Answer:
The simple interest formula is I =PrT
Here I = 378, P = 1800, T = 2
substitute
378 =1800*r*2
r = 378/3600 = .105, i.e. 10.5%

Answer:
Step-by-step explanation:
Using the one sample proportion test:
z = (p-P) / √{P (1-P)/n}
Where p = 709/2640= 0.27, P = 0.29, n= 2640
Thus z = (0.27-0.29) / √{0.29 (1-0.29) / 2640}
z = (-0.02) / √{0.29(0.71) /2640}
z = (-0.02) / √0.00007799
z = (0.02) / 0.0088
z = 2.27
To be able to draw a conclusion, lets find the p value at the 0.1 level of significant: p value is 0.2327. The result is significant as the p value is greater than 0.1 thus we will fail to reject the null and conclude that there is not enough statistical evidence to prove that the true percentage of all firms that announced one or more acquisitions during the year 2000 is less than 29%

Answer:
x=-2
y=-3
Step-by-step explanation:
-9x+4y = 6
9x+5y = -33
We will add these together to eliminate x
-9x+4y = 6
9x+5y = -33
----------------
0x +9y =- 27
9y = -27
Divide by 9
9y/9 = -27/9
y =-3
We still need to find x
9x +5y = -33
9x +5(-3) = -33
9x-15 = -33
Add 15 from each side
9x+15-15 =-33+15
9x=-18
Divide by 9
9x/9 = -18/9
x = -2
