Answers
The equation of an ellipse with center, (h, k) that is elongated in the x-direction is: (x - h)²/a² + (y - k)²/b² = 1.
What is defined as the ellipse?In aspects of locus, an ellipse is the collection of every point on an XY-plane with whom the distance from 2 fixed points (called foci) adds up to the a constant value.
Ellipse does have two focal points, which are also known as foci.A fixed distance is referred to as a directrix.The eccentricity of an ellipse ranges from 0 to 1.The total sum of every distance from an ellipse's locus to its two focal points is constant.Ellipse contains a single major and one minor axis, as well as a center.The standard form of equation of ellipse with centres (h, k) that is elongated in the x-direction is given as;
(x - h)²/a² + (y - k)²/b² = 1
Now, when the centre of the ellipse coincides with the origin of coordinates axis, the becomes;
x²/a² + y²/b² = 1

What is the value of x in the given equation?Given the data in the question;
( 7x + 6 )/4 = ( 2x − 3 )/5x = ?To solve for x, first we cross multiply
( 7x + 6 )/4 = ( 2x − 3 )/5
5( 7x + 6 ) = 4( 2x − 3 )
Remove the parenthesis using distributive property
7x×5 + 6×5 = 2x×4 − 3×4
35x + 30 = 8x - 12
Collect like terms by moving all terms containing x to the left and all constant terms to the right side of the equation.
35x - 8x = -12 - 30
27x = -12 - 30
27x = -42
Divide both sides by 27

Answers
Answer:
The constant of proportionality is $1.80
y = 1.80x
Step-by-step explanation:
The constant of proportionality is $1.80
An equation that relates the total cost, y, and the number of lemons, x, is
y = 1.80x
where,
y =Total cost
x = number of lemon
When x = 4
y = 1.80x
y = 1.80(4)
y = 7.2
y = $7.2
When y = $4.20
y = 1.80x
4.20 = 1.80x
x = 4.20 / 1.80
x = 2 1/3
x = 2 1/3
When y = $9.00
y = 1.80x
9.00 = 1.80x
x = 9.00 / 1.80
x = 5
x = 5
When x = 18
y = 1.80x
y = 1.80 × 18
y = 32.4
y = $32.4

How to find how long would it take Stacy and Diego to paint the doghouse while working alonegiven data
Diego and Stacy can paint a doghouse in 5 hours
Diego works twice as fast as Stacy
Let x be the number of hours it would take Diego to paint the doghouse and y be the number
Putting the given information mathematically
Diego and Stacy can paint a doghouse in 5 hours
x + y = 5hoursDiego works twice as fast as Stacy
x = 2yx + y = 5hours
Since x = 2y
2y + y = 5
3y = 5
y = 5/3
y = 1 1/3
from x = 2y
x = 2 * 5/3
x = 10/3
x = 3 1/3
1/3 hours is a fraction of hours. we convert it to minutes by multiplying by 60
= 1/3 * 60
= 20 minutes
Therefore it will take Diego 3 hours 20 minutes and Stacy 1 hour 20 minutes for them to complete a 5 hours work
If Diego works alone
Diego alone = 5 hours + Stacy's hours * 1/2
since Diego is twice faster than Stacy then Stacy's time will be halved
Diego alone = 5 hours + 80 minutes * 1/2
Diego alone = 5 hours + 40 minutes
Diego alone = 5 hours 40 minutes
if Stacy works alone
Stacy alone = 5 hours + Diego's hours * 2
Stacy alone = 5 hours + 3 hours 20 minutes * 2
Stacy alone = 5 hours + 6 hours 40 minutes
Stacy alone = 11 hours 40 minutes

