Given:
Amount = 8700
Time = 3 years
Rate of interest = 24% per annum
To find:
The principal values.
Solution:
Formula for amount:

Where, A is amount, P is principal, r is the rate of interest and t is the number of years.
Putting
, we get




Divide both sides by 1.906624.



Therefore, the principal value is about 4563.04.
Since the graph is a straight line, its equation is of the form;

Where m is the slope and c is the y intercept
We can use any two points on the straight line to find the value of m and c.
Let us use (0,30) and (4,150)

This simplifies to,

Let us substitute the value of m to obtain,

Substitute any of the points to find c. It is easier to use (0,30).


The equation of the graph now becomes,

So in 10 weeks Ben will collect,



Ben will collect 330 papers.
You can also use any two points to find the equation of this line.
Answer:
87.29%
Step-by-step explanation:
Given: Mean= 68.8 inches
Standard deviation= 2.8 inches
Now, finding the percent of the men in the sample were greater than 72 inches.
We know, z-score= 
z-score= 
⇒ z-score= 
∴ z-score= 1.14
Next, using normal distribution table to find percentage.
Coverting 0.8729 into percentage= 
We get the percentage as 87.29%
Hence, 87.29% of the men in the sample were greater than 72 inches.
Answer: YES
<u>Step-by-step explanation:</u>
8p - 2q = 14
8(1) - 2(-3) = 14
8 - -6 = 14
8 + 6 = 14
14 = 14
TRUE
