lynn got the better deal than Roger.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
lynn bought a new crash cymbal for her drum set. it costs 120$ but she received a 15% student discount.
Convert 15% to decimal form
15%=15/100=0.15
0.15×120=18
So 15% of 120 is 18.
Iynn bought crash cymbal for her drum set is 120-18=102
Roger bought the same crash cymbal from another store for$130
Roger applied coupon of $25.
So 130-25=$105
When we compare both Iynn and Roger, Iynn got the crash cymbal for a better deal.
Hence lynn got the better deal than Roger.

If P= (2, 7) and Q= (2, -3), which could be the coordinates of R if triangle PQR is isosceles?
If P= (2, 7) and Q= (2, -3), then for triangle to be isosceles coordinate of R must be 2
Let coordinates

A = $160B = $165C = $340D = 252.2. The Cost of Ending Inventory and the Cost of Goods Sold under LIFO, FIFO, and Weighted-Average, are as follows:
LIFO FIFO Weighted-Average
Ending inventory $425 $691 $573
Cost of goods sold $492 $226 $344
How do the inventory methods differ?FIFO (First-in, First-out) lies on the assumption that the physical flow of goods sold depends on the chronological order of acquisition.
LIFO (Last-in, First-out) assumes that the cost of goods sold should be based on the latest inventory purchases.
The weighted-average method uses the average cost of goods to determine both the ending inventory and the cost of goods sold.
LIFO:
Ending inventory = $425 ($917 - $492)
Cost of goods sold = $492 (12 x $20 + 12 x $21)
FIFO:
Ending inventory = $691 (9 x $11 + 17 x $20 + 12 x $21)
Cost of goods sold = $226 ($917 - $691)
Weighted Average:
Ending inventory = $573 (40 x $14.33)
Cost of goods sold = $344 (24 x $14.33)

a vegetable seller purchased 1 quintal of potatoes at rs 35 per kg and sold at a loss of rs 350. find his rate of selling price and loss percent
Answer:
Selling price = RS 3150
Loss percent = 10%
Step-by-step explanation:
1 quintal = 100kg
Cost price = 35*100
= RS 3500
Loss = RS 350
Selling price = RS 3500-350
Selling price = RS 3500-350 =RS 3150
Loss percent = Loss *100%
Cost Price

By the end of the year, 18 cans were sold. Calculate (A) the number of cans of soup ending inventory and (B) the cost of ending inventory under LIFO, FIFO, and weighted average. (Round your final answers to the nearest cent.)
A) The number of cans of soup in ending inventory is 19.
B) The cost of the ending inventory under LIFO, FIFO, and the weighted average is as follows:
LIFO $17.15
FIFO $25.65
Weighted average $21.47
What are the inventory methods?The inventory methods include First-in, First-out (FIFO), Last-in, First-out (LIFO), Weighted Average, and Specific Identification.
FIFO assumes that the physical flow of goods during sales follows the chronological sequence of their acquisition.
LIFO assumes that the first goods acquired are the last to be sold.
The Weighted Average uses an average to determine the costs allocated to ending inventory and the cost of goods sold.
Specific Identification identifies the specific goods sold with their costs.
Description Units Unit Cost Total
Beginning inventory 12 $0.85 $10.20
Purchases 4 $0.95 $3.80

Sales 18
Ending inventory 19 (37 - 18)
Average cost = $1.13 ($41.75/37)
LIFO:
Ending inventory = $17.15 ($10.20 + $3.80 + 3 x $1.05)

