6 integers that satisfy the given condition are 10,11,12,13,14,15.
Inequality is a relation that makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size
we have the number X
Of which the square root is greater than 3 and less than 4

Vivian and Kyle each want to run for president of their school's student body council. In order to do so, they must collect a certain number of signatures and get a nomination. So far, Vivian has 18 signatures, and Kyle has 14. Vivian is collecting signatures at an average rate of 1 per day, whereas Kyle is averaging 3 signatures every day. Assuming that their rate of collection stays the same, eventually the two will have collected the same number of signatures. How long will that take? How many signatures will they both have?
The number of days it take the same number of signature will be 2 days.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Vivian has 18 signatures, and Kyle has 14.
Vivian is collecting signatures at an average rate of 1 per day, whereas Kyle is averaging 3 signatures every day.
Now,
Since, Vivian has 18 signatures, and Kyle has 14.
And, Vivian is collecting signatures at an average rate of 1 per day, whereas Kyle is averaging 3 signatures every day.
Let number of days it take the same number of signature = x
So, We can formulate;
⇒ 18 + x = 14 + 3x
Solve for x as;
⇒ 18 + x = 14 + 3x
⇒ 18 - 14 = 3x - x
⇒ 4 = 2x
⇒ 2x = 4
⇒ x = 2
Thus, The number of days it take the same number of signature will be 2 days.

a rectangular field measures 90 meters by 162 meters. what will it cost to cover the field with pallets of grass each covering 90 squard yards and costing $213 per pallet
The cost of covering the field with grass pallets is $40996.58.
Given that the rectangular field measures 90 m and 162 m.
Hence, the area of the field is 90 X 162 m²
The grass pallets are sure in shape with an area covering 90 square yards.
1 m = 1.09 yards
Hence,
1 m² = 1.09² square yards
Hence,
90 X 162 m² = 90 X 162 X 1.09² square yards
Hence the number of pallets to be used is
(90 X 162 X 1.09²) / 90
= 162 X 1.09² pallets.
= 192.4722 pallets.
1 pallet costs $213
Hence,
192.4722 pallets cost
192.4722 X 213
= $40996.58
Therefore we get the cost of covering the field with grass is $40996.58.

Which of these strategies would eliminate a variable in the system of equations?
The strategy which would eliminate a variable in the system of equations is to multiply the top equation by 3 ,multiply the bottom equation by -2 then add the equation and is denoted as option B.
What is Equation?This is a mathematical term which is made up of two expressions and is connected by an equal sign.
In the example given below:
2x + 8y = -3
3x + 6y = -4
We can multiply the top by 3 and the bottom by -2 which will result in:
6x + 24y = -9
-6x - 12y = 8
They are then added to each other to give:
6x - 6x + 24y - 12y = -9+8
12y = -1
y = -1/12
From this we can notice that the variable x was eliminated which is why option B is the correct choice.

The television antenna makes an angle 90 with the ground
The height of the antenna is 10 feet
The wires are anchored to the base which is 8 feet
We need to calculate the length of the wires
The height of the wire can be calculated by using pythagoras theorem
h² = b² + p²
h² = 8² + 10²
h² = 64 + 100
h = √164

The effect of eliminating the lowest value, 0, from the data set have on the mean and median of the data set is;
There is a difference of 7.5 between the mean without 0 and mean with 0There is a difference of 2.5 between the median without 0 and median with 0What is mean and median?The mean of a given data is the sum of all observations divided by the number of observations
The median of a given set of data refers to the middlemost observation, obtained after arranging the data in ascending or descending order.
Given data:
0, 40, 60, 70, 75, 80, 85, 95, 95, 100
a) Mean without '0' = (40+ 60+ 70+ 75+ 80+ 85+ 95+ 95+ 100) / 9
= 700/9
= 77.777
Median without '0' = 40, 60, 70, 75, 80, 85, 95, 95, 100
= 80
Mean with ' 0' = 0+ 40+ 60+ 70+ 75+ 80+ 85+ 95+ 95+ 100 / 10 = 70
Median with '0' = 0, 40, 60, 70, 75, 80, 85, 95, 95, 100
= (75 + 80) / 2
= 77.5
So therefore,
Difference in mean = Median without '0' - Mean with ' 0'
= 77.77 - 70
= 7.7
Difference in median = Median without '0' - Median with '0'
= 80 - 77.5

Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 1 ) and (x₂, y₂ ) = (6, 3 )
m = [tex]\frac{3-1}{6-(-2)}[/tex] = [tex]\frac{2}{6+2}[/tex] = [tex]\frac{2}{8}[/tex] = [tex]\frac{1}{4}[/tex] , then
y = [tex]\frac{1}{4}[/tex] x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (6, 3 ) , then
3 = [tex]\frac{3}{2}[/tex] + c ⇒ c = 3 - [tex]\frac{3}{2}[/tex] = [tex]\frac{3}{2}[/tex]

What is the value of the product 2/3 x 9/5?
Answer:
[tex]\frac{6}{5}[/tex]
Step-by-step explanation:
[tex]\frac{2}{3} *\frac{9}{5} =\frac{18}{15} =\frac{6}{5}[/tex]
The value of the product of 2/3 × 9/5 is 6/5.
In the given question, we have to attempt fraction multiplication.
For fraction multiplication, we simply multiply the respective numerators and denominators with each other.
Here, in 2/3 × 9/5 ⇒ 18/15 (since 2×9=18) (since 3×5=15)
Now, since we can see that both the numerator and denominator in the solution can get divided by 3, we can simplify the fraction by dividing both the numerator and denominator by 3.
On dividing by 3, we get ⇒ 6/5
So, on multiplying 2/3 and 9/5, we get 18/15 which we later simplify into 6/5.

Decide whether events A and B are overlapping or non-overlapping, you roll a red die and a blue die. event a is that you get a sum of 9. event b is that you get a double.() overlapping ()non-overlapping
Events A and B are non-overlapping. Option(2) is correct.
When two sets A and B have at least one element in common, they are said to be overlapping.
The sets of photographs that don't overlap are the sets where no two pictures (correctly) don't overlap. They are the expansion of the cross-bifix-free sets of strings to two dimensions is called non-overlapping.
A red die and a blue die are rolled.
Assume that Event A is receiving the number 9.
Event B: You receive a double.
Whether events A and B overlap or not is what we want to determine.
When two red dice and two blue dice are thrown, a sample space is then provided by,
S = {(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5),(3,6), (4,1), (4,2), (4,3), (4,4),(4,5),(4,6) (5,1), (5,2), (5,3), (5,4),(5,5),(5,6),(6,1), (6,2),(6,3)(6,4),(6,5),(6,6)}
The two dice are rolled, and there are a total of 36 outcomes.
n(S)=36
Assume that Event A is receiving the number 9.
The probable results for A = (3,6), (4,5), (5,5), (5,6), (6,3)
And let's say that you receive a double in Event B.
The events that may occur if B=(1,1),(2,2),(3,3),(4,4),(5,5),(6,6)
We can observe that the two events are distinct from one another since there is no overlap in the potential outcomes of the two events.
Therefore events A and B are non-overlapping
