In Tasheena's Anthropology class Quizzes are worth 15% of the final grade, Exams are worth 55%, Projects are worth 25%, and Attendance is worth 5%.
At mid-semester Tasheena scored 117 out of 150 points on quizzes, 74, 86, and 91 on the first three exams,each worth 100 points. She got extra credit on her project with a score of 29 out of 25 possible points, and she had perfect attendance to class. Compute Tasheena's grade percentage in the class so far.
Tasheena's grade percentage in the class so far is approximately 71.00935%.
How do you find percentages?The percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.
To compute Tasheena's grade percentage in the class so far, we can calculate the weighted average of her scores based on the weightage of each component of the final grade.
Given:
Quizzes: 15% weightage
Exams: 55% weightage
Projects: 25% weightage
Attendance: 5% weightage
Tasheena's scores:
Quizzes: 117 out of 150 points
Exams: 74, 86, and 91 on the first three exams (each worth 100 points)
Projects: 29 out of 25 possible points
Attendance: Perfect attendance
Let's calculate Tasheena's grade percentage:
Quizzes:
Tasheena's quiz score percentage = (117 / 150) * 100 = 78%
Exams:
Tasheena's exam average = (74 + 86 + 91) / 3 = 83.67
Tasheena's exam score percentage = (83.67 / 100) * 55 = 46.017%
Projects:
Tasheena's project score percentage = (29 / 25) * 100 = 116%
Attendance:
Tasheena's attendance score percentage = 100% (since she had perfect attendance)
Now, let's calculate the weighted average of Tasheena's scores:
Weighted average = (Quizzes weightage * Quiz score percentage) + (Exams weightage * Exam score percentage) + (Projects weightage * Project score percentage) + (Attendance weightage * Attendance score percentage)
= (15% * 78%) + (55% * 46.017%) + (25% * 116%) + (5% * 100%)
= 11.7% + 25.30935% + 29% + 5%
= 71.00935%
Hence, Tasheena's grade percentage in the class so far is approximately 71.00935%.

Find the length of the third side. if necessary, round to the nearest tenth of 1 and 3
Using the Pythagorean theorem we know that the third side is 15 units.
What is the Pythagorean theorem?The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry.
The Pythagorean Theorem states that the squares on the hypotenuse (the side across from the right angle) of a right triangle, or, in standard algebraic notation, a² + b², are equal to the squares on the legs.
To determine c, use the Pythagorean Theorem as follows:
a² + b² = c²
9² + 12² = c²
81 + 144 = c²
225 = c
c² = 225
c = √(225)
c = 15
Therefore, using the Pythagorean theorem we know that the third side is 15 units.

scheduled payment of $1010 due five months ago and $1280 due today are to be repaid by a payment of $615 in four month and the balance in seven months. If money is worth 7.75% p.a , and the focal date is in seven months, what is the amount of the final payment?
The amount of the final payment is $1,004.99.
To solve the given problem, we will use the concept of present value. We need to find the present value of the two payments due in the past, and then find the future value of the remaining payments due in the future.
Let's first find the present value of the two past payments:
PV1 = $1010 / (1 + 0.0775/12)⁵ = $868.15
PV2 = $1280 / (1 + 0.0775/12)⁰ = $1280
Next, we can find the future value of the remaining payments due in the future
FV1 = $615 x (1 + 0.0775/12)⁴ = $664.69
FV2 = X
Now we can set up an equation to solve for X, the final payment:
PV1 + PV2 = FV1 + FV2 / (1 + 0.0775/12)⁷
Substituting the values we have calculated:
$868.15 + $1280 = $664.69 + X / (1 + 0.0775/12)⁷
Simplifying and solving for X
X = ($868.15 + $1280 - $664.69) x (1 + 0.0775/12)⁷ = $1,004.99
Therefore, the amount of the final payment is $1,004.99.

