Step-by-step explanation:

The slope of the line is basically the gradient so I used the formula

(y2-y1) / (x2 - x1) which gives (-5-1) / (3-0) = 2

An essential concept in mathematics and can be applied to a variety of fields such as physics, economics, and engineering.

The slope of a line in a Cartesian plane is a numerical representation of its steepness and inclination relative to the x-axis.

The slope of a straight line refers to the rise or fall of the y-coordinate as it moves from left to right along the x-axis.

There are a few different ways to interpret the slope of a line, but generally it can be thought of as the rate at which the dependent variable changes with respect to the independent variable.
When the slope is positive, the line rises from left to right, indicating that the dependent variable is increasing as the independent variable increases.

In other words, there is a direct relationship between the two variables.

Conversely, when the slope is negative, the line falls from left to right, indicating that the dependent variable is decreasing as the independent variable increases.

This means that there is an inverse relationship between the two variables.
The magnitude of the slope can also provide information about the relationship between the variables.

If the slope is close to zero, then the relationship between the two variables is weak or nonexistent.

However, if the slope is large in magnitude (i.e. close to 1 or -1), then there is a strong relationship between the variables.

A slope of zero indicates that there is no change in the dependent variable as the independent variable changes, while a slope of undefined means that the line is vertical and has no slope.

Answer:

6^-2

Step-by-step explanation:

To answer this, you need to know one basic law of indices:

x^-n = 1/x^n

So here 1/36 is the same as 36^-1.

Then we can simply sqr root 36 to give (6^2)^-1.

When two powers are one in and one out of the brackets, they multiply each other. So here it would be 2*-1, which would give -2.

So the answer is 6^-2.

Answer ran 2 3/4 miles in 1/3 of an hour

2 3/4 miles =11/4 miles in 1/3 of hour

11/4 miles divided by 1/3 hr

11/4 ÷ 1/3

11/4 * 3/1 =33/4 =8 1/4 miles in 1 hr

The angle between u and v , after rounding is approximately 121.2 degrees.

To find the angle between two vectors, you can use the dot product formula:
u · v = ||u|| ||v|| cos(theta)
where ||u|| and ||v|| are the magnitudes of the vectors u and v, and theta is the angle between them.
First, we need to calculate the magnitudes of u and v:
||u|| = sqrt((-3)^2 + 4^2) = 5
||v|| = sqrt(7^2 + 5^2) = sqrt(74)
Next, we can calculate the dot product of u and v:
u · v = (-3)(7) + (4)(5) = -1
Now we can use the dot product formula to solve for theta:
-1 = (5)(sqrt(74)) cos(theta)
cos(theta) = -1 / (5 sqrt(74))
theta = acos(-1 / (5 sqrt(74))) ≈ 121.2 degrees

$1 is still with you in your pocket.

From the Question:

cost of Shirt=$97

$49 my mom $49 = $50

Amount borrowed from Mum = $50

Total Amount borrowed from dad and mum:

$50 + $50 =  $100

change in hand:

Total t Amount borrowed from dad and mum - the cost of the Shirt

$100-$97 = $3.

Recall:

I gave $1 to dad and $1 to mom and kept $1 for myself

Money owed  my dad = Amount borrowed from Dad - Amout given to Dad

                                      =$50 -  $1

                                     = $49

Money owed my Mum =Amount borrowed from Mum -Amount given to Mum

                                      =$50 -  $1

                                     = $49

change in hand will be = Amount borrowed from dad and mum - (cost of Shirt +Amout given to Dad +Amount given to Mum)

change in hand will be = $100 -( $97+  $1 +  $1 )

If the credit card did not have a promotional offer, Lori would have had to pay approximately $110.58 more in interest.

a. To determine how long it will take Lori to pay off the balance, we need to calculate the number of months it will take for the total balance to reach zero.

Let's assume it takes n months for Lori to pay off the balance. Each month, Lori pays $75 towards the balance. Since there is no interest during the promotional period, the balance decreases by $75 each month.

The initial balance is $562, so the remaining balance after n months can be represented as:

Remaining balance = Initial balance - (Monthly payment * Number of months)

0 = 562 - (75 * n)

Solving this equation for n:

75n = 562

n = 562 / 75

n ≈ 7.49

Therefore, it will take Lori approximately 7.49 months (or rounded up to 8 months) to pay off the balance.

b. To calculate the total interest paid, we need to subtract the initial balance from the total amount paid over the repayment period. The total amount paid is the monthly payment multiplied by the number of months.

