The lines a and b are parallel. The proof is given.
What is congruent?In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.
Given:
Statement 1:
∠1 and ∠6 are supplementary.
Justification:
If two angles sum up to 180 degrees, they are referred to as supplementary angles.
That means,
∠1 + ∠6 = 180°
∠1 = 180°- ∠6
∠1 =∠5, given that the angles are made by intersecting lines.
Statement 2:
∠1 ≅∠4
Justification:
Vertical angles are also congruent angles, meaning they are equal or have the same measurement.
Two crossing lines actually create two sets of opposite angles that, when the measures of their angles, are added all together.
Since, ∠1 ≅∠4
That means, ∠4 and ∠6 are supplementary.
Statement 3:
∠4 and ∠6 are supplementary.
Justification:
If two angles sum up to 180 degrees, they are referred to as supplementary angles.
Statement 4:
a and b are parallel lines.
Justification:
This means that lines a and b make the same angle with the intersecting line, meaning they don't intersect each other at any point.
a and b are parallel lines.
Therefore, the all statements are true.

You are given the difference of the numbers of boys and girls in a class and the ratio of boys to girls. How many boys and girls are in class?
3 more boys; 5 for every 4
Answers
Answer:
By using the given ratio, we will see that there are 15 boys and 12 girls.
How we can find the number of boys and girls in the class?
The given information is:
There are 3 more boys.
There are 5 boys for every 4 girls.
Now, notice that in the ratio we have a difference of 1 boy, so if we want to have a difference of 3 boys, we must multiplicate it by 3, then we get:
3*15 boys for every 3*4 girls (remember that you can multiply both quantities on the ratio and it does not change).
15 boys for every 12 girls.
Now the difference is 3.
15 - 12 = 3
So we can conclude that there are 15 boys and 12 girls.

Answer:x=-3
Step-by-step explanation:
if you were to plug in -3 for f(x) you would get, f(-3)=1/3(-3) +2, which then equals f(-3)=-1+2, so f(-3)=1
Now you do the same thing for g(x), so you would get g(-3)=2^(-3+3), meaning you first add -3 and 3 leaving you with g(-3)=2^0, which is equal to 1.
f(-3)=1=g(-3)

Answers
She'll need 4 gallons of 15% ethanol gasoline and 5 gallons of 78% ethanol gasoline.
What is expression?An expression or mathematical expression is a finite collection of symbols that is well-formed according to context-dependent norms.
Here,
The number of gallons required of both kind would be as follows:
4 gallons having 15% ethanol
5 gallons having 78% ethanol
Given that,
The 2 kinds of gases are:
One with 15% ethanol
Other with 78% ethanol
Given that,
The gases(ethanol and gasoline) are diluted in a such a manner that it involves a total of only 50% ethanol.
Number of gallons she wants to use = 9
This shows that only 50% of 9 gallons i.e. 4.5 gallons of ethanol can be used.
Assuming x being the gasoline's measure that is diluted with 15% ethanol.
Now,
The gasoline's measure that is diluted with 78% ethanol would be = 9 - x gallons
Therefore,
x × 15% + (9-x) × 78% = 4.5
On solving, we get
x = 4 gallons
Thus,
The measure of gallons having 15% ethanol = 4
The measure of gallons having 78% ethanol = (9 - x)
= (9 - 4)
= 5 gallons
She will use 4 gallon of 15% ethanol gas and 5 gallon of 78% ethanol gas.

Step-by-step explanation:
To find the midpoint, we must average the x coordinates to find the x-coordinate of the midpoint and average the y-coordinates to find the y-coordinate of the midpoint.
Thus, we do:
x-coordinate: [tex]\frac{2 + 8}{2}[/tex] = [tex]\frac{10}{2}[/tex] = [tex]5[/tex]
y-coordinate: [tex]\frac{-5 + 3}{2}[/tex] = [tex]\frac{-2}{2}[/tex] = [tex]-1[/tex]

what formula is used to gain information about an individual data value when the variable is normally distributed?
Answers
The formula used to gain information about an individual data value when the variable is normally distributed is called the z-score formula.
It is used to calculate how many standard deviations a value lies above or below the mean of the data set. The formula is:
z-score = (x - μ) / σ
where x is the data value, μ is the mean of the data set, and σ is the standard deviation of the data set.
To find the z-score of an individual data value when the variable is normally distributed, use the z-score formula. This formula subtracts the mean (μ) from the data value (x) and divides by the standard deviation (σ). This calculation will give you the number of standard deviations the data value lies above or below the mean.

