Well half of 500 is 250 so one person gets 300$ and the other gets 250$
Formula for compound interest is
Interest = Amount - Principal
Interest = - P
Where r = rate in percent
t = time in years
For Jaina,
P = $300
r= 7%
t = 3 yrs
So, Interest = - 300
For Tomas
P = $400
r= 4%
t = 3 yrs
So, Interest = - 400
So pair of equations for Jaina and Tomas are
Interest = - 300
Interest = - 400
Answer:
18 square units
Step-by-step explanation:
By counting grid squares or finding the difference of horizontal and vertical coordinates, you can determine that the rectangle is 2 units wide by 9 units tall. The area is the product of these dimensions:
A = LW = (9 units)(2 units) = 18 units^2
N-10=5-4n
n+4n=5+10
5n=15
n=3
Answer:
Fail to reject the null hypothesis.
Step-by-step explanation:
The hypothesis test is conducted for Boston public school. They have used z-value table and the value of test statistics is 1.20. AT the significance level of 0.05, the null hypothesis is accepted. We cannot reject the null hypothesis. The p-value is greater than alpha so there is no evidence to support the claim of Boston Public School.
