does the graph represents a function
In this situation, we would use something called the vertical line test. In other words, if we can draw a vertical line that passes more than one point on the graph, then the relation is not a function.
If we use the vertical line test in this situation, it is not possible to draw a vertical line that passes through more than one point. Therefore, this does represent a function.

The mean score of a competency test is 82, with a standard deviation of 2. Between what two values do about 99.7% of the values lie?
Answer:
99.7% lies between 76 and 88
Step-by-step explanation:
mean = 82, standard deviation = 2
3 standard deviation has 99.7%
so we need to find 3 standard deviation above and below the mean.
To find 3 standard deviation above the mean , we add standard deviation 2 with mean
82 + 2= 84 first SD
84 + 2= 86 second SD
86 + 2= 88 third SD
88 is the third SD above the mean 82
To find 3 standard deviation below the mean , we subtract standard deviation 2 from mean
82 - 2= 80 first SD
80 - 2= 78 second SD
78 - 2= 76 third SD
76 is the third SD below the mean 82
So , 99.7% lies between 76 and 88

What is the MAD of the data set?
{13, 6, 3, 7, 11}
Enter your answer in the box.
The MAD value of the given data set is "3.2".
Mean absolute deviation (MAD)The average distance between each data value and the mean is defined as the mean absolute deviation of a data set. It is a measure of variation in a data set.
Calculation of the MAD value:
Given:
[tex]\to \{ 13, 6, 3, 7, 11\} \\\\[/tex]
Calculating the sum of the given value:
[tex]\to 13 + 6 + 3 + 7 + 11 = 40\\\\[/tex]
Calculating the average value:
[tex]\to \frac{40}{ 5} = 8\\\\[/tex]
Subtracting the average value from the given set:
[tex]\to 13 - 8 = 5\\\\\to 6 - 8 = | -2 | = 2\\\\\to 3 - 8 = | -5 | = 5\\\\\to 7 - 8 = | -1 | = 1\\\\\to 11 - 8 = 3\\\\[/tex]
Calculated set value:
[tex]\to 5, 2, 5, 1, 3\\\\[/tex]
Adding the set value:
[tex]\to 5 + 2 + 5 + 1 + 3 = 16[/tex]
Calculating the average value of the set:
[tex]\to \frac{16}{5} = 3.2\\\\[/tex]
So, the
[tex]\to \text{MAD} = 3.2[/tex]
Therefore, the final value of MAD is "3.2"

Step-by-step explanation:
In the coordinate plane, what is the length of the line segment that connects points at (4, −1) and (9, 7) ? Enter your answer in the box. Round to the nearest hundredth.
Final answer:
The length of the line segment connecting points (4, -1) and (9, 7) in the coordinate plane is approximately 9.43 units, when rounded to the nearest hundredth.
Explanation:
To find the length of the line segment that connects the points (4, −1) and (9, 7) in the coordinate plane, we can use the distance formula which is derived from the Pythagorean theorem:
The distance (Δ) between two points (x1, y1) and (x2, y2) is given by:
Δ = √((x2 - x1)² + (y2 - y1)²)
Substituting the given coordinates:
Δ = √((9 - 4)² + (7 - (−1))²)
Δ = √(5² + 8²)
Δ = √(25 + 64)
Δ = √89
Using a calculator, we can find that:
Δ ≈ 9.43
Therefore, the length of the line segment is approximately 9.43 units, rounded to the nearest hundredth.
2. WALKING Laura starts at the origin. She walks 8 units to the right and then 12 units up. How far away from the origin is she? Round your answer to the nearest tenth
Final answer:
Laura is approximately 14.4 units away from the origin after walking 8 units to the right and 12 units up, found by applying the Pythagorean theorem.
Explanation:
The question asks how far Laura is from the origin after walking 8 units to the right and 12 units up. To solve this, we can use the Pythagorean theorem, which is a fundamental principle in geometry that deals with the lengths of sides in a right-angled triangle. Here, we consider Laura's walk as the two perpendicular sides of a triangle, with her movement to the right representing the horizontal side (8 units) and her movement upwards representing the vertical side (12 units).
To find the distance (hypotenuse) from the origin, we apply the Pythagorean theorem as follows:
Calculate the square of both the horizontal and vertical distances: 8^2 = 64 and 12^2 = 144.Add the squares of the two sides: 64 + 144 = 208.Take the square root of the sum to get the hypotenuse: sqrt(208) ≈ 14.4 units.Hence, Laura is approximately 14.4 units away from the origin, rounded to the nearest tenth.

find the greatest common factor of the following monomials 26n5 12n2
Final answer:
The greatest common factor of 26n^5 and 12n^2 is 2n^2, as the prime factor 2 and the variable n to the second power are the highest powers common to both monomials.
Explanation:
The greatest common factor (GCF) of two monomials, 26n5 and 12n2, is found by identifying the highest power of each prime factor that is present in both monomials. To find the GCF of 26 and 12, we factor both numbers into their prime factors:
26 = 2 × 1312 = 22 × 3Since 2 is the only common prime factor between 26 and 12, and its lowest power in both numbers is 21, we take this as part of our GCF. For the variable part, we look at n5 and n2 and take the lowest power, which is n2. Hence, the GCF of 26n5 and 12n2 is 2n2.

Adelaide paid $35 for a manicure and gave the manicurist a 20% tip How much money did Adelaide give her manicurist
Answer:
Adelaide gave $ 42 to the manicurist.
Step-by-step explanation:
Here, the original price of the manicure = $ 35
Since, 20% tip is given to manicurist,
Thus, the total payment for manicure = Original price of the manicure + 20 % of the original price of the manicure
= 35 + 20 % of 35
[tex]=35+\frac{20\times 35}{100}[/tex]
[tex]=35+\frac{700}{100}[/tex]
[tex]=35+7[/tex]
[tex]=42[/tex]
Hence, Adelaide gave $ 42 to the manicurist.
Jennifer Lopez met her 9 cousins at a family reunion. The number of male cousins (x) was 2 less than the number of females cousins (y)
To find the number of male and female cousins Jennifer Lopez met at a family reunion, we can set up a system of equations based on the given information. By solving the system, we can determine the values of the variables and find the answer.
Explanation:The subject of this question is Mathematics and the grade level is Middle School. The question asks about the number of male and female cousins Jennifer Lopez met at a family reunion. Let's define the number of male cousins as x and the number of female cousins as y. From the given information, we know that x is 2 less than y.
So the equation can be written as: x = y - 2
Since Jennifer met a total of 9 cousins, we can write another equation: x + y = 9
Now we can solve this system of equations to find the values of x and y. Subtracting the first equation from the second equation, we get: (x + y) - (y - 2) = 9 - (y - 2)
Simplifying further, we have: x + 2 = 11 - y
Bringing the variables to one side, we get: x + y = 11 - 2
Combining like terms, we have: x + y = 9
Therefore, the value of x is 4 and the value of y is 5. So Jennifer Lopez met 4 male cousins and 5 female cousins at the family reunion.

a hippopotamus weighs 1.5 tons. What is its weight in ounces?
We can use unitary method here.
First let us use the basic conversion from tons to ounces.
1 ton =32000 ounces
Now we have to find how many ounces are there in 1.5 tons.
Weight of hippopotamus in tons =1.5 tons
Weight of hippopotamus in ounces = 1.5 *32000 = 48000 ounces.
So the weight of hippopotamus in ounces is 48000 ounces.
