Answer:
1. 520
2. 568.125
Step-by-step explanation:
1.
10 per 40 hours + 1.5 overtime
1.5 overtime = 10(1.5) = 15
10 (40) + 15 (8)
= 400 + 120
= 520
2.
11.25 per 40 hours + 1.5 overtime
1.5 overtime = 11.25(1.5) = 16.875
11.25 (40) + 16.875 (7)
= 450 + 118.125
= 568.125
Answer:
a) strong negative linear correlation.
b) Weak or no linear correlation.
c) strong positive linear correlation.
Step-by-step explanation:
The correlation coefficient r measures the strength and direction (positive or negative) of two variables. The correlation coefficient r is always between -1 and 1. When the coefficient r is negative then the direction of the correlation is downhill (negative) and when it's positive then it's an uphill correlation (positive). Similarly, as the coefficient is closer to -1 or 1 the correlation is stronger, with zero being a non linear relationship.
Now back to the question:
a) Near -1: as we said before, this means an strong negative (-1) linear correlation.
b) Near 0: weak or no linear correlation (we cannot say if its positive or negative because we don't know it it's near zero from the right (positive numbers) or the left (negative numbers)
c) Near 1: strong positive (close to +1) linear correlation
Answer:

X is used to represent a variable or any number. This letter can be changed if you'd like
Answer:
399.84
Step-by-step explanation:
408.00 x .98 (2% reduction from 100) = 399.84
B - Since it is a dotted inequality, it would be a equal to and something else. And since it is greater than 3, it would be X is equal to or less than 3
