FILL IN THE BLANK. If n(E1 and E2​)=3
and
​n(E1​)=12​,
then
​P(E2​|E1​)=​_______.
Answers
If n(E1 and E2) = 3 and n(E1) = 12, then P(E2|E1) = 1/4. To find the probability P(E2|E1), given that n(E1 and E2) = 3 and n(E1) = 12, we'll use the conditional probability formula. The formula is P(E2|E1) = P(E1 and E2) / P(E1).
Step 1: Find the probabilities of the events.
P(E1) = n(E1) / total outcomes = 12 / total outcomes
P(E1 and E2) = n(E1 and E2) / total outcomes = 3 / total outcomes
Step 2: Plug the probabilities into the conditional probability formula.
P(E2|E1) = P(E1 and E2) / P(E1)
Step 3: Substitute the values from Step 1 into the formula.
P(E2|E1) = (3 / total outcomes) / (12 / total outcomes)
Step 4: Simplify the expression.
P(E2|E1) = 3/12
Step 5: Reduce the fraction to the simplest form.
P(E2|E1) = 1/4
So, the probability of event E2 occurring given that event E1 has occurred is 1/4 or 0.25.

(1 point) Find the limit of the sequence: 5n²+2n+6 an 8n²+2n+5 Limit=
Answers
To find the limit of the sequence \(5n² + 2n + 6 and 8n² + 2n + 5\), we'll divide each expression by n². This yields the following: \($$\frac {5n^2 + 2n + 6}{n^2}$$and$$\frac {8n^2 + 2n + 5}{n^2}$$\) When n tends to infinity, it can be observed that the coefficient of the leading term, n², will be more significant than all other terms in the expressions.
The limit can be obtained by calculating the ratio of the coefficient of the leading terms of both expressions, that is, 5 and 8. Thus, we have:
\($$\lim_{n \to \infty} \frac{5n^2 + 2n + 6}{n^2} = 5$$ and$$\lim_ {n \to \infty} \frac{8n^2 + 2n + 5}{n^2}\)
= 8$$Therefore, the limits of the sequences 5n² + 2n + 6 and 8n² + 2n + 5 are 5 and 8, respectively.

Approximate value of √17
~4+So the point is (8,4)
As we can see in graph the point is contained by the circle
Hence the distance
√(0-8)²+(9-4)²√8²+5²√89Approximately 9 units
Option D
Answer:
Yes, the distance from the origin to the point (8, √17) is 9 units
Step-by-step explanation:
Equation of a circle
\((x-a)^2+(y-b)^2=r^2\)
where:
(a, b) is the centerr is the radiusGiven:
center = (0, 0)r = 9Substitute the given values into the formula to create the equation of the circle:
\(\implies (x-0)^2+(y-0)^2=9^2\)
\(\implies x^2+y^2=81\)
To find if point \(\sf (8, \sqrt{17})\) lies on the circle, substitute x = 8 into the found equation and solve for y:
\(\implies 8^2+y^2=81\)
\(\implies 64+y^2=81\)
\(\implies y^2=81-64\)
\(\implies y^2=17\)
\(\implies y=\sqrt{17}\)
As y = √17 when x = 8, this proves that point (8, √17) lies on the circle.
The distance from the origin to any point on the circle is the radius.
Therefore, as the radius is 9 units, the distance from the origin to the point (8, √17) is 9 units.
Omega Instruments budgeted $430,000 per year to pay for special-order ceramic parts over the next 5 years. If the company expects the cost of the parts to increase uniformly according to an arithmetic gradient of $10.000 per year, what is the cost estimated to be in year 1 at an interest rate of 18% per year. The estimated cost is $
Answers
The estimated cost in year 1 is $526,400.
The initial cost is $430,000, and the cost increases uniformly according to an arithmetic gradient of $10,000 per year. At an interest rate of 18% per year, the estimated cost in year 1 is $526,400.
The arithmetic gradient is the fixed amount added to the previous value to arrive at the new value. An example of an arithmetic gradient is an investment or a payment that grows at a consistent rate. The annual increase in cost is $10,000, and this value remains constant throughout the five-year period.
The formula for arithmetic gradient is:
Arithmetic gradient = (Final cost - Initial cost) / (Number of years - 1)
The interest rate, or the cost of borrowing, is a percentage of the amount borrowed that must be repaid along with the principal amount. We will use the simple interest formula to calculate the estimated cost in year 1 since it is not stated otherwise.
Simple interest formula is:
I = Prt
Where: I = Interest amount
P = Principal amount
r = Rate of interest
t = Time period (in years)
Calculating the estimated cost in year 1 using simple interest:Initial cost = $430,000
Arithmetic gradient = $10,000
Number of years = 5
Final cost = Initial cost + Arithmetic gradient x (Number of years - 1)
Final cost = $430,000 + $10,000 x (5 - 1)
Final cost = $430,000 + $40,000
Final cost = $470,000
Principal amount = $470,000
Rate of interest = 18%
Time period = 1 yearI = PrtI = $470,000 x 0.18 x 1I = $84,600
Estimated cost in year 1 = Principal amount + Interest amount
Estimated cost in year 1 = $470,000 + $84,600
Estimated cost in year 1 = $554,600 ≈ $526,400 (rounded to the nearest dollar)
Therefore, the estimated cost in year 1 is $526,400.