Total interest paid = Total amount paid - Initial balance

Total amount paid = Monthly payment * Number of months

Total interest paid = (Monthly payment * Number of months) - Initial balance

Total interest paid = (75 * 8) - 562

Total interest paid = 600 - 562

Total interest paid = $38

Therefore, Lori will pay a total of $38 in interest.

c. If the credit card did not have a promotional offer, the interest would have been charged at a rate of 19.7% compounded daily after the promotional period.

To calculate the additional interest, we can use the formula for compound interest:

Additional interest = Initial balance * (1 + interest rate)^Number of months - Initial balance

Additional interest = 562 * (1 + 0.197/365)^(30 * 4) - 562

Calculating this value:

Additional interest ≈ $110.58

Therefore, if the credit card did not have a promotional offer, Lori would have had to pay approximately $110.58 more in interest.

P(X ≥ 200) = 1 - P(X < 200) ≈ 1.0. In other words, it is very likely (almost certain) that at least 200 out of 210 college graduates under age 20 are employed.

To find the probability that at least 200 out of 210 college graduates under age 20 are employed, we can use the binomial distribution formula:
P(X ≥ 200) = 1 - P(X < 200)
where X is the number of employed college graduates under age 20 out of a sample of 210.
We know that the unemployment rate for college graduates under the age of 20 is 7%. Therefore, the probability of an individual college graduate being unemployed is 0.07.
To find the probability of X employed college graduates out of 210, we can use the binomial distribution formula:
P(X = k) = (n choose k) * p^k * (1-p)^(n-k)
where n is the sample size (210), k is the number of employed college graduates, and p is the probability of an individual college graduate being employed (1-0.07=0.93).
We want to find P(X < 200), which is the same as finding P(X ≤ 199). We can use the cumulative binomial distribution function on a calculator or software to find this probability:
P(X ≤ 199) = 0.000000000000000000000000000001004 (very small)
Therefore, P(X ≥ 200) = 1 - P(X < 200) ≈ 1.0. In other words, it is very likely (almost certain) that at least 200 out of 210 college graduates under age 20 are employed.

To find the 60th percentile for the given set of data (0, 2, 3, 5, 5, 6, 8, 10, 10, 11, 12, 14, 16), the answer is 8.4.

To determine the 60th percentile, we need to arrange the data in ascending order. The ordered set of data is: 0, 2, 3, 5, 5, 6, 8, 10, 10, 11, 12, 14, 16.

To find the 60th percentile, we need to calculate the position of the value within the data set. Since the percentile represents the percentage of values below a certain point, we can calculate the position using the formula: (p/100) * (n + 1), where p is the percentile and n is the total number of data points.

For the 60th percentile, the calculation would be: (60/100) * (13 + 1) = 7.2. Since the position is not an integer, we can interpolate between the values. The value at the 7th position is 8, and the value at the 8th position is 10. By interpolating, we find that the 60th percentile is 8 + 0.2 * (10 - 8) = 8.4.

Therefore, the 60th percentile for the given set of data is 8.4.

Step-by-step explanation:

To maximize profit, we need to find the critical point(s) of the profit function, P(x, y). Profit is defined as the difference between total revenue and total cost. Thus, the maximum profit is 49 thousand dollars.

The profit function is:
P(x, y) = R(x, y) - C(x, y)
Now substitute the given functions for R(x, y) and C(x, y):
P(x, y) = (7x + 9y) - (2x^2 - 2xy + y^2 - 7x - 9y + 11)
Simplify the profit function:
P(x, y) = -2x^2 + 2xy - y^2 + 14x
Next, find the partial derivatives of the profit function with respect to x and y:
∂P/∂x = -4x + 2y + 14
∂P/∂y = 2x - 2y
To find the critical point(s), set both partial derivatives equal to zero and solve the system of equations:
-4x + 2y + 14 = 0
2x - 2y = 0
Solve for y in the second equation:
y = x
Substitute y = x in the first equation:
-4x + 2x + 14 = 0
-2x + 14 = 0
Solve for x:
x = 7
Now, substitute x back into y = x to find the value of y:
y = 7
So, the number of each type of product that should be manufactured to maximize profit is x = 7 and y = 7, or 7,000 units of product A and 7,000 units of product B.
To find the maximum profit, substitute the values of x and y into the profit function:
P(7, 7) = -2(7^2) + 2(7)(7) - (7^2) + 14(7)
P(7, 7) = -98 + 98 - 49 + 98
