1. Professor Cramer determines a final grade based on attendance, two papers, three major tests, and a final exam. Each of these activities has a total of 100 possible points. However, the activities carry different weights. Attendance is worth 3%, each paper is worth 6%, each test is worth 19%, and the final is worth 28%.
(a) What is the average for a student with 81 on attendance, 62 on the first paper, 86 on the second paper, 78 on test 1, 68 on test 2, 68 on test 3, and 87 on the final exam? (Round your answer to one decimal place.)
(b) Compute the average for a student with the above scores on the papers, tests, and final exam, but with a score of only 17 on attendance. (Round your answer to one decimal place.
Answers
Answer:
Ur final grade will go down if you are looking for answers buddy! :)
Step-by-step explanation:
a) The average for a student with the given scores is 76.3 (rounded to one decimal place).
b) The average for a student with the given scores, but with a score of only 17 on attendance, is 74.4 (rounded to one decimal place).
Here, we have,
To calculate the average for the given scores, taking into account the different weights of each component, we can use the following steps:
(a) Average with the given scores:
To calculate the average with the given scores, we multiply each score by its respective weight, then sum up the results.
Here's the calculation:
Average = (Attendance * 0.03) + (First Paper * 0.06) + (Second Paper * 0.06) + (Test 1 * 0.19) + (Test 2 * 0.19) + (Test 3 * 0.19) + (Final Exam * 0.28)
Substituting the given scores:
Average = (81 * 0.03) + (62 * 0.06) + (86 * 0.06) + (78 * 0.19) + (68 * 0.19) + (68 * 0.19) + (87 * 0.28)
Average = 2.43 + 3.72 + 5.16 + 14.82 + 12.92 + 12.92 + 24.36
Average = 76.33
Therefore, the average for a student with the given scores is 76.3 (rounded to one decimal place).
(b) Average with a score of 17 on attendance:
Using the same calculation method as above, substituting the attendance score:
Average = (17 * 0.03) + (62 * 0.06) + (86 * 0.06) + (78 * 0.19) + (68 * 0.19) + (68 * 0.19) + (87 * 0.28)
Average = 0.51 + 3.72 + 5.16 + 14.82 + 12.92 + 12.92 + 24.36
Average = 74.41
Therefore, the average for a student with the given scores, but with a score of only 17 on attendance, is 74.4 (rounded to one decimal place).

Which expression is equivalent to 20+64
a.4+(16+60)
b.4+(5+16)
c.4+(16+60)
d.4(5+16)
Answers
Answer:
D. 4 (5 + 16)
Step-by-step explanation:
20 + 64 = 84
To solve this problem we have to simplify each of the expressions in the answer column:
A. = 80
(16 + 60 = 76) giving us
4 + 76 = 80
B. = 25
(5 + 16 = 21)
4 + 21 = 25
C. = 80
(16 + 60 = 76)
4 + 76 = 80
D. = 84
(5 + 16 = 21)
4 x 21 = 84
So The correct option is D. 4 (5 + 16)

Duncan and his family are season ticket holders for their favorite baseball team. Last year, the cost of season tickets was $2,730. This year, the cost is $3,333.80. What was the percent of increase in the cost of season tickets?
Round your answer to the nearest tenth of a percent.
Answers
Answer:
10%
Step-by-step explanation:
To find the answer we need to know what percentage of $1030 is $927 and to do this we can multiply 927 by 100 and divide by 1030.
(927(100))/1030
92700/1030
90
so now that we know $927 is 90% of $1030 we can subtract 90 from 100 and it'll give us the percentage decrease. Which is 10%.

if AB=BA= I then write the relation between matrix A and matrix B
Answers
Answer:
If AB = BA = I, then B is inverse of A and vice-versa.
Step-by-step explanation:
Given: AB = BA = I
To find: The relation between matrix A and B.
If AB = BA = I, then B is called the inverse matrix of A and is denoted by [tex]A^{-1}[/tex].
In that case, A is said to be invertible.
Also, if B is the inverse of A, then A is also the inverse of B.
Hence, the relation between A and B is that both are inverse of each other.

What is the approximate volume of the cylinder?Use 3.14 for Pie
A)904.32cm_3
B)226.08cm_3
C)301.44cm_3
D)150.72cm_3
Answers
Answer:
The volume of cylinder: r squared times pi times height= 1.2 times 1.2 times pi times 20 = 1.44 times pi times 20 which is around 90.48 meters squared. Volume of water: r squared times pi times height = 1.2 times 1.2 times pi times 1 = 1.44 times pi which is around 4.52 meters squared.
The volume of the cylinder is 904.32 cubic cm if the radius is 6 cm and height of the cylinder is 8 cm option (A) is correct.
What is a cylinder?In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.
We know the volume of the cylinder is given by:
[tex]\rm V = \pi r^2 h[/tex]
Here r = 6 cm
h = 8 cm
π = 3.14
The volume of the cylinder:
[tex]\rm V = 3.14 \times(6)^2 \times 8[/tex]
V = 904.32 cubic cm
Thus, the volume of the cylinder is 904.32 cubic cm if the radius is 6 cm and height of the cylinder is 8 cm option (A) is correct.