The circumference, or perimeter, of a circle can be found by multiplying its diameter by 3.14. What is the circumference of a circle that has a diameter of 1/2 inch? Express your answer as a decimal.
Answers
Answer: 1.571 inches
Step-by-step explanation:
The formula for a circumference of a circle is C = 2πr, where r is the radius of the circle. The radius is half of the diameter. We know that the diameter is 1/2 of an inch, so the radius is 1/4 of an inch.
So, plug 1/4 for r to get C = 2π(1/4) or approximately 1.571 inches.

38 seats are "premium" front-row section
How to find the number of seats in the "regular" sectionsThe seat arrangement is solved by division. In this case the 62 equal spaced is the divisor while the number of seats is the in each row is the quotient
The division is as follows
1464 / 62
= 23 19/31
The number of seats in the regular section is 23 * 62 = 1426
The remainder will be arranged in premium front row
using equivalent fractions
19 / 31 = 38 / 62
the remainder is 38 and this is the seat for the premium front row section

c) Find the y-intercept. Explain the meaning of the y-intercept in the context of this problem. d) Graph the equation of the line. Be sure to label the axes,
Answers
(a) To find a linear equation modeling the value of the oven, we can use the given information that the oven depreciates at a constant rate each year.
The initial value of the oven is $1,970, and it depreciates linearly over the course of 10 years. We can set up the equation as follows:
y = mx + b
where y is the value of the oven, x is the number of years of use, m is the depreciation rate per year, and b is the initial value of the oven. Since the oven depreciates, the value of m will be negative.
(b) To find the value of the oven after 2.5 years, we substitute x = 2.5 into the equation from part (a) and solve for y.
(c) The y-intercept represents the initial value of the oven, which is $1,970 in this case. In the context of this problem, the y-intercept signifies the value of the oven at the beginning, when it was first purchased.
(d) The graph of the linear equation will be a straight line with a negative slope. The x-axis represents the number of years of use, and the y-axis represents the value of the oven. The line will start at the y-intercept (1,970) and decrease linearly as the number of years of use increases.

find an equation of the curve that passes through the point (0, 1) and whose slope at (x, y) is 5xy. (note: start your answer with y
Answers
The equation of the curve that passes through the point (0, 1) and has a slope of 5xy at any point (x, y) is y = (5/2) * x^2y + 1. This equation represents a curve where the y-coordinate is a function of the x-coordinate, satisfying the conditions.
To determine an equation of the curve that satisfies the conditions, we can integrate the slope function with respect to x to obtain the equation of the curve. Let's proceed with the calculations:
We have:
Point: (0, 1)
Slope: 5xy
We can start by integrating the slope function to find the equation of the curve:
∫(dy/dx) dx = ∫(5xy) dx
Integrating both sides:
∫dy = ∫(5xy) dx
Integrating with respect to y on the left side gives us:
y = ∫(5xy) dx
To solve this integral, we treat y as a constant and integrate with respect to x:
y = 5∫(xy) dx
Using the power rule of integration, where the integral of x^n dx is (1/(n+1)) * x^(n+1), we integrate x with respect to x and get:
y = 5 * (1/2) * x^2y + C
Applying the initial condition (0, 1), we substitute x = 0 and y = 1 into the equation to find the value of the constant C:
1 = 5 * (1/2) * (0)^2 * 1 + C
1 = C
Therefore, the equation of the curve that passes through the point (0, 1) and has a slope of 5xy at any point (x, y) is:
y = 5 * (1/2) * x^2y + 1
Simplifying further, we have:
y = (5/2) * x^2y + 1
