3,000,000 is the answer
y = 8x + 23
How many shirts would you have to purchase for the total cost to be the same at both companies?
Answer:
5 shirts
Step-by-step explanation:
Y=12x+3 equation 1
y=8x+23 equation 2
12x+3=8x+23 substituting y value will cause equations to equal
4x=20
x=5 shirts
check answer
y=12x+3
y=12(5)+3
y=60+3
y=63
y=8x+23
y=8(5)+23
y=40+23
y=63
15 hours and 15 minutes
5 hours and 15 minutes
4 hours and 15 minutes
If you would like to find the elapsed time between 11:50 a.m. and 4:05 p.m., you can calculate this using the following steps:
12:00 p.m. - 11:50 a.m. = 0:10
12:00 p.m. + 4:05 p.m. = 4:05
0:10 + 4:05 = 4:15 = 4 hours and 15 minutes
The correct result would be 4 hours and 15 minutes.
Answer:
4 hours and 15 minutes
Step-by-step explanation:
A. It must be between -1 and 1.
B. It must be positive.
C. It indicates the percentage of points that lie on the regression line.
D. The correlation coefficient tells you how strong the residuals are.
E. If correlation is positive, the slope of the regression line is also positive
This is about knowledge between Correlation and Regression.
Option A and E are correct.
Option A; Under different types of correlation coefficient they tend to make use of different range for their definitions but it is always between minimum of -1 and maximum of 1. Thus, the statement is correct.
Option B; It must not be positive because as stated in option A above negative values can be used.
Option C; No, it doesn't indicate percentage of points because in the definition i gave earlier, there is nothing like that. Besides, this is in regression and not correlation.
Option D; This is incorrect as the definition doesn't support it.
Option E; This is correct because positive correlation means that the two variables increase at the same time or decrease at the same time. Thus, it means the regression line will be positive as long as correlation is positive.
