Answer:
She spent about 25% of the money on a dress.
Answer:
103.5
Step-by-step explanation:
13 + (43 ÷ 2) × 5 - 17
13 + 21.5 × 5 - 17
13 + 107.5 - 17
107.5 - 4
103.5
Answer:
The correct statement is (B).
Step-by-step explanation:
The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.
If there is any alteration in the value of one variable, the value of the other variable is altered in a fixed proportion. The correlation amid them is known as perfect correlation.
In statistics, a perfect positive correlation is represented by +1 and -1 indicates a perfect negative correlation.
Positive correlation is an association amid two variables in which both variables change in the same direction.
A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.
Negative correlation is a relationship amid two variables in which one variable rises as the other falls, and vice versa.
A correlation coefficient of 0 implies that there is no relationship between the two variables.
Thus, the correct statement is (B).
Since coefficient of x^2 is prime and both second and third term are positive, it must be in form (3x+_)(x+_).
There is three possibles for these blank spaces;
1,4
2,2
4,1
Because coefficient of second term is 13 = 1+12 = 1+3*4, these blank space should be 1,4
So your answer is (3x+1)(x+4)
Hope this makes sense.
