Point of y-intercept is (0,1)
What is y-intercepts?In a graph, the point where the line or curve crosses the axis is called the intercept. If a point crosses the x-axis it is x-intercepts. If a point crosses y-axis it is y-intercepts.
Given the function is [tex]y=2.5^{x}[/tex]
y-intercept is the point where the graph of the function crosses the y-axis.
To find the point of y-intercept put x=0 in the given function, we get
if x=0 then [tex]y=2.5^{0}[/tex] ⇒ y=1.
The function crosses at the point 1 in the y-axis.
Hence, point of y-intercept is (0,1)

Use the expression (8x + 2) + (-9x + 7).
a. Find the sum.
b. Reasoning Explain how you know when to combine terms with variables.
Answers
Answer:
-x + 9
Step-by-step explanation:
Addition of expression:a)
8x + 2 + (-9x + 7) = 8x + 2 - 9x + 7
= 8x - 9x + 2 + 7
= -x + 9
b) We can combine like terms. Like terms have same variable with same power. Here 8x and (-9x) have same variable 'x'. so, combine the coefficients of the like terms which give (-1).
8x - 9x = -1
Combine the constants. 2 + 7= 9

Part III: Use the point given for line p and the slope you found in Part II to write an
equation for line p in point-slope form: Y-Y₁ = m(x-x₁). (1 point)
Answers
The slope of line q is equal to 3.
The slope of line q is equal to -1/3.
An equation for line p in point-slope form is y + 5 = -1/3(x - 6).
An equation for line p in slope-intercept form is y = -1/3x - 3.
What is the slope-intercept form?Mathematically, the slope-intercept form of the equation of a straight line is given by this mathematical expression;
y = mx + c ....equation 1.
Where:
m represents the slope.x and y are the points.c represents the y-intercept or initial value.From the information provided, we have the following linear equation in slope-intercept form for line q:
y = 3x + 5 ....equation 2.
By comparing equation 1 and equation 2, we can logically deduce the following:
Slope (m) = 3
Since line p is perpendicular to line q, the slope of line p is the negative reciprocal of the slope of line q;
m₁ × m₂ = -1
3 × m₂ = -1
Slope, m₂ of line p = -1/3.
At data point (6, -5), a linear equation of this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y - (-5) = -1/3(x - 6)
y + 5 = -1/3(x - 6)
By simplifying further, the slope-intercept form is given by;
y + 5 = -1/3(x - 6)
3y + 15 = -x + 6

Answers
The value of the probabilities are
a. P(x ≥ 12.5) is 6.68%
b. P(x ≤ 9) is 2.28%
c. P(10.88 ≤ x ≤ 15.3) is 61.38%
d. P(4.72 ≤ x ≤ 12.46) is 99.45%
Probability is the measure of the likelihood of an event occurring. It is a way of quantifying uncertainty and predicting the likelihood of an outcome. In this question, we will use the normal distribution to calculate probabilities.
The mean is the center of the distribution, and the standard deviation measures the spread of the distribution.
a. P(x ≥ 12.5):
Using a standard normal distribution table, we find that the area to the right of 12.5 is 0.0668. This means that the probability of x being greater than or equal to 12.5 is 0.0668 or 6.68%.
b. P(x ≤ 9):
Using a standard normal distribution table, we find that the area to the left of 9 is 0.0228. This means that the probability of x being less than or equal to 9 is 0.0228 or 2.28%.
c. P(10.88 ≤ x ≤ 15.3):
Using a standard normal distribution table, we find that the area to the left of 15.3 is 0.9987 and the area to the left of 10.88 is 0.3849. Therefore, the area between 10.88 and 15.3 is
=> 0.9987 - 0.3849 = 0.6138.
This means that the probability of x being between 10.88 and 15.3 is 0.6138 or 61.38%.
d. P(4.72 ≤ x ≤ 12.46):
Using a standard normal distribution table, we find that the area to the left of 12.46 is 0.9946 and the area to the left of 4.72 is 0.0001. Therefore, the area between 4.72 and 12.46 is
=> 0.9946 - 0.0001 = 0.9945.
This the probability of x being between 4.72 and 12.46 is 0.9945 or 99.45%.

