49c - 133 + 14c

→Add like terms (-7c and -20c, -49c and 14c):

3 - 27c = -35c - 133

→Add 35c to both sides:

3 + 8c = -133

→Subtract 3 from both sides:

8c = -136

→Divide both sides by 8:

c = -17

The estimated error rate per field in the compliance audit is calculated, along with its standard error. The total number of errors in the population is also estimated. If an SRS of 18,275 fields had been taken instead of a cluster sample, the estimated variance for the error rate would be different.

To estimate the error rate per field (a), we calculate the total number of errors (sum of errors in each claim) and divide it by the total number of fields checked in the sample. The average error rate per field is then calculated along with its standard error. To estimate the total number of errors in the 828 claims (b), we multiply the estimated error rate per field by the total number of fields in the population.

If an SRS of 18,275 fields had been taken (c), the estimated error rate per field would be the same as in (a). However, the estimated variance (û) for the error rate would differ. In the original cluster sample, the variance was calculated based on the variation between different claims. In the SRS, the variance would be calculated based on the variation within the fields, assuming each field is an independent unit. Therefore, the estimated variance (û) in the SRS would be lower than the variance in the cluster sample, as the cluster sample accounts for the correlation within claims.