assume that the traffic to the web site of smiley’s people, inc., which sells customized t-shirts, follows a normal distribution, with a mean of 4.56 million visitors per day and a standard deviation of 720,000 visitors per day. (a) what is the probability that the web site has fewer than 5 million visitors in a single day? if needed, round your answer to four decimal digits
Answers
The probability that the web site has fewer than 5 million visitors in a single day is 0.7293.
For a normally distributed set of data, given the mean and standard deviation, the probability can be determined by solving the z-score and using the z-table.
First, solve for the z-score using the formula below.
z-score = (x – μ) / σ
where x = individual data value = 5 million
μ = mean = 4.56 million
σ = standard deviation = 720,000
z-score = (5 million - 4.56 million) / 720,000
z-score = 440,000 / 720,000
z-score = 0.6111
Find the probability that corresponds to the z-score in the z-table. (see attached images)
z-score = 0.6111

probability = 0.7293

N(0.97,0.001) distribution. The specifications allow slot widths between 0.9698
0.9698 and 0.9702
What proportion of slots meet these specifications?
Answers
The proportion of slots who meet these specifications is 15.86%.
We are given that the width in inches of slots cut by a milling machine follows approximately the N(0.97,0.001) distribution.
Also, the specifications allow slot widths between 0.9698 and 0.9702
Let X = width in inches of slots cut by a milling machine
The z-score probability distribution for normal distribution is given by;
Z = (X - μ) /σ ~ N(0,1)
where, μ = population mean width = 0.97
σ = standard deviation = 0.001
The Z-score measures how many standard deviations the measure is away from the mean. After finding the Z-score, we look at the z-score table and find the p-value (area) associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X.
Now, Probability that the specifications allow slot widths between 0.9698 and 0.9702 is given by = P(0.9698 < X < 0.9702)
= P(0.9698 < X < 0.9702) = P(X < 0.9702) - P(X 0.9698)
P(X < 0.9702) = P [(X - μ) /σ < [tex]\frac{0.9702 - 0.97}{0.001}[/tex]] = P (Z < 0.2) =
P(X ≤0.9698) = P [(X - μ) /σ ≤ [tex]\frac{0.9698 - 0.97}{0.001}[/tex] ] = P (Z ≤ -0.2) = 1- P(Z < 0.2)
= 1 - 5793 = 0.4207
So, in the z table the P(Z x) or P(Z < x) is given. So, the above probability is calculated by looking at the value of x = 0.2 in the z table which has an area of 0.5793.
Therefore, P(0.9698 < X < 0.9702) = 0.5793 - 0.4207 = 0.1586
Hence, the proportion of slots who meet these specifications is 15.86%.

Answers
The correct statement about the triangle's image and pre-image is 'the image and pre-image are not congruent because one of the transformation is rigid transformation and the other is not.'
The correct answer is an option (1)
In this question, a triangle is dilated by a factor of 2 and then rotated clockwise.
We need to select the correct statement about the triangle's image and pre-image.
We know that rotation is a rigid transformation but dilation is not a rigid transformation.
Dilation does not preserve the size of the image.
Also, the image and pre-image are not congruent as the corresponding sides of triangle's image and pre-image are not equal.
Therefore, the correct statement about the triangle's image and pre-image is 'the image and pre-image are not congruent because one of the transformation is rigid transformation and the other is not.'

The value of c in the equation cx+4y=12 would give the equation a slope of 8 would be 32.
What is the slope of a straight line?A straight line of the form y = MX + c has its slope as 'm'
It is constant for a line. The more the slope is, the steeper the line is.
Sign convention takes bottom left to top right going line as positive sloped. And that line which goes from bottom right to top left is taken to have a negative slope. The horizontal line has 0 slopes and the vertical line has an infinite slope, as it is now at maximum steepness.
We have been given the equation cx+4y=12 which has a slope of 8.
Also cx+4y=12
4y = 12 - cx
y = 12/4 - cx/4
y = 3 - cx/4
Then we know that straight line of the form y = mx + c
By comparing the formula;
y = 3 - cx/4
Slope = c/4 = 8
c/4 = 8
c = 8(4)
c = 32
Therefore, the value of c in the equation cx+4y=12 would give the equation a slope of 8 would be 32.
