Statistic exists a number that designates as numerical data. Average number of all high school graduates who will attend college
What is Statistic?Statistic exists a number that designates as numerical data. Statistics exist described as numerical data and is the field of math that negotiates with the collection, tabulation, and interpretation of numerical data. An illustration of statistics exists as a report of numbers expressing how many followers of each religion there exist in a certain country. Numerical data exists as a data kind described in numbers, rather than natural language description. Sometimes named quantitative data, numerical data exists ever gathered in number form.

Answer:
3. 1.8
4. 66
Step-by-step explanation:
3.The common difference is the difference between a term and the one before it.
5 -3.2 = 1.8
The common difference is 1.8.
__
4.The 8th term is found by putting 8 where n is and doing the arithmetic.
a₈ = 10·8 -14
a₈ = 80 -14 = 66
The eighth term is 66.
_____
Additional comments
The difference is only "common" if all pairs of adjacent terms have the same difference. When that is the case, any pair of adjacent terms can be used to find the common difference. The arithmetic is probably easier using ...
6.8 -5 = 1.8

In question 4, the sequence has a first term of -4 and a common difference of 10. The sequence is ...

Answer:
They are similar using the angle-angle property.
Step-by-step explanation:
Since you know that 2 of the angles are congruent, you can use this to prove triangle similarity.
By AA similarity, triangle PQR similar to triangle STU.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
The two given triangles PQR and STU.
Here, ∠P=63° and ∠R=45°
In triangle STU, ∠S=63° and ∠U=45°
Now, ∠P=∠S=63° and ∠R=∠U=45°
Since angles of triangle are congruent
By AA similarity, ΔPQR similar to ΔSTU
Therefore, triangles are similar.

A school is getting repainted. The painters arrive with 73 gallons of paint, and they will use 2 gallons to paint each classroom. After the painters finish painting all the classrooms, they will have 37 gallons of paint left. How many classrooms are there?
Write and solve an equation to find the answer.
_____classrooms
Answer:
___18___ classrooms
Step-by-step explanation:
Let the number of classrooms be x.
Each classroom uses 2 gallons, so x classrooms use 2x gallons.
They paint x classrooms using 2x gallons.
They still have 37 gallons left, so the entire amount of paint they had before they started painting was
2x + 37.
We are told they started with 73 gallons, so 2x + 37 must equal 73.
The equation is
2x + 37 = 73
Now we solve the equation.
Subtract 37 from both sides.
2x = 36
Divide both sides by 2.
x = 18
Answer: ___18___ classrooms

A bag of chips contains 621 calories and serves 4.5 people. How many calories are in each serving?
Answer:
138 calories/serving
Step-by-step explanation:
Find the unit rate, the measure of how many calories are in each serving:
621 calories
-------------------- = 138 calories/serving
4.5 servings
The number of calories are in each serving is 138.
Given that, a bag of chips contains 621 calories and serves 4.5 people.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Number of calories in each serving = Total number of calories/Number of servings
= 621/4.5
= 138 calories
Therefore, the number of calories are in each serving is 138.

Two similar triangles are shown below which two sets of angles are corresponding angles p and q
Answer: p = 30 q = 30 (if not touching edge of hexagon but if it is touching edge one of the pairs) then p or q = 120 and p and q = 30
Step 1) Sum of an interior angle of a polygon = 720 degree where n = 6 as 6 exterior sides = (n-2) * 180 = (6-2) * 180 = 4 * 180 = 720 degree Where the measure of each angle of a hexagon = 720/ 6 = 120 degree Step 2) Then show 3 angle letter names = 180 degree Step 3) Angle name letters + 2 angle (other two names letters inside within triangle) add up to 180 degree Step 3) State since triangle name (of all letters within one triangle) is Isosceles Step 4) Triangle (state same triangle letters with number 2 in front) = 180 - 120 = 60 then state triangle (letter name) / 2 = 30 degrees obviously the 120 and 60 differentiates if not a hexagon to a pentagon if not a hexagon = (3 *180) / 5 = 108 then due to isosceles (180 - 108)/ 2 = 72/2 = 36 degree for a pentagon or 30 degree each for p + q for a hexagon etc
