select answers from the drop-down menus to correctly complete the statements.
the eccentricity of the ellipse is approximately
. this value indicates that the ellipse is more
The value e = 0.869 indicates that the ellipse is more elongated that circular.
Given,
x²/12+y²/49 = 1
We will compare with x²/a² + y²/b² = 1 where a<b
Coordinate of center = (0,0)
Here a²=12 and b²=49
We know that the formula of eccentricity(e)
e=√(1-(a²/b²))
= √(1-(12/49))
= √37/7
=0.869
Therefore e=√37/7 = 0.869
Therefore this value indicates that the ellipse is more elongated that circular.
In mathematics, an ellipse is a plane bend encompassing two central focuses, to such an extent that for all focuses on the bend, the amount of the two distances to the central focuses is a consistent. It sums up a circle, which is the extraordinary kind of oval wherein the two focal points are something similar.

The confidence interval is (233.8436; 271.0564).
What is a confidence interval?
The likelihood that a population parameter will fall between a set of values for a specific percentage of the time is referred to as the confidence interval. Confidence ranges that include 95% or 99% of anticipated observations are frequently used by analysts.
What is the margin of error?
In a random survey sample, a margin of error is a statistical measurement that takes into account the discrepancy between actual and anticipated findings.
We have,
Sample mean = 252.45
Sample standard deviation = 74.50
n = 64
α = 0.05
By applying the margin of error formula, we get
Margin of Error = tα/2 * s/√n
df = n - 1 = 64 - 1 = 63
t(α/2, df = 63) = 1.998
Margin of Error = 1.998 * 74.50/√64
Margin of Error = 18.6064
The confidence interval = 252.45 ± 18.6064
= (233.8436; 271.0564)

Probability that the sample mean rent is less than $2,918.03 is 0.050154
We are given that the Real Estate Group NY reports that the mean monthly rent for a one-bedroom apartment without a doorman in Manhattan is $2886. Assume the standard deviation is $586.
Also, a real estate firm samples 94 apartments.
Let X = sample mean rent
The sample mean's z-score probability distribution is provided by;
Z = X-u/σ/[tex]\sqrt{n}[/tex] ~ N(0,1)
where, u= population mean monthly rent = $2,886
σ = standard deviation = $586
n = sample of apartments = 94
Now, the probability that the sample mean rent is less than $2,918.03 is given by = P( < $2,918.03)
P( < $2,918.03) = P(Z < 0.52)= 0.050154
The above probability is calculated using z table by looking at value of x = 0.52 in the z table which have an area of 0.050154

Two cyclists are 7 miles apart when they begin biking away from each other in
opposite directions. The speed of the first cyclist is 12 miles
per hour. The speed of
the second cyclist is b miles per hour greater than the speed of the first cyclist.
How many
miles does the second cyclist bike in 45 minutes?
The distance covered by second cyclist is, 9 + (3/4)b miles.
What is speed?
Speed is calculated as follows: speed = distance * time. Knowing the units for distance and time is necessary to calculate the units for speed. The units will be meters per second (m/s) in this example since the distance is measured in meters (m) and the time is measured in seconds (s).
Given: Two cyclists are 7 miles apart when they begin biking away from each other in opposite directions.
The speed of the first cyclist is 12 miles per hour. The speed of the second cyclist is b miles per hour greater than the speed of the first cyclist.
Speed of first cyclist = 12 miles per hour.
Speed of second cyclist = 12 + b miles per hour.
Since, distance = speed x time
The distance covered by the second cyclist in 45 minutes is,
45 minutes = 45/60 = 3/4 hour.
Therefore, distance covered by second cyclist is,
= (12 + b) x 3/4 = 9 + 3b/4 miles.

One-half < Three-fourths < Two-thirds
One-half < Two-thirds < Three-fourths
Two-thirds < One-half < Three-fourths
Three-fourths < One-half < Two-thirds
An inequality correctly compares One-half, Three-fourths, and Two-thirds is: One-half < Two-thirds < Three-fourths.
What is an inequality?An inequality simply refers to a mathematical relation that can be used to compare two (2) or more numerical values (numbers) and variables in an algebraic equation, especially based on any of the following inequality symbols:
Greater than (>).Less than (<).Greater than or equal to (≥).Less than or equal to (≤).Translating the numbers in word to numerical values, we have:
One-half = 1/2 or 0.5
Three-fourths = 3/4 or 0.75
Two-thirds = 2/3 or 0.67
Next, we would compare the above numerical values by using the less than (<) inequality symbol as follows:
0.5 < 0.67 < 0.75
One-half < Two-thirds < Three-fourths.

Question 6
After simplification, the second option |−4| < |−5| is true.
In the given question,
There are four options. We have to check which option is true.
The given options are
1) |−5| < 4
2) |−4| < |−5|
3) |−5| = −5
4) |−4| > |5|
To find the true option we solve the given option one by one.
The first option is
|−5| < 4
Now solving
As we know that every value from the mod always give positive value.
So if we solve |−5| then the value is 5 and 5 is greater than 4. But in the given statement states that 4 is greater that 5. So the first statement is wrong.
Now solving the second statement.
|−4| < |−5|
After solving |−4|, the value is 4 and |−5| is 5.
So the simplified statement is 4 < 5 which is true.
Hence, the second statement is true.
Now we get the true statement so we haven't solve any further option.
If you want the solve next option the the way of solving the option is same.

How to find the measure of angles in a triangle?A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.
The triangle has the sum of the measures of the angles as 180°.
Angle A is three times as large as angle B and also 16° larger than C.
Therefore,
let
angle A = x
Angle B = x / 3
Angle C = x - 16
Therefore,
x + x - 16 + x /3 = 180
7 / 3 x - 16 = 180
7 / 3 x = 180 + 16
7 / 3 x = 196
cross multiply
7x = 196 × 3
7x = 588
divide both sides by 7
x = 588 / 7

Given the equation x² + y² + 4x - 8y + 11 = 0, the center of the circle is (-2, 4).
The standard form of the equation of circle is given by
(x - h)² + (y - k)² = r²
where (h , k) is the location of the center and r is the radius of the circle.
On the other hand, the general form of the equation of circle is given by
x² + y² + Dx + Ey + F = 0
where D = -2h, E = -2k, and F = h² + k² - r².
If the equation of the circle in general form is x² + y² + 4x - 8y + 11 = 0, then the coefficients are:
D = 4
E = -8
F = 11
If D = -2h and D = 4, then

How to calculate AGI(Adjusted gross income) ?
The AGI calculation can be done as,
It is determined by subtracting specified deductions, or "adjustments," that you are qualified to claim from the total income you report that is subject to income tax, such as wages from a job or self-employment, dividends, and interest from a bank account.Before you take the standard or itemized deductions, which you record in later sections of your tax return, your AGI is computed.We have given that,
Gross income = $23670
1 Exemption = $12400
Adjustment = 0
Deduction = 0
Find AGI and Taxable income
AGI = Adjusted gross income
we know,
AGI = Total income - Any deduction or any adjustment
AGI = ($23,670 + $12400) - (0 + 0)
AGI = $36070
Now, Calculate taxable income
Taxable income = Gross income - 1 Exemption
= $23670 - $12400
