a. Write an equation in slope intercept form that gives the total amount Laura has in her savings account after x months
b. How many months has Laura been putting money into the account? Explain your answer.
C. Laura's brother also opened a savings account with $200, but his monthly deposit is not the same as Laura's Describe the similarities and differences between the equation and graph describing the amount of money in Laura's account and the equation and graph describing the amount of money in her brother's account
Answers
Answer:
Laura has been adding $50 to her savings every month which means the equation would be 200 + 50 for each month that she has been adding to her saving account, Laura has been putting money in her saving for nine months since each month shes adding $50, The similiarties are that they both opened an account with $200 but the differences is that Laura has been adding $50 and Lauras brother has been adding a different amount as Laura.

after months of negotiations,jabus annual salary was increased by 6,5percent to R330 000. determine his previous monthly salary and the monthly increase he will be getting
Answers
Answer:
previous monthly salary is R 308,550 and increment is R 21,450
Step-by-step explanation:
Let the previous monthly salary be x
Current salary = R 330,000
Percent increase = 6,5%
Increase = 6.5% * 330,000
Increase = 0.065 * 330,000
Increase = Rs21,450
Previous salary = 330,000 - 21,450
Previous salary = 308,550
Hence previous monthly salary is R 308,550 and increment is R 21,450

Among the most famous of all meteor showers are the Perseids, which occur each year in early August. In some areas the frequency of visible Perseids can be as high as 40 per hour. What is the probability that an observer who has just seen a meteor will have to wait at least 5 minutes before seen another.
Answers
Answer:
the required probability is 0.0357
Step-by-step explanation:
Given the data in the question;
X-Exp( λ = 40/60 = 0.6667
Pdf: f( x ) = λe^(-λx), 0 < x
so
Cdf: P( X < x ) = 1 - e^(-λe)
( X ≤ x ) = 1 - e^(-λe), for x > 0 ⇒ p( X > x ) = e^(-λe)
now to wait at least 5 minutes before seen another
p(X > 5 ) = e^(-λe)
we substitute
p(X > 5 ) = e^(-0.6667 × 5)
p(X > 5 ) = e^(-3.3335)
p(X > 5 ) = 0.035668 ≈ 0.0357
Therefore, the required probability is 0.0357

Which box plot correctly displays the data set with a maximum of 48, a minimum of 27, a median of 36, an upper quartile of 45, and a lower quartile of 32?
(please refer to the answer like this: Image [number])
Answers
Answer:
Image 1
Step-by-step explanation:
To answer this question, we need to know how to use a box plot.
I've attached an image that demonstrates this well and can teach you what each part of the box plot means.
Specifically, the 2 farthest dots at the end are the minimum and maximum. The two sides where the box starts are the lower and upper quartiles. Finally, the line in the middle of the box is the median.
With this, we can analyze each box plot and determine which one is correct.
Box Plot 1: Everything is plotted correctly- Maximum and minimum plotted correctly, median plotted correctly, upper and lower quartile plotted correctly.
Box Plot 2: Everything plotted correctly EXCEPT maximum of 48 is represented at 46.
Box Plot 3: Everything plotted correctly EXCEPT the upper quartile of 45 is at 39.
Box Plot 4: Upper quartile represented at 39 and maximum represented at 46 are both incorrect.

Answers
Answer:
a-1. The predicted price of a house with ocean views and square footage of 2,000 is $411,500.00.
a-2. The predicted price of a house with ocean views and square footage of 3,000 is $531,500.00.
b-1. The predicted price (in $1,000s) of a house without ocean views and square footage of 2,000 is $358,900.
b-2. The predicted price of a house without ocean views and square footage of 3,000 is $478,900.00.
c. The correct option is An ocean view increases the value of a house by approximately $52,600.
Step-by-step explanation:
Given:
yˆ = 118.90 + 0.12x + 52.60d ………………. (1)
a-1. Compute the predicted price (in $1,000s) of a house with ocean views and square footage of 2,000. (Round intermediate calculations to at least 4 decimal places. Round your answer to 2 decimal places.)
This implies that we have:
x = 2,000
d = 1
Substituting the values into equation (1), we have:
yˆ = 118.90 + (0.12 * 2000) + (52.60 * 1) = 411.50
Since the predicted price is in $1,000s, we have:
yˆ = 411.50 * $1000
yˆ = $411,500.00
Therefore, the predicted price of a house with ocean views and square footage of 2,000 is $411,500.00.
a-2. Compute the predicted price (in $1,000s) of a house with ocean views and square footage of 3,000. (Round intermediate calculations to at least 4 decimal places. Round your answer to 2 decimal places.)
This implies that we have:
x = 3,000
d = 1
Substituting the values into equation (1), we have:
yˆ = 118.90 + (0.12 * 3,000) + (52.60 * 1) = 531.50
Since the predicted price is in $1,000s, we have:
yˆ = 531.50 * $1000
yˆ = $531,500.00
Therefore, the predicted price of a house with ocean views and square footage of 3,000 is $531,500.00.
b-1. Compute the predicted price (in $1,000s) of a house without ocean views and square footage of 2,000. (Round intermediate calculations to at least 4 decimal places. Round your answer to 2 decimal places.)
This implies that we have:
x = 2,000
d = 0
Substituting the values into equation (1), we have:
yˆ = 118.90 + (0.12 * 2000) + (52.60 * 0) = 358.90
Since the predicted price is in $1,000s, we have:
yˆ = 358.90 * $1000
yˆ = $358,900.00
Therefore, the predicted price of a house without ocean views and square footage of 2,000 is $358,900.00.
b-2. Compute the predicted price (in $1,000s) of a house without ocean views and square footage of 3,000. (Round intermediate calculations to at least 4 decimal places. Round your answer to 2 decimal places.)
This implies that we have:
x = 3,000
d = 0
Substituting the values into equation (1), we have:
yˆ = 118.90 + (0.12 * 3,000) + (52.60 * 0) = 478.90
Since the predicted price is in $1,000s, we have:
yˆ = 478.90 * $1000
yˆ = $478,900.00
Therefore, the predicted price of a house without ocean views and square footage of 3,000 is $478,900.00.
c. Discuss the impact of ocean views on the house price.
Since the coefficient of d in equation (1) is 52.60 and positive, and the predicted price is in $1,000s; the correct option is An ocean view increases the value of a house by approximately $52,600.

Answer:
(x +6)^2 +(y -10)^2 = 225
Step-by-step explanation:
The standard form equation for a circle is ...
(x -h)^2 + (y -k)^2 = r^2
where the center is (h, k) and the radius is r.
The center of a circle is the midpoint of any diameter. The midpoint between two points is the average of their coordinates.
((-15, -2) +(3, 22))/2 = (-15+3, -2+22)/2 = (-6, 10)
The radius can be found using the distance formula, or by simply putting one of the given points in the equation for the circle to see what the constant (r^2) needs to be.
(x -(-6))^2 +(y -10)^2 = (-15-(-6))^2 +(-2-10)^2
(x +6)^2 +(y -10)^2 = 81 +144 = 225
The equation of the circle is ...
(x +6)^2 +(y -10)^2 = 225
