Answer:
-1.00
Step-by-step explanation:
Given that a publisher reports that 45% of their readers own a laptop. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage.
Sample size n =190
Sample proportion p = 0.41
(Two tailed test )
Assuming H0 to be true
std error =
p difference = -0.04
Test statistic = p differencce/std error
= -1
Hence test statistic is -1.00
Answer:
x = 5/2, y = -1
x*y = 5/2*-1 = -5/2
Step-by-step explanation:
First we solve the system
2x-5y = 10
x = 5 + 5y/2
4x + 3y = 7
4(5 + 5y/2) + 3y = 7
20 +10y + 3y = 7
-13 = 13y
y = -1
Now go back to the other equation
2x - 5y = 10
2x - 5(-1) = 10
2x + 5 = 10
2x = 5
x = 5/2
Now we multiply x and y together
- 11s² - 21st
- 4st - t²
- 2x² + x³
- 2x + 2
- 9x - 3s - 2t
