if there is an 84% chance of an event happening in an hour, what is the probability that it happens in half an hour?
Answers
The probability of an event happening in half an hour cannot be determined simply by multiplying or dividing the probability of the event happening in an hour by a factor of 2.
Probabilities are not linear in that way. The probability of an event happening in half an hour would depend on the specific details of the event and the underlying probability distribution.
The probability of an event happening in half an hour, given an 84% chance of it happening in an hour, cannot be determined without additional information. The probability of an event occurring in half an hour would depend on the specific circumstances of the event and how the 84% probability was determined.

if there is an 84% chance of an event happening in an hour, then the probability that it happens in half an hour will be 84% = 0.84.
One cannot easily calculate the likelihood of an event occurring in half an hour by multiplying or dividing the chance of the event occurring in an hour by a factor of 2.
In that sense, probabilities are not linear. The likelihood of an event occurring in half an hour is determined by the event's specifics and the underlying probability distribution.
Without further information, the likelihood of an event occurring in half an hour given an 84% chance of occurring in an hour cannot be computed. The likelihood of an event occurring in half an hour is influenced on the event's unique circumstances and how the 84% probability was calculated.

(B) Use part (a) to find the least integer a so that an > 4n for all integers n ≥ a. (C) Prove by strong induction that an > 4n for all integers n ≥ a where a is the integer you chose in part (b). (D) Use part (a) to find the least integer b so that an > 45 for all integers n ≥ b. (E) Prove by strong induction that an > 5n for all integers n ≥ b where b is the integer you chose in part (d)
Answers
The first 8 terms of the sequence are 12, 16, 22, 30, 40, 52, 66, 82 respectively.
(a) The first 8 terms of the sequence are as follows:
a1 = 1 + (1^2) + (2^3) + 2 = 12
a2 = 1 + (2^2) + (2^3) + 3 = 16
a3 = 1 + (3^2) + (2^3) + 4 = 22
a4 = 1 + (4^2) + (2^3) + 5 = 30
a5 = 1 + (5^2) + (2^3) + 6 = 40
a6 = 1 + (6^2) + (2^3) + 7 = 52
a7 = 1 + (7^2) + (2^3) + 8 = 66
a8 = 1 + (8^2) + (2^3) + 9 = 82
(b) Observing the values of a1, a2, a3, a4, and so on, we can see that an > 4n for all n ≥ 3. Hence, a = 3.
(c) We will prove the statement "an > 4n for all integers n ≥ a" using strong induction.
Base case (n=3): a3 = 28 and 28 > 4 * 3 = 12, which is true.
Inductive step: Suppose an > 4n for all integers n = k (k ≥ 3). We need to show that a(k+1) > 4(k+1).
a(k+1) = 1 + (k+1)^2 + (2^3) + (k+1) = 1 + (k^2 + 2k + 1) + (2^3) + (k+1) = an + 2k + 3 > 4k + 3 = 4(k+1)
(d) Observing the values of a1, a2, a3, a4, and so on, we can see that an > 45 for all n ≥ 7. Hence, b = 7.
(e) We will prove the statement "an > 5n for all integers n ≥ b" using strong induction.
Base case (n=7): a7 = 120 and 120 > 7 * 5 = 35, which is true.
Inductive step: Suppose an > 5n for all integers n = k (k ≥ 7). We need to show that a(k+1) > 5(k+1).
a(k+1) = 1 + (k+1)^2 + (2^3) + (k+1) = 1 + (k^2 + 2k + 1) + (2^3) + (k+1) = an + 2k + 3 > 5k + 3 = 5(k+1)

Answers
The slope of the Function represents the change in height per day.
A line's slope in mathematics is defined as the ratio of the change in the y coordinates to the change in the x coordinate.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by Δy and Δx, respectively.
Consequently, the formula for the change in the y-coordinate with respect to the change in the x-coordinate is
[tex]m=\frac{dy}{dx}[/tex] = change in y/change in x
where "m" represents a line's slope.
Additionally, the slope of the line can be shown as
tan θ = Δy/Δx
So, the slope of a line is tanΘ.
So as slope represents a change in y per change in x, in the given question as y is height and x is days, slope changes in height per day.
The slope of the Function represents the change in height per day.

Answers
Answer:

Step-by-step explanation:
The students group has raised $1680 in the first three months.
Due of this, The Helping Hands Student Club decided to fundraise $4,000 by the end of the academic year.
How much is a percentage?
A percentage is a certain number or part in every hundred. It is a fraction with the denominator 100, and the symbol for it is "%."
It accomplishes 42% of its goal after three months.
The money raised over the initial three months is
42% of 4000
= 42/100 × 4000
= 42×40
= $1680
Thus, the students' group has raised $1680 in the first three months.

The quotient of the expression is 7x² + 8x + 1
How to determine the quotient of the expression?From the question, we have the following expression that can be used in solving the quotient
(7x^3-13x^2-23x-5)/(x-3)
Express properly
So, we have
(7x³ - 13x² - 23x - 5)/(x-3)
Set the divisor to 0
x - 3 = 0
So, we have
x = 3
Using a synthetic setup, we have

The synthetic division is then carried out as follows
3 | 7 - 13 - 23 - 5

Answer:
X = 37.8
Step-by-step explanation:

Making that proportion, you get;

SlopeThe equation for the slope between two points is ...

Write and solve an equation to determine the measure of angle x. (5 points)
Your answer:
Answers
The equation x + (60 + 70)° = 180° is used to solve for the measure of the vertical angle x = 50°
What are vertically opposite anglesVertical angles also called vertically opposite angles are formed when two lines intersect each other, the opposite angles formed by these lines are vertically opposite angles and are equal to each other.
The angle y and x form vertical angles, so x = y
Angle y form a straight line with 60° and 70° so we have the equation to solve for x as:
x + 60° + 70° = 180° {sum of angles on a straight line}
x + 130° = 180°
x = 180° - 130° {subtract 139° from both sides}
x = 50°
Therefore, the measure of the vertical angle x is equal to 50° derived with the equation x + (60° + 70°) = 180°.

Jessica's speed is 4 mph and Janine's speed is 8 mph
Let us assume that x represents Jessica's speed.
Janine bikes 4 mph faster than her sister, Jessica.
So, Janine's speed would be (x + 4) mph
We know that the formula for the speed is: speed = distance/time
Here, Janine can ride 24 mi in 3 hr less time than Jessica can ride the same distance.
24/(x+4) = (24/x) - 3
24/(x+4) = (24 - 3x)/x
24x = (24 - 3x)(x + 4)
24x = 24x + 96 - 3x² - 12x

Step-by-step explanation:
A straight line passes through the points (3, k) and (-3, 2k). If the gradient of the line is -⅔. find the value of k. What is the equation of this line?
Answers
Answer:
To find the value of k and the equation of the line, we can use the slope-intercept form of a line: y = mx + b, where m is the slope of the line, and b is the y-intercept.
The slope of the line (m) is given as -⅔. To find the y-intercept (b), we can substitute one of the given points and the value of m into the equation.
Let's use the point (3,k) :
y = mx + b
k = -⅔ * 3 + b
k = -2 + b
b = k + 2
Now we have the equation of the line in the slope-intercept form: y = -⅔x + (k + 2)
To find the value of k we can use the other point (-3, 2k) and substitute into the equation:
2k = -⅔(-3) + (k + 2)
2k = 2 + k + 2
k = -2
So the value of k is -2 and the equation of the line is y = -⅔x + (k + 2) = -⅔x - 2
This line is a straight line with the slope of -⅔ which passes through the points (3, k) and (-3, 2k) and its equation is y = -⅔x - 2
