The correct option c: Subjective Probability, defined by teacher estimated that 95% of the Senior class would attend the prom.
What is termed as the Subjective Probability?The probability of a situation expresses the possibility or chance that the event will occur as a number ranging from zero to one (or 0% and 100%), with zero indicating an impossible outcome and 1 representing a certain outcome. The calculated value of the probability could be calculated in a variety of ways.The subjective probability meaning is establishing the likelihood of a situation based solely on one's own opinion or belief, rather than on any observational data or calculations. Although this opinion may be informed by prior experience or specific observations, subjective probability is eventually just a personal preference. As a result, it is also referred to as personal probability.For the given question,
As the probability estimated by the teacher that 95% of the Senior class would attend the prom, is the personal opinion.
Thus, the given case is of Subjective Probability.

The given equation represents the equation of a parabola and it represents the curve open up with vertex (-3, -4).
Hence, option A is correct.
A parabola is a U-shaped plane curve in which any point is an equal distance from both a fixed point (known as the focus) and a fixed straight line (known as the directrix).
The given equation is:
y = (x +3)² - 4
Since we know that,
An equation of the parabola is
y = a(x - h)² + k
Where (h, k) is the vertex.
Comparing these equations we get
a = 1
h = -3
k = -4
So, its vertex is (h, k) = (-3, -4)
Hence,

Graph the inequality on the axes below. y≥3/2x-1
The graph will be a shaded region above and including the straight line y = (3/2)x-1.
We are asked to graph the inequality y ≥ (3/2)x-1. Describing the graph of an inequality, it will be a region on one side of a straight line.
So first we need to sketch the straight line, y = (3/2)x-1.
So find two points (x, y) satisfying this equation of line because a line need at least two points.
x y
0 -1
2/3 0
So first sketch a line joining the points (0, -1) and (2/3,0). This line will lie below the origin. That is, origin lies on the region above this line.
So the line y = (3/2)x-1 divided the plane into two regions, one of which represents the inequality y ≥ (3/2)x-1. So to find this required region we will check if origin lies in the region for inequality.
Substituting (0, 0) into y ≥ (3/2)x-1,
0 ≥ -1, which is true.
Thus in the graph, the region for inequality is the region where the origin lies. Hence shade the region above the line y = (3/2)x-1. This is the graph of the inequality y ≥ (3/2)x-1.

