Tessa's cumulative GPA for all four semesters is 3.44.
To find Tessa's cumulative GPA, we first need to calculate the total number of course units she has taken. For the first three semesters, she took 46 course units. For the fourth semester, she took 12 course units. So, in total, she has taken 46 + 12 = 58 course units.
Next, we need to calculate her total grade points. To do this, we multiply her GPA for each semester by the number of course units she took in that semester, and then add up the results. For the first three semesters, her total grade points are:
3.35 x 46 = 154.1
For the fourth semester, her total grade points are:
3.74 x 12 = 44.88
So her total grade points for all four semesters are:
154.1 + 44.88 = 198.98
Finally, we divide her total grade points by the total number of course units she has taken:
198.98 / 58 = 3.44
Therefore, Tessa's cumulative GPA for all four semesters is 3.44.

The length BC of the bisected line segment is: 11.5
What is the length of the line after bisection?Usually a line that bisects a segment usually divides that segment into two equal parts.
Now, we are told that DE bisects Line AC at point B where AB = 3a + 4.
Thus, from the idea of a bisected segment, we can easily say that:
2(3a + 4) = a + 23
6a + 8 = a + 23
6a - a = 23 - 8
6a = 15
a = 15/6
a = 5/2
a = 2.5
Thus:
AB = BC = 3(2.5) + 4
BC = 11.5

The volume of the cylinder that has a diameter of 7 yards and a height of 12 yards is: 147π cubic yard.
What is the Volume of a Cylinder?The volume of a cylinder can be determined by applying the volume formula which is given as:
Volume (V) = πr²h,
where "r" is the radius of the cylinder
"h" is the height of the cylinder
π is a constant
Given the following:
Diameter of cylinder = 7 yards, thus, radius (r) = 7/2 = 3.5 yards
Height (h) = 12 yards

The least squares regression line was found. Using technology, it was determined that the total sum of squares (SST) was 11654 and the sum of squares of regression (SSR) was 11405.0.
The value of R² (coefficient of determination) is 0.0214
We know that the formula for the coefficient of determination is,
R² = 1 - (SSR / SST)
where, R² is the coefficient of determination
SST is the total sum of squares
SSR is the sum of squares of regression
Here, the total sum of squares (SST) = 11654
and the sum of squares of regression (SSR) = 11405
Using above formula,
R² = 1 - (SSR / SST)
R² = 1 - (11405 / 11654 )
R² = 1 - 0.9786
R² = 0.0214

The principal amount was £1260, and the annual interest rate is 5.5%.
Given that, Olivia gets £1606.50 and £1675.80 after 5 years and 6 years of investment in simple interest respectively.
SI = principal × rate × time / 100
So,
P + 5pr = £1606.50
P = £1606.50 - 5pr............(i)
P + 6pr = £1675.80
P = £1675.80 - 6pr.........(ii)
Therefore,
£1606.50 - 5pr = £1675.80 - 6pr
Pr = 69.3
Put the value of pr in eq(i)
P + 5(69.3) = 1606.50
P = 1606.5 - 346.5
P = 1260
Now,

A container built for transatlantic shipping is constructed in the shape of a right rectangular prism. Its dimensions are 2 ft by 2 ft by 12.5 ft. If the container is entirely full and, on average, its contents weigh 0.22 pounds per cubic foot, find the total weight of the contents. Round your answer to the nearest pound if necessary.
Answer:
38.81 pounds
Step-by-step explanation:
Considering the definition of right rectangular prism and its volume, the total weight of the contents is 38.81 pounds.
Right rectangular prism
A right rectangular prism (or cuboid) is a polyhedron whose surface is formed by two equal and parallel rectangles called bases and by four lateral faces that are also parallel rectangles and equal two to two.
Volume of right rectangular prism
To calculate the volume of the rectangular prism, it is necessary to find the product of its dimensions, or of the three edges that converge at a certain vertex.
That is, to calculate the volume of a rectangular prism, multiply its 3 dimensions: length×width×height.
Volume of the container
In this case, you know that:
the dimensions of the container built are 7.5 ft by 11.5 ft by 3 ft.
the container is entirely full and, on average, its contents weigh 0.15 pounds per cubic foot.
So, the volume of the container is calculated as:
7.5 ft× 11.5 ft× 3 ft= 258.75 ft³
Then, the total weight of the contents is calculated as:
258.75 ft³× 0.15 pounds per cubic foot= 38.8125 pounds≅ 38.81 pounds
Finally, the total weight of the contents is 38.81 pounds.

