Answer:
B) 0.9, 0.45, -0.77, -0.95
Explanation:
The correlation coefficient is a statistical measure that indicates the strength of the relationship between two variables. The value usually ranges from -1 to 1 where:
• 1 indicates a strong positive relationship.
,
• -1 indicates a strong negative relationship.
,
• A result of 0 indicates no relationship at all.
Therefore, the given correlation coefficients classified from the strongest to the weakest is:
![0.9,0.45,-0.77\text{ and -0.95}](https://tex.z-dn.net/?f=0.9%2C0.45%2C-0.77%5Ctext%7B%20and%20-0.95%7D)
The correct choice is B.
Answer: 70 meters
Step-by-step explanation:
Hi, since the situation forms a right triangle and a rectangle, we have to apply the Pythagorean Theorem (for the triangle)
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle (the longest side) and a and b are the other sides.
Replacing with the values given:
65^2 = 16^2 + x^2
4,225 = 256 + x^2
4,225-256 = x^2
3,969=x^2
√3,969 =x
63=x
We have calculated the missing side of the triangle, now we have to add the height of the rectangle:
63 +7 =70 meters

Answer:
The following numbers ARE functions:
2, 3, 6, 7, 9, 12
Step-by-step explanation:
A function is only possible if the x values have NO REPEATING NUMBER!!!
Every number that isn't mentioned above has at least 1 number in it's x-values that repeats.
<u>Question 1</u> has the 8 and 4 with 2 numbers.
<u>Question 4</u> the 3 repeating. (There are 2 dots over the 3)
<u>Question 5</u> has numbers 1 and 5 repeating many times
<u>Question 8</u> numbers 1 and 2 are repeated twice
<u>Question 10</u> number 3 repeats twice
<u>Question 11</u> has the 1 repeated
Answer:
The total earning of commission on sales of 85, 000 will be:
![3500+1050=4550](https://tex.z-dn.net/?f=3500%2B1050%3D4550)
Step-by-step explanation:
- Total sales earning = 85,000
As salesperson earns 5% commission the first 70,000.
![\frac{5}{100}\:\times \:70\:000=3500](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B100%7D%5C%3A%5Ctimes%20%5C%3A70%5C%3A000%3D3500)
As the salesperson earns 7% commission on the sales over 70,000.
As 15000 is the sales earning on which he will get commission 7%.
Because
So the 7% earning of salesperson will on 15000 will be:
![\:\frac{7}{100}\:\times \:15\:000=1050](https://tex.z-dn.net/?f=%5C%3A%5Cfrac%7B7%7D%7B100%7D%5C%3A%5Ctimes%20%5C%3A15%5C%3A000%3D1050)
Therefore, the total earning of commission on sales of 85, 000 will be:
![3500+1050=4550](https://tex.z-dn.net/?f=3500%2B1050%3D4550)
