a. The equation of the trend line is c=5x+100.
b. The equation of the trend line is c=-5x+100.
c. As the hours of training increase by 5, the greeting cards made increases by 25.
d. As the hours of training increase by 5, the greeting cards made decreases by 25.
Answer:
The slope of the line of best fit is 5.
Without any training, an employee is expected to make 100 greeting cards.
If an employee has 70 hours of training, the employee is expected to make 450 greeting cards per month.
Step-by-step explanation:
First, find the slope of the line of best fit by substituting any two points on the line into the slope formula. The following calculation uses (10,150) and (20,200).
So, the slope of the line of best fit is 5.
The y-intercept is the point at which the line crosses the y-axis or when x = 0. So, the y-intercept of the line of best fit is 100.
The equation of the line of best fit can be represented in slope-intercept form, where the slope, m, is 5 and the y-intercept, b, is 100.
A slope of 5 in this situation means that for every additional hour of training, 5 more greeting cards are expected to be made per month. The y-intercept is 100 when the number of hours of training is 0. So, without any training, an employee is expected to make 100 greeting cards.
To find the number of greeting cards an employee would produce after receiving 70 hours of training, substitute x = 70 into the equation for the line of best fit and solve for y.
So, if an employee has 70 hours of training, the employee is expected to make 450 greeting cards per month.

Answer:
6x^3-12x^2+3x-3
Step-by-step explanation:
Answer:
6x³ - 12x² + 3x - 3
Step-by-step explanation:
f(x) - g(x)
= (6x³ - 3x² + 4x - 4) - (9x² + x - 1)
= 6x³ - 3x² + 4x - 4 - 9x² - x + 1
= 6x³ - 3x² - 9x² + 4x - x - 4 + 1
= 6x³ - 12x² + 3x - 3
Evaluate.0.2 power of 4 =
Answer:
0.0016
Step-by-step explanation:
The expression 0.2 by the power of 4 when evaluated has a value of 0.0016
How to evaluate the expressionFrom the question, we have the following parameters that can be used in our computation:
0.2 by the power of 4
Express as an equation
So, we have
0.2 by the power of 4 = 0.2⁴
When expanded, we have
0.2 by the power of 4 = 0.2 * 0.2 * 0.2 * 0.2
Evaluate the products
This gives
0.2 by the power of 4 = 0.0016
Hence, the solution is 0.0016

Please, if anyone knows help me, I need a lot of help in this activity.
Answer:
Step-by-step explanation:
Perimeter of the given polygon = n + 2 + 3 + 4 + n + 2 + 3 + 4
= 2(n + 2 + 3 + 4)
= 2(n + 9) units
Area of the composite figure = Area of rectangle A + Area of rectangle B + Area of rectangle C
= (3 × 4) + (n ×2) + (2 × 3)
= 12 + 2n + 6
= 2n + 18
= 2(n + 9) units²
Therefore, perimeter of the given figure = Area of the figure

Factor completely: 2x^3-12x^2+18x
Answer:
2x(x - 3)²
Step-by-step explanation:
We can simplify this a lot by first factoring 2x out of each term:
2x³ - 12x² + 18x
= 2x(x² - 6 + 9)
We can then factor the trinomial fairly easily, as it's a perfect square:
= 2x(x - 3)²

You are organizing a school banquet. You spend $82 on decorations. Dinner will cost $13 for each person that attends. In the equation y=13x+82, y is the total cost of the banquet for x people. Complete the solution (69,?) to find the cost for 69 people.
Answer:
(69,979)
Step-by-step explanation:
In the coordinates, x is represented as 69. We can now insert this into the equation.
y = 13x + 82
Now to insert x.
y = 13(69) + 82
Now we can multiply 13 by 69.
13*69 = 897
Now fix the equation.
y = 897 + 82
Now add to get our y.
897 + 82 = 979
Substitute into the equation.
y = 979
And there is our answer. We now need to put this into the coordinates.
And we get our final answer of (69,979).
Hope this helps. Have a nice day.
A store purchased a plasma screen TV for $770 and marked it up 150%. During a sale, the store marked it down 20%. What was the discount price on the plasma screen TV?
Answer:
1540
Step-by-step explanation:
First find the new price after the markup
The markup is
770 * 150%
770 * 1.5
1155
Add this to the original price
770 + 1155
1925
Now find the discount
1925*20%
1925*.20
385
Subtract this amount from the 1925
1925-385
1540
The final price is 1540
Answer:
Solution given:
cost price [c.p] of TV =$770
MP=c.p+ 150% of c.p=$770+150/100×770=$1925
discount [D]=20%
now
discount amount=D% of MP=20/100×1925=$385 is your answer.
$385 was the discount price on the plasma screen TV.

Apple juice and cranberry juice have been mixed in the ratio of 4:5. If the price of apple juice is 45 cents per pint and the price of cranberry juice is $0.8 per pint, what should the price of one pint of the mixture be?
Answer:
$0.24
Step-by-step explanation:
The computation of the price of the one pint of the mixture is shown below:
Since the ratio of apple juice and cranberry juice is 4:5
And, the price of apple juice is 45 cents i.e. = 0.45 × 4 ÷ 9 = 0.2
Also the price of cranberry juice is $0.8 = $0.08 × 5 ÷ 9 = 0.04
SO, the price of one pint of the mixture is
= 0.2 + 0.04
= $0.24

$0.24444
