The cost per highlighter is approximately $1.
To find the cost per highlighter, we can use a system of equations. Let's call the cost per highlighter "h" and the cost per pen "p". Then, we can set up two equations based on the information given;
80h + 20p = 120 (day 1)
120h + 40p = 200 (day 2)
We can simplify these equations by dividing both sides by 20;
4h + p = 6 (day 1)
6h + 2p = 10 (day 2)
Now we can use the first equation to solve for p in terms of h;
p = 6 - 4h
Substitute this expression for p into second equation;
6h + 2(6 - 4h) = 10
Simplify and solve for h;
6h + 12 - 8h = 10
-2h = -2
h = 1
Therefore, the cost per highlighter is $1.

a fair die is rolled 100 times.the results are shown below
number:. 1. 2. 3. 4. 5. 6
no of times:. 12. 16. 25. 18. 15. 14
what is the probability of getting
1?
2?
3?
4?
5?
6?
1.) Probability of getting 1: 0.12 or 12%.
2.) Probability of getting 2: 0.16 or 16%.
3.) Probability of getting 3: 0.25 or 25%.
4.) Probability of getting 4: 0.18 or 18%.
5.) Probability of getting 5: 0.15 or 15%.
6.) Probability of getting 6: 0.14 or 14%.
To calculate the probability of getting a specific number on a fair die, we divide the number of times that number appears by the total number of rolls. In this case, the die was rolled 100 times, and the results are given as follows:
Number: 1 2 3 4 5 6
Times: 12 16 25 18 15 14
To find the probability of getting each number, we divide the corresponding number of times by the total number of rolls (100):
Probability of getting 1 = 12 / 100 = 0.12.
Probability of getting 2 = 16 / 100 = 0.16.
Probability of getting 3 = 25 / 100 = 0.25.
Probability of getting 4 = 18 / 100 = 0.18.
Probability of getting 5 = 15 / 100 = 0.15.
Probability of getting 6 = 14 / 100 = 0.14.
Therefore, the probabilities of getting each number on a fair die, based on the given results of 100 rolls, are approximately:
1: 0.12 or 12%,
2: 0.16 or 16%,
3: 0.25 or 25%,
4: 0.18 or 18%,
5: 0.15 or 15%,
6: 0.14 or 14%.

he graph of the function f(x) = (x +2)(x + 6) is shown below. On a coordinate plane, a parabola opens up. It goes through (negative 6, 0), has a vertex at (negative 4, negative 4), and goes through (negative 2, 0). What is true about the domain and range of the function? The domain is all real numbers, and the range is all real numbers greater than or equal to –4. The domain is all real numbers greater than or equal to –4, and the range is all real numbers. The domain is all real numbers such that –6 ≤ x ≤ –2, and the range is all real numbers greater than or equal to –4. The domain is all real numbers greater than or equal to –4, and the range is all real numbers such that –6 ≤ x ≤ –2.
The graph of the function f(x) = (x+2)(x+6) is shown below, with a parabola opening up. It passes through (-6, 0), has a vertex at (-4,-4), and passes through (-2,0). To determine the function's domain and range, you can look at the graph of the function and find out what values of x are allowed and what values of y are possible.
A parabola that opens upwards is defined by a quadratic function whose leading coefficient is positive. The vertex of the parabola is at the minimum point of the function, and the parabola is symmetric about this point. Therefore, if the vertex of a quadratic function is at a point (h,k), then its standard form is:
f(x) = a(x-h)2+k.
In this case, the vertex is at (-4,-4), which means the equation of the parabola is
f(x) = a(x+4)2-4.
We can use the two points (-6,0) and (-2,0) to find the value of a. When x = -6, f(x) = 0, so
we get: 0 = a(-6+4)2-4 0 = 4a-4 a = 1
When x = -2, f(x) = 0, so
we get: 0 = a(-2+4)2-4 0 = 4a-4 a = 1
So, the equation of the parabola is f(x) = (x+4)2-4, and we can see that the graph of the function is symmetric about the vertical line x = -4. Domain and Range of the Function:
The domain of a function is the set of all possible values of the independent variable (x) for which the function is defined. The range of a function is the set of all possible values of the dependent variable (y) that the function can take. Since the equation of the function is
f(x) = (x+4)2-4,
we know that the domain is all real numbers because there are no values of x for which the function is undefined.
The range, on the other hand, is all real numbers greater than or equal to -4. This is because the vertex of the parabola is at (-4,-4), and the function is increasing to the left and right of this point.
Therefore, the minimum value of the function is -4, and it can take on any value greater than or equal to that. Therefore, the correct option is:
The domain is all real numbers, and the range is all real numbers greater than or equal to –4.

