Answer: True.
Step-by-step explanation: The motive of all statistical tests is to check whether all the variables or unknown quantities we are using in the test are independent of each other or are related among themselves.
Also, when we write an article, we should always check whether the statistical test we are using is suitable for the type of data concerned or not.
Furthermore, if a statistical test come out to be invalid, then it may be possible that there are some questions that are misinterpreted.
Thus, the answer is true.
Answer:
3 people
Step-by-step explanation:
$51/$17 = 3 people
- We know to start with $51 dollars because that is the total price of the meal.
- We also know each meal costs $17.
- Next, ask youself what we are trying to find? We are trying to find how many people are eating.
- Therefore to find that we need to take our starting amount $51 divided by $17 because that is the cost of 1 meal.
- $51/$17 = 3 people (whole cost/individual cost = # of people)
- To check this take 3 x 17 = 51 (Now we know it is correct)
- If you would like a further explanation please let me know.
Hint: Move the decimal place to the left.

Answer:
Aseem’s : 8.3, Stana’s : 11.6
Step-by-step explanation:
Aseem: x
Stana: 2x-5
X+2x-5=20
3x=25
X = 8.3
The length of Aseem's car is approximately 8.33 and the length of Stana's car is approximately 11.66.
Let's define the length of Aseem's car as x. Stana's car is 5 less than 2 times the length of Aseem's car, so the length of Stana's car can be represented as 2x - 5. The sum of the lengths of both cars is 20, so we can set up the equation x + (2x - 5) = 20. Solving this equation will give us the lengths of Aseem's and Stana's cars.
Combining like terms, we get 3x - 5 = 20. Adding 5 to both sides of the equation, we have 3x = 25. Finally, by dividing both sides by 3, we find that x = 8.33.
The length of Aseem's car is approximately 8.33 and the length of Stana's car is approximately 2(8.33) - 5 = 11.66.

Answer:
54
Step-by-step explanation
You can't find the other sides, it may seem impossible, but you have to look at this problem in a different way. To find the perimeter of any figure you just need to know the top base, bottom base, right side, and left side.
We see that the top base equals to the bottom base as it is a rectilinear figure. You have to treat the side with 8 and side with 5 as one base. So they equal 13. Now do the same for the bottom.
So, 13 + 13 = 26
The right side is equal to the left side as it is a rectilinear figure, so the right side is 4 + 10 = 14. The left side is also 14.
So 14 + 14 = 28
26 + 28 = 54 units
Sorry, if I couldn't explain properly. I tried my best. As it is hard for me to explain in words. If I could draw it out, I could do better.
Answer:
45
Step-by-step explanation:
I broke the sections apart and then added:
14+14=28
13+13=26
26+28=54
a)
8.2 x 6.7÷0.46
The estimated answer is 119.4
Here the number to be solved is
8.2 × 6.7 ÷0.46
8.2× 14.5652
= 119.4347
But here in the question, it is asked to round the number up to 1 significant figure. 1 significant figure means that only one number should be there after the decimal. Some example are
98.7645 ≈98.8
67.787 ≈67.9
Therefore the solution answer is 119.43478, and after rounding it up to 1 significant figure the answer of the solution is 119.4

The question involves rounding off numbers to one significant figure and then performing a mathematical operation. By rounding off the given numbers and performing the operation, we get the value of '112'. However, rounding might affect the accuracy of the result.
The subject of this question is the process of rounding off numbers before you perform a calculation. The question is: By rounding each number to 1 significant figure, calculate the value of '8.2 x 6.7 ÷ 0.46'.
Firstly, we need to round off these numbers. So, '8.2' becomes '8', '6.7' becomes '7', and '0.46' becomes '0.5' when rounded to one significant figure.
Now we will calculate the expression using those rounded numbers.
Therefore, '8 x 7 ÷ 0.5' equals '112'.
So, by rounding each number to 1 significant figure, '8.2 x 6.7 ÷ 0.46' equals '112'.
It's important to note that rounding can affect the accuracy of your results, especially with more complex expressions or equations. In some situations, it's better to perform the calculation first and then round off the final result. This depends on the precision required for the task at hand.