What is normal distribution?
A continuous probability distribution for a real-valued random variable is called a normal distribution or a Gaussian distribution in statistics.
The normal distribution describes a symmetrical plot of data around its mean value, with the standard deviation serving as the determinant of the curve's width. The "bell curve" is used to visually represent it.
Given:
Lengths of pregnancies of women are normally distributed with a mean of 266 days and a standard deviation of 16 days.
⇒ μ = 266, σ = 16
Consider, the normal distribution formula
f(x) = (1 / σ√2π) e^(-1/2)(x - μ/ σ)^2
For x = 274,
f(274) = (1 / 16√2π) e^(-1/2)(274 - 266/16)^2
f(274) = 0.02
Hence, the percentage of children are born from pregnancies lasting less than 274 days are 0.02.
For x = 246
f(246) = (1/16√2π) e^(-1/2)(246 - 266/16)^2

Answers
The mean of the numbers 5, 2x, 4 and 3 is 5. Find the value of x.
Answers
Answer:
(5 + 2x + 4 + 3)/4 = 5
(12 + 2x)/4 = 5
3 + 1/2x = 5 (multiply by 2
6 + x = 10
x = 4
The numbers are 5, 8, 4 and 3.

heart and star pls <3 brainliest will be appreciated <3(っ◔◡◔)っ -{ elyna s }-how do you ensure accurate predictions using data correlation? which are the most effective methods?
Answers
The only kind of data generated by observational research is correlations or patterns in the data that have been observed. By using correlations, one variable's value can be used to predict the value of another.
Explanation:
Accurate predictions using data correlation can be ensured by using a variety of methods. Firstly, it is important to ensure that the data is free from errors and is of high quality. This can be done by cleaning and validating the data to remove any inconsistencies and outliers. Secondly, it is important to analyze the data thoroughly and identify any patterns or trends. Furthermore, it is beneficial to use appropriate statistical tests and algorithms such as linear regression, logistic regression, and decision trees to identify the predictive relationships between the variables. Finally, it is important to evaluate the model’s performance to determine the accuracy of the predictions.
The most effective methods for ensuring accurate predictions using data correlation are:
1. Perform Exploratory Data Analysis: Exploratory data analysis is an essential step in any predictive modeling process. It involves exploring the data to identify patterns, trends, and relationships within the data. This helps to identify any potential issues or biases within the data that could affect the accuracy of predictions.
2. Use Statistical Tests: Statistical tests can be used to measure the strength of the relationship between two variables. These tests can help to identify which variables are most strongly correlated with each other and can help to determine which variables should be used in a predictive model.
3. Use Machine Learning Algorithms: Machine learning algorithms can be used to create predictive models that can identify and learn patterns in the data. These algorithms are particularly effective at identifying complex relationships between variables that may not be identified by statistical tests.
4. Validate Predictions: Predictions should always be validated to ensure that they are accurate and reliable. This can be done by comparing the predictions against known outcomes or by testing the model on a separate data set.

the ages for a random sample of 30 employees at house mart resulted in the following descriptive statistics. the lower and upper limits for a 99% confidence interval would be approximately and ?
Answers
The lower and the upper limit for a 99% confidence interval would be approximately 37.51 and 50.03
Here,
Mean = 43.77
Standard deviation (s)= 12.43655
n= 30
So,
CI= mean ± t (s/√n)
= 43.77±2.756(12.43655/√30)
= 43.77±6.26
= 37.51,50.03
So, the lower and upper limit would be 37.51 and 50.03