What is a an arithmetic sequence?An arithmetic sequence is a group of numbers in which the difference between subsequent terms is a constant
1. The given parameters are;
The initial amount Savannah placed in the piggy bank = 5 pennies
The amount given to Savannah each day = 3 pennies
Required;
First part;
The amount Savannah will have after 10 days
Solution;
The mathematical model for the situation is an arithmetic sequence or progression
The equation for an arithmetic progression is;
[tex]a_n = a_1 + (n - 1) \times d[/tex]
Where;
[tex]a_n[/tex] = The amount after n days
[tex]a_1 [/tex] = The first amount Savannah placed in the piggy bank = 5 pennies
n = The number of days
d = The common difference between the amount present in consecutive days = 3 pennies
The amount after 10 days is therefore;
[tex]a_{10} = 5 + (10 - 1) \times 3=32[/tex]
The money after 10 days is 32 pennies
Second part;
The number of days it would take for there to be $1.50 in the piggy bank.
Solution;
100 pennies = $1.00
Therefore;
$1.50 = 150 pennies
Which gives;
150 = 5 + (n - 1) × 3
(n - 1) × 3 = 150 - 5 = 145
(n - 1) × 3 = 145
n - 1 = 145 ÷ 3
n = 145 ÷ 3 + 1 ≈ 49.3 ≈ 50
It will take approximately 50 days for the amount in the piggy bank to be $1.50
2. The volume of the pool = 1,500 gallons
The initial amount of water in the pool = 5 gallons
The rate at which water enters the pool = 2 gallons in 5 minutes
Required;
First part
The volume of water in the pool after 50 minutes
Solution;
2 gallons in 5 minutes = (2/5) gallons/minute = 0.4 gallons/minute
Therefore;
[tex]a_{50} = 5 + (50 - 1) \times 0.4 =24.6[/tex]
After 50 minutes, 24.6 gallons will be in the pool
Second part;
The time it will take to fill the pool is given by the equation;
[tex]1500 = 5 + (n - 1) \times 0.4[/tex]
number
Which gives;
n = 3738.5
It will take 3,738.5 minutes to fill the pool
3. The formula for finding the amount in the account is the compound interest formula;
[tex]\displaystyle{A = P\cdot (1 + r)^n }[/tex]
Where;
A = The amount in the account after n months
P = The initial amount in the account = $50.0
r = The interest rate = 3.0%
n = The number of periods (months)
After 10 months, we have;
[tex]\displaystyle{A = 50 \times (1 + 0.03)^{10} \approx 67.2 }[/tex]
The amount in the account after 10 months is therefore, approximately $67.2
Second part;
Double the initial amount is 2×$50 = $100
Which gives;
[tex]100 = \displaystyle{50 \times (1 + 0.03)^{n} \approx 67.2 } [/tex]
Which gives;
n ≈ 23.45
Therefore it will take approximately 23.45 months or approximately 24 months for the amount to double
4. Using the exponential function formula, we have;
Number of 5 minutes in 50 minutes = 10
[tex] \displaystyle{1500 \times (1 - 0.03)^{10} \approx 1106.14} [/tex]
The water remaining after 50 minutes is approximately 1106.14 gallons
The time it takes for there to be less than 1,000 gallons in the pool is given as follows;
[tex] \displaystyle{ 1000= 1500 \times (1 - 0.03)^{n}} [/tex]
Which gives;
n = 13.3
Therefore;
The water in the pool will be less than 1000 gallons after 13.3, 5 minute periods or 13.3 × 5 minutes≈ 66.56 minutes

The sum of three mixed numbers is 24 4/5. Two of the number are 8 2/3 and 6 5/6. What is the third number?
The numerical value of the third number in an improper and mixed fraction form is 93/10 and 9 3/10 respectively.
What is the value of the third number?Given the data in the question;
Let 'x' represent the third number
Sum of the three numbers = 24 4/5First number = 8 2/3Second number = 6 5/6Third number = xFirst, convert the numbers form mixed fractions to improper fractions
Sum of the three numbers = 24 4/5 = ( 24×5 + 4 )/5 = 124/5
First number = 8 2/3 = ( 8×3 + 2 )/3 = 26/3
Second number = 6 5/6 = ( 6×6 + 5 )/2 = 41/6
Now, to determine the third value, equate the sum of the three numbers to the total and solve for x
26/3 + 41/6 + x = 124/5
( 156 + 123 )/18 + x = 124/5
( 279 )/18 + x = 124/5
31/2 + x = 124/5
x = 124/5 - 31/2
x = ( 248 - 155 )/10
x = ( 93 )/10
x = 93/10
x = 9 3/10
Therefore, the value of the third number is 93/10 or 9 3/10.

The multiples of 4 between 100 and 150
Answer:
104 ;108;112;116;120;124;128;132;136 ;140;144;148
Answer:
104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 144, 148
Step-by-step explanation:
A multiple of 4 can generally be defined as divisible by 4.
We can define an equation for it: [tex]4n[/tex] where n is an integer.
From here we can see that if n=25, we have a number of 100 which indeed is a multiple of 4 since dividing it by 4 results in 25 which makes sense since 100 is the result of 4 * 25.
Now starting from 100 (excluding 100 since between 100 and 150), or n=25, we can increase the value of the number by 4, or n by 1 which is doing the same thing.
So start at 100, then 100+4 = 104, then 104+4=108 and so on... until you reach a number greater than or equal to 150, and if it is 150 make sure to exclude it since it says between 100 and 150 which implies it's excluding the end points.
This gives us a result of: 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 144, 148
