Answer:
When two parallel lines are intersected by a transversal, the alternate interior angles are the pairs of non-adjacent angles that are located between the two parallel lines and on opposite sides of the transversal. These angles are congruent, which means they have the same measure. The other type of angles mentioned in the statement, which are supplementary, are the pairs of adjacent angles that are located on the same side of the transversal and outside the parallel lines. These angles add up to 180 degrees.
The correct choice is "consecutive interior angles are supplementary."
Find the area of each triangle.
The area of the triangle is 2√2 square units.
This is a right triangle, and the base (the side opposite the right angle) has a length of 2√2.
We can use the Pythagorean theorem to find the length of the other two sides:
x² + x² = (2√2)²
2x² = 8
x² = 4
x = 2
So the two other sides have a length of 2.
Now we can use the formula for the area of a triangle:
Area = (1/2) × base × height
In this case, the base is 2√2 and the height is 2, so we have:
Area = (1/2)×2√2 ×2
Area = 2√2
Therefore, the area of the triangle is 2√2 square units.

What is the Fundamental Counting Theorem?The Fundamental Counting Theorem states that if there are m ways to do one thing and n ways to do another, then there are m x n ways to do both.
This can be extended to more than two events, where the number of ways to do all the events is the product of the number of ways to do each individual event, according to the equation presented as follows:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
The codes are composed as follows:
Two letters -> each with 22 options, as letters can be repeated.Three digits -> each with 8 options, as digits can also be repeated.Thus the total number of codes is obtained as follows:
N = 22² x 8³

A Pew Research Center poll of 1060 teens aged 13 to 17 showed that 57% of them have made
new friends online. Use a 0.01 significance level to test the claim that half of all teens have
made new friends online.
Using a standard normal distribution table or calculator, we can find the p-value associated with z = 4.39 to be less than 0.0001.
For test the claim that half of all teens have made new friends online, we can use a hypothesis test.
Null hypothesis:
The proportion of teens who have made new friends online is equal to 0.5.
Alternative hypothesis:
The proportion of teens who have made new friends online is not equal to 0.5.
We will use a one-sample proportion test with a significance level of 0.01.
For calculate the test statistic, we can use the formula:
z = (p - P₀) / sqrt(P₀ * (1 - P₀) / n)
where p is the sample proportion, P₀ is the hypothesized proportion (0.5), and n is the sample size.
Using the given information, we have:
p = 0.57
P₀ = 0.5
n = 1060
Plugging these values into the formula, we get:
z = (0.57 - 0.5) / sqrt(0.5 x 0.5 / 1060)
z = 4.39
Hence, Using a standard normal distribution table or calculator, we can find the p-value associated with z = 4.39 to be less than 0.0001.
Since the p-value is less than the significance level of 0.01, we reject the null hypothesis and conclude that there is sufficient evidence to suggest that more than half of all teens have made new friends online.

On the 6th grade math test, twelve students had a score of 80 points. Eight students had a score of 88 points.
What was the class average?
The requried class average is 83.2 points.
To find the class average, we need to calculate the total number of points earned by all the students and divide by the total number of students.
The 12 students who scored 80 points earned a total of 12 × 80 = 960 points.
The 8 students who scored 88 points earned a total of 8 × 88 = 704 points.
The total number of points earned by all the students is 960 + 704 = 1664 points.
The total number of students is 12 + 8 = 20.
To find the class average, we divide the total number of points by the total number of students:
average = total points / total students
average = 1664 / 20
average = 83.2
Therefore, the class average is 83.2 points.

Jordan has gone into the nut business. He wants to make a mixture of walnuts and cashews that cost $1.00 per pound. How many pounds of walnuts that cost $0.80 per pound must be mixed with 8 pounds of cashews that costs $1.25 per pound to make his mixture of nuts cost $1.00 per pound?
A. 16 lbs
b. 11 lbs
c. 20 lbs
d. 10 lbs
Answer:
The answer is (d) 10 lbs.
Step-by-step explanation:
Let's start by using the weighted average formula:
weighted average price = (price of first item x weight of first item + price of second item x weight of second item) / total weight
Let x be the number of pounds of walnuts needed.
The total weight of the mixture is x + 8 pounds.
The price of the walnuts is $0.80 per pound, and the price of the cashews is $1.25 per pound.
We want the mixture to cost $1.00 per pound.
Using the formula, we get:
1.00 = (0.80x + 1.25(8)) / (x + 8)
Simplifying, we get:
1.00(x + 8) = 0.80x + 10
1.00x + 8.00 = 0.80x + 10.00
0.20x = 2.00
x = 10
Therefore, Jordan needs to mix 10 pounds of walnuts with 8 pounds of cashews to make a mixture that costs $1.00 per pound.

The measures of the angles are 33°, 105° and 42°
We can call the top angle P, the bottom left angle Q, and the bottom right angle R. We are also given that angle P is (x - 9) degrees, angle Q is (x + 63) degrees, and angle R is x degrees.
Now, we can use the fact that the sum of the angles in a triangle is 180 degrees to set up an equation:
Angle P + Angle Q + Angle R = 180
To find Angle, we can use the fact that the sum of the angles in a straight line is 180 degrees. We can see that Angle and Angle A are on a straight line, so we have:
(x – 9) + ( x + 63) + x = 180
=> 3x + 54 = 180
=> 3x = 126
=> x = 42
We can now use this value to find the measures of the angles.
Angle P is (x -9) degrees, so Angle P = 42 - 9 = 33 degrees.
Angle Q is (x + 63) degrees, so Angle Q = 42 + 63 = 105 degrees.
Angle R is x degrees, so Angle R = 42 degrees.

The opposite of an integer is the number on the opposite side of the number line with the same distance from zero. So, the integers that are opposites are 14 and -14, 17 and -17, 32 and -32, and 15 and -15. This is because these pairs have the same absolute value but different signs. For instance, the absolute value of 14 is 14, and the absolute value of -14 is also 14. Therefore, -14 is the opposite of 14. Similarly, -17 is the opposite of 17 and so on.

The solution is, 7980 times greater is the value represented by the digit 8 in the number 8,342 than the value represented by the digit 8 in the number 284.
Here, we have,
given that,
the value represented by the digit 8 in the number 8,342
and, the value represented by the digit 8 in the number 284.
now, we have to find that how many times greater is the value.
so, we have to differentiate the value represented by the digit 8 in the number 8,342 with the value represented by the digit 8 in the number 284.
so, we get,
the value represented by the digit 8 in the number 8,342 is 8000
and, the value represented by the digit 8 in the number 284 is 80
so, difference between them is:
8000 - 80

As the class sizes range from 22 to 34 students, the answer must be 30,
Let the number of girls in the class "3x" and the number of boys "7x".
Then the total number of students in the class is:
Total students = 3x + 7x = 10x
We don't know the value of "x" yet, but we do know that the total number of students is between 22 and 34.
So we can set up an inequality:
22 ≤ 10x ≤ 34
Divide both sides of the inequality by 10:
2.2 ≤ x ≤ 3.4
Therefore, x can be either 3 or 4.
If x = 3, then the total number of students is:
Total students = 3x + 7x = 30
If x = 4, then the total number of students is:
Total students = 3x + 7x = 40