Answers
As per the information provided, option B) The errors e1,e2, e; have the same variance is the assumptions for linear regression.
Regression analysis is a linear technique used to model the relationship between a scalar response and/or one or more explanatory variables, also known as the dependent and independent variables here.
Simple linear regression and multiple linear regression are two terms used to describe the process when there is only one explanatory variable present. This statement is different from multivariate linear regression, which thus predicts multiple correlated dependent variables as opposed to a single scalar variable present.
The first regression analysis technique that attracted a lot of research attention and was frequently applied in practical situations was linear regression. This is because models with linear rather than non-linear dependence on their unknown parameters are easier to fit, and it is also easier to determine the statistical properties of the resulting estimators.

Answers
The height of the triangle is 20 and base of the triangle is 12.
"Information available from the question"
The base of a triangle is 8 ft. less than its height.
If the area is 120 [tex]ft^2.[/tex]
We have to find the base and the height of this triangle.
Now, According to the question:
Let the height be x then if the base is 8 ft. less, then the base is x - 8.
We know that:
Area of the triangle is : (b × h)/2
Area of the triangle is : (x (x - 8)) /2
120 [tex]ft^2[/tex] = ([tex]x^{2} -8x[/tex])/2
240 = [tex]x^{2} -8x[/tex]
[tex]= > x^{2} -8x-240=0[/tex]
For solving equation, Use the quadratic formula :
x = (-b ± [tex]\sqrt{b^2-4ac}[/tex]) / 2a
a = 1
b = -8
c = -240
x = (-(-8) ± [tex]\sqrt{(-8)^2-4.1(-240)})/2.1[/tex]
By solving, we get
x = (8 ± 32)/2
We get the values :
x = 20 and x = -12
We know x = −12 can't be a solution as length can't be negative.
Base = x - 8
Base = 20 - 8
Base = 12
Hence, The height of the triangle is 20 and base of the triangle is 12.

You use the deduction method - C and D clearly can't be the correct answers since there's only 22 papers there, somehow, so the only valid potential answers are A and B.
B cannot be it, since she took k papers at home and took extra 24, meaning that would be 24 + k.

A rectangle has a length of 30 feet less than five times its width if the area of the rectangle is 360 ft.² find the length of the rectangle
Answers
Answer:
[tex]l = 30[/tex] OR [tex]l=-60[/tex]
Step-by-step explanation:
We can solve this problem with a system of equations by creating 2 equations from the information given.
1. "a length of 30 feet less than 5 times its width"
[tex]l = 5w - 30[/tex]
2. "the area of the rectangle is 360 ft²"
[tex]l\cdot w = 360[/tex]
To solve for the rectangle's length, we can create a substitution for w by dividing both sides of the second equation by length ([tex]l[/tex]).
[tex]l\cdot w = 360\\\overline{\ \ l\ \ } \ \ \ \: \ \overline{\ l \ \ }[/tex]
[tex]w = \dfrac{360}{l}[/tex]
Then, we can substitute this value back into the first equation and solve for [tex]l[/tex].
[tex]l = 5(\dfrac{360}{l}) - 30[/tex]
↓ distribute the 5
[tex]l(l) = \left(\dfrac{1800}{l} - 30\right)l[/tex]
↓ multiply both sides by [tex]l[/tex]
[tex]l^2 = 1800 - 30l[/tex]
↓ move all [tex]l[/tex]'s to one side
[tex]l^2 + 30l = 1800[/tex]
To solve this quadratic, we can complete the square.
↓ add (30/2)² to both sides
[tex]l^2 + 30l + \left(\dfrac{30}{2}\right)^2 = 1800 + 15^2[/tex]
↓ simplify 15²
[tex]l^2 + 30l + 225 = 1800 + 225[/tex]
↓ factor the left side as a perfect square
[tex](l + 15)^2 = 2025[/tex]
↓ take the square root of both sides
[tex]l + 15 = \pm \sqrt{2025}[/tex]
[tex]l + 15 = \pm 45[/tex]
↓ split into 2 equations
[tex]l + 15 = 45[/tex] OR [tex]l + 15 = -45[/tex]

