Answer:
sin(A+B)=sinAcosB+cosAsinB. Putting the values in. sin(A+B)=(4/5)(−3/5)+(3/5)(−4/5). sin(A+B)=−24/25.
Answer:
y = x + 2
Step-by-step explanation:
Slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. Here, b is equal to 2 because the line crosses the y-axis at 2. THe slope is rise over run, or the change in y divided by the change in x. From the two points given, we get 3/3 which is equal to 1. 1x equals x, so this gives us "no slope." Putting it together gives us y = x + 2.
Have a nice day!

Answer:
There is a significant difference between the means of the two population
Step-by-step explanation:
The mean number of catfish caught daily at Lake Martin is 85, with the number of catfish ranging from 75 to 140.
Range = 140 - 75 = 65
The mean number of catfish caught daily at Smith Lake is 104, with the number of catfish ranging from 96 to 183.
Range = 183 - 96 = 87
Difference in mean = 104 - 85 = 19
If the confidence interval includes 0 we can say that there is no significant difference between the means of the two populations, at a given level of confidence
But by considering the mean difference and the value of range, we can say that
There is significant difference between the means of the two population
