We are given
P = $754.43
r = 13.6% annual
for a.
A = 150
for b.
A = 300
First, change the interest into effective monthly
i = (1 + 0.136/12)^12 - 1
Solve for i
Next, use the general formula
A = P i ( 1 + i)^n / (1 + 1)^n - 1
Subsitute P, i, and A for a and b.
Then, solve for n for a and b.
<u>Answer:</u>
If the circumference of a circle is changed from 9 cm to 3 cm, then the diameter decreases by a factor of 3.
<u>Solution:</u>
Given, the circumference of a circle is changed from 9 cm to 3 cm,
We have to find how will the diameter change from the given equations?
We know that, diameter = 2 
radius and circumference = 2π radius.
Hence, the diameter decreases by a factor of 3.
Since the slope is (change in y)/(change in x), and a negative number over a positive number is negative (and vice versa), we want to figure that out. Therefore, we would want 2 to be bigger than the x value and 8 smaller than the y value, or the other way around. (0,9) fits the description, as well as (5, 6)
To find the variance, you must square the standard deviation, or <span>σ.
</span>
<span>σ = 23.9
The variance is
</span>
<span>σ²= 23.9² = 571.21

Answer:
B
Step-by-step explanation:
3x - 3 > 42
3x - 3 42
+3 + 3
3x > 45
3x / 3 45/3
x > 15
x can be 16