1.Non response and household bias
2.Sampling and household bias
3.Response and non response bias
4.Response and sampling bias
The correct answer is 3. Response and non-response bias.
Response bias occurs when the way that questions are asked or worded, or the context in which they are asked, influences how respondents answer them. This can lead to inaccurate or incomplete information being collected.
Non-response bias occurs when some individuals selected to participate in a survey do not respond. This can happen for various reasons, such as being unavailable, unwilling, or unable to participate. Non-response bias can skew the results of a survey because the characteristics of those who do not respond may differ from those who do respond.
In this scenario, the principal has asked all math and English teachers to rank his school leadership on a scale of 1 to 10. If some teachers do not respond to the survey or are unavailable, unwilling, or unable to participate, this could lead to non-response bias.
Additionally, if the principal has a reputation for being well-liked or well-respected, some teachers may feel pressured to give a higher rating than they otherwise would, which could lead to response bias.

A bag contains 3 black balls, 2 blue balls, and 3 green balls. A
random sample of 4 balls is selected. Given that x is the number of
black balls. y is the number of blue balls.
a) Find the joint probability function f(x, y)
b) Find the joint probability distribution of f(x, y)
The requreid, the joint probability function f(x, y) is:
f(0,0) = 3/14
f(0,1) = 9/28
f(0,2) = 3/28
f(1,0) = 9/28
f(1,1) = 9/28
f(2,0) = 3/14
f(2,1) = 3/14
f(3,0) = 1/14
To evaluate the joint probability function f(x, y), we need to determine the probability of selecting x black balls and y blue balls out of a sample of 4 balls. We can do this using the hypergeometric probability distribution formula:
f(x,y) = P(X = x, Y = y) = (C(3, x) * C(2, y) * C(3, 4-x-y)) / C(8, 4)
where C(n, k) represents the number of combinations of k items chosen from a set of n items.
Plugging in the values, we get:
f(0,0) = (C(3,0) * C(2,0) * C(3,4-0-0)) / C(8,4) = 3/14
f(0,1) = (C(3,0) * C(2,1) * C(3,4-0-1)) / C(8,4) = 9/28
f(0,2) = (C(3,0) * C(2,2) * C(3,4-0-2)) / C(8,4) = 3/28
f(1,0) = (C(3,1) * C(2,0) * C(3,4-1-0)) / C(8,4) = 9/28
f(1,1) = (C(3,1) * C(2,1) * C(3,4-1-1)) / C(8,4) = 9/28
f(2,0) = (C(3,2) * C(2,0) * C(3,4-2-0)) / C(8,4) = 3/14
f(2,1) = (C(3,2) * C(2,1) * C(3,4-2-1)) / C(8,4) = 3/14

find f(g(4)) and g(f(4)) given f(x)=2x-3 and g(x)=5x^2-4x+1
Answer:
g(f(4)) = 106.
Step-by-step explanation:
To find f(g(4)), we first need to find
g(4):g(4) = 5(4)^2 - 4(4) + 1 = 80 - 16 + 1 = 65
Now that we know g(4) is 65, we can find
f(g(4)):f(g(4)) = f(65) = 2(65) - 3 = 127
Therefore,
f(g(4)) = 127.
To find g(f(4)), we first need to find f(4):f(4) = 2(4) - 3 = 5
Now that we know f(4) is 5, we can find g(f(4)):
g(f(4)) = g(5) = 5(5)^2 - 4(5) + 1 = 125 - 20 + 1 = 106
Therefore, g(f(4)) = 106.

p = 77.6 cm
A = (15.2 cm) · (20 cm)
A = 304 cm²
Case 2

p = 25.1 ft
A = 0.5 · (10 ft) · (5.6 ft)
A = 28 ft²
Case 3

The vertices of a triangle are at (0,0), (8,8) and (4,12). What is the volume, in cubic units, of the figure created by rotating the triangle about y = x ?
The volume of the figure that was created by the triangle being rotated, would be 94. 83 units ³
How to find the volume ?When a triangle is rotated about y = x, a right circular cone is created. The formula is:
= π r² h / 3
We need to find the height and radius. The coordinates for the right circular cone are:
(0,0) - (0,0)
(8,8) - (8,8)
(4,12) - (12,4)
Using this, we find that the radius is 4 units. The height can be found by using any point such as ( 12, 4).
= √ ( ( 12 - 8) ² + ( 4 - 8 ) ²)
= 5. 66 units
The volume would therefore be:

The outlier in this data set is the sweatshirt priced at $18 since it is significantly higher than the rest of the prices.
How does the outlier affect the mean and median for the data set?The mean is affected more by outliers than the median.
In the provided data, the mean is higher than the median, which suggests that there may be an outlier pulling the average up. The outlier value of $18 is causing the mean to be higher.
If we remove the outlier value of $18, the mean price would be (6+12+11+15)/4 = $11, which is lower than the original mean of $12.40.
On the other hand, the median would remain the same since it is not affected by extreme values.
