Answer:
y = (-3x/5) +1
Step-by-step explanation:
We know that the line passes through the point (-5 , 4)
AND
the slope is given to be -3/5
let's look at the slope a bit more
we know that the formula for slope of a line is Rise / Run
Which means that the rise of this line is -3 after spanning 5 units to the right
Hence, the line goes down 3 units after moving 5 units to the right
We know that to find the equation of a line through the point-slope equation, we need the slope as well as the y-intercept of the line
since we are already given the slope, we need to find the point where the line intersects the y-axis
Now, back to the given point the line passes through
this point has a x - coordinate of -5 and we know that after moving 5 units to the right, the line moves 3 units downwards
So, if the line moves 5 units to the right from the given point, it will reach the y- axis and we know that it's y-coordinate will decrease by 3
Hence, the y-intercept will be 3 units below the given y -coordinate
y - intercept = (4 - 3) = 1 = y-intercept
Now, using the slope-intercept formula to get the equation:
y = (slope)*x + (y-intercept )
y = (-3/5)x + (1)
y = (-3x/5) + 1

A landlord is considering upgrades and repairs, including wood floors, kitchen tile, a new back door, and a repaired garage door. The landlord could do these things himself or hire a contractor. The contractor could finish the job in half the time but would charge more. The landlord wants to leave the choice of whether to actually upgrade the kitchen tile up to the optimization algorithm. How should this constraint be written if he uses the following scheme for decision variables? x1 = contractor works on wood floors x2 = landlord works on wood floors x3 = contractor works on kitchen tile x4 = landlord works on kitchen tile x5 = contractor works on back door x6 = landlord works on back door x7 = contractor works on garage door x8 = landlord works on garage door Group of answer choices x3+ x4≤ 1 x3+ x4= 1 x3- x4= 1 x3- x4≤ 1
Answers
Answer:
x3 + x4 ≤ 1
Step-by-step explanation:
Upgrades considered = wood floors, Kitchen tile, New back door and a repaired garage
The constraint of whether to upgrade the kitchen either by the landlord or by a contractor can be represented with the scheme below:
x3 + x4 ≤ 1
The constraint is written this way because only one scheme can be used at a time i.e when x3 = 1 , x4 = 0 and vice versa. also
note that both x3 and x4 can be = 0. because the upgrade of the kitchen tiles is under probability and the landlord might decide not to upgrade the kitchen tiles hence both schemes ( x3 and x4 ) can be = 0

Assume you have applied for two scholarships, a Merit scholarship (M) and an Athletic scholarship (A). The probability that you receive an Athletic scholarship is 0.18. The probability of receiving both scholarships is 0.11. The probability of getting at least one of the scholarships is 0.3. Let M denote the event that you will receive a Merit scholarship. Let A denote the event that you will receive an Athletic scholarship. Answer questions 11-15. What is the probability that you will receive a Merit scholarship
Answers
Answer:
The probability of obtaining a Merit Scholarship = 0.23
Step-by-step explanation:
From the given information:
The probability of obtaining a merit scholarship P(A) = 0.18
The probability of obtaining both P(A ∩ M) = 0.11
The probability of getting at least one P(A ∪ M) = 0.3
The objective is to determine the probability of obtaining a Merit Scholarship.
So, as given:
if M represents Merit Scholarship and A represent Athletic Scholarship,
the probability of obtaining a Merit Scholarship is as follows;
P(M) = P(A ∪ M) + P(A ∩ M) - P(A)
P(M) = 0.3 + 0.11 - 0.18 = 0.23
P(M) = 0.23

Triangle A to B has a change of +2 in y values, Triangle B to C has a change of +4 values so each triangle doesn’t have same change in values.
Triangle A to B change in y over change in x = 2/3, Triangle B to C change in y over change in x = 4/6, both have decimal values of 0.66. Therefore, each triangles has the same ratio of change in y over change in x.

