Perla buys the star necklace that is originally $49.95 but is currently on sale for 62% off. If she gets an additional 20% off, what is the final price of the necklace?
Answer:
Step-by-step explanation:
Remark
It's not 82.
You have to take the 62% off and then follow it with 20% from the new price.
Solution
62%
If you get a reduction of 62%, it means that you pay 100% - 62% = 38% of the marked price of $49.95.
38% price =49.95 * 62/100
38% price = 3096.9 / 100
38% price = $30.97
20% Reduction
20% more means that you pay 100% - 20% = 80%
20% more reduction = 30.97 * 80/100
20% more reduction = 2478/100
20% more reduction = 24.78
Conclusion.
Your final price before taxes is $24.78

Step-by-step explanation:
The table shows the types of movies and the number of DVDs reented by customers at a Red Box in one
Based on the data in the table, what is the probability that a random customer will not rent a drama?
Answer:
A
Step-by-step explanation:
The probability that a random customer will not rent a drama is 4/5. Option B is correct.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
here,
Total number of rented DVDs = 25 + 36 + 52 + 12 = 125
Number of Drama movies = 25
The probability that a random customer will rent a drama.
P(D) = 25 / 125 = 1/5
Now,
The probability that a random customer will not rent a drama,
P(D)' = 1 - P(D)
= 1 - 1/5 = 4/5
Thus, the probability that a random customer will not rent a drama is 4/5. Option B is correct.

Karen recorded the numbers of people getting off her tram. The mean number for 10 stops is 6.3. After the tram stops at the 11th stop, the mean is 8. How many people got off the tram at the 11th stop?
Answer:
32 people got off
Step-by-step explanation:For the 10th stop, we can get the total number of people that have gotten off
Mathematically, this is the product of the mean and the number of stops
= 10 * 6.3 = 63 people
Now, for the 11th stop, the total becomes
11 * 8.6 = 94.6

Answer:
There are three possible outcomes for a system of linear equations: one unique solution, infinitely many solutions, and no solution.
Step-by-step explanation:
9514 1404 393
Answer:
no solutionsa finite non-zero number of solutionsinfinite solutionsStep-by-step explanation:
1. No Solutions
This case arises when the equations are inconsistent. No values of the variables can satisfy all of the equations. An example is ...
y = xy = x+1__
2. Finite Number of Solutions
The number of distinct solutions depends on the degree of the system and the domain being considered. For example, an n-th degree polynomial equation in one variable will always have n solutions in the domain of complex numbers. However, it may or may not have any real-number solutions. (The question here has no context, so we have to assume it is about any system of equations of any degree or nature (rational, polynomial, exponential, mixed, or other.))
__
3. Infinite solutions
An under-specified system, such as a system of 3 equations in 4 variables, may have an infinite number of solutions. In such a system, one or more of the variables may be allowed to assume any value. Systems that have dependent equations will fall into this category.

A rectangular dog pen has an area of 64xy square units. The width is 4y. Write an expression for the length.
Answer:
An expression for the length is:
[tex]l=16x[/tex]Step-by-step explanation:
Given
Area of a rectangular dog pen = A = 64xy square units
Width = w = 4y
To determine
The length = l = ?
We know that the area of a rectangular object is
A = l × w
where w is the width and l is the length of the rectangle.
substituting w = 4y and A = 64xy in the equation
[tex]A=l\times w[/tex]
[tex]64xy\:=l\times 4y\:[/tex]
[tex]\:\:l=\frac{64xy\:}{4y\:\:}[/tex]
Divide the numbers: 64/4 = 16
[tex]l=\frac{16xy}{y}[/tex]
Cancel the common factor: y
[tex]l=16x[/tex]
Therefore, an expression for the length is:
[tex]l=16x[/tex]help me plz and thx :)

I am sure it is false. becuase a dependent variable is something you measure and you have to count the eggs.

Find the length of the missing side. Simplify all radicals. please show explanation!
Answer:
b = 12
Step-by-step explanation:
Using the Pythagorean Theorem:
a² + b² = c²
You can identify that 12√12 is the hypotenuse, as it is opposite to the right angle.
So:
12² + b² = (12√2)²
144 + b² = [(12√2) (12√2)]
144 + b² = (12 × √2 × 12 × √2)
144 + b² = (144 × 2)
144 + b² = 288
b² = 144
√b² = √144
b = 12

How would you solve this?
Answer:
Step-by-step explanation:
Find the slope = -2/1
Find the y-intercept = 5
Go to graph
put a dot at (0,5)
since it's a negative slope you will go up 2 and left 1
draw your line
_________________________________________________
Find the slope = 3/1
Find the y-intercept = 0
go to graph
Put a dot at (0,0)
Since it is a positive slope you will go down 3 and left 1.
To find the slope and y-intercept use this formula=
y=mx+b
m=slope
b=y-intercept

Mario made 2 goals for every 5 shots on goal. What is the probability that Mario would make 2 goals on two shots?
Answer:
16%
Step-by-step explanation:
To calculate this we first need to calculate the probability of Mario scoring for every individual shot that he takes. Since he makes 2 goals for every 5 shots on average, we simply divide these numbers to get the probability of a goal per shot.
2 / 5 = 0.4 ...multiply by 100 to get percentage value
0.40 * 100 = 40%
We see that the probability of scoring a goal per shot is 40%. Now we need to multiply this probability twice to get the probability of scoring 2 consecutive goals in two shots.
0.40 * 0.40 = 0.16 ... multiply by 100 to get percentage value
0.16 * 100 = 16%
Answer:
16%
Step-by-step explanation:
I know that 2/5 = 0.4 or 40%
and 0.4 x 0.4 = 0.16
or 16%
