There are x melons and y oranges. The product of integers x and y is
539. The number of melons is 11 times of that of oranges, How many
melon(s) is / are there?
Answers
Answer:
77 melons
Step-by-step explanation:
[tex]11x \times x = 539 \\ 11 {x}^{2} = 539 \\ \frac{11x}{11} = \frac{539}{49} \\ {x}^{2} = 49 \\ \sqrt{ {x}^{2} } = \sqrt{49} \\ x = 7[/tex]
The oranges are 7
And the melons are 11 times the number of the oranges hence
11 x 7= 77

The heights of the starting 5 players (not including the libero) on a volleyball team like karasuno high school are 60 inches, 67 inches, 64 inches, and 65 inches. If the balance point of the players is 65, what is the height of the 5th player?.
Answers
The height of the 5th player would be 69 inches
To find the Height, first, we have to calculate the mean value.
No. of players=5
The height of 4 players is 60 inches, 67 inches, and 64 inches, 65 inches.
Mean =Sum of observations/No of observations
Mean of the 5th players=65
To find, Height of 5th player
As we know,
Assuming the height of the 5th player is x
Mean =Sum of observations/No of observations
65=(60+67+64+65+x)/5
65*5=60+67+64+65+x
325=256+x
x=69
Thus, the height of the 5th player is 69 inches.

three less than twice an integer is greater than 1
Answers
2x - 3 > 1
x represents an integer and 3 is less than twice an integer which is 2x. So it's 2x - 3.
2x - 3 is greater than 1.
So therefore, the answer is 2x - 3 > 1
Answer:
2x-3>1
Step-by-step explanation:
lets say x is the interger
so twice an interger would be 2*x or 2x
and three less than that would be 2x-3
and 2x-3 is greater than one

(a) how many 4-permutations are there of a set of six objects? (b) how many 2-permutations are there of a set of nine objects?
Answers
There will be a total of 720 4- permutations of a set of six objects. And there will be a total of 72 2- permutations of a set of nine objects.
The calculation for 4-permutations of a set containing six objects
P(6,4)! = 6! / (6-4)1
P(6,4)! = 6×5×4×3x2
P(6,4)! = 720
Therefore, there will be a total of 720 permutations.
The calculation for 2- permutation of a set containing 9 objects
P(9,2)! = (9,7)! = (9-2) = 9! / 7!
P(9,2)! = 9×8x7! / 7!
P(9,2)! = 72
Therefore, there will be a total of 72 permutations.

The size of the standard version is 2.8 megabytes (MB). The size of the high-quality version is 4.3 MB. Yesterday, the high-quality version was downloaded four times as often as the standard version. The total size downloaded for the two versions was 4600 MB. How many downloads of the standard version were there?
Answers
Answer:
The number of downloads of the standard version is 230.
Step-by-step explanation:
Let x be the number of downloads of the standard version.
The number of downloads of the high-quality version is 4x.
The total size downloaded for the standard version is 2.8x MB.
The total size downloaded for the high-quality version is 4.3(4x) = 17.2x MB.
The total size downloaded for both versions is 2.8x + 17.2x = 4600 MB.
Combining like terms, we have 20x = 4600 MB.
Dividing both sides by 20, we have x = 230 downloads of the standard version

julian's transcript shows a grade point average of 3.00, with a standard deviation of 0.25. what fraction of his total credits were certain to have a grade point average between 2.00 and 4.0?
Answers
At least 75% of his total credits were certain to have a grade point average between 2.00 and 4.0.
By looking at the standard deviation of 0.25, we can calculate the range of the grade point averages which are within two standard deviations away from the mean. In this case, the mean is 3.00, so two standard deviations away would be 2.00 (3.00 - 0.25 x 2) and 4.00 (3.00 + 0.25 x 2). Since the grade point averages within this range are certain to have a grade point average between 2.00 and 4.0, at least 75% of the total credits are certain to have a grade point average between these two numbers.
Lower limit (2 standard deviations away from the mean):
3.00 - (0.25 x 2) = 2.00
Upper limit (2 standard deviations away from the mean):
3.00 + (0.25 x 2) = 4.00
Therefore, at least 75% of the total credits have a grade point average between 2.00 and 4.00.

