Answer:
9.57
Step-by-step explanation:
900 / 100 is 9 but then you just have to add the 57 with a decimal at the end
First lets convert the diameter to cm,
2.4 m equals 240 cm, that is by multiplying 2.4 times 100 because 1 meter has 100 cm
then we need to know how to calculate the circumference, and that is by multiplying pi (3.14) times the diameter of the circumference, that is:
circumference = pi*diameter = 3.14*240
circumference = 753.6 cm
that is the solution
1. It is the subset of a group - Group sample.
2. It equally favors all members of a group sample
- Random sample.
3. It collects data on members of a group - Survey.
4. It does not equally favor all members of a group - Biased sample.
5. It includes all members of a group
- Population.
6. It analyzes data collected from a group - Mean.
I have matched all concepts in accordance with statistical use, hope it helps.
Very handy question to know the answer to. I know of no place on the planet that does not have a tax of some sort.
The tax only applies when money changes hands. It does not apply to any discounts
So if you take the deal, the cost is
Cost of 2 pizzas = normal price - the discount.
Cost of 2 pizzas = 2*10.50 - 2.00
Cost of 2 pizzas = 21 - 2
Cost of 2 pizzas = 19.00 dollars.
Not you add on the sales tax. You can do this one of two ways, the long way or the short way.
<u>Long way</u>
Find the sales tax
Tax = % * cost
Tax = (7.5/100) * 19
Tax = 1.425 don't round yet.
Total Cost = purchase + tax
Total Cost = 19.00 + 1.425 = 20.425 Now round. This is a real problem. It depends on what you have been told to do about rounding when 5 is the last digit. I round up. So my answer would be 20.43 <<<<< Answer.
<u>Short Way</u>
Cost = (Price - discount)*(1 + %/100)
Cost = (21 - 2)*(1+ 7.5/100)
Cost = 19 * (1.075)
Cost = 20.425 = 20.43
Answer:
∠ 2 = 60°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles fro 180° for ∠ 2, that is
∠ 2 = 180° - (57 + 63)° = 180° - 120° = 60°
