Christian, this is the solution to the problem:
p = 2l + 2w
Solving for l, we have:
2l = p - 2w
Dividng by 2 at both sides:
2l/2 = (p - 2w)/2
l = (p - 2w)/2
The correct answer is D.
When are two events considered to be independent? A. when the occurrence of each event is not affected by the occurrence of the other event B. when the occurrence of the second event affects the occurrence of the first event C. when the occurrence of the first event affects the occurrence of the second event D. when the occurrence of each event affects the occurrence of the other
The two events are considered to be independent when the occurrence of each event is not affected by the occurrence of the other event
The event is defined as the outcome or the set of all the outcomes of the random experiment
Independent event is defined as the occurrence of the one event does not depends on the occurrence of another event
So we can say that, two events are independent events when the occurrence of the one event does not depends on the occurrence of the other event.
Hence, The two events are considered to be independent when the occurrence of each event is not affected by the occurrence of the other event

if the sales tax rate is 6.25% in your city, find the final cost of the item diamond ring : $655.75discount rate: 40%
What is 40% of 655.75??
40% = 40/100 = 0.4
So,
655.75 * 0.4 = $262.30
On top of that, we have to pay a sales tax of 6.25%, which is
6.25% = 6.25/100 = 0.0625
So,
262.30 * 0.0625 = $16.39
We ADD this tax to get final amount:
Amount Paid = 262.30 + 16.39 = $278.69(11^9) over (15^6) to the 4th power
A 11^6 + 4/15^6 +4

Two factory plants are making TV panels. Yesterday, Plant A produced 2000fewer panels than Plant B did. Four percent of the panels from Plant A and 2% of the panels from Plant B were defective. How many panels did Plant B produce, if the two plants together produced 880 defective panels?
Using a series of linear equations, the number of panels generated by Plant B is 16000.
Given,
Plant A produces 2000 fewer panels than Plant B.
Defective percentage of plant A = 4%
Defective percentage of plant B = 2%
To find: Number of useable panels of Plant A and Plant B if 880 are defective.
Let's take, panels produced by Plant B = b
and panels produced by Plant A , a = b - 2000 - - - - (1)
The total number of defective panels :
0.04a + 0.02b = 880 - - - - - (2)
From (1) :
0.04(b - 2000) + 0.02b = 880
0.04b - 80 + 0.02b = 880
0.06b = 880 + 80
0.06b = 960
b = 960 ÷ 0.06
b = 16,000
Therefore, plant B built 16,000 panels.

In a neighborhood donut shop, one type of donut has 560 calories, two types of donuts have 400 calories, five types of donuts have 570 calories, six types of donuts have 450 calories, and seven types of donuts have 550 calories.Find the mean number of calories in these donuts. Round your answer to the nearest whole number, if necessary. caloriesFind the median number of calories in these donuts. calories
ANSWER:
Mean: 512 calories
Median: 550 calories
STEP-BY-STEP EXPLANATION:
The first thing is to determine the data necessary to calculate the mean and median, according to the statement, the data is as follows:
[tex]560,400,400,570,570,570,570,570,450,450,450,450,450,450,550,550,550,550,550,550,550[/tex]The mean is the average value of a set of numeric data, calculated as the sum of the set of values divided by the total number of values:
[tex]\begin{gathered} m=\frac{560+400+400+570+570+570+570+570+450+450+450+450+450+450+550+550+550+550+550+550+550}{21} \\ m=\frac{10760}{21}=512.38\cong512 \end{gathered}[/tex]The median is a central position statistic that splits the distribution in two, that is, it leaves the same number of values on one side as on the other. To calculate the median it is important that the data are ordered from highest to lowest, or conversely from lowest to highest, therefore, we organize:
[tex]400,400,450,450,450,450,450,450,550,550,550,550,550,550,550,560,570,570,570,570,570[/tex]The value in the middle after arranging is 550, therefore the median is 550 calories.

What is the H.c.f of 16 and 30
The HCF of 16 and 30 is 2.
What is HCF?The greatest number that totally divides two numbers is known as the Highest Common Factor (HCF). The Greatest Common Divisor (GCD) is another name for the Highest Common Factor (HCF) (GCD).The HCF of two numbers can be determined in a variety of methods. Using the prime factorization technique is one of the easiest techniques to determine the HCF of two or more numbers.SO, the given numbers are 16 and 30
The prime factorization of 16 and 30 are as follows:
16 = 2 × 2 × 2 × 230 = 2 × 3 × 5Multiply all the prime factors that both numbers share in order to determine the HCF:Thus, HCF is = 2.

Find the area of the rectangle that has a perimeter of 8x − 14 units and a length of x − 5 units.
Answer: Area = 4 square units
Perimeter of the rectangle = 8x - 14 units
Length of the rectangle = x - 5 units
Let the width of the rectangle = x units
Perimeter = 2( length + width)
8x - 14 = 2(x - 5 + x)
Solve the parenthesis for once
8x - 14 = 2(x + x - 5)
8x - 14 = 2(2x - 5)
8x - 14 = 4x - 10
Collect the like terms
8x - 4x = -10 + 14
4x = 4
Divide both sides by 4
4x/4 = 4/4
x = 1
Since, the length is x - 5 units
Length = 1 - 5
Length = - 4units
Length = 4 units
Width = 1 unit
Area = length x width
Area = 4 x 1
Area = 4 square units

1) Let's rewrite that radical, in a way that we can eliminate the fourth root:
[tex]18\sqrt[4]{5}\Rightarrow(18\sqrt[4]{5})^8=18^8\cdot(\sqrt[4]{5})^8=18^8\text{ }\sqrt[]{25}[/tex]2) This way we can get rid of the fourth root by raising to the power (in this case 8) as the index of the root (4).