On 1 April mazibane has R540, 00 in his credit card account. He buys a lounge suit for R8300, 00 on credit. There is no interest on the debit amount for the first month. Thereafter the interest is 16% per year calculated daily but compounded monthly. On 1 June Mazibane pays R5000 into the account.
How much must Mazibane pay into the account on 30 June to have no debt in the account
According to the information, we can infer that Mazibane must pay R3640 into the account on 30 June to have no debt.
How to calculate the amount Mazubane must pay on 30 June?To calculate the amount Mazibane must pay on 30 June to have no debt in the account, we need to consider the initial debt, the interest, and the previous payment.
Initial Debt:
On 1 April, Mazibane had a credit card debt of R8300.Interest Calculation:
The interest on the debt is 16% per year, calculated daily but compounded monthly. From 1 April to 1 June, a period of two months, there is no interest charged on the debt.Previous Payment:
On 1 June, Mazibane paid R5000 into the account.To determine the remaining debt on 1 June, we subtract the payment from the initial debt:
Remaining debt on 1 June = R8300 - R5000 = R3300.From 1 June to 30 June, a period of one month, interest is charged on the remaining debt.
To calculate the interest for one month, we use the formula:
Interest = Principal x (1 + (rate/100))^(time/12) - Principal,where the principal is the remaining debt, the rate is the monthly interest rate (16%/12), and the time is the number of months (1).
Interest for one month = R3300 x (1 + (16/100)/12)^(1/12) - R3300.To find the total debt on 30 June, we add the remaining debt on 1 June and the interest for one month:
Total debt on 30 June = R3300 + Interest for one month.To have no debt on 30 June, Mazibane must pay the total debt amount:
Mazibane must pay R3300 + Interest for one month on 30 June.Calculating the interest and summing up the values, we find that Mazibane must pay approximately R3640 into the account on 30 June to have no debt.

At 8 AM the temperature was 3 degrees below zero. By 9 AM the temperature had gone up 6 degrees, but by 10 AM it had gone down again 4 degrees, what was the temperature at 10 AM?
Answer:
The temperature at 10 am in the morning was 1 degree below zero.
First, we know at 8 am that the temperature was 3 degrees below zero so that number is -3 and it’s our starting number.
Next, it says an hour later the temperature has gone up 6 degrees so we have -3 + 6 and we get a sum of positive 3.
Finally, at 9 am the temperature dropped again but this time 4 degrees so 3 - 4 = -1
The temperature at 10 am in the morning was 1 degree below zero.
Step-by-step explanation:
Answer:
at 8am it went down -3 below zero
at 9 am it went up +6 degrees
at 10am it went back down -4 degrees
so 6 + (-7) = -1 degrees was the temp at 10 am

which of the classical assumptions would be violated if you decided to add a dummy variable to the equation that was equal to 1 if the ith day was a tuesday, wednesday, thursday, or friday, and equal to 0 otherwise? (hint: the stock market is not open on weekends.)
The classical assumptions would be violated if you decided to add a dummy variable to the equation that was equal to 1 is independence of errors.
In a linear regression equation, the errors are assumed to be independent of each other, meaning that the error for one observation should not be related to the error for any other observation.
However, when you add a dummy variable that indicates whether the day is a weekday or not, you are introducing a systematic pattern into the errors.
Specifically, you are creating a situation where the errors for weekdays will be more similar to each other than to the errors for weekends, because the stock market is closed on weekends.
This violates the assumption of independence of errors, which can lead to biased estimates and unreliable inferences. To address this issue, you could consider including a different dummy variable that indicates whether the day is a weekend or not.
This would help to account for the systematic pattern in the errors and ensure that the classical assumptions are not violated.

He jogging track has a length of 792 yards how long is this in miles
By performing the division, the jogging track is 0.45 miles long.
What is division?Division is a mathematical operation that involves the splitting of a quantity into equal parts or groups.
According to given information:The problem asks us to convert a length of 792 yards to miles. To do this, we need to use a conversion factor to relate yards to miles. We know that there are 1760 yards in a mile, so we can use this relationship to convert the length in yards to miles.
To convert yards to miles, we divide the length in yards by the number of yards in a mile. This is because we want to cancel out the units of yards and be left with the corresponding number of miles.
So, 792 yards / 1760 yards/mile gives us the length of the jogging track in miles. We can simplify this expression by performing the division to get the result of 0.45 miles. Therefore, the jogging track is 0.45 miles long.