Based on the table, how many visitors will need to go to Jackson's Ice Cream shop on Saturday in order for the company to make a profit for the week?
A-108
B-110
C-122
D-222
Please add work/ explain!!
To find out how many visitors Jackson's Ice Cream Shop needs on Saturday to make a profit for the week, we need to first calculate the total number of visitors for the six days already given in the table. Then we can find out the number of visitors needed on Saturday to reach the required mean of 110 visitors per day for the week.
Total number of visitors for the six days = 63 + 77 + 121 + 96 + 137 + 154 = 648
To make a profit for the week, the total number of visitors for the entire week needs to be:
110 visitors/day × 7 days/week = 770 visitors/week
We already have 648 visitors for the six days, so the number of visitors needed on Saturday to make a profit can be found by subtracting the total number of visitors already counted from the total number of visitors needed for the week:
770 - 648 = 122
Therefore, the answer is (C) 122 visitors on Saturday are needed to make a profit for the week.
A department manager recently launched a new initiative so the members of her department can more easily present innovative ideas they have. To get feedback on the initiative, she emails a link to all department members for an anonymous online survey.
Which statement is true?
The statement that best describes the potential bias in this scenario is option B: The survey results are most at risk for department members not being able to answer honestly.
The reason for this is that department members may be afraid to share their true thoughts and opinions, especially if they believe their ideas may be seen as too innovative or risky. They may be concerned about how their managers or colleagues will perceive them if they express ideas that go against the status quo or challenge established norms.
This type of bias is known as social desirability bias, which refers to the tendency of respondents to answer questions in a way that is socially acceptable or desirable, rather than in a way that reflects their true beliefs or behaviors.
In this case, department members may feel pressure to conform to the expectations of their superiors or colleagues, even if it means not expressing their true opinions or ideas.

Show 2 different ways to find the value of x. What do you think is the most efficient method? Explain why.
We can use trigonometric relations or Pythagorean's theorem, we will see that x = 8ft.
How to find the value of x?We can see that x is the hypotenuse of the triangle, and we know the length of one leg and the angle between them, then we can use the cosine trigonometric relation:
cos(60°) = 4ft/x
solving for x:
x = 4ft/cos(60°) = 8ft
Other way to find x is first find the other side and then use the pyhtagorean theorem, to get the other side y we need:
tan(60°) = y/4ft
y = 4ft*tan(60°)
Then using Pythagorean's theorem we get:
x = √( (4ft)² + (4ft*tan(60°))²)

Let
u = 4i - j v = 3i + j w = i + 3j
Find the specified scalar.
u(v + w)
The specified scalar is 12 as the result of u(v + w) is 12i + 12j.
The provided vectors are given to be u = 4i - j v = 3i + j w = i + 3j. First, we need to find the vector v + w,
v + w = (3i + j) + (i + 3j)
v + w = 4i + 4j
Now, we can find dot product, u(v + w),
u(v + w) = u(4i + 4j)
u(v + w) = 4ui + 4uj
Substituting the given values of u, we get,
u(v + w) = 4(4i - j)i + 4(4i - j)j
u(v + w) = 16i - 4j + 16j - 4i
Simplifying, we get,

What are the coordinates of point S’?
Therefore, the coordinates of [tex]S'[/tex] are [tex](-2, -1)[/tex] .
What are coordinates?A series of numbers called coordinates is used to describe a point's location in a two- or three-dimensional space.
Typically, coordinates in a two-dimensional space are expressed as a pair of integers (x, y), where x denotes the point's horizontal location (also known as the abscissa) and y denotes its vertical position (also known as the ordinate).
Coordinates are commonly expressed as a triplet of numbers (x, y, z) in a three-dimensional space, where x, y, and z stand for the locations along the x, y, and z axes, respectively.
In order to describe the location of objects or points in space, coordinates are often employed in a variety of disciplines, including mathematics, physics, engineering, and computer graphics.
To rotate a point 180° about the origin, we need to negate the x-coordinate and the y-coordinate of the point.
So to find the coordinates of S', we can apply this rule to the coordinates of S:
x-coordinate of [tex]S' = -x-[/tex] coordinate of [tex]S = -(2) = -2[/tex]
y-coordinate of [tex]S' = -y-[/tex] coordinate of [tex]S = -(1) = -1[/tex]