The sum of 3 consecutive even numbers is 54 what’s the largest number
Answers
The largest number is 20 .
What is largest ?
There is a big number—a googolplex—that exists. It consists of 1 and 10100 zeros (googol). A googolduplex, which is an even larger number, is also present. It is 1 and over a googol zeros after that.
Let 'n' be any number, odd or even.
2n will always be even number. This is because, 2n has 2 as common factor. So, 2n is always even.
Eg: 2= 2×1, n=1 ; 4=2×2, n=2 etc
Numbers are even, consecutive.
Consecutive even numbers are 2n-2, 2n, 2n+2,
Eg : For consecutive even numbers, put n=2
2n-2=4-2=2
2n=4
2n+2 =4+2=6,
we get 2,4,6 which are consecutive even nos.
So, numbers are 2n-2, 2n and 2n+2
Their sum= 2n+2+2n+2n-2=6n
Sum=54
6n=54
n=54/6=9
So, n=9
Consecutive numbers are
2n-2= (2×9)-2=16
2n=2×9=18
2n+2=18+2=20.
So, numbers are 16, 18, 20. Their sum is 54.

Answers
As per the impact of reducing the tolerable rate of deviation from 7% to 5% on the sample size is 93.
The term deviation is defined as a measure that is used to find the difference between the observed value and the expected value of a variable.
Here we have given that the audit team is planning to examine a sample of control policies and procedures. assume that, based on the intended degree of reliance on internal control, the audit team wishes to control the risk of overreliance to 5%.
And we need to find sample size.
While we looking into the given question, we know that the tolerable rate of deviation from 7% to 5% on the sample size.
Let us consider that 100 be the sample size, then the reduction in 7% to 5%, tell that there is an 2% decrement in the sample size.
Therefore, it can be calculated as,
=> 100 x 2/100
=> 2
Here we already know that the risk of overreliance to 5%.

The city planner wants to put recycling bins at the circumcenter of the park. What are the coordinates of the recycling bins?.

The coordinates of the recycle bin will be = ( -1, 2.5 )
According to the information given in the question,
The coordinates of the vertices of the park are,
( 1, 1 ), ( 1, 4 ), and ( -3, 4 )
We have to find the coordinates of the recycle bin.
Let us consider the equation of the circle,
[tex]x^{2} +y^{2}+Dx + Ey+ F =0[/tex]
So putting the values of the coordinates into the equation,
First Equation,
[tex]1^{2}+1^{2} + D + E + F = 0[/tex]
Second Equation,
[tex]1^{2} +4^{2} +D + 4E + F=0[/tex]
Third Equation,
[tex](-3)^{2} + 4^{2} - 3D+4E+F=0[/tex]
Subtracting the first equation from the second,
[tex]1^{2} +4^{2} +D + 4E -E=0[/tex]
15 + 3E = 0
3E = -15
E = -5
Subtracting the third equation from the second,
1 + 16 - 9 - 16 + D + 3D = 0
4D = 8
D = 2
Putting the values of E and D in the first equation,
1 + 1 + D + E + F = 0
F = -2 - D - E
F = 1
So now the equation of the circle becomes,
[tex]x^{2} +y^{2}+2x - 5y+ 1 =0[/tex]
By expanding the above equation we can find the standard equation,
[tex]x+2x+1^{2} +y^{2} -5y+ 2.5^{2}- 1^{2} -2.5^{2} +1 =0[/tex]
[tex](x+1)^{2} + (y - 2.5)^{2} = 1^{2} + 2.5^{2} -1[/tex]
[tex](x+1)^{2} + (y - 2.5)^{2} = 2.5^{2}[/tex]
So the required circumcenter will be = ( -1, 2.5 )

Answers
Step-by-step explanation:
Let the larger angle be x.
Smaller angle = x - 8
As both angles are supplementary,
x + (x - 8) = 180°

2x = 188°
x = 94°
Therefore, larger angle = 94°
Smaller angle = 94° - 8° = 86°

What is a a reflection?A glide reflection or transflection is a symmetry operation in two-dimensional geometry that combines a reflection over a line with a translation along that line into a single operation.
An exchange of points from one side of a line with points on the other side of the mirror at the same distance from the mirror occurs when a mirror line is fixed in the plane. There is a mirror line in every reflection. A mirror reflection is followed by a translation that is parallel to the mirror to create a glide reflection.
Here, the shape is mirrored in the reflection. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another.
In conclusion, based on the information given, it should be noted that the correct option is B.