Six friends group is playing poker one night. They have a standard 52-card deck. So, here, total number of possible outcomes of game = 52
Now, the designated cards are , Queen of Clubs, 10 of Hearts. So,
a) Number of cards are in the deck that are not one of the designated cards

b) Number of cards are in the deck = 52
Number of cards that need to be dealt in order for each player to have 7 cards = 5× 7 = 35
Thus total possible number of ways

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.
Given is Sam's fathers collection.
We can write the equations for upstream and downstream as -
x - y = 7/2
x + y = 21/10
Solving the equations graphically -
{x} = 2.8
{y} = 0.7
In still water, the speed would be -
S = 3 - 0.7
S = 2.3 Km/h
Distance peddled upstream -
D = 2.8 x 3.5 = 9.8 Km
Therefore, the speed in still water would be 2.3 Km/h and the distance peddled upstream would be 9.8 Km.

a) The determination of the dividends per share for the cumulative preferred and common stock for each year is as follows:
Preferred StockDividends per share
2011 $3.00
2012 $1.20
2013 $4.80
Common StockDividends per share
2011 $1.50
2012 $0
2013 $2.10
b) The determination of the amount of current dividends that preferred stock should receive per year is $75,000.
What is cumulative preferred stock?Cumulative preferred stock is a special class of preferred stock that enjoys cumulative dividends.
Cumulative dividends imply that any year when sufficient dividends are not declared, the arrears are carried forward to subsequent years.
It is the opposite of non-cumulative preferred stock.
On the other hand, the common stockholders can only receive dividends after the preferred stockholders have been paid, including their cumulative dividends.
Cumulative Preferred Stock:Number of shares = 25,000
Dividend rate = 2%
Par value = $150
Total cumulative preferred stock = $3,750,000 (25,000 x $150)
Annual dividend = $75,000 ($3,750,000 x 2%)
Common Stock:Number of shares = 50,000
Par value = $15
Total common stock = $750,000 (50,000 x $15)
Preferred StockDividends Due (Dividends per share)
2011 $75,000 $3 ($75,000/25,000)
2012 $30,000 $1.2 ($30,000/25,000)
2013 $120,000 $4.8 ($120,000/25,000)

What are similar triangles?Similar triangles are triangles that share these two features presented as follows:
Congruent angle measures.Proportional side lengths.For each flagpole, the parameters are given as follow:
Flagpole a: Distance of 12 - 10 = 2 ft, height of 13.2 ft.Flagpole c: Distance of 10 ft, height of h ft.The triangles are similar, hence the proportional relationship to obtain the height of flagpole's c is given as follows:
2/10 = 13.2/h
Applying cross multiplication, the height is obtained as follows:
2h = 10 x 13.2.
h = 132/2
h = 66 ft.

6. Write the unit rate for the following: a) Kate sews 100 dresses in a 20 day month. b) Kim runs 5 km in 30 minutes.
Answers
a) The unit rate of Kate's sewing productivity can be found by dividing the number of dresses by the number of days:
Kate sews 100 dresses in 20 days.
The unit rate is 100 dresses / 20 days = 5 dresses per day.
b) The unit rate of Kim's running speed can be found by dividing the distance by the time:
Kim runs 5 km in 30 minutes.
The unit rate is 5 km / 0.5 hour = 10 km/hour.
Therefore, the unit rate for Kate's sewing productivity is 5 dresses per day, and the unit rate for Kim's running speed is 10 km/hour.
