Between these two points if you use the distance formula you should get 15
Answer:
(2, 5)
Step-by-step explanation:
The x coordinate is the number inside the parentheses, but with the opposite sign, 2
The y coordinate is the number at the end
Answer:
12
40
48
7
Step-by-step explanation:
To solve the equation use inverse operations. When multiplication is present, use division. When division is present, use the reciprocal and multiplication.
3/4 x= 9 x = 9 * 4/3 = 12
5/8 k= 25 x = 25 * 8/5 = 40
a/6 = 8 x = 8*6 = 48
7s = 49 s = 49/7 = 7
2x+19 = x+23
x=4
So the answer is C
To solve the problem we must know about the correlation coefficients.
<h3>What is the
correlation coefficient?</h3>
The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.
- 1 indicates a strong positive relationship.
- -1 indicates a strong negative relationship.
- A result of zero indicates no relationship at all, therefore, independent variable.
The correlation coefficient -0.9847 denotes, "There is a strong negative relationship between x and y".
Given to us
- The correlation coefficient for the data is −0. 9847.
As we can see that the value of the correlation coefficient is 0.9847, therefore, it is close to 1 means the relationship is strong, while the '-' symbol denotes that the relationship is negative.
Hence, the correlation coefficient -0.9847 denotes, "There is a strong negative relationship between x and y".
