Graph the line y=kx+1 if it is known that the point M belongs to it: M(1, 3)
Answer:
Ok, we have the line:
y = k*x + 1
And we know that the point (1, 3) belongs to this line.
This means that when x is equal to 1, y must be equal to 3.
Then:
3 = k*1 + 1
3 - 1 = k
2 = k
Now we know that our line is:
y = 2*x + 1.
And we can graph it, as shown below.

Denis is currently unemployed and wants to
become the manager of Roberto's
Restaurant. To become a manager in
Roberto's Restaurant, Denis first has to serve
as a cook there. To become a cook in
Roberto's Restaurant, he first has to serve as
a waiter there.
Denis has a 60% chance of being hired as a
waiter. If he becomes a waiter, he has a 50%
chance of being promoted to cook. If he
becomes a cook, he has a 40% chance of
being promoted to manager.
At Roberto's Restaurant, managers get paid
$25 per hour, cooks get paid $15 per hour,
and waiters get paid $10 per hour. If Denis
stays unemployed, he will make $0 per hour.
What is the expected hourly payoff of
Denis's plan to seek employment at
Roberto's Restaurant?
Round your answer to the nearest cent.
The expected hourly payoff of Denis's plan to seek employment at Roberto's Restaurant is $16.50.
To calculate the expected hourly payoff of Denis's plan, we need to consider the probabilities of each step and the respective pay rates.
1. Probability of becoming a waiter: 60% (0.60)
Pay rate as a waiter: $10 per hour
2. Probability of being promoted to cook given he becomes a waiter: 50% (0.50)
Pay rate as a cook: $15 per hour
3. Probability of being promoted to manager given he becomes a cook: 40% (0.40)
Pay rate as a manager: $25 per hour
Now, let's calculate the expected hourly payoff:
Expected hourly payoff = (Probability of each step) * (Pay rate at each step)
Expected hourly payoff = (0.60 * $10) + (0.60 * 0.50 * $15) + (0.60 * 0.50 * 0.40 * $25)
Expected hourly payoff = $6 + $4.50 + $6
Expected hourly payoff = $16.50
Therefore, the expected hourly payoff of Denis's plan to seek employment at Roberto's Restaurant is $16.50.

Nancy is curious if the consumption of sweets, mainly donuts, increases as people get older. Nancy asked 200 customers at a local Krispy Kreme how many donuts they eat in a month, y, and recorded their age, x. She obtained the following regression line y=47-1.36x. What is the meaning of the slope of this regression line
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Number of donuts consumed in a month = y
Age = x
Regression equation obtained :
y=47-1.36x
Meaning of slope of the regression line ;
Comparing the regression equation obtained with the general equation of a linear regression line ;
y = mx + c; where m = slope of the regression line
Hence, the value of slope in the equation is = - 1.36
Thus, the slope can be interpreted as ; The number of donuts consumed in a month is expected to decrease by 1.36 for per(1) increase in age x of consumer.
The slope means that the number of donuts reduces by 1.36 as people get older.
A linear equation is in the form:
y = mx + b;
where y, x are variable, m is the slope of the line and b is the y intercept.
Let y represent the number of donut ate by the customers in a month and x represent their age
Given the regression line:
y = 47 - 1.36x
The slope means that the number of donuts reduces by 1.36 as people get older.

