Identify the kind of sample that is described. A researcher asked a simple random sample of home-schooled children, a simple random sample of children who attend private school, and a simple random sample of children who attend public school their opinion on the new town curfew.
Answer:
stratified sample
Step-by-step explanation:
The kind of sample that is being described is known as a stratified sample. This would be the type of sample because the researchers are dividing the entire student population that exists into various different categories or groups. The groups that have been created are home-schooled students, private school students, and public school students. All of the students are still part of the student population and therefore represent their groups.
A store manager buys binoculars for $45 each. He marks up the cost by 40% to get the store price. Then the store has a sale and the store price is reduced by 10%. What is the sale price of the binoculars?
Answer:
$56.70
Step-by-step explanation:
The cost plus markup is found by multiplying $45 by 1.40: $63.
With the 10% price reduction, the sale price is 0.90($63) = $56.70.
Regarding 1.40: the '1' results in the full price to the manager plus the '0.40' markup.

Plerson's science grades were 95,87, 75,78, 84, and 97.
What was the average of her grades?
Answer:
The average is 86
Step-by-step explanation:
so you have to take all the numbers and add them together, the answer of all the numbers together should be: 516. Then you divide 516 by 6 which equals 86.
So the average of 95,87,75,78,84, and 97 is 86

Wen and five friends equally share 1/3 of a pan of snack bars. Which expression shows how much of the pan each person gets?
Answer:
Step-by-step explanation:
I'm pretty sure the expression is 1/3 ÷ 6
This is because there are 6 friends in all and you are splitting 1/3 of the pan snack bars to each of them.
So, what your splitting/cutting/dividing would be the dividend (1/3) and then the friends would be the divisor (6)
Today, 198 people went to Six Flags the first hour it was open. This number was 30% of the number of people who went to the park yesterday. How many people went to the park YESTERDAY?
Its 660
there would be 198 people if you take 30% of 660
Answer:
660
Step-by-step explanation:
30% = 198 (People for the first hour it was open)
1% = 6.6 (1% for people at the park yesterday)
100% = 6.6 x 100 = 660 (Everybody at the park)

If the value of a quarter of a kilogram is ₹ 40, how much money will be the value of 100 grams?
Answer:
₹16
Step-by-step explanation:
1/4 kg = ₹ 40
1kg = 40×4 = ₹160
1000g = 1kg
100g = 100/1000 kg
= 0.1kg
0.1kg= 0.1×160 = ₹16

What kind of triangle is 15,16,21
Answer:
here is my answer is took me alot of time
Step-by-step explanation:
The calculator solves the triangle specified by three of its properties. Each triangle has six main characteristics: three sides a, b, c, and three angles (α, β, γ). The classic trigonometry problem is to specify three of these six characteristics and find the other three. Of course, our calculator solves triangles from any combinations of main and derived properties such as area, perimeter, heights, medians, etc. Usually by the length of three sides (SSS) or side-angle-side or angle-side-angle.
How does this triangle calculator solve a triangle?
The calculation of the general triangle has two phases:
expert phase - which is different for different tasks. From the entered data, the calculator tries to calculate the sizes of three sides of the triangle. He gradually applies the knowledge base to the entered data, which is represented in particular by the relationships between individual parameters of the triangle. These are successively applied and combined, and the parameters of the triangle calculate. Calculator iterate until the triangle has calculated all three sides.
For example, from the given area of the triangle and the corresponding side, the appropriate height is calculated. From the known height and angle, the adjacent side, etc., can be calculated. They use knowledge, e.g., formulas (relations) Pythagorean theorem, Sine theorem, Cosine theorem, Heron's formula, solving equations and systems of equations.
The second stage is the calculation of the properties of the triangle from the known lengths of its three sides.
Examples of how to enter a triangle:
All the sides of the triangle are different and do not satisfy Pythagoras' theorem. Then the triangle is a scalene triangle.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
The dimensions of the triangle are 15, 16, and 21.
Check whether it satisfies the Pythagoras theorem or not. Then we have
H² = P² + B²
21² = 16² + 15²
441 = 256 + 225
441 ≠ 481
Every one of the sides of the triangle is unique and doesn't fulfill Pythagoras' hypothesis. Then the triangle is a scalene triangle.