A company that most adults would erase all of their personal data online if they could. In order to test this claim, a GFI Software Survey of 565 randomly selected adults showed that 59% of them would erase all of their personal information online if they could.
A. State the null and alternative hypotheses (in symbols).
B. Explain what a Type 1 and a Type 2 error would be in this case.
C. State the conclusion if the null hypothesis is rejected.
D. State the conclusion if the null hypothesis is not rejected.
a) The null and alternative hypothesis are given as follows:
Null: [tex]H_0: p \leq 0.5[/tex]Alternative: [tex]H_1: p > 0.5[/tex]b) The errors are given as follows:
Type I: A sample which gives enough evidence that most people would erase the data, if in reality they wouldn't.Type II: A sample in which the proportion of people that would erase their data isn't significantly above 50%, when in fact it is.c) The conclusion of a rejected null hypothesis is: There is enough evidence that most adults would erase their data if they could.
d) The conclusion of a not rejected null hypothesis is: There is not enough evidence that most adults would erase their data if they could.
What are the hypothesis tested?At the null hypothesis, it is tested if there is not enough evidence that most adults would erase all of their personal data online if they could, that is, if the proportion is not greater than 50%, hence:
[tex]H_0: p \leq 0.5[/tex]
At the alternative hypothesis, it is tested if there is enough evidence that they would erase the information, that is, if the proportion is greater than 50%, hence:
[tex]H_1: p > 0.5[/tex]
A rejected null hypothesis means that the alternative hypothesis is accepted, that is, there is enough evidence that most adults would erase their data if they could.
A not rejected null hypothesis, conversely, means that there is not enough evidence that most adults would erase their data if they could.
What are type I and type II errors?Type I errors are when a true null hypothesis is rejected. Hence, the context of this problem, it would mean a sample which gives enough evidence that most people would erase the data, if in reality they wouldn't.
Type II errors are when a false null hypothesis is not rejected. Hence, the context of this problem, it would mean a sample in which the proportion of people that would erase their data isn't significantly above 50%, when in fact it is.

O It takes less time to fall because it has the most surface area.
O It takes the same amount of time to fall because the effect of gravity is the same.
O It takes less time to fall because it has the least mass
O It takes longer to fall because it experiences greater air resistance.
Answer:
the last one= It takes longer to fall because it experiences greater air resistance.

What is surface area of a cylinder?A cylinder is a three-dimensional solid that contains two parallel bases connected by a curved surface. The bases are usually circular in shape. The perpendicular distance between the bases is denoted as the height “h” of the cylinder and “r” is the radius of the cylinder.
The total surface area of a cylinder is 2πr(r+h)

an expression for the number of bottles they
collected altogether.
The required expression is Total = 152+x .
What is expression ?
Mathematical statements called expressions must contain a minimum of two terms with either numbers, variables, or both, joined by an operator. The four different types of mathematical operators are addition, subtraction, multiplication, and division. For instance, the expression x + y is an expression where x and y are terms with an addition operator between them. Mathematical expressions can be divided into two categories: algebraic expressions, which include both numbers and variables, and numerical expressions, which solely contain numbers.
Here,
The number of bottles Enrique collected = 152
Let us take number of bottles collected by Latasha as x. Then,
Total number of bottles collected by the is ,
=> Total = Number of bottles collected + Number of bottle collected
by Enrique By Latasha.

What is a mean value theorem?The mean value theorem in mathematics says that for any given planar arc between two endpoints, there exists at least one point where the tangent to the arc is parallel to the secant between its endpoints. It is one of the most significant findings in the real-world analysis.
Given that the function is f(x) = 5√x and the interval is (4,9).
Calculate the value of 'c' as below,
f(x) = 5√x
f(4) = 5√4 = 10
f(9) = 5√9 = 15
Calculate the value of f'(c) as below,
f'(c) = ( f(b) - f(a) ) / (b - a)
f'(c) = f(9) - f(4) / ( 9 - 4 )
f'(c) = (15 - 10 ) / ( 9 - 4)
f'(c) = 1
Again the value of f'(x) is,
f'(x) = 5/2/√x
f'(c) = 5 / 2 / (√c)
5 / 2 / (√c) = 1
√c = 5 / 2
c = 25 / 4
c = 6.25

Determine which integer will make the inequality 12 > 2x + 4 true.
Answer: Integers less than 4 will make the inequality true.
Step-by-step explanation:
1) subtract both sides by 4 to isolate 2x so we are now left with 8 > 2x.
2) divide both sides by 2 so we are left with just x, leaving us now with 4 > x.
Integers must be less than 4 because if you substitute x as 4, we have 12 > 12, which is not true. But, if we substitute x as 3, we are left with 12 > 10, which makes the inequality true.
