Answer:
the mode that repeats the most is 2.2 becuase to find it you need to find the number that repeats the most in the table. To find the median you add all the numbers and divide them to get the answer that is 2.7 for the mean but to find the median you need to order them from least to greatest and the answer you get for the median is 2.6 so hopefully that is the correct answer for all of them.

1. Ben earns $12,800 a year. About 15% is taken out for taxes. How much is taken out for taxes?
2. Manuel found a wrecked Trans-Am that he could fix. He bought the car for 65% of the original price of $7200. What did he pay for the car?
3. A woman put $580 into a savings account for one year. The rate of interest on the account was 6½%. How much was the interest for the year in dollars and cents?
4. A student earned a grade of 80% on a math test that had 20 problems. How many problems on this test did the student answer correctly?
5. There are 28 students in a class. Sixteen of those students are men. What percent of the class are women?
Answer:
1 multiply 12,800 x 15 = 192,000 then divide 192,000 by 100 = 1,920 so the answer is $ 1,920
2 He paid $7200 for the wrecked car which is about 65% of the original price.
3Hence, interest over a year is $ 37.7 or 3770 cents.
4 The student answered 16 problems correctly on a math test that had 20 problems.
5 Total students in the class = 28
Number of students that are men = 16
Number of student that are women = 28 - 16 = 12
percentage of women in the class = 12 / 28 × 100
percentage of women in the class = 1200 / 28
percentage of women in the class = 42.8571428571
percentage of women in the class ≈ 42.9 %

Answer:
1/16 chance

All 16 possibilities of combinations are listed in the question. Since we do not know which option is the correct one, there is a 1/16 chance that the student will get all four questions right, as that is a single combination out of 16.

Lin and Andre used different methods to find the area of a regular hexagon with 6-inch sides. Lin decomposed the hexagon into six identical triangles. Andre decomposed the hexagon into a rectangle and two triangles.
Find the area of the hexagon using each person’s method. Show your reasoning.
Answer:
108inches^2
Step-by-step explanation
.............................................
Divide the hexagon in identical triangles.
Triangle area = length × width / 2
6 × 6 = 36
36/2= 18
The area of a regular hexagon is 85.28 square inches.
Given that, Lin and Andre used different methods to find the area of a regular hexagon with 6-inch sides.
We need to find the area of a hexagon using both methods.
What is the area of a regular hexagon?The formula for the area of a regular hexagon is (3√3 s²)/2, where 's' is the length of the side of the hexagon. Since we are talking about a regular hexagon, it should be noted that all sides are of equal length. When one side of the regular hexagon is known, the area can be calculated with the formula, Area of the hexagon = (3√3 s²)/2, where 's' is the length of the side of the hexagon.
We know that, the area of an equilateral triangle=√3/2 × a².
So, the area of an equilateral triangle= √3/2 × 6²
=18√3 square inches
Now, the area of a hexagon=6×18√3
=108√3=187.06 square inches
Area of the rectangle = length × width = 10.4 × 6 = 62.4 square inches
Area of a triangle= 1/2 × Base × Height = 1/2 × 10.4 × 2.2 = 11.44 square inches
Now, 11.44 × 2=22.88
Area of a regular hexagon = 62.4+22.88 =85.28 square inches
Therefore, the area of a regular hexagon is 85.28 square inches.

A computer is used to generate passwords made up of numbers 0 through 9 and uppercase letters. The computer generates 500 passwords one character at a time.
A uniform probability model is used to predict the first character in the password.
What is the prediction for the number of passwords in which the first character is a number?
Round your answer to the nearest whole number.
69 passwords
139 passwords
192 passwords
292 passwords
Answer:
139
Step-by-step explanation:
Just took the quiz on K-12
Hope its not to late
The prediction for the number of passwords in which the first character is a number is 139. Therefore, option B is the correct answer.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
The answer is 192 passwords. This is because there is an equal probability of each character (0-9 and uppercase letters) being chosen as the first character of a password.
Since there are 10 different numbers (0-9) and 26 uppercase letters, the probability of the first character being a number is 10/36
If 500 passwords are generated, the expected number of passwords in which the first character is a number is 500 ×10/36
= 5000/36
= 138.88
≈ 139
Therefore, option B is the correct answer.
