Step-by-step explanation:
300 x 8/100 x 1
=24
=(24+300)=324
=9930-324=9606
Answer:
Negative Slope.
-7/5
Step-by-step explanation:
Decreasing from left to right.
x = 3- -2 = 5
y = -2 - 5 = -7
y = -7/5x + 11/5
Answer:
y > 6 or y < -3
Step-by-step explanation:
y² - 3y > 18
Complete the square.
y² - 3y + 9/4 > 18 + 9/4
y² - 3y + 9/4 > 81/4
(y - 3/2)² > 81/4
y - 3/2 > 9/2, or y - 3/2 < -9/2
y > 6 or y < -3
Answer:
The 80% confidence interval for difference between two means is (0.85, 1.55).
Step-by-step explanation:
The (1 - <em>α</em>) % confidence interval for difference between two means is:

Given:

Confidence level = 80%

*Use a <em>t</em>-table for the critical value.
Compute the 80% confidence interval for difference between two means as follows:

Thus, the 80% confidence interval for difference between two means is (0.85, 1.55).