b. Use the Empirical Rule to determine the percentage of M&Ms with weights between 0.803 and 0.947 gram. Hint: = 0.875.
c. Determine the actual percentage of M&Ms that weigh between 0.803 and 0.947 gram, inclusive.
d. Use the Empirical Rule to determine the percentage of M&Ms with weights more than 0.911 gram.
e. Determine the actual percentage of M&Ms that weigh more than 0.911 gram.
Answer:
a)0.03558
b) 95%
c) 95.6985%
d) 16%
e)15.58%
Step-by-step explanation:
a) Determine the sample standard deviation weight.
Step 1
We find the Mean
Sum of terms/ Number of terms
Number of terms = 50
= 43.73/50
= 0.8746 grams
≈ 0.875 grams
Formula for sample standard deviation = √(x - Mean)²/n - 1
= √0.062042/50 - 1
= √0.001266163265
= 0.03558318796 grams
The empirical rule formula:
1) 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .
2) 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
3)99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ
b. Use the Empirical Rule to determine the percentage of M&Ms with weights between 0.803 and 0.947 gram. Hint: = 0.875.
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
μ – 2σ
0.875 - 0.03558 × 2
= 0.80384
μ + 2σ
= 0.875 + 0.03558 × 2
= 0.94616
Hence, 95% of M&Ms with weights between 0.803 and 0.947 gram.
c. Determine the actual percentage of M&Ms that weigh between 0.803 and 0.947 gram, inclusive.
The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
For x = 0.803
= 0.803 - 0.875/0.03558
= -2.02361
Probability value from Z-Table:
P(x = 0.803) = 0.021505
For x = 0.947
= 0.947 - 0.875/0.03558
= = 2.02361
Probability value from Z-Table:
P(x = 0.947) = 0.97849
Hence,
P(x = 0.947 ) - P(x = 0.803)
= 0.97849 -0.021505
= 0.956985
Converting to percentage
= 0.956985 × 100
= 95.6985%
d. Use the Empirical Rule to determine the percentage of M&Ms with weights more than 0.911 gram.
68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .
=Mean = 0.875
Standard deviation = 0.03558
μ + σ
0.875 + 0.03558
= 0.91058
≈ 0.911
Hence, 68% of M&Ms with weights more than 0.911 gram.
Therefore, percentage of M&Ms with weights more than 0.911 gram, is on the right hand side(one side of the distribution)
=( 100 - 68)%/2
= 32%/2
= 16%
e. Determine the actual percentage of M&Ms that weigh more than 0.911 gram
The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
Mean = 0.875
Standard deviation = 0.03558
x = 0.911
= 0.911 - 0.875/0.03558
= = 1.0118
Probability value from Z-Table:
P(x<0.911) = 0.84418
P(x>0.911) = 1 - P(x<0.911) = 0.15582
Converting to percentage =
0.15582 × 100
= 15.58%

The marked price of an article is Rs. 2200, After allowing a certain percent of disc amount from the with 13% Value Added Tax (VAT) levied, the article is sold at Rs. 2063.38. Find discount percent
To sell the article at a price of Rs. 2063.38 after applying 13% VAT, a discount of approximately 6.21% is given on the marked price of Rs. 2200.
Let's break down the given information to solve for the discount percent:
1. The marked price of the article is Rs. 2200.
2. After allowing a certain percent of discount, the article is sold at Rs. 2063.38, including 13% VAT.
Let's assume the discount percent as 'x'. We can calculate the discounted price using the formula:
Discounted Price = Marked Price - (Discount Percent/100) * Marked Price
Substituting the given values, we have:
2063.38 = 2200 - (x/100) * 2200
Now, let's solve the equation to find the value of 'x':
2063.38 = 2200 - 22x
Rearranging the equation, we have:
22x = 2200 - 2063.38
22x = 136.62
x = 136.62 / 22
x ≈ 6.21
Therefore, the discount percent is approximately 6.21%.

Antonio is at the grocery store. His favorite mac and cheese costs $1.60 per box. There is a sale: Buy 4 boxes, save $1. How much will the mac and cheese cost if he buys 4 boxes?
Answer:
$5.40
Step-by-step explanation:
1.60 times 4 equals $6.40 and subtract the dollar off
The cost for the mac and cheese for Antonio is $5.40.
What is Multiplication?Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Cost of one box of mac and cheese = $1.60
The sale is that if someone buy 4 boxes. there is a discount of 1 dollar.
If Antonio buys 4 boxes,
Cost of 4 boxes of mac and cheese = 4 × $1.60
= $6.4
Total cost of 4 boxes = $6.40
But there is a save of $1.
Cost of 4 boxes after saving $1 = $6.40 - $1.00 = $5.40
Hence mac and cheese costs $5.40 for him.

Julie and Eric row their boat (at a constant speed) 55 miles downstream for 5 hours, helped by the
current. Rowing at the same rate, the trip back against the current takes 11 hours. Find the rate of
the current
Answer: C = 3 mph is the rate of the current.
Step-by-step explanation:
Hey there!
You can use the distance formula (d = rt) to solve this problem.
Downstream trip: d = 55 miles, t = 5 hours, and r = R + C
R + C is their rowing speed (R) plus the rate of the current (C).
Upstream trip: d = 55 miles, t = 11 hours, and r = R - C
R - C is their rowing speed (R) minus the rate of the current (C).
Downstream: 55 mi. = (R + C)5 hrs. Divide both sides by 5: R + C = 11
Upstream: 55 mi. = (R - C)11 hrs. Divide both sides by 11: R - C = 5
Calculations
R + C = 11 Subtract C from both sides.
R = 11 - C Substitute this into: R - C = 5
(11 - C) - C = 5 Simplify and solve for C
11 - 2C = 5 Add 2C to both sides.
11 = 2C + 5 Subtract 5 from both sides.
6 = 2C Divide both sides by 2
C = 3 mph is the rate of the current.