A market researcher collects a simple random sample of customers from a population of over a million customers that use a home improvement website. After analyzing the sample, she states that she has 95% confidence that the mean time customers spent on that website per day is between and minutes. Suppose that the population mean time customers spent on that website is minutes a day. Does this value of the population mean help to show that the confidence interval estimate is correct? Explain.
Answers
Answer:
No, because the population mean, μ, is not included within the confidence interval estimate.
Step-by-step explanation:
A (1 - α)% confidence interval for a population parameter can be used make inferences about a statistic test of the parameter.
Decision rule:
If the null value of the population parameter is included in the interval then the null hypothesis will not be rejected. And vice-versa.
In this case, a market researcher wants to determine whether the population mean time customers spent on that website is 13 minutes a day or not.
The hypothesis can be defined as follows:
H₀: The population mean time customers spent on that website is 13 minutes a day, i.e. μ = 13.
Hₐ: The population mean time customers spent on that website is different from 13 minutes a day, i.e. μ ≠ 13.
The 95% confidence interval that the mean time customers spent on that website per day is, (15, 50).
The 95% confidence interval for the population mean time does no consist of the null value. Thus, the null hypothesis will be rejected.
It can be concluded that the population mean time customers spent on that website is not 13 minutes. Since the 95% confidence interval consist of values more than 13 minutes, it can be said that the mean time customers spent on that website is more than 13 minutes.
Thus, the answer is:
No, because the population mean, μ, is not included within the confidence interval estimate.

Anna takes 10 selfies every 12 minutes at this rate how many minutes for 25 selfie’s
Answers
Answer:
30 minutes.
Step-by-step explanation:
You can make a proportion, which would be 10 selfies : 12 minutes. The second one will be 25 selfies : x minutes.
They have to be equal, since it is given that the rate stays the same. So 10:12=25:x
A proportion can be written as a fraction, so 10/12=25/x.
Cross multiply, and you get 10*x=12*25, or 10x=300.
Now divide both sides by 10 to get x=30.
2) Why is it that when you fill the venn diagram with the number of elements, you
always need to start from the intersection of all sets?
Answers
Answer:
This is because it is easier this way.
You avoid the problem of putting an element in one set and then realizing that the element also belongs to another set, then you must erase something in order to put the element in both sets. Starting with the intersection allows you to know where will be each set in the diagram, and in this way, the diagram should end up being more readable or "clean".
This may seem small, but being "clean" when doing math, will allow you to have an easier time dealing with a lot of problems. And also will be easier for other people when reading your equations and such.

a. Draw a histogram of the binomial distribution for the survey.
b. What is the most likely outcome of the survey?
c. What is the probability that at least 3 families have a family dinner four times per week?
Answers
Step-by-step explanation:
Use binomial probability:
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
Given n = 5, p = 0.58, and q = 0.42.
P(0) = ₅C₀ (0.58)⁰ (0.42)⁵⁻⁰ = 0.013
P(1) = ₅C₁ (0.58)¹ (0.42)⁵⁻¹ = 0.090
P(2) = ₅C₂ (0.58)² (0.42)⁵⁻² = 0.249
P(3) = ₅C₃ (0.58)³ (0.42)⁵⁻³ = 0.344
P(4) = ₅C₄ (0.58)⁴ (0.42)⁵⁻⁴ = 0.238
P(5) = ₅C₅ (0.58)⁵ (0.42)⁵⁻⁵ = 0.066
The most likely result is 3 families.
The probability of at least 3 families is:
0.344 + 0.238 + 0.066 = 0.648

What is rate of interest?The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also earns additional income in terms of the recipient, known as interest, taking into account the time value of money.
Given:
Arianna North borrowed $12,500
She agreed to pay back $13,250 in 270 days.
let x be the interest rate was she paying
x= 13250 - 12500
= 750
So, x= 750/ 12500 (270/ 365)
x% = 750/ 9,246.57
x% = 0.0811
x%= 8.11%
Hence, the exact rate of interest is 8.11%.
