Answer:
$72,100
Step-by-step explanation:
To calculate the total principal+interest payment, you can use the formula to find the future value:
FV=PV(1+i)^n
FV= Future value
PV= Present value= $58,200
i= Interest rate= 7.40%
n= Number of periods of time= 3 years
Now, you can replace the values on the formula:
FV=58,200*(1+0.0740)^3
FV=58,200*(1.0740)^3
FV=72,100
According to this, the answer is that the total principal + interest payment will be $72,100.
Answer: X< -9
Step-by-step explanation: 7+2x<-11 move the constant to the right and change its sign. 2x<-11-7. Now calculate the difference, which should get to... 2x<-18. Then you just divide both sides of the inequality by 2. Which should get your answer.... X< -9
Answer:
130g
Step-by-step explanation:
Answer:
Step-by-step explanation:
Information provided
n=100 represent the random sample taken
X=21 represent the number of bags overfilled
estimated proportion of overfilled bags
is the value that we want to test
z would represent the statistic
Hypothesis
We need to conduct a hypothesis in order to test if the true proportion of overfilled bags is higher than 0.15.:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is:
(1)
And replacing the info given we got:
Answer:
x =8
y = 4sqrt(2)
z = 4sqrt(2)
Step-by-step explanation:
The easiest one to calculate is x
If it is a 45 -45-90 degree triangle then AB = BC=x
Since AB =8 then BC =8 and x=8
The next easiest to calculate is z
If it is a 45 -45-90 degree triangle then AD = BD=z
Using the Pythagorean theorem
z^2 +z^2 = 8^2
2z^2 =64
Divide by 2
x^2 = 32
Taking the square root of each side
z = sqrt(16)sqrt(2)
z=4sqrt(2)
Finally, we can find y
If it is a 45 -45-90 degree triangle then BD = DC
BD =z =4 sqrt(2) = DC = y
Therefore y =4 sqrt(2)
