The formula is
A=p (1+r)^t
A future value?
P present value 675
R interest rate 0.09
T time 7 years
A=675×(1+0.09)^(7)=1,233.93
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the areaof a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself tofind the area.
Answer:
yes
Step-by-step explanation:
<u>Given</u>:
Let the random variable x is normally distributed with mean
and ![\sigma=5](https://tex.z-dn.net/?f=%5Csigma%3D5)
We need to determine the probability of ![P(X](https://tex.z-dn.net/?f=P%28X%3C80%29)
<u>Probability of </u>
<u>:</u>
The formula to determine the value of
is given by
![Z=\frac{X-\mu}{\sigma}](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7BX-%5Cmu%7D%7B%5Csigma%7D)
Thus, we have;
![P(X](https://tex.z-dn.net/?f=P%28X%3C80%29%3DP%28Z%3C%5Cfrac%7B80-90%7D%7B5%7D%29)
Simplifying, we get;
![P(X](https://tex.z-dn.net/?f=P%28X%3C80%29%3DP%28Z%3C%5Cfrac%7B-10%7D%7B5%7D%29)
![P(X](https://tex.z-dn.net/?f=P%28X%3C80%29%3DP%28Z%3C-2%29)
Using the normal distribution table, the value of -2 is given by 0.0228
![P(X](https://tex.z-dn.net/?f=P%28X%3C80%29%3D0.0228)
Thus, the value of
is 0.0228
Right away we know we don't have fractions; the midpoint is the average of the coordinates, so if it and one endpoint are integers so is the other endpoint.
We can do a kind of point arithmetic:
C = (A+B)/2
2C = A+B
B = 2C - A
B = 2(6,1) - (1,3) = (12,2)-(1,3)=(11,-1)
Answer: That's none of the above, but a typo away from the first choice.
